Researchers developed a method to produce artificially grown miniature brains — called human brain organoids — free of animal cells that could greatly improve the way neurodegenerative conditions are studied and, eventually, treated. The work offers …

Older people who have little social contact with others may be more likely to have loss of overall brain volume, and in areas of the brain affected by dementia, than people with more frequent social contact, according to a new study.

A new study in mice suggests experimental eye drops may be more effective than injections for treatment of retinal vein occlusion, a major cause of blindness.

New fossil mammal specimens from Caribbean Panama suggest ongoing marine interchange during the final stages of formation of the isthmus connecting North and South America.

A new study reveals that adults with multiple young children engage in significantly less vigorous physical activity compared to those with fewer or no children. The findings have important implications for adults who aspire to be more physically activ…

Two injectable therapies accounted for nearly 100 percent of medications for patients in 2001, but by 2020 that decreased to about 25 percent.

Portable chemical imaging technology can reveal hidden details in ancient Egyptian paintings, according to new research.

The incidence of primary involuntary childlessness, the rate of women seeking treatment for infertility, as well as the success rate of assisted reproductive technology all increased in birth cohorts studied from 1916 to 1975, according to a new study.

Ice Age saber-tooth cats and dire wolves experienced a high incidence of bone disease in their joints, according to new research.

A new mathematical model of UK cat populations suggests that neutering of cats that belong to people not only affects the population dynamics of owned cats, but also affects feral, stray, and shelter subpopulations.

For the first time, a person with an arm amputation can manipulate each finger of a bionic hand as if it was his own. Thanks to revolutionary surgical and engineering advancements that seamlessly merge humans with machines, this breakthrough offers new…

Engineers are training legged robots for future lunar missions that will search for minerals and raw materials. To ensure that the robots can continue to work even if one of them malfunctions, the researchers are teaching them teamwork.

Researchers have developed a model to estimate how much energy the original colonizers of New Zealand expended to maintain their body temperatures on the cold, harrowing ocean journey from Southeast Asia.

A bacterium that causes a disease called scrub typhus — a disease not previously reported in the United States — has been detected in North Carolina, according to a new study.

The same AI technology used to mimic human art can now synthesize artificial scientific data, advancing efforts toward fully automated data analysis.
