[:es]Deadly virus turns honey bees into Trojan horses[:]

Social distancing is nothing new to honey bees. When a colony is infected with the deadly Israeli acute paralysis virus (IAPV), bees are less likely to touch or feed their sick nest mates, according to a new study. But the virus appears to have an alarming counterattack: When sick bees try to enter a new…

[:es]The Neanderthal DNA you carry may have surprisingly little impact on your looks, moods[:]

If you think you got your freckles, red hair, or even narcolepsy from a Neanderthal in your family tree, think again. People around the world do carry traces of Neanderthals in their genomes. But a study of tens of thousands of Icelanders finds their Neanderthal legacy had little or no impact on most of their…

[:es]Shrewd water use helped South America’s first empire thrive. So why did a drought destroy it?[:]

When Wari colonists arrived in the Moquegua Valley of southern Peru some 1400 years ago, people already living there were likely nervous. The Wari state, with its capital city of Huari high in the Andes near what is now Ayacucho, Peru, had been expanding its reach. The Wari takeover was violent in places; the invaders…

[:es]Ending coronavirus lockdowns will be a dangerous process of trial and error[:]

After the novel coronavirus made its way from China around the world, one country after another adopted harsh measures to stop SARS-CoV-2 from spreading and overwhelming hospitals. They have hit the pause button on their economies and their citizens’ lives, stopping sports events, religious services, and other social gatherings. School closures in 188 countries affect…

[:es]‘A huge step forward.’ Mutant enzyme could vastly improve recycling of plastic bottles[:]

Recycling isn’t as guilt-free as it seems. Only about 30% of the plastic that goes into soda bottles gets turned into new plastic, and it often ends up as a lower strength version. Now, researchers report they’ve engineered an enzyme that can convert 90% of that same plastic back to its pristine starting materials. Work…

[:es]New genetic tools promise to unlock secrets of microscopic marine life[:]

Fifty percent of the oxygen we breathe comes from ocean microbes. Yet these tiny marine organisms have largely remained a mystery to science. Now, thanks to the efforts of more than 100 researchers around the globe, scientists have found a way to unlock the genomes of a handful of these creatures by genetically engineering their…

[:es]Proteins that sense light also sense taste, at least in fruit flies[:]

Like many animals, you couldn’t see without proteins called opsins, which dwell in the light-sensitive cells of your eyes. A new study reveals for the first time that fruit flies can also use some of these proteins, nestled at the tip of their nose, to taste noxious molecules in their food. Opsins in our bodies…

[:es]Publicado el primer mapa genético de la corteza cerebral[:]

Un nuevo estudio de la revista Science identifica por primera vez variantes genéticas que influyen en las diferencias individuales de la corteza cerebral y cómo se relacionan con el riesgo genético de trastornos como la depresión o el TDHA. Los resultados están disponibles para que la comunidad científica pueda seguir avanzando en el conocimiento de…
