New typhoon observation device that does not require a parachute demonstrates high accuracy in field tests
The newly developed dropsonde has fins and a lightweight body that allows it to operate without the use of a parachute, unlike traditional dropsondes. Credit: Reiko Matsushita Japanese researchers have demonstrated the high accuracy of a newly developed typhoon observation device designed to be dropped from an aircraft into the eye of a typhoon. The results are published in the…

Observation of gain-induced group delay between multiphoton pulses generated in spontaneous downconversion sources
Deformation of the shape of a photon pair as the spontaneous parametric downconversion interaction strength increases (from left to right). Credit: Thekkadath et al. Spontaneous parametric downconversion (SPDC) and spontaneous four-wave mixing are powerful nonlinear optical processes that can generate multiphoton light beams with unique quantum properties. These processes can be exploited to create a variety of quantum technologies, such…

Asteroid sample return mission allows researchers to conduct largest geophysical observation campaign of its kind
An animated Osiris-Rex departs from the asteroid Bennu. Credit: NASA The OSIRIS-REx project made history last year as the first U.S. mission to bring back an asteroid sample from space. Along with this, a treasure trove of data has also been created. An international research team led by Sandia National Laboratories and including researchers from Los Alamos National Laboratory published…
