Pebblebee is adding a free, helpful feature to already-purchased devices.
Today, it announced that its Clip Universal Bluetooth trackers, which are compatible with iOS and Android devices, are being updated to include an Alert feature that sets off a siren and strobing light when a user wants help.
Pebblebee started selling Android trackers in May 2024 in three different form factors: an AirTag-like Clip version, a credit card-shaped Card SKU, and the smallest version, Tag. In October 2024, Pebblebee announced Universal versions of those trackers that can use both Google’s Find My Device and Apple’s Find My networks (although not simultaneously).

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new black hole that is 225 times more massive than our Sun. The results were presented at the Edoardo Amaldi Conference on Gravitational Waves in Glasgow, Scotland.
The LIGO/Virgo/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. LIGO detects gravitational waves via laser interferometry, using high-powered lasers to measure tiny changes in the distance between two objects positioned kilometers apart. LIGO has detectors in Hanford, Washington, and in Livingston, Louisiana. A third detector in Italy, Advanced Virgo, came online in 2016. In Japan, KAGRA is the first gravitational-wave detector in Asia and the first to be built underground. Construction began on LIGO-India in 2021, and physicists expect it will turn on sometime after 2025.
To date, the collaboration has detected dozens of merger events since its first Nobel Prize-winning discovery. Early detected mergers involved either two black holes or two neutron stars. In 2021, LIGO/Virgo/KAGRA confirmed the detection of two separate "mixed" mergers between black holes and neutron stars.

Reddit announced today that it has started verifying UK users' ages before letting them "view certain mature content" in order to comply with the country's Online Safety Act.
Reddit said that users "shouldn't need to share personal information to participate in meaningful discussions," but that it will comply with the law by verifying age in a way that protects users' privacy. "Using Reddit has never required disclosing your real world identity, and these updates don't change that," Reddit said.
Reddit said it contracted with the company Persona, which "performs the verification on either an uploaded selfie or a photo of your government ID. Reddit will not have access to the uploaded photo, and Reddit will only store your verification status along with the birthdate you provided so you won't have to re-enter it each time you try to access restricted content."

When it comes to concrete use cases for large language models, AI companies love to point out the ways coders and software developers can use these models to increase their productivity and overall efficiency in creating computer code. However, a new randomized controlled trial has found that experienced open source coders became less efficient at coding-related tasks when they used current AI tools.
For their study, researchers at METR (Model Evaluation and Threat Research) recruited 16 software developers, each with multiple years of experience working on specific open source repositories. The study followed these developers across 246 individual "tasks" involved with maintaining those repos, such as "bug fixes, features, and refactors that would normally be part of their regular work." For half of those tasks, the developers used AI tools like Cursor Pro or Anthropic's Claude; for the others, the programmers were instructed not to use AI assistance. Expected time forecasts for each task (made before the groupings were assigned) were used as a proxy to balance out the overall difficulty of the tasks in each experimental group, and the time needed to fix pull requests based on reviewer feedback was included in the overall assessment.
Experts and the developers themselves expected time savings that didn't materialize when AI tools were actually used.

Before performing the study, the developers in question expected the AI tools would lead to a 24 percent reduction in the time needed for their assigned tasks. Even after completing those tasks, the developers believed that the AI tools had made them 20 percent faster, on average. In reality, though, the AI-aided tasks ended up being completed 19 percent slower than those completed without AI tools.

Nvidia is recommending a mitigation for customers of one of its GPU product lines that will degrade performance by up to 10 percent in a bid to protect users from exploits that could let hackers sabotage work projects and possibly cause other compromises.
The move comes in response to an attack a team of academic researchers demonstrated against Nvidia’s RTX A6000, a widely used GPU for high-performance computing that’s available from many cloud services. A vulnerability the researchers discovered opens the GPU to Rowhammer, a class of attack that exploits physical weakness in DRAM chip modules that store data.
Rowhammer allows hackers to change or corrupt data stored in memory by rapidly and repeatedly accessing—or hammering—a physical row of memory cells. By repeatedly hammering carefully chosen rows, the attack induces bit flips in nearby rows, meaning a digital zero is converted to a one or vice versa. Until now, Rowhammer attacks have been demonstrated only against memory chips for CPUs, used for general computing tasks.

A Utah-based plastic surgeon appears to be off the hook for federal charges over an alleged COVID-19 vaccine fraud scheme, in which he and three of his associates were accused of providing fraudulent COVID-19 vaccination cards at $50 a pop while squirting the corresponding vaccines down the drain—wasting roughly $28,000 worth of federally provided, lifesaving vaccines. In cases where parents brought in children for fake immunizations, the group would allegedly inject saline solutions at the parents' request to make the children believe they had received vaccinations.
In total, the group was accused of wasting 1,937 COVID-19 vaccine doses between October 2021 and September 2022, including 391 pediatric doses, and creating fraudulent immunization records for them. The alleged scheme netted them nearly $97,000.
The charges were filed in January 2023 under the Biden administration after two separate undercover agents went through the scheme to get a fake vaccination card. The plastic surgeon, Michael Kirk Moore Jr., who owns and operates Plastic Surgery Institute of Utah in Midvale, south of Salt Lake City, as well as the business' office manager, Kari Dee Burgoyne, its receptionist, Sandra Flores, and Moore's neighbor, Kristin Jackson Andersen, were charged in the case. All four people faced charges of conspiracy to defraud the federal government, along with two counts related to improper disposal of government property.
