Mechanical hearts spur some regeneration in dormant parts of failing hearts, according to a pilot study that shows promise for developing regenerative heart therapies.

An international team has discovered novel properties of the protein Gasdermin B that promotes repair of cells lining the gastrointestinal tract in people with chronic inflammatory disorders like Crohn’s disease and ulcerative colitis.

Researchers have been monitoring wastewater on the UC Davis campus and in the city of Davis for COVID-19 through the Healthy Davis Together program. A new article reviews their experiences and the advantages and limitations of wastewater testing as a p…

Unprecedented mass loss from three Antarctic glaciers could signal global climate trouble ahead, a researcher warns. A multinational collaboration is using an advanced remote imaging system to document the Pope, Smith and Kohler glaciers with clarity a…

At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from magma rising from belowground force the land apart? Or is a rift just a rip, created ma…

Individual aspects of poor sleep can be detrimental to heart health. But if you combine them, the risk of heart disease can increase by as much as 141 percent.

People with post-traumatic stress disorder (PTSD) and/or bipolar disorder living in rural areas engaged well with telehealth-based telepsychiatry, though the ones who received local psychotherapy completed more sessions.

An international team has used ancient DNA to rewrite the history of the Scottish Orkney islands to show that Orkney actually experienced large-scale immigration during the Early Bronze Age, which replaced much of the local population.

The fear predators inspire can itself reduce prey population growth rates; thereby conclusively establishing that focusing solely on the number of prey predators directly kill and failing to additionally consider fear, as conventionally done, risks dra…

When Hurricane Maria slammed into Puerto Rico in September 2017 as a high-end category 4 storm, it left in its wake the largest catastrophe in the history of the island. Along with the human toll, the devastation impacted all the island’s wildlife, inc…

New research discovered that the fungus Rhizopus fights back against soil predators and human immune cells by partnering with a bacteria called Ralstonia in a two-way partnership.

Very little of the plastic water bottles, milk jugs and yogurt cups we use gets recycled. But chemists now describe a radical method they used to transform tossed out plastic into a tougher, stronger material commonly used for food packaging. Through ‘…

In many mammals including humans, the placenta invades the wall of the uterus during pregnancy in the same way that cancer cells invade surrounding tissues. Using genomic sequences and gene expression information, researchers were able to predict speci…

Researchers report that a prospective study of 14 infants and children demonstrated that convalescent plasma — a blood product collected from patients recovered from infections with the coronavirus (SARS-CoV-2) that causes COVID-19 — was safe in high…

An imprinted gene associated with development of non-alcoholic fatty liver disease (NAFLD) is switched on in mice who nurse from mothers with metabolic syndrome, even when those mice are not biologically related.

Biologists from Southern and Baja California have published the first major account of the amphibian disease chytridiomycosis in the Mediterranean region of Baja California. Their results indicate that the disease is more prevalent on the peninsula tha…

Critically ill COVID-19 patients on a mechanical ventilator or extracorporeal membrane oxygenation (ECMO) lived more often when randomized to receive baricitinib. Doctors call this drug ‘bari,’ and receiving the pill once a day for up to 14 days yielde…

Researchers have developed a new protocol for monitoring acute lymphoblastic leukemia (ALL), the most common cancer in children, to inform more effective treatment strategies and detect disease recurrence. The personalized mediator probe PCR (MP PCR) u…

An analysis of federal health data indicates that people who have had COVID-19 are at increased risk of developing cardiovascular complications within the first month to a year after infection, according to researchers.

During the first wave of the pandemic, patients with COVID-19 who experienced strokes caused by blockage of blood flow to brain tissues were more likely to die or have serious complications compared with non-infected stroke patients, a study finds.
