Safely landing a spacecraft that’s falling from the sky very quickly is easier said than done.
A schematic shows a perovskite solar cell being irradiated with a damaging (red) and a healing (green) proton beam.

Spacecraft exteriors that automatically heal from radiation damage would change the game − one material shows promise.
The Hubble Space Telescope is nearing its 35th birthday.

Underwater construction is a complex and difficult task, but engineers have developed several ways to build underwater … mostly by not building underwater at all.
Studying pregnancy from multiple disciplines could provide new insights.

How and why preterm birth happens is still unclear, in part because research on pregnancy tends to focus on developmental biology.
Protein wave oscillations open a window into living cells.

Researchers can create ‘single-cell radios’ using bacterial proteins to transmit the invisible activities within cells.
The physics of how ions flow in supercapacitors required an update.

What mathematicians call ‘disordered collections’ can help engineers explore real-world worst-case scenarios. The simple card game Set illustrates how to predict internet and electrical grid failures.
Cracked roads and sidewalks generate big costs for cities.

It’s unclear exactly what happened to violently shake up LATAM flight 800, but the moral for passengers is clear: wear your seatbelt.
Why do batteries lose charge more quickly when it’s cold?

Electric vehicles are catching on across the US, but they’re also catching on fire in colder regions like the Northeast and Midwest.
3D printing can be used to build with all kinds of materials – even those that go ‘boom.’

‘Energetic’ materials are ones that readily ignite or detonate. The shapes of those materials have a big effect on how they burn or blow up.
Dream Chaser would ferry cargo, and eventually crew, to low-Earth orbit.

Spaceplanes seemed out of favour when the shuttle was retired in 2011; they now seem to be making a comeback.
Condensation and cold combine to create that layer of ice on car windshields in winter.
