Sensitive measurements uncover dual superconducting states in atom-thin NbSe₂ and TaS₂

A new study reveals that two widely studied ultrathin superconducting materials are more sophisticated than they appear. Although they seem to behave like simple superconductors with a single energy gap, they actually contain two strongly interacting superconducting states that work together and disguise themselves as one. This finding resolves a long-standing mystery about how these materials behave, providing new insight into superconductivity that could help scientists design better superconducting materials for future technologies such as quantum computers, ultra-efficient electronics and advanced sensors.

Sometimes, the biggest scientific discoveries come from looking more closely at something we thought we already understood. For decades, physicists have studied a remarkable class of materials called superconductors—materials that can carry electricity with zero energy loss. These materials could one day help power ultra-efficient electronics, quantum computers and advanced medical technologies.

One of the most widely studied superconductors, niobium diselenide (NbSe₂), seemed straightforward when peeled down to just a few atomic layers. Experiments suggested it behaved like a superconductor with a single energy gap—a fundamental fingerprint that describes how electrons order in pairs to flow without resistance.

Cursor Flaw Lets Malicious Cloned Repositories Trigger Windows Code Execution

Whatever that binary does, it does as you, with your source, your SSH keys and your cloud tokens. Cursor keeps re-running it for as long as the project stays open.

No prompt injection, no agent, no model in the loop, and no prior access to the machine: opening the folder is the entire exploit, and the result is arbitrary code execution as the logged-in user.

AI security firm Mindgard reported the flaw to Cursor on December 15, 2025 and published full technical details on Tuesday, seven months later. There is still no patch, and Cursor has published no advisory for the issue.

Google Gemini CLI abused as a hacking agent, malware botnet operator

A Russian-speaking threat actor known as “bandcampro” used Google’s open-source Gemini CLI AI tool as a hacking agent and to operate a small-scale botnet.

The AI agent responded to the attacker’s prompts, troubleshooting problems on the fly and even proposing operational improvements at least 59 times.

In more than 200 sessions between May 19 and April 21, the threat actor worked with the AI tool to deploy and operate an infrastructure that controlled eight systems in a dental clinic and to get access to the OpenDental database.

New tool makes immune therapy more effective in prostate cancer

Prostate cancer is often resistant to immunotherapy, which harnesses a person’s immune system to recognize and destroy tumors. But a new technology that targets RNA in cancer cells gave immunotherapy new life, improving its ability to unleash cancer-killing cells in laboratory studies.

Most prostate tumors are dubbed “immune cold” because they don’t attract T cells (a type of immune cell) to the tumor. Using a CRISPR-based tool, researchers altered RNA to make the cancer cells more like magnets for T cells, allowing them to draw in and use the antitumor cells to destroy the cancer.

Published in Nature Biomedical Engineering, the study found the technology made prostate tumors more responsive to immune checkpoint therapy in mice, increasing the number of immune cells that infiltrated the tumor and subsequently destroyed cancerous cells.

A Framework for Frontier AI and the Dawning of a New Age

Assorted web links to important articles.

This is a pivotal moment in human history. Artificial General Intelligence (AGI), a system that exhibits all the cognitive capabilities the brain has, is probably only a few short years away. When we look back on this time in the decades to come, I think we will realise we were standing in the foothills of the singularity — nothing less than the dawning of a new age for humanity.

I’ve spent my whole life working on AGI because I’ve always had a deep conviction that, if built and deployed responsibly, it would prove to be one of the most beneficial and transformative technologies ever invented. AGI cannot be compared to standard technological breakthroughs, not even ones as consequential as the internet or mobile — it is much more akin to the discovery of electricity or fire. If you stop to think about it, we’ve essentially found a way to make sand think. It’s miraculous.

The magnitude of this technology’s impact will be unprecedented, perhaps 10x of the Industrial Revolution at 10x the speed. It will help us solve some of the biggest problems society faces from accelerating drug discovery to developing new clean energy sources to creating novel advanced materials. We could even reach a point where resources are no longer the limiting factor for human progress, leading to an amazing new era of abundance.

Subcellular localization as a driver of protein function

Proteins can localize to multiple cellular compartments and some exhibit distinct functions depending on their location. This Review discusses the mechanisms of protein localization, the control of specialized protein functions through subcellular localization, and how mislocalization is involved in cancer, neurodegeneration and autoimmunity.

Unlocking the Antimicrobial Potential of Mushrooms: A Natural Defence Against Pathogens

A little know fact is that mushrooms are a natural food to prevent disease especially in superbugs that keep getting stronger. This simple fact allows for better cheaper forms of natural defenses against viruses that can be almost out of control in some areas. Also they are cheaper to make than even antiviral medicines.

Mushrooms have long been celebrated for their culinary and medicinal properties. Species such as Ganoderma lucidum (Reishi) and Lentinula edodes (Shiitake) have been extensively used in traditional medicine for their immune-boosting and anti-inflammatory properties. Despite their well-documented nutritional and health benefits, the antimicrobial potential of mushrooms remains underexplored. Recent studies have shown that compounds like polysaccharides and phenolics found in mushrooms can effectively inhibit the growth of drug-resistant pathogens, including Methicillin-resistant Staphylococcus aureus (MRSA) and Candida albicans. For instance, Lentinula edodes extracts have demonstrated antibacterial activity against E. coli and antifungal properties against Candida species, highlighting their potential as a source of novel antimicrobial agents.

A Last-Resort Antibiotic Is Losing The Battle Against a Dangerous Hospital Bug

The combination drug ceftazidime-avibactam (CZA) is a last line of defense against the common Pseudomonas aeruginosa hospital bug: It’s the drug that gets called in when nothing else works, but there’s now evidence that it may not keep working for long.

Based on an analysis of two critically ill patients with P. aeruginosa infections, the bacteria are developin g genetic mutations that change the enzymes they produce – and can ward off an attack from CZA.

Researchers led by a team from Tongji University in China have now published a new paper in Microbiology Spectrum detailing the mutations and what it might mean for fighting P. aeruginosa in the future.
