In many animal tissues, stem cells continually divide to create new cells that replace old or damaged ones. However, this capacity requires strict regulation, as uncontrolled stem cell proliferation can disrupt tissue homeostasis ...

Wearable health monitors have grown increasingly capable, but most are still limited by the fact that tracking different types of body signals requires separate sensors, each with its own circuitry and patch of skin. That ...

Evolution is a fact of life. So much so that even the theory of evolution is evolving. Lately, a centuries-old discredited idea has been making a strong comeback. It helps us explain scientific observations that, according ...

An international team, including Kumamoto University and its partner institutions, has found severe flood risks and high climate-adaptation costs for U.S. small rivers.

A growing body of scientific evidence confirms what many of us know innately—spending time in nature is good for us. It not only lowers stress and depression, it strengthens immunity, boosts cognitive performance, promotes ...

Protecting sensitive, precision-timed computing systems requires understanding the nature of cyberthreats. So researchers from Washington State University teamed up with experts at the University of Colorado Colorado Springs ...

Nanocarbons are molecular-scale carbon structures considered to be the building blocks for next-generation materials. Until now, scientists have built them by fusing small, flat carbon molecules together at their edges. Modifying ...

Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries, where they are helping to reduce reliance on electricity generated from fossil fuels. While most solar cells used today ...

University of Liverpool researchers have identified that hospital admissions in England for ectopic pregnancy (when a fertilized egg implants outside the womb) have been increasing since 2021, with more than twice as many ...

While headlines warn that AI could unleash future biological threats, the technology also offers our best defense: a way to anticipate viral evolution and stress-test treatments. Rather than waiting for SARS-CoV-2 to mutate ...

Complex simulations—the most intricate of their kind to date—carried out by an international research team led by scientists at Heidelberg University's Institute for Physical Chemistry, have revealed how water governs the ...

A naturally abundant plant material best known for giving trees and crops their strength may one day help repair broken bones, according to a new study led by postdoctoral researcher Dr. Srinath Palakurthy and Professor Rivka ...
