First successful vaccination against 'mad cow'-like wasting disease in deer
Researchers at NYU Langone Medical Center and elsewhere say that a vaccination they have developed to fight a brain-based, wasting syndrome among deer and other animals may hold promise on two additional fronts: protecting US livestock from contracting the disease, and preventing similar brain infections in humans.

Alaska fish adjust to climate change by following the food
Not all species may suffer from climate change. A new analysis shows that Dolly Varden, a species of char common in southeast Alaska, adjust their migrations so they can keep feasting on a key food source -- salmon eggs -- even as shifts in climate altered the timing of salmon spawning.

Lost memories might be able to be restored, new UCLA study indicates
New UCLA brain research offers hope for patients in early stages of Alzheimer's disease that lost memories can be restored.

NASA's SDO captures images of 2 mid-level flares
The sun emitted a mid-level flare on Dec. 18, 2014, at 4:58 p.m. EST. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.

Atom-thick CCD could capture images
A synthetic two-dimensional material known as CIS could be the basis for ultimately thin imaging devices and optical sensors.

Early exposure to antidepressants affects adult anxiety and serotonin transmission
Now, a UCLA team has studied early developmental exposure to two different antidepressants, Prozac and Lexapro, in a mouse model that mimics human third trimester medication exposure. They found that, although these serotonin-selective reuptake inhibiting antidepressants were thought to work the same way, they did not produce the same long-term changes in anxiety behavior in the adult mice.

New technique reveals immune cell motion
Neutrophils, cells recruited by the immune system to fight infection, need to move through a great variety of tissues. New research shows how neutrophils move through confined spaces in the body. A new system can mimic tissues of different densities and stiffness, enabling improved development and testing of drugs.

Reducing emergency surgery cuts health care costs
In new findings published online in the journal Annals of Surgery on Dec. 19, 2014, researchers determined the hospital costs and risk of death for emergency surgery and compared it to the same operation when performed in a planned, elective manner for three common surgical procedures: abdominal aortic aneurysm repair, coronary artery bypass graft and colon resection.

The VuePod: Powerful enough for a gamer, made for an engineer
It's like a scene from a gamer's wildest dreams: 12 high-definition, 55-inch 3-D televisions all connected to a computer capable of supporting high-end, graphics-intensive gaming.On the massive screen, images are controlled by a Wii remote that interacts with a Kinnect-like Bluetooth device (called SmartTrack), while 3-D glasses worn by the user create dizzying added dimensions.

Making a good thing better
Berkeley Lab researchers carried out the first X-ray absorption spectroscopy study of a model electrolyte for lithium-ion batteries and may have found a pathway forward to improving LIBs for electric vehicles and large-scale electrical energy storage.
