It is not unusual to come across headlines about pollution or global warming and find that they reach different conclusions depending upon the data source.

An international collaboration between researchers at Harvard University and Yunnan University in China uses microCT to study and restudy arthropod fossils from the early Cambrian in the Chengjiang biota in the Yunnan Province of China. Their latest study shows with unprecedented clarity the head morphology of the species Leanchoilia illecebrosa and demonstrates the presence of a labrum thus...
A team of researchers at the Department of Energy's Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease—the enzyme that enables the virus to reproduce.
The UN's weather agency announced Thursday the longest lightning bolt on record—a single flash in Brazil on October 31, 2018 that cut the sky across more than 700 kilometers.
Scientists working remotely with Schmidt Ocean Institute, one of the only at-sea science expeditions to continue operating during the global pandemic, have completed afirst look at deep waters in the Coral Sea never before seen.
Deny it you might, but even modest consumers brag about their purchases every once in a while. But can marketers leverage our tendency to brag about our buys to market products or services more successfully?
Confronting a white person who makes a racist or sexist statement can make them reflect on their words and avoid making biased statements about race or gender in the future, Rutgers researchers find.
Acknowledging health as a universal human right could galvanize people and organizations to make major improvements in health worldwide, according to new research from faculty at Binghamton University, State University of New York.
A new study shows that the central bank tool known as quantitative easing helped consumers substantially during the last big economic downturn—a finding with clear relevance for today's pandemic-hit economy.
Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for data transmission on the internet even more efficient and compact.
The discovery of carbon nanostructures like two-dimensional graphene and soccer ball-shaped buckyballs helped to launch a nanotechnology revolution. In recent years, researchers from Brown University and elsewhere have shown that boron, carbon's neighbor on the periodic table, can make interesting nanostructures too, including two-dimensional borophene and a buckyball-like hollow cage structure...
In a new study led by scientists at Point Blue Conservation Science and in collaboration with The Institute for Bird Populations, authors evaluated the successes of mountain meadow restorations by analyzing eight years of bird data collected by field biologists. The authors concluded that, when "pond and plug" and similar techniques were followed, the number of birds of many species increased over...
The nearest exoplanets to us provide the best opportunities for detailed study, including searching for evidence of life outside the solar system. In research led by the University of Göttingen, the RedDots team of astronomers has detected a system of super-Earth planets orbiting the nearby star Gliese 887, the brightest red dwarf star in the sky. Super-Earths are planets which have a mass higher...
The sun's magnetic activity follows an 11-year cycle. Over the course of a solar cycle, the sun's magnetic activity comes and goes. During solar maximum, large sunspots and active regions appear on the sun's surface. Spectacular loops of hot plasma stretch throughout the sun's atmosphere and eruptions of particles and radiation shoot into interplanetary space. During solar minimum, the sun calms...
Led by the Ikerbasque professor Luis Liz-Marzán, researchers at the Centre for Cooperative Research in Biomaterials CIC biomaGUNE have developed a mechanism by which gold atoms are deposited by means of chemical reduction onto previously formed gold nanorods to produce a quasi-helicoidal structure (the particles acquire chirality). This geometry enables these "nanoscrews" to interact with...
When sunlight shining on a leaf changes rapidly, plants must protect themselves from the ensuing sudden surges of solar energy. To cope with these changes, photosynthetic organisms—from plants to bacteria—have developed numerous tactics. Scientists have been unable, however, to identify the underlying design principle.
Graphene nanoribbons might soon be much easier to produce. An international research team led by Martin Luther University Halle-Wittenberg (MLU), the University of Tennessee and Oak Ridge National Laboratory in the U.S. has succeeded in producing this versatile material for the first time directly on the surface of semiconductors. Until now, this was only possible on metal surfaces. The new...
In a step toward better control of the mosquitoes that transmit malaria, researchers have mapped the patterns of insecticide resistance in Anopheles gambiae mosquitoes across Africa. The new study, published June 25, 2020 in the open-access journal PLOS Biology by Catherine Moyes and Penelope Hancock of the University of Oxford, UK, and collaborators, found that resistance to five mainstream...
Whole genome duplication followed by massive gene loss has shaped many genomes, including the human genome. Why some gene duplicates are retained while most perish has puzzled scientists for decades.
Astronomers have discovered the most massive quasar known in the early universe, containing a monster black hole with a mass equivalent to 1.5 billion suns. Formally designated as J1007+2115, the newly discovered quasar is one of only two known from the same cosmological period. Quasars are the most energetic objects in the universe, and since their discovery, astronomers have been keen to...
Dogs play an important role in human life all over the world—whether as a family member or as a working animal. But where the dog comes from and how old various groups of dogs are is still a bit of a mystery.
Russia's Energia space corporation said Thursday it will take the first tourist on a space walk in 2023, under the terms of a new contract with a US partner.
Sure, you've got a product that says "kills germs" under your sink, but will it really destroy the new coronavirus on surfaces?
The coronavirus pandemic, suspected of originating in bats and pangolins, has brought the risk of viruses that jump from wildlife to humans into stark focus.
You can now see how coronavirus lockdowns have changed air pollution, hospital lights and even white asparagus harvests.
