Antarctica could raise sea level faster than previously thought

A new study suggests Antarctica's ice sheet could become the largest contributor to global sea level rise earlier than thought. The analysis indicates a range of potential increases of 1-37 centimeters in this century, significantly higher than previous IPCC projections. This could have devastating impacts on coastal cities and communi...

New test reveals purity of graphene

Researchers have developed a simple method to detect contaminants on atom-thin graphene using terahertz spectroscopy. The technique involves placing the graphene on a layer of indium phosphide, which emits terahertz waves when excited by a laser pulse, allowing for non-contact detection and mapping of changes in electrical conductivity.

Researchers uncover clues about how the most important TB drug attacks its target

Scientists at Johns Hopkins Bloomberg School of Public Health have discovered a new clue to understanding how the most important medication for tuberculosis works. The antibiotic Pyrazinamide cuts off the energy production of Mycobacterium tuberculosis, killing the bacteria by disrupting PanD, an enzyme crucial to synthesis of co-enzym...

Vanderbilt-led study shows high-dose flu vaccine more effective in elderly

A Vanderbilt-led study published in the New England Journal of Medicine found that the high-dose flu vaccine is 24% more effective than the standard-dose vaccine in protecting persons ages 65 and over against influenza illness. The study, which enrolled 31,989 participants, showed that the high-dose trivalent vaccine induces significan...

Scared of crime? Good

A Michigan State University study suggests that adolescents who are more fearful of crime are less likely to become victims and offenders of violent acts. The research found that fearful youth tend to avoid potentially dangerous situations, leading to safer outcomes.

The Lancet Diabetes & Endocrinology: 2 out of every 5 Americans expected to develop type 2 diabetes during their lifetime

A major study estimates that nearly half of the US adult population will develop type 2 diabetes by age 20, with Hispanic men and non-Hispanic black women facing the highest risk. The study found a significant increase in lifetime risk of diabetes over 26 years, driven by rising rates and longer life expectancy.

Is empathy in humans and apes actually different?

Researchers directly compared human and bonobo yawn contagion, finding that strong relationships matter more than species for empathic responses. Humans respond more frequently to friends and kin, while bonobos do so equally, challenging the assumption that humans are more empathetic.
