Norman Conquest of 1066 did little to change people’s eating habits

Archaeologists have combined the latest scientific methods to offer new insights into life during the Norman Conquest of England. Until now, the story of the Conquest has primarily been told from evidence of the elite classes of the time. But little has been known about how it affected everyday people’s lives.

Hot Summer Mess: New Climate Models Exaggerate Midwest Warming By 6X

For the last 10 years, I have consulted for grain growing interests, providing information about past and potential future trends in growing season weather that might impact crop yields. Their primary interest is the U.S. corn belt, particularly the 12…

More ecosystem engineers create stability, preventing extinctions

(Santa Fe Institute) Biological builders like beavers, elephants, and shipworms re-engineer their environments. How this affects their ecological network is the subject of new research, which finds that increasing the number of “ecosystem engineers” stabilizes the entire network against extinctions.

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.

Microscope allows gentle, continuous imaging of light-sensitive corals

Many corals are sensitive to bright light, so capturing their dynamics with traditional microscopes is a challenge. To work around their photosensitivity, researchers developed a custom light-sheet microscope (the L-SPI) that allows gentle, non-invasive observation of corals and their polyps in detail over eight continuous hours, at high resolution.
