Jurors find Jodi Arias eligible for death penalty

PHOENIX (AP) ? The same jury that convicted Jodi Arias of first-degree murder last week took less than three hours Wednesday to determine that the former waitress is eligible for the death penalty in the killing of her one-time lover.

The swift verdict sets the stage for the final phase of the trial to determine whether the 32-year-old Arias should be sentenced to life in prison or the death penalty for the 2008 murder of Travis Alexander in his suburban Phoenix home.

Prosecutors will call Alexander's family and other witnesses in an effort to convince the panel Arias should face the ultimate punishment. Arias' defense lawyers will have her family members testify, and likely others who have known her over the years, in an attempt to gain sympathy from jurors to save her life. It's not yet known if Arias will testify.

Arias showed no emotion Wednesday after the jury returned a decision that was widely expected given the violent nature of the killing. She slashed Alexander's throat, stabbed him in the heart and shot him in the forehead after a day of sex at his home in June 2008. The victim suffered a total of nearly 30 knife wounds in what prosecutors described as an attack fueled by jealous rage after Alexander wanted to end his affair with Arias and prepared to take a trip to Mexico with another woman.

The jury simply had to determine the killing was committed in an especially cruel and heinous manner to complete the "aggravation phase" of the trial and move on to the penalty portion. The panel got the case around noon, took a lunch break and returned with the verdict around 3 p.m.

Alexander's family members sobbed in the front row as prosecutor Juan Martinez took the jury through the killing one more time earlier in the day. He described how blood gushed from Alexander's chest, hands and neck as the 30-year-old motivational speaker and businessman stood at the sink in his master bathroom and looked into the mirror with Arias behind him, a knife in her hand.

"The last thing he saw before he lapsed into unconsciousness ... was that blade coming to his throat," Martinez said. "And the last thing he felt before he left this earth was pain."

Wednesday's proceedings played out quickly, with only one prosecution witness and none for the defense. The most dramatic moments occurred when Martinez displayed photos of Alexander's corpse and the bloody crime scene for the jury, then paused in silence for two minutes to describe how long he said it took for Alexander to die at Arias' hands.

Arias, wearing a silky, cream-colored blouse, appeared to fight back tears most of the morning, but didn't seem fazed by the verdict. Afterward she chatted with her attorneys. Arias spent the weekend on suicide watch before being transferred back to an all-female jail where she will remain until sentencing.

Arias' attorneys didn't put on much of a case during the aggravation phase, offering no witnesses and giving brief opening statements and closing arguments. They said Alexander would have had so much adrenaline rushing through his body that he might not have felt much pain.

The only witness was the medical examiner who performed the autopsy and explained to jurors how Alexander did not die calmly and fought for his life as evidenced by the numerous defensive wounds on his body.

Minutes after her first-degree murder conviction last Wednesday, Arias granted an interview to Fox affiliate KSAZ, only adding to the circus-like environment surrounding the trial that has become a cable TV sensation with its graphic tales of sex, lies and violence.

"Longevity runs in my family, and I don't want to spend the rest of my natural life in one place," a tearful Arias said. "I believe death is the ultimate freedom, and I'd rather have my freedom as soon as I can get it."

However, Arias cannot choose the death penalty. It's up to the jury to recommend a sentence.

Arias acknowledged killing Alexander but said it was self-defense. She initially denied any involvement, even proclaiming to a detective while being interrogated in 2008: "I'm not guilty. I didn't hurt Travis. If I hurt Travis, I would beg for the death penalty."

She later blamed the attack on masked intruders. Two years after her arrest, she settled on self-defense.

Can your iPhone's digital footprints reveal your physical location?

Users of iPhones may be uniquely vulnerable to a new kind of cyberstalking that can reveal their real-life whereabouts, if they leave GPS and Wi-Fi activated.

By Ben Weitzenkorn,?Tech News Daily / May 13, 2013

An Australian computer-security expert has created an application that lets anyone see the locations of the last three Wi-Fi access points used by an Apple iPhone or iPad ? information that could be used to deduce where the iOS device user lives.

Melbourne-based researcher Hubert Seiwert's iSniff GPS, now freely available for anyone to download and use, combines three different Apple iOS features.

None of the features pose any threat to privacy on their own, but when combined could tell strangers a lot about you.

"This could be used to locate ... where people live," Seiwert told SC Magazine.

Three's a crowdsource

The first feature Seiwert used is well-known. Apple iOS devices that have both Wi-Fi and GPS turned on send the names and locations of all Wi-Fi access points they encounter back to the Apple mothership. The devices don't need to be connected to a specific access point for this to happen.

This feature helps Apple's mapping services. Google does the same thing with Android devices. Users of both kinds of devices can turn the data-sharing off.

The second feature is unique to iOS devices. Last year, security researcher Mark Wuergler of Miami-based Immunity Inc. found that iOS devices, when trying to connect to a Wi-Fi access point, will broadcast the unique network-interface IDs of the previous three Wi-Fi access points to which the devices actually did connect.

These unique network-interface IDs, called MAC addresses, can be physically located when run against online location services that keep databases of such things.

(MAC addresses differ from Wi-Fi access-point names such as "John's Wireless Router." MAC addresses are fixed, unique and used by machines to communicate with each other; Wi-Fi location names, also called SSIDs, can change at any time and exist for human convenience.)

Wuergler told the tech blog Ars Technica in March 2012 that he'd combined the Apple MAC-address feature with Google Location Services for Android to create a proof-of-concept application called "Stalker."

"I'll know where you work, I'll know where you live and know where you frequent," Wuergler said at the time. "If the last access point you connected to was your home, for example, I'll know right where to go to get to you later or get to your data."

Studies support population-based efforts to lower excessive dietary sodium intakes

May 14, 2013 ? Recent studies that examine links between sodium consumption and health outcomes support recommendations to lower sodium intake from the very high levels some Americans consume now, but evidence from these studies does not support reduction in sodium intake to below 2,300 mg per day, says a new report from the Institute of Medicine.

Despite efforts over the past several decades to reduce dietary intake of sodium, a main component of table salt, the average American adult still consumes 3,400 mg or more of sodium a day -- equivalent to about 1 ? teaspoons of salt. The current Dietary Guidelines for Americansurge most people ages 14 to 50 to limit their sodium intake to 2,300 mg daily. People ages 51 or older, African Americans, and people with hypertension, diabetes, or chronic kidney disease -- groups that together make up more than 50 percent of the U.S. population -- are advised to follow an even stricter limit of 1,500 mg per day. These recommendations are based largely on a body of research that links higher sodium intakes to certain "surrogate markers" such as high blood pressure, an established risk factor for heart disease.

The expert committee that wrote the new report reviewed recent studies that in contrast examined how sodium consumption affects direct health outcomes like heart disease and death. "These new studies support previous findings that reducing sodium from very high intake levels to moderate levels improves health," said committee chair Brian Strom, George S. Pepper Professor of Public Health and Preventive Medicine at the University of Pennsylvania Perelman School of Medicine. "But they also suggest that lowering sodium intake too much may actually increase a person's risk of some health problems."

While cautioning that the quantity of evidence was less-than-optimal and that the studies were qualitatively limited by the methods used to measure sodium intake, the small number of patients with health outcomes of interest in some of the studies, and other methodological constraints, the committee concluded that:

?evidence supports a positive relationship between higher levels of sodium intake and risk of heart disease, which is consistent with previous research based on sodium's effects on blood pressure;

?studies on health outcomes are inconsistent in quality and insufficient in quantity to conclude that lowering sodium intake levels below 2,300 mg/day either increases or decreases the risk of heart disease, stroke, or all-cause mortality in the general U.S. population;

?evidence indicates that low sodium intake may lead to risk of adverse health effects among those with mid- to late-stage heart failure who are receiving aggressive treatment for their disease;

?there is limited evidence addressing the association between low sodium intake and health outcomes in population subgroups (i.e., those with diabetes, kidney disease, heart disease, hypertension or borderline hypertension; those 51 years of age and older; and African Americans). While studies on health outcomes provide some evidence for adverse health effects of low sodium intake (in ranges approximating 1,500 to 2,300 mg daily) among those with diabetes, kidney disease, or heart disease, the evidence on both the benefit and harm is not strong enough to indicate that these subgroups should be treated differently from the general U.S. population. Thus, the evidence on direct health outcomes does not support recommendations to lower sodium intake within these subgroups to or even below 1,500 mg daily; and

?further research is needed to shed more light on associations between lower levels of sodium (in the 1,500 to 2,300 mg/day range) and health outcomes, both in the general population and the subgroups.

The report does not establish a "healthy" intake range, both because the committee was not tasked with doing so and because variability in the methodologies used among the studies would have precluded it.

The recent studies suggest that dietary sodium intake may affect heart disease risk through pathways in addition to blood pressure. "These studies make clear that looking at sodium's effects on blood pressure is not enough to determine dietary sodium's ultimate impact on health," said Strom. "Changes in diet are more complex than simply changing a single mineral. More research is needed to understand these pathways."

Insert Coin: Connectify Switchboard bonds all your internet connections into one

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.

Insert Coin Connectify Switchboard bonds all your internet connections into one

When we last saw Connectify, it had brought its Dispatch internet connection combining software to Kickstarter, doubled its funding goal and launched the product into market. However, customers using it said they wanted more than the web browsing and BitTorrent streaming speed-ups the load-balancing app provided, and were looking for so-called connection aggregation tech that'd allow quicker video streaming, VPN access and Skype calls, too. As a result, the company has just launched Switchboard, a cloud based app that combines all your internet connections but appears as only one IP address.

To make it work, the company built new software from scratch and put together a network of cloud servers across the world. The result is a "channel bonding" system that Connectify says will speed up all your online activities: Dropbox or SkyDrive uploads and downloads, Google Hangout video conferencing and video streaming from the likes of Netflix, to name a few. A quick test of the beta software on our end has worked seamlessly so far, requiring just a software installation and two or more internet connections (two ADSL lines in our case). On top of speeding everything up as promised, we also noticed that our IP address appeared as that of the server we were connected to instead of our local one, which could be a bonus for those trying to access US internet from abroad. Connectify's looking to grab $100,000 in funding this time around, with pledges starting at $50 -- so if you're looking to finally click that "HD" button on Vimeo, hit the source.

Reversing paralysis with a restorative gel

May 13, 2013 ? Some parts of the body, like the liver, can regenerate themselves after damage. But others, such as our nervous system, are considered either irreparable or slow to recover, leaving thousands with a lifetime of pain, limited mobility, or even paralysis.

Now a team of Tel Aviv University researchers, including Dr. Shimon Rochkind of TAU's Sackler Faculty of Medicine and Tel Aviv Sourasky Medical Center and Prof. Zvi Nevo of TAU's Department of Human Molecular Genetics and Biochemistry, has invented a method for repairing damaged peripheral nerves. Through a biodegradable implant in combination with a newly-developed Guiding Regeneration Gel (GRG) that increases nerve growth and healing, the functionality of a torn or damaged nerve could ultimately be restored.

This innovative project is now gaining international recognition. Its initial successes were reported at several recent scientific congresses, including the World Federation of Neurological Societies and the European Neurological Society. And the therapy, already tested in animal models, is only a few years away from clinical use, says Dr. Rochkind.

Like healing in the womb

A nerve is like an electrical cable. When severed or otherwise damaged, power can no longer be transferred and the cable loses its functionality. Similarly, a damaged nerve loses the ability to transfer signals for movement and feeling through the nervous system.

But Dr. Rochkind and Prof. Nevo found a way to breach the gap. In their method, two severed ends of a damaged nerve are reconnected by implanting a soft, biodegradable tube, which serves as a bridge to help the nerve ends connect. The innovative gel which lines the inside of the tube nurtures nerve fibers' growth, encouraging the nerve to reconnect the severed ends through the tube, even in cases with massive nerve damage, Dr. Rochkind says.

The key lies in the composition of the gel, the researchers say, which has three main components: anti-oxidants, which exhibit high anti-inflammatory activities; synthetic laminin peptides, which act as a railway or track for the nerve fibers to grow along; and hyaluronic acid, commonly found in the human fetus, which serves as a buffer against drying, a major danger for most implants. These components allow the nerve to heal the way a fetus does in the womb -- quickly and smoothly.

Keeping cells safe for transplant

The implant has already been tested in animal models, and the gel by itself can be used as a stand-alone product, acting as an aid to cell therapy. GRG is not only able to preserve cells, it can support their survival while being used for therapy and transplantation, says Dr. Rochkind. When grown in the gel, cells show excellent development, as well as intensive fiber growth. This could have implications for the treatment of diseases such as Parkinson's, for which researchers are actively exploring cell therapy as a potential solution.
