☆ Intriguing moon water source found in glass beads from impacts
▼ + stars: | 2023-03-27 | by ( Will Dunham | ) www.reuters.com time to read: +4 min

The researchers see promise in obtaining water from the glass beads, perhaps through a heating process to release vapor that would then turn into liquid through condensation. "We can simply heat these glass beads to free the water stored in them," said planetary scientist and study co-author Hejiu Hui of Nanjing University in China. The glass beads were found to hold a water content of up to about 2,000 parts per million by weight. Hu said he believes that such impact glass beads are a common part of lunar soils, found globally and spread evenly. The interaction of the solar wind with lunar surface materials could sustain a water cycle on the moon, with the glass beads absorbing the water and acting as a repository for it, the researchers said.

☆ The mysterious iron ball at the center of the Earth may have stopped spinning and reversed direction

The Earth's inner core may have recently stopped rotating and reversed direction, a new study found. Published in "Nature Geoscience" this week, the peer-reviewed research suggests that the solid inner core of the Earth could experience changes in its rotation every several decades. The inner core, which is mostly composed of pure, solid iron, is long thought to have rotated, differing from the liquid outer core and the other layers of the Earth. The study may help shed further light on the mysterious nature of the inner core and how it interacts with Earth's other layers. Please check back for updates.

☆ Earth’s Inner Core May Be Reversing Its Rotation, Study Finds

A team of researchers from China believe the Earth’s inner core has reversed its rotation after they analyzed earthquake-driven seismic waves as they pass through the Earth. In a study published Monday in the journal Nature Geoscience, researchers said the reversal of the inner core rotation would shorten the length of the day by a fraction of a millisecond over the course of a year, and might have a small effect on Earth’s magnetic field, but wouldn’t affect life on the surface. The Earth’s inner core is made of iron and nickel and is separated from the rest of the solid Earth by the liquid outer core, enabling it to rotate differently than the rest of the planet.

☆ Tackling the threat of mudslides in soaked California

Matt Udkow / Santa Barbara County Fire Department via AP fileWhy is California prone to mudslides? Since New Year’s Eve, the California Department of Conservation’s landslide mapping team has documented more than 300 landslides. Lancaster said California has dramatically increased its efforts to identify hotspots since the Montecito mudslides. After the 2018 mudslides hit Montecito, the Los Angeles Times reported that debris basins above the community were undersized and hadn’t been sufficiently emptied. The organization hired an engineering company to map the canyons and installed debris nets.

☆ I moved to the US to pursue a career in academia before realizing it's a broken system. Here's how I pivoted to climate tech and found a job that made me happier than ever.

☆ I'm a scientist and a model. My days include tagging alligators, hunting pythons, and posing at luxury events in heels and full makeup.

When people who know her as a model discover she's a scientist, they respect her more, she said. We always had four wheelers and creeks and stuff like that, so I think that's definitely why I'm outdoorsy. I also do other things on the side, including python hunting, shark diving, and tagging of various species like alligators. Now I have contracts with some clothing and drink companies, and I'm also signed with an agency that does luxury event modeling. As a model, when you're talking to somebody and they find out you're a scientist it's almost like the respect for you changes.

☆ Where did Earth’s water come from? This meteorite might hold the answer

London CNN —If you’ve ever wondered where water on Earth comes from, new research on a meteorite which landed in a family’s front yard in England last year may have just the answer. Researchers from London’s Natural History Museum and the University of Glasgow, in Scotland, studied a meteorite found in the town of Winchcombe, Gloucestershire, to discover it contained water similar to that found on Earth. Approximately 71% of the Earth’s surface is covered in water, with oceans holding about 96.5% of all water, according to the US Geological Survey. The team, which measured the ratio of hydrogen isotopes in the water, found that it closely resembled the composition of water on Earth, according to a press release from the Natural History Museum. Samples of the Winchcombe meteorite are currently on public display at the Natural History Museum in London, the Winchcombe Museum, and The Wilson (Art Gallery) in Gloucestshire.

☆ Studiu: Marea mai caldă din Arctica, responsabilă de valurile de frig din Europa

Marea Arctică, de pe care gheaţa dispare sub efectul încălzirii climei, contribuie în mod direct la ninsorile abundente din Europa, cum ar fi episodul glacial din 2018 supranumit ''Bestia din Est'', conform unui studiu publicat joi, transmite agerpres.ro. Acest eveniment, care a paralizat o mare parte din nordul Europei în februarie şi martie 2018, a provocat daune de peste un miliard de euro pe zi doar în Regatul Unit. Astfel, aproximativ 140 de gigatone de apă s-au evaporat din mare, reprezentând 88% din umiditatea care a căzut sub formă de zăpadă peste Europa, conform calculelor oamenilor de ştiinţă. "Va însemna întreruperi în aprovizionarea cu alimente şi combustibil, distrugerea culturilor...", a atras atenţia Jeffrey Welker de la Universitatea din Alaska din oraşul american Anchorage. "Poate părea contraintuitiv" faptul că oceanul din regiunea Polului Nord care se încălzeşte provoacă mai multă zăpadă în Europa, "însă natura este complexă, iar ceea ce se întâmplă în Arctica nu rămâne în Arctica", a precizat Hannah Bailey.

☆ Открытие сейсмологов: Бывший кусок дна Тихого океана расположен под Китаем

Сейсмологи из Университета Райса (США) обнаружили нижнюю часть плиты литосферы Земли, которую в результате тектонической субдукции затянуло более чем на 650 км под северо-восток Китая. Конвекция мантии приводит в движение тектонические плиты Земли, жесткие взаимосвязанные части земной поверхности, которые находятся в постоянном движении, плавая над астеносферой, самым верхним слоем мантии. Там, где тектонические плиты сталкиваются, они высвобождают сейсмическую энергию. Сейсмологи из Университета Райса проанализировали более 67000 измерений, собранных с 313 региональных сейсмических станций на северо-востоке Китая. Эти отверстия также могут объяснить появление вулканов, таких как Чанбайшань, на границе между Китаем и Северной Кореей.
