Distorted honeycomb magnet edges closer to a quantum spin liquid

Neutron scattering and simulations reveal why a promising Kitaev candidate freezes into order instead of forming a quantum spin liquid.

Most magnets are predictable. Cool them down, and their tiny magnetic moments snap into place like disciplined soldiers. However, physicists have long suspected that, under the right conditions, magnetism might refuse to settle even in extreme cold.

This restless state, known as a quantum spin liquid, could unlock new kinds of particles and serve as a foundation for quantum technologies that are far more stable than today’s fragile systems.

At Oak Ridge National Laboratory (ORNL), researchers have now created and closely examined a new magnetic material that brings this strange possibility a little closer to reality, even if it doesn’t quite cross the finish line yet.

Light-activated tissue adhesive patch offers rapid, watertight neurosurgical sealing

Durotomy is a common neurosurgical complication involving a tear in the dura mater, the protective membrane surrounding the brain and spinal cord. Damage can cause cerebrospinal fluid (CSF) leakage, leading to delayed healing, headaches, and infection, making a reliable watertight dural closure essential.

Tissue adhesives are increasingly being explored as alternatives to suturing for dural closure because they offer simpler and faster application. However, many existing glue-based sealants suffer from excessive swelling, leading to mass effect and unwanted tissue adhesion, which can lead to postoperative complications.

To address these limitations, researchers have investigated Janus tissue patches, which feature two distinct surfaces—one that adheres strongly to tissue and another that prevents unwanted adhesion. Unfortunately, most existing Janus patches rely on multiple materials and complex, multi-step fabrication processes, limiting their practical use.

Scientist Say Aging Can Be Stopped! — Jose Cordeiro

We sit down with José Cordeiro, author of The Death of Death, to uncover the timeline scientists believe could end aging — and even achieve immortality. From the promise of longevity escape velocity by 2030 to Ray Kurzweil’s bold prediction of immortality by 2045, José reveals the breakthroughs, roadblocks, and revolutionary ideas shaping the future of human life.

The regeneration model of aging and its practical implications

Aging is a primary risk factor for multi-morbidity and declining quality of life. The geroscience hypothesis states that targeting biological aging mechanisms may prevent or delay morbidity; however, translating theory into practice remains challenging. Unknown long-term risks and a lack of well-validated, responsive, and practical surrogate endpoints especially hinder the field’s preventive aspirations. This review addresses these obstacles by introducing the regeneration model of aging—a novel framework that integrates biological aging processes and distills the complexity of aging into a series of fundamental steps. The model provides insights into potential trade-offs of anti-aging interventions and can guide strategies to slow aging across diverse populations.

Recent progress in cryoablation cancer therapy and nanoparticles mediated cryoablation

Hematopoietic aging extends far beyond the confines of the bone marrow, functioning as a central regulator of systemic decline through its influence on inflammation, immune dysregulation, and inter-organ communication. Moreover, reciprocal signaling from peripheral organs, such as the brain and gut, further shapes hematopoietic aging, highlighting the bidirectional nature of these interactions (Figure 3).

Scientists Develop IV Therapy That Repairs the Brain After Stroke

New nanomaterial passes the blood-brain barrier to reduce damaging inflammation after the most common form of stroke. When someone experiences a stroke, doctors must quickly restore blood flow to the brain to prevent death. However, this sudden return of circulation can also set off a harmful casca

Engineers just created a “phonon laser” that could shrink your next smartphone

Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can produce ultra-fast surface waves that already play a hidden role in smartphones, GPS systems, and wireless tech. Unlike today’s bulky setups, this single-chip device could deliver far higher performance using less power, opening the door to smaller, faster, and more efficient phones and wireless devices.

Artemis II astronauts will take bone marrow ‘avatars’ to the Moon, to see how damaging spaceflight really is

The agency also says studies show microgravity affects the development of bone marrow cells.

And while astronauts on the Space Station are shielded from much of the cosmic and solar radiation by the Earth’s magnetosphere, the Artemis II crew will fly beyond our planet’s protective layer.

Artemis II astronauts donate platelets that contain cells with a portion of stem and progenitor cells from their bone marrow.

This Quantum Discovery May Bypass the ‘No-Cloning Theorem,’ Opening the Door to Quantum Cloud Storage

Scientists have demonstrated a new method that could allow quantum information to be safely backed up, overcoming one of the longest-standing limitations in quantum computing without violating the fundamental laws that govern quantum systems.

The research describes a way to encode the information contained in a qubit across multiple entangled systems, allowing the original quantum state to be recovered later without directly copying it.

Buried under 2 km of Antarctic ice, scientists discover a lost world 34 million years old

The drill site looked like a tiny scar on an endless white sheet. Floodlights threw sharp cones of yellow on the snow while the rest of Antarctica stayed blue and silent, as if the continent itself was holding its breath. The wind slapped the tents, the generators coughed, and a handful of scientists stood around
