Bowhead whales can live more than 200 years. Tiny shrews barely make it a year. Some sea sponge species are over 15,000 years old. That gap raises a straightforward question: what’s different at the biological level? Instead of hunting for a single “longevity gene,” researchers looked for patterns across sets of related genes that might scale up in species with …

The Earth is constantly receiving space signals that contain vital information about extremely energetic phenomena. Among the most peculiar are brief pulses of extremely high-energy radio waves, known as fast radio bursts (FRB). Astronomers compare them to a powerful lighthouse that shines for milliseconds in the middle of a rough, distant sea. Detecting one of these signals is an achievement …

Scientists at the DIII-D National Fusion Facility are investigating a different approach to tokamak operation that has yielded promising results for the design of future fusion power plants.  Recent experiments have demonstrated that a plasma configuration known as “negative triangularity” can achieve the high-performance conditions necessary for sustained fusion energy, while also addressing a critical challenge related to heat management …

The billionaire owners of Space X and Blue Origin have competing visions of a space-based future. Elon Musk wants a self-sustaining settlement on Mars as a backup for humanity in case the Earth gets destroyed. Jeff Bezos wants us to move heavy industry and all polluting industries to space to save Earth’s climate, and envisions a trillion humans living in …

In 2016, geologists discovered an extraordinary phenomenon deep beneath a Canadian mine—a water source trapped in rock for over 2.6 billion years. This discovery, published in Nature, has provided unprecedented insights into the survival of ancient microbial life and the water’s ability to exist without exposure to sunlight for such vast periods of time. What’s more, the water is still …
