How an Artificial Leaf Could Boost Solar Power

Nature is amazing. Take the humble leaf—it's capable of absorbing the sunlight and converting it into the chemical energy that fuels the growth of plants. Photosynthesis is one of the fundamental forces of life, and it's far superior to our technological efforts to harness sunlight. A photovoltaic solar panel can transform sunlight to electricity, but right now that power is difficult to store without expensive batteries, which limits the potential of solar energy. The sugars produced by photosynthesis, though, can be tapped by a plant for energy whenever it's needed. A solar cell that could mimic photosynthesis would be a game changer for alternative energy.

IT and Information Sharing Environments for Community Health Resilience

Information Technology (IT) and Information Sharing Environments (ISEs) are crucial to the evolution of community health resilience.  Most people working to improve community health resilience do not understand the nuances of Information Sharing Environments, and how the rapid shifts in IT, mobile devices, social media, cloud computing, peer to peer parallel processing, smart grids, and the linking of millions of people, mobile devices, computers, and sensors are creating a societal mind, which is transforming community health resilience and the health and human security of Americans.

Mexican Editor's Death Linked to Work with Social Media

By the CNN Wire Staff

September 28, 2011

      

Message reportedly found near the body blames social networks

MEXICO CITY (CNN) -- Amnesty International said Monday that a newspaper editor whose decapitated body was found over the weekend in the Mexican border town of Nuevo Laredo appears to have been targeted by a drug gang carrying out a reprisal for her work on social networks.

Though no investigation has yet been carried out, a message was found next to the body indicating that she was killed by members of organized crime "in retaliation for the information that the victim had distributed in social networks denouncing the activities of criminals in Nuevo Laredo," the human rights group said in a statement posted on its website.

The decapitated body of Maria Elizabeth Macias, the editor of Primera Hora, a daily newspaper based in Nuevo Laredo in the eastern state of Tamaulipas, was found Saturday morning.

A Way to Make Motor Fuel Out of Wood? Add Water

A Georgia company says it has overcome a major roadblock in turning agricultural waste into vehicle fuel and other useful chemicals by experimenting with a technology that treats the waste with compressed water heated to very high temperatures.

The company, Renmatix, plans to cut the ribbon on a research and development center on Tuesday in King of Prussia, Pa., near the heart of the nation’s chemical and refining industry, to complete development of the process. The goal is to accomplish something that has eluded a dozen companies in recent years despite big government inducements: to commercialize a technology for making use of cellulosic biomass, or wood chips, switchgrass and the nonedible parts of crops.

The Power of the 21st Century Librarian

Michael D. McDonald, Dr.P.H.

It can be argued that libraries have their origins in the swarm behavior of individuals and groups acquiring and sharing cultural artifacts (e.g, pictographs, books) as the fundamental repositories of knowledge within a community and the broader society.  Librarians have played a key role in the founding and differentiation of  America at its origins.  Thomas Jefferson and Benjamin Franklin, for example, played key roles in deepening and broadening the tradition of knowledge sharing within the early United States.

Robert Kuttner: Can Europe Be Spared Cascading Collapse?

The failure of the European authorities to arrest the speculative run on Greek bonds and the sense of inevitable wider collapse reminds me of the diplomatic failures that led to World War I.

In the summer of 1914, myopic bluffing by Europe's key leaders produced a catastrophe that nobody wanted. It began in Serbia, a small nationalistic province of a decaying Austro-Hungarian empire, but the conflagration soon spread to all of Europe like a chain of firecrackers. No leader was farsighted enough to grasp the wider common stakes and head off disaster. Each pursued only narrow self-interest.

Jeremy Rifkin: The Third Industrial Revolution: Toward a New Economic Paradigm

 

Our industrial civilization is at a crossroads. Oil and the other fossil fuel energies that make up the industrial way of life are sunsetting, and the technologies made from and propelled by these energies are antiquated. The entire industrial infrastructure built off of fossil fuels is aging and in disrepair. The result is that unemployment is rising to dangerous levels all over the world. Governments, businesses and consumers are awash in debt and living standards are plummeting everywhere. A record one billion human beings--nearly one seventh of the human race--face hunger and starvation.

'Wi-fi Refugees' Shelter in West Virginia Mountains

BBC News - September 12, 2011

       

Nichols Fox lives alone in a home powered primarily by gas just outside the Quiet Zone

Dozens of Americans who claim to have been made ill by wi-fi and mobile phones have flocked to the town of Green Bank, West Virginia

There are five billion mobile phone subscriptions worldwide and advances in wireless technology make it increasingly difficult to escape the influence of mobile devices. But while most Americans seem to embrace continuous connectivity, some believe it's making them physically ill.

Diane Schou is unable to hold back the tears as she describes how she once lived in a shielded cage to protect her from the electromagnetic radiation caused by waves from wireless communication.

"It's a horrible thing to have to be a prisoner," she says. "You become a technological leper because you can't be around people.

"It's not that you would be contagious to them - it's what they're carrying that is harmful to you."

Explosion at French Nuclear Waste Plant

An explosion at a French nuclear waste processing plant that killed one person and injured four others sparked fears of a radioactive leak on Monday.

An emergency safety cordon was thrown around the Marcoule nuclear site near Nimes in the south of France immediately after a furnace used to melt nuclear waste exploded and caused a fire. It was lifted later in the day after France's nuclear safety agency, the Autorité de Sûreté Nucléaire (ASN), said there was no danger to the public.

Reports said the body of one male worker at the plant had been "found carbonised", but there was no evidence that the explosion had caused any radioactive leak, though the ASN admitted there was the "possibility of a leak of low-level radioactivity, but no shooting of radioactivity in the air". There was no information as to the cause of the explosion.

The accident came just a week after the French president, Nicolas Sarkozy, bucked the anti-nuclear trend following Japan's Fukushima disaster and pledged €1bn (£860m) of new investment in atomic power.
