Researcher and amateur astronomer Worahate Boonprod tracked 3I/ATLAS using GOES-19 weather satellite data. (Image credit: Image: CCOR-1/GOES-19/NOAA. Processed and annotated by Worachate Boonplod.)Observations by the spacecraft revealed that Comet 3I/ATLAS is rapidly increasing in brightness as it wobbles behind the Sun.The comet is flying around the sun, obscuring it from Earth’s view, to reach perihelion (the closest point to our star) on Thursday (October 29).But while much of the world waits for its reappearance, some researchers and amateur astronomers are using probes to track its path. you may like On October 18, amateur astronomer and veteran comet spotter Worakate Boonplod…
Astronomers have discovered a surprisingly lopsided disk surrounding the nearby mysterious star Beta Canis Majoris, thanks to a brand new ‘photonic lantern’ device that could significantly improve the observation capabilities of ground-based telescopes.Beta Canis Minor, also known as Gomeisa, is about 3.5 times the mass of the Sun and is located about 162 light-years from Earth in the constellation Canis Minor, where it is visible to the naked eye at night. Despite its relative proximity to Earth, researchers still don’t know much about it. For example, past studies have suggested that this is a close binary system consisting of two…
Most people currently tracking their health have scattered clues. Their smart watches display their sleep time. Fitness apps track your steps. Nutrition management app calculates calories. But there are few tools that can help you understand how it all fits together. New York-based startup Bevel believes that’s the missing piece in the move toward preventive health. The company has raised $10 million in Series A from General Catalyst to expand its AI Health Companion, which integrates data from wearables and daily habits into personalized insights across sleep, fitness, and nutrition. The investment follows a breakout year for the two-year-old health…
A solar storm comparable to the infamous Carrington event could wipe out all the satellites orbiting Earth, leaving us in an unstable and costly predicament, according to an alarming new simulation. And experts say such powerful solar storms are inevitable and will hit Earth sooner or later.On September 1, 1859, British astronomer Richard Carrington observed a brilliant flash of light emanating from a giant sunspot, about the size of Jupiter. He had witnessed the most powerful solar flare in recorded history, followed by a major disruption to the Earth’s magnetic field known as a geomagnetic storm that raged for almost…
October 30, 2025Ravi LakshmananBrowser security/vulnerabilities A serious vulnerability disclosed in Chromium’s Blink rendering engine could cause many Chromium-based browsers to crash within seconds. Security researcher Jose Pino, who detailed the flaw, code-named it “Brash.” “By exploiting an architectural flaw in how certain DOM operations are managed, any Chromium browser can collapse in 15 to 60 seconds,” Pino said of the technical details of the flaw. The core of Brash lies in the lack of rate limiting on updates to the “document.title” API, resulting in millions of possible attacks. [document object model] Mutations per second not only crashes the web browser…
Early research suggests that “chemobrain” – difficulties with concentration, thinking and memory caused by chemotherapy – may be caused by the destruction of the brain’s lymphatic system caused by cancer treatment.This study focused on the meningeal lymphatic vessels, a drainage network found in the protective tissue layers surrounding the brain. Dysfunction of this network is associated with Alzheimer’s disease, Parkinson’s disease, and traumatic brain injury.Now, a new study published Oct. 13 in the journal Communications Biology has linked damage to the meningeal lymphatic vessels to the brain fog that patients often experience after undergoing chemotherapy. you may like Using human…
A new study shows that tectonic movements and the “ghosts” of past ice sheets are warping, lifting and pulling Greenland in different directions.Greenland sits on top of the North American tectonic plate, which has dragged the island northwest by 0.9 inches (23 millimeters) per year for the past 20 years. Researchers have been monitoring this drift for some time, but a new study analyzing satellite data shows there’s much more to this movement and other deformations than plate tectonics.”The torsion, pressure and tension give rise to this complex pattern,” says study lead author Danjal Longfors Berg, a postdoctoral researcher specializing…
More and more people are turning to AI instead of Google to discover products. This holiday season, Americans are more likely to rely on large-scale language models to find gifts, sales, and deals, rather than traditional search, according to a recent shopping report. According to the report, retailers could see up to 520% more traffic from chatbots and AI prompts in 2025 compared to 2024. For brands, that means quickly figuring out how to appear in AI-generated recommendations. This AI-driven traffic surge is the bet behind The Prompting Company, a YC-backed startup that helps products get mentioned within AI apps…
Security does not fail at the point of breach. It fails at the moment of impact. This sentence set the tone for this year’s Picus Breach and Simulation (BAS) Summit. There, researchers, practitioners, and CISOs all echoed the same theme: Cyber defense is no longer about prediction. It’s about the evidence. When a new exploit is dropped, scanners search the internet within minutes. Once the attacker gains a foothold, lateral movement often follows just as quickly. If your controls aren’t tested against the exact technique you’re playing, you’re not defending and hoping things don’t go seriously pear-shaped. This is why…
Learn how the U.S. Environmental Protection Agency (EPA) is strengthening national and international efforts to combat PFAS pollution through science-based regulations, global partnerships, community support, and innovative technologies to protect human health and the environment. EPA is committed to combating per- and polyfluoroalkyl substances (PFAS) pollution. This work is guided by the principles of strengthening science, meeting legal obligations, strengthening communication and building partnerships. Advancing scientific understanding through PFAS testing strategies In April 2025, the agency announced it would implement a PFAS testing strategy under TSCA Section 4, requiring scientific information informed by hazard characteristics and routes of exposure. EPA…
