Emissions from both new and existing natural-gas plants would be regulated under the new rules. Photo: David Paul Morris/Bloomberg NewsThe Environmental Protection Agency is preparing to issue new rules that would slash the amount of planet-warming greenhouse gases produced by U.S. power plants in the coming decades, according to people familiar with the matter. For the first time, emissions from both new and existing natural-gas plants, as well as existing coal-fired plants, would be regulated, the people said. Electric utilities would have various options for meeting the tougher standards by installing new carbon-capture systems or switching to cleaner fuels such as hydrogen, according to the people.

The retreating snowpack threatens supplies of freshwater to cities and farms throughout the Alps watershed, but it is also lengthening the region’s summer tourism season.

Patients at Johns Hopkins Hospital who are suspected of having a stroke might get an unusual request from physicians: Can we film your face? The doctors’ goal is to identify stroke patients by facial characteristics instead of waiting for brain scans or blood tests, helping speed both treatment and recovery. The Johns Hopkins team is training a computer algorithm to recognize changes in the patients’ features, such as the paralysis of certain facial muscles or unusual eye movements, that might indicate damage to the brain from a stroke as opposed to seizures, severe migraines or anxiety disorders.

Artificial Intelligence 101: Why It’s Different This TimeThere is so much being said about artificial intelligence these days. In order to understand this latest wave of AI, it is important to know how it works and why this moment is different from developments in the past.

More Water Found on Moon, Locked in Tiny Glass Beads
  + stars: | 2023-03-27 | by ( Eric Niiler | ) www.wsj.com   time to read: 1 min
The moon’s surface contains a new source of water found embedded in microscopic glass beads, which might one day help future astronauts produce drinking water, breathable air and even rocket fuel, scientists say. The findings come from a Chinese rover that spent two weeks on the moon in 2020. The Chang’e 5 rover drilled several feet into the lunar surface and returned 3.7 pounds of material, among which were the glass beads from an impact crater, according to a paper published Monday in the journal Nature Geoscience.
A United Nations panel of scientists said there is a “feasible, but narrow pathway” to avoid the worst effects of climate change, however to do so, the world’s nations must together cut greenhouse-gas emissions 60% by 2035 to limit warming to 1.5 degrees Celsius over preindustrial levels. That level of cuts would require a massive and rapid shift in the world’s energy supply that is under way in some countries, but has been stifled by the war in Ukraine, the global energy crisis and thirst for economic growth in countries like China and India. Global greenhouse-gas emissions reached record levels in 2022 and are projected to continue their upward trajectory, according to scientists.

The ideal temperature for this device is 26 degrees Fahrenheit, but the thermometer is already climbing toward 30 degrees. “It has been marginal,” Mr. McCluskey said about the winter season. “We really have to hammer on the guns whenever we have the temps and get them on when we can.”
Meta AI researchers produced this digital representation of one million proteins using a new artificial-intelligence tool known as ESMFold. Facebook parent company Meta Platforms Inc. has created a tool to predict the structure of hundreds of millions of proteins using artificial intelligence. Researchers say it promises to deepen scientists’ understanding of biology, and perhaps speed the discovery of new drugs. Meta’s research arm, Meta AI, used the new AI-based computer program known as ESMFold to create a public database of 617 million predicted proteins. Proteins are the building blocks of life and of many medicines, required for the function of tissues, organs and cells.
NEWRY, Maine— An hour before dawn, Ian McCluskey adjusts his goggles and plunges the sleeve of his jacket into a spray of ice crystals arcing out of a nearby fan-shaped snow-making machine. Mr. McCluskey is testing the quality of machine-made snow—as the spray settles on his sleeve “you can tell whether you are getting wetter snowball snow, or something that is very dry and good for resurfacing a trail,” shouts Mr. McCluskey, a 28-year-old snow-making supervisor at Sunday River Resort in western Maine. On this night, the machine-made snow is clumpy and won’t spread evenly. The air is too warm and humid to run this brand-new automated snow-making machine, or snow gun, for more than a few minutes.
Mercury, arsenic and other toxic metals are released into the air from power-plant smokestacks and make their way into U.S. waterways and to the food chain. The Biden administration has reinstated an Obama-era rule on mercury and other toxic chemicals that are emitted from coal-fired and oil-fired power plants, pollutants that the Environmental Protection Agency says are a health risk to people who live near these facilities. EPA officials said Friday that the rule, known as the 2012 Mercury and Air Toxics Standards, is “appropriate and necessary” to regulate emissions from power plants under the existing 1990 Clean Air Act.

AI Is Already Transforming HealthcareThe healthcare sector is already being transformed by the use of artificial intelligence. But what are the drawbacks to its use and what developments in the use of AI will come to healthcare next? The authors of the new book “Can We Trust AI?” WSJ reporter Eric Niiler and researcher Rama Chellappa addressed these questions in a Live Q&A. Zoe Thomas hosts.
