Analysis: the vaccine strategy and staggered easing of restrictions have worked well. The next step is crucialCoronavirus – latest updatesSee all our coronavirus coverageThe handling of the coronavirus crisis in the UK has provided few moments to celebrate, but the day we reach zero deaths from the disease will clearly be one to toast. That day may not be far off. On Tuesday, the UK reported...
America's new normal temperature is a degree hotter than it was just two decades ago.
Relatives of the giant crocodile might have been kings of the waterways during the Cretaceous period, eating anything—including dinosaurs—that got a little too close to the water's edge, but the largest of these apex predators still started off small. Figuring out how these little crocs grew up in a world surrounded by giants is no small task. Now crocs fossils from Texas are shedding light on...
When a drinking glass falls on the floor and breaks, the shards will vary in size from large to extremely small. For the broken glass of a bus shelter, the story is different: all fragments have roughly the same size. Researchers from the University of Amsterdam, Unilever Vlaardingen and EPFL Lausanne investigated the breaking phenomenon, and discovered that two very different processes cause the...
Wherever scientists look, they can spot them: whether in remote mountain lakes, in Arctic sea ice, in the deep-ocean floor or in air samples, even in edible fish—thousands upon thousands of microscopic plastic particles in the micro to millimeter range. This microplastic is now even considered one of the defining features of the Anthropocene, the age of the Earth shaped by modern humans.
A new auroral phenomenon discovered by Finnish researchers a year ago is probably caused by areas of increased oxygen atom density occurring in an atmospheric wave channel. The speculative explanation offered by the researchers gained support from a new study.
This overlay shows radio (orange) and infrared images of a giant molecular cloud called W49A, where new stars are being formed. A team of astronomers led by Chris DePree of Agnes Scott College used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) to make new, high-resolution radio images of this cluster of still-forming, massive stars. W49A, 36,000 light-years from Earth,...
Pyrosomes, named after the Greek words for 'fire bodies' due their bright bioluminescence, are pelagic tunicates that spend their entire lives swimming in the open ocean. They are made up of many smaller animals, known as zooids, that sit together in a tubular matrix, known as tunic (hence the name pelagic tunicates). Because they live in the open ocean, they generally go unnoticed. In spite of...
Measures to contain the Corona pandemic are the subject of politically charged debate and tend to polarize segments of the population. Those who support the measures motivate their acquaintances to follow the rules, while those who oppose them call for resistance in social media. But how exactly do politicization and social mobilization affect the incidence of infection? Researchers at the Max...
