Rare 'universal paralog' genes may reveal a pre-LUCA evolutionary record

All life on Earth shares a common ancestor that lived roughly four billion years ago. This so-called "last universal common ancestor" (LUCA) represents the most ancient organism that researchers can study. Previous research ...

Niobium's superconducting switch cuts near-field radiative heat transfer 20-fold

When cooled to its superconducting state, niobium blocks the radiative flow of heat 20 times better than when in its metallic state, according to a study led by a University of Michigan Engineering team. The experiment marks ...

'Jetty McJetface': Star-shredding black hole may keep ramping up its radio jet until 2027 peak

A supermassive black hole with a case of cosmic indigestion has been burping out the remains of a shredded star for four years—and it's still going strong, new research led by a University of Oregon astrophysicist shows.

Ancient bird routes mapped via plant diversity

It's not what they intended to do or expected to find. They're not even all that interested in birds. When Andre Naranjo and his colleagues began work on a new study published in the Botanical Journal of the Linnean Society, ...

Our ocean's 'natural antacids' may act faster than we thought

Earth's ocean absorbs carbon dioxide from the atmosphere, helping to temper the impact of climate change but increasing ocean acidity. However, calcium carbonate minerals found in the seabed act as a natural antacid: Higher ...

Gaia data reveal three galactic open clusters in detail

Using ESA's Gaia satellite, astronomers have investigated three open clusters in the galactic disk, namely Berkeley 17, 18 and 39. Results of the new study, published January 21 on the arXiv pre-print server, yield crucial ...

Teaching machines to design molecular switches

In biology, many RNA molecules act as sophisticated microscopic machines. Among them, riboswitches function as tiny biological sensors, changing their 3D shape upon binding to a specific metabolite. This shape-change acts ...

Spider spinneret evolution: How a genome duplication event 438 million years ago set the stage

Scientists have uncovered a 400-million-year-old genetic secret that gave spiders the ability to produce silk and weave their webs. Spiders didn't begin their journey on Earth in the same way as they are known today. Arthropods ...

How topological surfaces boost clean energy catalysts

The oxygen reduction reaction (ORR) is a key process in fuel cells and metal-air batteries, technologies expected to play a central role in a low-carbon energy future. However, ORR proceeds slowly on most materials, limiting ...
