Ultra-low power, fully biodegradable artificial synapse offers record-breaking memory

In Nature Communications, a research team affiliated with UNIST present a fully biodegradable, robust, and energy-efficient artificial synapse that holds great promise for sustainable neuromorphic technologies. Made entirely from eco-friendly materials sourced from nature—such as shells, beans, and plant fibers—this innovation could help address the growing problems of electronic waste and high energy use.

Traditional artificial synapses often struggle with high power consumption and limited lifespan. Led by Professor Hyunhyub Ko from the School of Energy and Chemical Engineering, the team aimed to address these issues by designing a device that mimics the brain’s synapses while being environmentally friendly.

A Long-Standing Spintronics Mystery May Finally Be Solved

A long-standing explanation for magnetoresistance may be incomplete. New evidence suggests a universal interfacial mechanism is at play. A major advance in spintronics came with the discovery of unusual magnetoresistance (UMR). In this effect, the electrical resistance of a heavy metal changes wh

Einstein in a Chip: Hidden Geometry Bends Electrons Like Gravity

A team at UNIGE has uncovered a geometric structure once thought to be purely theoretical at the core of quantum materials, opening the door to major advances in future electronics. How can information be processed almost instantly, or electrical current flow without energy loss? To reach these g

Scientists Solve a Hidden Battery Cracking Mystery That Shortens Lifespan and Raises Fire Risk

A new study shows that promising single-crystal battery materials degrade for reasons scientists hadn’t fully recognized before. Scientists at Argonne National Laboratory and the UChicago Pritzker School of Molecular Engineering (UChicago PME) have identified the source of a long-standing problem

This Simple Chemistry Fix Could Revolutionize Flow Batteries

A new twist on bromine-based flow batteries could make large-scale energy storage cheaper, safer, and far longer-lasting. Bromine-based flow batteries store and release energy through a chemical reaction involving bromide ions and elemental bromine. This approach offers several advantages, includ

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.

Nigeria Arrests RaccoonO365 Phishing Developer Linked to Microsoft 365 Attacks

Authorities in Nigeria have announced the arrest of three “high-profile internet fraud suspects” who are alleged to have been involved in phishing attacks targeting major corporations, including the main developer behind the RaccoonO365 phishing-as-a-service (PhaaS) scheme.

The Nigeria Police Force National Cybercrime Centre (NPF–NCCC) said investigations conducted in collaboration with Microsoft and the Federal Bureau of Investigation (FBI) led to the identification of Okitipi Samuel, also known as Moses Felix, as the principal suspect and developer of the phishing infrastructure.

“Investigations reveal that he operated a Telegram channel through which phishing links were sold in exchange for cryptocurrency and hosted fraudulent login portals on Cloudflare using stolen or fraudulently obtained email credentials,” the NPF said in a post shared on social media.
