Biology news about cells, genes, evolution, and living systems. Discover new research on how life works, from molecular mechanisms to ecosystems.
The Alzheimer’s risk gene APOE4 may actively damage brain blood vessels and sabotage the cellular systems that remove harmful proteins. Researchers were able to reverse some of these effects in experiments, revealing ...
Read article →Genetic evidence has revealed a previously unknown gentoo penguin species on the remote Kerguelen Islands and shown that gentoos actually consist of four distinct species. The discovery also highlights a growing threa...
Read article →Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrie...
Read article →A single-celled organism can shrink to one-quarter of its length in milliseconds using a remarkable calcium-powered protein “fishnet.” Scientists hope its unusual machinery could inspire artificial muscles capable of ...
Read article →Scientists discovered that aging cells can use malfunctioning mitochondria to unlock inflammatory genes and keep the immune system stuck in a prolonged state of alert. Blocking one part of this process reduced inflamm...
Read article →UCLA researchers developed ready-made cancer-fighting T cells from cord blood stem cells that can attack solid tumors through two separate detection systems. In mice, a single dose controlled cancer and extended survi...
Read article →Insects quietly hold much of the natural world together, yet conservation efforts are overlooking the tropical regions where more than 80 percent of insect species live. Monash University researchers have developed a ...
Read article →Wild monkeys in West Africa can climb vertical tree trunks using foot flexibility scientists did not realize they possessed. The discovery challenges a key assumption about what the last common ancestor of humans and ...
Read article →Scientists have discovered seven new species of Madagascar’s elusive diamond frogs, using DNA from modern and century-old museum specimens to solve a long-running biological puzzle. The findings reveal surprising hidd...
Read article →DNA from a nearly 190-year-old museum specimen has helped scientists confirm a distinct Himalayan pangolin species hiding in plain sight in Nepal and northern India. The discovery could give conservationists a powerfu...
Read article →A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible “evolutionary highways.” These one-way genetic changes preserve c...
