SpaceX promises a step change in performance for cell phone users around the world.

Radio astronomy took another step forward recently, with the completion of Phase III of the Murchison Widefield Array (MWA) in Western Australia. We’ve reported before on how the MWA has investigated everything from SETI signals to the light from the earliest stars. WIth this upgrade, the MWA will continue to operate with much needed improvements while the radio astronomy awaits the completion of the successor it helped enable - the Square Kilometer Array (SKA).

Jupiter hosts the brightest and most spectacular auroras in the Solar System, and its largest moons (the Galileans) create their own auroral signatures known as “satellite footprints” in the planet’s atmosphere. Until now, astronomers had detected the auroral signatures of three Galileans (Io, Europa, and Ganymede), but not Callisto. Thanks to an international team, close-up images of Callisto's footprints have been seen at last.

The JWST is performing a new multi-wavelength survey called MINERVA (Medium-band Imaging with NIRCam to Explore ReVolutionary Astrophysics). It'll study four extragalactic fields in greater detail and depth, and will help us understand the Cosmic Dawn.

Astronomers struggle to detect small exoplanets directly. One tool they use is to search for the effects these planets have on debris disks around stars. Clues in these disks tell astronomers where they can find sub-Jupiter mass exoplanets.

There is growing opposition to environmental policies around the world, but could researchers have found a way around this, asks Graham Lawton

Diagnosing mental health conditions like anxiety and depression can be difficult, but it turns out that your nose could help doctors understand when you are feeling the strain, says Gillian Forrester

We know fermented foods do us good, but the ZOE founder's new book still surprises with fascinating facts - and avoids feeling like an ad for his gut supplements, says Helen Thomson

Next to the flashy realm of AI, materials may seem quaint. But new quantum research could yield revolutionary breakthroughs, with the power to transform our world

"This forces us to rethink the starting conditions for our planet’s water system."

Most human populations evolved to cope with low or high local levels of micronutrients such as zinc, but these localised adaptations might now be problematic

An exceptionally loud collision between two black holes has been detected by the LIGO gravitational wave observatory, enabling physicists to test a theorem postulated by Stephen Hawking in 1971
