They raid compost bins, outsmart latches and sometimes look gleeful doing it. A new study in Animal Behaviour suggests raccoons may not just be opportunistic—they may be genuinely curious.
Asteroids are some of the oldest objects in the solar system: leftovers from the chaotic time when planets were assembling from dust and rock. They're time capsules, preserving clues about what the early solar system was like, and, ultimately, what the building blocks of
An international team of researchers has modified a probiotic yeast to make it safer for use by immunocompromised people, older adults and infants. Testing in an animal model found that the modified yeast is less likely to cause infection than unmodified strains of the same
Exercise normally boosts the body’s ability to use oxygen, a key marker of health and longevity — but high blood sugar can block that benefit. Researchers found that a ketogenic diet helped mice normalize blood sugar and dramatically improved how their muscles responded to
Somewhere in the North Atlantic, more than a kilometer beneath its surface, a cold-water coral reef stretches across an unnamed seamount. Despite never appearing on a chart, this underwater forest has existed for centuries, growing a centimeter or two each year.
Global levels of physical activity have not improved over the past two decades, despite widespread policy development and adoption, and large disparities persist across gender and socioeconomic groups. The findings from three papers published in Nature Medicine and Nature
The search for materials that can conduct electricity at room temperature without losing energy is one of the greatest and most consequential challenges of modern physics: loss-free power transmission, more efficient motors and generators, more powerful quantum computers,
Drug discovery is like molecular Tetris. Chemists snap atoms together, adjusting the pieces until everything fits, and suddenly, a molecule makes a promising new medicine. Normally, creating better molecules consumes huge amounts of time and money. In a new study appearing in
Controlling light with light is a long-sought goal for computing and communication technologies. Achieving this capability would allow optical signals to be processed without converting them into electrical signals, potentially enabling faster and more energy-efficient devices.
