Is the water in your local lake clean enough to swim in today? Currently, the only way to find out is for someone to take a water sample, bring it back to a lab, then report the analysis 24 to 48 hours later. Soon, however, water-sampling buoys anchored off of beaches could provide readings in real time.

Let’s Go into Water: Tips for Pool Training
The whole world waiting for the Olympic Games in Rio de Janeiro, and water sports will be one of the most spectacular. Instead of just sitting at the TV in the middle of summer, why not to set a personal record and not to get in good form? If you have already decided to join the pool, read carefully our recommendations, and your workouts will become much more productive.
How to choose a swimming pool?
Since we take the example of Olympians, and our goal is a serious workout, it is better to delete from the list relaxation options like water parks and bathing complexes.
Low-cost water purifiers use chip packets to kill off dangerous bacteria
Armed with plywood, a glass tube and some empty chip packets, mechanical engineering students from the University of Adelaide have developed a low-cost water purification system capable of killing off harmful bacteria. The solution is designed for remote communities in Papua New Guinea (PNG), an area where water is particularly susceptible to pathogen infestation.
New type of rechargeable battery – just add water
Scientists at Stanford have developed a battery that uses nanotechnology to create electricity from the difference in salt content between fresh water and sea water. The researchers hope to use the technology to create power plants where fresh-water rivers flow into the ocean. The new “mixing entropy” battery alternately immerses its electrodes in river water and sea water to produce the electrical power.
FATS bulletproof life vest self-inflates when it hits the water
Bulletproof vests are great if you happen to get shot, but what happens if you get shot on a boat and fall overboard or have to dive into choppy waters to escape a fire? Well, hopefully you’re wearing the Flotation Armor Torso System (FATS) from BCB International. Not only does this vest protect you from bullets, it self-inflates to serve as a life vest.
The newly updated FATS vest isn’t the first inflatable bulletproof vest on the market, but it offers a clean, multipurpose design that protects both the wearer and self-inflating lifesaver with NIJ 0101.06 IIIA-standard armor. It includes front and rear MOLLE attachments and enough buoyancy to float the person wearing the vest and all their equipment. Read more
