A type of aggressive, treatment-resistant brain tumor has a distinct population of immune cells that support its growth, according to new research.

Women who have experienced pregnancy complications have an increased risk of cardiovascular disease. Now, a new study shows that sisters of women with complicated pregnancies are also at higher risk, even if they had uncomplicated pregnancies. The findings suggest that genes and shared environmental factors may influence the association between pregnancy complications and cardiovascular disease risk.

New research using publicly-shared DNA barcodes and citizen science images have provided new evidence on the establishment and spread of a biological control agent used for the control of the major invasive shrub Lantana camara.

Nerve cells have amazing strategies to save energy and still perform the most important of their tasks. Researchers found that the neuronal energy conservation program determines the location and number of messenger RNA (mRNA) and proteins, and differs depending on the length, longevity and other properties of the respective molecule.

Researchers have analyzed the soft tissue from a fossilized plesiosaur for the first time. The results show that the long-necked marine reptile had both smooth and scaly skin. This was likely so it could both swim rapidly and move along rough seabeds.

Embedded counseling services are becoming increasingly common in veterinary medical programs, but their effectiveness has not historically been measured. A new study revealed that these programs may not only enhance access to mental health care but also lead to significant reductions in psychological distress among veterinary trainees.

Researchers have achieved total chemical synthesis of the psychoactive compound ibogaine and its analogs from pyridine. The discovery will make it easier to explore the therapeutic possibilities of ibogaine.

New research finds some baleen whale species call at such deep frequencies that they’re completely undetectable by killer whales, which cannot hear sounds below 100 hertz. These also tend to be the species of baleen whales that flee in the face of attack from killer whales.

An international team of researchers has shown that countless tiny ice quakes take place in one of Greenland’s mightiest ice streams. This finding will allow the flowing of the ice sheet and associated changes in sea level to be estimated more accurately.

Researchers have unveiled the precise brain mechanisms that enable animals to overcome instinctive fears. The study in mice could have implications for developing therapeutics for fear-related disorders such as phobias, anxiety and post-traumatic stress disorder (PTSD).
