Astronomers have gotten their best view yet of the magnetic fields around the gargantuan black hole at the center of the Milky Way. A new image reveals that the behemoth, named Sagittarius A*, is encircled by highly-ordered magnetic structures, researchers report in two papers published March 27 in the Astrophysical Journal Letters. The features are similar to ones previously seen surrounding the galaxy M87’s supermassive black hole (SN: 3/24/21). Using the Event Horizon Telescope, a global collection of radio telescopes working in tandem, scientists captured polarized light coming from around Sagittarius A*, which lies about 27,000 light-years from Earth (SN:…
Much like squirrels, black-capped chickadees hide their food, keeping track of many thousands of little treasures wedged into cracks or holes in tree bark. When a bird returns to one of their many food caches, a particular set of nerve cells in the memory center of their brains gives a brief flash of activity. When the chickadee goes to another stash, a different combination of neurons lights up. These neural combinations act like bar codes, and identifying them may give key insights into how episodic memories — accounts of specific past events, like what you did on your birthday last…
Melissa Red Hoffman was “feeling really stuck” last summer. A 50-year-old surgeon in Asheville, N.C., Hoffman had been struggling with long COVID since getting infected with the coronavirus two and a half years earlier. “Deafening fatigue” was one of her worst symptoms, she says. “I feel tired behind my eyes from the moment I get up to the moment I go to sleep.” She managed to work part time, but much of her work had shifted to administrative tasks that she did from her couch. “I was really at a point where I had tried so many different things myself,…
Scientists studying rocks in South Africa report evidence for the earliest known earthquake triggered by plate tectonics. The temblor struck more than 3 billion years ago. The rocks preserve telltale signs of ancient submarine landslides that tend to occur in response to giant earthquakes set off by some collisions of slabs of the planet’s crust, geologists Cornel de Ronde and Simon Lamb report February 27 in Geology. Finding evidence of such a giant earthquake so early in Earth’s roughly 4.5-billion-year history throws a spotlight on a hotly debated topic in geology: When did plate tectonics, the constant movements of interlocking pieces…
The enemy continues to produce drones and will intensify attacks with Shahed UAVs, according to Natalia Humeniuk, the head of the joint press center of Ukraine’s Operational Command South. “The assembly (of drones – ed.) takes place continuously. They have production facilities. They even boast that they do it on their own territory, marking the drones we find with the letters of the Russian alphabet. The assembly is carried out systematically. And the fact that the drone attacks have become less massive in recent nights may suggest the necessity for a reorientation, a redistribution of the property they have received…
Dogecoin is correcting gains from the $0.230 zone against the US Dollar. DOGE must stay above the $0.1750 support zone to start a fresh increase. DOGE struggled to stay above $0.225 and corrected gains against the US dollar. The price is trading above the $0.1750 level and the 100 simple moving average (4 hours). There was a break below a key bullish trend line with support at $0.2040 on the 4-hour chart of the DOGE/USD pair (data source from Kraken). The price could restart its increase unless there is a close below the $0.1750 support. Dogecoin Price Approaches Key Support…
To understand the new politics stance and other pro nationals of recent times, we should look to Silicon Valley and the quantified movement of the latest generation. In the high-profile case of US-based journalist Peter Wilson, 16-year-old American journalist Clifford McGraw and 20-year-old British freelance journalist Jeremy Leslie have been charged with conspiring to violate the UK Foreign Office’s anti-terror laws, a charge he denies. On Monday, UK attorney Andy McDonald revealed that he had spoken. “Few worry about catching Covid anymore, as it’s just a matter of time before they do,” says Tea, a teacher at a school for…
