Over the past few years I've had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn't going-so far as I can tell-but it's changing. I'm not thinking the way I used to think. I can feel it most strongly when I'm reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I'd spend hours strolling through long stretches of prose. That's rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I'm always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle. I think I know what's going on. For more than a decade now, I've been spending a lot of time online, searching and surfing and sometimes adding to the great databases of the Internet. The Web has been a godsend to me as a writer. Research that once required days in the stacks or periodical rooms of libraries can now be done in minutes. A few Google searches, some quick clicks on hyperlinks, and I've got the telltale fact or pithy quote I was after. Even when I'm not working, I'm as likely as not to be foraging in the Web's info-thickets'reading and writing e-mails, scanning headlines and blog posts, watching videos and listening to podcasts, or just tripping from link to link to link. (Unlike footnotes, to which they're sometimes likened, hyperlinks don't merely point to related works; they propel you toward them.)

The world in which we live would hardly be recognised by someone who lived and died half a century ago and who may have caught a glimpse of the television generation. The children born in the 90′s have only known a world where the Internet was a natural part of  their day to day lives. We now live in a society that verges on a digital tipping point that wraps and integrates our lives with the Web and it is no longer considered a luxury but a necessity in our modern lifestyle. So what is driving us to this digital dawn that is transporting us from the industrial past of the last 200 years and the TV industrial complex that emerged 50 years ago and embracing us in an information age that challenges our paradigms?

Policymakers are very familiar with land-use planning. But what is the best approach for planning uses of America's coastal waters and oceans? That question has gained importance since President Obama formed the National Ocean Council last summer and charged it with developing an ecosystem-based stewardship policy for the nation's oceans, coastal waters and the Great Lakes.

A survey by the National Association of Realtors conducted in March 2011 revealed that 62 percent of people ages 18-29 said they would prefer to live in a communities with a mix of single family homes, condos and apartments, nearby retail shops, restaurants, cafes and bars, as well as workplaces, libraries, and schools served by public transportation.  A separate 2011 Urban Land Institute survey found that nearly two-thirds of 18 to 32-year-olds polled preferred to live in walkable communities. Younger Americans are also using technology to substitute for driving, connecting with friends and family online, substituting Facebook, Twitter, Skype, or FaceTime interactions for in-person visits and using online shopping and e-commerce in place of driving to and from grocery and retail stores, the report notes. For generations of Americans, car ownership was an almost mandatory rite of passage-a symbol of freedom and independence. For more and more young people today, a car is a burden they no longer wish to carry. 

A new study from Forrester proves that the majority of Americans are a bunch of lazy re-tweeters. Ninety-three percent of online consumers in emerging markets of China, India, Mexico and Brazil use social media tools at least once-a-month. U.S. and European consumers are far more likely to use social media as a spectator-like sport, joining it and then just watching it fly by. In the U.S., 68% of social media users are joiners, which means they maintain a profile on a social networking site and visit social networks. Only 73% are spectators, or users who mostly just read blogs, online forums, customer ratings/reviews and tweets, listen to podcasts and watch videos. This number is strikingly similar in Europe (EU-7 countries, to be specific), with 69% of users classified as spectators and 50% as joiners.

Those making land use decisions to reduce the harmful effects of climate change have focused almost exclusively on greenhouse gases - analyzing, for example, how much carbon dioxide is released when a forest is cleared to grow crops. A new study in Nature Climate Change aims to present a more complete picture - to incorporate other characteristics of ecosystems that also influence climate.

UC Berkeley physicist Richard Muller and others were looking at the so-called urban heat island effect - the notion that because more urban temperature stations are included in global temperature data sets than are rural ones, the global average temperature was being skewed upward because these sites tend to retain more heat. Hence, global warming trends are exaggerated. Using data from such urban heat islands as Tokyo, they hypothesized, could introduce "a severe warming bias in global averages using urban stations." In fact, the data trend was "opposite in sign to that expected if the urban heat island effect was adding anomalous warming to the record. The small size, and its negative sign, supports the key conclusion of prior groups that urban warming does not unduly bias estimates of recent global temperature change."

The invention of a long-lasting incandescent light bulb in the 19th century spurred on the second wave of the industrial revolution, illuminating homes, extending leisure time and bringing us to the point today where many millions of people use a whole range of devices from mood lighting to audiovisual media centers, microwave ovens to fast-freeze ice makers, and allergy-reducing vacuum cleaners to high-speed broadband connected computers in their homes without a second thought.

Plastic may compete with paper in the grocery line, but it doesn't have to compete with the world's food supply, according to University of Florida researchers. They've developed a way to produce plastic that doesn't use valuable natural resources, such as food or fuel, for raw materials. The new method uses a strain of bacteria to create bioplastic from discarded plant material, such as yard waste.

Given water's role in power generation, the impact of about 300 million Google searches a day is around 150,000 litres (40,000 gallons) daily -- in a world where water supplies are increasingly a major concern. "These two things -- water and energy -- come together and that's a big thing for the world to understand," says Len Rodman, a US-based water and energy expert. "If you squander water, if you indiscriminately use power, then in the long run that will have implications for the world," the chief executive of Black & Veatch, a major global water and energy company told AFP in an interview.

Many energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn. They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.

The website titled "Visualizing Our Future Selves"[news21.com] attempts to answer the question how the dramatically aging demographics in the US will change over the next 40 years. It is an example of a 'personalized' visualization of sorts, in that users are asked to submit their personal demographic data, such as birth year, race, state, living situation and gender. The resulting diagrams then reveals country-wide statistical information in the context of one's own situation, divided into 4 different groups: Population, State, Health and Finances. Accordingly, the application shows an animated population pyramid, a population age density map of the US, a disease (e.g. cancer, heart disease, diabetes) prevalence forecast, and an income versus expenditure comparison filtered by several demographic variables.

The idea of a "digital divide" -- describing those who can or cannot get on the Internet -- has been around since the 1990s. Although, it used to refer mostly to access, now it often also means the quality and speed of Internet access -- and the skills to make use of the technology.

Imagine a cell phone battery that charges with every step you take or a spacesuit that uses astronauts' expended energy to run the suit's electronics. A team of college students conducting NASA research on this innovative use of nanotechnology took their research to new heights. The team, comprising Hannah Clevenson, Olivia Lenz and Tanya Miracle, flew an experiment related to their nanotechnology research on a NASA reduced-gravity flight.

Scientists at the NRL Materials Science and Technology Division are providing solid evidence that there is a new route towards developing novel, lightweight energy storage devices. By moving away from centuries of caustic, hazardous aqueous-based battery cells and instead using non-volatile, thermally-stable ionic liquids, scientists predict multiple new types of batteries. Rather than depend on highly acidic electrolytes, ionic liquids are used to create a solid polymer electrolyte composed of an ionic liquid and polyvinyl alcohol, developing novel types of solid state batteries with discharge voltages ranging up to 1.8 volts.

Mediterranean landscapes have undergone great change in recent decades, but species have adapted to this, at least in the case of roe deer, Spanish ibex, red deer and wild boar. This has been shown by Spanish researchers who have analysed the effects of changes in land use on the past, present and future distribution of these species.

Your next new car hopefully won't be a lemon. But it could be a pineapple or a banana. That's because scientists in Brazil have developed a more effective way to use fibers from these and other plants in a new generation of automotive plastics that are stronger, lighter, and more eco-friendly than plastics now in use. They described the work, which could lead to stronger, lighter, and more sustainable materials for cars and other products, here today at the 241st National Meeting & Exposition of the American Chemical Society (ACS).

With billions of pounds of meat and bone meal going to waste in landfills after a government ban on its use in cattle feed, scientists today described development of a process for using that so-called meat and bone meal to make partially biodegradable plastic that does not require raw materials made from oil or natural gas. They reported here today at the 241st National Meeting and Exposition of the American Chemical Society (ACS).

Containers made from plastics are used in most traditional greenhouse operations. While plastic containers are practical, strong, and can be formed to any size, shape, or color, the extensive use of these petroleum-based containers creates significant waste disposal problems for the greenhouse industry and consumers. One example: a 2008 report found that a typical greenhouse operation in California discards over 3560 pounds of plastic trays, flats, and containers annually.

US President Barack Obama said Saturday that a transition to cleaner energy will help create more American jobs as he promoted his new initiative designed to reduce US energy imports by a third.
