What you know changes how you see things

Researchers have gained important insight into how the human brain processes an object in the visual system and where in the brain this processing takes place. The study shows people perceive objects differently depending on their prior knowledge and experience with that object.

Old drugs hint at new ways to beat chronic pain

A new study points to possible new treatments for chronic pain with a surprising link to lung cancer. Findings of the research, conducted in laboratory mouse models, open up multiple therapeutic opportunities that could allow the world to improve chronic pain management and eclipse the opioid epidemic.

MAVEN and EMM make first observations of patchy proton aurora at Mars

NASA's MAVEN and the United Arab Emirates' EMM missions have released joint observations of dynamic proton aurora events at Mars. By combining the observations, scientists determined that what they were seeing was essentially a map of where the solar wind was raining down onto the planet, opening new avenues for understanding the Martian atmosphere.

Signs of saturation emerge from particle collisions at RHIC

Nuclear physicists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have new evidence that particles called gluons reach a steady 'saturated' state inside the speeding ions. The evidence is suppression of back-to-back pairs of particles emerging from collisions between protons and heavier ions (the nuclei of atoms), as tracked by RHIC's STAR detector. The STAR...

How the brain processes sensory information from internal organs

Most of us think little of why we feel pleasantly full after eating a big holiday meal, why we start to cough after accidentally inhaling campfire smoke, or why we are hit with sudden nausea after ingesting something toxic. However, such sensations are crucial for survival: they tell us what our bodies need at any given moment so that we can quickly adjust our behavior.

Particles pick pair partners differently in small nuclei

The protons and neutrons that build the nucleus of the atom frequently pair up. Now, a new high-precision experiment has found that these particles may pick different partners depending on how packed the nucleus is. The data also reveal new details about short-distance interactions between protons and neutrons in nuclei and may impact results from experiments seeking to tease out further details...
