LOS ANGELES (Reuters) - Voters strongly supported a ballot measure to sharply curtail the number of medical marijuana dispensaries permitted to operate in Los Angeles while boosting taxes on the sale of pot for health reasons, election returns early on Wednesday showed.
The proposal appeared headed for passage. Returns showed 63 percent of voters supporting it compared with 37 percent opposed, after tabulation of more than 40 percent of ballots cast at polling stations on Tuesday, and all of the mail-in ballots received as of last Friday.
Two rival measures seemed likely to be defeated, with "no" votes far surpassing "yes" votes for each.
At least 800 storefront medical cannabis shops are estimated to be operating in Los Angeles, more than in any other U.S. city, and some residents have complained that the dispensaries are a blight on their neighborhoods.
Proposition D, placed on Tuesday's ballot by the City Council, would cap the number of dispensaries allowed to remain open at 135, said Rigo Valdez, director of organizing for the United Food and Commercial Workers Local 770, a union that supports the measure.
The UFCW has sought to expand its reach into the state-sanctioned marijuana industry by organizing dispensary workers. Many of the shops permitted to stay in business under the Proposition D already have union ties, according to the UFCW.
Despite the prospect of greater city controls, campaign officials say many medical marijuana dispensaries have joined the push for local regulation in an effort to gain legitimacy and stave off a potential federal crackdown.
California was the first of 18 states to legalize marijuana use for medical purposes. But pot remains classified as an illegal narcotic under U.S. law, and a number of dispensaries in Los Angeles and elsewhere have been raided or forced to shut down by federal authorities who said the facilities were fronts for large-scale drug trafficking.
Under Proposition D, taxes on medicinal pot would be increased from $50 per $1,000 in gross sales to $60 per $1,000 in gross sales.
Valdez said the push to regulate medical marijuana dispensaries in the city reflects "a community outcry" over proliferation of the facilities.
"I think that if the city attorney and the city of L.A. says, 'We've got this,'" that the federal government stays out" of enforcement in Los Angeles, he said.
PHOENIX (AP) ? An atheist lawmaker's decision to give the daily prayer at the Arizona House of Representatives triggered a do-over from a Christian lawmaker who said the previous day's prayer didn't pass muster.
Republican Rep. Steve Smith on Wednesday said the prayer offered by Democratic Rep. Juan Mendez of Tempe at the beginning of the previous day's floor session wasn't a prayer at all. So he asked other members to join him in a second daily prayer in "repentance," and about half the 60-member body did so. Both the Arizona House and Senate begin their sessions with a prayer and a recitation of the Pledge of Allegiance.
"When there's a time set aside to pray and to pledge, if you are a non-believer, don't ask for time to pray," said Smith, of Maricopa. "If you don't love this nation and want to pledge to it, don't say I want to lead this body in the pledge, and stand up there and say, 'you know what, instead of pledging, I love England' and (sit) down.
"That's not a pledge, and that wasn't a prayer, it's that simple," Smith said.
Mendez said he was just looking for a way to convey his own feelings like other members do when they take the rotation giving the daily prayer.
"I wanted to find a way to where I could convey some message and take advantage of the opportunity that people have when they offer these prayers," he said. "If my lack of religion doesn't give me the same opportunity to engage in this platform then I feel kind of disenfranchised. So I did want to stand up and offer some kind of thing that represented my view on what's going on."
Wednesday's dust-up over religion comes just days after the U.S. Supreme Court agreed to decide whether an upstate New York town is violating constitutional prohibitions on government sanction of religion by offering prayers to open public meetings. The justices will review an appeals court ruling that held that the upstate New York town of Greece, a Rochester suburb, violated the Constitution by opening nearly every meeting over an 11-year span with prayers that stressed Christianity.
Arizona House Speaker Andy Tobin and Senate President Andy Biggs filed a legal brief agreeing with the town's position.
On Wednesday, Tobin said he had no problem with Mendez's prayer.
"From my perspective I didn't see an issue with Mr. Mendez yesterday," said Tobin, R-Paulden. "I can appreciate what Mr. Smith was saying, but I think all members are responsible for their own prayerful lives and I think the demonstration that we take moments for prayer we all do collectively and in our own hearts."
Rep. Jamescita Peshlakai, who represents a northern Arizona district on the Navajo reservation, did take offense. She said Smith's criticism of another member's faith, or lack of it, was wrong.
"I want to remind the House and my colleagues and everybody here that several of us here are not Christianized. I'm a traditional Navajo, so I stand here every day and participate in prayers," even without personally embracing them, said Peshlakai, D-Cameron. "This is the United States, this is America, and we all represent different people ... and you need to respect that. Your God is no more powerful than my God. We all come from the same creator."
Mendez gave the invocation Tuesday while members of the Secular Coalition for Arizona were in the visitors' gallery. He began his remarks by asking fellow lawmakers not to bow their heads but to instead look around at the other men and women in the room, "sharing together this extraordinary experience of being alive and of dedicating ourselves to working toward improving the lives of the people of our state."

LONDON (AP) ? Dozens of Mohandas Gandhi's personal items have been sold at an auction, but a sample of blood purportedly from the Indian independence leader didn't draw high enough bids.
The memorabilia offered by British auction house Mullock's in Ludlow, England, included a handwritten will, a shawl, a pair of worn leather sandals and a rice bowl said to come from the house in India where Gandhi lived from 1917 to 1934.
One item was described as a bit of Gandhi's blood on two glass microscope slides, said to be provided by the leader when he was recovering from an operation for appendicitis in 1924.
Spokesman Richard Westwood-Brookes said bidding for the blood didn't meet the 10,000-pound ($15,155) reserve price. He said about 50 other items took in 287,000 pounds ($435,000) Tuesday.
ORLANDO, Fla. (AP) ? A Chechen immigrant who was being questioned about his ties to one of the Boston Marathonbombing suspects was shot to death by authorities early Wednesday after he lunged at an FBI agent with a knife, officials said.
Ibragim Todashev, a 27-year-old mixed martial arts fighter, was gunned down at his Orlando home during a meeting with the agent and two Massachusetts state troopers, authorities said. The agent was taken to a hospital with injuries that were not life-threatening.
The FBI gave no details on why they were interested in Todashev except to say that he was being questioned as part of the Boston investigation. But some of his former roommates said that Todashev knew one of the Boston bombing suspects, Tamerlan Tsarnaev, from mixed martial arts fighting in Boston and that the FBI was asking about him.
Public records show Todashev lived in Watertown, Mass., just outside Boston, last year.
Tamerlan Tsarnaev, an aspiring boxer, was killed in a shootout with police days after the April 15 bombings. His younger brother, Dzhokhar, survived and is charged with carrying out the attack that killed three people and wounded more than 260.
Investigators have been trying to establish the scope of the plot. In addition, authorities in Massachusetts said they would investigate whether Tamerlan Tsarnaev had any connection to an unsolved 2011 slaying in the Boston suburb of Waltham, where three men were found dead in an apartment, their throats slit and marijuana sprinkled over their bodies. One of the victims was a boxer and a friend of Tsarnaev's.
Todashev had lived on and off with other Chechens in the Orlando suburb of Kissimmee and had moved to Orlando more recently, friends said.
"He's a regular guy, nothing wrong," Saeed Dunkaev said.
Muslin Chapkhanov, another former roommate, said Todashev knew the older Tsarnaev brother. Todashev "was living in Boston and I think he trained with him," Chapkhanov said.
Former roommate Khusen Taramov said the FBI was asking questions about a conversation Todashev had with the elder bombing suspect a month before the Boston Marathon attack.
The Tsarnaev brothers have roots in the turbulent Russian regions of Dagestan and Chechnya, which have become recruiting grounds for Islamic extremists. Investigators have said the brothers carried out the Boston bombing in retaliation for the U.S. wars in Muslim Iraq and Afghanistan.
Two law enforcement officials, speaking on condition of anonymity because they were not authorized to release details of the investigation, said Todashev came at the FBI agent with a knife before he was shot.
An FBI team was dispatched from Washington to review the shooting, a standard step in such cases.
Todashev was arrested earlier this month on a charge of aggravated battery after getting into a fight over a parking spot with two men ? a father and son ? at an Orlando shopping mall. The son was hospitalized with a split lip and several teeth knocked out, according to a sheriff's report. Todashev claimed self-defense.
"Also by his own admission Todashev was recently a former mixed martial arts fighter," the arresting deputy said in his report. "This skill puts his fighting ability way above that of a normal person."
Todashev was released on $3,500 bail after his May 4 arrest. His attorney, Alain Rivas, didn't immediately respond to a call for comment Wednesday.
Police tape blocked off the complex of townhouses near Universal Studios where Todashev was shot.

May 22, 2013 ? Researchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics and future "optoelectronic" circuits for sensors and information processing.
The electrode is made of silver nanowires covered with a material called graphene, an extremely thin layer of carbon. The hybrid material shows promise as a possible replacement for indium tin oxide, or ITO, used in transparent electrodes for touch-screen monitors, cell-phone displays and flat-screen televisions. Industry is seeking alternatives to ITO because of drawbacks: It is relatively expensive due to limited abundance of indium, and it is inflexible and degrades over time, becoming brittle and hindering performance.
"If you try to bend ITO it cracks and then stops functioning properly," said Purdue University doctoral student Suprem Das.
The hybrid material could represent a step toward innovations, including flexible solar cells and color monitors, flexible "heads-up" displays in car windshields and information displays on eyeglasses and visors.
"The key innovation is a material that is transparent, yet electrically conductive and flexible," said David Janes, a professor of electrical and computer engineering.
Research findings were detailed in a paper appearing online in April in the journal Advanced Functional Materials. It was authored by Das; visiting student Ruiyi Chen; graduate students Changwook Jeong and Mohammad Ryyan Khan; Janes and Muhammad A. Alam, a Purdue professor of electrical and computer engineering.
The hybrid concept was proposed in earlier publications by Purdue researchers, including a 2011 paper in the journal Nano Letters. The concept represents a general approach that could apply to many other materials, said Alam, who co-authored the Nano Letters paper.
"This is a beautiful illustration of how theory enables a fundamental new way to engineer material at the nanoscale and tailor its properties," he said.
Such hybrid structures could enable researchers to overcome the "electron-transport bottleneck" of extremely thin films, referred to as two-dimensional materials.
Combining graphene and silver nanowires in a hybrid material overcomes drawbacks of each material individually: the graphene and nanowires conduct electricity with too much resistance to be practical for transparent electrodes. Sheets of graphene are made of individual segments called grains, and resistance increases at the boundaries between these grains. Silver nanowires, on the other hand, have high resistance because they are randomly oriented like a jumble of toothpicks facing in different directions. This random orientation makes for poor contact between nanowires, resulting in high resistance.
"So neither is good for conducting electricity, but when you combine them in a hybrid structure, they are," Janes said.
The graphene is draped over the silver nanowires.
"It's like putting a sheet of cellophane over a bowl of noodles," Janes said. "The graphene wraps around the silver nanowires and stretches around them."
Findings show the material has a low "sheet resistance," or the electrical resistance in very thin layers of material, which is measured in units called "squares." At 22 ohms per square, it is five times better than ITO, which has a sheet resistance of 100 ohms per square.
Moreover, the hybrid structure was found to have little resistance change when bent, whereas ITO shows dramatic increases in resistance when bent.
"The generality of the theoretical concept underlying this experimental demonstration -- namely 'percolation-doping' -- suggests that it is likely to apply to a broad range of other 2-D nanocrystaline material, including graphene," Alam said.
A patent application has been filed by Purdue's Office of Technology Commercialization.

Rugged Galaxy S4 variant crops up once again in Croatia
Following yesterday's first photo appearance, today brings us a very quick video encounter with the Samsung Galaxy S4 Active. The ruggedized S4 variant, which sports physical buttons and a 1080p HD display, was captured in Croatia by an informant for MobileTechReview. The video mentions that it's powered by a Snapdragon S4 Plus CPU, however this is contradicted by earlier screenshots, which reveal a quad-core part at up to 1.9GHz with an Adreno 320 GPU. The S4 Plus line consists of dual-core Krait parts at up to 1.7GHz, so our money is still on a Snapdragon 600 being inside this thing. An 8 megapixel rear camera is also mentioned in the video, though this has yet to be confirmed.
The video is relatively short, but we can clearly see the latest version of Samsung's TouchWiz UI, and the "Active" seems just as snappy as its mainstream sibling. The footage appears to have been captured in the same demo station setting as yesterday's still images, and the weather widget shows Zagreb, Croatia as its location.
There's little doubt now that the Samsung Galaxy S4 Active is indeed a real device. We imagine it'll only be a matter of time before it's officially announced by the Korean manufacturer.

Preliminary balanced palinspastic reconstruction of Cenozoic deformation across the Himachal Himalaya (northwestern India)
A. Alexander G. Webb, Department of Geology and Geophysics, Louisiana State University, Baton Rouge, Louisiana 70803, USA. First published on 16 May 2013, http://dx.doi.org/10.1130/GES00787.1.
This study offers the first geometrically rigorous reconstruction of deformation in response to the India-Asia collision across a key portion of the western Himalaya. The reconstruction demonstrates the viability of important concepts pertaining to the dynamic evolution of crustal-scale contractional systems. First, despite variations in erosion and exhumation, the crystalline cores of mountain belts may be emplaced at depth. Second, zones of rapid uplift along the length of mountain belts in their interior may result from deep accretion and stacking of slices from the down-going collisional plate. Third, such stacking may occur in multiple systems at different crustal levels, all developing simultaneously. Finally, the reconstruction resolves much of the apparent mismatch between shortening estimates of two different types across the western Himalaya; i.e., between estimates based on reconstructing mountain belt deformation and estimates based on restoring plate motion using sea-floor magnetic anomalies.
Review and analysis of the age and origin of the Pliocene Bouse Formation, lower Colorado River Valley, southwestern USA
Jon E. Spencer et al., Arizona Geological Survey, 416 W. Congress Street, #100, Tucson, Arizona 85704, USA. First published on 16 May 2013, http://dx.doi.org/10.1130/GES00896.1. Issue: CRevolution 2: Origin and Evolution of the Colorado River System II.
The lower Pliocene Bouse Formation in the lower Colorado River Valley (southwestern USA) consists of basal marl and dense tufa overlain by siltstone and fine sandstone. It is locally overlain by and interbedded with sands derived from the Colorado River. Jon E. Spencer and colleagues briefly review 87Sr/86Sr analyses of Bouse carbonates and shells and carbonate and gypsum of similar age east of Las Vegas that indicate that all of these strata are isotopically similar to modern Colorado River water. They also review and add new data that are consistent with a step in Bouse Formation maximum elevations from 330 m south of Topock Gorge to 555 m to the north. New geochemical data from glass shards in a volcanic ash bed within the Bouse Formation, and from an ash bed within similar deposits in Bristol Basin west of the Colorado River Valley, indicate correlation of the two ash beds and coeval submergence of both areas. The tuff bed is identified as the 4.83 million year old Lawlor Tuff derived from the San Francisco Bay region. Spencer and colleagues conclude, as have some others, that the Bouse Formation was deposited in lakes produced by first-arriving Colorado River water that entered closed basins inherited from Basin and Range extension, and estimate that first arrival of river water occurred about 4.9 million years ago. If this interpretation is correct, addition of Bristol Basin to the Blythe Basin inundation area means that river discharge was sufficient to fill and spill a lake with an area of ~10,000 square kilometers. For spillover to occur, evaporation rates must have been significantly less in early Pliocene time than modern rates of about two to four meters per year, and/or Colorado River discharge was significantly greater than the current ~15 cubic kilometers per year. In this lacustrine interpretation, evaporation rates were sufficient to concentrate salts to levels that were hospitable to some marine organisms presumably introduced by birds.
Porosity and density of the AND-1B sediment core, McMurdo Sound region, Antarctica: Field consolidation enhanced by grounded ice
F. Niessen et al., Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Am Alten Hafen 26, 27568 Bremerhaven, Germany. First published on 7 May 2013, http://dx.doi.org/10.1130/GES00704.1. Issue: The ANDRILL McMurdo Ice Shelf (MIS) and Southern McMurdo Sound (SMS) Drilling Projects.
F. Niessen and colleagues present a study of density and porosity for the 1285-m-long AND-1B core recovered from a flexural moat in the McMurdo Sound (Antarctica) in order to interpret sediment consolidation in an ice-proximal location on the Antarctic shelf. Various lithologies imply environmental changes from open marine to subglacial, and are numerically expressed in high-resolution whole-core wet-bulk density (WBD). Grain density data interpolated from discrete samples range from 2.14 to 3.85 g/cm3 and are used to calculate porosity from WBD in order to avoid the 5% to 15% overestimation and underestimation of porosities obtained by standard methods. The trend of porosity extends from 0.5 near the top (Pleistocene) to 0.2 at the bottom (Miocene). Porosity fluctuations in different lithologies are superimposed with 0.2 to 0.3 in sequences younger than about one million years and 0.5 to 0.8 in Pliocene diatomites. The AND-1B porosities and void ratios of Pliocene diatomites and Pleistocene mudstones exhibit a large negative offset compared to modern lithological analogs and their consolidation trends. This offset cannot be explained in terms of the effective stress at the AND-1B site. The effective stress ranges from 0 to 4000 kPa in the upper 600 m, and reaches 13,000 kPa at the base of the AND-1B hole. Niessen and colleagues suggest that an excess of effective overburden stress of ~1700 and ~6000 kPa to explain porosities in Pliocene diatomites and Pleistocene mudstones, respectively. This is interpreted as glacial preconsolidation by subsequently grounded ice sheets under subpolar to polar, followed by colder polar types of glaciations. Information on Miocene consolidation is sparse due to alteration by diagenesis.
The Early Mesozoic Cordilleran arc and Late Triassic paleotopography: The detrital record in Upper Triassic sedimentary successions on and off the Colorado Plateau
N.R. Riggs et al., School of Earth Sciences and Environmental Sustainability, Northern Arizona University, Flagstaff, Arizona 86011, USA. First published on 7 May 2013, http://dx.doi.org/10.1130/GES00860.1.
A volcanic arc grew along the southwest coast of North America in Permian-Triassic time, between about 280 and 200 million years ago. One of the best ways to understand how this arc developed is to look at the sedimentary rocks that were deposited in river systems as it eroded, especially the durable grains that carry a record of the volcanic material that originally incorporated them. This paper by N.R. Riggs and colleagues provides results from a study of zircon grains from three Triassic sedimentary units, one each in northern and southern Arizona and one in eastern California, which together provide a Late Triassic snapshot of the rivers that drained off this volcanic arc. The chemical composition of the zircons can also be used to show how groups of the grains are likely related.
Late to post-Appalachian strain partitioning and extension in the Blue Ridge of Alabama and Georgia
Mark G. Steltenpohl et al., Dept. of Geology and Geography, Auburn University, Auburn, AL 36849, USA. First published on 7 May 2013, http://dx.doi.org/10.1130/GES00738.1.
Kinematic analysis of the Goodwater-Enitachopco and Alexander City faults document that dextral strains in the Alabama and western Georgia Blue Ridge are partitioned much farther toward the foreland than is reported to the northeast, likely as a consequence of the southern Appalachian master dcollement having passed obliquely across a several kilometer step up along the Cartersville transform. The top-to-the-south-southeast normal-slip component of movement along the Goodwater-Enitachopco fault is unusual, considering its position far toward the foreland. Loose timing constraints for this extensional event (late Carboniferous to Early Jurassic) leave room for several tectonic explanations, but Mark G. Steltenpohl and colleagues favor the following: (1) Late Pennsylvanian to Early Permian crustal thickening created a wedge of Blue Ridge rocks bound above by the Goodwater-Enitachopco, below by the dcollement, and to the northwest (present-day direction) by a topographically steep mountain front; (2) further convergence and crustal thickening caused this wedge to gravitationally collapse with southward-driven motion; and (3) Mesozoic rifting reactivated some of the faults as the Gulf of Mexico began to open.
Spatial and temporal trends in pre-caldera Jemez Mountains volcanic and fault activity
Shari A. Kelley et al., New Mexico Bureau of Geology and Mineral Resources, New Mexico Institute of Mining and Technology, 801 Leroy Place, Socorro, New Mexico 87801, USA. First published on 7 May 2013, http://dx.doi.org/10.1130/GES00897.1.
Nearly continuous eruption of lavas and tuffs over the last 10 Ma in the Jemez Mountains volcanic field (JMVF) on the western margin of the Rio Grande rift provide a unique opportunity to examine the interplay between faulting and volcanism along a rift margin. New 40Ar/39Ar dates on JMVF lavas and tuffs are coupled with the first comprehensive evaluation of the history of fault activity between 10 and 2 million years ago in this region to document a complex east to west to east pattern of faulting and volcanism through time in the northern JMVF. This pattern requires a reorientation of volcanic center alignment from a NE to a more northerly-striking trend, an episode of rift widening, and reactivation of previously unmapped Laramide structures. In addition, the new ages, combined with detailed mapping of both volcanic rocks and the Santa Fe Group, document significant pulses of faulting, erosion, and deposition during middle Miocene time and during late Miocene time along the Caones fault zone, a significant rift bounding structure that is exposed in the northern wall of the Valles caldera.

Riggs and colleagues provides results from a study of zircon grains from three Triassic sedimentary units, one each in northern and southern Arizona and one in eastern California, which together provide a Late Triassic snapshot of the rivers that drained off this volcanic arc. The chemical composition of the zircons can also be used to show how groups of the grains are likely related.
Late to post-Appalachian strain partitioning and extension in the Blue Ridge of Alabama and Georgia
Mark G. Steltenpohl et al., Dept. of Geology and Geography, Auburn University, Auburn, AL 36849, USA. First published on 7 May 2013, http://dx.doi.org/10.1130/GES00738.1.
Kinematic analysis of the Goodwater-Enitachopco and Alexander City faults document that dextral strains in the Alabama and western Georgia Blue Ridge are partitioned much farther toward the foreland than is reported to the northeast, likely as a consequence of the southern Appalachian master dcollement having passed obliquely across a several kilometer step up along the Cartersville transform. The top-to-the-south-southeast normal-slip component of movement along the Goodwater-Enitachopco fault is unusual, considering its position far toward the foreland. Loose timing constraints for this extensional event (late Carboniferous to Early Jurassic) leave room for several tectonic explanations, but Mark G. Steltenpohl and colleagues favor the following: (1) Late Pennsylvanian to Early Permian crustal thickening created a wedge of Blue Ridge rocks bound above by the Goodwater-Enitachopco, below by the dcollement, and to the northwest (present-day direction) by a topographically steep mountain front; (2) further convergence and crustal thickening caused this wedge to gravitationally collapse with southward-driven motion; and (3) Mesozoic rifting reactivated some of the faults as the Gulf of Mexico began to open.
Spatial and temporal trends in pre-caldera Jemez Mountains volcanic and fault activity
Shari A. Kelley et al., New Mexico Bureau of Geology and Mineral Resources, New Mexico Institute of Mining and Technology, 801 Leroy Place, Socorro, New Mexico 87801, USA. First published on 7 May 2013, http://dx.doi.org/10.1130/GES00897.1.
Nearly continuous eruption of lavas and tuffs over the last 10 Ma in the Jemez Mountains volcanic field (JMVF) on the western margin of the Rio Grande rift provide a unique opportunity to examine the interplay between faulting and volcanism along a rift margin. New 40Ar/39Ar dates on JMVF lavas and tuffs are coupled with the first comprehensive evaluation of the history of fault activity between 10 and 2 million years ago in this region to document a complex east to west to east pattern of faulting and volcanism through time in the northern JMVF. This pattern requires a reorientation of volcanic center alignment from a NE to a more northerly-striking trend, an episode of rift widening, and reactivation of previously unmapped Laramide structures. In addition, the new ages, combined with detailed mapping of both volcanic rocks and the Santa Fe Group, document significant pulses of faulting, erosion, and deposition during middle Miocene time and during late Miocene time along the Caones fault zone, a significant rift bounding structure that is exposed in the northern wall of the Valles caldera.

When Samsung unveiled its first 4K Ultra HD TV at CES this year, it said other sizes would follow, both larger and smaller than the initial 85-inch version. Now it's apparently ready to fulfill part of that promise, announcing in Korea that 65- and 55-inch models will launch next month. Of course our next question is how these smaller models will compare to the $39,999 MSRP 85S9 UHD TV in price. Hopefully they'll follow the path blazed by Sony, which recently introduced models at that size with pricing well below the $10,000 benchmark, although we expect Seiki's 50-incher will still hold the crown for value pricing. The press release mentions they will feature Samsung's upgradeable Smart TV platform and the "micro dimming ultimate" LED lighting of their larger cousin, but the odd "Timeless Gallery" frame / stand (pictured above on the 85-incher) was not listed.

EDMOND, Okla. (AP) ? A powerful storm system rumbled through the Plains and upper Midwest on Sunday, spawning tornadoes that damaged homes and buildings near Oklahoma City and put the Tulsa area on high-alert.
There were no immediate reports of injuries caused by any of the tornadoes that touched down in Oklahoma and Kansas, including one that hit the Oklahoma City suburb of Edmond before moving northeast toward Tulsa, 90 miles to the northeast.
For days, forecasters had been warning about the possibility of tornadoes from a weekend storm, and emergency responders as far north as Minnesota and as far south as Texas were keeping a close eye on the powerful system pushing eastward and northward through the nation's breadbasket.
"I knew it was coming," said Randy Grau, who huddled with his wife and two young boys in their Edmond's home's safe room when the tornado hit. He said he peered out his window as the weather worsened and believed he saw a flock of birds heading down the street.
"Then I realized it was swirling debris. That's when we shut the door of the safe room, said Grau, adding that they sheltered in the room for 10 minutes.
In Wichita, Kan., a tornado touched down near Mid-Content Airport on the city's southwest side shortly before 4 p.m., knocking out power to 7,500 homes and businesses but bypassing the most populated areas of Kansas' biggest city.
"At this point, there are very few reports of damage and no reports of fatalities or injuries, and we're very grateful for that," said Sedgwick County Emergency Management Director Randy Duncan.
In Oklahoma, aerial television news footage showed homes that appeared to have suffered significant damage northeast of Oklahoma City. Some outbuildings appeared to have been leveled, and some homes' roofs or walls had been knocked down.
"When I first drove into the neighborhood, I didn't see any major damage until I pulled into the front of my house," said Csabe Mathe, of Edmond, who found a part of his neighbor's fence in his swimming pool. "My reaction was: I hope insurance pays for the cleaning."
"I typically have two trash cans, and now I have five in my driveway."
The Storm Prediction Center had been warning about severe weather in the region since Wednesday, and on Friday, it zeroed in on Sunday as the day the storm system would likely pass through.
"They've been calling for this all day," Edmond resident Anita Wright said after riding out the twister in an underground shelter. She and her husband Ed emerged from their hiding place to find uprooted trees, downed limbs and damaged gutters in their home.
In Katie Leathers' backyard, the family's trampoline was tossed through a section of fence and a giant tree uprooted.
"I saw all the trees waving, and that's when I grabbed everyone and got into two closets," Leathers said. "All these trees just snapped."

SHAWNEE, Okla. (AP) ? Oklahoma's state medical examiner's office says a second person was killed by a tornado that leveled a central Oklahoma mobile home park.
Office spokeswoman Amy Elliot on Monday identified the two people who are confirmed to have been killed during Sunday's storms as 79-year-old Glen Irish and 76-year-old Billy Hutchinson. Both men were from Shawnee.
One of several tornadoes that touched down in parts of the nation's midsection on Sunday leveled the Steelman Estates Mobile Home Park near Shawnee.
It wasn't immediately clear if both victims lived at the mobile home park.
WASHINGTON (AP) ? Despite Democratic fears, predictions of the demise of President Barack Obama's agenda appear exaggerated after a week of cascading controversies, political triage by the administration and party leaders in Congress and lack of evidence to date of wrongdoing close to the Oval Office.
"Absolutely not," Steven Miller, the recently resigned acting head of the Internal Revenue Service, responded Friday when asked if he had any contact with the White House about targeting conservative groups seeking tax-exempt status for special treatment.
"The president's re-election campaign?" persisted Rep. Devin Nunes, R-Calif.
"No," said Miller.
The hearing took place at the end of a week in which Republicans repeatedly assailed Obama and were attacked by Democrats in turn ? yet sweeping immigration legislation advanced methodically toward bipartisan approval in the Senate Judiciary Committee. The measure "has strong support of its own in the Senate," said Sen. Amy Klobuchar, D-Minn., a member of the panel.
Across the Capitol, a bipartisan House group reported agreement in principle toward a compromise on the issue, which looms as Obama's best chance for a signature second-term domestic achievement. "I continue to believe that the House needs to deal with this," said House Speaker John Boehner, R-Ohio, who is not directly involved in the talks.
The president's nominee to become energy secretary, Ernest Moniz, won Senate confirmation, 97-0. And there were signs that Republicans might allow confirmation of Sri Srinivasan to the U.S. Court of Appeals for the District of Columbia Circuit, sometimes a stepping stone to the Supreme Court.
Separately, a House committee approved legislation to prevent a spike in interest rates on student loans on July 1. It moves in the direction of a White House-backed proposal for future rate changes to be based on private markets.
Even so, Rep. Fred Upton, R-Mich., chairman of the Energy and Commerce Committee, said, "It's been a bad week for the administration."
Several Democratic lawmakers and aides agreed and expressed concern about the impact on Obama's agenda ? even though much of it has been stymied by Republicans for months already.
At the same time, Rep. Dave Camp, R-Mich., voiced optimism that the IRS controversy would boost the push for an overhaul of the tax code, rather than derail it. "It may make a case for a simpler tax code, where the IRS has less discretion," he said.
Long-term budget issues, the main flash point of divided government since 2011, have receded as projected deficits fall in the wake of an improving economy and recently enacted spending cuts and tax increases.
Even before Obama began grappling with the IRS, the fallout from last year's deadly attack on the U.S. diplomatic mission in Benghazi, Libya, and from the Justice Department's secret seizure of Associated Press phone records, the two parties were at odds over steps to replace $85 billion in across-the-board spending cuts. In particular, Obama's call for higher taxes is a nonstarter with Republicans.
Other high-profile legislation and presidential appointees face difficulties that predate the current controversies.
Months ago, Obama scaled back requested gun safety legislation to center on expanded background checks for firearms purchasers. That was derailed in the Senate, has even less chance in the House and is unlikely to reach the president's desk.
Republicans oppose other recommendations from the president's State of the Union address, including automatic increases in the minimum wage, a pre-kindergarten program funded by higher cigarette taxes and more federal money for highways and bridge repair.
In a clash that long predates the IRS controversy, Senate Republicans seem intent on blocking Obama's nomination of Tom Perez as labor secretary. Gina McCarthy's nomination to head the Environmental Protection Agency is also on hold, at least temporarily, and Democrats expect Republican opposition awaits Penny Pritzker, Obama's choice for commerce secretary.
Rhetorically, the two parties fell into two camps when it came to the White House troubles. Democrats tended to describe them as controversies, Republicans often used less flattering terms.
Speaking on the Senate floor, Sen. Roger Wicker, R-Miss., accused the administration of fostering a "culture of intimidation." He referred to the IRS, the handling of the Benghazi attack and Health and Human Services Secretary Kathleen Sebelius' "fundraising among the industry people she regulates on behalf of the president's health care law."
Two days later, Camp, a 23-year veteran lawmaker, opened the IRS hearing by calling the agency's actions part of a "culture of cover-ups and intimidation in this administration." He offered no other examples.
Rep. Trey Radel, a first-term Florida Republican, said in an interview, "What we're looking at now is a breach of trust" from the White House.
House Democratic leader Nancy Pelosi of California offered a scathing response when asked if the controversies would hamper Obama's ability to win legislation from the Republican-controlled House. "Well, the last two years there was nothing that went through this Congress, and it was no AP, IRS or any other (thing) that we were dealing with."
"They just want to do nothing. And their timetable is never," she said of GOP lawmakers.
Similarly, Senate Majority Leader Harry Reid gave no ground on Benghazi, a dispute that increasingly centered on talking points written for administration officials to use on television after the attack last September in which U.S. Ambassador Chris Stevens and three other Americans were killed.
"It's obvious it's an attempt to embarrass President Obama and embarrass Hillary Clinton," he said of Republican criticism that first flared during last year's election campaign.
On a third front, Sen. Chuck Schumer, D-N.Y., resurrected legislation that would requiring a judge to approve subpoenas for news media communications records when investigating news leaks said to threaten the national security. It was a response to the FBI's secret, successful pursuit of Associated Press phone records in a current probe.
While Democrats counterattacked on Benghazi and parried on leaks, they bashed the IRS' treatment of conservative groups as improper if not illegal ? and warned Republicans not to overplay their hand.

IRVING, Texas (AP) ? Ken Venturi was a 14-year-old with a camera trying to get a picture of Byron Nelson when he first met the golfer who would become a mentor and dear friend.
"He was, like, getting under the ropes a little bit, " Nelson's widow, Peggy, recalled Saturday of that moment during the 1946 San Francisco Open. "Byron said, 'Kid, could you move back under the ropes a little ways?' And Ken goes home and tells his mom, I met the greatest man today, Byron Nelson, and he spoke to me."
Venturi died Friday, in the middle of tournament week for the Byron Nelson Championship.
Venturi overcame dehydration to win the 1964 U.S. Open and spent 35 years in the booth for CBS Sports. He died at age 82, 11 days after being inducted into the World Golf Hall of Fame.
When CBS came on the air Saturday for third-round coverage of the Nelson, the first 15 minutes of the broadcast were a tribute to Venturi, who retired as the network's lead golf analyst in 2002.
Jim Nantz, whose 54th birthday was on the same day his longtime partner and friend died, said it was "not going to be easy" to broadcast this weekend.
The death of Venturi came a month and a day after broadcaster Pat Summerall died, also at age 82.
"It's been an unbelievable month to lose guys like that," said Lance Barrow, the longtime CBS producer for golf and NFL broadcasts. "It's a sad day."
Barrow likened Venturi's lengthy career as a broadcaster to Nelson's surely unmatchable record of 11 consecutive tournaments won.
"There will be no one ever in sports television again that will have the run that Ken Venturi had," Barrow said. "And will not come close to it, as an analyst in any sport, much less golf."
Tiger Woods issued a statement Saturday saying that Venturi's recent Hall of Fame induction was a "fitting tribute to a special person in our game."
"He was a good man and the voice of golf for so many years," said Woods, who isn't playing the Nelson this week. "He will be remembered for what he did on the golf course and for his personality in the broadcast booth. "
Ten years after Venturi was trying to get a picture of Nelson, he was a top amateur teamed with Harvie Ward against Nelson and Ben Hogan in what has since become known as "The Match."
Peggy Nelson said that was an amazing day for the players, and that Byron Nelson, who died in 2006 at age 94, and Venturi would sometimes talk about different shots each of them hit that day.
She characterized their friendship as precious and talked about what it was like "to see Byron's face light up whenever he thought of him" or when Venturi would call.
"I think that if Byron could have, he would have adopted Kenny," Peggy Nelson said. "Kenny's values were so strong and so wanting to help people as much as he could, because he knew that he was a very blessed man in the game of golf and that he was blessed to have so many friends like Byron and Mr. Hogan, and being close to both of them."
Barrow said Venturi tried to do everything Nelson taught him, from never charging for a golf lesson "because Byron Nelson said don't do that" to also checking in with the pro shop at a golf course before playing a round.
"This was a great thing that Byron Nelson told him, always go in and ask the pro who holds the course record. And if it's a pro, don't ever break it because that pro is there every day. You're only there for a few days," Barrow said. "That's what Venturi was like."
May 18, 2013 ? In order to avoid harms associated with alcohol consumption, in 2009 the National Institute on Alcohol Abuse and Alcoholism issued guidelines that define low-risk drinking. These guidelines differ for men and women: no more than four drinks per day, and 14 drinks per week for men, and no more than three drinks per day, and seven drinks per week for women. A study of how well college students adhere to these limits has found that female college student drinkers exceed national drinking guidelines for weekly drinking more frequently than their male counterparts.
Results will be published in the October 2013 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.
"Recommended drinking limits are lower for women than for men because research to date has found that women experience alcohol-related problems at lower levels of alcohol consumption than men," explained Bettina B. Hoeppner of the Massachusetts General Hospital Center for Addiction Medicine, an assistant professor of psychology at Harvard Medical School as well as corresponding author for the study.
"It is always important to take gender into account when studying health or risk behaviors," added Melissa A. Lewis, associate professor in the department of psychiatry and behavioral sciences at the University of Washington. "Even if you hold weight constant, there are differences in terms of how alcohol affects men and women. For example, men have more of an enzyme in the stomach -- a gastric alcohol dehydrogenase -- that lowers the amount of alcohol that makes it into the bloodstream. Also, women have less blood going through the bloodstream than a man at the same weight, so alcohol gets more concentrated in the bloodstream."
For this study, Hoeppner and her colleagues asked 992 college students (575 females, 417 males) to report their daily drinking habits on a biweekly basis, using web-based surveys throughout their first year of college.
"We found that female college-student drinkers exceeded national drinking guidelines for weekly drinking more frequently than their male counterparts," said Hoeppner. "Weekly cut-offs are recommended to prevent long-term harmful effects due to alcohol, such as liver disease and breast cancer. By exceeding weekly limits more often than men, women are putting themselves at increased risk for experiencing such long-term effects."
"In addition," said Lewis, "men's weekly drinking declined over time whereas women's weekly drinking did not. This finding is concerning. If women continue to exceed weekly drinking recommendations over time, it puts them at greater risk for health issues, such as liver or heart disease and certain forms of cancer."
"These findings contribute to our understanding of how populations adhere to national drinking guidelines," said Hoeppner. "Specifically, it examines college student drinkers, where adherence to weekly drinking limits has not been examined before. Generally, 'binge drinking' receives more attention when examining college student drinking, however, for long-term health, it is also important to examine the establishment of drinking patterns that may lead to long-term harmful effects, not just short-term effects."
"These findings highlight the need for prevention efforts to focus on both daily and weekly limits to reduce harm from short- and long-term negative consequences related to alcohol use," said Lewis. "Current preventative interventions often do not focus on weekly drinking recommendations, which is important and a warranted area of future research.
Hoeppner agreed. "Our results might motivate clinicians to address weekly drinking limits and the potential for long-term alcohol related harm with their patients," she said. "The reasons that many college students exceed these weekly limits are unclear. It is possible that lack of awareness of the guidelines and possible consequences of exceeding them contributes to these high rates. If so, clinicians might reduce harm by educating their college-student patients about the guidelines and the harm they seek to prevent, especially their female patients. Similarly, researchers and clinicians designing prevention/intervention programs might find it useful to address weekly drinking limits in their programs, both to reduce incidence rates thereof, and to identify the reasons for exceeding these guidelines."
