You may be able to help NASA's Curiosity rover drivers better navigate Mars. Using the online tool AI4Mars to label terrain features in pictures downloaded from the Red Planet, you can train an artificial intelligence algorithm to automatically read the landscape.
The NASA official who managed the inaugural private crewed flight into space last month has been promoted to become the first female head of human spaceflight, the agency said Friday, as it prepares to return people to the Moon in 2024.
Earth's temperature spiked to tie a record high for May, U.S. meteorologists reported Friday.
A new interdisciplinary study published in the journal Science Advances reports on 20 newly sequenced ancient genomes from sub-Saharan Africa, including the first genomes from the Democratic Republic of the Congo, Botswana, and Uganda. The study documents the coexistence, movements, interactions and admixture of diverse human groups during the spread of food production in sub-Saharan Africa.
In a new study, researchers recently discovered that Indonesia's national anti-poverty program reduced deforestation by about 30%.
The origins of human innovation have traditionally been sought in the grasslands and coasts of Africa or the temperate environments of Europe. More extreme environments, such as the tropical rainforests of Asia, have been largely overlooked, despite their deep history of human occupation. A new study provides the earliest evidence for bow-and-arrow use, and perhaps the making of clothes, outside...
A team of researchers led by IPK Gatersleben has succeeded in providing answers to a long unsolved question in the breeding of plant hybrids. Their conclusions: the more diverse in genetics, than better, but only in cases of similar preferences.
Deforestation continued to surge in the Brazilian Amazon last month, according to official figures released Friday, showing it was the worst May and worst first five months of the year on record.
Ukrainian scientist Oleksandr Borsuk looks bitterly at the charred trunks of old pine trees as the acrid smell of burnt wood hangs in the air.
A low-pressure system that developed in the Philippine Sea and tracked over the central Philippines has moved into the South China Sea and become a depression. NASA's Terra satellite provided an image of the newly formed storm.
Here's some good news for U.S. states trying to spur an economic recovery in the years ahead: The R&D tax credit has a significant effect on entrepreneurship, according to a new study led by an MIT professor.
Pittsburgh research coauthored by team from the Department of Physics and Astronomy reveals that optical fields have the ability to modify electronic properties of a solid.
Like most galaxies, the Milky Way hosts a supermassive black hole at its center. Called Sagittarius A*, the object has captured astronomers' curiosity for decades. And now there is an effort to image it directly.
A new study from Lund University in Sweden shows that female birds benefit more from extra food in the winter. If females receive additional food, they do not need to reduce their body temperature as much as they would have otherwise, and the chances of surviving cold nights increase.
Colored smoke is increasingly employed as an element of spectacle in a broad spectrum of public events. However, the chemicals used for this purpose give rise to toxic by-products. LMU chemists have now developed a safe alternative.
The Higgs boson was discovered by the ATLAS and CMS Collaborations at CERN's Large Hadron Collider (LHC) in 2012 through its decays into pairs of photons, W bosons and Z bosons. Since then, physicists at these experiments have gained great insight into the properties of the Higgs boson through the study of its different production and decay processes. Decays to pairs of tau leptons and bottom...
Chemists at RIKEN have discovered why shining light on silver nanoparticles causes oxygen molecules attached to their surfaces to break off. This insight will help researchers design new catalysts that harness light energy.
A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in autumn 2017, is still bothering Europe's radiation protection entities. Although the activity concentrations were innocuous, they reached up to 100 times the levels of what had been detected over Europe in the aftermath of the Fukushima accident. Since no government had assumed responsibility, a military...
Physicians must be competent collaborators with team members in order to practice medicine effectively. Health professional students have limited opportunities to work and learn together during the course of their medical education. Not only is it important for students to acquire prodigious knowledge, they must also learn how to collaborate well, and the results of their efforts must be evaluated...
Nearly 13 kilometers per year: that is the rate at which the wintering area of Bewick's swans has shifted east over the past 50 years. It's a discovery with consequences for the conservation of this migratory species, writes a team of researchers led by the Netherlands Institute of Ecology (NIOO-KNAW) in Global Change Biology.
What nitrogen is getting up to in permafrost soils may be much more interesting than researchers have long believed—with potentially significant consequences for our management of climate change.
A group of experts from the University of Seville has carried out a comparative study of the concentrations—both totals as well as fractions—of the metals found in sediment in the River Guadiamar in 2002 with those present in the same area in 2018. After this study, the researchers state that there has been an important fall in the total concentrations, and evolution of the metal fraction...
Researchers at Japan Advanced Institute of Science and Technology (JAIST) graduate student Kulisara Budpud, Assoc. Prof. Kosuke Okeyoshi, Dr. Maiko Okajima and, Prof. Tatsuo Kaneko reveal a unique polysaccharide fiber in a twisted structure forming under a drying process which showed spring-like behavior. The spring-like behavior of twisted structures is practically used as a reinforced structure...
The Copernicus Sentinel-2 mission takes us over Barcelona—the second largest city in Spain.
Trade unions are crucial in advancing workers' rights, but it is unhelpful to consider their leaders as representatives of the working class as a whole when analysing labour relations and government policies, a new paper from the University of Warwick Department of Sociology argues.
