Remote Antarctic island is 'richer in biodiversity than the Galapagos' Antarctica's remote South Georgia Island boasts 90 percent of the world's fur seals, half of the world's elephant seals, is navigated by vast populations of blue whales, sperm whales and killer whales, and has beaches that can be packed shoulder-to-shoulder with nesting penguins. In total, it contains nearly 1,500 recorded species, many of which are found nowhere else on Earth. It's difficult to believe that until recently, this biological treasure was believed to be nothing more than an "inhospitable lump of rock." In fact, researchers now believe that South Georgia Island contains more species than anywhere else in the Southern Ocean, and may be the most biologically diverse remote island in the world — even more diverse than the storied Galapagos Islands, according to the Independent. "It shows you don't have to be a tropical island or in a hot part of the world to support a lot of marine life. The types of marine life around the island vary immensely.

- Technology Ambri’s liquid metal battery technology is distinct from other storage options on the market today. Each cell consists of three self-separating liquid layers — two metals and a salt — that float on top of each other based on density differences and immiscibility. The system operates at elevated temperature maintained by self-heating during charging and discharging. The result is a low-cost and efficient storage system. Low Cost Ambri achieves low cost through the use of inexpensive, earth-abundant materials and a design that can take advantage of the economies of scale inherent to electro-metallurgy and conventional manufacturing. Flexible In the world of electricity storage, the liquid metal battery technology performs like both a tractor and a race car. Long Lifespan Liquid electrodes offer a robust alternative to solid electrodes, avoiding common failure mechanisms of conventional batteries, such as electrode particle cracking.

List of cognitive biases Systematic patterns of deviation from norm or rationality in judgment Cognitive biases are systematic patterns of deviation from norm and/or rationality in judgment. They are often studied in psychology, sociology and behavioral economics.[1] Although the reality of most of these biases is confirmed by reproducible research,[2][3] there are often controversies about how to classify these biases or how to explain them.[4] Several theoretical causes are known for some cognitive biases, which provides a classification of biases by their common generative mechanism (such as noisy information-processing[5]). Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior.

How twitching frog legs and salt work Whether it's a bright blue poison dart frog or a brown, warty toad, a frog's survival is all about water. Most frogs begin their lives as jelly-like eggs that need moisture to develop. The eggs hatch into aquatic tadpoles, which breathe through gills. As the tadpoles grow, they develop lungs and gain the ability to breathe air. But frogs' need for water doesn't dry up once they're on land. Frogs get virtually all of their water and part of their oxygen through their skin, and this process only works if their skin stays moist. So it should come as no surprise that frogs have developed some interesting adaptations to cope with their lifelong need for water. But frogs' adaptations aren't all about water or reproduction.

Genetically modified food Genetically modified foods (or GM foods) are foods produced from organisms that have had specific changes introduced into their DNA using the methods of genetic engineering. These techniques have allowed for the introduction of new crop traits as well as a far greater control over a food's genetic structure than previously afforded by methods such as selective breeding and mutation breeding.[1] Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its Flavr Savr delayed ripening tomato.[2] To date, most genetic modification of foods have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton seed oil. History The use of food biotechnology dates back to thousands of years ago to the time of the Sumerians and Babylonians. Food science and food biotechnology was then progressed to include the discovery of enzymes and their role in fermentation and digestion of foods. Method of production Fruits and vegetables
