Ringing in ears keeps brain more at attention, less at rest, study finds

Tinnitus, a chronic ringing or buzzing in the ears, has eluded medical treatment and scientific understanding. A new study by University of Illinois researchers found that chronic tinnitus is associated with changes in certain networks in the brain, and furthermore, those changes cause the brain to stay more at attention and less at rest.

Paper: Clinical signs best predictors of mortality in critically ill calves

Clinical signs may be better predictors of mortality in neonatal calves with diarrhea than blood pH levels and other laboratory findings, suggests a new study co-written by University of Illinois researcher Peter D. Constable.

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.

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.
