Some of the blood specimens collected in the United States for the NIH’s All of Us research program starting on January 2, 2020, have antibodies against SARS-CoV-2.

Researchers identify live bacteria in fetal guts, skin, lungs, and placentas that activate memory T cells, indicating that early exposure to microbes could help educate the developing immune system.

Researchers integrated information from 45 protein, metabolite, and immune data points to identify a window two to four weeks before a pregnant person will go into labor.

In Chapter 1, “The Indelible Stamp,” author Melanie Challenger addresses the idea of human exceptionalism.

Since Darwin published his landmark work on natural selection, we’ve understood that we’re animals. But that doesn’t mean we really believe it.

A new analysis of the hand of the 4.4-million-year-old partial skeleton of Ardipithecus ramidus indicates that the human ancestor may have climbed and swung through trees like chimpanzees do.

Researchers determined that when introduced into damaged mouse or donated human livers, these lab-grown tissues could integrate into bile ducts and function normally.

Compared with Zika and cytomegalovirus, the virus that causes COVID-19 appears to have a harder time penetrating the placenta and moving to a woman’s unborn baby.

A selective advantage may have led the modern human Y chromosome to sweep through the Neanderthal population after it was introduced via interbreeding more than 100,000 years ago.

Accumulation of the protein was more likely to be found in the brains of people who slept less well years earlier, according to a new study.

A study of 34 children hospitalized with a coronavirus infection in China reveals that fever and coughing were common, but the type of lesions typically seen in the lungs of adults with COVID-19 were rare.

A tooth and six bone fragments are the oldest confirmed Homo sapiens fossils in Europe.

The inner ear cavity proves to be a useful tool for studying the evolutionary relationships among monkeys, apes, and humans.

In a small trial of deceased volunteers, a Seattle-based company called Recompose demonstrates that its method for “natural organic reduction” of a human body completely breaks down soft tissue.

Genomic information from four children who lived thousands of years ago in what is now Cameroon could shed light on the spread of the Bantu languages and on the history of present-day African populations.

Conflicting results on the existence of new neurons in adults have researchers designing new ways to identify and count neuronal progenitors—and finally get to the bottom of neurogenesis.

It could be a throwback to a mechanism that induces ovulation during sex, researchers propose, but not everyone thinks the results can be extrapolated to people.

After growing in culture for a few months, the mini-brains produced rhythmic neural activity that strengthened over time.
