133 million-year-old dinosaur brain fossil found in England

Soft tissues such as hearts and muscles are very rarely preserved in the fossil record. For that reason, nearly all study of dinosaur soft tissue has to be reconstructed from fossil bones. However, researchers in the United ...

Mini X-ray source with laser light

Physicists from Ludwig-Maximilians-Universität, the Max Planck Institute of Quantum Optics and the TU München have developed a method using laser-generated X-rays and phase-contrast X-ray tomography to produce three-dimensional ...

Researchers produce first laser ultrasound images of humans

For most people, getting an ultrasound is a relatively easy procedure: As a technician gently presses a probe against a patient's skin, sound waves generated by the probe travel through the skin, bouncing off muscle, fat, ...

Progress Toward Artificial Tissue?

(PhysOrg.com) -- For modern implants and the growth of artificial tissue and organs, it is important to generate materials with characteristics that closely emulate nature.

Dinosaur 'mummies' might not be as unusual as we think

A process of desiccation and deflation explains why dinosaur "mummies" aren't as exceptional as we might expect, according to a study published October 12, 2022 in the open-access journal PLOS ONE by Stephanie Drumheller ...

Game-changing nanodiamond discovery for MRI

A Northwestern University study shows that coupling a magnetic resonance imaging (MRI) contrast agent to a nanodiamond results in dramatically enhanced signal intensity and thus vivid image contrast.

The mechanics of puncture finally explained

The feeling of a needle piercing skin is familiar to most people, especially recently as COVID-19 vaccinations gain momentum. But what exactly happens when a needle punctures skin? The answer is revealed in a new paper published ...
