Liquid air technology could boost the role of renewable energy

Liquid air technologies could help Britain tackle some of its toughest energy challenges, says a new report launched at Parliament today. The report, "Liquid Air Technologies – a guide to the potential," shows how liquid air could help balance an electricity grid increasingly dominated by intermittent renewables; provide strategic energy storage to keep the lights on; sharply reduce CO2 and tail-pipe emissions from vehicles; and convert low grade waste heat into usable energy throughout the economy.

Pattern of light from early universe detected by NASA

Does light leave tracks? How is it possible for scientists to observe light that originated billions of years ago? These are questions that intrigue us and we are amazed when scientists figure out a way to observe what to most of us is un-observable. The journey of light from the very early universe to modern telescopes is long and winding. The ancient light traveled billions of years to reach us, and along the way, its path was distorted by the pull of matter, leading to a twisted light pattern. This twisted pattern of light, called B-modes, has at last been detected. The discovery, which will lead to better maps of matter across our universe, was made using the National Science Foundation's South Pole Telescope, with help from the Herschel space observatory.

Red Smog alert chokes northern China

A red alert has been issued for several cities in northern China including Changchun and Harbin. A red alert is the highest level on the four-tiered alert system and is defined as serious air pollution for three consecutive days. According to Xinhuanet News, "the density of PM 2.5 -- airborne particles measuring less than 2.5 microns in diameter, exceeded 500 micrograms per cubic meter on Monday morning." Visibility is presently less than 50 meters in the downtown capital city of Harbin of Heilongjiang Province.

Park Your Electric Truck on a Manhole Cover to Charge It

Wireless electric vehicle charging is beginning to trickle into the market, which adds an appealing convenience factor that conventional gas-powered cars just can’t match. Meanwhile, consolidation in the retail gas sector has resulted in a long-term decline in the number of gas stations, while the number of public, private, and workplace EV charging stations has been skyrocketing.

The Yeti: A hoax or an ancient polar bear species?

The purported Yeti, an ape-like creature that walks upright and roams the remote Himalayas, may in fact be an ancient polar bear species, according to new DNA research by Bryan Sykes with Oxford University. Sykes subjected two hairs from what locals say belonged to the elusive Yeti only to discover that the genetics matched a polar bear jawbone found in Svalbard, Norway dating from around 120,000 (though as recent as 40,000 years ago).

Four in five children are not ‘connected to nature’

The ground-breaking study, led by the RSPB, marks the first time that connectivity between children and nature has been studied in the UK. Following 3 years of research, the project concluded that only 21% of children between the ages of 8 and 12 were 'connected to nature' at a level which is considered to be both realistic and achievable for all young people. The report stems from growing concerns over the distinct lack of contact with and experience of nature among modern children, which some have argued is having a negative impact on their education, health and behaviour. In addition, this disconnection is viewed as being a very real threat to the future of UK wildlife.

Plants Absorb Carbon, Reduce Historical Warming

From providing habitat to food sources, to regulating water cycles, plants are the backbone of all life on Earth. What often goes unrecognized, but is equally as important are plants' roles as climate controllers. According to a new study conducted by researchers at Princeton University, Earth's leafy greens have significantly slowed the planet's warming by absorbing carbon in the form of CO2, a popular greenhouse gas, especially during the past 60 years. How much carbon are we talking about? Approximately 186 billion to 192 billion tons of carbon have been taken out of the atmosphere since the mid-20th century!

Suggestions for restaurants to reduce food waste

People care about food waste for all kinds of reasons, starting with moral issues such as global hunger, environmental reasons including carbon footprint (food waste decomposes in landfills into methane, a potent greenhouse gas), and even health concerns like obesity. Despite all the attention traditionally given to leftovers, food scraps, uneaten crusts of bread, our consumers seem to be especially concerned about food waste away from home, and they are willing to take steps to deal with it that have implications for restaurant branding and practices, particularly regarding portion control and choice of doggie bags.

30 Year-Old Dream Comes True With The Construction Of Israel’s Biggest Solar Power Plant

The earth revolves around the sun, and so does the green-tech industry. Some of the earliest pioneers of solar energy started in Israel 30 years ago with the company Luz. Luz went on to become Luz II, then BrightSource, which is now a US-based solar power company about to flip the switch on a massive 377-megawatt solar thermal farm in the California desert.

Lucky to Find a New Dragon Tree Species

The Dracaena kaweesakii, thought to bring luck to the Thai people who have them in their households, has recently been identified as a new species within the group Dracaena. These beautiful trees are often associated with Buddhist temples. Researchers led by Paul Wilken, of Kew Royal Botanical Gardens and Piyakaset Suksathan have identified the morphologically distinct element of the plant group from Thailand and Burma. An undifferentiated leaf sheath, the lack of a leaf blade central costa, free tepals and thickened filaments, characterizes the newly identified species.
