Biologist warn of early stages of Earth’s sixth mass extinction event | ScienceDaily

The planet’s current biodiversity, the product of 3.5 billion years of evolutionary trial and error, is the highest in the history of life. But it may be reaching a tipping point. Scientists caution that the loss and decline of animals is contributing to what appears to be the early days of the planet’s sixth mass biological extinction event. Since 1500, more than 320 terrestrial vertebrates have become extinct. Populations of the remaining species show a 25 percent average decline in abundance. The situation is similarly dire for invertebrate animal life.

DrinkPure water filter shows promise for worldwide use
-
It’s no secret that hundreds of millions of people around the world have little or no access to drinkable water. While a number of projects are aimed at getting filtration systems to those people, many of those systems require electricity, contain costly materials such as silver, or treat the water at a slow rate. The low-cost DrinkPure filter, by contrast, is simply screwed onto the top of an existing bottle, and can purify approximately one liter (34 fl oz) of water per minute. DrinkPure was conceived by Jeremy Nussbaumer, a student at the ETH Zurich research institute. Working with a team led by ETH’s Wendelin Stark, he’s created a prototype which weighs just 100 grams (3.5 oz) and that can reportedly meet the hydration needs of one person for up to a year, before needing its filtration media replaced. Users simply fill a regular plastic bottle with untreated water, screw the filter onto the neck of that bottle, and then squeeze the bottle to force the water through. Filtration is carried out via a three-step process. A pre-filter starts by capturing large particles such as sand and plant matter. The water then passes through a layer of activated charcoal, that helps remove odors and chemical contaminants. Finally, a proprietary polymer membrane removes bacteria. This polymer was previously developed by two other students, and contains tiny pores that allow water molecules to pass through, while blocking the passage of microbes. Additionally, the filter as a whole is said to be less expensive and easier to manufacture than most conventional filters. While commercial availability of DrinkPure for people such as hikers is a possibility down the road, Nussbaumer first and foremost wants to see it used in humanitarian aid. To that end, he has recently launched an Indiegogo campaign, to fund field testing of the device in Africa. A pledge of US$89 will get you a filter of your own, assuming the funding goal is met.

24-year-old photographer Asher Svidensky recently traveled to west Mongolia with the intention of documenting the lives of traditional Kazakh eagle hunters, people who tame eagles for the purpose of hunting smaller animals.

With the traditions typically laying in the hands of the boys and the men, the biggest surprise throughout the journey was Svidensky’s discovery of a young eagle huntress, 13-year-old Ashol Pan, the daughter of an experienced eagle hunter. These stunning photographs symbolize the potential future of the eagle hunting tradition as it expands beyond a male-only practice.
