Printing objects from plastic precisely, quickly, and inexpensively is the goal of many 3D printing processes. However, speed and high resolution remain a technological challenge. A research team from the Karlsruhe Institute of Technology (KIT), Heidelberg University, and the Queensland University of Technology (QUT) has come a long way toward achieving this goal. It developed a laser printing process that can print micrometer-sized parts in the blink of an eye. The international team published the work in Nature Photonics.

Stereolithography 3D printing is currently one of the most popular additive manufacturing processes for plastics, ...

New Tool allows Scientists to Peer inside Neutron Stars

Imagine taking a star twice the mass of the sun and crushing it to the size of Manhattan. The result would be a neutron star—one of the densest objects found anywhere in the universe, exceeding the density of any material found naturally on Earth by a factor of tens of trillions. Neutron stars are extraordinary astrophysical objects in their own right, but their extreme densities might also allow them to function as laboratories for studying fundamental questions of nuclear physics, under conditions that could never be reproduced on Earth.

Because of these exotic conditions, scientists still do not understand what exactly neutron stars themselves are made from, their so-called “equation of state” (EoS)...

Brain Discovery holds key to Boosting Body’s Ability to Fight Alzheimer’s, MS

John Lukens, PhD, is investigating how brain injury disrupts drainage of deleterious waste from the brain and how that may contribute to Alzheimer's disease.
John Lukens, PhD, is leading important research that could transform how we approach Alzheimer’s and other neurological diseases.

UVA Health researchers have discovered a molecule in the brain responsible for orchestrating the immune system’s responses to Alzheimer’s disease and multiple sclerosis (MS), potentially allowing doctors to supercharge the body’s ability to fight those and other devastating neurological diseases.

The molecule the researchers identified, called a kinase, is crucial to both removing plaque buildup associated with Alzheimer’s and preventing the debris buildup that causes MS, the researchers found. It does this, the researchers showed, by directing the activity of brain cleaners called microglia...

Red alert: Massive Stars Sound Warning they are about to go Supernova

This artist’s impression shows the supergiant star Betelgeuse as it was revealed thanks to different state-of-the-art techniques on ESO’s Very Large Telescope (VLT), which allowed two independent teams of astronomers to obtain the sharpest ever views of the supergiant star Betelgeuse. They show that the star has a vast plume of gas almost as large as our Solar System and a gigantic bubble boiling on its surface. These discoveries provide important clues to help explain how these mammoths shed material at such a tremendous rate. Credit: European Southern Observatory/L.

Astronomers from Liverpool John Moores University and the University of Montpellier have devised an ‘early warning’ system to sound the alert when a massive star is about ...
