A water-sensing satellite orbits more than 400 miles above Earth. An instrument-packed airplane circles 25,000 feet above three U.S. states and Brazil. Scientists, college students and other volunteers troop into the countryside, armed with sensors and notepads. It’s all about "getting the dirt." In this case, collecting detailed information about the soil.

The objectives are two-fold — validating soil moisture data gleaned from satellites and working to find the optimum instrument for conducting soil moisture remote sensing. By learning how to better gauge the amount of moisture in the soil, scientists are pursuing the long-range goal of eventually helping to improve the accuracy of weather forecasts and better estimate crop yields through remote-sensing methods.
Led by Dr. Thomas Jackson of the U.S. Department of Agriculture (USDA), Soil Moisture Experiments in 2003, or SMEX03, is a collaboration between NASA, the USDA’s Agricultural Research Service, the Brazilian Agricultural Research Corporation, several academic institutions across the United States, and the Center for Hydrology, Soil Climatology, and Remote Sensing (HSCaRS) of Alabama A&M University in Huntsville — a NASA-sponsored Minority University Research Center that promotes minority and women student involvement in Earth science research.

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...
Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.
A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
By studying the chemical elements on Mars today -- including carbon and oxygen -- scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life.
Weaving this story, element by element, from roughly 140 million miles (225 million kilometers) away is a painstaking process. But scientists aren't the type...
Study co-led by Berkeley Lab reveals how wavelike plasmons could power up a new class of sensing and photochemical technologies at the nanoscale
Wavelike, collective oscillations of electrons known as "plasmons" are very important for determining the optical and electronic properties of metals.
