PhysicsBerkeley Study Finds Hula Hooping Runs on Your Shin and Foot, Overturning 20 Years of Thinking
Sensors and nonlinear math show the hoop's orbit and wobble are coupled, not controlled separately, with the ankle and foot playing a bigger role than expected.
ScienceBerkeley Bolted 48 Camera Chips Into One Microscope and Hit 25.2 Billion Pixels a Second
The instrument resolves 3-micron detail across 5 square centimeters at 120 frames per second — a combination of resolution, field of view and speed that optical engineers have treated as a fixed trade-off for decades.
ScienceBerkeley Scientists Found Two Human Ancestors Nobody Has Ever Seen — Hiding in Our Own DNA
A new method called TRACE detected a "ghost" lineage that split from us 800,000 years ago and left about 1% of the modern genome, plus a second, far older population inherited through the Denisovans.
ScienceScientists Map the Brain Circuit Where Deep Sleep Triggers the Body's Repair Hormone
A UC Berkeley team traced how non-REM sleep unleashes growth hormone — and found the hormone loops back to nudge the brain awake, a self-balancing system tied to muscle, fat and memory.
PhysicsA Strange Cosmic 'Chirp' Reveals the Birth of a Magnetar for the First Time
Watching a distant supernova flicker four times in a quickening rhythm, astronomers caught the moment an ultra-magnetic neutron star switched on — and saw Einstein's relativity at work in an exploding star.
ScienceMicrobe Breaks Biology's 60-Year Rule: The Same DNA 'Stop' Signal Can Now Mean Two Different Things
UC Berkeley researchers discover that an ancient archaeon reads the universal stop codon ambiguously, sometimes inserting an amino acid instead of halting protein synthesis — with implications for treating 10% of all inherited diseases.
ScienceScientists Discover Sleep Circuit That Controls Growth Hormone and Builds Muscle
UC Berkeley researchers map brain pathways showing how deep sleep actively rebuilds the body through hormone surges that fuel muscle growth and fat burning.
