The omicron variant is sickening so many sanitation workers around the U.S. that some cities have had to delay or suspend garbage or recycling pickup, angering residents shocked that governments can't perform this most basic of functions.
Insecticides play a central role in efforts to counter global impacts of mosquito-spread malaria and other diseases, which cause an estimated 750,000 deaths each year. These insect-specific chemicals, which cost more than $100 million to develop and bring to market, also are critical to controlling insect-driven crop damage that poses a challenge to food security.
The atomic nucleus is a tough nut to crack. The strong interaction between the protons and neutrons that make it up depends on many quantities, and these particles, collectively known as nucleons, are subject to not only two-body forces but also three-body ones. These and other features make the theoretical modeling of atomic nuclei a challenging endeavor.
Addressing one of the most profoundly unanswered questions in biology, a team has discovered the structures of proteins that may be responsible for the origins of life in the primordial soup of ancient Earth.
Researchers have developed a new water-splitting process and material that maximize the efficiency of producing green hydrogen, making it an affordable and accessible option for industrial partners that want to convert to green hydrogen for renewable energy storage instead of conventional, carbon-emitting hydrogen production from natural gas.
Before the introduction of the domestic horse in Mesopotamia, valuable equids were being harnessed to ceremonial or military four wheeled wagons and used as royal gifts, but their true nature remained unknown. According to a palaeogenetic study, these prestigious animals were the result of a cross between a domestic donkey and a wild ass from Syria, now extinct. This makes them the oldest example...
Bob McDonald's blog: Two studies outline the sources and the ubiquity of microplastic pollution in the environment, but if we stop this at its source, we can reduce potential...
The next "giant leap" for humans may be a trip to Mars, but having enough oxygen-carrying red blood cells for the journey might present a challenge, new research...
Whether you are taking a muscle relaxant or a heart medication, you are possibly using a medication that contains a synthetically produced benzoxazole. Although natural benzoxazoles show more significant promise in pharmaceuticals, their time to develop organically and inherent undesired properties impede their usage.
Addressing one of the most profoundly unanswered questions in biology, a Rutgers-led team has discovered the structures of proteins that may be responsible for the origins of life in the primordial soup of ancient Earth.
Long-running conflicts, such as that between Israel and Palestine, are inflamed by the political process itself as politicians adopt tough 'hawkish' policies to get themselves re-elected, according to a new study.
The 4,500-year-old iconography and texts from Mesopotamia show that the elite used equids for travel and warfare; however, the nature of these animals remained mysterious. In Science Advances (January 14, 2022), a team from the Institut Jacques Monod (CNRS/Université de Paris) used ancient DNA to show that these animals were the result of crossing domestic donkeys with wild asses. This makes them...

The past two years of pandemic-related challenges have accelerated the adoption of cloud across industry at an unprecedented rate. This increased investment in cloud can serve to reinvigorate sustainability goals and provide the ability to measure the impact of an investment. The consequences of climate change are no longer theoretical, and corporate leaders are taking responsibility. While many...
Archeologists from The University of Western Australia have discovered people who lived in north-west Arabia in the Early to Middle Bronze Age built 'funerary avenues'—long-distance corridors linking oases and pastures, bordered by thousands of elaborate burial monuments.
But experts are confident worst case scenarios for current Covid wave unlikely to occurCoronavirus – latest updatesSee all our coronavirus coverageScientists advising the government have predicted there will be a fresh wave of Omicron cases in the early summer as people resume social activities and immunity wanes.But experts on the Scientific Advisory Group for Emergencies (Sage) said they were...
The Internet of Things (IoT) is completely enmeshed in our daily lives, a network of connected laptops, phones, cars, fitness trackers -- even smart toasters and refrigerators -- that are increasingly able to make decisions on their own. But how to ensure that these devices benefit us, rather than exploit us or put us at risk? New work proposes a novel framework, the 'impact universe,' that can...
A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a new study.
A new study has identified a set of cellular receptors for at least three related alphaviruses shared across mosquitoes, humans, and animals that host the virus.
Scientists have pinpointed a gene that helps deadly E. coli bacteria evade antibiotics, potentially leading to better treatments for millions of people worldwide.
Researchers studying how small worms defend themselves against pathogens have discovered a gene that acts as a first-line response against infection. They identified 'ZIP-1' as a centralized hub for immune response, a finding could have implications for understanding human immunity against viruses.
Researchers show that high-frequency plasma waves in the Geospace can generate low-frequency plasma waves through wave-particle interactions by heating up low-energy ions, unveiling a new energy transfer pathway in collisionless plasma.
Just like explorers need maps, scientists require guides to better understand and advance new technology. A neuromorphic device, which can mimic the neural cells in our brain, has lacked such a guideline and created headaches for scientists trying to understand their operational mechanisms. That is until now after a research group created a map that provides rational design guidelines for...
Researchers have completed a comprehensive analysis of the head width of over 1500 modern and fossilized species of termites and determined that their size isn't shrinking at a geological timescale.
Being the first element to form, hydrogen holds clues about the distribution of matter in our universe. Normally a gas, hydrogen exists as a solid under ultra-high-pressure conditions commonly found in the core of giant gaseous planets. However, the structures of solid hydrogen have remained elusive owing to difficulties in replicating such conditions experimentally. Now, a new study sheds light...
Do we have our best ideas while walking? Indeed, but even small movements while sitting improve creativity, as two researchers have discovered.
Researchers have demonstrated in the lab how well a mineral common at the boundary between the Earth's core and mantle conducts heat. This leads them to suspect that the Earth's heat may dissipate sooner than previously thought.
We now know of almost 5,000 planets outside the Solar System. If you were to picture what it would be like on one of these distant worlds, or exoplanets, your mental image would probably include a parent star—or more than one, especially if you're a Star Wars fan.
An attempt to feed starving manatees appears to have failed so far, as the big marine mammals refuse to recognize floating lettuce as food.
The Acropolis of Athens counts among the world's greatest architectural and artistic monuments. Visitors come to admire the marble buildings that testify to the glory of Ancient Greece more than two millennia ago. Typically, only little attention is paid to the site's rich medieval and Ottoman history. But one of the few stories commonly told about this period concerns the temple with six iconic...
If you've seen water drops dance and jitter on a hot pan or griddle, you've seen the Leidenfrost effect in action. Or you may have seen the "Mythbusters" episode where Adam and Jamie thrust their wet fingers and hands into molten lead and pulled them out unharmed.
One of the laboratories at the Institute of Basic Medical Sciences houses equipment worth many millions of kroners. Few research groups have the resources to buy an electron microscope when conducting scientific research.
