Mexico says pig die-off due to salmonella, pneumonia

Mexican authorities breathed a sigh of relief Friday when experts determined that a die-off of pigs in December at a local slaughterhouse was due to salmonella and Pasteurellosis, a commonly occurring infection, and not African swine fever.

South prepares for weekend threat of debilitating snow, ice

Weather forecasters' predictions of debilitating snow and ice as far south as Georgia sent parts of the region into a tizzy Friday with shoppers scouring store shelves for storm supplies and road crews trying to prevent a repeat of past wintertime debacles.

Hubble views a tranquil galaxy with an explosive past

The lazily winding spiral arms of the spectacular galaxy NGC 976 fill the frame of this image from the NASA/ESA Hubble Space Telescope. This spiral galaxy lies around 150 million light-years from the Milky Way in the constellation Aries. Despite its tranquil appearance, NGC 976 has played host to one of the most violent astronomical phenomena known – a supernova explosion. These...

Genetic strategy reverses insecticide resistance

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.

Advances in theoretical modeling of atomic nuclei

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.

Genetically engineered E. coli could improve drug development

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.

New study sheds light on origins of life on Earth

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.

Before horses, ass hybrids were bred for warfare

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...

Archaeologists discover ancient highways in Arabia

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.

A Turkish harem on the Acropolis? It's most likely a Greek myth

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...

Levitating and colliding liquid drops

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.
