  • Monoterpene emissions from vegetation are more sensitive to temperature than previously thought and are primarily governed by plant functional type with warmer ecosystems appearing to be more sensitive, according to a meta-analysis of monoterpene emission data published between 1980 and 2020.

    • Efstratios Bourtsoukidis

    Volume: 5, P: 1-10

  • Kinesin-1 utilizes ATP-driven conformational changes to transport vital intracellular cargoes along microtubules. The authors use cryo-EM to reveal a missing structural transition state of the kinesin-1 motor domain during ADP release that is unaffected by its autoinhibitory tail.

  • Aircraft measurements over the Amazon show that new particle formation in the upper troposphere emerges when isoprene, emitted by forests, undergoes oxidation in the presence of nitrogen oxides produced by lightning.

  • Biomass combustion smoke transported from Africa accounts for about 60% of black carbon concentrations in the central Amazon during the rainy season, according to long-term measurements of refractory black carbon in 2019 and 2020

  • Recent measurements in the Amazon rainforest indicate missing sources of volatile organic compounds (VOCs). Here the authors show that soil microorganisms are a strong, unaccounted source of highly reactive sesquiterpenes, a class of VOCs that can regulate ozone chemistry within the forest canopy.

  • The effective hygroscopicity of organic matter and inorganic ions in atmospheric aerosols can be efficiently and accurately parameterized by global average values to constrain a critically important aspect in climate and Earth system models

  • By performing experiments under upper tropospheric conditions, nitric acid, sulfuric acid and ammonia can form particles synergistically, at rates orders of magnitude faster than any two of the three components.

  • The Middle East is known to emit large amounts of non-methane hydrocarbon pollutants to the atmosphere, but the sources are poorly characterized. Here the authors discover a new source—deep water in the Red Sea—and calculate that its emissions exceed rates of several high gas-production countries.

  • Fine particulate aerosols sampled around the Arabian Peninsula predominantly originate from anthropogenic pollution and constitute one of the leading health risk factors in the region, according to shipborne sampling and numerical atmospheric chemistry modelling.
