NASA says a long-running air leak aboard the ISS recently worsened, leading engineers to investigate new suspected crack locations and consider a riskier repair strategy. Astronauts were temporarily moved into a safe haven as a precaution before the repair was postponed for
Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of the planet's environment during that time is limited.
Colors brighten our lives and help define countless items we use daily—from the vibrant clothes we wear to decorative paper and packaging materials. What adds different colors to these things? Dyes, which bind themselves to the structure of the material they are coloring. For
Similar to the way DNA damage can contribute to human diseases such as cancer, it can also disrupt growth, development and survival in plants. Every day, plants endure environmental stresses such as sunlight, radiation, drought and soil stress—all of which can damage their DNA.
Researchers have identified a new Alzheimer’s target and created an experimental compound that blocks a damaging process inside brain cells. In mice, the treatment slowed nerve cell loss, reduced Alzheimer’s-related changes, and even appeared to promote healthier aging.
Over the last decade, podcasts have become big business, with more than a fifth of UK adults listening to podcasts each week. The format particularly resonates with men, who are more likely than women to identify as podcast fans. Men are also overrepresented as podcast hosts.
Almost a quarter of all freshwater species are threatened with extinction. The removal of human-made barriers from rivers, such as dams and weirs, is a popular way to restore water flow and sediment transport to its natural state and allow fish and other aquatic wildlife to
Thanks to effective therapies, more and more people are now able to live with or after cancer in the long term. Consequently, the number of patients affected by the long-term effects of their treatment is also increasing. Secondary leukemias are particularly serious. These can
