The latest analysis of data coming from NASA's Kepler telescope has revealed that nearly all the Sun-like stars in our galaxy appear to have planets orbiting them, and that at least 17 percent of them – about one in six – are hosting a planet the size of our own in close orbit. Because the Milky Way is estimated to contain some 100 billion stars, this means that our galaxy alone could have at least 17 billion Earth-sized planets, some of which may harbor the conditions for life.  Read More

Researchers have found an inexpensive and efficient catalyst that can produce hydrogen for...

Hydrogen has been hailed as the fuel of the future, but producing it cleanly using platinum as a catalyst is simply too costly to service the world's energy needs. On the flipside, producing hydrogen with fossil fuels not only releases CO2 as a byproduct, but is unsustainable, negating hydrogen's green potential. However, hydrogen may yet make good on its promise thanks to a group of scientists at the University of Cambridge.  Read More

Blood clots are one way in which the body heals itself after injuries on even the tiniest level. The process is fast, reliable and goes on every minute of the day without our being aware of it. Now, a team led by MIT assistant professor of materials science and engineering Alfredo Alexander-Katz is studying blood clots as a new model for producing self-healing materials.  Read More

The Big Internet Museum finishes up with Gangnam Style – currently anyway

The internet only became commercialized in 1995, but its genesis goes back to the late 1960s, more precisely October 29, 1969. That was the date when Robert William Tayor, a former NASA researcher working for the Pentagon’s Advanced Research Projects Agency (ARPA), launched the ARPAnet operational network, which is recognized as the precursor to what became the internet. ARPAnet provides the starting point for visitors to the recently launched The Big Internet Museum, a virtual venue for all things great and downright silly about the internet.  Read More

The compact radiation source developed by Kovaleski's team at the University of Missouri (...

While we’ve seen developments that could see T-ray spectrometers featuring in a future handheld tricorder-like device, good ol’ X-rays could also get a guernsey thanks to an engineering team from the University of Missouri. The team has invented an accelerator about the size of a stick of gum that can create X-rays and other forms of radiation, opening up the possibility of cheap and portable X-ray scanners.  Read More

Fireflies ... they’ve allowed us to image the bloodstream and they’ve inspired the creation of a light that could run on waste. Now, they’ve helped an international team of scientists get over 50 percent more light out of existing LED bulbs. The secret lies in the insects’ scales.  Read More

According to researchers at Newcastle University in the United Kingdom, the kilogram is very likely getting heavier. How can this be? Mainly because we’re talking about the definitive kilogram, the International Prototype Kilogram (IPK) kept at the International Bureau of Weights and Measures in Paris. But because this is the kilo against which all kilos are defined, in a theoretical sense at least, all kilograms will technically be heavier too.  Read More

Observations made with the Atacama Large Millimeter/Submillimeter Array (ALMA) in northern Chile, which is scheduled for completion this year, have solved a longstanding mystery in solar system formation. They showed how protoplanets forming around a young star can use their own gravitational pull to slingshot matter in the direction of their host star, fueling its growth.  Read More

Gizmag's top five astronomical targets for small telescopes (Photo: Shutterstock)

If you received a telescope for Christmas, or bought one for your kids, your adventures in amateur astronomy are just beginning. Astronomy is the art and science of actually looking at the heavens and even a small telescope will let you find a host of celestial wonders. So where do you begin? Here are our suggestions for five of the most rewarding and spectacular objects with which to start your adventure in amateur astronomy ... plus some important tips on using a telescope.  Read More

A 3D image of a rotavirus, constructed from data gathered using the new technique

Traditionally, in order to view tiny biological structures such as viruses, they must first be removed from their natural habitats and frozen. While this certainly keeps them still for the microscope, it greatly limits what we can learn about them – it’s comparable to an ichthyologist only being able to study dead fish in a lab, instead of observing live ones in the ocean. Now, however, researchers at the Virginia Tech Carilion Research Institute have devised a technique for observing live viruses in a liquid environment. It could have huge implications for the development of treatments for viral infections.  Read More
