Gaining insight could help understand the timing and process of life’s emergence. A research team led by a Rutgers-New Brunswick scientist has found that water arrived on Earth later in its formation than previously believed. This discovery has important implications for understanding when life first emerged on the planet.

Microsoft patches 63 flaws, including two exploited Windows vulnerabilities (CVE-2025–21391, CVE-2025–21418). CISA requires fixes by March 4.
Euclid, a space telescope on a mission to uncover the secrets of dark matter and dark energy, has already made a stunning discovery: a perfectly formed Einstein ring hidden in a well-known galaxy.
This rare phenomenon, predicted by Einstein’s theory of relativity, reveals the power of gravitational lensing, allowing scientists to glimpse far-off galaxies otherwise invisible. The find is a testament to Euclid’s groundbreaking capabilities, suggesting a future filled with even more cosmic surprises.

A study has found that the cortex acts like a ‘memory machine’, encoding new experiences and predicting the near future, helping to differentiate between novel and old information.
Terahertz radiation (THz), electromagnetic radiation with frequencies ranging from 0.1 and 10 THz, is central to the functioning of various technologies, including imaging, sensing and spectroscopy tools. While THz radiation waves have been manipulated in different ways over the past decades, controlling their direction in air has so far remained a challenge.
Researchers at Ecole Polytechnique (CNRS) at Institut Polytechnique de Paris recently demonstrated the steering of laser-produced THz radiation in air, using a recently introduced technique dubbed “flying focus.” Their paper, published in Physical Review Letters, could open new possibilities for the manipulation of THz electromagnetic waves, which could in turn be leveraged to develop new technologies.
“My group has been working on the generation of THz radiation by laser-induced filaments in air for almost 20 years,” Aurélien Houard, senior author of the paper, told Phys.org. “A major advantage of these filaments is that they can be generated at a large distance from the laser in the atmosphere. However, the THz emission remained confined close to the laser axis, which is not convenient for remote detection.”
Carnegie Mellon University’s Professor Curtis Meyer and his research colleagues explore an uncharted world inside protons and neutrons. For the first time, researchers have provided measurements describing a maximum boundary for a subatomic particle known as a hybrid meson in a journal paper published in Physical Review Letters. The measurements show scientists a path forward in a search for these elusive particles that provide a new look at the force that holds all matter together.
“The stage is set for future discoveries,” said Meyer, senior associate dean for CMU’s Mellon College of Science and the Otto Stern Professor of Physics. “We’re at an exciting phase where we’re able to analyze a great deal of data. This paper is the first to address one of the experiment’s foundational questions.”
Applying a symmetry property of the strong force, the team set the upper limit on the photoproduction cross sections of a hybrid meson known as the spin-exotic π1 (1600).
The commonplace phenomenon of liquid drops falling from a surface is—perhaps surprisingly—not yet fully understood by scientists. Understanding the complex interactions between the forces involved here would be helpful in industry, where structured packings in cooling towers must be designed to encourage droplet formation in fluid flow but coatings mixed to maintain a pristine, smooth surface.
Furthermore, the design of meshes used to harvest clean water from fog or dew, where this is limited, relies on an understanding of how the water condenses on the fibers and drops into collection tanks.
Atefeh Pour Karimi, a Ph.D. student at the Institute of Heat and Mass Transfer, Aachen University, Germany, and her supervisors and collaborators have analyzed the dynamics of this type of flow in detail and published their findings in The European Physical Journal Special Topics.
A large-scale brute force password attack using almost 2.8 million IP addresses is underway, attempting to guess the credentials for a wide range of networking devices, including those from Palo Alto Networks, Ivanti, and SonicWall.
A brute force attack is when threat actors attempt to repeatedly log into an account or device using many usernames and passwords until the correct combination is found. Once they have access to the correct credentials, the threat actors can then use them to hijack a device or gain access to a network.
According to the threat monitoring platform The Shadowserver Foundation, a brute force attack has been ongoing since last month, employing almost 2.8 million source IP addresses daily to perform these attacks.
