Consumption of lungworm snails can transmit the lungworm parasite Angiostrongylus cantonensis
, which can cause meningitis
in humans and respiratory problems in dogs, which can eat afflicted slugs while running through open fields. Researchers at the University of Exeter hooked up LEDs to these snails
to study their nighttime movements through gardens and how those movements might help them act as a vector for the parasites.

"During the most recent ice age, milk was essentially a toxin to adults because — unlike children — they could not produce the lactase enzyme required to break down lactose, the main sugar in milk. But as farming started to replace hunting and gathering in the Middle East around 11,000 years ago, cattle herders learned how to reduce lactose in dairy products to tolerable levels by fermenting milk to make cheese or yogurt. Several thousand years later, a genetic mutation spread through Europe that gave people the ability to produce lactase — and drink milk — throughout their lives. That adaptation opened up a rich new source of nutrition that could have sustained communities when harvests failed." - The Milk Revolution - how a single mutation expanded (some) of humanity's diet.

The disease that sours oranges and leaves them half green, already ravaging citrus crops across the world, had reached the state’s storied groves. To slow the spread of the bacterium that causes the scourge, they chopped down hundreds of thousands of infected trees and sprayed an expanding array of pesticides on the winged insect that carries it. But the contagion could not be contained.
With a precipitous decline in Florida’s harvest predicted within the decade, the only chance left to save it, Mr. Kress believed, was one that his industry and others had long avoided for fear of consumer rejection.
They would have to alter the orange’s DNA — with a gene from a different species

on September 22 last year, Professor Robert Fuller
of the University of North Georgia spent four months paddling down the Chattahoochee River system, from the Chattahoochee's headwaters in northern Georgia down through the Apalachicola into the Gulf of Mexico, studying water quality
along the way. Then he paddled 200 miles through the Gulf, turned at the mouth of the Mobile River, and paddled another 750 miles upstream
on the Mobile, Alabama, Coosa, and Etowah Rivers all the way back
to northern Georgia—a total of just over 1,500 miles of solo paddling in his Kruger Sea Wind
. Along the way, he kept a blog
, "ate a lot of Beanie Weenies"
, and faced difficulties including cold, hunger, injuries, and river obstructions. Incidentally, he did all this while living with leukemia

"During his days as Harvard’s influential president, Dr. Charles W. Eliot made a frequent assertion: If you were to spend just 15 minutes a day reading the right books, a quantity that could fit on a five-foot shelf, you could give yourself a proper liberal education. Publisher P. F. Collier and Son
loved the idea and asked Eliot to compile and edit the right collection of works. The result: a 51-volume series of classic works from world literature published in 1909 called Dr. Eliot’s Five Foot Shelf
, which would later be called The Harvard Classics
