Unitree Robotics wants to raise about $900 million in an I。 that tests market interest in humanoid robots, a technology that wows but has yet to prove its viability
Six deaths reported among screwworm cases, one directly attributed to the flies
Modern humans carry DNA from two mysterious extinct lineages in addition to Neanderthals and Denisovans。 Their hidden genetic legacy shows that our evolutionary past was shaped by repeated mixing among many different human groups
DNA traces in the Shroud of Turin reveal a remarkable mixture of human lineages, microbes, plants, animals, and coral accumulated through centuries of handling and travel。 The findings do not prove its age or authenticity, but they expose a hidden biological history preserved in the famous cloth
Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA。 The resulting breaks are repeatedly repaired, sometimes with small mistakes that allow new mutations to accumulate。 Researchers believe this self-inflicted damage may help tumors evolve while also creating a
Genetic changes may set off a chain reaction that causes the spine’s natural shock absorbers to harden and deteriorate。 Zebrafish with a faulty collagen-related gene developed mineral buildup and spinal fusion similar to human disc disease。 Researchers were able to reduce the damage using an existing osteoporosis drug and by targeting fat metabolis
Blocking the glycine transporter SLC6A20 restored important brain signaling and improved social, communication, and repetitive behaviors in autism-related mouse models。 The treatment also worked in human brain organoids and showed lasting effects in adult mice, suggesting the brain may remain more treatable later in life than previously thought
Weight loss is not simply a test of willpower。 The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after weight loss。 This biological “memory” helps explain why many people regain weight after dieting and why m
