Most cancer mutations are due to random DNA copying ‘mistakes’

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that cause cancer. Their research is grounded on a novel mathematical model based on DNA sequencing and epidemiologic data from around the world. "It is well-known that we…

UNSW scientists unveil a giant leap for anti-aging

UNSW researchers have identified a critical step in the molecular process that allows cells to repair damaged DNA – and it could mean big things for the future of anti-ageing drugs, childhood cancer survivors and even astronauts. UNSW researchers have made a discovery that could lead to a revolutionary drug that actually reverses ageing, improves DNA…

Key to Tardigrades’ ‘Superpowers’ Identified in Their DNA

Microscopic, blobby-bodied tardigrades — also known as "water bears" — are famed for their ability to survive in extreme conditions, even appearing to come back from the dead. But although tardigrades' hardiness has intrigued scientists for over 250 years, the mechanisms that enable these animals to recover after drying out for a decade or longer…

Gene found to cause sudden death in young people

Researchers from Canada, South Africa and Italy have identified a new gene that can lead to sudden death among young people and athletes. The gene, called CDH2, causes arrhythmogenic right ventricle cardiomyopathy (ARVC), which is a genetic disorder that predisposes patients to cardiac arrest and is a major cause of unexpected death in seemingly healthy…

Colorectal Cancer Rates Rise Sharply in Younger US Adults

Colorectal cancer rates are on the rise among millennials and Gen Xers in the U.S., a new study finds. The findings come as rates of these cancers have continued to decline in adults ages 55 and up, according to the study. People in the U.S. born in 1990 now have double the risk of colon…

Researchers Have Found a Way to Delay Aging

FOCUSING ON THE CELL’S POWER HOUSE More and more, scientists are becoming convinced that aging is a disease that can be stopped or, at least, slowed. Recently, researchers from Russia and Sweden investigated this idea further in a joint study by Lomonosov Moscow State University and Stockholm University. Their study, published in the journal Aging, focuses on the…

Woolly mammoth on verge of resurrection, scientists reveal

The woolly mammoth vanished from the Earth 4,000 years ago, but now scientists say they are on the brink of resurrecting the ancient beast in a revised form, through an ambitious feat of genetic engineering. Speaking ahead of the American Association for the Advancement of Science (AAAS) annual meeting in Boston this week, the scientist…

Genetic study identifies fourteen new developmental disorders in children

The largest ever genetic study of children with previously undiagnosed rare developmental disorders has discovered 14 new developmental disorders. Published today in Nature, the research led by scientists at the Wellcome Trust Sanger Institute also provided diagnoses of rare conditions for over a thousand children and their families. These diagnoses allow families with the same…

TSRI Scientists Discover Master Regulator of Cellular Aging

Scientists at The Scripps Research Institute (TSRI) have discovered a protein that fine-tunes the cellular clock involved in aging. This novel protein, named TZAP, binds the ends of chromosomes and determines how long telomeres, the segments of DNA that protect chromosome ends, can be. Understanding telomere length is crucial because telomeres set the lifespan of…

Promising new drug stops spread of melanoma by 90 percent

Michigan State University researchers have discovered that a chemical compound, and potential new drug, reduces the spread of melanoma cells by up to 90 percent. The human-made, small-molecule drug compound goes after a gene's ability to produce RNA molecules and certain proteins in melanoma tumors. This gene activity, or transcription process, causes the disease to…
