Instantly turning a material from opaque to transparent, or from a conductor to an insulator, is no longer the stuff of science fiction. For several years now, scientists have been using lasers to control the properties of matter at extremely fast rates: during one optical cycle of a light wave. But because these changes occur on the timescale of attoseconds—one-billionth of one-billionth of a second—figuring out how they unfold is extremely difficult.

In a new study published in Nature Photonics, Prof. Nirit Dudovich’s team from the Weizmann Institute of Science presents an innovative method of tracking these rapid material changes. This advance in attosecond science, the study of the fastest phenomena in nature, could have a wide variety of future applications, paving the way for ultrafast communications and computing.

If you have ever seen a rainbow, you’ve seen a practical demonstration of how light slows down and is refracted when it passes through matter, in this case, raindrops. Sunlight is composed of a broad spectrum of colors, each of which experiences a different delay as it passes through the droplets. These differences cause the colors to become separated, producing a radiant rainbow.

Using the Multi-frequency High Field Electron Spin Resonance Spectrometer at the Steady-State High Magnetic Field Facility (SHMFF), researchers observed the first-ever Bose–Einstein condensation (BEC) of a two-magnon bound state in a magnetic material. The facility is in the Hefei Institutes of Physical Science of the Chinese Academy of Sciences and includes a research team from Southern University of Science and Technology, Zhejiang University, Renmin University of China, and the Australian Nuclear Science and Technology Organization.

This discovery was published in Nature Materials.

BEC is a fascinating quantum phenomenon where particles, typically bosons, condense into a single collective state at ultra-low temperatures. While this effect has been seen in cold atoms, it had never been observed in a magnetic system until now.

Researchers from Tsinghua University, the Beijing Institute of Technology, the University of Wollongong (Australia), and the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, have achieved an ultrahigh electrostrain of 1.9% in (K, Na)NbO3 (KNN) lead-free piezoelectric ceramics.

The breakthrough, facilitated by the (ESR) spectrometer at the Steady High Magnetic Field Experimental Facility (SHMFF), marks a significant advancement in piezoelectric material performance.

The findings are published in Nature Materials.

Researchers at the University of Adelaide have performed the first imaging of embryos using cameras designed for quantum measurements.

The University’s Center of Light for Life academics investigated how to best use ultrasensitive technology, including the latest generation of cameras that can count individual packets of light energy at each pixel, for life sciences.

Center director Professor Kishan Dholakia said the sensitive detection of these packets of light energy, termed photons, is vitally important for capturing in their natural state—allowing researchers to illuminate with gentle doses of light.

For decades, scientists believed that lead-208, a “doubly magic” and highly stable atomic nucleus, was perfectly spherical. However, groundbreaking new research has shattered this assumption, revealing that its nucleus is actually elongated, much like a rugby ball.

By using an advanced gamma-ray spectrometer and high-speed particle collisions, researchers uncovered unexpected quantum behavior that contradicts long-standing nuclear theory. This revelation forces physicists to rethink fundamental principles of nuclear structure, potentially reshaping our understanding of heavy elements and their formation in the universe.

A major breakthrough in organic semiconductors.

Semiconductors are materials with electrical conductivity that falls between conductors and insulators, making them essential for modern electronics. They are typically crystalline solids, the most common of which is silicon, used extensively in the production of electronic components such as transistors and diodes. Semiconductors are unique because their conductivity can be altered and controlled through doping—adding impurities to the material to change its electrical properties. This property allows them to serve as the foundation for integrated circuits and microchips, powering everything from computers and smartphones to advanced medical devices and renewable energy technologies. The behavior of semiconductors is also crucial in the development of various electronic, photonic, and quantum devices.

Threat intelligence company GreyNoise warns that a critical PHP remote code execution vulnerability that impacts Windows systems is now under mass exploitation.

Tracked as CVE-2024–4577, this PHP-CGI argument injection flaw was patched in June 2024 and affects Windows PHP installations with PHP running in CGI mode. Successful exploitation enables unauthenticated attackers to execute arbitrary code and leads to complete system compromise following successful exploitation.

A day after PHP maintainers released CVE-2024–4577 patches on June 7, 2024, WatchTowr Labs released proof-of-concept (PoC) exploit code, and the Shadowserver Foundation reported observing exploitation attempts.

A new ransomware operator named ‘Mora_001’ is exploiting two Fortinet vulnerabilities to gain unauthorized access to firewall appliances and deploy a custom ransomware strain dubbed SuperBlack.

The two vulnerabilities, both authentication bypasses, are CVE-2024–55591 and CVE-2025–24472, which Fortinet disclosed in January and February, respectively.

When Fortinet first disclosed CVE-2024–55591 on January 14, they confirmed it had been exploited as a zero-day, with Arctic Wolf stating it had been used in attacks since November 2024 to breach FortiGate firewalls.
