Extreme Climate Survey Scientific news is collecting questions from readers about how to navigate our planet’s changing climate. What do you want to know about extreme heat and how it can lead to extreme weather events? Most black holes that astronomers have discovered fall into one of two categories. They are either stellar-mass black holes, up to 100 times the mass of the Sun, or supermassive black holes, which reside in the centers of galaxies and are hundreds of thousands to billions of times the mass of the Sun. the sun . Black holes with masses in between may help…

What do you want to know about extreme heat and how it can lead to extreme weather events? “These changes have been coming for a long time,” says Krebs. “It’s important, from a public health standpoint, that these changes are being made, especially because it’s such a huge human risk to have a dog come into a country that potentially has rabies that we don’t know about.” Rabies is a zoonotic infectious disease, transmitted from animals to humans. In the United States,…
An ancient Egyptian mummy, dubbed the “Screaming Woman” for what appears to be an open-mouthed look of pain or fear, may have had that expression fixed in place by a rare muscle reaction when she died. The sudden muscle stiffness associated with violent deaths under extreme physical and emotional stress, known as cadaveric spasm, may explain this silent scream of the roughly 3,500-year-old mummy, researchers report Aug. 2 in Frontiers in Medicine. The cause of death of the Screaming Woman remains undetermined, so a cadaveric spasm cannot be confirmed as the reason for her alarming appearance. But new evidence of…

What do you want to know about extreme heat and how it can lead to extreme weather events? “These two papers reinforce each other tremendously, and I think their story is becoming really compelling,” says Alessandro Morbidelli, a planetary scientist at the Côte d’Azur Observatory in Nice, France, who was not part of either research team. The four planets closest to the sun—Mercury, Venus, Earth, and Mars—all formed in the interior of the solar nebula, the disk of gas and dust that…

What do you want to know about extreme heat and how it can lead to extreme weather events? The Great Red Spot is the largest vortex in our solar system (SN: 12/12/17). Located in Jupiter’s southern hemisphere, wind gusts exceed 600 kilometers per hour. But it’s not clear how far back in time this place goes and what made it spin. Fortunately, some past planet observers sketched what they saw through their telescopes. “It was very exciting to see in old articles…
The rotation of the Earth has been measured many times – but never like this. At first, scientists used entangled quantum particles called photons to detect the speed at which the globe spins. The achievement is a step toward investigating one of physics’ greatest mysteries: how the tiny world of quantum physics interacts with gravity. This interferometer is mounted on a square frame that can be rotated to allow scientists to detect the rotation of the Earth or, by comparison, be insensitive to it. The photons travel through a 2-kilometer-long optical fiber, which rotates many times around the 1.4-meter-long frame.Raffaele…

What do you want to know about extreme heat and how it can lead to extreme weather events? “The possibility of a large-scale earthquake is considered to be relatively higher than under normal conditions,” the JMA said in an advisory accompanying Thursday’s alert. The mega-earthquake alert is expected to remain in effect for about a week, though the agency advises residents across southern Japan to remain cautious and prepared even after the period has passed. How high is the risk of a…

What do you want to know about extreme heat and how it can lead to extreme weather events? The idea is intriguing, say researchers familiar with the study. But they are not convinced that the pyramid builders ever used such a device. Landreau, who has a background in materials science and plasma physics, founded Paleotechnic for the study of ancient technologies. There is no generally accepted explanation for how the ancient Egyptians built the pyramids from millions of massive blocks. Those stones…

What do you want to know about extreme heat and how it can lead to extreme weather events? This isn’t the first sign of organics on Mars – the Curiosity rover detected organic molecules in a region called Gale Crater in 2014 (SN: 16/12/14). But scientists have struggled to identify organics since Perseverance landed in an ancient dried-up lake called Jezero Crater in 2021, says Stack Morgan (SN: 17.2.21). Adding to the excitement, the reddish rock is speckled with tiny white dots…

What do you want to know about extreme heat and how it can lead to extreme weather events? “We can use thermal facial imaging to diagnose these diseases with a pretty good accuracy of about 80 percent,” says computational biologist Jing-Dong Jackie Han of Peking University in Beijing. “The thermal pattern of the face really tells you more about health status.” Han and her colleagues also found that the temperature of the nose decreases with age at a faster rate than other…
