redletterdave writes "Chinese scientists have cloned a genetically modified sheep containing a 'good' type of fat found naturally in nuts, seeds, fish and leafy greens that helps reduce the risk of heart attacks and cardiovascular disease. The gene, which is linked to the production of polyunsaturated fatty acids, was inserted into a donor cell taken from the ear of a Chinese Merino sheep. The cell was then inserted into an unfertilized egg and implanted into the womb of a surrogate sheep. With any luck, this process could be replicated in the future to clone more animals for safe and healthy consumption."

benfrog writes "In a blog post, Mark Shuttleworth announced some changes for Ubuntu 12.10 (due in October), including the code name (Quantal Quetzal — no, really) and a theme update. He said, 'That will kick off with a project on typography to make sure we are expressing ourselves with crystal clarity – making the most of Ubuntu’s Light and Medium font weights for a start. And a project on iconography, with the University of Reading, to refine the look of apps and interfaces throughout the platform. It’s amazing how quaint the early releases of Ubuntu look compared to the current style. And we’re only just getting started! In our artistic explorations we want to embrace tessellation as an expression of the part-digital, part-organic nature of Ubuntu.' Some other more meaningful announcements include a focus on the cloud in the server version and the lack of a transition from Upstart to systemd."
sciencehabit writes "Traumatic experiences in early life can leave emotional scars. But a new study suggests that violence in childhood may leave a genetic mark as well. Researchers have found that children who are physically abused and bullied tend to have shorter telomeres — structures at the tips of chromosomes whose shrinkage has been linked to aging and disease."
sycodon writes with news of research into how nearby supernovae affected the development of life on Earth. "[Professor Henrik Svensmark] found that the changing frequency of nearby supernovae seems to have strongly shaped the conditions for life on Earth. Whenever the Sun and its planets have visited regions of enhanced star formation in the Milky Way Galaxy, where exploding stars are most common, life has prospered. Prof. Svensmark remarks in the paper, "The biosphere seems to contain a reflection of the sky, in that the evolution of life mirrors the evolution of the Galaxy.' ... The data also support the idea of a long-term link between cosmic rays and climate, with these climatic changes underlying the biological effects. And compared with the temperature variations seen on short timescales as a consequence of the Sun's influence on the influx of cosmic rays, the heating and cooling of the Earth due to cosmic rays varying with the prevailing supernova rate have been far larger.""
tlhIngan writes "This week is Motorola's lucky week; they've won twice in two separate patent suits. First, an ITC judge has ruled that Microsoft's Xbox 360 has violated 4 of 5 patents related to h.264. This is just a preliminary ruling (PDF) and both Microsoft and Motorola will face an ITC panel later this year. In the other case, the ITC judge has ruled Apple violates a 3G patent, one that a German court ruled that Apple didn't violate earlier this year. "
steveb3210 writes "Physicists have demonstrated that making a decision about whether or not to entangle two photons can be made after you've already measured the states of the photons." Here's the article's description of the experiment: 'Two independent sources (labeled I and II) produce pairs of photons such that their polarization states are entangled. One photon from I goes to Alice, while one photon from II is sent to Bob. The second photon from each source goes to Victor. Alice and Bob independently perform polarization measurements; no communication passes between them during the experiment—they set the orientation of their polarization filters without knowing what the other is doing. At some time after Alice and Bob perform their measurements, Victor makes a choice (the "delayed choice" in the name). He either allows his two photons from I and II to travel on without doing anything, or he combines them so that their polarization states are entangled. A final measurement determines the polarization state of those two photons. ... Ma et al. found to a high degree of confidence that when Victor selected entanglement, Alice and Bob found correlated photon polarizations. This didn't happen when Victor left the photons alone.'
gManZboy writes "The vulnerability of wireless medical devices to hacking has now attracted attention in Washington. Although there has not yet been a high-profile case of such an attack, a proposal has surfaced that the Food and Drug Administration or another federal agency assess the security of medical devices before they're sold. A Department of Veterans Affairs study showed that between January 2009 and spring 2011, there were 173 incidents of medical devices being infected with malware. The VA has taken the threat seriously enough to use virtual local area networks to isolate some 50,000 devices. Recently, researchers from Purdue and Princeton Universities announced that they had built a prototype firewall known as MedMon to protect wireless medical devices from outside interference."
Taco Cowboy writes "Arctic methane release is a well recorded phenomenon. Methane stored in both permafrost (which is melting) and methane hydrates (methane trapped in marine reservoirs) are vulnerable to being released into the atmosphere as the planet warms. However, researchers who are trying to map atmospheric greenhouse gas concentrations on a global basis have discovered that the amount of methane emissions in the Arctic region do not total up. Further research revealed that significant amounts of methane releases came from the Arctic ocean (abstract) — as much as 2 milligrams of the gas is released per square meter of ocean, each day — presumably by marine bacteria surviving in low-nutrient environments."
MrSeb writes "Firefox 12 has been officially released, with only one major new feature: A silent, background updater. Now you will have to approve the Firefox Software Updater when you first install Firefox, but after that the browser will update silently — just like Chrome. In other news, the Find feature now reliably centers the page on any matches — hooray!" Here are the release notes, the list of bug fixes, and the download page.
New submitter microcars writes "Harvard recently sent a memo to faculty saying, 'We write to communicate an untenable situation facing the Harvard Library. Many large journal publishers have made the scholarly communication environment fiscally unsustainable and academically restrictive. This situation is exacerbated by efforts of certain publishers (called "providers") to acquire, bundle, and increase the pricing on journals.' The memo goes on to describe the situation in more detail and suggests options to faculty and students for the future that includes submitting articles to open-access journals. If Harvard paves the way with this, how long until other academic bodies follow suit and cut off companies such as Elsevier?"
lemmen writes "As widely expected, Google Drive has launched officially today. Google Drive is free for the first 5GB, while you can get an upgrade to 25GB for $2.50 a month. They say the service is available for PCs, Macs, Android devices, and soon iOS devices. According to Mercury News, '... the success of Drive will ride largely on whether Google can differentiate its offering from already established fast-growing cloud storage startups that were in the market first, such as Dropbox and Box, as well as Microsoft's SkyDrive service and big consumer media competitors like Apple's iCloud and Amazon's Cloud Drive. ... Existing Google Docs files, the centerpiece of Google's existing cloud storage offering, will move to the Google Drive service once users download apps and install the new service."
Gunkerty Jeb writes "Italian security researcher Luigi Auriemma was trying to play a trick on his brother when he accidentally discovered two vulnerabilities in all current versions of Samsung TVs and Blu-Ray systems that could allow an attacker to gain remote access to those devices. Auriemma claims that the vulnerabilities will affect all Samsung devices with support for remote controllers, and that the vulnerable protocol is on both TVs and Blu-Ray enabled devices. One of the bugs leads to a loop of endless restarts while the other could cause a potential buffer overflow."
Matching widespread predictions, The Bad Astronomer writes with word that "The private company Planetary Resources has announced that it plans to mine asteroids for water, air, and even precious metals in the next few years. Your initial reaction may be to snicker a bit, but it's headed by Peter Diamandis — who established the X Prize — has several ex-NASA personnel running the engineering, and also has the backing of a half-dozen or so billionaires. So this is no joke — their plan looks solid, and may very well be the first step in establishing a permanent human presence in space."
vvaduva writes "The North Carolina Board of Dietetics/Nutrition is threatening to send a blogger to jail for recounting publicly his battle against diabetes and encouraging others to follow his lifestyle... the state diatetics and nutrition board decided [Steve] Cooksey's blog — Diabetes-Warrior.net — violated state law. The nutritional advice Cooksey provides on the site amounts to 'practicing nutrition,' the board's director says, and in North Carolina that's something you need a license to do." If applied consistently, I think this would also clear out considerable space from the average bookstore's health section. (And it could be worse; he could have been offering manicures.)
