The body and the brain: Impact of mental, physical exertion on fatigue development

Thu, 30/07/2015 - 8:24pm
Do you ever notice how stress and mental frustration can affect your physical abilities? When you are worried about something at work, do you find yourself more exhausted at the end of the day? This phenomenon is a result of the activation of a specific area of the brain when we attempt to participate in both physical and mental tasks simultaneously.

HVTN 505 vaccine induced antibodies nonspecific for HIV

Thu, 30/07/2015 - 8:24pm
A new study helps explain why the candidate vaccine used in the HVTN 505 clinical trial was not protective against HIV infection despite robustly inducing anti-HIV antibodies: the vaccine stimulated antibodies that recognized HIV as well as microbes commonly found in the intestinal tract, part of the body's microbiome.

How to look for a few good catalysts

Thu, 30/07/2015 - 8:24pm
Two key physical phenomena take place at the surfaces of materials: catalysis and wetting. A catalyst enhances the rate of chemical reactions; wetting refers to how liquids spread across a surface. Non-wetting surfaces promote chemical reaction rates, new research confirms.

Bering Sea hotspot for corals and sponges

Thu, 30/07/2015 - 8:22pm
North of the Aleutian Islands, submarine canyons in the cold waters of the eastern Bering Sea contain a highly productive 'green belt' that is home to deep-water corals as well as a plethora of fish and marine mammals.

Paralyzed men move legs with new non-invasive spinal cord stimulation

Thu, 30/07/2015 - 8:22pm
Five men with complete motor paralysis were able to voluntarily generate step-like movements thanks to a new strategy that non-invasively delivers electrical stimulation to their spinal cords. The strategy, called transcutaneous stimulation, delivers electrical current to the spinal cord by way of electrodes strategically placed on the skin of the lower back. This expands to nine the number of completely paralyzed individuals who have achieved voluntary movement while receiving spinal stimulation.

Waking up HIV

Thu, 30/07/2015 - 8:22pm
Highly active anti-retroviral therapy has helped millions survive the human immunodeficiency virus. Unfortunately, HIV has a built-in survival mechanism, creating reservoirs of latent, inactive virus that are invisible to both HAART and the immune system. But now, researchers have identified a compound that activates latent HIV, offering the tantalizing possibility that the virus can be flushed out of the silent reservoirs and fully cured.

Nature has more than one way to grow a crystal

Thu, 30/07/2015 - 8:22pm
New findings have implications for questions regarding how animals and plants grow minerals into shapes that have no relation to their original crystal symmetry, and why some contaminants are difficult to remove from stream sediments.

Computer model forecasts flu outbreaks in a subtropical climate

Thu, 30/07/2015 - 8:20pm
It is possible to predict the timing and intensity of influenza outbreaks in subtropical climates like Hong Kong where flu seasons can occur at different times and more than once during a year, scientists have shown for the first time.

Earth's magnetic shield is much older than previously thought

Thu, 30/07/2015 - 8:20pm
Since 2010, the best estimate of the age of Earth's magnetic field has been 3.45 billion years. But now a researcher responsible for that finding has new data showing the magnetic field is far older.

Drought's lasting impact on forests

Thu, 30/07/2015 - 8:20pm
In a global study of drought impacts, forest trees took an average of two to four years to resume normal growth rates, a revelation indicating that Earth's forests are capable of storing less carbon than climate models have assumed.

Cheaper, high-performance prosthetic knee

Thu, 30/07/2015 - 5:11pm
Researchers report that they have designed a cheap prosthetic knee that mimics normal walking motion. The team reports that it has calculated the ideal torque that a prosthetic knee should produce, given the mass of the leg segments, in order to induce able-bodied kinematics, or normal walking.

Researchers resurrect ancient viruses in hopes of improving gene therapy

Thu, 30/07/2015 - 5:10pm
Researchers have reconstructed an ancient virus that is highly effective at delivering gene therapies to the liver, muscle, and retina. This discovery could potentially be used to design gene therapies that are not only safer and more potent than therapies currently available, but may also help a greater number of patients.
