According to a recent announcement of researchers, they noted several genetic markers that could be helpful in determining the risks of developing post-traumatic stress disorder among the United States soldiers.

After that, the researchers were trying to find that link. To do so, they took some blood samples from United States Marines and examined them. Blood samples were taken before and after deployment.

As per Michael S. Breen, a researcher from the University of Southampton and senior study author, after comparing US Marines who develop post-traumatic stress disorder symptoms to those who do not, difference in genes can be measured. Breen said that measurement of dynamic relationships could be helpful in knowing the pathology of PTSD.

23andMe, the Google-backed genetic-testing startup, is planning to expand its working and will now make new medicines to cure people affected by diseases.

Although Palcohol, or powdered alcohol, has received government approval, efforts to ban it nationwide are now underway.

According to Mark Phillips Palcohol’s maker, Palcohol comes in a pouch and can be turned into a cocktail by just adding water to it. They further told that it comes in four different varieties including rum, vodka, cosmopolitan and powderita.

He said, “If they’re an outdoor enthusiast and they’re going hiking, backpacking, biking, kayaking, boating – anywhere where weight is an issue, having powdered alcohol is a lot lighter than liquid alcohol”.

Experts are still concerned that the portability of this product can make its dangerous, especially for kids.

According to scientists, an experimental and non-invasive technique using ultrasound helps remove the brain plaques in mice, which could lead to Alzheimer’s disease.

According to the study in the journal Science Translational Medicine, using sound waves to penetrate tissue removed most of amyloid plaque in 75% of the animals studied, without causing any harm to brain tissue.

According to James Hendrix, director of global science initiatives for the Alzheimer's Association, "We know that amyloid interferes with the function of neurons and causes brain cells to die, but not everyone with amyloid in their brain will go on to develop Alzheimer's or another dementia".

On Thursday, NBC News Chief Medical Editor Nancy Snyderman announced that she has decided to leave her job. Last fall, Snyderman had broken a voluntary quarantine after covering the Ebola epidemic.

Snyderman said she has decided to return to academic medicine. According to the physician, she will take up a faculty position at a major United States medical school. She said, “More needs to be done to communicate medicine and science to our viewers and citizens, especially in times of crisis, and with my experiences in the field and on air, that is going to be a priority for me”.

David Rennie went through tough time for two years as he had to go through regular dialysis because of kidney problems he had. The 54-year-old Shelton resident was provided a means of survival by dialysis, but he was not able to perform certain daily tasks because of the condition.
