Slowing dangerous bacteria may be more effective than killing them, researchers report

A new study suggests it may be possible to slow dangerous infections by manipulating the messages microbes send to one another, allowing the body to defeat an infection without causing the bacteria to develop resistance to the treatment.

Increased risk of suicide, mental health conditions linked to sexual assault victimization

An analysis of nearly 200 independent studies involving more than 230,000 adult participants finds that having been sexually assaulted is associated with significantly increased risk of anxiety, depression, suicidality, post-traumatic stress disorder, substance abuse, obsessive-compulsive disorder and bipolar disorder.

Cicada wings may inspire new surface technologies

Researchers are looking to insects – specifically cicadas – for insight into the design of artificial surfaces with de-icing, self-cleaning and anti-fogging abilities. 

Study finds parallels between unresponsive honey bees, autism in humans

Honey bees that consistently fail to respond to obvious social cues share something fundamental with autistic humans, researchers report in a new study. Genes most closely associated with autism spectrum disorders in humans are regulated differently in unresponsive honey bees than in their more responsive nest mates, the study found.

Physical activity could combat fatigue, cognitive decline in cancer survivors

A new study indicates that cancer patients and survivors have a ready weapon against fatigue and “chemo brain”: a brisk walk.

Cognitive cross-training enhances learning, study finds

Just as athletes cross-train to improve physical skills, those wanting to enhance cognitive skills can benefit from multiple ways of exercising the brain, according to a comprehensive new study from University of Illinois researchers.

Lutein may counter cognitive aging, study finds

Spinach and kale are favorites of those looking to stay physically fit, but they also could keep consumers cognitively fit, according to a new study from University of Illinois researchers.

Massive simulation shows HIV capsid interacting with its environment

It took two years on a supercomputer to simulate 1.2 microseconds in the life of the HIV capsid, a protein cage that shuttles the HIV virus to the nucleus of a human cell. The 64-million-atom simulation offers new insights into how the virus senses its environment and completes its infective cycle.

Study: Omega-3 fatty acids fight inflammation via cannabinoids

Chemical compounds called cannabinoids are found in marijuana and also are produced naturally in the body from omega-3 fatty acids. A well-known cannabinoid in marijuana, THC, is responsible for some of its euphoric effects, but it also has anti-inflammatory benefits. A new study in animal tissue reveals the cascade of chemical reactions that convert omega-3 fatty acids into cannabinoids that have anti-inflammatory benefits – but without the psychotropic high. 

Brief interactions spur lasting waves of gene activity in the brain

A five-minute encounter with an outsider spurs a cascade of changes in gene activity in the brain that can last for hours, researchers report in a study of stickleback fish.
