Solar powered traffic light conceptualized in China
Image source: ecofriend.org
The advent of solar panels gave way to several innovative ideas on how to utilize solar energy for contemporary use. Chinese designers Cheng-Tsung Feng, Yao-Chieh Lin and Bo-Jin Wang have conceptualized a solar-powered traffic light. Instead of the usual three-tiered design, they proposed a single unit that will switch from red to amber then green with the use of light-emitting diodes or LED technology and its power source would be from solar panels attached to its hood. The idea seems quite practical considering that most traffic lights are already exposed to the heat of the sun during daytime. Read the full article here

Think locally, act globally? – More on the psychology of climate change
A recent study by the American Psychological Association suggests that humans adopt a herd mentality when it comes to our behavior regarding the environment. Apparently fitting in is more important to us than doing the right thing or sometimes even surviving – at least when the threat is not immediate or is perceived as abstract. A herd mentality can be seen as a survival instinct – in humans as well as the animal kingdom. The Sydney Morning Herald reports the findings...
Another environmental conundrum: Emissions vs. conservation or high-speed rail vs. air travel
A lot of conservation seems to be about 'spoiling nice views' rather than more pragmatic ecological or environmental concerns. More specifically, grass roots political opposition to energy or transportation infrastructure projects that also have environmental aims often stems from such projects' potential to spoil rich peoples' nice views. For example, the opposition to wind turbines in wealthy, picturesque parts of American states like Cape Cod in Massachusetts, or in various country retreats in the U.K. is rarely related to practical...
The Wildlife Trade in Southeast Asia – A Wanton Waste of Beauty?
The habitats of Southeast Asia – its dense jungles, teeming oceans and twisting rivers -- are full of wildlife. But so are its network of airport hubs, transit depots and border crossings. The former is expected in the rich and lush environment of the tropics; the latter points to the enormous wildlife trade that runs rampant and most times afoul of the law. Whether continuing to follow age-old practices of centuries past or finding new wild delicacies and trends to indulge...
Spreading the word about climate change and its health impacts
I deeply admire documentaries that talk about the perils of climate change and its impacts on our environment, health, personal and social lives, occupation, and almost everything that deals with our existence as humans. I was not initially impressed by the emergence of issues on global warming, but after some “coercion” from my former colleagues to watch “An Inconvenient Truth,” I finally gave in. I have not always been the here-I-am-and-listen-to-me-or-else-activist, but I have to admit that the impacts of...
Warming oceans: Species return to Atlantic after 800,000 years
Arctic ice melt due to warming temperatures is causing marine plankton to migrate from the Pacific Ocean to the Atlantic via Arctic waters. This may have huge consequences for marine ecosystems of which plankton form the basis. An EU-funded study, the CLAMER project, discovered that a species of phytoplankton called Neodenticula seminae has returned to the Atlantic Ocean, where it has not lived for 800,000 years. And it’s not just algae. Warming ocean temperatures are also causing animal plankton to migrate into...
Does summer time reduce energy consumption?
Since 2007, daylight saving time (DST) in the United States starts nearly 3 weeks earlier than in previous years. It now begins on the second Sunday of March, while Europe begins European Summer Time (EST) on the last Sunday of March. But why do we do 'spring forward' and does it have any real benefits, such as saving energy? Below are two video reports from msnbc.com that offer differing opinions on the subject. According to the United States Department of Energy, daylight saving...
A Bird’s Eye View: Chickens See Colors Better Than You
Chickens are enjoyed the world over, both as pets and as tasty meals. Beyond food, companionship, religious purposes or entertainment, not much is really thought of these flightless birds. Even though we may be higher than them on the food chain, they do have us beat in one area, at least: color vision. Compared to the human eye, chickens have superior color vision, which can be contributed to a structurally well-organized eye. Researchers conducted a study that mapped 5 types of...
The Song of the Blue Whale: Mysterious, Deep, and Ever-changing
Blue Whales don’t sing like they used to. Their voices become increasingly deeper by the year—and scientists don’t know why. The male blue whale is the only one that sings, so one theory is the younger males are trying to emulate the sounds of older, larger blue whales for the sake of mating purposes. It could easily be compared to the way human males try to (unsuccessfully) make their voices sound lower in order to impress a woman. Whale Acoustics president, Mark...
You Otter Get Involved With Sea Otter Awareness Week
This week marks the annual Sea Otter Awareness Week, started and sponsored by the Defenders of Wildlife organization. Sea Otters are listed as an endangered species, which makes this particular week very important. During this week, there are a lot of events taking place that will teach people about the otters, promote research and conservation, and have a number of activities involved. Most of these events are in the US, such as the Sea Otter Awareness Celebration in Pittsburgh, games...
Space news: Oceans on Mars, the apocalypse from above and no more men on the Moon
Scientists at the university of Colorado have discovered evidence that suggests that much of Mars was once covered by ocean. From an article by Australia's ABC News: To test their theory Dr Hynek and Mr Di Achille used global databases of known deltaic deposits and valley networks, together with topography data from a laser altimeter aboard NASA's Mars Observer spacecraft which is orbiting the red planet. If Mars had that much water 3.5 billion years ago, what happened to it? And did it...
