A blood test that can accurately detect when someone has not slept for 24 hours has been developed.

The COVID-19 virus can persist in the blood and tissue of patients for more than a year after the acute phase of the illness has ended, according to new research that offers potential clues to why some people develop long COVID.

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest objects in the universe.

Researchers have uncovered blood-based markers linked with healthy and rapid aging, allowing them to predict a person’s biological age — how fast a person’s cells and organs age regardless of their birth date.

New research describes the science behind a promising technique to treat infertility by turning a skin cell into an egg that is capable of producing viable embryos. The technique could be used by women of advanced maternal age or for those who are unab…

Insights into the workings of an immune cell surface receptor, called PD-1, reveal how treatments that restrict its action can potentially be strengthened to improve their anticancer effect, a new study shows. The same findings also support experimenta…

Researchers have discovered a mechanism steering the evolution of multicellular life. They identified how altered protein folding drives multicellular evolution.

A team deciphers complicated mechanism underlying genetic diversity.

Smaller class sizes in schools are failing to increase the resilience of children from low-income families, according to a new study.

A research team discovers universal mechanism that leads to adhesion hysteresis in soft materials. Through a combination of experimental observations and simulations, the team demonstrated that roughness interferes with the separation process, causing …

Biologists present groundbreaking research shedding new light on the evolution of social bonds and cooperation among group-living animals.

Researchers have shown that sleep enhances the migratory potential of T cells toward lymph nodes.

Water determines life: humans are three-quarters water. An international research team has now discovered how water also determines the structure of the material that holds us together: collagen. The researchers now elucidate the role of water in the m…

A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
