Inside the marketplace for vaccine medical exemptions

2025-11-01 19:15:57

Maybe a client hears about them in the comment section of the Facebook group “Medical Exemption Accepted,” or on the r/unvaccinated forum on Reddit. Maybe it’s through an interview posted on the video-sharing platform Rumble. Or maybe it’s the targeted advertisements on Google: “We do medical exemptions.”

Cassandra Clerkin, a mother in upstate New York, first got in touch with Frontline Health Advocates near the start of the 2024–2025 school year, after hearing they had doctors who would write exemptions from school immunization requirements. One of Clerkin’s children, she said, had suffered seizures after receiving a vaccine. The family didn’t want more shots. But New York has some of the country’s strictest school immunization policies.

Perhaps Frontline could help.

YouTube denies AI was involved with odd removals of tech tutorials

2025-11-01 08:32:01

This week, tech content creators began to suspect that AI was making it harder to share some of the most highly sought-after tech tutorials on YouTube, but now YouTube is denying that odd removals were due to automation.

Creators grew alarmed when educational videos that YouTube had allowed for years were suddenly being bizarrely flagged as “dangerous” or “harmful,” with seemingly no way to trigger human review to overturn removals. AI seemed to be running the show, with creators’ appeals seemingly getting denied faster than a human could possibly review them.

Late Friday, a YouTube spokesperson confirmed that videos flagged by Ars have been reinstated, promising that YouTube will take steps to ensure that similar content isn’t removed in the future. But, to creators, it remains unclear why the videos got taken down, as YouTube claimed that both initial enforcement decisions and decisions on appeals were not the result of an automation issue.

Neural network finds an enzyme that can break down polyurethane

2025-11-01 06:35:50

You’ll often hear plastic pollution referred to as a problem. But the reality is that it’s multiple problems. Depending on the properties we need, we form plastics out of different polymers, each of which is held together by a distinct type of chemical bond. So the method we use to break down one type of polymer may be incompatible with the chemistry of another.

That problem is why, even though we’ve had success finding enzymes that break down common plastics like polyesters and PET, they’re only partial solutions to plastic waste. However, researchers aren’t sitting back and basking in the triumph of partial solutions, and they’ve now got very sophisticated protein design tools to help them out.

That’s the story behind a completely new enzyme that researchers developed to break down polyurethane, the polymer commonly used to make foam cushioning, among other things. The new enzyme is compatible with an industrial-style recycling process that breaks the polymer down into its basic building blocks, which can be used to form fresh polyurethane.

Cursor introduces its coding model alongside multi-agent interface

2025-11-01 05:34:16

Cursor has for the first time introduced what it claims is a competitive coding model, alongside the 2.0 version of its integrated development environment (IDE) with a new feature that allows running tasks with multiple agents in parallel.

The company’s flagship product is an IDE modeled after Visual Studio Code in many respects, but with a strong emphasis on vibe coding and heavier direct integration of large language model-based tools in the interface and workflow. Since its introduction, Cursor has supported models developed by other companies such as OpenAI, Google, and Anthropic. However, while it has trialed its own built-in models, they weren’t competitive with the big frontier models.

It’s a different story now, according to the company’s claims about Composer. Built with reinforcement learning and a mixture-of-experts architecture, Composer is dubbed by Cursor “a frontier model that is 4x faster than similarly intelligent models”—a significant claim when you consider what it’s competing with.

Two Windows vulnerabilities, one a 0-day, are under active exploitation

2025-11-01 05:03:56

Two Windows vulnerabilities—one a zero-day that has been known to attackers since 2017 and the other a critical flaw that Microsoft initially tried and failed to patch recently—are under active exploitation in widespread attacks targeting a swath of the Internet, researchers say.

The zero-day went undiscovered until March, when security firm Trend Micro said it had been under active exploitation since 2017, by as many as 11 separate advanced persistent threats (APTs). These APT groups, often with ties to nation-states, relentlessly attack specific individuals or groups of interest. Trend Micro went on to say that the groups were exploiting the vulnerability, then tracked as ZDI-CAN-25373, to install various known post-exploitation payloads on infrastructure located in nearly 60 countries, with the US, Canada, Russia, and Korea being the most common.

A large-scale, coordinated operation

Seven months later, Microsoft still hasn’t patched the vulnerability, which stems from a bug in the Windows Shortcut binary format. The Windows component makes opening apps or accessing files easier and faster by allowing a single binary file to invoke them without having to navigate to their locations. In recent months, the ZDI-CAN-25373 tracking designation has been changed to CVE-2025-9491.

FCC to rescind ruling that said ISPs are required to secure their networks

2025-11-01 04:44:19

The Federal Communications Commission will vote in November to repeal a ruling that requires telecom providers to secure their networks, acting on a request from the biggest lobby groups representing Internet providers.

FCC Chairman Brendan Carr said the ruling, adopted in January just before Republicans gained majority control of the commission, “exceeded the agency’s authority and did not present an effective or agile response to the relevant cybersecurity threats.” Carr said the vote scheduled for November 20 comes after “extensive FCC engagement with carriers” who have taken “substantial steps… to strengthen their cybersecurity defenses.”

The FCC’s January 2025 declaratory ruling came in response to attacks by China, including the Salt Typhoon infiltration of major telecom providers such as Verizon and AT&T. The Biden-era FCC found that the Communications Assistance for Law Enforcement Act (CALEA), a 1994 law, “affirmatively requires telecommunications carriers to secure their networks from unlawful access or interception of communications.”
