984 Scientists uncover the hidden survival trick that lets cancer bounce back

ScienceDaily

Scientists discovered that certain cancer cells use a low-level activation of a DNA-dismantling enzyme—normally seen in cell death—to survive treatment. Instead of dying, these “persister cells” leverage this sublethal signal to regrow. Because the mechanism is non-genetic, it appears much earlier than typical resistance mutations. Targeting this enzyme could help stop tumors from returning.

Israel Deploys World's First Drone Defense Laser

Israel has operationally deployed Iron Beam, a 100,000-watt laser air-defense system capable of shooting down drones, rockets, and mortars at negligible per-shot cost. According to Tom's Hardware, it marks the first real-world deployment of a high-energy laser as part of a modern, multi-layered missile defense network. From the report: The Iron Beam is a short-range line-of-sight laser interceptor that is extremely cheap to run and, therefore, perfectly suited for intercepting... Read more

Tramadol, a popular opioid often seen as a “safer” painkiller, may not live up to its reputation. A large analysis of clinical trials found that while it does reduce chronic pain, the relief is modest—so small that many patients likely wouldn’t notice much real-world benefit. At the same time, tramadol was linked to a significantly higher risk of serious side effects, especially heart-related problems like chest pain and heart failure,... Read more

Alzheimer’s has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain’s energy supply help drive the disease—and restoring that balance can reverse damage, even in advanced cases. In mouse models, treatment repaired brain pathology, restored cognitive function, and normalized Alzheimer’s biomarkers. The results offer fresh hope that recovery may be possible. Read more

Researchers have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons process incoming information before sending signals onward. This reveals a missing layer of brain communication that has been invisible until now. The discovery could reshape how scientists study learning, memory, and brain disease. Read more

A new eco-friendly technology can capture and destroy PFAS, the dangerous “forever chemicals” found worldwide in water. The material works hundreds to thousands of times faster and more efficiently than current filters, even in river water, tap water, and wastewater. After trapping the chemicals, the system safely breaks them down and refreshes itself for reuse. It’s a rare one-two punch against pollution: fast cleanup and sustainable destruction. Read more

The familiar fight between “mind as software” and “mind as biology” may be a false choice. This work proposes biological computationalism: the idea that brains compute, but not in the abstract, symbol-shuffling way we usually imagine. Instead, computation is inseparable from the brain’s physical structure, energy constraints, and continuous dynamics. That reframes consciousness as something that emerges from a special kind of computing matter, not from running the right program. Read more

Scientists discovered that common food emulsifiers consumed by mother mice altered their offspring’s gut microbiome from the very first weeks of life. These changes interfered with normal immune system training, leading to long-term inflammation. As adults, the offspring were more vulnerable to gut disorders and obesity. The findings suggest that food additives may have hidden, lasting effects beyond those who consume them directly. Read more

Deep ocean hot spots packed with heat are making the strongest hurricanes and typhoons more likely—and more dangerous. These regions, especially near the Philippines and the Caribbean, are expanding as climate change warms ocean waters far below the surface. As a result, storms powerful enough to exceed Category 5 are appearing more often, with over half occurring in just the past decade. Researchers say recognizing a new “Category 6” could... Read more

The Arctic is changing rapidly, and scientists have uncovered a powerful mix of natural and human-driven processes fueling that change. Cracks in sea ice release heat and pollutants that form clouds and speed up melting, while emissions from nearby oil fields alter the chemistry of the air. These interactions trigger feedback loops that let in more sunlight, generate smog, and push warming even further. Together, they paint a troubling picture... Read more

When 3D printed, the alloy forms a tightly packed internal structure that gives it exceptional strength. The material could eventually replace heavier, costlier metals in jet engines, cars, and...
