Slashdot - Fri, 16/05/2014 - 4:28am
angry tapir (1463043) writes "Embracing the widely used JSON data-exchange format, the new version of the PostgreSQL open-source database takes aim at the growing NoSQL market of nonrelational data stores, notably the popular MongoDB. The first beta version of PostgreSQL 9.4, released Thursday, includes a number of new features that address the rapidly growing market for Web applications, many of which require fast storage and retrieval of large amounts of user data."

Ten States Pass Anti-Patent-Troll Laws, With More To Come

Slashdot - Fri, 16/05/2014 - 2:02am
An anonymous reader writes "With patent reform stalled in the Senate, many states have decided to take up the issue themselves. 'As states kicked off their legislative sessions this winter, lawmakers responded to the threats against small businesses by writing bills that would ban "bad faith patent assertions" as a violation of consumer-protection laws. The bills target a specific type of patent troll: the kind that sends out vaguely worded letters demanding licensing fees. The thousands of letters sent out by the "scanner trolls" at MPHJ Technology are often brought up as a case-in-point. The new laws allow trolls that break rules around letter-writing to be sued in state court, either by private companies they've approached for licensing fees, or by state authorities themselves.'"

How Predictable Is Evolution?

Slashdot - Fri, 16/05/2014 - 12:11am
sciencehabit (1205606) writes "If the clock rewound, would organisms evolve the same way they did before? Humble stick insects may hold the answer to that long-running question in biology. Through studies of these bugs, whose bodies match the leaves the insects live on, researchers have found that although groups of the bug have evolved similar appearances, they achieved that mostly via different changes in their DNA. 'I think it says that repeatability of evolution is very low,' says Andrew Hendry, an evolutionary biologist at McGill University in Montreal, Canada, who was not involved with the work."

New Tech Super PACs Could Tap Into Google Riches

Slashdot - Thu, 15/05/2014 - 11:30pm
An anonymous reader writes "A for-profit university bankrolled by prominent tech firms and co-founded by futurist Ray Kurzweil is behind four separate super PACs formed this week, according to interviews and documents filed with the Federal Election Commission. Randi Willis, an official at Singularity University, confirmed to the Center for Public Integrity that leaders at her institution will later this year begin determining how to best use these new political committees, which could tap into the wealth of tech industry titans."

IBM Discovers New Class of Polymers

Slashdot - Thu, 15/05/2014 - 10:48pm
Charliemopps (1157495) writes "IBM Research has published a new paper to the journal, Science in which the describe a newly discovered class of Industrial Polymers that promise to revolutionize the fields of transportation, aerospace, and microelectronics. These materials resist cracking, have strength higher than that of bone, the ability to self-heal, and are completely recyclable. 'Codenamed Titan and Hydro, both of which came from the same reaction. One is rigid; it could become part of the next generation of computers. The other is a gel, so it it could be included in water-soluble nail polish.'"

Diabetics: Two large meals better than 6 small meals with same calories for controlling weight, blood sugar

Science Daily - Thu, 15/05/2014 - 10:44pm
Two large meals (breakfast and lunch), rather than six small meals with the same total calories, are better for controlling weight and blood sugar in people with type 2 diabetes, research shows. "Novel therapeutic strategies should incorporate not only the energy and macronutrient content but also the frequency and timing of food. Further larger scale, long-term studies are essential before offering recommendations in terms of meal frequency," the researchers conclude.

Airbus E-Fan Electric Aircraft Makes First Flight

Slashdot - Thu, 15/05/2014 - 10:05pm
An anonymous reader writes "The aviation industry has taken a tentative step toward electric power with the successful maiden flight of the Airbus E-Fan. The manufacturer known for the massive A380 jetliner began testing this small experimental aircraft last week, with the ultimate aim of lowering the huge carbon dioxide emissions from commercial flights. The E-FAN is powered by 120 lithium-polymer batteries, and can fly at speeds up to 136mph. Measuring just 19 feet from nose to tail, the compact aircraft show that Airbus probably isn't ready for commercial zero emissions flight just yet, but it does highlight the potential benefits."

Marijuana use involved in more fatal accidents since commercialization of medical marijuana

Science Daily - Thu, 15/05/2014 - 9:35pm
The proportion of marijuana-positive drivers involved in fatal motor vehicle crashes in Colorado has increased dramatically since the commercialization of medical marijuana in the middle of 2009, according to a study. The study raises important concerns about the increase in the proportion of drivers in a fatal motor vehicle crash who were marijuana-positive since the commercialization of medical marijuana in Colorado, particularly in comparison to the 34 non-medical marijuana states.

How some trypanosomes cause sleeping sickness while others don't

Science Daily - Thu, 15/05/2014 - 9:35pm
Trypanosome parasites transmitted by tsetse flies cause devastating diseases in humans and livestock. Different subspecies infect different hosts: Trypanosoma brucei brucei infects cattle but is non-infectious to humans, whereas T. b. gambiense and T. b. rhodesiense cause sleeping sickness in humans. A new study reveals how humans can fight off some trypanosomes but not others.

Complex interactions may matter most for longevity

Science Daily - Thu, 15/05/2014 - 9:35pm
Complex interactions among diet, mitochondrial DNA and nuclear DNA appear to influence lifespan at least as much as single factors alone, a new study of the biology of aging shows. The findings may help scientists better understand the underlying mechanisms of aging and explain why studies of single factors sometimes produce contradictory results.

'Physician partners' free doctors to focus on patients, not paperwork

Science Daily - Thu, 15/05/2014 - 9:33pm
Primary care doctors spend so much time on clerical duties that their time with patients is limited. A new study suggests that "physician partners" who would work on those time consuming administrative tasks can free up physicians’ time so that they can focus more on their patients. "Patients want their doctors to spend time with them and give them the attention that makes them feel more confident in their medical care — they don't want to just sit there while their doctor is on the computer," said the study's primary investigator

Walking may have profound benefits for patients with kidney disease

Science Daily - Thu, 15/05/2014 - 9:33pm
Among patients with chronic kidney disease who were followed for an average of 1.3 years, those who walked for exercise were 33% less likely to die and 21% less likely to need dialysis or a kidney transplant. Physical inactivity is common among patients with chronic kidney disease (CKD). The researchers found that the presence of other, or comorbid, conditions such as cardiovascular disease and diabetes was similar between walking and non-walking patients.

Apple's Revenge: iMessage Might Eat Your Texts If You Switch To Android

Slashdot - Thu, 15/05/2014 - 9:17pm
redletterdave (2493036) writes "When my best friend upgraded from an iPhone 4S to a Galaxy S4, I texted her hello. Unfortunately, she didn't get that text, nor any of the five I sent in the following three days. My iPhone didn't realize she was now an Android user and sent all my texts via iMessage. It wasn't until she called me about going to brunch that I realized she wasn't getting my text messages. What I thought was just a minor bug is actually a much larger problem. One that, apparently, Apple has no idea how to fix. Apple said the company is aware of the situation, but it's not sure how to solve it. One Apple support person said: 'This is a problem a lot of people are facing. The engineering team is working on it but is apparently clueless as to how to fix it. There are no reliable solutions right now — for some people the standard fixes work immediately; many others are in my boat.'"
