Despite their best efforts, no scientist has ever come close to stopping humans from aging. Even anti-aging creams can’t stop Old Father Time. But new research from Brigham Young University reveals you may be able to slow one type of aging — the kind that happens inside your cells. As long as you’re willing to sweat.

Heavy rain on Mars reshaped the planet’s impact craters and carved out river-like channels in its surface billions of years ago, according to a new study published in Icarus. In the paper, researchers from the Smithsonian Institution and the Johns Hopkins University Applied Physics Laboratory show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on…

Humans treat ‘inferred’ visual objects generated by the brain as more reliable than external images from the real world, according to new research published in eLife.
The study, from the University of Osnabrück, Germany, reveals that when choosing between two identical visual objects — one generated internally based on information from the blind spot and an external one — we are surprisingly…

Space weather events linked to human activity

Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather — which can include changes in Earth’s magnetic environment — are usually triggered by the sun’s activity, but recently declassified data on high-altitude nuclear explosion tests have provided a new look at the mechansisms that set off perturbations in that…
