Using the first science image released by the James Webb Space Telescope (JWST) this month, an international team of scientists with significant contribution from the Technical University of Munich (TUM) has built an improved model for the mass distribution of the galaxy cluster SMACS J0723.3−7327. Acting as a so-called gravitational lens, the foreground galaxy cluster produces both multiple images of background galaxies and magnifies these images...

The damaging effects of daily, lifelong exposure to the blue light emanating from phones, computers and household fixtures worsen as a person ages, new research by Oregon State University suggests.

The study, published today in Nature Partner Journals Aging, involved Drosophila melanogaster, the common fruit fly, an important model organism because of the cellular and developmental mechanisms it shares with other animals and humans.

Jaga Giebultowicz, a researcher in the OSU College of Science who studies biological clocks, led a collaboration that examined the survival rate of flies kept in darkness and then moved at progressively older ages to an environment of constant blue light from light-emitting diodes, or LEDs.

The darkness-to-light transitions occurred at the ages of...

An international team has successfully implemented an advanced form of quantum cryptography for the first time. Moreover, encryption is independent of the quantum device used and therefore even more secure against hacking attempts.

The Internet is teeming with highly sensitive information. Sophisticated encryption techniques generally ensure that such content cannot be intercepted and read. But in the future high-performance quantum computers could crack these keys in a matter of seconds. It is just as well, then, that quantum mechanical techniques not only enable new, much aster algorithms, but also exceedingly effective cryptography.

Quantum key distribution (QKD) is secure against attacks on the communication channel, but not against attacks on or manipulations of the devices...

Cheap and quick to produce, these digitally manufactured plasma sensors could help scientists predict the weather or study climate change.

MIT scientists have created the first completely digitally manufactured plasma sensors for orbiting spacecraft...
