A NASA study is offering new insight into how the Earths water cycle might be influenced by global change.
Regions like the Persian Gulf in the Middle East, shown here by NASAs Moderate Resolution Imaging Spectroradiometer (MODIS) instrument, may face increasingly severe water shortages as global climate changes. CREDIT: NASA GSFC

In recent years, scientists have warned that the water cycle may be affected by temperature changes, as warmer temperatures can increase the moisture-holding capacity of air.
The global water cycle involves the transfer of water molecules between the Earths land masses, cryosphere, oceans and atmosphere. Its a gigantic system powered by the sun, fueling a continuous exchange of moisture between the oceans, atmosphere and land.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
