Every day we encounter circumstances we consider wrong: a starving child, a corrupt politician, an unfaithful partner, a fraudulent scientist. These examples highlight several moral issues, including matters of care, fairness and betrayal. But does any…

An analysis of data from a long-running study of more than 11,000 adults from four diverse communities in the United States has found that adults who had high blood pressure while both seated upright and lying supine (flat on their backs) had a higher …

An analysis of electronic health records for more than 60,000 adults in the United States found that systolic, or top-number, blood pressure rose slightly during the winter compared to summer months. The health records were of adults being treated for …

Children of a parent with alcohol or drug use disorder have a greater risk of intellectual disability, even if the problem only lies with the father, researchers report. According to the study, preventive measures should be directed at both parents.

A new study shows that counter to public perception, positive beliefs about the world are a poor indicator of a person’s background.

An international consortium of scientists is using an unprecedentedly large database of canine DNA to take an unbiased look at how our furry friends evolved into the various breeds we know and love.

A new artificial intelligence tool can help people with Parkinson’s disease remotely assess the severity of their symptoms within minutes. While expert neurologists performed slightly better than the AI model, the AI model outperformed the primary care…

Millions of Americans have inflammatory bowel disease (IBD), which occurs in one of two forms: Crohn’s disease or ulcerative colitis. Though the two have similar symptoms, they require different treatment strategies, and tests to distinguish between th…

Researchers have successfully created chimeric embryos containing a combination of human and pig cells. When transferred into surrogate pig mothers, the developing humanized kidneys had normal structure and tubule formation after 28 days. This is the f…

Between 1840 and 1867, thousands of enslaved Africans who had been ‘liberated’ from slave ships intercepted by the British Royal Navy were taken to the South Atlantic island of St Helena. But little is written in history books or otherwise known about …

In many animals, including ants, the blood-brain barrier (BBB) ensures normal brain function by controlling the movement of various substances in and out of the brain. Now, researchers have made the unexpected discovery that the BBB in carpenter ants p…

New research shows that socio-economic factors play a larger role in migration than climate.

Scientists are reporting results from a Phase I trial in an area of promising research for Alzheimer’s disease — cellular senescence.

Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly …

By adding synergistic self-adjuvanting properties to Covid-19 RNA vaccines, researchers showed they could significantly boost the immune response generated in mice.

Genetic manipulation of a puzzling, miniscule bacteria that has lived in human mouths at least since the Middle Stone Age is elucidating the genes needed for its unusual lifestyle. These Patescibacteria in the human oral microbiome reside on the surfac…

Researchers have developed a new approach that slashes the land and time needed to extract lithium from brine, which could dramatically expand access to the critical mineral.

Researchers reveal for the first time that high blood sugar levels in type 2 diabetes can play a causal role in lung disorders.

New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.

In many neurodegenerative disorders, abnormal proteins progressively aggregate and propagate in the brain. But what comes first, aggregation or propagation? Researchers from Japan share some new insights about the mechanism involved in Parkinson’s dise…
