Mysterious bio-duck sound attributed to the Antarctic minke whale (Balaenoptera bonaerensis

Source: Royal Society Biology Letters

For decades, the bio-duck sound has been recorded in the Southern Ocean, but the animal producing it has remained a mystery. Heard mainly during austral winter in the Southern Ocean, this ubiquitous sound has been recorded in Antarctic waters and contemporaneously off the Australian west coast. Here, we present conclusive evidence that the bio-duck sound is produced by Antarctic minke whales (Balaenoptera bonaerensis). We analysed data from multi-sensor acoustic recording tags that included intense bio-duck sounds as well as singular downsweeps that have previously been attributed to this species. This finding allows the interpretation of a wealth of long-term acoustic recordings for this previously acoustically concealed species, which will improve our understanding of the distribution, abundance and behaviour of Antarctic minke whales. This is critical information for a species that inhabits a difficult to access sea-ice environment that is changing rapidly in some regions and has been the subject of contentious lethal sampling efforts and ongoing international legal action.

How to Drink All Night Without Getting Drunk

Jim Koch knows beer. He also knows a beer trick that may change your life.

... co-founder and chairman of the Boston Beer Company, ... Jim Koch...
Joseph Owades was a flat-out genius. With a PhD in biochemistry ... and an early job in the fermentation sciences department at Fleischmann’s...
... Owades knew ... that active dry yeast has an enzyme in it called alcohol dehydrogenases (ADH) ... if you also have that enzyme in your stomach when the alcohol first hits it, the ADH will begin breaking it down before it gets into your bloodstream and, thus, your brain. 

“And it will mitigate – not eliminate – but mitigate the effects of alcohol!” Koch told me.

In his final years Owades even patented a product called Prequel, an all-natural pill similarly designed to limit drunkenness. No companies wanted to deal with the potential liabilities of the product, and Owades died in 2005 at the age of 86.
