Chemists reveal the first path for the inclusion of selenium in natural products

Leave a Comment / Science / By

Princeton Chemistry researchers have discovered a biosynthetic pathway that incorporates selenium into small microbial molecules, marking the first time such atoms have been discovered in natural products and opening new avenues in selenobiology. Research also strongly suggests that selenium, an essential trace element in all realms of life, may play a more important biological role …

Researchers at Johns Hopkins University have devised self-assembling nano-scale pipes that are leak-free and can be used to install plumbing in our cells. The nanotubes, visible as thin green lines, attach themselves to the cells. Image credits Schulman Lab / Johns Hopkins University. Leak-free piping is something anyone who has ever had a plumbing problem …

Tumors: not just a backup: the double specificity of UBA6

Leave a Comment / Science / By

The ubiquitylation of target proteins is one of the most important post-translational modifications and plays essential roles in numerous cellular processes. Ubiquithylation is performed by a sequential enzyme cascade of E1 activating enzymes, E2 conjugating enzymes and E3 binding enzymes. For many years it was thought that UBA1 was the only E1 enzyme that activates …

A surprising discovery reveals the slowing of controlled continental plate movement in the times of Earth's largest volcanic events

A surprising discovery reveals the slowing of controlled continental plate movement in the times of Earth’s largest volcanic events

Leave a Comment / Science / By

Scientists have shed new light on the timing and probable cause of major volcanic events that occurred millions of years ago and caused climatic and biological upheavals that resulted in some of the most devastating extinction events in Earth’s history. Surprisingly, the new research, published today in the leading international journal Science Advances, suggests that …

SpaceX Starship Prototype Belches Superhot Debris, Causes Literal Dumpster Fire

SpaceX prototype spacecraft burps super hot debris, causing a real fire in the dumpster

Leave a Comment / Science / By

On Thursday, SpaceX performed a static fire test of a Starship prototype rocket, in which all six raptor engines were engaged. The eight-second test seemed to be fine, aside from the troubled fire that followed. The prototype of spaceship 24 is currently being tested at SpaceX’s Starbase facility in Boca Chica, Texas. SpaceX is preparing …
