Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated from each other, even if they control the same gene, and switch it on in different parts of the body. A recent study challenges this idea. The findings are also important because... Read more ›

In an era of dwindling glaciers, Southern Patagonia has managed to hold on to a surprising amount of its ice. But, a new study suggests that this protective effect might be pushed up against its limits soon. Read more ›

A massive collision of galaxies sparked by one travelling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth's most powerful telescopes. The dramatic impact was observed in Stephan's Quintet, a nearby galaxy group made up of five galaxies first sighted almost 150 years ago. It sparked an immensely powerful shock akin to a 'sonic boom from a jet fighter' --... Read more ›

Researchers have analyzed the entire mouse intestine, mapping gene expression and cell states and location in the healthy gut and in response to perturbations such as inflammation. They identified tight regulation of cell types and states in different regions of the organ, as well as a unique segment of the colon that is controlled by immune signals. The findings reveal the surprising adaptability and resilience of the intestine to perturbations... Read more ›

Adolescents who snore frequently were more likely to exhibit behavior problems such as inattention, rule-breaking, and aggression, but they do not have any decline in their cognitive abilities, according to a new study. This is the largest study to date tracking snoring in children from elementary school through their mid-teen years and it provides an important update to parents struggling with what medical measures to take to help manage snoring...

Hidradenitis suppurativa (HS) is an immune disease that affects up to 4% of the global population and causes painful, recurring skin lesions and inflammation, primarily in the folds of the skin. It commonly affects women of African American descent. Read more ›

A new study shows that the oceans were less cold in the early 20th century (1900--1930) than previously thought. During this period the ocean appears too cold due to the way some measurements were taken. This makes global ocean surface temperature measurements during this period inconsistent with both land air temperatures and palaeoclimatic data and the differences between land and ocean are larger than shown in climate models.

After severe heart failure, the ability of the heart to heal by forming new cells is very low. However, after receiving treatment with a supportive heart pump, the capacity of a damaged heart to repair itself with new muscle cells becomes significantly higher, even higher than in a healthy heart.

Axions are the most likely candidate for enigmatic dark matter that dominates the universe. Astrophysicists are searching for evidence of high-mass axions produced during supernovae. Scientists propose that a quick way to find these axions is to look for a gamma ray burst coincident with a neutrino burst from a nearby core collapse supernova. But we need a fleet of gamma ray telescopes to insure we capture these rare events. Read more ›

Archaeology studies the human past through the excavation of things people made and used thousands of years ago -- from architecture to objects like pottery bowls and animal bones from meals. Although many excavation projects create digital 3D models of what they uncover, archaeologists need new ways to meaningfully use those data. Some projects share 3D models with the public as tourism and teaching tools -- one may have recently... Read more ›
