Webb telescope observes potentially young Methane deposits on surfaces of Eris, Makemake. A team co-led by Southwest Research Institute found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected on their surfaces has the tell-tale signs of warm or even hot geochemistry in their rocky cores, which is markedly different than the signature of methane from a comet.

“We see some interesting signs of hot times in cool places,” said SwRI’s Dr. Christopher Glein, an expert in planetary geochemistry and lead author of a paper about this discovery.

The Kuiper Belt is a vast donut-shaped region of icy bodies beyond the orbit of Neptune at the edge of the solar syste...

Researchers can engineer cells to express new genes and produce specific proteins, giving the cells new parts to work with. But, it’s much harder to provide cells with instructions on how to organize and use those new parts. Now, new tools from University of Wisconsin–Madison researchers offer an innovative way around this problem.

Their research is published in the journal Cell.

Everything a cell does depends on how molecules are organized within the cell...

Researchers have been able to visualize the third class of magnetism, called altermagnetism, in action. Ferromagnetism and antiferromagnetism have long been known to scientists as two classes of magnetic order of materials. Back in 2019, researchers at Johannes Gutenberg University Mainz (JGU) postulated a third class of magnetism, called altermagnetism. This altermagnetism has been the subject of heated debate among experts ever since, with some expressing doubts about its existence...

In a new study, scientists have mapped magnetic fields in galaxy clusters, revealing the impact of galactic mergers on magnetic-field structures and challenging previous assumptions about the efficiency of turbulent dynamo processes in the amplification of these fields.

Galaxy clusters are large, gravitationally bound systems containing numerous galaxies, hot gas, and dark matter...
