Scientists Just Found a Key Ingredient for Superconductivity at Room Temperature

Researchers have discovered that a key requirement for superconductivity can persist even at room temperature.

Scientists searching for a superconductor that works at room temperature have identified a potential way forward. New research from Utrecht, Leiden, and Munich shows that electrons can form the pairs needed for superconductivity even at room temperature. The findings, published in Science, suggest that a different requirement may be preventing these materials from conducting electricity without resistance.

The key appears to be how paired electrons behave collectively. Although the pairs can survive at much higher temperatures than previously understood, they must also act in a coordinated way for superconductivity to emerge.

EMudhra revokes 8 more CA certificates after private key mishap

Certificate authority eMudhra has revoked eight additional intermediate CA certificates after an investigation into its recent certificate security incident found improper handling of private keys during the certificate-generation process.

The new revocations bring the total number of affected intermediate CA certificates to 16, including eight previously compromised certificates whose private keys were so weak that anyone could recover them almost instantly.

In a new incident report published Tuesday, eMudhra said that both sets of certificates were affected by a custom Python script used to transfer private keys between hardware security modules (HSMs) in April 2025.

Notion says Fireworks breach exposed customer AI chat transcripts

Notion, the digital workspace platform, disclosed that a security breach at its AI infrastructure provider, Fireworks AI, exposed Notion AI chat transcripts in a small number of workspaces.

The disclosure comes shortly after Fireworks AI confirmed that an attacker accessed its development environment via a third-party cloud provider on October 23 and compromised resource metadata, billing information, model weights, and datasets for some customers.

Fireworks AI experienced another breach in early October, when hackers accessed environment variables containing API keys and tokens stored as secrets for a limited number of accounts.

ScreenConnect Attacks Target at Least 288 Endpoints Across 48 Organizations With Rogue Clients

Cybersecurity company Huntress, which is also tracking the activity, said it has observed attackers using access to cloud-hosted ScreenConnect panels to push Run commands with an aim to install rogue ScreenConnect clients on at least 288 managed endpoints across 48 organizations. The activity was first detected on November 11, 2026, at around 5:47 p.m. UTC.

Huntress told The Hacker News that it has not seen evidence of a new vulnerability, but noted the exact method through which the attacker got panel access remains unclear. Current telemetry points to compromised credentials or hijacked operator sessions to gain initial access, it said.

Over 35,000 Grok-Built Apps Exposed Online, Some Leaking Confidential Data and Passwords

No app goes public until its creator clicks Publish. In the paid account the researchers used, the next step offered 3 access settings: “Anyone with the link”, “Invited users” and “Only you”. “Anyone with the link” was already selected.

The setting matters because an app’s address does not stay secret, the researchers say. Opening an app makes the visitor’s computer look up its subdomain in DNS. Passive DNS services record such lookups, and anyone with an account can search those records by pattern.

Grok suggests 4 random words as each app’s name, and about half of the names the researchers found followed that pattern. Such names are hard to guess, but that does not protect an app whose name already sits in a searchable list.

The Rise and Rise of Alice Huang

Alice Huang leveraged her connections from investing in internet video games to become a data center executive. Here are the interlocking arrangements that would put her in Jensen Huang’s orbit.

The revenues of alleged Chinese spy Alice Huang’s online video games company, BVI-registered Osmanthus Vale Holdings Ltd, rose from $36,000 to $36 million in just three years. Then she sold it for $145 million to a Shenzhen firm that would facilitate her entry into the AI data center industry. The Wire China follows the filings.
