While croplands may provide more food than forests, they don’t offer much relief from hot tropical climes, a new study finds.
A study of Santa Cruz, Bolivia, which used NASA satellites and computer models, reports that cutting down tropical forests and converting grasslands to crops may inadvertently warm those local areas. According to the research, forest canopies create wind turbulence that cools the air, and native grasslands are better adapted to the tropics than crops, in ways that also have a cooling effect.
Lahouari Bounoua, a researcher at the University of Maryland (UMD), College Park, Md., and NASA’s Goddard Space Flight Center (GSFC), Greenbelt, Md., used a computer model to show that temperatures in January may have warmed on average by about 1 degree Fahrenheit in the last 25 years, solely because native forests and grasslands in Santa Cruz were replaced with crops. Co-authors in this interdisciplinary study of land cover and climate changes included University of Maryland researcher, Ruth DeFries, NASA GSFC/UMD scientist Marc Imhoff and NASA GSFC researcher Marc Steininger.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
