`puddingebola writes "A report in the journal Nature Neuroscience (paywalled) says scientists have observed epigenetic markers in bees that correspond to their roles in the society. From the article, 'Honeybees are born into their place in society. Those fed royal jelly as larvae emerge as queens and do little but lay eggs. The rest become worker bees and divvy up the jobs that need doing around the hive. While some worker bees remain at home, others take flight in search of nectar, pollen and other hive essentials. The entire honeybee workforce are genetically identical sisters. But analysis of the worker bees' DNA revealed that foragers had one pattern of chemical tags on their genes, while those that stayed home had another. When bees swapped one job for the other, their genetic tags changed accordingly.'"

Zocalo writes "The BBC has a fascinating look into the music download habits of the UK population based on stats compiled by Musicmetric. The stats, gathered through the monitoring of BitTorrent swarms and geo-locating the IPs, shows the hotspots for music copyright infringement across the UK and regional preferences for certain types of music. Some of the outliers are somewhat unusual though, suggesting some problems with the methodology or sample size, unless people on the Isle of Wight really do prefer trumpet-playing crooner Louis Armstrong to the likes of Rihanna and Ed Sheeran who top the lists nationwide. Not in the UK? There are some global stats on the ' Most pirated near you? tab' of the story. Better yet, if you want to crunch the numbers for yourself all of the data has been made available at the Musicmatch website under the Creative Commons Attribution Non-Commercial ShareAlike license and a RESTful API to access the data (free for non-commercial use, but requiring an API token) is also available."
MojoKid writes "Intel's next-generation CPU architecture, codenamed Haswell, puts heavy emphasis on reducing power consumption. Pushing Haswell down to a 10W TDP is an achievement, but hitting these targets requires collaboration. Haswell will offer finer-grained control over areas of logic that were previously either on or off, up to and including specific execution units. These optimizations are impressive, particularly the fact that idle CPU power is approaching tablet levels, but they're only part of the story. Operating system changes matter as well, and Intel has teamed up with Microsoft to ensure that Windows 8 takes advantage of current and future hardware. Haswell's 10W target will allow the chip to squeeze into many of the convertible laptop/tablet form factors on display at IDF, while Bay Trail, the 22nm, out-of-order successor to Clover Trail, arrives in 2013 as well. Not to mention the company's demonstration of the first integrated digital WiFi radio. Folks have been trading blows over whether Intel could compete with ARM's core power consumption. Meanwhile, Santa Clara has been busy designing many other aspects of the full system solution for low power consumption and saving a lot of wattage in the process." It's mildly amusing that Windows 8 is the first version to gain dynamic ticks, something Linux has had working since around 2007.
runner_one writes "Harold 'Sonny' White of NASA's Johnson Space Center said Friday (Sept. 14) at the 100 Year Starship Symposium that warp drive might be easier to achieve than earlier thought. The first concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre, however subsequent calculations found that such a device would require prohibitive amounts of energy, studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter. But recent calculations showed that if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring the warp drive could be powered by the energy of a mass as small as 500 kg. Furthermore, if the intensity of the space warps can be oscillated over time, the energy required is reduced even more."
wiredmikey writes "A new zero-day vulnerability affecting Internet Explorer is being exploited in the wild affecting IE 9 and earlier. The vulnerability, if exploited, would allow full remote code execution and enable an attacker to take over an affected system. Security researcher Eric Romang discovered the vulnerability and exploit over the weekend while monitoring some infected servers said to be used by the alleged Nitro gang. To run the attack, a file named 'exploit.html' is the entry point of the attack ... According to analysis by VUPEN, the exploit takes advantage of a 'use-after-free vulnerability' that affects the mshtml.dll component of Internet Explorer. Rapid7 on Monday released an exploit module for Metaspolit which will let security teams and attackers alike test systems."

An anonymous reader writes with this excerpt from the Christian Science Monitor: "'Russia has just declassified news that will shake world gem markets to their core: the discovery of a vast new diamond field containing 'trillions of carats,' enough to supply global markets for another 3,000 years. The Soviets discovered the bonanza back in the 1970s beneath a 35-million-year-old, 62-mile diameter asteroid crater in eastern Siberia known as Popigai Astroblem. They decided to keep it secret, and not to exploit it, apparently because the USSR's huge diamond operations at Mirny, in Yakutia, were already producing immense profits in what was then a tightly controlled world market."
An anonymous reader writes "Presenting at the IEEE High Performance Extreme Computing conference, a researcher from the University of Tennessee presented evidence that the iPad 2 is as fast as the original Cray-2 supercomputer. Performance improvements were made to the iPad 2 LINPACK software by writing Python for generating and testing various Assembly routines. The researcher also found that the ARM Cortex-A9 easily beats the NVIDIA/AMD GPUs and latest Intel/AMD workstation CPUs in performance-per-Watt efficiency."
1sockchuck writes "Data centers operators often tout their diesel backup generators as a symbol of their reliability. So why does Microsoft want to get rid of them? Microsoft says diesel generators are 'inefficient and costly' and is looking at alternatives to supply emergency backup power for its server farms, including fuel cells powered by natural gas. One possible option is the 'Bloom box,' which both Apple and eBay are using in their data centers (albeit with biogas as the primary fuel). Bloom is positioning its fuel cells as a way to forego expensive UPS units and generators, using the Bloom box for primary power and the utility grid for backup. It's a pitch that benefits from the current low price of natural gas." (Microsoft would like to stop using so much water, too.)
Amiga Trombone writes "Christopher Stringer is one of the world's foremost paleoanthropologists. He is a founder and most powerful advocate of the leading theory concerning our evolution: Recent African Origin or 'Out of Africa.' He now calls the theory into question: 'I'm thinking a lot about species concepts as applied to humans, about the "Out of Africa" model, and also looking back into Africa itself. I think the idea that modern humans originated in Africa is still a sound concept. Behaviorally and physically, we began our story there, but I've come around to thinking that it wasn't a simple origin. Twenty years ago, I would have argued that our species evolved in one place, maybe in East Africa or South Africa. There was a period of time in just one place where a small population of humans became modern, physically and behaviourally. Isolated and perhaps stressed by climate change, this drove a rapid and punctuational origin for our species. Now I don't think it was that simple, either within or outside of Africa.'"
jammag writes "Who better for a developer to love than another developer? Yet as a veteran coder describes, it's not always a good idea for a programmer to fall for another programmer. He describes his experience observing — and getting partially pulled into — a romance within a development team. Part of the problem, perhaps, is that some developers spend so much time buried in code that, well, they quickly find themselves out of their league. Then again, why not love among the code?"
BButlerNWW writes "VMware is in OpenStack now, but not everyone thinks that's such a good idea. One member of the newly created OpenStack Board of Directors says allowing VMware into the open source cloud project was a 'huge mistake' that could damage the project's market perception. Boris Renski is co-founder of OpenStack integration consultancy Mirantis and he says every enterprise he's worked with so far has been interested in OpenStack because they view it as an alternative to VMware. The board's vote earlier this month has now muddled the differences, he says. 'If OpenStack isn't an alternative to VMware, then what the hell is it?' Renski says."
First time accepted submitter nerdyalien writes "In the academic world, it's publish or perish; getting papers accepted by the right journals can make or break a researcher's career. But beyond a cushy tenured position, it's difficult to measure success. In 2005, physicist Jorge Hurst suggested the h-index, a quantitative way to measure the success of scientists via their publication record. This score takes into account both the number and the quality of papers a researcher has published, with quality measured as the number of times each paper has been cited in peer-reviewed journals. H-indices are commonly considered in tenure decisions, making this measure an important one, especially for scientists early in their career. However, this index only measures the success a researcher achieved so far; it doesn't predict their future career trajectory. Some scientists stall out after a few big papers; others become breakthrough stars after a slow start. So how we estimate what a scientist's career will look like several years down the road? A recent article in Nature suggests that we can predict scientific success, but that we need to take into account several attributes of the researcher (such as the breadth of their research)."

Lucas123 writes "The price of 2.5-in solid state drives have dropped by 3X in three years, making many of the most popular models less than $1 per gigabyte or about 74 cents per gig. Hybrid drives, which include a small amount of NAND flash cache alongside spinning disk, in contrast have reached near price parity with hard drives that hover around the .23 cents per gig. While HDDs cannot compare to SSDs in terms of IOPS generated when used in a storage array or server, it's debatable whether they offer performance increases in a laptop significant enough that justify paying three times as much compared with a high-end a hard drive or a hybrid drive. For example, an Intel 520 Series SSD has a max sequential read speed of 456MB/sec compared to a WD Black's 122MB/sec. The SSD boots up in 9 seconds compared to the HDD's 21 seconds and the hybrid drive's 12-second time. So the question becomes, should you pay three times as much for an SSD for twice the performance, or almost the same speeds when compared to a hybrid drive?"
