Coastal cities around the world are sinking, satellite data show
Of 99 coastal cities studied, nearly one-third are sinking. This leaves coastal communities increasingly vulnerable to rising seas.
- Animals
Orb-weaving spiders use their webs like external eardrums
Scientists discover that orb-weaving spiders listen with their legs, detecting sound vibrations that travel through their silken webs.
- Space
A star called ‘Earendel’ could be the most distant ever seen
A thin red arc found in an image from the Hubble Space Telescope shows starlight from nearly 13 billion years ago.
- Physics
Muons reveal the inner worlds of pyramids, volcanoes and more
Tracking these subatomic particles can uncover surprising hidden structures.
- Space
Gravitational waves ‘kicked’ a newborn black hole across space
Two black holes merged into one, and then sped off at around 5 million kilometers (3.1 million miles) per hour.
- Space
Some of the sun’s iconic coronal loops may be ghostly illusions
Wrinkles in the sun’s outer atmosphere might trick the eye into seeing glowing arches, scientists now report.
- Space
We finally have an image of the black hole at the heart of our galaxy
New observations from the Event Horizon Telescope reveal the chaotic region around the Milky Way’s central black hole, Sagittarius A*, in extreme detail.
- Planets
Analyze This: Some 5,000 planets orbit stars other than our sun
A new cache of confirmed exoplanet discoveries marks a milestone in planets found beyond our solar system.
- Tech
This sun-powered system delivers energy as it pulls water from the air
The device not only produces electricity but also harvests water for drinking or crops. It could be especially useful in remote and dry parts of the world.
- Materials Science
This new fabric can ‘hear’ sounds or broadcast them
With special fibers that convert tiny vibrations to voltages, a new fabric senses sound. Someday, such fabrics could monitor the body or aid hearing.
- Oceans
Night lights make even the seas bright
Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.
- Materials Science
New cloth cools you when you’re hot, warms you when you’re cold
Scientists 3-D printed the new fabric, which has even more tricks up its sleeve — such as conducting electricity and resisting radio waves.
