CAPE CANAVERAL, Fla. — A new SpaceX rocket launched a pristine batch of Starlink internet satellites into orbit late Wednesday (Feb. 26) in a dazzling nighttime liftoff. A Falcon 9 rocket carrying 21 Starlink satellites soared into the night time sky from a SpaceX’s Launch Complex-40, at the Cape Canaveral Space Force Station, in Florida….
Imagine floating in space, gazing on a frozen white orb. The ball hangs in the void, lonely and gleaming in the light from its star. From pole to equator, the sphere is covered in a thick crust of ice. In orbit around the white planet is a single cratered moon. You are gazing on Earth…
Heat takes it out of you. After a long, hot day, we feel tired and grumpy. But sustained periods of heat do more than that – they age us faster. Cumulative heat stress changes our epigenetics – how our cells turn on or off gene switches in response to environmental pressure. Now, new research from…
For certain fishes, evolution is easy. After tracking the evolution of teeth in cichlid fishes from Africa, a team of researchers has found that these fishes have developed the ability to evolve rapidly, allowing them to adapt their teeth readily for different habitats and diets. This ability, the researchers report today in a study in…
Doctors in the US have treated a fetus with a rapidly progressive congenital disease from inside the womb for the very first time. Instead of giving medicine to a child with severe neuromuscular complications after they are born, a new case study details how a prospective mother agreed to take the medicine for her developing…
Few things in life are as fraught as how we communicate, whether it is anxiously picking the right words to scribble in a Valentine’s Day card or agonising over how to ask your boss an awkward question. And that is before you even get into the murkier realm of digital communication and the newfound perils…
Everyone knows that maintaining a clean kitchen is essential for safe food preparation. Failing to properly sanitize utensils after use can lead to foodborne illnesses from bacterial growth. Alongside dish sponges, cutting boards — particularly those used for raw meat — are hotspots for bacteria. Instead of relying solely on human-devised cleaning methods to combat…
CAPE CANAVERAL, Fla. — The private Athena lunar lander is on its way to the moon. A SpaceX Falcon 9 rocket lifted off shortly after sunset this evening (Feb. 26), carrying Athena and NASA’s ride-along Lunar Trailblazer orbiter aloft against a darkening sky here at NASA’s Kennedy Space Center (KSC). Athena — which was built…
Selenium is a nutrient that plays a crucial role in human health, contributing to the thyroid and immune function, DNA repair, and cardiovascular and cognitive health. It acts as an antioxidant – substances that protect cells from unstable molecules that can damage DNA, proteins and cell membranes. It can even protect against cancer. Selenium is…
The AMOC brings warm water north from the tropics near the surface and takes cool water in the opposite direction in the deep ocean NOAA A critical ocean current is unlikely to shut down before the end of this century even under the most extreme climate scenarios, according to new findings that undermine doomsday predictions…
