Regularly in the news, grocery stores, and at the pump, we are experiencing the limits of our planetary supply.

Nobody likes needles, but they're necessary for delivering many vaccines and biologics into the body. But what if those could be puffed through the skin instead, with just a little pressure, like being hit in the arm with a foam toy? Today, scientists report steps toward making that a reality. Using powdered vaccines that don't require refrigeration and a system driven by compressed gas, their "MOF-Jet" could easily deliver therapeutics against cancer and other diseases in a relatively painless way.

Squids and octopuses are masters of camouflage, blending into their environment to evade predators or surprise prey. Some aspects of how these cephalopods become reversibly transparent are still "unclear," largely because researchers can't culture cephalopod skin cells in the lab. Today, however, researchers report that they have replicated the tunable transparency of some squid skin cells in mammalian cells, which can be cultured. The work could not only shed light on basic squid biology, but also lead to better ways to image many cell types.

Storm-ravaged Mississippi struggled on Sunday with the aftermath of a huge tornado that tore across the southern US state, killing at least 25 people, with devastated communities bracing for a fresh bout of extreme weather.

World-first 'phase change inks' that could transform how we heat and cool buildings, homes and cars—to achieve sophisticated 'passive climate' control—have been developed, with enormous potential to help reduce energy use and global greenhouse gas emissions.

Most climate models do not yet account for a new UC Riverside discovery: methane traps a great deal of heat in Earth's atmosphere, but also creates cooling clouds that offset 30% of the heat.

A history of participating in campus recreational sports can offset stress and contribute to academic competence even during high-stress periods such as a pandemic lockdown, shows a new study.

Many astonishingly creative people have lived lives cut tragically short by illness. Johannes Vermeer, Wolfgang Amadeus Mozart, Jane Austen, Franz Schubert and Emily Brontë are some famous examples.

Since time immemorial, humans around the world have gazed up in wonder at the night sky. The starry night sky has not only inspired countless works of music, art and poetry, but has also played an important role in timekeeping, navigation and agricultural practices in many traditions.

When the first object ever known to have visited the Earth's Solar System from outer space zoomed past in 2017, it was so strange that at least one leading astronomer was convinced it was an alien vessel.
