Study suggests life insurance should cover people treated for HIV

A study published in The Lancet found that people with HIV who are successfully treated with HAART and hepatitis C negative have a mortality rate similar to those with cancer. This preliminary actuarial evidence supports the idea that life coverage could be considered under specific conditions.

Coal-eating bacteria may improve methane recovery

Brookhaven chemist Mow Lin's team has developed bacteria that can use coal as a nutrient and adsorb or degrade contaminants, improving methane recovery. Laboratory tests have shown these microbes to absorb contaminant metals, degrade dissolved organics, and break down coal to release trapped methane.

'Status' decides whether or not a language survives

A mathematical model developed by Cornell University engineers quantifies language death and offers strategies to preserve endangered languages. The model attributes the decline of languages to competition for speakers, with higher-status languages like English dominating in multilingual societies.

Potent toxin reveals new antibiotic resistance mechanism

Researchers at University of Wisconsin-Madison uncover a potent toxin reveals new antibiotic resistance mechanism, where bacteria deploy a protein to intercept and inactivate the toxin. This mechanism points to the fact that bacteria continue to find new routes to evade antibiotics, threatening the fight against deadly bacteria.
