The strongest climate fluctuation on time scales of a few years is the so-called El Niño phenomenon, which originates in the Pacific. A similar circulation pattern exists in the Atlantic, which scientists have now studied in more detail. Their results contribute to a better understanding of this climate fluctuation and pose a challenge for prediction models.
Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA.
(University of Miami Rosenstiel School of Marine & Atmospheric Science) A group of more than 60 scientists have provided recommendations to improve the Indian Ocean Observing System (IndOOS), a basin-wide monitoring system to better understand the impacts of human.
A team of biophysicists set out to tackle the long-standing question about the nature of force generation by myosin, the molecular motor responsible for muscle contraction. The key question they addressed – one of the most controversial topics in the field – was: how does myosin convert chemical energy, in the form of ATP, into mechanical work? The answer revealed new details into how myosin, the engine of muscle and related motor proteins, transduces energy.
The reproductive cycle of viruses requires self-assembly, maturation of virus particles and, after infection, the release of genetic material into a host cell. New physics-based technologies allow scientists to study the dynamics of this cycle and may eventually lead to new treatments.
A new study revealed that the record-warm sea surface temperature over the northwestern Pacific in August 2020 could not be expected to occur without human-induced climate changes. Such extremely warm condition is likely to become a new normal climate in August by the mid-21st century, needing the prompt implementation of adaptation measures for anthropogenic global warming.
The first comet to be found in 2021 – labeled C/2021 A1 (Leonard) – might become the brightest comet of this year! Charts and more info here.
SpaceXâs CRS-21 Cargo Dragon undocked from the International Space Stationâs Harmony module on January 12, 2021, succeeding in the worldâs first-ever autonomous undocking and testing of several new vehicle upgrades.
Most flowering plants depend on pollinators such as bees to transfer pollen from the male anthers of one flower to the female stigma of another flower, enabling fertilization and the production of fruits and seeds. Bee pollination, however, involves an inherent conflict of interest, because bees are only interested in pollen as a food source. A new study describes a pollination strategy involving flowers with two distinct sets of anthers that differ in color, size, and position.
