Smart farming: AI technologies for sustainable agriculture

Changing climatic conditions, the shortage of skilled workers, the use of pesticides—a wide range of factors have an impact on the quality and flow of agricultural processes. Researchers at the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI are aiming to make this more efficient and sustainable by means of cloud and AI technologies. As part of the "NaLamKI" project,...

From medical applications to sporting goods: Biocompatible and sustainable plastics

Numerous plastic products are made of polyurethanes. Fraunhofer researchers have developed a manufacturing method for polyurethanes that avoids use of toxic isocyanates while making use of carbon dioxide as a starting material. Polyurethanes of a reproducible standard are being developed in collaboration with partners from industry. The research results can be seen from November 15 to 18 at MEDICA...

Video: Change in the Arctic

Satellites play a vital role in monitoring the rapid changes taking place in the Arctic. Tracking ice lost from the world's glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate.

New methods for detecting single molecules

Resistance to antibiotics is on the rise worldwide. Researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM alongside the Ludwig Maximilian University of Munich have developed a process for rapidly detecting multidrug-resistant pathogens. The unique feature: Even one single molecule of DNA is sufficient for pathogen detection. In future, the platform could be introduced as...

A cosmic whodunit: ALMA study confirms what's robbing galaxies of their star-forming gas

Astronomers examining the nearby universe with the help of the Atacama Large Millimeter/submillimeter Array (ALMA) have just completed the largest high-resolution survey of star-forming fuel ever conducted in galaxy clusters. But more importantly, they're tackling a long-standing mystery in astrophysics: What's killing galaxies? The research, which provides the clearest evidence to date that...

Researchers explore the extremely metal-poor galaxy DDO 68

By performing hydrodynamical simulations, astronomers have investigated an extremely metal-poor galaxy known as DDO 68. Results of the study, presented in a paper published October 25 on the arXiv pre-print server, shed more light on the origin and nature of this peculiar galaxy.

Using optical microscopy to take a look beneath the skin of 'surfactant onions'

Surfactant onions form when layers of surfactant molecules organize around each other into a sphere. They are easily pictured by thinking of their vegetable namesake. Until now it has not been clear whether surfactant onions are perfect layered structures or whether they contain defects. Researchers from the University of Tokyo Institute of Industrial Science have used microscopy to get a better...

Making space travel inclusive for all

In a weightless, microgravity environment like space, what do ability and disability look like? How can someone with partial sight or impaired mobility navigate in a confined space like the space station? As scientists and innovators continue to push the boundaries of spaceflight and the possibility of human life on other planets, how can we build space infrastructure that is inclusive of all...

Hubble remains in safe mode, NASA team investigating

NASA is continuing to investigate why the instruments in the Hubble Space Telescope recently went into safe mode configuration, suspending science operations. The instruments are healthy and will remain in safe mode while the mission team continues its investigation.

ESA and NASA release the first globally harmonized assessment of above-ground biomass

Today, ESA and NASA have publicly released the first globally harmonized assessment of above ground biomass—information that is vital for managing global climate change. The Multi-Mission Algorithm and Analysis Platform (MAAP) provides seamless access to above ground biomass information from both NASA and ESA Earth observation data. The revolutionary open-science tool is now fully operational...

The Cow That Could Feed the Planet

The cows in Farmer John’s pasture lead an idyllic life. They roam through tree-shaded meadows, tearing up mouthfuls of clover while nursing their calves in tranquility. Tawny brown, compact and muscular, they are Limousins, a breed known for the quality of its meat and much sought-after by the high-end restaurants and butchers in the nearby…
