Hunt continues for mountain lion that mauled sleeping hiker

The hunt continued Monday for a mountain lion that over the weekend mauled a sleeping hiker in the Sierra Nevada foothills northwest of Nevada City, Calif.

The victim, 63, was treated for puncture and scratch wounds and released from a Grass Valley hospital. It was only the 15th confirmed mountain lion attack on a human in California since 1890.

The Bay Area man, who asked authorities not to release his identity, was driving to a trail head for the start of a hiking trip when he decided to spend the night under the stars at a spot he knew on a tributary of the Yuba River. He unfurled his sleeping bag, fell asleep and woke up about 1 a.m. Sunday to the open jaws of a mountain lion.

The hiker told California Department of Fish and Game wardens that the attack lasted 11/2 to 2 minutes. The animal bit him through his sleeping bag and cap, tore his scalp and scratched his back. The lion then walked away and briefly looked back before disappearing into the night.

The man, who was alone, drove himself to the hospital.

Mountain lions' primary prey are deer, which they usually kill by breaking the animal's neck or suffocating it by crushing the windpipe with a jaw hold. If lions find sleeping prey, they will go after it, said fish and game warden Patrick Foy. But he added that he had never heard of a lion attacking a person in this manner.

There have been lion attacks on pets and livestock in the area ? the remains of a domestic cat were found near the campsite ? but no reported encounters with people, Foy said.

There are an estimated 4,000 to 6,000 mountain lions in the state and confirmed attacks on humans are rare, although they have become more frequent in recent decades as more people move into their territory.

Of the 15 verified attacks in more than a century, about half have occurred in Southern California. Statewide, six have been fatal, the last occurring in Orange County's Whiting Ranch Regional Park in 2004.

Before last weekend, the most recent attack was in 2007, when a 70-year-old man was mauled in Prairie Creek Redwoods State Park in Humboldt County.

A team of state wardens and a federal wildlife tracker with dogs expect to be back in the field at dawn Tuesday for their third day of hunting for the animal. If it is found, it will be killed "in the interest of public safety," Foy said.

DNA analysis of the animal's traces on the hiker's sleeping bag and clothing revealed that it is a female.

The Fish and Game Department advises people not to run if they encounter a mountain lion. Rather, they should face the animal, make noise, wave their arms and throw rocks. If attacked, fight back.

Assembly OKs adding bank settlement into Calif law

SACRAMENTO, Calif. (AP) ? California would become the first state to write into law much of the national mortgage settlement negotiated this year with the nation's top five banks, and expand it to all lenders, under wide-ranging legislation state lawmakers approved Monday.

Majority Democrats sent the homeowner protection package to Gov. Jerry Brown despite opposition from business and lending organizations and most Republican legislators.

The Assembly approved the legislation on a 53-25 vote, and the Senate followed by voting 25-13.

The legislation would require large lenders to provide a single point of contact for homeowners who want to discuss loan modifications. It would prohibit lenders from foreclosing while the lenders consider homeowners' request for alternatives to foreclosure. And it would let California homeowners sue lenders to stop foreclosures or seek monetary damages if the lender violates state law.

The protections would benefit all California homeowners, not just those whose mortgages are with the five banks that signed the national settlement in February. And many of the restrictions would become permanent, while those in the nationwide agreement will end after five years.

It applies to all owner-occupied residences, but not commercial or rental properties.

Jose Vega drove 70 miles to Sacramento with his two young children to lobby lawmakers to pass the legislation after he spent three years battling to keep his home in the San Francisco-area city of Pittsburg.

In November 2009, he said, he found a trustee sale notice posted on his door 16 days after he was placed in a loan modification program. He was put into another modification program in the spring of 2010, only to have the bank again begin foreclosure proceedings.

Vega, 52, eventually kept his home after filing for bankruptcy and getting help from the office of Democratic U.S. Sen. Dianne Feinstein. Now he and his family owe $466,000 ? including the bank's legal fees ? on a home he said is worth about $200,000.

"I'm not asking for a handout. All I'm saying is, you created this mess, let's work something out," said Vega, a member of the Alliance of Californians for Community Empowerment. "Hopefully, California will lead the way so other states will follow."

Attorney General Kamala Harris said an estimated 700,000 California homeowners now are facing foreclosure, up from 500,000 in previous projections.

"They will now have a system that will offer them transparency and fairness," Harris said after the vote.

She helped negotiate the February settlement that requires Bank of America Corp., JPMorgan Chase & Co., Wells Fargo & Co., Citigroup Inc. and Ally Financial Inc. to pay $18 billion in penalties to California homeowners.

Harris said the California legislation is the next step in reforming the industry, even as a special task force of California Department of Justice prosecutors continues investigating mortgage abuses.

Key portions of her original proposal to write the settlement into state law were stalled by opposition from some of her fellow Democrats in the Legislature, until the right to sue banks and other measures were significantly narrowed.

"This legislation can be the catalyst not only for a recovery of California's real estate market, but a catalyst across the nation as borrowers everywhere will demand the same protections given to California borrowers, the same protections given to our families," said Democratic Assemblyman Mike Feuer, a member of the conference committee that negotiated the bill. "Those protections boil down to this: They ought to be treated fairly, they ought to be treated consistently."

Lenders' organizations joined by the California Chamber of Commerce said in a letter to lawmakers Friday that the final legislation is an improvement, though they still fear it will "encourage frivolous litigation" by borrowers who cannot realistically afford to stay in their homes.

The lending industry cited a study it commissioned by Beacon Economics, a Los Angeles-based research firm. It echoes industry arguments that letting homeowners sue their lenders, even in limited circumstances, will delay foreclosures and increase lenders' costs, potentially harming the shaky housing recovery and making it more difficult and costly to obtain mortgages.

The legislation can't address what lenders and opposing lawmakers said is the underlying problem: too many borrowers can't afford their payments.

"It's a mistake that will hurt this economy for years to come," said Republican Sen. Sam Blakeslee, a member of the conference committee.

Supporters of the bill say it still takes important steps.

"The point is ... not to launch an avalanche of lawsuits. What it's really about is having some meaningful accountability to ensure that servicers follow the rules," said Paul Leonard, director of the California office of the Center for Responsible Lending, a consumer group.

Previous efforts have repeatedly failed to clear the Legislature. Leonard said the national mortgage settlement and Harris' involvement are likely to make the difference this year.

Democratic Sen. Noreen Evans, who co-chaired the conference committee that negotiated the bill, said Brown's administration worked with Democrats on the legislation and has given every indication he would sign it into law. However, Brown declined to comment as he left the office of Senate President Pro Tem Darrell Steinberg moments before the vote.

The governor's office later issued a statement praising the legislation for establishing "important consumer protections that are long overdue" but stopped short of saying he will sign the bill.

The law would not take effect until Jan. 1, though Evans and Harris said they expect lenders would begin following the new rules immediately even if the penalties don't yet apply.

Hormone discovered that preserves insulin production and beta cell function in diabetes

ScienceDaily (July 2, 2012) ? Researchers at Duke University Medical Center have found protective, anti-diabetic functions for a hormone that, like insulin, is produced by the islet cells of the pancreas. The new hormone was found to stimulate insulin secretion from rat and human islet cells and protect islet cells in the presence of toxic, cell-killing factors used in the study.

The study, which was supported by JDRF, a global leader in type 1 diabetes research, appears in the July 3 issue of the journal Cell Metabolism.

The findings provide insight into the health and survival of beta cells, a type of islet cell that produces insulin to regulate sugar levels. The discovery could open pathways for further research toward prevention and treatments for type 1 diabetes and type 2 diabetes.

The researchers gave the hormone, TLQP-21 to Zucker Diabetic Fatty rats, which have a genetic propensity to develop type 2 diabetes. They saw a significant improvement in insulin and glucose (sugar) levels and less beta cell death in the treated animals.

"We think this finding is important because it is the first demonstration that TLQP-21 prevents deterioration of the beta cells and stimulates insulin secretion in the presence of glucose," said senior author Christopher B. Newgard, Ph.D., director of the Sarah W. Stedman Nutrition and Metabolism Center, and the W. David and Sarah W. Stedman Distinguished Professor. "Because diabetes starts to take hold when the number of beta cells dwindles and insulin production drops, finding the best way to produce more of this protective hormone could be valuable."

Although the researchers have so far only tested TLQP-21 in models of type 2 diabetes, they plan to test the hormone in type 1 in future studies.

Both types of diabetes are characterized by a loss of functional beta cell mass. Type 1 is an autoimmune disease characterized by selective and progressive loss of functional insulin-producing beta cells and is more severe. Type 2 is a disease characterized by beta cell dysfunction as well as peripheral insulin resistance. Most people with type 2 eventually become insulin-dependent.

"These exciting findings provide novel insight into how beta cell health and survival may be regulated in the body," said Patricia Kilian, Ph.D., director of the beta cell regeneration program at JDRF. "We are looking forward to studies that will further test how this novel hormone affects beta cell function in T1D (type 1 diabetes) models."

TLQP-21 is similar in some of its functions to another naturally occurring hormone produced in the digestive tract, glucagon-like peptide-1 (GLP-1). Through different mechanisms, both hormones protect and promote insulin secretion. GLP-1 or drugs that stabilize it are widely used to treat type 2 diabetes, but with some side effects, including increased heart rate and reduced stomach emptying, that have resulted in cessation of therapy in some people.

"What's exciting is that in the animal studies of TLQP-21, we didn't see these side effects," said lead author Samuel B. Stephens, Ph.D., a postdoctoral researcher in the Stedman Center. "The rats had typical appetites and ate normal amounts of food, and didn't show any changes in heart rate or digestion patterns when they were given large doses of the hormone."

The next step is to find a small molecule that could stimulate the islet cells to produce more of the TLQP-21 hormone, or to develop more potent or stable versions of injected hormone. Research toward a longer-acting drug will help accelerate its eventual testing in type 1 diabetes, said Newgard, who is also a professor of Pharmacology and Cancer Biology.

The work was a collaboration with Geoffrey Pitt, M.D., Ph.D., an associate professor of medicine in cardiology who heads the Duke Ion Channel Research Unit, and Albert Y. Sun, M.D., a cardiovascular disease fellow in the Pitt lab, who ran the tests to determine whether TLQP-21 raised heart rates. Other authors of the study include Jonathan C. Schisler, Ph.D., Hans E. Hohmeier, M.D., Ph.D., and Jie An, Ph.D.

The work was supported by grants from the JDRF, the National Institutes of Health (DK58398), and an American Heart Association post-doctoral fellowship, as well as a sponsored research agreement with Eli Lilly, with whom Dr. Newgard consults.

Nike+ Basketball and Training stat tracking shoes launch, kick off 'Game On, World' challenge (video)

Nike Basketball and Training stat tracking shoes launch, kick off 'Game On, World' contest

While the Nike+ fitness tracking platform has been around for years, the footwear giant has only just unleashed shoes with the technology built right in. The Nike Hyperdunk+ (last seen skying through the FCC) is its first basketball shoe in the line, while the first training shoes are the Lunar Hyper workout+ for women and Lunar TR 1+ for men. All feature not only the new Nike+ Pressure Sensor that tracks its wearer's movement, but also lightweight Flywire construction and Lunarlon cushioning. Both can wirelessly transfer their data to apps on user's phones (currently iOS only, pre-iPhone 4S hardware will also need the $20 Nike+ Sport adapter) or PCs, tracking activity during games, height on a dunk or movement as part of a training workout or drill.

So what is Nike going to do with all that data? Its first plan for the summer is "Game On, World", which is a series of challenges inspired by pro athletes encouraging all Nike+ users to set their personal bests in various categories. If you're still not sure how all this comes together, there are several demo videos embedded after the break. Now all we need to do is find someone (else) to get all sweaty, let us know if it works and keep us on top of the leaderboard -- has anyone seen Dan Cooper lately?

First successful 'spoofing' of unmanned aerial vehicles

ScienceDaily (June 29, 2012) ? A University of Texas at Austin research team successfully demonstrated for the first time that the GPS signals of an unmanned aerial vehicle (UAV), or drone, can be commandeered by an outside source -- a discovery that could factor heavily into the implementation of a new federal mandate to allow thousands of civilian drones into the U.S. airspace by 2015.

Cockrell School of Engineering Assistant Professor Todd Humphreys and his students were invited by the U.S. Department of Homeland Security to attempt the demonstration in White Sands, New Mexico in late June. Using a small but sophisticated UAV along with hardware and software developed by Humphreys and his students, the research team repeatedly overtook navigational signals going to the GPS-guided vehicle.

Known as "spoofing," the technique creates false civil GPS signals that trick the vehicle's GPS receiver into thinking nothing is amiss -- even as it steers a new navigational course induced by the outside hacker. Because spoofing fools GPS receivers' on both their location and time, some fear that most GPS-reliant devices, infrastructure and markets are vulnerable to attacks. That fear was underscored -- but not proven -- when a U.S. military drone disappeared over Iran late last year and showed up a week later, intact, and in the care of Iranians who claimed to have brought the vehicle down with spoofing.

The recent demonstration by University of Texas at Austin researchers is the first known unequivocal demonstration that commandeering a UAV via GPS spoofing is technically feasible.

"I think this demonstration should certainly raise some eyebrows and serve as a wake-up call of sorts as to how safe our critical infrastructure is from spoofing attacks," said Milton R. Clary, a senior Department of Defense (DoD) Aviation Policy Analyst at Overlook Systems Technologies, which is working with the federal government to develop programs that identify and mitigate spoofing attacks.

Humphreys said his research team wanted to demonstrate the potential risks associated with spoofing early on in the Federal Aviation Administration's task to write the mandated rules that will allow government and commercial drones in the U.S. airspace by 2015.

"We're raising the flag early on in this process so there is ample opportunity to improve the security of civilian drones from these attacks, as the government is committed to doing," Humphreys said.

Prior to the White Sands demonstration, Humphreys and his students worked with university athletics officials to perform a trial run at the Darrell K. Royal stadium.

High school students visiting campus for the university's My Introduction to Engineering summer camp watched the demonstration and were able to ask Humphreys and his students questions about their work.

Humphreys began the research on GPS security prior to joining The University of Texas at Austin three years ago, but he said the research received a crucial boost of momentum and financial support from the university and the Cockrell School of Engineering.

"What's great at The University of Texas at Austin is this structure and culture in place that supports incoming professors with the funds to do risky types of research -- the kind that's so bold and forward-thinking that it might not have an outside sponsor to fund it yet," Humphreys said. "It's a distinct and valuable trait of the university that benefits me, my students and the types of research we can pursue."

The interdisciplinary research coupled undergraduate and graduate students from aerospace engineering and electrical and computer engineering; specifically, from the Center for Space Research and the Wireless Networking and Communications Group. Over the course of the project, students designed hardware and software, and learned to improvise on the spot when things didn't always go their way.

"During the demonstration at White Sands I was so impressed by how resourceful my students were in the face of technical setbacks we had in the beginning," Humphreys said. "They kept a steady hand and we prevailed in the end, which really showed me the flexibility of these young and bright minds."

Daniel Shepard, an aerospace engineering graduate student who lead the UAV spoofing effort, said he was grateful for the opportunity to do the hands-on research beginning when he was an undergraduate student.

"It's rewarding to lead research that has an impact on improving national security, and, on a personal level, this specific project had a lot of value for me because I was working on things, like software development, that I typically wouldn't be involved with as an aerospace student," Shepard said. "The unique fusion of electrical engineering and aerospace engineering has been very valuable for cultivating my engineering expertise."

During the spoofing demonstration at White Sands, the research team took control of a hovering UAV from about a kilometer away. Next year, they plan to perform a similar demonstration on a moving UAV from 10 kilometers away.
