New findings can redefine the diagnosis of mild cognitive impairment in men and women

Using sex-specific scores on memory tests may change the diagnosis for 20 percent of those currently diagnosed with mild cognitive impairment (MCI), with possibly more women and fewer men being diagnosed with MCI, according to a new study published online in the journal Neurology.

Researchers analyze stress levels of adolescents severely affected by autism

When people become stressed, their bodies can respond by sweating. Now, researchers at the University of Missouri are monitoring how much adolescents severely affected by autism sweat in order to better understand when behavioral issues, such as aggression, are likely to occur.

Genetic mechanisms could serve as a road map for screening new drugs to prolong healthy lifespan

The discovery in the 1990s that a mutation in a single gene of an experimental worm could double its lifespan set off a stampede of research on the molecular biology of aging and triggered hopes that drug therapies or other interventions could be developed to extend healthy human lifespan. But as is often the case in science, the genetic regulation of aging is more complicated than it first appeared.

Research may help explain how liquid organelles in cells coexist without merging

New research may help to explain an intriguing phenomenon inside human cells: how wall-less liquid organelles are able to coexist as separate entities instead of just merging together.

A Lego-like approach to enhance nature's own ability to attack bacteria

The Centers for Disease Control and Prevention considers antibiotic resistance one of the most urgent public health threats, one that affects communities worldwide. The ramifications of bacteria's ability to become resistant to antibiotics can be seen in hospitals, public places, our food supply, and our water.

New algorithm hand-picks which cancer mutations are promising targets for immunotherapy

As tumor cells multiply, they often spawn tens of thousands of genetic mutations. Figuring out which ones are the most promising to target with immunotherapy is like finding a few needles in a haystack.

Researchers discover most virulent representatives of listeriosis pathogen

The bacterium Listeria monocytogenes can cause listeriosis, a life-threatening infection in animals and humans. Contaminated food is a frequent source of infection. Elderly people, people with a weakened immune system and pregnant women are particularly at risk with a mortality rate of up to 30 per cent.
