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.

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...

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.

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. Using an electron microscope, Professor Mahmood Reza Amiry-Moghaddam and his colleagues can investigate the ultra-small structures in a cell.

In a week when the UK Prime Minister Boris Johnson has admitted to breaking COVID-19 lockdown rules, a new study has found that impartial, transparent and truthful government communications are fundamental for achieving and maintaining government trust during public health emergencies.

New results from a long-running public opinion survey show that about 1 in 3 Americans is now "alarmed" by global warming. Is it any wonder, given the horrific onslaught of fires, floods, heat waves and other climate disasters we've experienced in the last year alone?

Aliena, a tech spin-off from Nanyang Technological University, Singapore (NTU Singapore), has today deployed into space a nanosatellite fitted with a fuel-efficient engine it has developed. The nanosatellite was sent from the SpaceX Falcon 9's Transporter-3 mission which launched from Cape Canaveral Space Force Station, Florida, US.

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 study published in Nature Medicine.

If renewable energies are one day to replace fossil fuels, engineers need to find a way to store it reliably and on a large scale. One method that numerous researchers are currently studying involves storing the energy in gaseous form inside electrolytic cells.

A team of researchers working at Stanford University has used time dilation in an atomic fountain to measure the curvature of space-time. In their study, reported in the journal Science, the group used the fountain as an interferometer to measure atomic wave packet changes that corresponded to phase shifts. Albert Roura,with the German Aerospace Center's Institute of Quantum Technologies published...

The current wet conditions delivered by La Niña may have caused widespread flooding, but they've also provided a reprieve from the threat of bushfires in southeastern Australia. This is an ideal time to consider how we prepare for the next bushfire season.

Conservationists and veterinarians are warning that plastic waste in an open landfill in eastern Sri Lanka is killing elephants in the region, after two more were found dead over the weekend.

While Australians are used to summer heat, most of us only have to endure the occasional day over 40 degrees Celsius.

When hurricanes Eta and Iota barrelled into Central America in November 2020, they flooded towns and cities, caused catastrophic losses in the agricultural sector and contributed to food insecurity. In all, 4.7 million Hondurans were affected, and tens of thousands decided to leave, forming migrant caravans in a desperate attempt to rebuild their lives in the United States.

A powerful earthquake shook parts of Indonesia's main island of Java on Friday, damaging buildings and houses and sending people into the streets, but there were no immediate reports of casualties. Officials said there was no danger of a tsunami.
