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 the oldest known example of animal hybrids, which were produced by Syro-Mesopotamian societies 500 years... Читать дальше...

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 sculptures of maidens, the so-called Caryatids.

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 a Perspective piece in the same journal issue outlining the work by the team in California.

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.

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.

Since early 2020, our way of life has changed dramatically. COVID-19 has transformed how we study, learn and work—even how we shop, eat and gather.

Four Asian countries—the Philippines, Indonesia, Malaysia and India—aim to restore 47.5 million hectares of degraded land by 2030. This is roughly equal to the size of Sumatra, Indonesia's third biggest island.

From the first piggy bank to the first credit card, teaching children proper money management and budgeting habits takes both time and patience. But the value of helping kids develop financial literacy shouldn't be understated.

Sunlight up in Earth orbit is 10 times more intense than down on Earth's surface, so the idea is to fly dedicated satellites to capture solar energy, then beam it down to Earth—and potentially the Moon or other planets further into the future.

When it comes to the business of seafood, COVID-19 hasn't been nearly as damaging as the ecological havoc caused by humans, a recent global survey of fish farms found.
