Scientist Heinz Frei has spent decades working toward building an artificial version of one of nature's most elegant and effective machines: the leaf.
The heliosphere is a vast region, extending more than twice as far as Pluto. It casts a magnetic “force field” around all the planets, deflecting charged particles that would otherwise muscle into the solar system and even tear through DNA. However, the heliosphere, despite its name, is not actually a sphere. Space physicists have long compared its shape to a comet, with a round “nose” on one side and a long tail extending in the opposite direction.
The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil between neighbouring coastal states, according to new research from McGill University in collaboration with University of Colorado Boulder, Columbia University, and Arizona State University.
ITHACA, N.Y. - New Cornell University research is producing a more accurate historical timeline for the occupation of Native American sites in upstate New York, based on radiocarbon dating of organic materials and statistical modeling.
The results from the study of a dozen sites in the Mohawk Valley were recently published in the online journal PLoS ONE by Sturt Manning, professor of classical archaeology; and John Hart, curator in the research and collections division of the New York State Museum in Albany.
Researchers are using a kind of machine learning known as sentiment analysis to assess the successes and failures of wildlife conservation over time. In their study, appearing March 19 in Patterns--a new open access data science journal from Cell Press--the researchers assessed the abstracts of more than 4,000 studies of species reintroduction across four decades and found that, generally speaking, we're getting better and better at reintroducing species to the wild.
PULLMAN, Wash. - When teachers use a funny joke, a cat video or even background music in their lessons, it can keep students from understanding the main content.
A system that can concurrently transmit light and energy to underwater energy devices is under development at KAUST. Self-powered internet of underwater things (IoUT) that harvest energy and decode information transferred by light beams can enhance sensing and communication in the seas and oceans. KAUST researchers are now solving some of the many challenges to this technology being employed in such harsh and dynamic environments1.
Clay pots? Wooden spoons? Copper pots? Silver forks? What materials has man used for making kitchen utensils throughout history? A new study now sheds light on the use of kitchen utensils made of copper.
At first thought, you would not expect hundreds of years old bones from a medieval cemetery to be able to tell you very much - let alone anything about what kinds of kitchen utensils were used to prepare food.
But when you put such a bone in the hands of Professor Kaare Lund Rasmussen, University of Southern Denmark, the bone begins to talk about the past.
HOUSTON -- A study conducted by researchers at The University of Texas MD Anderson Cancer Center demonstrated acceptable toxicity and anti-tumor activity in patients with four types of advanced, hard-to-treat rare cancers. Study findings were published in the March 17 online issue of the Journal for ImmunoTherapy of Cancer.
Wind shear pushed former Tropical Cyclone Herold apart and infrared imagery from NASA's Aqua satellite showed the system with very little strength remaining.
NASA's Aqua satellite uses infrared light to analyze the strength of storms by providing temperature information about the system's clouds. The strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
Annapolis, MD; March 19, 2020--In the fight to protect native ecosystems from invasive insects and related arthropod species, promising new tools are arising from rapid advances on a pair of research fronts: genetic analysis and geospatial technology.
Most technical functional units are built bit by bit according to a well-designed construction plan. The components are sequentially put in place by humans or machines. Life, however, is based on a different principle. It starts bottom-up with molecular self-assembly. The crystallization of sugar or salt are simple examples of self-assembly processes, where almost perfect crystals form from molecules that randomly move in a solution.
At a pivotal moment early in his career, Vittorio Gallo, Ph.D., was accepted to work with Professor Giulio Levi at the Institute for Cell Biology in Rome, a position that leveraged courses Gallo had taken in neurobiology and neurochemistry, and allowed him to work in the top research institute in Italy directed by the Nobel laureate, Professor Rita Levi-Montalcini.
Observing Phytoplankton via Satellite
Thanks to a new algorithm, researchers at the AWI can now use satellite data to determine in which parts of the ocean certain types of phytoplankton are dominant. In addition, they can identify toxic algal blooms and assess the effects of global warming on marine plankton, allowing them to draw conclusions regarding water quality and the ramifications for the fishing industry.
Someday, underwater robots may so closely mimic creatures like fish that they’ll fool not only the real animals themselves but humans as well. That ability could yield information ranging from the health of fish stocks to the location of foreign watercraft.
Such robots would need to be fast, efficient, highly maneuverable, and acoustically stealthy. In other words, they would have to be very much like bottlenose dolphins or killer whales.
