For those not involved in chemistry or biology, picturing a cell likely brings to mind several discrete, blob-shaped objects; maybe the nucleus, mitochondria, ribosomes, and the like.
There’s one part that’s often overlooked, save perhaps a squiggly line indicating the cell’s border: the membrane. But its role as gatekeeper is an...
Walking with a purpose — especially walking to get to work — makes people walk faster and consider themselves to be healthier, a new study has found.
The study, published online earlier this month in the Journal of Transport and Health, found that walking for different reasons yielded different levels of...
Contrary to popular wisdom, daily social media use is not a strong or consistent risk factor for depressive symptoms among adolescents, according to a new study by Columbia University Mailman School of Public Health researchers. The results are published in the Journal of Adolescent Health.
“Increasingly, teenagers are active on social...
A compound given as a dietary supplement to overweight but otherwise healthy people in a clinical trial caused many of the patients to slim down, research by Oregon State University and Oregon Health & Science University showed.
The research, published in the Journal of Nutrition, analyzed the effects of 24 weeks...
Children wearing multifocal contact lenses had slower progression of their myopia, according to results from a clinical trial funded by the National Eye Institute, part of the National Institutes of Health. The findings support an option for controlling the condition, also called nearsightedness, which increases the risk of cataracts, glaucoma...
Researchers from Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, have discovered a new way to reverse antibiotic resistance in some bacteria using hydrogen sulphide (H2S).
Growing antimicrobial resistance is a major threat for the world with a projected 10 million deaths each year by 2050 if...
Invading cells’ private space — prying into their internal functions, decisions and communications — could be a powerful tool that may help researchers develop new immunotherapy treatment for cancer. As reported today in Cell, a research group at the Weizmann Institute of Science has developed a technology that enables them...
Researchers have been able to dial-up and down creatures’ lifespans by altering the activity of proteins found in roundworm cells that tell them to convert sugar into energy when their cellular energy is running low. Humans also have these proteins, offering up intriguing possibilities for developing longevity-promoting drugs. These new...
African-Americans have up to three times the risk of dying from strokes as people of European descent, yet there has been little investigation of if and how genetic variants contribute to their elevated stroke risk. Until now.
A large international team of scientists has completed the largest analysis of stroke-risk genes...
Scripps Research chemists Hans Renata, Ph.D., and Alexander Adibekian, Ph.D., have discovered a way to efficiently create a synthetic version of a valuable natural compound called caspofungin I, which has shown promise as an anti-cancer agent.
Through this, they were able to understand how the bacterial secretion is able to block...
