Research finds higher disease protection in fat cells in females

Research from the University of Cincinnati finds a higher presence of mitochondria in fat tissue in females. The research suggests this provides women protection against obesity and metabolic diseases. The study was published in Nature Metabolism. Mitochondria, explains Karthickeyan Chella Krishnan, Ph.D., assistant professor in the Department of Pharmacology and Systems Physiology in the UC College of Medicine, produce energy […]

New research finds air pollution reduces sperm counts through brain inflammation

Researchers have long known that air pollution can increase the risk of disorders such as obesity, diabetes, and fertility, but they did not know the exact mechanism for how it can lead to these health conditions. Now, University of Maryland School of Medicine (UMSOM) researchers have shown how air pollution reduces sperm count in mice by causing inflammation in the […]

New research underscores pollution’s impact on child health

Studies have shown air pollution is a major risk factor for respiratory infection—the leading cause of death among children under five—but bad air’s specific impacts on developing bodies have remained somewhat of a mystery. A Stanford-led study reveals a link between tiny airborne particles and child health in South Asia, a region beset with air pollution and more than 40 […]

Researchers find how iron deficient plants protect themselves from damaging light

Researchers have identified how iron deficient plants protect themselves from damaging light, according to a Dartmouth study. The study, published in Proceedings of the National Academy of Sciences, shows how plants lacking iron optimize photosynthesis, and it describes the genetic processes that regulate light protection in plants that lack sufficient levels of the mineral. We are trying to identify the […]

Losing Your Hair? You Might Blame the Great Stem Cell Escape.

Every person, every mouse, every dog, has one unmistakable sign of aging: hair loss. But why does that happen? Rui Yi, a professor of pathology at Northwestern University, set out to answer the question. A generally accepted hypothesis about stem cells says they replenish tissues and organs, including hair, but they will eventually be exhausted and then die in place. […]

Scientists turn into molecular detectives to find clues to why certain cancer therapies stop working

A new research study at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) turns cancer scientists into molecular detectives, searching for clues for why certain cancers are able to spread and evolve by studying tissues collected within hours of death. Led by Dr. Sameek Roychowdhury, this […]

UNLV neuroscientists bolster the connection between Type II diabetes and Alzheimer's disease

A team of UNLV neuroscientists has strengthened the link between Type II diabetes and Alzheimer's disease. In a study published in the September issue of the journal Communications Biology, researchers show that chronic hyperglycemia impairs working memory performance and alters fundamental aspects of working memory networks. Diabetes is a major risk factor for developing Alzheimer's disease, but it is not […]

Internet usage boosts cognitive function of retirees, finds study

Using the internet during your retirement years can boost your cognitive function, a new study has found. Researchers from Lancaster University Management School, the Norwegian University Science and Technology and Trinity College Dublin examined the cognitive function of more than 2,000 retired people from across Europe, and found that post-retirement internet usage is associated with substantially higher scores on tests. […]

Fact-checking is an effective tool to combat misinformation, study shows

Fact-checking reduces belief in misinformation and leaves a more enduring mental imprint than false claims, according to a new study published today in the Proceedings of the National Academy of Sciences. The study shows fact-checking is an effective tool to combat misinformation across countries, cultures, and political environments. While previous research has shown that factual corrections reduce false beliefs, even […]
