Neutron scattering helps clarify magnetic behavior in altermagnetic material

Scientists at the U.S. Naval Research Laboratory (NRL) have identified the true source of a magnetic effect seen in the material ruthenium dioxide (RuO₂), helping resolve an active debate in the rapidly growing field of altermagnetism. The study is published in the journal ACS Applied Materials & Interfaces.

RuO₂ has drawn global attention as a possible “altermagnetic” material, a newly predicted class of materials that could enable faster, more energy-efficient computing technologies. The excitement has been fueled by theory and early experimental reports suggesting that RuO₂ might host an unusual magnetic state with major implications for spintronics and high-speed electronics.

“Altermagnets are a hot field of research right now,” said Steven Bennett, Ph.D., an NRL materials scientist and co-author of the study. “There’s been a rush to experimentally demonstrate what theorists predicted, because the impact on high-speed, energy-efficient computing could be significant.”

Quantum trembling: Why there are no truly flat molecules

Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a sheet of paper. But quantum physics tells a different story. In reality, nature resists rigidity and forces even the simplest structures into the third dimension.

Researchers led by Professor Reinhard Dörner of the Institute for Nuclear Physics at Goethe University have now determined the precise spatial structure of the “flat” formic acid molecule using an X-ray beam from the PETRA III synchrotron radiation source at the DESY accelerator center in Hamburg. They collaborated with colleagues from the universities of Kassel, Marburg and Nevada, the Fritz Haber Institute, and the Max Planck Institute for Nuclear Physics. The study is published in Physical Review Letters.

To accomplish this, they made use of two effects that occur when X-ray radiation strikes a molecule. First, the radiation ejects several electrons from the molecule (photoelectric effect and Auger effect). As a result, the atoms become so highly charged that the molecule bursts apart in an explosion (Coulomb explosion). The scientists succeeded in measuring these processes sequentially, even though they take place within femtoseconds—millionths of a billionth of a second.

Impact-formed glass provides evidence of cosmic collision in Brazil about 6 million years ago

For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth’s surface. These structures, named geraisites in honor of the Brazilian state of Minas Gerais, where they were first discovered, constitute a new strewn field. This expands the incomplete record of impacts in South America.

The discovery was described in an article published in the journal Geology by a team led by Álvaro Penteado Crósta, a geologist and senior professor at the Institute of Geosciences at the State University of Campinas (IG-UNICAMP). Crósta collaborated with researchers from Brazil, Europe, the Middle East, and Australia.

Until now, only five large tektite fields had been recognized on the planet: in Australasia, Central Europe, the Ivory Coast, North America, and Belize. The Brazilian field now joins this select group.

“Cosmic Volcano” Erupts Again: Black Hole Awakens After 100 Million Years

A restarted black hole in J1007+3540 reveals how episodic jet activity and cluster pressure sculpt giant radio galaxies. Astronomers have captured one of the clearest views yet of a black hole returning to life, in a vast radio galaxy where activity stretches nearly one million light-years across

ClickFix Campaign Abuses Compromised Sites to Deploy MIMICRAT Malware

Cybersecurity researchers have disclosed details of a new ClickFix campaign that abuses compromised legitimate sites to deliver a previously undocumented remote access trojan (RAT) called MIMICRAT (aka AstarionRAT).

“The campaign demonstrates a high level of operational sophistication: compromised sites spanning multiple industries and geographies serve as delivery infrastructure, a multi-stage PowerShell chain performs ETW and AMSI bypass before dropping a Lua-scripted shellcode loader, and the final implant communicates over HTTPS on port 443 using HTTP profiles that resemble legitimate web analytics traffic,” Elastic Security Labs said in a Friday report.

According to the enterprise search and cybersecurity company, MIMICRAT is a custom C++ RAT with support for Windows token impersonation, SOCKS5 tunneling, and a set of 22 commands for comprehensive post-exploitation capabilities. The campaign was discovered earlier this month.

FBI: Over $20 million stolen in surge of ATM malware attacks in 2025

The FBI warned that Americans lost more than $20 million last year amid a massive surge in ATM “jackpotting” attacks, in which criminals use malware to force cash machines to dispense money.

According to a Thursday FBI flash alert, more than 700 ATM jackpotting incidents were reported last year alone in a significant spike compared to the roughly 1,900 total incidents reported across the United States since 2020.

These attacks can be carried out in minutes and target the software layer controlling an ATM’s physical hardware, using malicious tools such as the Ploutus malware. Most often, they go undetected by financial institutions and ATM operators until the cash is already gone.
