Since the National Institute of Standards and Technology (NIST) built its first superconducting devices for counting photons (the smallest units of light) in the 1990s, these once-rare detectors have become popular research tools all over the world. Now, NIST has taken a step toward enabling universal standards for these devices, which are becoming increasingly important in science and industry.
Prior organic farming practices and plantings can have lasting outcomes for future soil health, weeds and crop yields, according to new Cornell University research.
A new study published in Science Advances found that certain types of materials have a "memory" of how they were processed, stored, and manipulated. Researchers were then able to use this memory to control how a material ages and to encode specific properties that allow it to perform new functions. This creative approach for designing materials was the result of a collaboration between Penn's...
An insurance and financial brokerage that fell victim to a ransomware attack has acknowledged for the first time it was aware of the incident for two months before publicly disclosing what...

Space plasma physicists develop algorithms to measure the buoyancy waves that appear in thin filaments of magnetic flux on Earth's nightside.
Scientists have developed a technique for the reversible conversion of 3D lipid vesicles into 2D ultra-thin nanosheets. Both the stable nanosheets and the reversible 2D-3D conversion process can find various applications in the pharmaceutical, bioengineering, food, and cosmetic sciences.
New research from neuroscientists shows that the brains of adolescents struggling with mental-health issues may be wired differently from those of their healthy peers.
As materials age, they 'remember' prior stresses and external forces, which scientists and engineers can then use to create new materials with unique properties.
Researchers have discovered how a brief disruption to a molecular pathway in the guts of mice before they are born can compromise adult immunity to a common and often deadly intestinal virus.
People can hardly imagine a city without night-time street lighting. But how do nocturnal animals such as bats respond to the illuminated urban landscape? In a recent study, scientists equipped common noctule bats (Nyctalus noctula) with mini GPS transmitters and recorded their trajectories in the sky above Berlin. They show that common noctules avoid brightly lit, built-up areas.
Pathogens can drive the evolution of social behavior in insects.
Students attending a high school in Germany can decide whether to begin the schoolday at the normal early time or an hour later. According to chronobiologists, the measure has had a positive effect on both their sleep and learning experience.
New research could lead to an improved vaccine to protect against the bacterium, Neisseria meningitides that causes sepsis and meningitis.
Why do we move our eyes fast in the paradoxical sleep -- in that sleep phase, in which most dreams take place? The secret is not yet fully aired, but we are on his track: A team has identified the nerve cells behind this curious phenomenon.
Popular gym chains across the country capitalize on the broad desire to get healthy in the New Year with persuasive post-holiday marketing campaigns, but they're also undermining public health warnings about the dangers of indoor tanning, according to a new study.
Engineers have come up with an alternative to conventional ultrasound that doesn't require contact with the body to see inside a patient. The new laser ultrasound technique leverages an eye- and skin-safe laser system to remotely image the inside of a person.
Always on the lookout for better ways to measure all kinds of things, researchers have published a detailed study suggesting an "elegant" improved definition for the standard unit of light power, the optical watt. The proposed definition promises a more precise, less expensive and more portable method for measuring this important quantity for science, technology, manufacturing, commerce and...
Researchers offer an updated vision of the steps that 143 countries around the world can take to attain 100% clean, renewable energy by the year 2050. The new roadmaps project that transitioning to clean, renewable energy could reduce worldwide energy needs by 57%, create 28.6 million more jobs than are lost, and reduce energy, health, and climate costs by 91% compared with a business-as-usual...
Fires and logging could trigger a process called "dieback," in which the rainforest would dry up, burn, and become a savanna-like...
Haplotypes are a set of genetic variations that, located side by side on the same chromosome, are transmitted in a single group to the next generation. Their examination makes it possible to understand the heritability of certain complex traits, such as the risk of developing a disease. However, to carry out this analysis, genome analysis of family members (parents and their child) is usually...

Findings from a recent research project, conducted by a Marshall University scientist and assistant professor in the Marshall University College of Science, with researchers in Texas, was recently published in the December issue of the prestigious online journal, Nature Communications.
Purchasing luxury goods can affirm buyers' sense of status and enjoyment of items like fancy cars or fine jewelry. However, for many consumers, luxury purchases can fail to ring true, sparking feelings of inauthenticity that fuel what researchers have labeled the "impostor syndrome" among luxury consumers.
A simple photograph taken with a mobile phone is able to detect irregularities in the labelling of rice, according to an investigation conducted by the Complutense University of Madrid (UCM) and the Scintillon Institute of San Diego (USA).
Light propagation is usually reciprocal, meaning that the trajectory of light travelling in one direction is identical to that of light travelling in the opposite direction. Breaking reciprocity can make light propagate only in one direction. Optical components that support such unidirectional flow of light, for example isolators and circulators, are indispensable building blocks in many modern...
Cellular origin is well explained by the "endosymbiotic theory," which famously states that higher organisms called "eukaryotes" have evolved from more primitive single-celled organisms called "prokaryotes." This theory also explains that mitochondria—energy-producing factories of the cell—are actually derived from prokaryotic bacteria, as part of a process called "endosymbiosis." Biologists...
Rice provides daily subsistence for about three billion people worldwide and its output must keep pace with a growing global population. In light of this, the identification of genes that enhance grain yield and composition is much desired. Findings from a research project led by Professor Mee-Len Chye, Wilson and Amelia Wong Professor in Plant Biotechnology from the School of Biological Sciences...
In August 2017, a marine accident occurred in the Pearl River Estuary where a cargo vessel accidentally released about 1,000 tonnes of palm stearin into the sea. Over 200 tonnes of palm stearin reached the southwest coasts of Hong Kong. The general public and green groups expressed concerns that such palm oil pollution could adversely affect the marine life and marine ecosystem, yet there was a...
Paul Davies' newest book, The Demon in the Machine, takes aim at one of the great outstanding scientific enigmas—what is life, how and why does it emerge and what distinguishes the living from the non-living? The book, which was published this past October in the U.S. has now been named the top physics book of 2019 by Physics World, a publication of the UK Institute of Physics.
Coastal wetlands provide stunning views and are hosts to a vast array of biodiversity. But they also provide another service to the warming Earth: they capture carbon from the atmosphere and sequester it in their sediment at high rates. In the United States alone, coastal wetlands can offset the yearly carbon dioxide emissions from 800,000 cars. But as sea level rises with climate change, will...
Flooding accounts for a third of the average annual economic losses caused by natural disasters worldwide. Flood damage resulting from typhoons and torrential rainfall is increasing each year; thus, flood prediction is a valuable strategy for disaster reduction. Predicting floods is the key component of an effective early warning system, giving governments, businesses, and individuals precious...
