Health officials on Thursday announced a slew of measures that seek to restrict access to gender-affirming health care for young transgender people in the U.S.

Our cells follow 24-hour circadian rhythms that regulate our blood sugar levels and are heavily influenced by light exposure. Scientists have harnessed this to show that just sitting by a window improves blood sugar control in people with type 2 diabetes

With new technologies comes new discoveries. Or so Spider Man’s Uncle Ben might have said if he was an astronomer. Or a scientist more generally - but in astronomy that saying is more true than many other disciplines, as many discoveries are entirely dependent on the technology - the telescope, imager, or processing algorithm, used to collect data on them. A new piece of technology, the Nancy Grace Roman Space Telescope, is exciting scientists enough that they are even starting to predict what kind of discoveries it might make. One such type of discovery, described in a pre-print paper on arXiv by Vito Saggese of the Italian National Institute for Astrophysics and his co-authors on the Roman Galactic Exoplanet Survey Project Infrastructure Team, is the discovery of many more multiplantery exoplanet systems an astronomical phenomena Roman is well placed to detect - microlensing.

In the era of mega constellations, spacecraft typically have less than a week to avoid crashes

In geometry, there are surfaces that do without an inside or outside—and some need at least four dimensions to exist

This NASA/ESA Hubble Space Telescope image features the blue dwarf galaxy Markarian 178 (Mrk 178) against a backdrop of distant galaxies in all shapes and sizes. Some of these distant galaxies even shine through the diffuse edges of Mrk 178.

A distant world with carbon in its atmosphere and extraordinarily high temperatures is unlike any other planet we’ve seen, and it’s unclear how it could have formed

Gemini North captured new images of Comet 3I/ATLAS after it reemerged from behind the Sun on its path out of the Solar System. The data were collected during a Shadow the Scientists session — a unique outreach initiative that invites students around the world to join researchers as they observe the Universe on the world’s most advanced telescopes.

The largest study so far into the genetics of chronic fatigue syndrome, or myalgic encephalomyelitis, has implicated 259 genes – six times more than those identified just four months ago
