The announcement that was accompanied by the release of a time-lapse video showing infrared footage of the gas leakage coming to a complete halt was made on February 11, by Dennis Arriola, CEO of the Southern California Gas Company (SoCal Gas)....

Just like Harry Potter's invisibility cloak, Marty Mcfly's hoverboard, featured in "Back to the Future" Part II and III, has captured the imagination of both fans and scientists. But despite numerous claims, no one has been able to replicate the flying skateboard that bounced off walls and easily outpaced cars. Now thanks to US-based ARCA Space Corporation, hoverboards may finally become a reality....

Snakes are amongst the most feared animals in the world. The sight of the slithering reptiles can send even the bravest human or animal scampering for safety.

Athletes and sports fans hoping to attend the 2016 Summer Olympics in Rio de Janeiro, Brazil this August may be faced with a terrible dilemma. They will have to decide if a quest for a medal or the opportunity to cheer their favorite athlete is worth the potential health risk posed by the Zika virus that has been plaguing Brazil since April 2015....

With the increasing popularity of drones as toys and potentially even for commercial delivery, researchers are going all out to build cooler and more sophisticated quadcopters. However, none can compare to the Loon Copter, which not only flies like a bird, but also swims like a fish!...

Palm oil is the most widely consumed vegetable oil in the world. It is found in a wide variety of products ranging from vitamins to chocolate, bread, laundry detergent and even biofuel. The oil is popular because it has an exceptionally high melting point and contains primarily saturated fats. The former allows the oil to maintain a semi-solid consistency at room temperature making it easy to spread, while the latter makes it the perfect substitute for trans fats which are generally deemed unhealthy. It also has the highest yield of any oil crop and is cheap to produce and refine....

All our lives, we have been repeatedly warned by our elders to avoid excessive social contact for fear of contracting harmful germs and bacteria. Turns out that it may not be all bad. A recently released study suggests that interaction with others also helps in the acquisition of good bacteria - At least in chimpanzees....

In mid-January, scientists from University of Cambridge's Department of Zoology released some heart-breaking news for Spider-Man fans. The researchers said that the web-slinging hero could never exist in real-life. And it is not due to the lack of radioactive spiders, but because humans are simply too big to skitter up tall buildings....

King Kong fans will be pleased to hear that the massive skyscraper climbing ape is not just a figment of filmmakers' imagination. There were actual giant apes or Gigantopithecus that roamed the planet not too long ago. However, since the only fossil evidence found is the lower jawbone and a handful of teeth, researchers have been unable to glean much insight into the giant ape's lifestyle or what caused it to become extinct....

Access to electricity has always been sketchy for the 173 residents of Nuevo Saposoa, a remote village in Peru. S.America. However, things went from bad to worse in March 2015 after a flood damaged the few power cables in the area. The villagers were forced to turn to kerosene lamps, which are not only expensive but also dangerous because of the toxic fumes they emit....

When humans began Space exploration about 55 years ago, they had no intention of leaving behind equipment that had served its purpose. It could after all, easily fall to Earth and harm innocent people. But that fear subsided in 1964 when American research satellite Vanguard 1 continued to rotate in orbit even after it had lost all contact with ground scientists. Since then researchers have become increasingly comfortable about leaving trash behind....

Australia is home to some of the world's deadliest animals. However, few are as dangerous as the cane toad. Native to Central and South America, the innocent looking amphibian is an invasive species that was imported to Australia in 1935 to control the native grey-backed cane beetles that were harming sugarcane crops. With very few natural predators, their population began to grow rapidly. Experts estimate that there are currently over 200 million specimens spread across Northern Australia and the numbers are only growing....

Remember ROY.G. BIV (red, orange, yellow, green, blue, indigo, violet), the mnemonic that helped you to memorize the order and colors of the rainbow? Well, you can forget it because as it turns out, not all rainbows are equal. They can vary drastically depending on the conditions under which they occur. A team led by atmospheric scientist Jean Ricard of the National Centre for Meteorological Research in Toulouse, France, has identified twelve rainbow 'flavors', each with its own distinct characteristics....

When Pluto was demoted to dwarf status in 2006 we were left with a mere eight planets in our solar system. Now Planetary Astronomy Professor Mike Brown, the researcher responsible for 'killing' Pluto may have redeemed himself with the discovery of a massive ninth planet - One he believes is worthy of being added to the elite group of eight....

Thanks to strict regulations imposed by the US Environmental and Protection Agency, clean tap water is something Americans take for granted. But such is not the case for the residents of Flint, Michigan. Their water supply is so tainted that President Obama declared a federal state of emergency in Flint releasing up to $5 million USD to help the city combat what is probably one of the biggest public health crisis of recent times....

On December 30, the International Union of Pure and Applied Chemistry announced that elements 113, 115, 117 and 118 are now approved to join the prestigious periodic table. Their addition completes the group of man-made elements that make up the table's 7th row, and brings the total number that will need to be memorized by students to 118!...

Food waste is a growing problem both in the United States and across the globe. In North America alone anywhere from 30-40% of perfectly edible food ends up in the trash each year. To put it in perspective that is almost 20 pounds of food per person, per month! While the fact that most ends up in our landfills is bad enough, what's worse is that over 48 million Americans, including 15.3 million kids, live in households that do not have sufficient food! Now, concerned citizens are trying to raise awareness of the issue with some innovative ideas....

Time and again we hear about alliances between animals that would ordinarily be prey and predator. But in most cases they are a result of a strategic decision made by zoo keepers trying to help one or both animals. However, that was not the intention of the workers at Russia's Safari Park when they allowed a goat into their resident Siberian tiger Amur's enclosure in November 2015. They were just serving him dinner! Hence, you can only imagine how surprised they were to find the goat alive and well the following day....

It is the beginning of a new year. This means that most of us have a lengthy list of goals laid out for the next 365 days. Facebook's founder Mark Zuckerberg is no exception. While his past resolutions have been mundane challenges like reading two books a month, meeting a new person every day of the year and mastering Mandarin, this year the Internet mogul has a loftier goal. He wants to build his own version of Tony Stark's (AKA Iron Man's) digital assistant and closest friend, Jarvis (Just A Rather Very Intelligent System)....

The 2015 holiday season brought little cheer to the thousands of Southern California residents affected by a methane leak from an underground gas storage facility. Since late November, over 2,800 families from the Porter Ranch Community in Los Angeles have been forced to flee their homes to escape the adverse effects of the odorless gas. What's worse is that they have no idea when they will be able to return....

A few years ago, Douglas Long and his colleagues from the California Academy of Sciences were helping D. Ross Robertson identify some chimaeras caught off the Pacific coast of Central America in 2010. Among the images were those of a mysterious pitch black shark. Intrigued, the marine ichthyologist asked the Smithsonian Institute researcher to lend him the preserved specimens so that his team could study the fish in detail....

Access to clean water is something many of us take for granted. However, for millions of people living in developing nations, it is a scarce commodity. According to the World Health Organization 3.4 million people, mostly children, die annually from water-related diseases. But that could change soon thanks to 'Row-bot', a tiny autonomous robot that powers itself by eating harmful water microbes....
