AI predicts material properties using electron-level information without costly quantum mechanical computations

Researchers in Korea have developed an artificial intelligence (AI) technology that predicts molecular properties by learning electron-level information without requiring costly quantum mechanical calculations. The research was presented at ICLR 2025.

A joint research team led by Senior Researcher Gyoung S. Na from the Korea Research Institute of Chemical Technology (KRICT) and Professor Chanyoung Park from the Korea Advanced Institute of Science and Technology (KAIST) has developed a novel AI method—called DELID (Decomposition-supervised Electron-Level Information Diffusion)—that accurately predicts using electron-level information without performing quantum mechanical computations.

The method achieved state-of-the-art prediction accuracy on real-world datasets consisting of approximately 30,000 experimental molecular data.

Sonic Booms in the Sky: How Scientists Use “Bolides” To Improve Planetary Defense

Faint booms from space help track incoming debris. But the path matters more than you think. Earth gains a little mass each year as space dust rains down from above, adding thousands of metric tons to the planet’s surface. In addition, roughly 50 tons of meteorites fall to Earth annually. Since t

Critical Cisco Vulnerability in Unified CM Grants Root Access via Static Credentials

The networking equipment major said it found no evidence of the flaw being exploited in the wild, and that it was discovered during internal security testing.

CVE-2025–20309 affects Unified CM and Unified CM SME versions 15.0.1.13010–1 through 15.0.1.13017–1, irrespective of device configuration.

Hackers Using PDFs to Impersonate Microsoft, DocuSign, and More in Callback Phishing Campaigns

Cybersecurity researchers are calling attention to phishing campaigns that impersonate popular brands and trick targets into calling phone numbers operated by threat actors.

“A significant portion of email threats with PDF payloads persuade victims to call adversary-controlled phone numbers, displaying another popular social engineering technique known as Telephone-Oriented Attack Delivery (TOAD), also known as callback phishing,” Cisco Talos researcher Omid Mirzaei said in a report shared with The Hacker News.

An analysis of phishing emails with PDF attachments between May 5 and June 5, 2025, has revealed Microsoft and Docusign to be the most impersonated brands. NortonLifeLock, PayPal, and Geek Squad are among the most impersonated brands in TOAD emails with PDF attachments.

Spain arrests hackers who targeted politicians and journalists

The Spanish police have arrested two individuals in the province of Las Palmas for their alleged involvement in cybercriminal activity, including data theft from the country’s government.

The duo has been described as a “serious threat to national security” and focused their attacks on high-ranking state officials as well as journalists. They leaked samples of the stolen data online to build notoriety and inflate the selling price.

“The investigation began when agents detected the leakage of personal data affecting high-level institutions of the State across various mass communication channels and social networks,” reads the police announcement.

Researchers take major step toward cuff-free blood pressure monitoring

Researchers have shown, for the first time, that speckle contrast optical spectroscopy (SCOS) can be used for cuffless blood pressure monitoring. The new technology could improve early detection and management of hypertension.

“Hypertension affects nearly half of all adults in the US and is the leading cause of cardiovascular disease,” said Ariane Garrett, a doctoral student in Darren Roblyer’s lab at Boston University. “This research is a step toward a that would let people monitor their any time, without a cuff.”

SCOS is a noninvasive imaging technique that measures by analyzing speckle patterns formed by coherent light scattering from cells and tissue. While it has been used for other applications such as brain and tissue monitoring, this is one of the first studies to explore how SCOS signals relate to blood pressure.
