For much of the nation's food supply, removing unsafe products off of store shelves can take up to 10 months, according to news reports—even when people are getting sick.

Viruses attack the body by sending their genetic code—DNA and RNA—into cells and multiplying. A promising class of therapeutics that uses synthetic nucleic acids to target and shut down specific, harmful genes and prevent viruses from spreading is gaining steam.

Gears and mechanical transmissions are at home in the Emilia-Romagna region, the Motor Valley of northern Italy. A team of researchers from the University of Bologna and the Institute for Organic Synthesis and Photoreactivity of the National Research Council (Cnr-Isof) in Bologna, led by Massimo Baroncini and Alberto Credi, has planned, constructed and operated NanoGear, a device consisting of...

The Korea Institute of Machinery and Materials (KIMM) under the Ministry of Science and ICT developed a roll-based damage-free transfer technique that allows two-dimensional (2D) nanomaterials to be transferred into wafer scale without damage. The proposed technique has a variety of applications from transparent displays and semiconductors to displays for self-driving cars, and is expected to...

In our ongoing quest to transform into a more eco-friendly society, hydrogen (H2) is heralded as the clean fuel of tomorrow. Because H2 can be produced from water (H2O) without generating carbon emissions, developing H2-compatible technologies has become a top priority. However, the road ahead is bumpy, and many technical limitations must be ironed out.

Exposure to light is compulsory for photosynthetic organisms for the conversion of inorganic compounds into organic ones. However, if there is too much solar energy, the photosystems and other cell components could be damaged. Thanks to special protective proteins, the overexcitation is converted into heat—in the process called non-photochemical quenching. The object of the published study, OCP,...

When doctors or scientists want to peer into living tissue, there's always a trade-off between how deep they can probe and how clear a picture they can get.

A team of scientists from The Wistar Institute in Philadelphia and the Peter MacCallum Cancer Center in Melbourne, Australia, discovered a new checkpoint mechanism that fine-tunes gene transcription. As reported in a study published in Cell, a component of the Integrator protein complex tethers the protein phosphatase 2A (PP2A) to the site of transcription, allowing it to stop the activity of the...

In a study of low-income, urban youth in the U.S., researchers at Columbia University Mailman School of Public Health found that students exposed to Photovoice, an educational intervention, experienced greater improvements in STEM-capacity scores and environmental awareness scores compared to a group of youth who were not exposed to the activity. The results suggest that the Photovoice activities...

There are currently only a few synthetic agents that bind to and block the widespread membrane transport proteins, ATP-binding cassette transporters (ABC). Scientists at Goethe University and the University of Tokyo identified four of these macrocyclic peptides as models for a novel generation of active substances. They used methods for which the scientists involved are considered world leaders.

The scene at Pahokee marina on Lake Okeechobee last week was a warning sign: A thick mat of algae in various shades of green, brown, gray and fluorescent blue covered the area around boat slips. In some spots, the gunk was so dense it stuck out 2 inches above the water.

Europe's effort to make energy from American wood pellets is drawing complaints from Black community leaders in South Carolina, where manufacturers are expanding to produce more of the tiny wood chips.

A powerful cyclonic system, Tauktae, is expected to make landfall in the Indian state of Gujarat late Monday after barrelling up the Arabian Sea in the Indian Ocean.

A deadly cyclone blasted ashore in western India late Monday with fierce winds and drenching rains that turned streets into rivers, disrupting the country's response to its devastating Covid-19 outbreak.

Southern lesser galagos (Galago moholi), a species of primate that lives in southern Africa, boast big, round eyes and are so small they can fit in your hand.

The ocean is a big place with many deep, dark mysteries. Humans have mapped no more than 20% of the sea, and explored less. Even the kelp forests of Southern California—among the best studied patches of ocean on the planet—hide species not yet described by science.

As Covid-19 spread around the world, stock markets in individual countries took a major hit—yet stock markets in China where the disease first struck avoided significant falls—researchers at Lero, the Science Foundation Ireland Research Centre for Software found.

Air quality standards recommended by the American Thoracic Society (ATS) have the potential to prevent more illness and death than standards adopted by the U.S. Environmental Protection Agency (EPA), according to research presented at the ATS 2021 International Conference.

Archeologists at Northern Arizona University are hoping a new technology they helped pioneer will change the way scientists study the broken pieces left behind by ancient societies.

Since it was first signed more than five years ago, the Paris Agreement has set the bar for the global effort to reduce greenhouse gas emissions, with more than 70 countries taking on ambitious nationally determined contributions that exceed initial commitments laid out in the agreement. However, a new paper released today in Proceedings of the National Academy of Sciences argues that the carbon...

Data from the Jakobshavn drainage basin of the Central-Western Greenland ice sheet reveals that the distinct mark of this part of the ice sheet has reached a tipping point. That is the conclusion by Niklas Boers from Potsdam Institute for Climate Impact Research, Germany and Martin Rypdal from the Arctic University of Norway, after careful studies of the development in melt rates and ice-sheet...

Scientists studying the impact of record heat and drought on intact African tropical rainforests were surprised by how resilient they were to the extreme conditions during the last major El Niño event.

There are roughly 50 billion individual birds in the world, a new big data study by UNSW Sydney suggests—about six birds for every human on the planet.

Plant diseases don't stop at a nation's borders and miles of oceans don't prevent their spread, either. That's why plant disease surveillance, improved plant disease detection systems and predictive plant disease modeling—integrated at the global scale—are necessary to mitigate future plant disease outbreaks and protect the global food supply, according to a team of researchers in a new...
