If you’re looking for starry skies, exotic plant life and extreme weather on your summer vacation, NASA’s Exoplanet Travel Bureau has just the spot. Consider a trip to Kepler 186f. This extrasolar planet is nearly 558 light-years away, so a real trip may be out of your budget — and astronomers aren’t sure if the […]
On a warm summer evening, a visitor to 1920s Göttingen, Germany, might have heard the hubbub of a party from an apartment on Friedländer Way. A glimpse through the window would reveal a gathering of scholars. The wine would be flowing and the air buzzing with conversations centered on mathematical problems of the day. The […]
A heavy element’s nucleus is all bent out of shape. Nobelium — element number 102 on the periodic table — has an atomic nucleus that is deformed into the shape of an American football, scientists report in the June 8 Physical Review Letters. The element is the heaviest yet to have its nucleus sized up. […]
New tech is revealing how young stars have an outsized influence on their environment. In this image from the Very Large Telescope in Chile, hundreds of newborn stars sculpt and illuminate gas and dust in their stellar nursery. Released July 11 by the European Southern Observatory, the image shows star cluster RCW 38, which is […]
When invasive rats chow down on island seabirds, coral reefs suffer. Researchers studied islands with and without the rodents in the Chagos Archipelago in the Indian Ocean. On rat-free isles, there were on average 1,243 birds per hectare compared with about two birds per hectare on rat-infested islands, the team found. And these rodentless islands […]
Painkillers crafted with a part of the wrinkle-smoothing drug Botox provide long-term pain relief in mice. Researchers added the modified Botox to molecules that target pain-messaging nerve cells. Mice given a single spinal injection of the new drugs showed signs of pain relief for the full duration of the experiments, around three weeks, researchers report […]
An intergalactic race between light and a bizarre subatomic particle called a neutrino has ended in a draw. The tie suggests that high-energy neutrinos, which are so lightweight they behave as if they’re massless, adhere to a basic rule of physics: Massless particles travel at the speed of light. Comparing the arrival times of a […]
In the final frenzy of reproduction and death, social amoebas secrete proteins that help preserve a starter kit of food for its offspring. Dictyostelium discoideum, a type of slime mold in soil, eats bacteria. Some wild forms of this species essentially farm the microbes, passing them along in spore cases that give the next generation […]
A new species of Ebola virus has been discovered in bats in Sierra Leone, the country’s government announced July 26. Researchers looking to identify new viruses before the pathogens spill over into human populations found the new Ebola strain while sampling bats in the northern Bombali district. This is the sixth known species of the […]
For nearly 60 years, scientists in Siberia have bred silver foxes in an attempt to replay how domestication occurred thousands of years ago. Now, in a first, researchers have compiled the genetic instruction book, or genome, of Vulpes vulpes, the red fox species that includes the silver-coated variant. This long-awaited study of the foxes’ DNA […]
