A team of researchers at the Max Born Institute have managed to fully characterize few-femtosecond-long light pulses tunable in the vacuum ultraviolet. These results unlock the possibility for studying valence electron dynamics of many materials in the VUV.The research is published in the journal Nature Photonics.
An eco-friendly system capable of producing propylene oxide (PO) without external electricity or sunlight has been developed. PO is a vital raw material used in manufacturing household items such as polyurethane for sofas and mattresses, as well as polyester for textiles and water bottles.
A research team led by Professors Ja Hun Kwak and Ji-Wook Jang from the School of Energy and Chemical Engineering at UNIST, in collaboration with Professor Sung June Cho of Chonnam National University, has successfully created a self-driven PO production system utilizing in-situ generated hydrogen peroxide (H₂O₂).
The research is published in Nature Communications.
A research group led by Prof. Li Xiangyang from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has made a new discovery: a single organic molecule can induce the Kondo effect in a magnetic atom, challenging the long-standing belief that this quantum phenomenon requires a vast sea of metallic electrons.
The research results were published in Physical Review Letters.
The Kondo effect is a quantum many-body phenomenon where conduction electrons in a metal collectively screen the magnetic moment of a localized impurity atom. It has been helping to explain strongly correlated electron behavior and inspiring advances in nanoscience, molecular electronics, and quantum information research.
NASA’s Perseverance rover has uncovered powerful new evidence that Mars’ Jezero Crater once hosted multiple rounds of flowing water, each creating conditions that could have supported life.
It’s assessed that the attacks involved sending via WhatsApp malicious images in the form of DNG (Digital Negative) files, with evidence of LANDFALL samples going all the way back to July 23, 2024. This is based on DNG artifacts bearing names like “WhatsApp Image 2025/02/10 at 4.54.17 PM.jpeg” and “IMG-20240723-WA0000.jpg.”
Itay Cohen, senior principal researcher at Palo Alto Networks Unit 42, told The Hacker News that they have not observed any significant functional changes between the samples from July 2024 and February 2025, when the most recent LANDFALL artifact was uploaded to VirusTotal.
LANDFALL, once installed and executed, acts as a comprehensive spy tool, capable of harvesting sensitive data, including microphone recording, location, photos, contacts, SMS, files, and call logs.
A threat actor exploited a zero-day vulnerability in Samsung’s Android image processing library to deploy a previously unknown spyware called ‘LandFall’ using malicious images sent over WhatsApp.
The security issue was patched this year in April, but researchers found evidence that the LandFall operation was active since at least July 2024, and targeted select Samsung Galaxy users in the Middle East.
Identified as CVE-2025–21042, the zero-day is an out-of-bounds write in libimagecodec.quram.so and has a critical severity rating. A remote attacker successfully exploiting it can execute arbitrary code on a target device.
