AI-based tool predicts future cardiovascular events in patients with angina

Reduced coronary blood flow, measured with an artificial intelligence-based imaging tool, predicted future cardiovascular events in patients with suspected stable coronary artery disease. These findings were presented at EACVI 2025, the congress of the European Association of Cardiovascular Imaging (EACVI).

Stable coronary artery disease (CAD) refers to the common syndrome of recurrent, transient episodes of chest symptoms, often manifesting as angina. Coronary computed tomography angiography (CCTA) is a noninvasive heart scan that is used as the first-line investigation for patients with suspected stable CAD.

AI tools and FFR-CT explained While CCTA clearly shows blockages in coronary arteries, it is limited in its ability to estimate reduced blood flow, which is necessary to diagnose angina. An artificial intelligence-based tool has been developed that analyzes CCTA images and provides an estimate of blood flow, termed CT-derived fractional flow reserve (FFR-CT).

AI Bathroom Monitors? Welcome To America’s New Surveillance High Schools

This isn’t a high-security government facility. It’s Beverly Hills High School.

District superintendent Alex Cherniss says the striking array of surveillance tools is a necessity, and one that ensures the safety of his students. “We are in the hub of an urban setting of Los Angeles, in one of the most recognizable cities on the planet. So we are always a target and that means our kids are a target and our staff are a target,” he said. In the 2024–2025 fiscal year, the district spent $4.8 million on security, including staff. The surveillance system spots multiple threats per day, the district said.

Beverly Hills’ apparatus might seem extreme, but it’s not an outlier. Across the U.S., schools are rolling out similar surveillance systems they hope will keep them free of the horrific and unceasing tide of mass shootings. There have been 49 deaths from gunfire on school property this year. In 2024, there were 59, and in 2023 there were 45, per Everytown for Gun Safety. Between 2000 and 2,022,131 people were killed and 197 wounded at schools in the U.S., most of them children. Given those appalling metrics, allocating a portion of your budget to state of the art AI-powered safety and surveillance tools is a relatively easy decision.

Inside SpaceX’s Pre-IPO Share Buyback and Who Gets Access

SpaceX is preparing for a potential IPO by buying back shares from institutional holders and allowing existing shareholders to sell shares, while its affiliate company Tesla is making progress in autonomous driving technology with plans to launch robo-taxis in multiple cities ## Questions to inspire discussion.

SpaceX Investment Access.

🔐 Q: How can individual investors access SpaceX shares before the IPO?

A: Investors must be accredited with liquid net worth over $1M (excluding home) and can access shares through special purpose vehicles (SPVs) that charge upfront fees and 10% carry on returns.

💰 Q: What is the minimum investment required to buy SpaceX shares directly?

A: Direct SpaceX share purchases require $50M-$1B investments due to SEC’s 2,000 shareholder cap for private companies, making SPVs the only option for smaller investors.

Russia-Linked Hackers Use Microsoft 365 Device Code Phishing for Account Takeovers

A suspected Russia-aligned group has been attributed to a phishing campaign that employs device code authentication workflows to steal victims’ Microsoft 365 credentials and conduct account takeover attacks.

The activity, ongoing since September 2025, is being tracked by Proofpoint under the moniker UNK_AcademicFlare.

The attacks involve using compromised email addresses belonging to government and military organizations to strike entities within government, think tanks, higher education, and transportation sectors in the U.S. and Europe.

Texas sues TV makers for taking screenshots of what people watch

The Texas Attorney General sued five major television manufacturers, accusing them of illegally collecting their users’ data by secretly recording what they watch using Automated Content Recognition (ACR) technology.

The lawsuits target Sony, Samsung, LG, and China-based companies Hisense and TCL Technology Group Corporation. Attorney General Ken Paxton’s office also highlighted “serious concerns” about the two Chinese companies being required to follow China’s National Security Law, which could give the Chinese government access to U.S. consumers’ data.

According to complaints filed this Monday in Texas state courts, the TV makers can allegedly use ACR technology to capture screenshots of television displays every 500 milliseconds, monitor the users’ viewing activity in real time, and send this information back to the companies’ servers without the users’ knowledge or consent.

Winter virus season so far is not too bad, but doctors worry about suffering to come

It may feel like you are surrounded by sniffles and coughs, but flu season activity is still low in many parts of the U.S.

New government data posted Friday shows that as of last week, flu activity was high in four states—Colorado, Louisiana, New Jersey and New York—and minimal or low in most others. Severity indicators are increasing but are still within the boundaries of a “mild” season, said officials at the U.S. Centers for Disease Control and Prevention.

A number of diseases tend to peak in the winter, thanks to indoor gatherings that help germs spread. The list includes not only colds and flu but also norovirus—a highly infectious cause of vomiting and diarrhea. Norovirus cases have generally been trending up in the last month.

Nvidia can sell the more advanced H200 AI chip to China — but will Beijing want them?

Nvidia has approval from the U.S. government to sell its more advanced H200 AI chips to China. But the question is whether Beijing wants it or will let companies buy it.

The company can now ship its H200 chip to “approved customers”, provided the U.S. government gets a 25% cut of those sales. It had been effectively banned from selling any semiconductors to China earlier this year, but since July sought to resume H20 sales, a less advanced chip designed specifically to comply with export restrictions.

Reports had suggested Beijing prohibited local companies from buying the H20. Nvidia is not baking in huge China sales into its forecasts as a result. After the ban was lifted, the Financial Times reported China would “limit access” to the H200, citing unidentified sources.
