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.
Paper: New mothers abused by partners at greater risk of suicidal thoughts
New mothers who are in abusive relationships are three times more likely to have suicidal thoughts, a new study suggests. Conducted with women in Brazil, the study is among a growing body of research to establish a link between suicidality and intimate partner violence among postpartum women in low- or middle-income countries.
The heart is a dynamic muscle that grows and shrinks in response to stressors such as exercise and disease. The secret to its malleability lies in individual cells, which get bigger or smaller depending on the heart’s needs. A new study of mouse hearts reveals a previously unknown mechanism by which heart cells control their size by ramping up or stopping the production of a key factor called PABPC1. The findings, reported in the journal eLife, could assist in the development of therapeutics that promote healthy heart growth and prevent disease.
Studies link nutrient, academic achievement in pre-adolescent children
Researchers can look into your eyes to determine whether you’re getting your lutein, a pigment found in green leafy vegetables that is known to accumulate in the brain. Two new studies find that children with higher lutein levels in the eye tend to do better than others on tests of cognition and academic achievement, even after accounting for other factors known to influence academic performance such as IQ, gender, body composition and physical fitness.
Herbs, spices on vegetables may increase their appeal to men, young adults
Adults who don’t routinely eat vegetables for lunch—especially men and younger adults—may be more likely to consume them if the vegetables are seasoned, University of Illinois researchers found in a new study of more than 530 adults.
Fred A. Kummerow, successful crusader against trans fats, dies at 102
Fred A. Kummerow, a pioneer in the study of dietary contributors to heart disease who led a decades-long crusade to remove trans fats from the food supply, died Wednesday, May 31, at his home in Urbana, Illinois. He was 102.
Chemical array draws out malignant cells to guide individualized cancer treatment
Melanoma is a particularly difficult cancer to treat once it has metastasized, spreading throughout the body. University of Illinois researchers are using chemistry to find the deadly, elusive malignant cells within a melanoma tumor that hold the potential to spread.
