Instead of forming far out where comets took shape, Bennu may have emerged near the young solar system’s water-ice line, where Jupiter helped shape the mixture of dust that built the asteroid. Understanding exactly how the planets formed 4.5 billion years ago requires looking at material that has hardly changed since the solar system was […]
NASA’s Perseverance Rover Finds Mars Had a Far More Complicated Water History Than Expected
A new study suggests that Jezero Crater’s mysterious “Margin Unit” records a surprisingly complicated history involving ancient lakes, groundwater, and heated fluids moving through the Martian subsurface. When NASA’s Perseverance rover arrived at the inner rim of Mars’ Jezero Crater in September 2023, scientists expected to encounter sedimentary rock. The region, known as the “Margin […]
Noninvasive Cancer Treatment Looks Safe, yet 11% of Patients Died Within a Month
Histotripsy appears well tolerated procedurally, but real-world outcomes suggest that choosing the right patients may be just as important as performing the treatment safely. A patient can undergo treatment for a liver tumor without an incision, avoid a hospital stay, and tolerate the procedure with few immediate complications. But for people with advanced cancer, safely […]

Why Do Muscles Weaken With Age? Scientists May Have Found an Important Missing Piece
A newly identified breakdown in nerve-muscle communication may help explain age-related weakness. Muscles do not weaken with age simply because they get smaller. New research suggests that part of the problem may lie in the electrical signals that tell them when to contract. Scientists at the University of Missouri found that communication between nerves and […]
MIT’s Paper-Thin Swimming Robot Is Powered by Living Muscle
MIT engineers created a paper-thin swimming robot that uses light-controlled living muscle cells to move and steer through water. Navigating delicate underwater ecosystems requires a gentle physical touch that conventional metal and plastic motors cannot provide. Engineers trying to build machines soft enough for these environments often turn to living tissue, constructing biohybrid machines powered […]
