Researchers at the University of Southern California say they've developed a memristor memory device that continued operating at 700 degrees Celsius. "And crucially, 700 degrees was not the limit, it was simply as hot as their testing equipment could go," adds ScienceAlert. "The device showed no signs of failing." From the report: The device is called a memristor and it's a nanoscale component that can both store information and perform computing operations. Think of it as a tiny sandwich with two electrode layers on the outside and a thin ceramic filling in the middle. The team built theirs from tungsten, the metal with the highest melting point of any element, combined with a ceramic called hafnium oxide, and with a layer of graphene at the bottom. Each material can withstand enormous heat. Together, they turned out to be extraordinary. What makes graphene the key ingredient is the way it interacts with tungsten at the atomic level. In a conventional device, heat causes metal atoms to drift slowly through the ceramic layer until they bridge the two electrodes, short circuiting everything and leaving the device permanently broken. Graphene stops that process dead. Its surface chemistry with tungsten is ... almost like oil and water. Tungsten atoms that drift toward the graphene find they simply cannot take hold, no anchor, no short circuit, no failure. The team used advanced electron microscopy and quantum level computer simulations to understand exactly why, turning a single lucky result into a repeatable principle. The findings have been published in the journal Science.

J. Allen Hynek started as an Air Force consultant brought in to help explain away early UFO reports, but over time he grew frustrated with what he saw as the government's effort to minimize unexplained cases rather than seriously investigate them. Longtime Slashdot reader schwit1 shares an article from Popular Mechanics, in collaboration with Biography.com, that argues Hynek's shift from skeptic to advocate helped shape modern ufology, and that the Air Force's attempts to control the narrative may have deepened the public distrust and conspiracy thinking that followed. From the report: Do you think the U.S. government is hiding, and possibly reverse-engineering, extraterrestrial technology? Think again. Or better yet, don't think about it at all. Nothing to see here. That's the underlying message of a report released in 2024 by the Department of Defense. The 63-page "Report on the Historical Record of U.S. Government Involvement with Unidentified Anomalous Phenomena (UAP) " concludes that the DoD's All-Domain Anomaly Resolution Office (AARO) "found no evidence that any [U.S. Government] investigation, academic-sponsored research, or official review panel has confirmed that any sighting of a UAP represented extraterrestrial technology." The AARO, as The Guardian summarizes, is "a government office established in 2022 to detect and, as necessary, mitigate threats including 'anomalous, unidentified space, airborne, submerged and transmedium objects.'" This report came on the heels of, and in contradiction to, what was arguably the most high-profile hearing on UAPs -- formerly known as unidentified flying objects, or UFOs -- in decades: the August 2023 testimony of "whistleblower" Dave Grusch. [...] The 2024 AARO report stated that during the time Hynek was working with Project Blue Book [the U.S. Air Force's best-known UFO investigation program], "about 75 percent of Americans trusted the [US government] 'to do the right thing almost always or most of the time.'" But, the report noted, since 2007, that number has never risen above 30 percent. "This lack of trust probably has contributed to the belief held by some subset of the U.S. population that the USG has not been truthful regarding knowledge of extraterrestrial craft." Ultimately, the Air Force's efforts to stifle Hynek -- pressuring him to offer the public standard responses to questions he wasn't even allowed to ask -- appears to have backfired. Ironically, the Air Force's attempts to quiet suspicions only fueled them, leading to more conspiracy theories and distrust. People came to believe that the government was hiding the truth, contrary to Hynek's actual revelation: that, in reality, the people at the top may not care much about finding the answers after all.

BrianFagioli shares a report from NERDS.xyz: For years pop culture has treated April 25 as the "perfect date," thanks to the famous Miss Congeniality line about needing only a light jacket. But new analysis from WeatherBug suggests that idea does not actually hold up when you look at the numbers. After reviewing U.S. weather data from 2018 through today, the company concluded that October 8 delivers the most reliable combination of comfortable temperatures and low rainfall nationwide. According to the analysis, the average conditions on that day land around 66F with just 0.0573 inches of precipitation. The study used population weighted weather data drawn from roughly 20 million daily WeatherBug users across the United States. When the company compared all days of the year, April 25 ranked only 80th, averaging about 60F and roughly 0.1297 inches of rain. The broader dataset also shows July dominating the hottest days of the year while January owns the coldest, with January 20 averaging just 33F nationally. While no single date guarantees perfect weather everywhere in a country as large as the U.S., the numbers suggest early October may quietly offer one of the most reliable windows for comfortable outdoor conditions.
