Perhaps Your Pennies Can Clear the Air

Apparently copper can be used to scrub pollutants out of the air. Maybe one day a penny can help clean your house.

An easy way to get carbon dioxide out of the atmosphere is to find a chemical that combines easily with it, similar to the way that some metals oxidize. For example, compounds involving copper will usually combine with oxygen in the atmosphere voluntarily without catalysts, covering the surface of the copper material with a green patina, like the Statue of Liberty.

Unlike oxygen, carbon dioxide cannot combine so easily with other materials. It is possible to remove one electron from the molecule to facilitate its integration into other molecules, but that removal requires an electric potential of -1.97 volts, which is unreasonably high for the purpose of processing a single molecule.

One group of scientists found a certain dinuclear copper (I) complex that turns green when exposed to air under a slight electric potential (-0.03 volts). At first, they assumed it was from the exposure to oxygen, but upon closer inspection they learned that this particular form of copper was reacting with carbon dioxide.

Wind Power Shelters Sea Life

You read that right: wind power generation can shelter sea life. Offshore wind farms help create spaces that encourage sea life to grow in a similar fashion to coral reefs.

Offshore wind power and wave energy foundations can increase local abundances of fish and crabs. The reef-like constructions also favour for example blue mussels and barnacles. What’s more, it is possible to increase or decrease the abundance of various species by altering the structural design of foundation. This was shown by Dan Wilhelmsson of the Department of Zoology, Stockholm University, in a recently published dissertation.

“Hard surfaces are often hard currency in the ocean, and these foundations can function as artificial reefs. Rock boulders are often placed around the structures to prevent erosion (scouring) around these, and this strengthens the reef function,” says Dan Wilhelmsson.

A 4-Day Work Week Works

Working full time can easily drain one’s life, so don’t do it. The state of Utah now has their government employees work only four days a week and everyone’s loving it. Perhaps during this time of economic recovery we can negotiate a better people-friendly work week for the labour force.

A whole series of unexpected benefits started to emerge. The number of sick days claimed by workers fell by 9 per cent. Air pollution fell, since people were spending 20 per cent less time in their cars. Some 17,000 tonnes of warming gases were kept out of the atmosphere. They have a new slogan in Utah – Thank God It’s Thursday.

But wouldn’t people be irritated that they couldn’t contact their state authorities on a Friday? Did the standard of service fall? It was a real worry when the programme started. But before, people had to take time off work to contact the authorities, since they were only open during work hours. Now they were open for an hour before work and an hour after it. It actually became easier to see them Monday to Thursday: waiting times for state services have fallen.

Think of it as the anti-Dolly Parton manifesto, puncturing her famous song: “Workin’ 9 to 5/ What a way to make a livin’/ Barely gettin’ by/ Its enough to drive you/ Crazy if you let it…” A queue of US cities and corporations like General Motors are following suit, and Britain’s councils and companies should be sweeping in behind them. It’s a win-win-win – good for employees, good for employers and good for the environment.

And once we started on this course, it could spur us to think in more radical ways about work. If this tiny little tinker with work routines leads to a big burst of human happiness and environmental sanity, what could bigger changes achieve?

People in the UK Love Recycling

Some research that was released late last year found that people in the UK really like caring for the environment with recycling being the most popular green practice.

Green behaviours costing the least money and effort are currently the most popular with the British public, despite the fact that 59 per cent of people think that if things continue on their current course we will soon experience a major environmental disaster.

A fuller picture of environmental and other behaviours and attitudes based on the first annual survey of 100,000 individuals from 40,000 households for Understanding Society will be published at a later date.

Self Control is Like the Flu: It’s Contagious

I know it’s strange to say that self control is contagious: but it is, so you should catch it by having friends that are good practitioners of self control.

“The take home message of this study is that picking social influences that are positive can improve your self-control,” said lead author Michelle vanDellen, a visiting assistant professor in the UGA department of psychology. “And by exhibiting self-control, you’re helping others around you do the same.”

People tend to mimic the behavior of those around them, and characteristics such as smoking, drug use and obesity tend to spread through social networks. But vanDellen�s study is thought to be the first to show that self-control is contagious across behaviors. That means that thinking about someone who exercises self-control by regularly exercising, for example, can make your more likely to stick with your financial goals, career goals or anything else that takes self-control on your part.

VanDellen’s findings, which are published in the early online edition of the journal Personality and Social Psychology Bulletin, are the result of five separate studies conducted over two years with study co-author Rick Hoyle at Duke University.

In the first study, the researchers randomly assigned 36 volunteers to think about a friend with either good or bad self-control. Those that thought about a friend with good self-control persisted longer on a handgrip task commonly used to measure self-control, while the opposite held true for those who were asked to think about a friend with bad self-control.
