Photosystem II is a protein complex in plants, algae and cyanobacteria that is responsible for splitting water and producing the oxygen we breathe. Over the past few years, an international collaboration between scientists at the Department of Energy's Lawrence Berkeley National Laboratory, SLAC National Accelerator Laboratory and several other institutions have been able to observe various steps...
As the world increasingly turns to aqua farming to feed its growing population, there's no better time than now to design an aquaculture system that is sustainable and efficient.
Before there were animals, bacteria or even DNA on Earth, self-replicating molecules were slowly evolving their way from simple matter to life beneath a constant shower of energetic particles from space.
NASA satellites have been providing forecasters with various types of imagery on Typhoon Amphan as it heads toward a landfall near the border of eastern India and Bangladesh on May 20.
From testing drugs to developing vaccines, the close study of the immune system is key to improving real-world health outcomes. T-cells are integral to this research, as these white blood cells help tailor the body's immune response to specific pathogens.
Conventional wisdom suggests that when a company generates more carbon emissions, investors should lower its stock price. After all, the company is generating a socially undesirable byproduct.
Rapidly rising water has overtaken dams and forced the evacuation of about 10,000 people from flooded communities in central Michigan, and the governor warned that one city could end up "under approximately 9 feet of water" Wednesday.
Researchers have developed a new strategy that uses optical coherence tomography (OCT) to acquire both the surface and underlying details of impressionist style oil paintings. This information can be used to create detailed 3-D reconstructions to enhance the viewing experience and offer a way for the visually impaired to experience paintings.
NASA-NOAA's Suomi NPP satellite passed over the western North Atlantic Ocean and provided forecasters with a visible image of Post Tropical Storm Arthur.
Organic field-effect transistors (OFETs) are the heart of plastic electronics. Doping has been shown to improve the performance of OFETs effectively. There are two major ways of doping OSCs.
For the first time, monolayers of transition metal dichalcogenides with excellent optical properties were grown. A team of physicists from the University of Warsaw managed to overcome the technical difficulties faced by industry and scientists from around the world—namely the very limited size, heterogeneity, and broadening of the spectral lines of fabricated materials. Monolayers without these...
A recent analysis of discourse on Facebook highlights how social media and an individual's sense of identity can be used to dehumanize entire groups of people.
Fires are one of the greatest threats to forest heritage. According to data from the Ministry of Agriculture, on average more than 17,000 fires occur per year in Spain, affecting 113,000 hectares and causing enormous financial and scenic losses.
In recent years, topology has emerged as an important tool to classify and characterize properties of materials. It has been found that many materials exhibit a number of unusual topological properties, which are unaffected by deformations, e.g., stretching, compressing, or twisting. These topological properties include quantized Hall currents, large magnetoresistance, and surface excitations that...
A study by a team of researchers from Canada and Italy recently published in Nature Materials could usher in a revolutionary development in materials science, leading to big changes in the way companies create modern electronics.
A new study from the University of Central Florida has confirmed and quantified, for the first time, the presence of microplastics in terrestrial and aquatic birds of prey in Florida, including hawks, ospreys and owls.
Preserving biodiversity is one of the key debates of our time—but another subject of hot debate in recent decades among evolutionary experts is how biodiversity has changed over the past few hundred million years. New findings are challenging the conventional view on this.
Springtime rains can be a surprising source of pollen.
It might sound like science fiction, but scientists are preparing to build colonies on the moon and, eventually, Mars. With NASA planning its next human mission to the moon in 2024, researchers are looking for options to power settlements on the lunar surface. According to a new article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, nuclear fission...
Entrepreneurial motivation is important to economic growth because entrepreneurs create companies that produce new products and services, which in turn, boost productivity. But we know little about what motivates innovative entrepreneurs and how their motivations differ by gender, culture and other characteristics. A new study from researchers at Carnegie Mellon University and Columbia Business...
"Orthonectida is a group of parasitic creatures that was discovered long ago—in 1877. However, their position in the animal system until recently remained a mystery," said George Slyusarev, Professor at St Petersburg University and Doctor of Biology. "Initially, they were considered extremely primitive animals that occupy an intermediate position between Protozoans and Metazoans. Hence, their...
Children of parents with a degree are almost a year of schooling ahead in maths by the age 11 than peers whose parents have just GCSEs, a new study by the University of Sussex has discovered.
Fluctuations in the Pacific Walker circulation (PWC), a zonally-oriented overturning cell across the tropical Pacific, can cause widespread climatic and biogeochemical perturbations. It remains unknown how the PWC developed during the Cenozoic era, with its substantial changes in greenhouse gases and continental positions.
For the first time, seismologists can characterize signals as a result of some industrial human activity on a continent-wide scale using cloud computing. In two recently published papers in Seismological Research Letters, scientists from Los Alamos National Laboratory demonstrate how previously characterized "noise" can now be viewed as a specific signal in a large geographical area thanks to an...
