Researchers... have developed a new drug that can be delivered directly into the eye via an eye dropper to shrink down and dissolve cataracts - the leading cause of blindness in humans.Publication in Nature. Discussion at Reddit.
The new drug is based on a naturally-occurring steroid called lanosterol. The idea to test the effectiveness of lanosterol on cataracts came to the researchers when they became aware of two children in China who had inherited a congenital form of cataract, which had never affected their parents. The researchers discovered that these siblings shared a mutation that stopped the production of lanosterol, which their parents lacked...
They tested their lanosterol-based eye drops in three types of experiments. They worked with human lens in the lab and saw a decrease in cataract size. They then tested the effects on rabbits, and according to Hanae Armitage at Science Mag, after six days, all but two of their 13 [rabbits] had gone from having severe cataracts to mild cataracts or no cataracts at all. Finally, they tested the eye drops on dogs with naturally occurring cataracts. Just like the human lens in the lab and the rabbits, the dogs responded positively to the drug, with severe cataracts shrinking away to nothing, or almost nothing.
Sam Caress and Jordan Pellett recently adopted Gunner. He's helped fill the hole in their hearts created when Luna, their two-year-old dog, died in April after getting into some chewing gum made with the sugar-substitute Xylitol.More at CBS News; video at the link.
Xylitol is safe for humans but can cause severe low blood sugar, seizures -- even liver failure -- in dogs.
Sugar-free gum is the biggest culprit. But Xylitol is also used in some sugar-free candies, chewable vitamins, even some baked goods and peanut butter.
The number of products is on the rise and so are the calls to the ASPCA's Animal Poison Control Center, from 82 in 2004 to more than 3,700 last year.
"For the first time in their lives two dozen recently rescued ducks get their first taste of life in a pond. They had been living for years with a hoarder who had them in pens without adequate access to water or proper nutrition."Backstory at Woodstock Farm Sanctuary.
Ecuador is home to the tallest mangroves in the world: The Cayapas Mataje Reserve. Its soil is filled with small black cockles — a culinary delicacy prized in Ecuador — and the arduous task of searching for and picking those shelled creatures from the mangroves falls on the shoulders of children, who use their long limbs and agile bodies to scale the spindly branches of the trees and mine the thick mud that surrounds them.My thoughts drifted to vague memories of reports of warfare conducted in such ecosystems and the pure hell that soldiers in combat must have endured. I had thought I remembered battles in mangrove swamps in the U.S. Civil War, but for the moment the only reference I can find is to the Battle of Ramree Island in the South Pacific:
"That night [of the 19 February 1945] was the most horrible that any member of the M.L. [motor launch] crews ever experienced. The scattered rifle shots in the pitch black swamp punctured by the screams of wounded men crushed in the jaws of huge reptiles, and the blurred worrying sound of spinning crocodiles made a cacophony of hell that has rarely been duplicated on earth. At dawn the vultures arrived to clean up what the crocodiles had left. . . . Of about one thousand Japanese soldiers that entered the swamps of Ramree, only about twenty were found alive.Some years ago I tried to hike through a tamarack swamp in northern Minnesota; the footing was treacherous and unpleasant, but presumably a log power easier than this mangrove tangle. The other images in the photoessay give some insight into a life different from the ones you and I live.

"As it turns out, some octopuses, like this one, possess the foresight to actually pack along coconut shells to use as protective shelters when exploring areas without adequate places to hide."
