Slashdot: Voyager 1 is Running Out of Power. NASA Just Switch Part of It Off

Voyager 1 is Running Out of Power. NASA Just Switch Part of It Off Published on 2026-04-19T23:49:00Z After 49 years of space travel, Voyager 1 "is running out of power," reports NPR: The spacecraft runs on a radioisotope thermoelectric generator — a device that converts heat from decaying plutonium into electricity. It carries no solar panels, no rechargeable batteries. Just the slow, steady release of nuclear warmth, which diminishes by about 4 watts each year. After nearly five decades, that decline has become critical. During a routine maneuver in late February, Voyager 1's power levels fell unexpectedly, bringing the probe dangerously close to triggering an automatic fault-protection shutdown — a self-preservation response that would have forced engineers into a lengthy and risky recovery process. The team needed to act first. On April 17, mission engineers sent a sequence of commands to deactivate the Low-energy Charged Particles experiment, known as the LECP, whic...

Slashdot: Nobel Prize-Winning Physicist Predicts Humankind Won't Survive Another 50 Years

Nobel Prize-Winning Physicist Predicts Humankind Won't Survive Another 50 Years Published on 2026-04-19T21:57:00Z Live Science spoke with physicist David Gross, who today received the $3 million "Special Breakthrough Prize in Fundamental Physics". He was part of a trio that won the 2004 physics Nobel prize for research that helped complete the Standard Model of particle physics. But when asked if physics will reach a unified theory of the fundamental forces of nature within 50 years, Gross has a surprising answer. "Currently, I spend part of my time trying to tell people... that the chances of you living 50 [more] years are very small." Cold War estimates for a 1% chance of nuclear war each year seem low, Gross says. "The chances are more likely 2%. So that's a 1-in-50 chance every year." David Gross: The expected lifetime, in the case of 2% [per year], is about 35 years. [The expected lifetime is the average time it would take to have had a nucl...

Slashdot: Is the Iran War Driving a Surge of Interest in Electric Cars?

Is the Iran War Driving a Surge of Interest in Electric Cars? Published on 2026-04-19T19:34:00Z In October and through November, America's EV sales reached their lowest point since 2022 after government subsidies expired, remembers Time. "But first-quarter data for 2026 shows that used EV sales were 12% higher than the same time last year and 17% higher than the previous quarter. "One factor likely helping push buyers toward these cars is high gas prices, which recently topped $4.00 a gallon for the first time in four years," they write — but it's not just in the U.S. Instead, they argue the conflict "is driving a global surge of interest in electric vehicles..." In the U.K., electric car sales reached a record high, with 86,120 vehicles sold in March... The French online used-car retailer Aramisauto reported its share of EV sales nearly doubled from February 16 to March 9, rising to 12.7% from 6.5%, while sales of fueled models dropped to 28% of sale...

Slashdot: Pancreatic Cancer MRNA Vaccine Shows Lasting Results In Early Trial

Pancreatic Cancer MRNA Vaccine Shows Lasting Results In Early Trial Published on 2026-04-19T18:34:00Z NBC News reports on a 16-person clinical trial of "personalized messenger RNA vaccines" which use the immune system to fight cancer cells. "The goal is not to eliminate existing tumors, but instead to stamp out lingering, undetected cancer cells, and later any new cells that form before they can cause a recurrence." Patients still have surgery to remove tumors. After that, the mRNA vaccines are personalized for each individual using genetic material taken from their unique tumor cells. In the clinical trial, after getting the vaccine, the patients also received chemotherapy, which is standard post-op treatment for operable pancreatic cancer... [The article notes that less than 13% of people diagnosed with pancreatic cancer live for more than five years, making it "one of the deadliest cancers."] [E]xperts have long believed that people with pancreatic ca...

Slashdot: Old Cars 'Tell Tales' by Storing Data That's Never Wiped

Old Cars 'Tell Tales' by Storing Data That's Never Wiped Published on 2026-04-18T21:34:00Z Slashdot reader Bismillah shared this report from ITNews: Research and development engineer Romain Marchand of Paris headquartered Quarkslab obtained a telematic control unit (TCU) from a salvage yard in Poland... Marchand tore down the TCU, which is based on a Qualcomm system on a chip, and extracted the Linux-based file system from the Micron multi-chip package (MCP) which contained NAND-based non-volatile storage memory. The non-volatile storage contained sensitive information, including system configuration data and more importantly, logs that revealed the vehicle's GPS positions over time. None of that information was encrypted, Marchand told iTnews, which made it possible to collect and retrieve sensitive data of interest. What's more, the global navigation satellite system (GNSS) logs with GPS positions covered the BYD's full journey from the factory in China to i...

Slashdot: Fewer US College Students Major in CS. More Choose Data Science, Engineering

Fewer US College Students Major in CS. More Choose Data Science, Engineering Published on 2026-04-18T20:34:00Z "From 2008 to 2024, the number of four-year computer science degrees granted rose about fivefold..." reports the Washington Post. Then in 2025 CS suddenly dropped from the fourth-largest undergraduate major to sixth, they report (citing data from the nonprofit National Student Clearinghouse, which compiles numbers from 97% of U.S. universities. The 54,000-student drop was "the biggest one-year drop of any major discipline going back to at least 2020." But what major are they choosing instead? Sarah Karamarkovich, a research associate with the National Student Clearinghouse, pointed to an explanation from the data that we had overlooked. Enrollments in two interdisciplinary majors, data analytics and data science, topped a combined 35,000 in the fall of 2025. That was up from a few hundred when those disciplines were broken out into their own majors in 202...

Slashdot: US Congress Fails to Pass Long-Term FISA Extension, Authorizes It Through April 30

US Congress Fails to Pass Long-Term FISA Extension, Authorizes It Through April 30 Published on 2026-04-18T19:34:00Z Yesterday the U.S. Congress approved "a short-term extension" of a FISA law that allows wiretaps without a warrant for surveilling foreign targets, reports CNN — but only until April 30. Republican congressional leaders had sought an 18-month extension, but "failed to secure" the votes after "clamoring from some of their members for reforms to protect Americans' privacy." The warrantless surveillance law, known as Section 702 of the Foreign Intelligence Surveillance Act, was set to expire on Monday night. Members are hoping the additional time will allow them to come to agreement without ending authorization for the intelligence gathering program, which permits US officials to monitor phone calls and text messages from foreign targets... There was an hour of suspense in the Senate Friday morning when it appeared possible that Democrati...
