Younger and middle-aged men are the loneliest they’ve ever been in generations, and it’s probably going to get worse. This is not my typical rosy view of relationships but a reality nonetheless. Over the last 30 years, men have become a larger portion of that growing group of long-term single people. And while you don’t actually need to be in a relationship to be happy, men typically are happier and healthier when partnered.

Jumping spiders rapidly move their eyes and twitch during rest, suggesting they have visual dreams, never before observed in arachnids.

Unlike all other studied primates, humans lack vocal membranes. That lets humans produce the sounds that language is built on, a new study suggests.

New research describes food systems designed not by the logic of growth such as efficiency and extraction, but by principles of sufficiency, regeneration, distribution, commons, and care. It argues that food systems can instead be the foundation of healthy communities, ecologies and economies.

There isn't currently a Lyme disease vaccine on the U.S. market. Researchers are hoping to change that.

PHYSICAL SCIENTISTS SEEM to find the phenomenon of chaos everywhere: in the orbits of planets, in weather systems, in a river’s swirling eddies. For nearly three decades, ecologists considered chaos in the living world to be surprisingly rare by comparison. A new analysis, however, reveals that chaos is far more prevalent in ecosystems than researchers thought.

More than half of human diseases caused by pathogens have been aggravated by hazards associated with climate change, study finds

A new study shows weekend warriors have a comparable mortality rate to those who exercise daily.

When you are facing stressful situations with another person, is it better for them to stay calm or be stressed out alongside you? Though it may seem intuitive that it is preferable for one party to remain calm, a study published in Frontiers in Psychology suggests that when the stress is validated, reactivity can decrease, but only for women.

African Americans are almost three times as likely to be vegan than white Americans.

Regardless of disease severity, people who have lingering smell loss after covid-19 are more likely to have cognitive problems than those who regain or never lose their sense of smell  

A recent study has found that children who watch TV as part of their bedtime routine get less sleep, experience more sleep problems, and exhibit more attention problems and aggressive behavior six months later.

The unexpected discovery of a 16th-century horse tooth in modern-day Haiti has provided credence for an age-old folk story about the origin of feral horses on an island off Maryland and Virginia.

A team of researchers with the University of Oslo has found evidence that suggests human fleas and lice, not rodents, were behind the spread of the plague that killed millions of people over the course of several centuries. In their paper published in Proceedings of the National Academy of Sciences, the group reports using mathematical models from mortality records to demonstrate how the plague would have spread under different scenarios and what they found by doing so.

Microbiome-related metabolites, blood sugar, and inflammation appear more important than blood cholesterol in mediating heart disease due to meat intake.

Researchers who previously revived some brain cells in dead pigs succeeded in repeating the process in more organs.

For people with mild cognitive impairment, stretching or other light exercise for just 2 hours a week can prevent further cognitive decline

Eating Jarlsberg cheese may help to prevent bone thinning and stave off osteoporosis, research suggests. Jarlsberg is a mild cheese made from cow’s milk, with regular holes that mean it is classified as a Swiss-type cheese, although it originates from Norway. It is rich in vitamin K2, which has previously been found to improve bone health.

In 1963, the mathematician Roy Kerr found a solution to Einstein’s equations that precisely described the space-time outside what we now call a rotating black hole. (The term wouldn’t be coined for a few more years.) In the nearly six decades since his achievement, researchers have tried to show that these so-called Kerr black holes are stable.

Compensating for the lost time may prove challenging for scientists.
