Scientists Suggest Dehydrating a Layer of Earth’s Atmosphere to Fight Global Warming
A new climate intervention strategy aims to decrease the amount of water vapor in the stratosphere by injecting it with ice-forming nuclei. The idea is that, by reducing the water content, more heat in the form of infrared radiation would leak out into space. Scientists described the strategy a study published Wednesday in Science Advances.…

How Stress Could Make Cancer Spread
New research in mice may pinpoint how chronic stress can fuel the spread of cancer. The study found evidence that stress can induce changes to certain immune cells that inadvertently make it easier for cancer cells to metastasize and invade other parts of the body. The findings emphasize the need to manage stress following a…

NASA Probe Spots History-Making Odysseus Lander on the Moon
Following a less-than-perfect touchdown, the Odysseus lander has been spotted from lunar orbit while lying on its side on the surface of the Moon. The lunar lander also beamed back its first images from the Moon as it fights to stay alive before it runs out of power. NASA’s Lunar Reconnaissance Orbiter (LRO) captured images…

Physicists Measure Gravity of Smallest Mass Yet
Despite keeping us grounded and warping light that travels through space, gravity is actually quite a weak force. The smaller the mass, the less gravity appears to have any pull, until at quantum scales it appears to have no force at all. Now, physicists in England and Europe have measured a tiny—but apparent—gravitational pull on…
