Studying an atomic clock on-board a spacecraft inside the orbit of Mercury and very near to the Sun might be the trick to uncovering the nature of dark matter, suggests a new study published in Nature Astronomy.

Dark matter makes up more than 80 per cent of mass in the universe, but it has so far evaded detection on Earth, despite decades of experimental efforts. A key component of these searches is an assumption about the local density of dark matter, which determines the number of dark matter particles passing through the detector at any given time, and therefore the experimental sensitivity...

Orbital observations unveil the presence of an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity. On Earth, shifting tectonic plates reshuffle the planet’s surface and make for a dynamic interior, so the absence of such processes on Mars led many to think of it as a dead planet, where not much happened in the past 3 billion years.

In the current issue of Nature Astronomy, scientists from the University of Arizona challenge current views of Martian geodynamic evolution with a report on the discover...

The massive growth of data centers that consume enormous amounts of energy has contributed significantly to power shortages worldwide. With rising demand for faster and more intelligent computers and devices, there is a pressing need to develop alternatives to traditional electronic components that will make these devices more energy-efficient.

In two recent studies, researchers at the Centre for Nano Science and Engineering (CeNSE), IISc, report the development of a highly energy-efficient computing platform that offers promise in building next-generation electronic devices.

Instead of using complementary metal-oxide semiconductors (CMOS) which are the building blocks of most electronic circuits today, th...

The effect of medicines on women and men can differ significantly. This also applies to the currently most promising anti-aging drug rapamycin, as researchers from the Max Planck Institute for Biology of Ageing in Cologne and University College London have now shown. They report in Nature Aging that the drug only prolongs the lifespan of female fruit flies, but not that of males.

In addition, rapamycin only slowed the development of age-related pathological changes in the gut in female flies. The researchers conclude that the biological sex is a crucial factor in the effectiveness of anti-aging drugs.

The life expectancy of women is significantly higher than that of men...
