The Kepler spacecraft could still hunt planets using gravity miscrolensing ( Image: NASA)

Last month, NASA declared its Kepler mission to hunt exoplanets at an end when one of the space telescope’s reaction wheels failed. Unable to keep itself pointed in the right direction, it could no longer carry on its hunt for planets beyond the Solar System. That seemed like the end of things, but Keith Horne of the University of St Andrews and Andrew Gould of Ohio State University disagree. They claim that Kepler could still hunt for exoplanets using gravity microlensing to detect how stars with planets distort space.  Read More

It can’t be easy, being a lifeguard at a pool full of children. The kids that catch your attention are going to be the ones who are splashing and yelling, whereas the ones that you really need to look for could be silently slipping below the surface, where they won’t be seen or heard. North Carolina-based emergency physician Graham Snyder decided that those potential drowning victims needed more attention drawn to their predicament, so he created the Seal system.  Read More

According to a joint World Health Organization/UNICEF report issued this week, an estimated 768 million people relied on unimproved drinking-water sources in 2011, with 185 million of these relying on surface water to meet their daily drinking-water needs. WHO and UNICEF have set a 2030 target for everyone to have access to a safe drinking-water supply and new water-purifying “nanoscavengers” developed by researchers at Stanford University could help achieve this goal.  Read More

The NDūR Survival Straw filters out nasties from dirty water as you drink

Most of us take water for granted. If we want a drink, we turn a tap or twist a cap and there it is. But if you find yourself off the beaten track in triple-digit heat without it, locating some can mean the difference between life and death. Finding a pool of water in the shade of a rock may seem like a godsend, but then the question of waterborne diseases raises its head. That’s where the NDūR Survival Straw comes in.  Read More

That’s just what San Diego inventor Hal Slater claims to have done with the creation of a water heater system that promises to improve water heating efficiency by as much as 50 to 100 percent.  Read More

PureMadi project leaders James Smith and Dr. Rebecca Dillingham

Silver is known for its antibacterial qualities, and has thus found its way into water filters created at institutions such as Stanford and McGill universities. Given that these filters are often used in developing nations, however, it would be nice if they could also contribute to the local economy – instead of being just one more thing that’s brought in from outside. Well, that’s just the idea behind the University of Virginia’s PureMadi filters and MadiDrops.  Read More
