NASA hurricane researchers are deploying to Costa Rica next month to investigate the birthplace of eastern Pacific tropical cyclones. They will be searching for clues that could lead to a greater understanding and better predictability of one of the world’s most significant weather events – the hurricane.
As scientists and coastal residents brace for another potentially challenging hurricane season, NASA is launching the Tropical Cloud Systems and Processes (TCSP) mission. TCSP is a month-long research effort primarily intended to document "cyclogenesis," the birth of tropical storms, hurricanes and related phenomena.
Researchers will monitor oceanic thunderstorms to study why some systems develop into tropical cyclones and some do not. Researchers feel the data is vital to understanding how such weather systems evolve and travel. The data also could support development of a more accurate and timely warning system to help safeguard property and lives. A team of atmospheric scientists, engineers and aircraft personnel will take up residence in San Jose, Costa Rica during July. The NASA team will work with the National Oceanic and Atmospheric Administration (NOAA) and Costa Rican Centro Nacional de Alta Tecnologia (CENAT). The team will conduct ground-based and airborne studies to measure the buildup and behavior of tropical storm systems on Costa Ricas east and west coasts.

Climate change: In their old age, trees still accumulate large quantities of carbon

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
