NASA JPL controls rover with Leap Motion, shows faith in consumer hardware (video)

If you think using the Leap Motion controller for playing air guitar and typing without a keyboard was cool, try using it to control a NASA rover. Victor Luo and Jeff Norris from NASA's Jet Propulsion Lab got on stage at the Game Developers Conference here in San Francisco to do just that with the ATHLETE (All-Terrain Hex-Limbed Extra-Terrestrial Explorer), which was located 383 miles away in Pasadena. As Luo waved his hand over the sensor, the robot moved in kind, reacting to the subtle movements of his fingers and wrists, wowing the crowd that watched it over a projected Google+ Hangout.

We spoke with Luo and Norris after the panel to gain further insight into the project. As Luo explains, one of JPL's main goals is to build tools to control robots needed for space exploration. Seeing as the gaming industry is already rife with user-friendly controllers ripe for the plucking, it made sense to harness them for the job. "We're very used to the bleeding edge," he said. "From the Kinect to the PlayStation Move, they represent major investments into usability." Hit the jump for our impressions of the simulation software, a look at JPL's grander goal and for video clips of the demo and panel itself.

UCLA hires Steve Alford as new basketball coach

LOS ANGELES (AP) ? Steve Alford was hired as UCLA basketball coach on Saturday, spurning New Mexico days after he agreed to a new 10-year deal with the Lobos for a chance to run what he called "the premier basketball program in the country."

The Bruins are bringing in someone who shares the same Indiana roots as John Wooden, who led UCLA to a record 10 national championships, including seven in a row, before retiring in 1975. Alford learned about Wooden as a first-grader in Martinsville, Ind., where his father, Sam, coached the high school basketball team at Wooden's alma mater.

"Ever since then there was a draw to find out more about him," Alford said on a teleconference. "I know my first steps into Pauley I will really feel that."

Alford agreed to a seven-year deal worth $18.2 million, with a yearly salary of $2.6 million and a $200,000 signing bonus, according to UCLA athletic director Dan Guerrero.

Alford will be introduced in Westwood on Tuesday.

"This is truly a leap of faith," he said.

Guerrero said UCLA reached out to Alford first, not knowing whether he would be interested in the Bruins. Once he confirmed he was, the details were finalized early Saturday, Guerrero said.

"It was not an easy decision because I was extremely happy," Alford said. "I was about as happy as I can be.

"When I kept thinking about things, it still came back to UCLA. You're talking about the premier basketball program in the country. To have an opportunity like this, they don't come around every day."

Guerrero said Alford is "the perfect fit for UCLA" because he connects with a new generation of players and brings an up-tempo and team-oriented style of play to Westwood.

"He's ready for this stage," Guerrero said.

Alford's deal with New Mexico, scheduled to take effect on April 1, was worth more than $20 million over 10 years.

Guerrero said Alford is responsible for a buyout of his agreement in Albuquerque, but that UCLA would work out the details. Both Alford and New Mexico athletic director Paul Krebs said they didn't know how much the buyout was worth.

Alford, who is 48, succeeds Ben Howland, who was fired last weekend after 10 years and a 233-107 record that included three consecutive Final Four appearances and four Pac-12 titles. The Bruins were 25-10 this season, which ended with a 20-point loss to Minnesota in the second round of the NCAA tournament.

Alford led New Mexico to a 29-6 record this season that included the Mountain West regular-season and tournament titles. But the Lobos were upset by Harvard in the second round of the NCAAs shortly after Alford's new contract had been announced.

Alford had a 155-52 record in six years at New Mexico, with the Lobos making three trips to the NCAA tournament. He was selected Mountain West coach of the year three times.

"I'm about building programs, not teams, not seasons," Alford said. "UCLA doesn't just want one winning season, UCLA wants a basketball program that is going to breed consistent excellence.

"I've always tried to do things with excellence. When you think of UCLA in every regard, you see the word excellence."

Expectations have always been high in Westwood since Wooden's era. The Bruins own a record 11 national championships, but have won just one ? in 1995 under Jim Harrick ? since Wooden retired.

"Nobody understands pressure any more than I do. I've been under pressure since I was 16," said Alford, whose high school gym in New Castle, Ind., seats 10,000 and frequently sold out when he was there. "You're not going to find anybody more competitive than I am."

Guerrero said, "He's not the kind of guy that will shy away from what UCLA basketball is all about."

The Lobos didn't just lose Alford, they also won't have his son, Bryce, on their roster next season. Alford said his highly touted son would follow him to Westwood, continuing a tradition that Alford first established when he played under his father at New Castle Chrysler High.

Krebs said it was clear when he talked to Alford on Saturday morning that his mind was made up, and although he's disappointed, he said he respected the decision.

Krebs said it was like a "bomb dropped in the room" when Alford told his players he was leaving.

"This is a very emotional time," Krebs said. "There is no good way to break the news to the young men in the program. ... There's a lot of raw emotion right now."

Alford said, "That's not easy to look those young men in the face, but I think they understand. The reason they understand is it's UCLA. If it was anywhere else, this is not a decision that would have been made."

Lobos senior center Alex Kirk said, "Nobody would say no to UCLA. That's crazy."

Guerrero had said he wanted a coach who would help boost season ticket sales. The Bruins had just a few sellouts at newly renovated Pauley Pavilion this season.

"I think the UCLA family will embrace him. I think he'll be able to hit on all cylinders," Guerrero said. "He'll be able to energize the fan base in so many ways. Look at New Mexico, they get 15,000 a game. It's madness there."

Alford is known for his up-tempo coaching style, which should suit Bruins fans turned off by Howland's grind-it-out defensive emphasis.

"We do like to score points, we like transition, we like to get up and down the floor," he said, while noting that defense wins championships. "Ultimately, it's about the product ? are they good young men of character and integrity?"

Alford called recruiting in fertile Southern California "of the utmost importance." He had players from the region on his New Mexico roster, including Kendall Williams, who became Mountain West player of the year.

"I will hit the ground running," he said, noting the respect he has for high school coaches was formed through his father.

Alford's other head coaching stints were at Iowa (2000-07), Missouri State (1996-99) and Manchester College (1992-95) in Indiana.

Alford is famous in the Hoosier state, where he starred at Indiana University from 1984-87 under coach Bob Knight. The Hoosiers won the national championship in his senior year. He also played on the gold medal-winning 1984 U.S. Olympic basketball team in Los Angeles as a college sophomore. Knight coached that team. Alford said he put in a call to his former coach about taking the UCLA job.

Alford was drafted by the Dallas Mavericks in 1987 and played four years in the NBA before starting his head coaching career at tiny Division III Manchester.

As a high school senior, Alford averaged 37.7 points and was Indiana Mr. Basketball.

Besides Bryce, Alford and his wife, Tanya, have a son, Kory, and a daughter, Kayla.

KAUFMAN, Texas (AP) ? Kaufman County District Attorney Mike McLelland took no chances after one of his assistant prosecutors was assassinated two months ago. McLelland said he carried a gun everywhere he went and took extra care when answering the door at his home.

"I'm ahead of everybody else because, basically, I'm a soldier," the 23-year Army veteran boasted in an interview less than two weeks ago.

On Saturday, he and his wife were found dead in their home just outside the town of Forney, about 20 miles from Dallas, killed in an attack for which authorities have given no motive.

"Everybody's a little on edge and a little shocked," Forney Mayor Darren Rozell said. "It appears this was not a random act."

The killings came less than two weeks after Colorado's prison chief was gunned down at his front door by a white-supremacist ex-convict, and two months after Kaufman County Assistant District Attorney Mark Hasse was shot to death in a parking lot a block from his office Jan. 31. No arrests have been made in Hasse's slaying.

Kaufman County Sheriff David Byrnes confirmed Sunday that the McLellands had been shot. As for whether their deaths were related to Hasse's slaying, Byrnes said there was nothing to indicate that "for sure," but declined to discuss it further during a news conference.

McLelland himself, in an Associated Press interview, raised the possibility that Hasse was gunned down by a white supremacist gang. McLelland, elected DA in 2010, said that Hasse hadn't prosecuted any cases against white supremacists but that his office had handled several, and those gangs had a strong presence in the area.

"We put some real dents in the Aryan Brotherhood around here in the past year," McLelland said after Colorado's corrections director, Tom Clements, was shot to death March 19 when he answered the doorbell.

Kaufman Police Chief Chris Aulbaugh said recently the FBI was checking to see if Hasse's killing could be related to Clements'. Evan Spencer Ebel, a former Colorado inmate and white supremacist who authorities believe killed Clements, died in a March 21 shootout with Texas deputies about 100 miles from Kaufman.

McLelland, 63, said after Hasse's slaying that he carried a gun everywhere he went, even to walk his dog. He figured that was where assassins were more likely to try to get him. He said he had warned all his employees to be constantly on the alert.

"The people in my line of work are going to have to get better at it," he said of the danger, "because they're going to need it more in the future."

The number of attacks on prosecutors, judges and senior law enforcement officers in the U.S. has spiked in the past three years, according to Glenn McGovern, an investigator with the Santa Clara County, Calif., District Attorney's Office who tracks such cases.

But they're still rare. McLelland is the 13th prosecutor in the U.S. that the National Association of District Attorneys has recorded killed since the organization began keeping track in the 1960s.

For about a month after Hasse's slaying, sheriff's deputies were parked in the district attorney's driveway, said Sam Rosander, a McLelland neighbor.

The FBI and the Texas Rangers joined the investigation into the McLellands' deaths.

McLelland and his wife, Cynthia, were the parents of two daughters and three sons. One son is a police officer in Dallas. The couple had moved into the home a few years ago, Rozell said.

"Real friendly, became part of our community quickly," Rozell said. "They were a really pleasant happy couple."

Kan. gov says his sales tax plan fits with budget

TOPEKA, Kan. (AP) -- Gov. Sam Brownback said Thursday that Kansas' "budget reality" will push lawmakers toward approving his proposal to cancel a scheduled decrease in the state sales tax.

The Republican governor said he'll consider "anybody's proposal" as the GOP-dominated House and Senate negotiate the final version of tax legislation. But Brownback also said legislators have limited options for stabilizing the budget while seeking further cuts in individual income taxes.

Brownback and most Republican legislators want to follow up on massive income tax cuts enacted last year with another round of reductions in personal income tax rates. Last year's cuts created a budget shortfall, and Brownback has promised to protect important programs such as education funding and social services.

Meanwhile, the state's 6.3 percent sales tax is scheduled by law to drop to 5.7 percent in July, the result of a budget-balancing agreement in 2010 that temporarily boosted the tax to its current level. Legislators in both parties don't want to break the pledge, but some are willing to do it with the promise of future income tax cuts.

"There's just the budget reality," Brownback said. "I think it's coming across to people that you've got to get your resource package somewhere. The budget doesn't work without the tax piece of it."

The Senate approved tax legislation embracing Brownback's proposals to keep the sales tax at its current rate while guaranteeing cuts in individual income tax rates over the next four years. The top rate would drop for 2017 to 3.5 percent from 4.9 percent.

The House passed a tax plan that allows the sales to drop and cuts income tax rates less aggressively. The House plan would decrease personal income tax rates each year if overall state revenues grew more than 2 percent. The top rate for 2017 would be 4.88 percent, according to legislative researchers.

Three senators and three House members are negotiating tax issues. They planned to resume talks Monday, when lawmakers return from a long weekend for a five-day push to finish most of the year's business.

House GOP leaders contend a proposal to keep the sales tax at its current rate can't pass their 125-member chamber.

"The governor couldn't convince me to do it, and I've been pretty good about voting with the governor on stuff," said Rep. Scott Schwab, an Olathe Republican and one of the tax negotiators. "I don't know how you get there. I'm not sure he's got 20 votes."

Critics of Brownback's push toward phasing out personal income taxes note it would force the state to rely most heavily on its sales tax to finance government. Poor families tend to pay a higher percentage of their incomes to that tax than do wealthy ones.

The governor and many GOP lawmakers argue that phasing out personal income taxes will help all taxpayers by boosting the economy and creating jobs. Schwab said Brownback should trust that last year's cuts ? worth nearly $850 million during the fiscal year beginning in July ? already will boost the economy enough for the House plan to provide sufficient, future reductions in income tax rates.

Also, Schwab noted that the House and Senate are negotiating the final version of a proposed $14.5 billion budget after making significant changes from Brownback's spending proposals.

"The governor needs to understand that his budget has been altered by both chambers," Schwab said. "I don't think we need to raise taxes to pay for his budget if we're not going to pass his budget."

A key difference between the governor and legislators concerns higher education spending. Brownback proposed flat spending on universities, community colleges and technical colleges flat, while both chambers are seeking cuts.

"We're going to fight for our budget," Brownback told reporters. "You're going to need to collect revenue to run the state somewhere."

Estrogen plus progestin use linked with increased breast cancer incidence and mortality

Mar. 29, 2013 ? Estrogen plus progestin use is linked with increased breast cancer incidence. In addition, prognosis is similar for both users and nonusers of combined hormone therapy, suggesting that mortality from breast cancer may be higher for hormone therapy users as well, according to a study published March 29 in the Journal of the National Cancer Institute.

In the Women's Health Initiative (WHI) randomized trial, estrogen plus progestin was associated with an increase in both breast cancer incidence and mortality. However, most observational studies have linked estrogen plus progestin with more positive outcomes.

In order to determine the differences between the WHI trial and other observational studies, Rowan T. Chlebowski, M.D., Ph.D., Los Angeles Biomedical Research Institute (LA BioMed) lead researcher and colleagues, looked at postmenopausal women with no prior hysterectomy with negative mammograms within two years who were either users or non-users of estrogen and progestin combined therapy.

The researchers found that breast cancer incidence was higher in estrogen plus progestin users than incidence in nonusers. Women who started hormone therapy closer to menopause had a higher breast cancer risk with a weakening influence as the time from menopause increased.

"Because survival after breast cancer diagnosis did not differ between estrogen plus progestin users and nonusers, the higher breast cancer incidence of those using estrogen plus progestin may lead to increased breast cancer mortality on a population basis," the authors write.

In an accompanying editorial, Catherine Schairer, Ph.D., and Louise A. Brinton, Ph.D., both of the National Cancer Institute, write that questions remain about whether the data analyzed from the WHI observational study resolves the differences in tumor prognosis and tumor characteristics when compared to the WHI randomized trial. They write that, "In general, tumors in estrogen plus progestin users in the WHI Observational Study were not significantly different from those in non-hormone users with regard to number of positive lymph nodes or tumor size, but were more likely to be well differentiated and positive for hormone receptors, findings which are similar to other observational studies." This, however, did not translate into a survival benefit. They recommend further analyses in this and other datasets of currency and duration of hormone use in relationship to tumor development to fully resolve the issue of tumor characteristics associated with estrogen plus progestin therapy.

New York's First Occupied Shipping Container Home | Inthralld

Shipping Containers are of course a popular building material in this day and age, where people are more green and planning on being more sustainable for the earth. While a majority of what we see as far as homes are concerned are all over the world? New York is a relatively surprising location for such a structure.

The first shipping container home in New York is now occupied by its owners after a myriad of issues and construction restrictions? 5 years after purchasing the plot. The home is equipped with radiant heated flooring, and Super Therm insulation for the colder weather months.

Though there has been much criticism to the overall architecture, interior design and ultimate outcome of the space, the owners have overcome a great feat in dealing with their building restrictions and other issues along the way. There?s always room for improvement, and this home will surely pave the way for other NY based shipping container homes.

Thousands of Amazon S3 data stores left unsecured due to misconfiguration

Will Vandevanter, of Help Net Security, made a rather disturbing discovery: thousands of Amazon S3 data "buckets" were improperly configured and left exposed to prying eyes. Vandevanter started his probe by generating URLs using the names of major companies and sites that use Amazon's cloud storage service. In the end he uncovered 12,328 of the so-called buckets -- 1,951 of which were visible to the public. Those folders were home to some 126 billion files that contain everything from personal data hosted by a social networking service, sales records, video game source code and even unencrypted backups of databases. By default, S3 accounts are set to private, which means these stores of potentially sensitive data had to be flipped to public manually -- most likely by accident. Amazon has responded to the discovery by alerting users who might have inadvertently made their files publicly accessible. If you've got an S3 account of your own, now would be an excellent time to double check your own settings. And if you're looking for more details of Vandevanter's research, hit up the source link.

Proximity to coal-tar-sealed pavement raises risk of cancer, study finds

Mar. 28, 2013 ? People living near asphalt pavement sealed with coal tar have an elevated risk of cancer, according to a study in the journal Environmental Science and Technology. Much of this calculated excess risk results from exposures in children, age six or younger, to polycyclic aromatic hydrocarbons (PAHs) from the sealant.

"The increased cancer risk associated with coal-tar-sealed asphalt (CSA) likely affects a large number of people in the U.S. Our results indicate that the presence of coal-tar-based pavement sealants is associated with significant increases in estimated excess lifetime cancer risk for nearby residents," said E. Spencer Williams, Ph.D., principal author of the study and Baylor University assistant research scientist at the Center for Reservoir and Aquatic Systems Research in Baylor's College of Arts & Sciences.

Researchers from Baylor University in Waco, Texas, and the in Austin, Texas, are the first to report on the potential human health effects of PAHs in settled house dust and soil in living spaces and soil adjacent to parking lots sealed with coal-tar-based products.

"Exposure to these compounds in settled house dust is a particularly important source of risk for children younger than six years of age, as they are expected to ingest this material at higher rates," Williams said. "This indicates that the use of coal-tar-based pavement sealants magnifies aggregate exposures to PAHs in children and adults in residences adjacent to where these products are used and is associated with human health risks in excess of widely accepted standards."

Data on PAHs in settled house dust used for this analysis were published previously by the same authors. In that study, settled house dust and parking lot dust were sampled for 23 ground-floor apartments in Austin, Texas. The parking lot surfaces adjacent to the apartments were coal-tar-sealed asphalt, asphalt-based sealant over asphalt pavement, or unsealed concrete. Concentrations of PAHs were 25 times higher in house dust in residences adjacent to coal-tar-sealed pavement compared to those with other pavement types. "This study was the first to find a strong association between a product or a behavior and PAHs in house dust," said Barbara Mahler, the USGS research hydrologist who oversaw the study.

For this study, doses and risk associated with residences adjacent to unsealed asphalt lots were considered relative to those adjacent to (CSA) parking lots. Benzo(a)pyrene concentrations in CSA-affected settled house dust were high relative to those reported in most parts of the U.S. where coal-tar-based sealcoat is not used (California and Arizona). Data for PAHs in coal-tar-sealed asphalt-affected soils and unsealed asphalt-affected soils are available from samples from New Hampshire and suburban Chicago.

The analysis did not consider exposure to the dust on the pavement itself, which has PAH concentrations 10s to 100s of times higher than those in house dust or soil, or inhalation of air over sealed pavement. "Over time, about half of the PAHs in the sealcoat are released into the air, and concentrations in air are extremely high, particularly in the hours to days after application," said Peter Van Metre, USGS research hydrologist and author of two papers on volatilization of PAHs from sealcoat.

Sealcoat is a black, shiny substance sprayed or painted on the asphalt pavement of parking lots, driveways, and playgrounds to improve appearance and protect the underlying asphalt. An estimated 85 million gallons of coal-tar-based sealant are applied to pavement each year, primarily east of the Continental Divide in the U.S. and parts of Canada. Coal-tar-based pavement sealants are 15 to 35 percent coal-tar pitch, which has been classified as a human carcinogen by the International Agency for Research on Cancer. Over time, the dried sealant is worn away from pavement surfaces, and the resulting mobile dust particles can be transported into nearby homes.

"Although the analysis presented here is based on a limited dataset, the results indicate that biomonitoring might be warranted to characterize the exposure of children and adults to PAHs associated with coal-tar-based pavement sealant," Williams said. "Further investigation is also needed into the impacts of coal-tar-based pavement sealants on PAH concentrations in indoor and outdoor environments."

Samsung Galaxy S 4 hits the FCC in MetroPCS and Sprint forms

Get ready for a small deluge of Galaxy S 4 filings at the FCC in the near future. Just a couple of weeks after Samsung's flagship hit the US agency in its international guise, we're now seeing the first US editions of the smartphone receive approval, starting with both MetroPCS (SCH-R970) and Sprint (SPH-L720) examples. Either has CDMA, EV-DO and LTE, although there's variances you'll want to watch for if you're free to choose between carriers: the Sprint version has HSPA 3G for world roaming, while the MetroPCS model drops HSPA but has a broad four bands of LTE meant mostly to support other mid-size American networks, like US Cellular. We still have AT&T, T-Mobile and Verizon to go among the bigger US providers supporting the GS4, although it's just a matter of time before their models make FCC appearances.

Father cleaning shotgun shoots 10-year-old son in the head in N.C.

By NBC News staff

A father who was cleaning his shotgun accidentally shot his 10-year-old son to death at their home in North Carolina.

Christopher Stanlane was wiping the gun down Sunday afternoon when he shot the boy in the head, Capt. Anthony Thompson of the Robeson County Sheriff?s Office told NBC affiliate WMBF.

Stanlane dropped his gun and rushed his 8-year-old daughter to another room while his wife called 911.

The son, Christopher Jr., was pronounced dead by paramedics at the house in the town of Fairmont.

?Most people think that guns are what kill people, and it?s not,? said Sgt. Eric Gavaghan, another county sheriff?s official, who teaches gun safety classes. ?The people and their inexperience, their lack of training, that?s what hurts other people with firearms.?

Normal brain activity linked to DNA damage

msnbc.com

By Charles Choi
LiveScience

Brain activity from experiences as common as exploring new locations surprisingly damages the noggin's DNA, hinting that such disruptions may be a key part of thinking, learning and memory, researchers say.

This damage normally heals rapidly, but abnormal proteins seen in Alzheimer's disease can increase this damage further, perhaps overwhelming the ability of brain cells to heal it. Further research into preventing this damage might help treat brain disorders, scientists added.

Explorer mice
Scientists analyzed young adult mice after they were placed into new, larger cages with different toys and odors that they were allowed to explore for two hours. They measured brain levels of a protein known as gamma-H2A.X, which accumulates when breaks occur in double-stranded molecules of DNA.

"DNA comes in double strands, and has the shape of a twisted ladder," said researcher Lennart Mucke, a neurologist and neuroscientist at the Gladstone Institute of Neurological Disease and the University of California at San Francisco. "Breaks in one strand, in one rail of the ladder, occur quite frequently, but breaking both takes quite a bit of damage and, in the brain, was thought to happen mostly in the context of disease." [10 Odd Facts About the Brain]

Unexpectedly, the researchers found such breaks also happened in the neurons of perfectly healthy mice, with up to six times more breaks in the neurons of explorer mice than in mice that remained in their home cages.

"Breaks of double strands of DNA seem to be a part of normal healthy brain activity," Mucke told LiveScience.

These DNA breaks occurred in various brain regions, especially in the dentate gyrus, an area necessary for spatial memory.

"It is both novel and intriguing, (the) team's finding that the accumulation and repair of DSBs (double-strand breaks) may be part of normal learning," said neuroscientist Fred Gage, of the Salk Institute, who did not take part in this study.

Mystery of DNA breaks
It remains uncertain why brain activity causes DNA breaks. Active neurons do generate DNA-damaging chemicals such as free radicals, but neurons in lab dishes did not have significantly fewer breaks when given antioxidant molecules that counteract free radicals.

Instead, the researchers suggest these breaks could actually help with the genetic activity linked with mental activity.

"We are now very excited to explore why neuron activity causes these breaks in DNA?? whether these breaks somehow facilitate the rapid conversion of genes into proteins involved in memory and learning and in processing all the information you take in when you do something new," Mucke said.

Many of the DNA breaks were fixed within 24 hours via DNA repair mechanisms in the cells. However, mice genetically engineered to produce a protein fragment known as amyloid beta, which accumulates in the brains of Alzheimer's patients, had more DNA breaks than normal in their brains, a problem that worsened during exploration.

Mice that produce human amyloid beta in their brains often have abnormal brain activity, including epileptic seizures, which can also occur in Alzheimer's patients. The researchers found that blocking this abnormal brain activity with the widely used anti-epileptic drug levetiracetam reduced the number of DNA breaks in the neurons of these mice.

"Levetiracetam is already an FDA-approved drug, and a very small clinical trial has already shown that it could provide some benefits in people with early-stage Alzheimer's," Mucke said. "These findings support the idea that the drug might be able to modify the disease by preventing the accumulation of DNA breaks that may promote its progress."

"We're in the process now of designing a larger-scale carefully controlled clinical trial to see if such a strategy is of benefit," Mucke added. "We encourage people to wait until this data becomes available and not jump the gun and start taking this drug when it hasn't been validated thoroughly yet."

The scientists also found that when mice lacked a protein known as tau, excess amyloid beta no longer caused more DNA breaks.

"Tau is intimately involved with Alzheimer's ? it seems to cooperate with amyloid beta," Mucke said. "In the absence of tau, amyloid beta doesn't seem to elicit detrimental effects. We're in the process of developing strategies to manipulate tau in Alzheimer's, and these findings encourage us to intensify and accelerate these efforts."

The scientists detailed their findings online Sunday in the journal Nature Neuroscience.

Pastor Asks Council to Allow Guns In Church

WILLISTON, N.D. (AP) - Some pastors in a northwestern North Dakota city are asking that guns be allowed in churches.
?? ?
The Forum newspaper reports that the group plans to submit a petition this week to Williston city commissioners that would give churches the option of allowing concealed weapons.
?? ?
The Rev. Will Page, associate professor of Cornerstone Baptist Church, says he's worried that people with evil intentions may target churches because they know members of the congregation are not armed.
?? ?
The group says the petition is motivated by mass shootings elsewhere and not the state's oil boom.
?? ?
The state Legislature is considering allowing guns in churches and other places.
?? ?
Sen. Stan Lyson, of Williston, a former Williams County sheriff, says he doesn't believe that allowing concealed weapons in church or other places improves safety.

Hand surgery enhances life quality for those with spinal cord injuries

Reconstructive hand surgery can dramatically enhance the life quality and independence of those paralysed by a cervical spinal cord injury. Despite this, the operation is not frequently performed, either in Sweden or elsewhere. Researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden are now hoping to change that.

A cervical spinal cord injury entails paralysis in both arms and legs, severely limiting daily life for its victims. Previous studies have shown that the capability that those with cervical spinal cord injuries most wish to recover is a functioning hand.

At the Sahlgrenska University Hospital, since the 1970's, it has been possible to improve the gripping ability for these individuals by surgical means, and at present an estimated 40 per cent of all spinal cord injury patients in Sweden undergo this operation.

The PhD student Johanna Wangdell, who also works as an occupational therapist, has in the course of her thesis interviewed (all those) patients who have had their hand function reconstructed at the Sahlgrenska University Hospital since 2003.

The thesis shows that this hand surgery, in a dramatic way, enhances the life quality of those with spinal cord injuries:

"The surgery doesn't only deliver a physical benefit in the form of increased gripping strength. The ability to eat independently, to carry out household chores and leisure activities offers mental rewards which benefit our social life, our daily habits and the roles we perform. Knowing that you can handle things yourself, of getting back your private life and restoring your identity as active parent, for example, or the guy that can go along for a beer with his mates is, in many cases, invaluable," says Johanna Wangdell.

Besides the individual progress this represents, reconstructive hand surgery also means that the requirement for personal assistance and specially adapted housing can be reduced and this can deliver savings for society as a whole.

Despite this, the hand surgery is performed only to a very modest extent outside Sweden: whereas four out of ten victims of spinal cord injuries are operated in Sweden only one out of ten undergo the surgery in the USA.

"Few clinics in the world undertake as many operations per year of this type as the Sahlgrenska University Hospital. This means that victims of spinal cord injuries from across Europe come to the hospital for this surgery," explains Johanna Wangdell.

"This is the first study that focuses on the patient viewpoint and we can demonstrate that those who undergo this surgery experience a really high level of satisfaction. I hope that my studies will contribute to the surgery becoming available much more widely, both in Sweden and the rest of the world."
