Chemists create rewritable paper

Researchers have created an alternative to paper by using heat sensitive dyes in cellulose embedded in plastic. The new paper could reduce the environmental impact of paper. First developed in China in about the year AD 150, paper has many uses, the most common being for writing and printing upon. Indeed, the development and spread of civilisation owes much to paper's use as writing material. According to some surveys, 90 per cent of all information in businesses today is retained on paper, even though the bulk of this printed paper is discarded after just one-time use. Read More

Get the IT edge : In a crowded technology market, IT professionals need to stand out and here's how you can do just that…

Ahmedabad Mirror | 5 Dec 2014

For more than two decades, the Indian IT industry has moved at an astonishing rate. India already has nearly 2.75 million software developers, according to recent estimates, and by 2018, this is expected to be over five million. The outcome of this influx is that many technology skills that once were hard to find are now available in abundance. Also, advances in technology are happening at an accelerated rate, thus rapidly pushing existing technology skills and capabilities into obsolescence. Read More

Life's first spark recreated in a lab

Ahmedabad Mirror | 10 Dec 2014

Researchers have used a laser, clay and chemical soup to successfully recreate the building blocks of life. Giving credibility to the theory that life on Earth might have begun after a an asteroid struck the planet. Scientists in a lab used a powerful laser to re-create what might have been the original spark of life on Earth. Researchers zapped clay and a chemical soup with the laser to simulate the energy of a speeding asteroid smashing into the planet. They ended up creating what can be considered crucial pieces of the building blocks of life. Read More

Microwaves can turn muck into aluminium

Ahmedabad Mirror | 09 Dec 2014

Researchers have devised a way to use microwaves to turn aluminium-laminated plastic waste into aluminium for smelting and hydrocarbons for fuel in just three minutes. It started with a bacon roll and a microwave oven, and now it’s poised to transform the recycling of a packaging material that has been as unrecyclable as it is useful. The bacon roll, as the story goes, was microwaved for so long it turned into a charred mass of carbon that began to glow red-hot. What was happening was an intense heating process called microwave-induced pyrolysis. Read More

Computers to use light instead of wires for data

Ahmedabad Mirror | 09 Dec 2014

Stanford engineers have inched closer to developing faster and more efficient computers that use light instead of wires to carry data. Researchers have designed and built a prism-like device that can split a beam of light into different colours and bend the light at right angles. The development could eventually lead to computers that use optics, rather than electricity, to carry data. Read More

Device tests for HIV sans electricity

Ahmedabad Mirror | 06 Dec 2014

Researchers have created an HIV test that uses a chemical reaction instead of electricity. Rural docs can also use device to check for malaria and TB. Diagnosing HIV and other infectious diseases presents unique challenges in remote locations that lack electric power, refrigeration, and appropriately trained health care staff. Read More

New technique could harvest more of the sun's energy

As solar panels become less expensive and capable of generating more power, solar energy is becoming a more commercially viable alternative source of electricity. However, the photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped. A new technology represents a first step toward harnessing that lost energy. Read More

Warmer Pacific Ocean could release millions of tons of seafloor methane

Water off Washington's coast is warming a third of a mile down, where seafloor methane shifts from a frozen solid to a gas. Calculations suggest ocean warming is already releasing significant methane offshore of Alaska to Northern California. Read More

Computers that teach by example

New computer system enables pattern-recognition systems to convey what they learn to humans. Computers are good at identifying patterns in huge data sets. Humans, by contrast, are good at inferring patterns from just a few examples. Researchers have developed a new system that bridges these two ways of processing information, so that humans and computers can collaborate to make better decisions. Read More

New technique allows low-cost creation of 3-D nanostructures

Wetlands more vulnerable to invasives as climate changes

Changing water temperatures, rainfall patterns and seasonal river flows linked to global warming may give invasive wetland plants a slight but significant competitive edge over less adaptable native species, according to a groundbreaking three-year field study conducted at 24 riparian wetland sites in the US Southeast.

Abandoned wells can be 'super-emitters' of greenhouse gas

Researchers have uncovered a previously unknown, and possibly substantial, source of the greenhouse gas methane to the Earth's atmosphere. After testing a sample of abandoned oil and natural gas wells in northwestern Pennsylvania, the researchers found that many of the old wells leaked substantial quantities of methane. Because there are many abandoned wells nationwide, the researchers believe the overall contribution of leaking wells could be significant. Read More

Roll-to-roll process improves viability of spray on solar cells

Researchers in Canada believe they’ve made a significant advance toward making spray-on solar cells easier and more economical to manufacture. Illan Kramer and colleagues at the University of Toronto said they have made the breakthrough by devising a new way to spray solar cells onto flexible surfaces using miniscule, light-sensitive colloidal quantum dots (CQDs).

Harnessing the Power of Gravity

The New York City Department of Environmental Protection (DEP) will build a new hydroelectric facility at the city’s Cannonsville Reservoir, located in Delaware County. By capturing the natural force of the billions of gallons of water that are released from Cannonsville Reservoir each year, the hydroelectric facility will generate enough electricity to power roughly 6,000 homes and it will avoid the emission of 25,620 metric tons of greenhouse gases each year — the equivalent of removing 5,400 automobiles from the road. The facility is also expected to generate approximately $2 million in revenue each year, depending on demand and the market price of electricity. Read More

A Climate of Change In Flood Risk Management

The late Gilbert F. White, known worldwide as the father of floodplain management, declared in his doctoral dissertation, “Floods are acts of God, but flood losses are largely acts of man.” That was in 1942.

Plastic legacy

The issue of how to deal with a growing amount of waste plastic is exercising one UK company. The abundant usefulness of plastic is tempered by the legacy it leaves when humans have no more use for it. The material endures because it is durable, lightweight and low cost; factors that go some way to explaining how global production has increased from 1.5 million tonnes per year in 1950 to 245 million tonnes in 2008.
