Genetic analysis saves major apple-producing region of Washington state Posted: 23 Mar 2013 12:29 PM PDT A genetic analysis has saved a major apple-producing region of Washington state.

Acoustic monitoring of Atlantic cod reveals clues to spawning behavior Posted: 23 Mar 2013 12:29 PM PDT For decades researchers have recorded sounds from whales and other marine mammals, using a variety of methods including passive acoustic monitoring to better understand how these animals use sound to interact with each other and with the environment. Now, for the first time, researchers report using this technology to record spawning cod in the wild.

Nerve mapping technology improves surgery for compressed nerves Posted: 23 Mar 2013 12:24 PM PDT Nerve mapping technology allows surgeons to determine whether surgery has been effective for relieving pressure from compressed nerves, which often function poorly and cause sciatica or pain and weakness in muscles supplied by the nerve.

Physical activity during youth may help reduce fracture risk in old age Posted: 23 Mar 2013 12:24 PM PDT Get out there and regularly kick that soccer ball around with your kids, you may be helping them prevent a broken hip when they are older, say researchers.

Alterations in brain activity in children at risk of schizophrenia predate onset of symptoms Posted: 22 Mar 2013 02:43 PM PDT Research has shown that children at risk of developing schizophrenia have brains that function differently than those not at risk.

Computer simulations yield clues to how cells interact with surroundings Posted: 22 Mar 2013 02:43 PM PDT Scientists have developed a computer model of a protein that helps cells interact with their surroundings. Like its biological counterpart, the virtual integrin snippet is about twenty nanometers long. It also responds to changes in energy and other stimuli just as integrins do in real life. The result is a new way to explore how the protein connects a cell's inner and outer environments.

When a gene is worth two: Same gene fulfills different biological roles in plants Posted: 22 Mar 2013 12:41 PM PDT The notion that each gene can only codify for a single protein has been challenged for some years. Yet, the functional outcomes that may result from genes encoding more than one protein are still largely unknown. Now, botanists have discovered a gene -- ZIFL1 -- that produces two different proteins with completely distinct locations and functions in the plant.

Foods can help fight inflammation Posted: 22 Mar 2013 12:40 PM PDT Chronic inflammation can lead to chronic diseases, but it can be reduced naturally through the proper diet.

Protective properties of influenza vaccines revealed Posted: 22 Mar 2013 12:40 PM PDT Scientists have identified an important mechanism for stimulating protective immune responses following seasonal influenza vaccinations.

Making axons branch and grow to help nerve regeneration after injury Posted: 22 Mar 2013 09:54 AM PDT One molecule makes nerve cells grow longer. Another one makes them grow branches. These new experimental manipulations have taken researchers a step closer to understanding how nerve cells are repaired at their farthest reaches after injury.

Invasive species: Understanding the threat before it's too late Posted: 22 Mar 2013 09:53 AM PDT Catching rides on cargo ships and fishing boats, many invasive species are now covering our shorelines and compromising the existence of our native marine life. Scientists have examined what factors allow some invasive species to survive in their new environments and others to fail.

Engineers explain physics of fluids some 100 years after original discovery Posted: 22 Mar 2013 09:53 AM PDT Intuition says two or more jets of fluid should coalesce into a single stream of fluid, but that is not always the case. Velocity matters.

Atherosclerosis: Specific microRNAs promote inflammation Posted: 22 Mar 2013 09:53 AM PDT Atherosclerosis, an inflammatory reaction, is at the root of the most common forms of cardiovascular disease. Researchers have now identified a microRNA that plays a prominent role in the process, and offers a promising target for new therapies.

Novel method accurately predicts disease outbreaks Posted: 22 Mar 2013 09:52 AM PDT Scientists have developed a novel method to accurately predict dengue fever outbreaks several weeks before they occur.

New chemo drug gentler on fertility, tougher on cancer Posted: 22 Mar 2013 08:45 AM PDT A new gentler chemotherapy drug in the form of nanoparticles has been designed by scientists to be less toxic to a young woman's fertility but extra tough on cancer. This is the first cancer drug tested while in development for its effect on fertility using a novel, quick in vitro test designed by the scientists.

Common antibiotic linked to heart problems in patients with lung conditions Posted: 21 Mar 2013 05:56 PM PDT The antibiotic clarithromycin -- widely used for treating lower respiratory tract infections like pneumonia and acute exacerbations (sudden worsening) of chronic obstructive pulmonary disease -- may be associated with an increased risk of heart problems, finds a new study.
