Scanning electron micrograph of Escherichia coli

Using two different model organisms–the E. coli bacterium and the single-celled yeast–scientist have begun unraveling a puzzling behavior of many micro-organisms: the ability to “predict” a change in environmental conditions.

It has been assumed for most of the history of micro-biological science that such micro-organisms are purely “reflexive”; they simply respond and adapt to external stimuli (such as exposure to chemicals, heat stress, or drugs). But research over he past 2 years by two different scientific teams (a Princeton team lead by Saeed Tavazoie, and, a team from the Weizmann Institute in Israel) is shaking up present understanding and over-turning basic assumptions.

Move over Nature…the famed strength of a spider’s web silk now has some competition. Bio-mimicry and bio-materials–both emerging new sciences that seek to utilize and/or reproduce or modify natural biological materials and properties for commercial usage–has been seeing an explosion of research and experimentation of late. Recent bio-materials experiments with spider dragline silk (taken from an Araneus spider’s silk glands) have resulted in a bio-mimicked new material that is stronger than its natural version.

To make this new material, the scientists had to “infiltrate” the inner protein structure of the spider’s dragline, silk threads with a metal ion of zinc (Zn 2+). These experiments built on earlier analyses of the mandibles of leaf-cutter ants, locusts, and marine polychaetes (a type of large sea worm) that showed a strong relationship between accumulated Zinc, Aluminum and Titanium levels in these materials and their high tensile and hardness properties.  Previous attempts to incorporate such metals synthetically had proven to be too great a technological challenge.

Two Kenyan students have invented a device that allows bicycle riders to charge their phones as they pedal.

Deemed a “dynamo-powered smart charger”, the device should make it more economical for the 17.5 million Kenyans who use mobile phones to charge them. Even more impressive, the environmentally-friendly phone charger was originally built from scraps retrieved from a junkyard.

In a meeting with environment and energy ministers from other European countries yesterday, Sweden’s Minister of Environment, Andreas Carlgren, said that global economic problems should in no way slow movement to address climate change. Other leading European ministers agreed.

Economic problems today are in many ways a result of environmental missteps in the past. If we want a healthy economy in the future, we have to take the environment into account more than we have. The Swedish Minister of the Environment agrees and says that there should be no hesitation to combat climate change due to the current economic situation. Read the rest of this entry »

The EU is cutting electricity use equivalent to Sweden and Austria’s annual usage. In total, after previous ecodesign regulations, the savings will be greater than Italy’s total consumption by 2020.

The European Union (EU) agreed to cut carbon emissions by 20% by 2020 earlier this year. They stated: “The challenge is to spark a new industrial revolution that will deliver a low-energy economy, whilst making the energy we consume more secure.” In another move to spark this new industrial revolution, the European Commission added 4 new eco-design standards this week to the 5 they had previously set.

The four new eco-design measures will save as much electricity as Sweden and Austria use annually. Combined with the previous five measures, the electricity savings will be more than the total annual usage of Italy!

In a macabre When Life Deals You Lemons – Make Lemonade kind of news item: Researchers are considering that perhaps we could safely reuse radioactive land: to grow crops for biofuel.

Growing food is still too dangerous in southeastern Belarus because the region is still so contaminated by fallout from Chernobyl that crops grown there cannot safely be eaten by humans for hundreds of years, until the radioactive isotopes decay.

Yet 1.5 million mostly older people have not left, and some are in fact growing some grain on the contaminated land anyway. The radioactive material concentrates in roots and stalks, which they just plough back into the ground after harvesting. As a result; the soil is still almost as contaminated now as it was after the accident.

Things could not be much worse there than they are now and the Belarus government is open to new ideas. So when an Irish company had the idea of remediating the soil by planting a biofuel crop, Belarus was more open to the idea than you might imagine:

Plans were announced today that will bring the United States and China together in order to fight the issue of global climate change. Energy Secretary Steven Chu, Chinese Minister of Science Wan Gang, and Administrator of National Energy Administration Zhang Guo Bao announced plans to develop a U.S.-China Clean Energy Research Center, which will facilitate cooperative research and development of clean energy systems.

Move over Sydney Opera House, the city’s major drama company is all set to go green.

Two months ago, the Sydney Theatre Company (STC) embarked on a major program to transform The Wharf, its much-loved home on Sydney Harbour, into a unique demonstration of how buildings, even heritage-listed ones, can be made more sustainable. A whopping $1.2m (Australian dollars) was committed through the Australian government’s Green Precincts Fund, to assist the Company’s Greening The Wharf project.

A few days ago, the company announced that it will install a large capacity photo voltaic array as a key initiative of the program. The installation of the 2,000 solar panels will be erected on the roof of The Wharf of the Sydney Harbour-based company, along with energy saving measures, and will reduce STC’s power drawn from the grid by up to 70 per cent. It is the first renewable energy project of its kind by any major theater company. Read the rest of this entry »

On exhibit now at the Cooper Hewitt in New York City is Design for a Living World. The design show exhibits ten of the world’s leading designers commissioned by the Nature Conservancy to develop new uses for sustainably farmed and harvested materials. Each invention shares a special story about global design and conservation as well as the life-cycle of the materials used. Read the rest of this entry »

Citizen journalism, open government, status updates, community building, information sharing, crowdsourcing, and the election of a President.

Editor’s note: This is a guest post from Max Gladwell.

Our children will inherit a world profoundly changed by the combination of technology and humanity that is social media. They’ll take for granted that their voices can be heard and that a social movement can be launched from their laptop. They’ll take for granted that they are connected and interconnected with hundreds of millions of people at any given moment. And they’ll take for granted that a black man is or was President of the United States.

What’s most profound is that these represent parts of a greater whole. They represent a shift in power from centralized institutions and organizations to the People they represent. It is the evolution of democracy by way of technology, and we are all better for it.

For most of us, social media has changed our lives in some meaningful way. Collectively it is changing the world for good. Given the pace of innovation and adoption, change has become a constant. Every so often we find the need to stop and reflect on its most recent and noteworthy developments, hence the following list.

Please note this is not a top-10 list, nor are these listed in any particular order. It’s also incomplete. So we ask that you add to this conversation in the comments. If you’d like to Retweet this post or take the conversation to Twitter or FriendFeed, please use the hashtag #10Ways.
