Physicist discusses the Higgs boson and whether it might change the fate of the universe

On July 4, 2012, researchers at the Large Hadron Collider (LHC) in Switzerland announced with great fanfare that they had successfully detected the Higgs boson, the manifestation of the mechanism that gives some elementary particles their mass. The finding was a triumph of both the experimental skill required to definitively detect the particle, and the theoretical acumen of those who predicted its existence, recognized by the 2013 Nobel Prize in Physics.

Brown University researchers played key roles in both sides of the accomplishment. Experimentalists including David Cutts, Ulrich Heintz, Greg Landsberg and the late Meenakshi Narain made key contributions to the Compact Muon Solenoid (CMS) experiment at the LHC credited with making the discovery. Years earlier, the late Gerald Guralnik was part of a group that made a theoretical prediction of the particle, which many scientists believe to be the most complete description of the Higgs mechanism.

The Higgs was the final missing piece in the standard model of —the theory that describes the basic building blocks of the universe. But its discovery was by no means a final destination for particle physics. Fundamental questions about the Higgs itself remain unanswered.

“This Is From a Meteorite”: Scientist Stunned by Water Inside 400-Million-Year-Old Plant

The research, led by Zachary Sharp, a professor in UNM’s Department of Earth and Planetary Sciences, was recently published in the Proceedings of the National Academy of Sciences (PNAS). The study centers on horsetails, a family of hollow-stemmed plants that have survived on Earth for more than 400 million years.

The researchers found that water moving through these plants experiences such a powerful natural purification process that its oxygen isotope composition closely matches that of meteorites and other materials from beyond our planet.

“It’s a meter-high cylinder with a million holes in it, equally spaced. It’s an engineering marvel,” Sharp said. “You couldn’t create anything like this in a laboratory.”

The Evolution of SOC Operations: How Continuous Exposure Management Transforms Security Operations

Security Operations Centers (SOC) today are overwhelmed. Analysts handle thousands of alerts every day, spending much time chasing false positives and adjusting detection rules reactively. SOCs often lack the environmental context and relevant threat intelligence needed to quickly verify which alerts are truly malicious. As a result, analysts spend excessive time manually triaging alerts, the majority of which are classified as benign.

Addressing the root cause of these blind spots and alert fatigue isn’t as simple as implementing more accurate tools. Many of these traditional tools are very accurate, but their fatal flaw is a lack of context and a narrow focus — missing the forest for the trees. Meanwhile, sophisticated attackers exploit exposures invisible to traditional reactive tools, often evading detection using widely-available bypass kits.

While all of these tools are effective in their own right, they often fail because of the reality that attackers don’t employ just one attack technique, exploit just one type of exposure or weaponize a single CVE when breaching an environment. Instead, attackers chain together multiple exposures, utilizing known CVEs where helpful, and employing evasion techniques to move laterally across an environment and accomplish their desired goals. Individually, traditional security tools may detect one or more of these exposures or IoCs, but without the context derived from a deeply integrated continuous exposure management program, it can be nearly impossible for security teams to effectively correlate otherwise seemingly disconnected signals.

Fake Solidity VSCode extension on Open VSX backdoors developers

A remote access trojan dubbed SleepyDuck, and disguised as the well-known Solidity extension in the Open VSX open-source registry, uses an Ethereum smart contract to establish a communication channel with the attacker.

Open VSX is a community-driven registry for extensions compatible with VS Code, which are popular with AI-powered integrated development environments (IDEs) like Cursor and Windsurf.

The extension is still present on Open VSX as ‘juan-bianco.solidity-vlang’, albeit with a warning from the platform, and has been downloaded more than 53,000 times.

Microsoft: SesameOp malware abuses OpenAI Assistants API in attacks

Microsoft security researchers have discovered a new backdoor malware that uses the OpenAI Assistants API as a covert command-and-control channel.

The company’s Detection and Response Team (DART) discovered the new malware, named SesameOp, during an investigation into a July 2025 cyberattack, which revealed that the malware allowed attackers to gain persistent access to the compromised environment.

Deploying this malware also enabled the threat actors to remotely manage backdoored devices for several months by leveraging legitimate cloud services, rather than relying on dedicated malicious infrastructure that could alert victims to an attack and be taken down during subsequent incident response.

Small brain region linked to schizophrenia risk through unique gene changes

New research published in the American Journal of Psychiatry provides new molecular insights into the role of the habenula, a pea-sized brain region that helps regulate motivation and mood, in contributing to the risk of schizophrenia. A team of researchers at Lieber Institute for Brain Development and Johns Hopkins found that many schizophrenia-related molecular changes appear to be specific to this region, suggesting the habenula could be a potential target for future treatments.

Schizophrenia is a heritable disorder, and a combination of multiple genetic variants contributes to it. This study sought to understand how molecular changes in the habenula region of the brain contribute to the development of . The authors note that they focused on the habenula because of its “emerging role in and functional influence on neurotransmitter systems impacted in schizophrenia.”

The study team, led by Ege A. Yalcinbas, Ph.D., used cutting-edge molecular techniques to analyze postmortem human brains, resulting in the creation of the first cell-by-cell and within-cell gene expression map of the human habenula (Hb). They then compared from 35 individuals with schizophrenia and 33 nonpsychiatric donors.

Functional ultrasound neuroimaging reveals mesoscopic organization of saccades in the lateral intraparietal area

An amazing paper (link:) where functional ultrasound imaging (fUSI) is used to explore how brain activity in the lateral intraparietal cortex (LIP) can predict visual saccades (eye movements) in two monkeys. An impressive array of computational analyses are used to extract insights from the imaged regions. Indeed, predictive models developed by the authors remained fairly stable over the course of up to 900 days! I happen to know two of the authors (Sumner L Norman and Mikhail Shapiro): congratulations to them and their colleagues on this excellent publication!

Our results demonstrate that PPC contains subregions tuned to different directions. These tuned voxels were predominately within LIP and grouped into contiguous mesoscopic subpopulations. Multiple subpopulations existed within a given coronal plane, i.e., there were multiple preferred directions in each plane. A rough topography exists where anterior LIP had more voxels tuned to contralateral downwards saccades and posterior LIP had more voxels tuned to contralateral upwards saccades. These populations remained stable across more than 100–900 days.

We observed large effect sizes with changes in CBV on the order of 10–30% from baseline activity (Fig. 3). This is much larger than observed with BOLD fMRI where the effect size was ~0.4–2% on similar saccade-based event-related tasks27,32. Our results support a growing evidence base that establishes fUSI as a sensitive neuroimaging technique for detecting mesoscopic functional activity in a diversity of model organisms, including pigeons, rats, mice, nonhuman primates, ferrets, and infant and adult humans23,24,25,33,34,35,36,37,38,39,40.

Several studies have reported a patchiness in direction selectivity with many neighboring neurons tuned to approximately the same direction followed by an abruption to a patch of a different preferred direction13,14,41. These results match very closely with the results observed in this study where we found clusters within LIP tightly tuned to one direction with differently tuned clusters in close proximity within a given plane. These results further emphasize the high spatial resolution of fUSI for functional mapping of neuronal activity. These results also closely match a previous study that used fUSI to identify the tonotopic mapping of the auditory cortex and inferior colliculus in awake ferrets where the authors found a functional resolution of 100 µm for voxel responsiveness and 300 µm for voxel frequency tuning34.
