From low-carb to intermittent fasting, surgery to Ozempic — people turn to a seemingly never-ending array of diets, procedures and drugs to lose weight. While it has been long understood that limiting the amount of food eaten can promote healthy aging in a wide range of animals, including humans, a new study from University of Michigan has revealed that the feeling of hunger itself may be enough to slow aging.

Previous research has demonstrated that even the taste and smell of food can reverse the beneficial, life-extending effects of diet restriction, even without its consumption.

These intriguing findings drove first author Kristy Weaver, Ph.D., principal investigator Scott Pletcher, Ph.D...

A strong quake in the last year of the NASA Mars InSight mission, enabled researchers at ETH Zurich to determine the global thickness and density of the planet’s crust. On average, the Martian crust much thicker than the Earth’s or the moon’s crust, and the planet’s main source of heat is radioactive.

After more than three years of daily monitoring and with the power levels decreasing on InSight’s seismometer, researchers were rewarded with data from a sizeable Marsquake in May 2022. The surface waves observed from this estimated 4...

A team of astronomers has claimed that observations of a sun-like star orbiting a small black hole might actually be the indication of something far more exotic—the existence of a boson star, a star composed entirely of dark matter.

The Gaia survey, led by the European Space Agency, provided detailed maps of more than a billion stars in the Milky Way galaxy. While almost all of those stars behaved as expected, there were some surprises. For example, one star in particular was seen orbiting a dark companion.

The star itself was fairly typical, weighing in at 0.93 solar masses and with roughly the same chemical abundance as our own sun...
