Medical Xpress / Imaging study reveals widespread brain connection loss in schizophrenia

Research involving a Rutgers professor sheds new light on the biological basis of schizophrenia by directly measuring synaptic connections in the human brain using specialized positron emission tomography (PET) imaging.

Phys.org / How tides and river water combine to amplify floods

Ocean tides push upstream along coastal rivers, in some cases reaching hundreds of kilometers (hundreds of miles) inland. These inland stretches are known as tidal rivers, and they're the scene of complex interactions between ...

Phys.org / Hidden muscle machinery reveals 50 new gene subfamilies across vertebrates

Within every muscle of every living species with a backbone, a protein called myosin tugs on a partner protein to generate a muscle contraction. This function, discovered in mammals a century ago, has been presumed by scientists ...

Medical Xpress / Ultrafine air particles may drive 2 million premature deaths each year

Ultrafine particles (UFPs) –smaller than 100 nanometres and invisible to the naked eye—contribute substantially to illness and mortality worldwide. That is the finding of an international study led by researchers at the Max ...

Phys.org / World-first neutron lens brings sharp focus to structures inside materials and objects

Researchers at Paul Scherrer Institute (PSI) have developed the world's first achromatic lens for neutron imaging. The lens overcomes a longstanding obstacle in the field: focusing neutrons of different wavelengths well enough ...

Phys.org / Roman telescope will spot distant black holes that shred stars

How do black holes at the centers of galaxies form and grow over time? To answer this question, scientists need to detect and study supermassive black holes at great distances that existed much earlier in the universe's history. ...

Phys.org / Ancient Roman farm women made wine, oil and profits. Historians dismissed them as 'housekeepers'

Female farm managers are hidden in plain sight in ancient Roman texts, mentioned in laws, literature and grave inscriptions across five centuries. Modern historians have generally assumed they were housekeepers, in charge ...

Phys.org / Physicists confirm 20-year-old theory that could boost quantum technology

Future quantum computing will require correlations between distant modules—a feature known as distributed entanglement. Traditionally, such entanglement has relied on active control and repeated measurements. Now, physicists ...

Science X / Ancient asteroid impact may explain Curiosity's first pure sulfur crystals on Mars

The bright yellow sulfur crystals discovered by NASA's Curiosity rover have puzzled scientists because sulfur on Mars is normally associated with mineral formations, not elemental deposits.

Phys.org / Are we missing the universe's 'noosignatures?'

Astrobiology has long been split into two camps: a search for "biosignatures" and a search for "intelligence." These look for very different things, but they also leave a huge gap in between. It took 3.5 billion years for ...

Phys.org / New atomic trap boosts quantum performance by using surface forces

Researchers at Humboldt-Universität zu Berlin have developed a new method for trapping and controlling atoms near an ultrathin glass fiber. This has significantly improved the atoms' ability to store quantum information—an ...

Phys.org / 'Uncanny valley' effect observed in macaques through 3D animated monkey avatars

A new tool that allows researchers to create realistic full-body animations of monkeys has provided the first evidence that nonhuman primates experience the "uncanny valley" phenomenon for body avatars, according to a study ...
