An 81-year-old man from Surrey became the first patient in the U.K. to receive a new “vaccine” designed to treat solid-tumor cancers, such as the skin cancer melanoma. Therapeutic cancer vaccines act as a kind of immunotherapy, meaning they help train the immune system to fight cancer cells. They’re different from vaccines that prevent cancer, … Read more
A puppy has spontaneously regrown his jawbone after part of it was surgically removed because of a cancerous tumor. It is believed to be the first reported case of a dog regenerating its mandible. Veterinarians at Cornell University College of Veterinary Medicine’s Dentistry and Oral Surgery Service first diagnosed Tyson, a 3-month-old French bulldog, with … Read more
A detailed investigation of asteroid Ryugu samples has provided further evidence that the organic molecules which gave rise to life to our planet were brought here by ancient comets. These space rock samples were returned to Earth by Japan’s Hayabusa2 mission, which visited the spinning-top-like space rock Ryugu in 2018. Hayabusa2 spent around 18 months … Read more
NASA’s Perseverance rover has found that Mars’ Jezero crater was at one point filled with water, offering a tantalizing hope that it may have already unearthed fossilized life on the planet. The rover, which first touched down on the crater in February 2021 along with its now-retired helicopter companion Ingenuity, made the discovery using ground-penetrating … Read more
Several children born with a rare, inherited form of deafness can now hear thanks to two new gene therapies, clinical trial results show. Both therapies target the gene for otoferlin, a protein in the inner ear that lets nerve cells translate vibrations from sound into electrical signals that can be interpreted by the brain. Mutations … Read more
To boost the computing power of artificial intelligence (AI), researchers have combined run-of-the-mill machine learning with a sophisticated 3D model of the human brain made of different types of brain tissue grown in the lab. These miniature models of the brain, known as cerebral organoids or “minibrains,” have existed in various forms since 2013. But … Read more
Life has found a home on Earth for around 4 billion years. That’s a significant fraction of the universe’s 13.77 billion-year history. Presumably, if life arose here, it could have appeared anywhere. And for sufficiently broad definitions of life, it might even be possible for life to have appeared mere seconds after the Big Bang. … Read more
Why do common shrews live for only two years, while bowhead whales survive for two centuries? And could the answer give us hints as to how to extend our own, human life spans? The maximum life span of each species is estimated using the age of its longest-living member, and these vary by orders of … Read more
Officially, the colony was called the Mortality-Inhibiting Environment for Mice. Unofficially, it was called mouse heaven. Biologist John Calhoun built the colony at the National Institute of Mental Health in Maryland in 1968. It was a large pen—a 4½-foot cube—with everything a mouse could ever desire: plenty of food and water; a perfect climate; reams … Read more
Using only a sensor-filled helmet combined with artificial intelligence, a team of scientists has announced they can turn a person’s thoughts into written words. In the study, participants read passages of text while wearing a cap that recorded electrical brain activity through their scalp. These electroencephalogram (EEG) recordings were then converted into text using an … Read more
