The future of private equity

Steve Kaplan predicts lower default rates and higher recoveries in private equity deals due to increased efficiency and operating value. The industry can prevent overpriced deals by promoting larger equity commitments from financial sponsors.

HIV vaccine failure probably caused by virus used, says new research

Researchers found that people who had previously built up immunity to the adenovirus used in the trial had a higher risk of infection with HIV after receiving the vaccine. The study suggests that other adenovirus-based vaccines, such as those for tuberculosis and malaria, may also be at risk due to the same immune system reaction.

Analyzing structural brain changes in Alzheimer's disease

Researchers developed a fast and accurate method to quantify subtle brain volume loss in Alzheimer's patients, outperforming existing measures. The new technique identifies changes in memory regions, particularly the entorhinal cortex, as sensitive markers for early disease stages.

Marker of oxidative stress predicts heart disease outcomes

Researchers at Emory University School of Medicine have identified a substance in the blood that may predict an individual's risk for heart disease. High levels of cystine, an oxidized form of the amino acid cysteine, were found to be twice as likely to result in a heart attack or death over a few years.

Right-handed chimpanzees provide clues to the origin of human language

Research suggests that the left hemisphere's dominance in humans may stem from ancestral gestural communication, with right-handed gestures in chimpanzees indicating a similar lateralization. This study supports the idea that speech evolved from a gestural system and shares key features with human language.
