'It just sounds like a thud': astronomers hear biggest cosmic event since big bang

Researchers believe noise was two black holes colliding around 7 billion years ago, creating a previously unseen class of stellar objectScientists have announced the detection of a signal from a long-ago collision between two black holes that created a new one of a size never seen before.“It’s the biggest bang since the big bang observed by humanity,” said Caltech physicist Alan Weinstein,...

Links among poor sleep, high blood pressure, gut microbiome discovered

Researchers have found associations among disrupted sleep, elevated blood pressure and changes in the gut microbiome. The research aimed to determine whether a 28-day period of disrupted sleep changed the microbiota in rats. The researchers also sought to identify biological features associated with undesirable arterial blood pressure changes.

How mechanical forces nudge tumors toward malignancy

Researchers studying two forms of skin cancer identified a long-overlooked factor determining why some tumors are more likely to metastasize than others: the physical properties of the tissue in which the cancer originates. The findings might set the stage for new ways to monitor and treat the diseases in the future.

New treatment for drug-resistant bacterial infections

A new antibacterial agent that has been engineered to essentially hide from the human immune system may treat life-threatening MRSA infections. A new article provides details on the agent, which is the first lysin-based treatment with the potential to be used multiple times on a single patient, making it ideal to treat particularly persistent drug-resistant and drug-sensitive infections.

Newly identified gene grants tomatoes resistance to bacterial speck disease

Bacterial speck disease, which reduces both fruit yield and quality, has been a growing problem in tomatoes over the last five years. Because the culpable bacterium, Pseudomonas syringae, prefers a cool and wet climate, crops in places such as New York State have been particularly susceptible. Researchers have uncovered the first known gene to impart resistance to a particular strain of the...

Many forests scorched by wildfire won't bounce back

A study of 22 burned areas across the Southern Rocky Mountains found that forests are becoming less resilient to fire, with some converting to grasslands after burning. By 2050, as little as 3.5% to 6.3% of Douglas fir and ponderosa pine forests in the region will be suitable for recovery post-fire, the study found.
