Diet quality among adolescents in the United States is among the worst across all age groups, putting young people at risk for heart attack, stroke, and diabetes, among other cardiometabolic diseases later in life, according to a new study. The researc…

Infusions of potentially therapeutic cells derived from the heart are safe for people with pulmonary arterial hypertension, a form of high blood pressure that occurs in the blood vessels of the lungs and typically affects middle-aged women, according t…

For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and stable laser sources that would be useful in a variety …

Researchers successfully tested a simple intervention that could unlock greater anti-tumor power in therapies that use T cells — an approach known as ‘cell-based therapy,’ which uses specially designed T cells to fight cancer. The team has proven an e…

This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it’s likely been spoil…

Researchers have created a complete cell atlas of a whole mammalian brain. This atlas serves as a map for the mouse brain, describing the type, location, and molecular information of more than 32 million cells and providing information on connectivity …

Researchers have shown that the effects of wildfires are not limited to terrestrial ecosystems. Aquatic ecosystems are also undergoing rapid changes. The study found that fire debris transforms lakes and other aquatic ecosystems, with implications for …

Protein-splitting enzymes play an important role in many physiological processes. Such proteases are generally present in an inactive state, only becoming activated under certain conditions. Some are linked to diseases like infections or cancer, making…

A type of cell that plays a crucial role in tissue repair after a heart attack may also inadvertently be why cutting-edge cell therapies cause an increased risk of rhythm disorders, according to a new study. Researchers hope the findings could open up …

Researchers developed machine-learning models to predict visual acuity in patients with high myopia. A cohort study of 967 patients was used to evaluate the models. The results show that a regression model accurately predicts visual acuity at 3 and 5 y…

Substance use disorder may be linked to more deaths from infective endocarditis among people ages 25-44, finds a new study.

A protein that helps generate the force needed for single cells to move works differently in cells moving in groups, a new study shows.

Apple watches have some advantages over traditional ways of diagnosing cardiac arrythmias in children but need more validation, finds a new study.

Even in the precipitation-heavy Pacific Northwest, more frequent heatwaves are threatening a key source of water supply. A Washington State University study that intended to look at snow melting under a single, extreme event, the 2021 ‘heat dome,’ inst…

Do epigenetic changes cause type 2 diabetes, or do the changes occur only after a person has become ill? A new study provides increased support for the idea that epigenetic changes can cause type 2 diabetes.

The transition to a society without fossil fuels means that the need for batteries is increasing at a rapid pace. At the same time, the increase will mean a shortage of the metals lithium and cobalt, which are key components in the most common battery …

Individuals infected with COVID-19 are also at an increased risk of suffering from heart rhythm disturbances, such as atrial fibrillation, according to a new study.

Strong precipitation may cause natural disasters, such as floodings or landslides. Global climate models are required to forecast the frequency of these extreme events, which is expected to change as a result of climate change. Researchers have now dev…

Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity inf…

One-letter difference in our DNA determines whether BCG vaccine provides good protection against tuberculosis or not. Researchers have elucidated how that one letter difference affects the activation and deactivation of the immune system. The discovery…
