Farm manager plays leading role in postharvest loss

Science Daily - Wed, 06/08/2014 - 5:45pm
Some farms in Brazil lose 10 to 12 percent of their yield at various points along the postharvest route. According to an agricultural economist, when it comes to meeting the needs of the world's growing population that's a lot of food falling through the cracks. Interestingly, farm managers who are aware of the factors that contribute to postharvest grain loss actually lose less grain.

Mercury in the global ocean: three times more mercury in upper ocean since the Industrial Revolution

Science Daily - Wed, 06/08/2014 - 5:45pm
Mercury is a naturally occurring element as well as a by-product of such distinctly human enterprises as burning coal and making cement. Estimates of 'bioavailable' mercury -- forms of the element that can be taken up by animals and humans -- play an important role in everything from drafting an international treaty designed to protect humans and the environment from mercury emissions, to establishing public policies behind warnings about seafood consumption.

Enhanced international cooperation needed in Antarctica

Science Daily - Wed, 06/08/2014 - 5:45pm
Countries need to work together to ensure Antarctic research continues and key questions on the region are answered, researchers say. Key areas for scientific research in the region over the next two decades include looking at human impact on the region, understanding the evolution of Antarctic life, looking at the region's history, and the impact of climate change in the area, they say.

Ion duet offers tunable module for quantum simulator

Science Daily - Wed, 06/08/2014 - 5:45pm
Physicists have demonstrated a pas de deux of atomic ions that combines the fine choreography of dance with precise individual control. The ion duet is a component for a flexible quantum simulator that could be scaled up in size and configured to model quantum systems of a complexity that overwhelms traditional computer simulations.

Molecular competition drives adult stem cells to specialize, study shows

Science Daily - Wed, 06/08/2014 - 5:44pm
Adult organisms ranging from fruit flies to humans harbor adult stem cells, some of which renew themselves through cell division while others differentiate into the specialized cells needed to replace worn-out or damaged organs and tissues. Understanding the molecular mechanisms that control the balance between self-renewal and differentiation in adult stem cells is an important foundation for developing therapies to regenerate diseased, injured or aged tissue.

Facebook Seeks Devs To Make Linux Network Stack As Good As FreeBSD's

Slashdot - Wed, 06/08/2014 - 5:30pm
An anonymous reader writes Facebook posted a career application which, in their own words is 'seeking a Linux Kernel Software Engineer to join our Kernel team, with a primary focus on the networking subsystem. Our goal over the next few years is for the Linux kernel network stack to rival or exceed that of FreeBSD.' Two interesting bullet points listing "responsibilities": Improve IPv6 support in the kernel, and eliminate perf and stability issues. FB is one of the worlds largest IPv6 deployments; Investigate and participate in emerging protocols (MPTCP, QUIC, etc) discussions,implementation, experimentation, tooling, etc.

Researchers Make Fruit Flies Perform Aerobatics Like Spitfire Pilots

Slashdot - Wed, 06/08/2014 - 5:16pm
KentuckyFC (1144503) writes Researchers from Cornell University glued a tiny magnetic bar to the back of fruit flies and allowed them to fly through an electromagnet. Pulsing the magnet then causes the flies to roll in mid-air, like victorious Spitfire pilots. The work isn't entirely frivolous. The team was studying how fruit flies achieve stable flight when they ought to be particularly susceptible to being rolled by tiny gusts of air. It turns out that fruit flies have incredibly fast reactions. They respond to being rolled within a single wing beat, that's 5 milliseconds, flapping their wings asymmetrically to regain stable flight. That kind of reaction time makes them one of the fastest creatures in the animal world. By comparison, the visual startle response in flies takes 20 milliseconds and the quickest reactions humans can manage is about 100 milliseconds.
