How Galaxies Die: New insights into the Quenching of Star Formation

A new theory explains how black holes grow as a function of galaxy mass and eventually quench star formation in their host galaxies. The images on this graph, taken by the Sloan Digital Sky Survey, are of nearby galaxies at the present era chosen to represent galaxy evolution. The graph shows how the evolution of small, dense galaxies differs from that of larger, more diffuse galaxies. The denser galaxies have larger black holes for their mass and therefore quench sooner, at a lower mass, whereas the more diffuse galaxies have smaller black holes for their mass and must grow more before quenching occurs. See larger image. (Credit: Sandra Faber/Sofia Quiros/SDSS)

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive ga...

Peptide-derived nanoparticle shows promise in lab. Researchers at the University of Illinois at Chicago have developed a new drug that prevents blood clots without causing an increased risk of bleeding, a common side effect of all antiplatelet medications currently available.

A new study published in the journal Science Translational Medicine describes the drug and its delivery mechanisms and shows that the drug is also an effective treatment for heart attack in animal models.

Xiaoping Du, UIC professor of pharmacology and regenerative medicine at the College of Medicine, led ...

New Cobalt-Free Lithium-ion Battery Reduces Costs Without Sacrificing Performance

Product – Powder[2] copy
These powder samples will be fabricated to become the cobalt-free cathode.

Researchers say they’ve cracked the code to a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening the door to reducing the costs of producing batteries while boosting performance in some ways.

For decades, researchers have looked for ways to eliminate cobalt from the high-energy batteries that power electronic devices, due to its high cost and the human rights ramifications of its mining. But past attempts haven’t lived up to the performance standards of batteries with cobalt.

Researchers from the Cockrell School of Engineering at The University of Texas at Austin say they’ve cracked the code to a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening th...

ESA/NASA mission returns first data, snaps closest pictures of the Sun. The first images from Solar Orbiter, a new Sun-observing mission by ESA and NASA, have revealed omnipresent miniature solar flares, dubbed ‘campfires’, near the surface of our closest star.

According to the scientists behind the mission, seeing phenomena that were not observable in detail before hints at the enormous potential of Solar Orbiter, which has only just finished its early phase of technical verification known as commissioning.

“These are only the first images and we can already see interesting new phenomena,” says Da...
