Laser light detects tumors

Researchers from Jena have developed a device using laser light to detect tumors, providing real-time information for surgeons. This compact microscope combines three imaging techniques and uses artificial intelligence to analyze tissue samples, promising faster and more reliable results than traditional frozen section diagnostics.

The making of 'warm ice'

Researchers at KRISS successfully created room-temperature ice and controlled its growth behaviors by dynamically compressing water up to pressures above 10,000 atmospheres. This technology can artificially control the size, shape, and growth rate of ice regardless of temperature.

Graphene goes to space!

The Graphene Flagship partners with the European Space Agency and the University of Cambridge to launch a rocket into space, testing the printing of graphene patterns on silicon substrates in zero gravity. The mission aims to validate graphene's self-assembly properties and pave the way for its use in long-term space exploration.

Helping physics teachers who don't know physics

A new study by Ohio State University found that focused physics professional development can improve teachers' understanding of physics concepts and their teaching strategies. As a result, students' understanding of physics improved significantly. The training also increased teacher satisfaction and trust in their abilities, leading to...

Adding clinical variables improves accuracy of lung allocation score

A recent study found that including new clinical variables in the lung allocation score improved its accuracy for identifying the sickest cystic fibrosis patients. The updated scoring system also helped patients with chronic obstructive pulmonary disease (COPD) by re-evaluating their pulmonary function testing.
