Planetary-mass objects (PMOs) are cosmic nomads: they drift freely through space, unbound to any star, and weigh less than 13 times the mass of Jupiter. While they have been spotted in abundance in young star clusters such as the Trapezium Cluster in Orion (Fig. 1), their origin has puzzled scientists. Traditional theories have suggested that they might be failed stars or planets ejected from their solar systems. An international team of astronomers, in collaboration with the University of Zurich (UZH), has used advanced simulations to demonstrate that these enigmatic objects can form directly from the violent interactions of disks around young stars. “PMOs don’t ...

Bacteremia, or blood poisoning, occurs when bacteria overcome the body’s immune defenses. Bacteremia can worsen into sepsis, a condition that accounts for more than 1 in 3 hospital deaths per year. Yet people are routinely exposed to and fight off bacteria from the environment without this deadly series of events occurring. Scientists are trying to figure out exactly how bacteria spread throughout the body to cause systemic infection in the hopes of eventually stopping this process in its tracks. Michael Bachman, M.D., Ph.D., clinical associate professor of pathology and microbiology and immunology at U-M Medical School and former postdoc Caitlyn Holmes, Ph.D., ...

In 1982, the Syrian government besieged the city of Hama, killing tens of thousands of its own citizens in sectarian violence. Four decades later, rebels used the memory of the massacre to help inspire the toppling of the Assad family that had overseen the operation. But there is another lasting effect of the attack, hidden deep in the genes of Syrian families. The grandchildren of women who were pregnant during the siege — grandchildren who never experienced such violence themselves — nonetheless bear marks of it in their genomes. ...

When faced with chronic stress, why do some people develop anxiety and depressive symptoms while others show resilience? A protein that acts as a cannabinoid receptor and is present in the structure controlling exchanges between the bloodstream and the brain could be part of the answer, according to a study published today in Nature Neuroscience. “The protein, called cannabinoid receptor type 1 (CB1), is part of the blood-brain barrier, the dynamic structure that protects the brain by regulating the passage of molecules between the bloodstream and ...
