The Arctic Ocean has been getting warmer since the beginning of the 20th century — decades earlier than records suggest — due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean. Cambrigde, Nov 29, 2021.- An international group of researchers reconstructed the recent history of oceanContinuar Leyendo
Physicists have created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for quantum computing and advance research into unconventional superconductivity and quantum criticality. Espoo,Continuar Leyendo
Immune checkpoint inhibitors can boost the immune system’s response to tumor cells, but the medications tend to be ineffective against certain cancers, especially colorectal and pancreatic cancers. A new clinical trial led by investigators at Massachusetts General Hospital (MGH) indicates that combining radiation with immune checkpoint inhibitors may be anContinuar Leyendo

The tapered cone shell is popular among seashell collectors for its colorful patterns, but the smooth mottled shells are also home to the cone snail which is capable of spewing a potent insulin-like venom that can paralyze its prey. Researchers at the University of New Hampshire have found that variantsContinuar Leyendo
A team of researchers led by UC Riverside has demonstrated for the first time one way that a small molecule turns a single cell into something as large as a tree. For half a century, scientists have known that all plants depend on this molecule, auxin, to grow. Until now,Continuar Leyendo
Professor Norikazu Ichihashi and his colleagues at the University of Tokyo have successfully induced gene expression from a DNA, characteristic of all life, and evolution through continuous replication extracellularly using cell-free materials alone, such as nucleic acids and proteins for the first time. Tokio, Nov 20, 2021.- The ability toContinuar Leyendo
The ancient Maya had stone temples and palaces in the rainforest of Central America, along with dynastic records of royal leaders carved in stone, but they lacked a basic commodity essential to daily life: salt. The sources of salt are mainly along the coast, including salt flats on the YucatanContinuar Leyendo
París, Nov 19, 2021.- Solar Orbiter is returning to Earth for a flyby before starting its main science mission to explore the Sun and its connection to ‘space weather’. During the flyby Solar Orbiter must pass through the clouds of space debris that surround our planet, making this manoeuvre theContinuar Leyendo
People with Prader Willi syndrome, a genetic disorder, have an insatiable appetite. They never feel full, even after a hearty meal. The result can be life-threatening overeating and obesity. Philadelphia, Nov 18, 2021.- According to a new study, their constant hunger results in part to disordered signaling in the brain’sContinuar Leyendo
