Oregon wildfire forms 'fire clouds' that pose danger below

Smoke and heat from a massive wildfire in southeastern Oregon are creating giant "fire clouds" over the blaze—dangerous columns of smoke and ash that can reach up to 6 miles (10 kilometers) in the sky and are visible from more than 100 miles (160 kilometers) away.

Scientists create tool to explore billions of social media messages, potentially predict political and financial turmoil

Scientists have invented an instrument to peer deeply into billions of Twitter posts -- providing an unprecedented, minute-by-minute view of popularity, from rising political movements, to K-pop, to emerging diseases. The tool -- called the Storywrangler -- gathers phrases across 150 different languages, analyzing the rise and fall of ideas and stories, each day, among people around the world. The...

Climate change to bring more intense storms across Europe

Investigating how climate affects intense rainstorms across Europe, climate experts have shown there will be a significant future increase in the occurrence of slow-moving intense rainstorms. The scientists estimate that these slow-moving storms may be 14 times more frequent across land by the end of the century. It is these slow-moving storms that have the potential for very high precipitation...

Air-powered computer memory helps soft robot control movements

Engineers made a pneumatic RAM chip using microfluidic valves instead of electronic transistors. The valves remain sealed against a pressure differential even when disconnected from an air supply line, creating trapped pressure differentials that function as memories and maintain the states of a robot's actuators. Dense arrays of these valves can perform advanced operations and reduce the...

Global Electricity Production Is Roaring Back—and So Are CO2 Emissions

Carbon emissions from power plants around the world declined in recent years, but they’re poised to make a dramatic comeback over the next 18 months, according to a worrying report released July 15 by the International Energy Agency (IEA). https://datawrapper.dwcdn.net/cQ7Ua/2/ COVID-19 lockdowns were responsible for some of the recent decline, as office buildings, for instance, reduced...

He was flanked by Chris Whitty, the chief medical officer, and Sir Patrick Vallance, the government’s chief scientific adviser. Both men were there to show that Mr Johnson is...

Role of deep-sea microbial predators at hydrothermal vents examined

The hydrothermal vent fluids from the Gorda Ridge spreading center in the northeast Pacific Ocean create a biological hub of activity in the deep sea. There, in the dark ocean, a unique food web thrives not on photosynthesis but rather on chemical energy from the venting fluids. Among the creatures having a field day feasting at the Gorda Ridge vents is a diverse assortment of microbial...
