A recent review summarizes the progress made in graphene-semiconductor hybrid photodetectors over the past decade. It begins by introducing key photodetector performance indicators, providing the basis for an accurate performance ...
The 2020s have already seen many lunar landing attempts, although several of them have crashed or toppled over. With all the excitement surrounding the prospect of humans returning to the moon, both commercial interests and ...
Drought is the most devastating environmental stress that farmers face worldwide. With the added pressures of climate change, drought years have become less predictable, more frequent and more severe.
Researchers from the Cluster of Excellence Collective Behavior have developed a computer vision framework for posture estimation and identity tracking that they can use in indoor environments as well as in the wild. This ...
Mission engineers were confident NASA's OSIRIS-APEX (Origins, Spectral Interpretation, Resource Identification—Apophis Explorer) spacecraft could weather its closest ever pass of the sun on Jan. 2, 2024. Their models had ...
Terahertz waves, known as non-ionizing radiation, can turn into ionization radiation when sufficiently many terahertz photons are focused in space and time. A team led by scientists in Korea and the U.S. has created the world's ...
In 1974 Stephen Hawking famously claimed that black holes should emit particles as well as absorb them. This so-called "Hawking radiation" has not yet been observed, but now a research group from Europe has found that Hawking ...
Sexting—sending sexually suggestive or explicit messages and images—is now a widespread practice, and can be a healthy way to express and explore sexuality. However, there is a need to distinguish between consensual sexting ...
Using the National Astronomical Observatory (OAN) in Mexico, astronomers have observed an open cluster known as NGC 1513. Results of the observations, presented in a paper published May 16 on the pre-print server arXiv, yield ...
UNSW quantum engineers have developed a new amplifier that could help other scientists search for elusive dark matter particles.
