Slashdot: Deep Sleep May Help the Brain Clear Alzheimer's Toxins

Deep Sleep May Help the Brain Clear Alzheimer's Toxins
Published on November 01, 2019 at 09:00AM
An anonymous reader quotes a report from NPR: The brain waves generated during deep sleep appear to trigger a cleaning system in the brain that protects it against Alzheimer's and other neurodegenerative diseases. Electrical signals known as slow waves appear just before a pulse of fluid washes through the brain, presumably removing toxins associated with Alzheimer's, researchers reported Thursday in the journal Science. The finding could help explain a puzzling link between sleep and Alzheimer's, says Laura Lewis, an author of the study and an assistant professor in the department of biomedical engineering at Boston University. The finding also suggests that people might be able to reduce their risk of Alzheimer's by ensuring that they get high-quality sleep, says William Jagust, a professor of public health and neuroscience at the University of California, Berkeley, who was not involved in the study.

Slashdot: AT&T Says Leaked Data of 70 Million People Is Not From Its Systems

AT&T Says Leaked Data of 70 Million People Is Not From Its Systems Published on March 20, 2024 at 02:15AM An anonymous reader quotes a report from BleepingComputer: AT&T says a massive trove of data impacting 71 million people did not originate from its systems after a hacker leaked it on a cybercrime forum and claimed it was stolen in a 2021 breach of the company. While BleepingComputer has not been able to confirm the legitimacy of all the data in the database, we have confirmed some of the entries are accurate, including those whose data is not publicly accessible for scraping. The data is from an alleged 2021 AT&T data breach that a threat actor known as ShinyHunters attempted to sell on the RaidForums data theft forum for a starting price of $200,000 and incremental offers of $30,000. The hacker stated they would sell it immediately for $1 million. AT&T told BleepingComputer then that the data did not originate from them and that its systems were not breached. &q

Slashdot: AT&T, T-Mobile Prep First RedCap 5G IoT Devices

AT&T, T-Mobile Prep First RedCap 5G IoT Devices Published on October 15, 2024 at 03:20AM The first 5G Internet of Things (IoT) devices are launching soon. According to Fierce Wireless, T-Mobile plans to launch its first RedCap devices by the end of the year, while AT&T's devices are expected sometime in 2025. From the report: All of this should pave the way for higher performance 5G gadgets to make an impact in the world of IoT. RedCap, which stands for reduced capabilities, was introduced as part of the 3GPP's Release 17 5G standard, which was completed -- or frozen in 3GPP terms -- in mid-2022. The specification, which is also called NR-Light, is the first 5G-specific spec for IoT. RedCap promises to offer data transfer speeds of between 30 Mbps to 80 Mbps. The RedCap spec greatly reduces the bandwidth needed for 5G, allowing the signal to run in a 20 MHz channel rather than the 100 MHz channel required for full scale 5G communications.

Slashdot: AT&T Can't Hang Up On Landline Phone Customers, California Agency Rules

AT&T Can't Hang Up On Landline Phone Customers, California Agency Rules Published on June 22, 2024 at 01:50AM An anonymous reader quotes a report from Ars Technica: The California Public Utilities Commission (CPUC) yesterday rejected AT&T's request to end its landline phone obligations. The state agency also urged AT&T to upgrade copper facilities to fiber instead of trying to shut down the outdated portions of its network. AT&T asked the state to eliminate its Carrier of Last Resort (COLR) obligation, which requires it to provide landline telephone service to any potential customer in its service territory. A CPUC administrative law judge recommended rejection of the application last month, and the commission voted to dismiss AT&T's application with prejudice on Thursday. "Our vote to dismiss AT&T's application made clear that we will protect customer access to basic telephone service... Our rules were designed to provide that assurance,
