Phys.org / Quantum gravity research links continuous parameters to local operators within the theory itself

A researcher at Kyushu University and his collaborators have shown that continuous parameters in quantum gravity may not be freely adjustable "dials" from outside the theory, but rather arise from operators within the theory ...

Phys.org / Horizon edge states gain finite description in string theory calculation

Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are ...

Phys.org / How long can plants survive on Earth? New model suggests up to 2 billion more years

Vegetarians need not worry yet—plants will be on Earth for a long time to come. But not forever. The sun will ultimately determine the long-term existence of life on Earth. Its total energy output, called luminosity, has ...

Phys.org / Antarctica is offering 30 to 50 years' worth of warning on sea level rise, models suggest

Scientists predict that the next three to five decades provide a critical window to anticipate and plan for Antarctic ice loss and its contribution to sea level rise. Research published in Nature, led by Monash University ...

Phys.org / Bullet Cluster observations reopen dark matter debate with MOND-compatible explanation

The Bullet Cluster has so far been considered evidence of the existence of dark matter. An international team of researchers has now analyzed new data and current images from the James Webb Space Telescope (JWST). According ...

Tech Xplore / Brain-inspired AI architecture could compute faster while using far less power

Spiking neural networks (SNNs) are artificial intelligence (AI) models inspired by how biological neurons communicate with each other. While biological neurons exchange information in the form of electrical impulses, SNNs ...

Phys.org / Building more apartments won't ease housing crisis

Building more apartments will not solve Australia's housing affordability crisis unless policymakers address rising house prices and investor activity, new research shows. Australia's housing affordability crisis is being ...

Medical Xpress / Two patients with severe autoimmune disease remain relapse-free for over 15 years after stem cell transplant

Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune condition in which the body's own defenses turn against the optic nerves and spinal cord. This confusion leads to inflammation that can rob people of their ...

Medical Xpress / Hope for spinal injuries as pigs walk again after experimental gel treatment for severed spinal cords

In humans and other mammals, spinal cord injuries can be devastating, leading to permanent loss of movement, sensation and bladder control. When severed axons (the long fibers that carry messages between nerve cells) cannot ...

Phys.org / Human sacrifice in Inca Empire may have been driven by political motives, not religion

Three decades ago, researchers working atop the Llullaillaco volcano, located on the border between Argentina and Chile, discovered exceptionally well-preserved remains. The find included the mummified bodies of three children ...

Phys.org / 'Timescapes' may help explain how animal species perceive events so differently in time

There is evidence that nonhuman animals perceive the world, and how it unfolds in time, differently from humans and from each other. For example, certain beetles can see flickering in lights up to around 500 Hz, while in ...
