Simulations shows magnetic field can change 10 times faster than previously thought

(University of Leeds) A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth’s magnetic field may take place 10 times faster than previously thought.

Stop making sense: why it’s time to get emotional about climate change | Rebecca Huntley

It took me much longer than it should have to realise that educating people about climate change science was not enough. Due perhaps to my personality type (highly rational, don’t talk to me about horoscopes, please) and my background (the…

Twenty-year study tracks a sparrow song that went ‘viral

With the help of citizen scientists, researchers have tracked how one rare sparrow song went ”viral” across Canada, traveling over 3,000 kilometers between 2000 and 2019 and wiping out a historic song ending. The study reports that white-throated sparrows from British Columbia to Ontario have ditched their traditional three-note-ending song in favor of a unique two-note-ending variant — although researchers don’t know what made the new song so compelling.

Why are the offspring of older mothers less fit to live long and prosper?

(Marine Biological Laboratory) In a new study in rotifers (microscopic invertebrates), scientists tested the evolutionary fitness of older-mother offspring in several real and simulated environments, including laboratory culture, under threat of predation in the wild, or with reduced food supply. They confirmed that this effect of older maternal age, called maternal effect senescence, does reduce evolutionary fitness of the offspring in all environments, primarily through reduced fertility during their peak reproductive period. They also suggest an evolutionary mechanism for why this may occur.

Rising water temperatures could endanger the mating of many fish species

(Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research) In a new meta-study, experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have published ground-breaking findings on the effects of climate change for fish stock around the globe.

Higher concentration of metal in Moon’s craters provides new insights to its origin

There has been considerable debate over how the Moon was formed. The popular hypothesis contends that the Moon was formed by a Mars-sized body colliding with Earth’s upper crust which is poor in metals. But new research suggests the Moon’s subsurface is more metal-rich than previously thought, providing new insights that could challenge our understanding of that process.
