Fast, simple diagnostic test specific to 2014 Ebola outbreak

Posted: 10 Oct 2014 05:40 AM PDT

Researchers have developed a fast and simple diagnostic test solution specific to the 2014 Ebola outbreak. With the current epidemic of Ebola virus in West Africa, scientists are racing to provide an easy-to-use, affordable solution for screening suspect Ebola patients.

Mechanism that repairs brain after stroke discovered

Posted: 10 Oct 2014 05:38 AM PDT

A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered by researchers. A stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to an interruption of blood flow and therefore a shortage of oxygen. Many nerve cells die, resulting in motor, sensory and cognitive problems. The researchers have shown that following an induced stroke in mice, support cells, so-called astrocytes, start to form nerve cells in the injured part of the brain.

The dwindling stock of antibiotics, and what to do about it

Posted: 09 Oct 2014 06:03 PM PDT

Pharmaceutical companies have largely abandoned the business of discovering and developing antibiotics, and our stock of these "miracle drugs" is beginning to shrink. Researchers are working to create new models for drug discovery that could replace the failed private enterprise model.

Manipulating memory with light: Scientists erase specific memories in mice

Neuroscientists have used light to erase a specific memory in mice, showing how the hippocampus and cortex work together to retrieve memories.

Stunning finds from ancient Greek shipwreck

Posted: 09 Oct 2014 01:37 PM PDT

Divers and archaeologists have retrieved stunning new finds from an ancient Greek ship that sank more than 2,000 years ago off the remote island of Antikythera. The rescued antiquities include tableware, ship components, and a giant bronze spear that would have belonged to a life-sized warrior statue.

Discovery of new subatomic particle, type of meson, to 'transform' understanding of fundamental force of nature

Posted: 09 Oct 2014 08:26 AM PDT

The discovery of a new particle will "transform our understanding" of the fundamental force of nature that binds the nuclei of atoms, researchers argue. The discovery of the new particle will help provide greater understanding of the strong interaction, the fundamental force of nature found within the protons of an atom's nucleus.

Drinking decaf or regular coffee maybe good for the liver, study suggests

Posted: 09 Oct 2014 08:26 AM PDT

Researchers report that decaffeinated coffee drinking may benefit liver health. Results show that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes. This suggests that chemical compounds in coffee other than caffeine may help protect the liver.

A new measurement of dark matter in the Milky Way has revealed there is half as much of the mysterious substance as previously thought.

Around the world in 400,000 years: Journey of the red fox

Posted: 07 Oct 2014 11:45 AM PDT

For the first time, researchers have investigated ancestry across the red fox genome, including the Y chromosome, or paternal line. The data, compiled for over 1,000 individuals from all over the world, expose some surprises about the origins, journey and evolution of the red fox, the world's most widely distributed land carnivore.

Scientists discover how to 'switch off' autoimmune diseases

Posted: 03 Sep 2014 06:21 AM PDT

Scientists have made an important breakthrough in the fight against debilitating autoimmune diseases such as multiple sclerosis by revealing how to stop cells attacking healthy body tissue. Rather than the body's immune system destroying its own tissue by mistake, researchers have discovered how cells convert from being aggressive to actually protecting against disease.
