Slashdot: Cancer Might Protect Against Alzheimer's

Cancer Might Protect Against Alzheimer's
Published on January 29, 2026 at 01:32AM
For decades, researchers have noted that cancer and Alzheimer's disease are rarely found in the same person, fuelling speculation that one condition might offer some degree of protection from the other. Nature: Now, a study in mice provides a possible molecular solution to the medical mystery: a protein produced by cancer cells seems to infiltrate the brain, where it helps to break apart clumps of misfolded proteins that are often associated with Alzheimer's disease. The study, which was 15 years in the making, was published on 22 January in Cell and could help researchers to design drugs to treat Alzheimer's disease. "They have a piece of the puzzle," says Donald Weaver, a neurologist and chemist at the Krembil Research Institute at the University of Toronto in Canada, who was not involved in the study. "It's not the full picture by any stretch of the imagination. But it's an interesting piece." [...] A 2020 meta-analysis of data from more than 9.6 million people found that cancer diagnosis was associated with an 11% decreased incidence of Alzheimer's disease. It has been a difficult relationship to unpick: researchers must control for a variety of external factors. For example, people might die of cancer before they are old enough to develop symptoms of Alzheimer's disease, and some cancer treatments can cause cognitive difficulties, which could obscure an Alzheimer's diagnosis.

Slashdot: Battery Fires At Recycling Centres Are Costing the UK £1bn a Year

Battery Fires At Recycling Centres Are Costing the UK £1bn a Year Published on 2026-08-23T00:29:00Z Wrongly discarded lithium batteries, such as those in vapes, are causing more than 10 fires a week at U.K. recycling centers, according to figures shared with the Guardian: The Environment Services Association (ESA), the trade body for waste management companies, said its members had reported 1,518 fires in the year to March 2026. At least 541 of these fires were directly attributed to lithium ion batteries, the survey found. There were a further 216 battery fires in bin lorries [garbage trucks]. The ESA said the reported number of battery-related fires underestimated the scale of the problem, because in most incidents it was impossible to determine the cause of the blaze. A spokesperson said: "We know 40% of fires at recycling centres are caused by batteries, but we think the actual number is more like 70%." It estimates that annual cost of these fires has increased from ...

Slashdot: How the FSF Sysadmins are Blocking Botnets with reaction

How the FSF Sysadmins are Blocking Botnets with reaction Published on 2026-07-11T21:47:00Z For nearly two years the Free Software Foundation has been fighting web crawlers (including many aggressively scraping training data for AI models). A botnet controlling about five million IPs hit one system for six months in 2025. Their systems administrator wrote this week that they view these as distributed denial-of-service attacks. How are they fighting back? We noticed patterns in the scrapers that were abnormal, which gave us material for writing regular expressions. Searching for the regular expression then gave us a large lists of IP addresses. Looking up the origin of those IP addresses revealed that some of the crawlers were using botnets of residential IP addresses to scrape faster and avoid detection. We looked for what kinds of botnets might be generating the kind of traffic that we were seeing, and one that we suspected was called the "Vo1d" botnet, comprised of sma...

Slashdot: AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age

AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age Published on 2026-03-10T20:00:00Z AT&T plans to invest more than $250 billion over the next five years to expand U.S. telecom infrastructure for the AI age. The company says it will also hire thousands of technicians while partnering with AST SpaceMobile to extend coverage to remote areas. Reuters reports: Rapid adoption of artificial intelligence, cloud computing and connected devices has prompted telecom operators to invest heavily in fiber and 5G networks as they also seek to fend off intensifying competition from cable broadband providers. AT&T, which has about 110,000 employees in the U.S., said the new hires will help build and maintain its infrastructure. The outlay includes capital expenditure and other spending, the company said. The spending will focus on expanding its fiber and wireless networks, including accelerating deployment of fiber broadband, 5G home internet and satellite co...
