The SteriPEN Freedom is a USB-rechargeable portable UV water purifier

Water purifier manufacturer SteriPEN has updated its lineup of portable products, with a UV-based unit called the SteriPEN Freedom. Billed as the smallest, lightest and first rechargeable UV water purifier on the market, it disinfects up to 16 oz (0.5 L) of water in 48 seconds.  Read More

The winners of the US$1.4 million Wendy Schmidt Oil Cleanup X CHALLENGE were announced tod...

Last July, in the aftermath of the Deepwater Horizon oil spill, the X PRIZE Foundation launched the Wendy Schmidt Oil Cleanup X CHALLENGE. As with previous X PRIZE competitions, this one was intended to encourage private sector scientific research, by offering a cash prize to whichever team could best meet a given challenge. In this case, teams had to demonstrate a system of their own making, that could recover oil from a sea water surface at the highest Oil Recovery Rate (ORR) above 2,500 US gallons (9,463.5 liters) per minute, with an Oil Recovery Efficiency (ORE) of greater than 70 percent. Today, the winning teams were announced.  Read More

While you may feel quite virtuous when you leave all your glass containers out for recycling, you might be surprised to know that much of your colored glass won’t be used. That’s because even though there’s a fairly constant demand for recycled clear glass, glass in colors such as green, brown and blue isn’t all that sought-after, so many recycling centers don’t bother processing it. As a result, waste colored glass is now being stock-piled in some locations, waiting for a use. Thanks to research conducted at the University of Greenwich, however, that glass may soon be used for filtering pollutants out of ground water.  Read More

Dr. Shane Snyder is working with Agilent to develop ways to detect emerging contaminants  ...

Agilent Technologies has announced it will begin collaborations with the University of Arizona's Department of Chemical and Environmental Engineering's BIO5 Institute to develop ways to detect and treat "emerging contaminants" such as steroids and antibiotics in drinking water.  Read More

Artist's concept illustrating a quasar, or feeding black hole, similar to APM 08279 5255, ...

Two international teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The researchers found the huge mass of water feeding a black hole, called a quasar, more than 12 billion light-years away. The mass of water vapor is at least 140 trillion times that of all the water in the world's oceans combined and 100,000 times more massive than the sun.  Read More

Atlantis may have taken off on the last ever space shuttle mission last week but that doesn’t mean it has finished racking up firsts. Along with ferrying its last batch of supplies to the International Space Station (ISS), Atlantis is also carrying a urine recycling system that is designed to convert astronaut’s urine into a sports drink. The Forward Osmosis Bag (FOB) system will reportedly be tested by one of the four-man crew towards the end of the shuttle’s 12-day mission.  Read More

Although it may have missed the entry deadline for the Wendy Schmidt Oil Cleanup X-CHALLENGE, a new technology for containing oil spills at sea was recently unveiled. Developed by Norwegian research organization SINTEF, the system uses a curtain of air bubbles to contain spilled oil for easier removal, or to form a barrier around protected areas.  Read More

A scientist has proposed that ships could move through the ocean with less friction, if th...

Want to make a ship move faster through the water? Well, one thing that you can do is paint its hull with low-friction or anti-biofouling paint, to keep barnacles and other marine organisms from growing on it. According to Prof. Derek Chan, from the University of Melbourne's Department of Mathematics and Statistics, another approach that should work is to heat that hull up to a temperature of over 100C (212F). His proposed method is based on a 255 year-old principle known as the Leidenfrost effect.  Read More

Koseq's Victory Oil Sweeper is one of ten technologies competing in the Wendy Schmidt Oil ...

If there was one thing that last year's Gulf of Mexico oil spill showed us, it was that there were no particularly good systems in place for containing and removing such spills while the oil is still out at sea. One year later, although many companies and individuals have come forward with their concepts for such systems, little has actually been developed to the point of being ready for deployment. In order to generate some incentive, and provide financial support to the cream of the crop, the X PRIZE Foundation is now in the midst of its US$1.4 million Wendy Schmidt Oil Cleanup X CHALLENGE. Although the competition has been under way since January, the ten finalist teams were announced just last week.  Read More

Given that approximately one sixth of the world's population lacks access to safe drinking water, it would obviously be a very good idea to create something that allows those people to easily and cheaply filter their local tainted water. That was the thinking behind the LifeStraw. Developed by European disease control firm Vestergaard Frandsen, the simple device allows individual users to drink directly out of unclean water bodies, without ingesting pathogens or other pollutants. Now, the larger-scale LifeStraw Family is being introduced in Kenya, where it could potentially save millions of lives, reduce air pollution, and pay for itself in the process.  Read More
