1980 results for "dna repair"
A new study shows melatonin supplements help night shift workers repair DNA damage by 80% during sleep. The discovery could offer a simple way to protect millions who work overnight from long-term health risks.
Scientists discovered why people with the APOE2 gene live longer and rarely get Alzheimer's: their brain cells are better at repairing DNA damage. The breakthrough could lead to new treatments that protect everyone's brain, especially those at higher risk.
Scientists discovered that a common DNA repair gene, when overproduced, makes tumors vulnerable to treatments previously reserved for rare inherited cancers. The finding could help 20-30% of breast and ovarian cancer patients access more effective therapies.
A small clinical trial found that melatonin supplements boosted DNA repair in night shift workers by 80% during daytime sleep. The discovery points to a simple way to counter hidden health risks linked to overnight work.
Scientists built an AI that designs synthetic DNA switches capable of turning genes on and off in specific cells, potentially transforming how we treat diseases like leukemia. In lab tests, these AI-generated sequences actually outperformed natural DNA at reactivating a protective gene in leukemia cells.
A Chinese repair technician rescued a destroyed graphics card worth over $1,000 by transplanting its chip onto a new circuit board. The card was physically smashed but now works perfectly again.
Apple just released its most repair-friendly laptop since 2014, making it easier for students and schools to fix broken devices themselves. The $499 MacBook Neo uses screws instead of glue, though repair experts say there's still room for improvement.
Scientists discovered a bacterial protein that creates DNA without copying existing genetic material—something biology textbooks say shouldn't be possible. The breakthrough could lead to revolutionary new tools for building custom DNA molecules.
Colorado lawmakers just voted down a tech industry-backed bill that would have gutted the state's landmark right-to-repair protections. After a marathon hearing filled with testimony from repair advocates, small businesses, and everyday citizens, the House committee killed the proposal 7-4.
A breakthrough AI tool from Google DeepMind can read massive DNA sequences with single-letter precision, helping scientists predict how genetic changes lead to diseases like cancer. The free research tool is already helping researchers understand the 98% of human DNA once dismissed as "junk."
After years of farmers fighting for the right to fix their own equipment, John Deere will pay $99 million and make repair tools widely available for the next decade. It's a major win for 200,000 farmers who can now repair tractors themselves instead of waiting weeks for approved dealerships.
Scientists discovered all five building blocks of DNA on asteroid Ryugu, suggesting the ingredients for life might be common throughout our solar system. The findings support the possibility that life's essential components could have arrived on Earth from space.
Frozen droppings from prehistoric squirrels in Canada's Yukon have revealed DNA from woolly mammoths, ancient big cats, and dozens of other ice age creatures. The 700,000-year-old genetic material ranks among the oldest DNA ever recovered, offering scientists an extraordinary window into ancient life.
Scientists discovered that cells can fix themselves while dividing, replacing weak links with stronger ones to prevent cancer and birth defects. This breakthrough reveals how our bodies perfectly split DNA millions of times every second.

Scientists at UC San Francisco discovered that cells can repair themselves while dividing, replacing weak protein links with stronger ones to prevent cancer-causing errors. This breakthrough reveals how our bodies safely complete millions of cell divisions every second.
Scientists in Hungary discovered how cells coordinate gene activity and DNA repair, opening doors to more effective cancer therapies. The breakthrough could help make tumor cells more vulnerable to existing treatments.
Researchers discovered a way to make treatment-resistant cancer cells vulnerable again by breaking down their DNA repair machinery. The breakthrough could help millions of patients whose cancers stopped responding to existing therapies.
Victoria Foe discovered that the DNA scientists dismissed as "junk" may actually be a crucial timing device that makes complex life possible. Her decades-long quest, fueled by personal loss and scientific curiosity, is rewriting what we know about evolution.
A protein known for causing ALS and dementia also controls DNA repair, opening new doors for treating both brain diseases and cancer. The discovery could reshape how doctors approach two of medicine's biggest challenges.
Researchers are creating microscopic robots made from DNA that could one day deliver drugs directly to diseased cells and capture viruses in the bloodstream. While still experimental, these molecular machines represent a breakthrough in combining biology with robotics.
