March 22nd (tomorrow) is World Water day.
From the United Nations website, “World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.
An international day to celebrate freshwater was recommended at the 1992 United Nations Conference on Environment and Development (UNCED). The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day.”

Smithsonian News — “The water in Lake Vida has been cut off from its surroundings for roughly 2,800 years, nowhere near the 15 million for Lake Vostok or other Antarctic subglacial lakes. But, the fact that things are alive in Lake Vida at all further extends the idea that where there is water, there is life.”
From Nature News about an article in Science.
Misfolded protein transmits Parkinson’s from cell to cell—Link between cell death and protein clumps opens pathway to possible treatment.
A team led by Virginia Lee, a neurobiologist at the University of Pennsylvania in Philadelphia, injected a misfolded synthetic version of the protein α-synuclein into the brains of normal mice and saw the key characteristics of Parkinson’s disease develop and progressively worsen. The study, published today in Science, suggests that the disease is spread from one nerve cell to another by the malformed protein, rather than arising spontaneously in the cells.

Have you ever wondered how a Lord Howe Island stick insect’s spindly body unfurls from a tiny egg as it hatches? Yea. Me too. All the time. Now I know.
Good video on the importance of the theory of evolution within science. “This video was produced to allow scientists to explain, in their own words, the importance of evolution to science — and the related importance of teaching evolution in schools.” Found the video through the post at the Scientific American and the #sciencegirlthing Twitter hashtag.
“Researchers have discovered how very large whales co-ordinate their jaw muscles and bones to take gigantic mouthfuls of prey.” The full paper at Nature is here, subscription probably required.
Now you know.
“The swallows will still come back to Capistrano, albatrosses will wing their way across vast oceans, and homing pigeons will still arrive at home. But scientists are no longer sure how they do it.” From the Chronicle of Higher Ed.
