An unexpected, and novel, target for prostate cancer – our biological clock

PHILADELPHIA – Our biological or circadian clock synchronizes all our bodily processes to the natural rhythms of light and dark. It’s no wonder then that disrupting the clock can wreak havoc on our body. In fact, studies have shown that when circadian rhythms are disturbed through sleep deprivation, jet lag, or shift work, there is […]

Gravity Data Reveal Unexpected Antarctic Ice Variations

As more coastal communities face the looming threat of rising sea levels, it’s more important than ever to accurately predict changes in one of the greatest potential sources of sea level rise—the melting of Antarctica’s massive ice sheet. Recently, scientists analyzed nearly 2 decades’ worth of data from sensitive NASA satellites documenting mass […]

Research chemists discover cells’ unexpected clean-up techniques — ScienceDaily

In a new paper with results that senior author Eric Strieter at the University of Massachusetts Amherst calls “incredibly surprising,” he and his chemistry lab group report that they have discovered how an enzyme known as UCH37 regulates a cell’s waste management system. Strieter says, “It took us eight years to figure it out, and […]

Ancient crocodiles’ family tree reveals unexpected twists and turns — ScienceDaily

Scientists probing a prehistoric crocodile group’s shadowy past have discovered a timeless truth — pore over anyone’s family tree long enough, and something surprising will emerge. Despite 300 years of research, and a recent renaissance in the study of their biological make-up, the mysterious, marauding teleosauroids have remained enduringly elusive. Scientific understanding of this distant […]

DNA in fringe-lipped bat feces reveals unexpected eating habits — ScienceDaily

Feces is full of secrets. For scientists, digging into feces provides insights into animal diets and is particularly useful for understanding nocturnal or rare species. When animals eat, prey DNA travels all the way through animal digestive tracts and comes out again. Feces contains very precise information about the prey species consumed. At the Smithsonian […]

FDA Finds Unexpected Antibiotic Resistance Genes in ‘Gene-Edited’ Dehorned Cattle

gene-edited polled calves

By Jonathan Latham, PhD and Allison Wilson, PhD Gene-editing is seen by many as the ultimate in precision breeding. Polled cattle, whose horns have been genetically removed, have been presented as exemplars of this–a socially beneficial use of precise genome engineering. Such hornless cattle were produced in 2016 by Recombinetics, Inc., of St. Paul, Minnesota, […]
