Climate change caused mangrove collapse in Oman
Most of the mangrove forests on the coasts of Oman disappeared about 6,000 years ago. Until now, the reason for this was not entirely clear. A current study now sheds light on this: It indicates that the collapse of coastal ecosystems was caused by climatic changes. The results are published in the journal Quaternary Research. (2021-01-05)

Deep, slow-slip action may direct largest earthquakes and their tsunamis
Megathrust earthquakes and subsequent tsunamis that originate in subduction zones like Cascadia -- Vancouver Island, Canada, to northern California -- are some of the most severe natural disasters in the world. Now a team of geoscientists thinks the key to understanding some of these destructive events may lie in the deep, gradual slow-slip behaviors beneath the subduction zones. This information might help in planning for future earthquakes in the area. (2020-12-21)

Hawai'i researchers kept the data flowing during crisis response on K?lauea
The summer 2018 eruption of K?lauea Volcano on the Island of Hawai'i was one of the most significant in the volcano's history, collapsing a large portion of the summit caldera, erupting massively from its flank and triggering a magnitude 6.9 earthquake in the process. Through it all, scientists at the Hawaiian Volcano Observatory were installing new geophysical stations, processing data and making real-time reports to local authorities and neighborhoods.

Dynamics in the root zone
Nutrient contamination of groundwater as a result of nitrogen-based fertilisers is a problem in many places in Europe. Calculations by a team of scientists led by the UFZ have shown that over a period of at least four months per year, nitrate can leach into the groundwater and surface water on about three-quarters of Europe's agricultural land. The proportion of areas at risk from nitrate leaching is thus almost twice as large as previously assumed. (2020-12-09)

Trace amine-associated receptor 5 (TAAR5) to rewire your brain naturally
Researchers have found a new role for recently discovered neurotransmitter system that uses the trace amine-associated receptor 5 (TAAR5) for neurotransmission. It has been observed that lack of TAAR5 in mice leads to a higher number of dopamine neurons and an increase in adult neurogenesis, i.e. the process by which new neurons are formed in the brain. (2020-11-10)

Infection by parasites disturbs flight behaviour in shoals of fish
Shoal behaviour in fish is an important strategy for them to safeguard their survival. Certain parasites are able to manipulate this strategy. Biologists have discovered that infected individual fish disturb the transmission of flight behaviour and, as a result, increase not only their own risk of being eaten, but also that of other - non-infected - members of the group. (2020-11-09)
