Increasing paternal age has been linked to elevated health risks for the next generation, including higher risks of obesity and stillbirth. But what drives this increased risk remains unknown.

A clinical study shows that preoperative dynamic susceptibility contrast (DSC) perfusion magnetic resonance imaging (MRI) can help predict how microbubbles will distribute in the human brain. This is a key step toward optimizing ...

Soils store more carbon than the atmosphere and vegetation combined, with soil microorganisms playing the main role. As a result, the global soil carbon cycle—by which carbon enters, moves through, and leaves soils worldwide—exerts ...

Pioneering research by experts at the University of Sydney, the Baird Institute and the Royal Prince Alfred Hospital in Sydney has shown that heart muscle cells regrow after a heart attack, opening up the possibility of new ...

In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches ...

Scientists have recovered a genome of Treponema pallidum—the bacterium whose subspecies today are responsible for four treponemal diseases, including syphilis—from 5,500-year-old human remains in Sabana de Bogotá, Colombia. ...

Physicists have used a new optical centrifuge to control the rotation of molecules suspended in liquid helium nano-droplets, bringing them a step closer to demystifying the behavior of exotic, frictionless superfluids.

New research by Monash University and the ARC Center of Excellence for the Weather of the 21st Century analyzed close to three decades of weather data during the coral bleaching season and identified the prevalence of "doldrum ...
