Psychedelics may find new, legitimate roles in treatment for anxiety, depression, stress disorders, addiction, and other mental and behavioral health problems. But ensuring they do requires developing rigorous, standardized methods to study and apply t…

A challenge in materials design is that in both natural and humanmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical explanations for this phenomenon for some specific materials, a general u…

The first large-scale trial to test the long-term effects of a cocoa flavanol supplement to prevent cardiovascular disease offers promising signals that cocoa flavanols could have protective cardiovascular effects.

Stroke can have many causes. An atherothrombotic stroke is caused by a clot that forms from plaques that build up within blood vessels in the brain. A new study suggests that people who have this type of stroke who also have higher levels of triglyceri…

In mice, social ranking in a group was linked to the results of competition, and certain neurons in the brain stored this social ranking information to inform decisions. Manipulating the activity of these neurons could increase or decrease an animal’s …

A small preliminary study has shown that a blood test may identify risk of stillbirth and placentitis in pregnant individuals who have had COVID-19. The finding builds on another study with similar results and could have implications in how physicians …

Current policies for guaranteeing food security emphasize the importance of farmland, but forests play critical roles as well. Forested areas can help communities that rely on wild foods to diversify their diets and meet their nutritional needs, accord…

An inhalable ‘aerogel’ loaded with DNA that encodes for the SARS-CoV-2 spike protein successfully induces an immune response against COVID-19 in the lungs of mice, according to new research. The team said its aerogel could be used to create an inhalabl…

New research has linked phthalates, commonly called the ‘everywhere chemical,’ to higher incidence of specific childhood cancers.

A research team has discovered novel metabolic mechanisms that contribute to how ovarian cancer escapes from immune attack, and how combination therapies can exploit these pathways to improve ovarian cancer treatment.

Individual Candida albicans yeast strains in the human gut are as different from each other as the humans that carry them, and some C. albicans strains may damage the gut of patients with inflammatory bowel disease (IBD), according to a new study. The …

Raising taxes on tobacco is associated with a reduction in neonatal and infant mortality, according to an analysis of 159 countries.

The American College of Cardiology has issued an expert consensus decision pathway for the evaluation and management of adults with key cardiovascular consequences of COVID-19. The document discusses myocarditis and other types of myocardial involvemen…

A massive release of greenhouse gases, likely triggered by volcanic activity, caused a period of extreme global warming known as the Paleocene-Eocene Thermal Maximum (PETM) about 56 million years ago. A new study now confirms that the PETM was preceded…

A study shows that 3D ultrasound incorporating new matrix technology is reliable, accurate, and faster than previous methods for the assessment of plaque volume in the carotid and femoral arteries.

A team of scientists has constructed a robot leg that, like its natural model, is very energy efficient. BirdBot benefits from a foot-leg coupling through a network of muscles and tendons that extends across multiple joints. In this way, BirdBot needs …
