Submission + - Crocodiles are alarmingly attuned to the cries of human infants (science.org)

sciencehabit writes: Whether they're in mortal peril or just suffering from indigestion, infants across the animal kingdom cry out to tell their parents they need help. Unfortunately for them, the parents aren't the only ones attuned to the cries of their vulnerable young. Nile crocodiles are uniquely sensitive to the wails of distressed primate babies, according to a new study—and the more anxious the cry, the more interested the crocs become.

Indeed, according to the research, published today in Proceedings of the Royal Society B: Biological Sciences, the reptiles are even better at identifying the emotional cues hidden in the wails of babies than we are—perhaps because they’ve evolved to home in on helpless prey.

“Oh, what a pity yum, yum!” jokes Stephan Reber, a cognitive zoologist at Lund University who was not involved in the study. On a more serious note, he says, the work raises the possibility that emotion may be communicated across species lines in more ways than scientists thought. “If crocs can do it, it probably means that many, many more animals can do it.”

Comment Re:Because assholes exploit loopholes (Score 1) 37

If my product fills one of a thousand shelfs in a store and there is physical logistics involved, a 30% cut seems well deserved. Now if the online store says my software will be one of a thousand or so, maybe 15%-20% cut seems fair (no significant logistics and floorsspace cost). But if it is one in a million or more... How can anybody justify more than 5% if everything is very easy to scale, maybe there is some review cost and payment processing. They can offer to promote it for some additional percents, but that cost should only go to the top x%

Submission + - The Proton Just got smaller (nature.com) 1

inflame writes: A new paper published in Nature has said that the proton may be smaller than we previously thought. The article states 'The difference is so infinitesimal that it might defy belief that anyone, even physicists, would care. But the new measurements could mean that there is a gap in existing theories of quantum mechanics. "It's a very serious discrepancy," says Ingo Sick, a physicist at the University of Basel in Switzerland, who has tried to reconcile the finding with four decades of previous measurements. "There is really something seriously wrong someplace."'

Would this indicate new physics if proven?

Swiss Firm Claims Boost In Android App Performance 132

Precision writes to inform us about the Swiss firm Myriad, which claims a 3x boost in Android app performance and longer battery life with a new virtual machine. Myriad says that its technology is 100% compatible with existing Android apps. "The tool is a replacement for the Dalvik virtual machine, which ships as part of the Android platform, and retains full compatibility with existing software. Dalvik Turbo also supports a range of processors including those based on ARM, Intel Atom, and MIPS Architectures."

An Open Source Compiler From CUDA To X86-Multicore 71

Gregory Diamos writes "An open source project, Ocelot, has recently released a just-in-time compiler for CUDA, allowing the same programs to be run on NVIDIA GPUs or x86 CPUs and providing an alternative to OpenCL. A description of the compiler was recently posted on the NVIDIA forums. The compiler works by translating GPU instructions to LLVM and then generating native code for any LLVM target. It has been validated against over 100 CUDA applications. All of the code is available under the New BSD license."
