A new nanodisc breakthrough lets scientists see viruses more realistically, revealing hidden clues that could lead to better vaccines. Viruses are highly effective at infecting human cells, largely because of specialized proteins that cover their outer surfaces. These proteins are also a key focus for vaccine design. To study them, scientists often create lab-made versions [...]

A very early study suggests flu antivirals might help reverse certain signs of accelerated aging in people with HIV. But more research is needed to confirm these effects.

A widely prescribed class of weight-loss and diabetes medications may be doing more than improving metabolic health. Drugs such as Ozempic and Wegovy have transformed the treatment of obesity and type 2 diabetes, helping millions lose weight and improve metabolic health. But scientists are increasingly uncovering effects that extend far beyond the scale. Research has [...]
