Boiling water makes for cooler electronics

Boiling water seems a straightforward enough exercise, you flick on the gas and wait for the bubbles to start popping. But by manipulating how many of those bubbles appear as the temperature rises, scientists have discovered a new way to finely control how much heat and steam is released in the process, a technique they say could lead to advanced cooling systems for more efficient electronic devices.

Buoys warn swimmers of dirty water

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.Read More

Bizarre fourth state of water discovered

You already know that water can have three states of matter: solid, liquid and gas. But scientists at the Oak Ridge National Lab (ORNL) have discovered that when it's put under extreme pressure in small spaces, the life-giving liquid can exhibit a strange fourth state known as tunneling.Read More

Is Asia's water supply in trouble?

Based on a series of simulations ran through sophisticated computer models, researchers from MIT are highlighting the possibility that a significant percentage of the population of Asia could suffer severe water shortages by the year 2050. As a basis for the study, the team made use of a pre-existing MIT-generated computer model designed to simulate Asia's complex economic, climate, and growth characteristics. A detailed water-use model known as a Water Resource System was then introduced, and the team ran a number of simulations aiming to cover the widest range of potential scenarios.Read More

Dawn continues to unravel Ceres' secrets

Dawn's science team has presented a treasure trove of data and images captured by the spacecraft as it orbits a mere 240 miles (385 km) above the surface of the dwarf planet Ceres. The observations, which include a stunningly detailed view of the famous Occator crater, are leading to a series of breakthroughs regarding the nature of the enigmatic wanderer including the first detection of ice water on the planetoid's surface.Read More

Portable Hotaru shower applies pressure on the road

Portable showers, like this car-mounted version, have been around for some time, but they have a couple of disadvantages. First, their reservoir tanks can only hold a limited amount of water. Second, the pressure in most portable showers tends to be pretty feeble, as they usually rely on gravity for water flow. The Hotaru shower exhibited this week at SXSW tackles both problems, providing plenty of water pressure and reusing the same water for weeks at a time.Read More

SteriPen's UVR tech amplifies UV rays to speed up water purification

There are many ways to filter and purify water out in the wild, the MSR Guardian and Oasis being a couple of the most recent we've looked at. Since 1999, Hydro-Photon has gone with ultraviolet light, offering lightweight, compact SteriPen purifiers that quickly zap away microorganisms. With its new Ultraviolet Reflection (UVR) technology, it makes the UV purification process even faster, so outdoor enthusiasts can get clean water more efficiently than ever. Read More
