It has remained mysterious for millennia, but we’re finally uncovering the profound role the lymphatic system plays in everything from preventing dementia to fighting cancer

Age-related macular degeneration is a common cause of vision loss, with existing treatments only able to slow its progression. But now an implant in the back of the eye and a pair of high-tech glasses have enabled people with the condition to read again

The discovery of a new array of molecules spouted from Enceladus indicates new promise for habitability within its frozen-over ocean.

The post New Study Identifies Organic Molecules Spewing from Saturn's Icy Moon Enceladus appeared first on Sky & Telescope.

The Search For Extra Terrestrial Intelligence (SETI) is evolving. We’ve moved on from the limited thinking of monitoring radio waves to checking for interstellar pushing lasers or even budding Dyson swarms around stars. To match our increased understanding of the ways we might find intelligence elsewhere in the galaxy, the International Academy of Astronautics (IAA) is working through an update to its protocols for what researchers should do after a confirmed detection of intelligence outside of Earth. Their new suggestions are available in a pre-print paper on arXiv, but were also voted on at the 2025 International Astronautical Congress (IAC) in Sydney, with potential full adoption early next year.

A special class of immune proteins protect us from pathogens but also drive inflammation and cell death

Turning the crank on a simple device filled with nanoparticles can remove serious pathogens from water in seconds, making it suitable for areas without electricity

A new WHO report warns of rising antimicrobial resistance, and researchers uncover satellite data leaks and insect surprises.

The launch campaign of the next satellite to join the Copernicus Sentinel-1 mission is progressing on schedule for launch on Tuesday, 4 November, on board an Ariane 6 rocket.

When Homo sapiens and Neanderthals interbred, a genetic variation affecting red blood cells may have hindered reproduction in women who were hybrids, and this might have played a part in Neanderthals’ demise

Space-based solar power has been gaining more and more traction recently. The recent success of Caltech’s Space Solar Power Project, which demonstrated the feasibility of transmitting power from space to the ground, has been matched by a number of pilot projects throughout the world, all of which are hoping to tap into some of the almost unlimited and constant solar energy that is accessible up in geostationary orbit (GEO). But, according to a new paper from a group of Italian and German researchers, there are plenty of constraints on getting that power down here to Earth - and most of them are more logistical than technical.

An analysis of patient records suggests that mRNA covid-19 vaccines boost the immune response to cancerous tumours when given soon after people start a type of immunotherapy, extending their lives

What can cryovolcanism on Pluto teach scientists about the dwarf planet’s current geological activity? This is what a recent study published in The Planetary Science Journal hopes to address as a team of researchers investigated potential cryovolcanic sites within specific regions on Pluto. This study has the potential to help scientists better understand the current geological activity, including how it can be active while orbiting so far from the Sun.

Mars has experienced multiple ice ages, with each one leaving less ice than the last. By studying craters that serve as “ice archives,” researchers traced how the red planet stored and lost its water over hundreds of millions of years. These frozen records not only reveal Mars’ long-term climate history but also identify hidden resources beneath the surface that could provide drinking water, oxygen, and even rocket fuel for future astronauts.

Astronomers are listening for cosmic gravitational waves in the rhythm of pulsars. But even after finding them, they will need to distinguish between cosmic waves and the more local waves of black holes.
