Roughly 90 million years ago, climatic conditions in Antarctica were suitable for resin-producing trees. A team of researchers led by the Alfred Wegener Institute and the TU Bergakademie Freiberg have just released a paper in the journal Antarctic Science, in which they describe the southernmost discovery of amber in the world.

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis that invisible dark matter helped the earliest stars and galaxies clump together.

An international research team has for the first time designed realistic photonic time crystals –– exotic materials that exponentially amplify light. The breakthrough opens up exciting possibilities across fields such as communication, imaging and sensing by laying the foundations for faster and more compact lasers, sensors and other optical devices.

University of B.C. researchers have developed a groundbreaking coating that could make medical devices safer for millions of patients, reducing the risks associated with blood clots and dangerous bleeding. The new material is designed to mimic the natural behavior of blood vessels so that catheters, stents, blood-oxygenation machines and dialysis machines won't trigger clotting by activating certain proteins in the blood. 

A research team from the University of Basel has succeeded in synthesizing simple, environmentally sensitive cells complete with artificial organelles. For the first time, the researchers have also been able to emulate natural cell-cell communication using these protocells – based on the model of photoreceptors in the eye. This opens up new possibilities for basic research and applications in medicine.

This work introduces a novel tandem hydrothermal-calcination synthesis strategy to construct a p-n heterojunction between ultrasmall Te nanoparticles and CN nanosheets. The optimized Te/CN-NH₃ catalyst exhibits outstanding photocatalytic CO₂ reduction activity and stability, achieving nearly 100% CO selectivity and a yield of 92.0 μmol g^-1 h^-1—four times higher than that of pure CN.
