Fresh Water From Power Plants
A new system developed by MIT engineers could provide a low-cost source of drinking water and simultaneously reduce power plant operating costs.
Oman’s Rocks
There is growing interest in the idea of capturing and storing carbon dioxide. Reducing the amount of it we are putting into the atmosphere is essential for limiting the effects of climate change, but even eliminating emissions entirely is not enough because the CO2 already there stays in the atmosphere for decades or more.
Protecting Reefs Of Hope
One of the most harmful effects of the changing climate is what is happening to coral reefs. Warmer ocean temperatures and acidification are causing widespread bleaching of coral. Stressed corals expel the algae living in their tissue, turning the corals white and robbing them of nutrients. When bleaching events persist, the corals starve and die. Reefs everywhere have been experiencing mass bleaching events in recent years with over 70% of the coral reefs around the world being damaged.
An Accidental Plastic Eater
A couple of years ago, scientists in Japan discovered bacteria at a recycling plant that were breaking down a type of plastic called polyethylene terephthalate, or PET. With the world facing a growing plastic pollution problem, British and American researchers began to study the enzyme that the bacteria were using to try to understand how it works.
Climate Change And Biodiversity
According to a new study recently published in the journal Climatic Change, up to half of the plant and animal species in the world’s most naturally-rich areas could face local extinction by the turn of the century due to climate change. This projection, jeopardizing the biodiversity in places like the Amazon and the Galapagos, assumes carbon emissions continue to rise unchecked.
Accidentally Saving The Bees
There is no shortage of dangers to honey bees, but a parasitic mite known as Verroa destructor is considered to be the greatest threat because it transmits virus diseases which lead to colony death.
Elephant Tourism
Elephant tourism is an activity through which tourists can observe and interact with the stately mammals. A quick online search reveals all sorts of elephant pictures and selfies – patting, washing, riding, and the like. But this popularity comes at a great cost to elephants.
Solving Terrible Traffic
Terrible traffic in cities around the world is a real blight on urban life. Increasingly, there are many cities where you simply don’t want to have to go anywhere by car during morning and evening rush hours.
Air Pollution And Solar Power
We are well-aware of the negative effects of air pollution on human health and on the environment, but a recent study at Duke University has revealed that global solar energy production is taking a major hit due to air pollution and dust.
Antarctica Is Getting Greener
The frozen landscape of Antarctica is getting greener. Researchers drilling into layers of moss that have been accumulating in Antarctica over the last 150 years have found that the growth rate of the moss has been speeding up over the past 50 years.
Carbon Dioxide Marches On
The end of 2013 marked the first occasional observations of carbon dioxide levels in the atmosphere of 400 parts per million. There is nothing magical about that value, but we do tend to focus on round numbers.
Spray-On Solar Cells
One of the most exciting possibilities for future solar energy technology is that of solar cells that can be sprayed or printed on to surfaces like the windows of skyscrapers, the roofs of sports utility vehicles, or the walls of houses. And the expectation is that such technology would be far cheaper than today’s silicon-based solar panels.
Squeaking By
Amphibians are one of the most threatened groups of animals on the planet. Since the late 1980s, scientists have measured dramatic population declines from locations all over the world. The plummeting amphibian populations are perceived to be one of the most critical threats to global biodiversity. According to the IUCN, about 1 of every 3 amphibian species is facing extinction. Some of the greatest threats facing amphibians include climate change, disease, and habitat destruction.
The Largest Battery Storage Substation
At the end of last year, Southern California Edison turned on the largest lithium-ion battery storage facility in the world in Ontario, California. It is a substation with 80 megawatt-hours of capacity, enough energy to power 2,500 households or charge 1,000 Tesla cars a day.
Why Do Animals Eat Ocean Plastic?
It’s no secret that there is a lot of plastic debris in our oceans. In fact, scientists estimate that there is more than 165 million tons of plastic trash swirling about in our oceans today, with an additional 8.8 million tons flowing in every year. And as the oceans swell with plastic litter, hundreds of marine species are ingesting the stuff – often with dire consequences.
