Gliomas are a major cause of cancer-related deaths in younger adults. About 7,000 patients harbor a common genetic mutation that affects the enzyme isocitrate dehydrogenase 1. This mutated enzyme, called mIDH1, can produce ...
Two new studies from Johns Hopkins University are providing scientists with an unprecedented view of how human cells repair one of the most dangerous forms of genetic damage: a break that severs both strands of the DNA double ...
At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart muscle cells divide ...
For more than 170 years, paleontologists have been trying to solve the mystery of what created the strangely uniform hexagonal tunnels found in fossils. In a new study published in Earth Science Reviews, a team of researchers ...
As we age, some of the cells in our body enter a state of senescence, in which they stop dividing but do not die. Those senescent cells can contribute to age-related disorders such as cancer, tissue degeneration and inflammatory ...
Across Appalachia and the Rust Belt region, including throughout the city of Pittsburgh, former industrial sites are being transformed into new neighborhoods, research centers and technology hubs.
The malaria parasite is able to detect changes in its host's environment and respond by increasing the production of sexual forms capable of being transmitted to mosquitoes. A study led by the Barcelona Institute for Global ...
A previously unknown cat species has been identified in plain sight: at a wildlife sanctuary in Bolivia, where the small, spotted feline had been living for years.
Research scientist Ashish Rajurkar kneels in the dirt, lifting a large clod of soil tangled around a soybean plant. He knocks away pieces of earth from the plant's roots, which slope straight down instead of out to the side ...
CRISPR may be a powerful technology for gene editing, but the system existed in bacteria long before scientists began using it. For billions of years, CRISPR has acted as a natural immune system in bacteria and other microbes, ...
