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? The study doesn’t completely rule out an intermediate-mass black hole, but if one is there, it’s much smaller than previously suggested. No black holes larger than 6,000 times the mass of the Sun exist in the star cluster, his team concludes in work submitted Aug. 1 to arXiv.org. In contrast, the other research team said that seven stars near the center of this cluster…

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? Over six episodes, viewers tag along on expeditions to study marine life in the shallow tropical waters of the Caribbean, the seemingly endless depths of the Atlantic Ocean and along the frigid shores of the Arctic Ocean. Unsurprisingly for a series produced and broadcast by Cameron, OceanXplorers takes every stereotype of the laid-back, relaxing nature documentary, secures it in a camera trap, and throws…
Even the microwave oven in your kitchen is not immune to bacteria. The radiant environment inside a microwave oven can seem inhospitable to germs. But swabs from microwave ovens in several different areas identified more than 100 bacterial species, researchers report Aug. 7 in Frontiers in Microbiology. This is the first time scientists have documented the microbial communities living in microwave ovens, according to the researchers. Microbiologist Manuel Porcar and colleagues wiped the insides—including the walls and turntable—of 30 microwave ovens that were being actively used in three different environments: 10 from kitchens, 10 from laboratories, and 10 from other…

What do you want to know about extreme heat and how it can lead to extreme weather events? The original “Wow!” the signal was detected decades ago by the Big Ear radio telescope at Ohio State University. As the telescope scanned the sky, a computer program converted the incoming radio signals into a series of letters and numbers representing their intensity and printed them overnight. In the morning, astronomer Jerry Ehman and his colleagues would look at the prints for anything interesting.…

What do you want to know about extreme heat and how it can lead to extreme weather events? Most “radiant cooling” designs involve roofs designed to receive and then emit the sun’s energy in infrared wavelengths that radiate through the Earth’s atmosphere and into space. Such roofs can be decorated with plants, painted white to better reflect the sun’s rays, or coated with materials that are both highly reflective and highly emissive (SN: 2/6/23). Vertical walls are more difficult to cool, says…
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? The extreme heat and rain are scary enough on their own, and it’s getting hotter with climate change. But combined, these conditions can bring another enemy: mosquitoes. Mosquitoes thrive when there is plenty of water around to lay eggs, and warm temperatures help those offspring thrive. The bugs themselves are not a problem – although their bites are annoyingly itchy. But the viruses, bacteria…
A distant stellar nursery holds a cluster of newborn worlds the size of Jupiter, the smallest of which is surrounded by a disk of dust that may one day form moons. The detailed discovery, made thanks to the unprecedented sensitivity of the James Webb Space Telescope, could provide new insights into the formation of stars and planets, researchers report in a study in press at Astronomical Journal. Stars are born from large clouds of gas and dust when pockets of material collapse under the influence of gravity. The same process can also create smaller non-stellar objects, such as giant planets…

What do you want to know about extreme heat and how it can lead to extreme weather events? At the center of this story are cratons, large blocks of mostly crystalline rock that typically occupy the interior of continents. They are the oldest fragments of the Earth’s crust, with many of them having formed more than 2.5 billion years ago, during the Archean Eon. Much of the crust that once existed on Earth has been destroyed at subduction zones, where one tectonic…
