Intertropical Convergence Zone limits climate predictions in the tropical Atlantic

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.

Scientists offer road map to improve environmental observations in the Indian Ocean

(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.

Research breaks new ground in understanding how a molecular motor generates force

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.

Physical virology shows the dynamics of virus reproduction

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.

Human-induced climate change caused the northwestern Pacific warming record in August 2020

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.

SpaceX Cargo Dragon succeeds in 1st autonomous undocking

SpaceX’s CRS-21 Cargo Dragon undocked from the International Space Station’s Harmony module on January 12, 2021, succeeding in the world’s first-ever autonomous undocking and testing of several new vehicle upgrades.

Study of flowers with two types of anthers solves mystery that baffled Darwin

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.
