A Useful New Brew Tester: brewPal

Brewing goes high-tech. Well at least it does for small breweries. There is nothing worse than gulping down a cool stubbie and getting a flat, foul tasting experience. This seldom happens, of course, due to testing of the product in its creation.

Invisible Sentinel has made a fantastic new product that solves most of the problems. A tiny device like a pregnancy tester called brewPal fits comfortably into your hand.  It analyses a beer's DNA and shows only one of two findings: either the beer is clear, or it has a spoiling infection.

When you exercise, lactic acid builds up in your body. This makes you feel tired. Excess lactic acid is also the cause of "off" beer. Unwanted bacteria produce the acid. Lactobacillus and Pediococcus are resistant to hops so they thrive in the brew. Oddly, some beers need these bacteria.

Culturing beer in the lab was time-consuming, especially in the hunt for Lactos and Pedis. It takes a week. Small companies can now test their beer with brewPal at the time of bottling to ensure a quality product. At last a company makes something really useful!

Natural History Museum Human Evolution Gallery

 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...

Study of Tooth Enamel Indicates Neanderthal Diet Was Carnivorous

 A new study on Neanderthal dietary practices has just been published in the journal PNAS by researchers from the French National Centre for Scientific Research (CNRS) and several German scientific institutions. They were able to determine that a Neanderthal who lived in a cave on the Iberian Peninsula during the Middle Paleolithic period (50,000 years ago) ate exclusively carnivorous food using a newly developed method for studying the chemical signatures of ancient tooth enamel. This isn't the first study to find this, either. Despite this, it is a one-of-a-kind and significant discovery because it was made through the development of a novel analytical method that could be used to learn more about the diet and way of life of Neanderthals who lived in other parts of Eurasia in the distant past.   To investigate the diet and eating habits of Neanderthals, numerous research projects have been initiated. However, they have resulted in contradictory outcomes. The CNRS researchers...
