African nations to phase out lead in paint by 2020
December 16, 2015 07:26 AM - Ochieng Ogodo, SciDevNet
African countries have agreed to cooperate in setting limits for use of lead in paints with a view to phasing it out by 2020. This is because of its dangers to human beings, especially to children, and the environment.
Top 10 Renewable Energy Producing States
December 14, 2015 07:17 AM - Gina-Marie Cheeseman , Triple Pundit
The U.S. has a chance to be a leader in renewable energy deployment given its sheer size and resources. And some states are leading the way. Olivet Nazarene University’s engineering department ranked the top 10 green states in terms of renewable energy. How does your state stack up? Did it make the list? Read on to find out.
Epson paper-recycling printer coming soon
December 14, 2015 06:42 AM - Leon Kaye , Triple Pundit
Printing boarding passes is sooooo 2005. Seriously, does anyone still print? My handy HP all-in-one printer collects more dust than print jobs. While it is true that most paper comes from managed forests, most of us just do not really have the need to print — a trend the paper industry, including the Paper and Packaging Board, whines about endlessly.
But sometimes we do need to print — for example, editing is easier for me to do on paper than staring at that laptop screen. And as an office tactic, distributing handouts at a meeting is a way to keep those rude colleagues’ eyes on the whiteboard and hands off their smartphones.
From Toilet to Tap

The rainfall and snowpack so far this autumn have been encouraging, but the stubborn reality is that California is still mired in drought. While farmers from Bakersfield to Fresno to Redding are screaming about water quotas, California residents say they are doing what they can, from pulling out grass lawns to capturing what little rainwater exists.
Global food system faces threats from climate change
December 4, 2015 07:14 AM - UCAR
Climate change is likely to have far-reaching impacts on food security throughout the world, especially for the poor and those living in tropical regions, according to a new international report that includes three co-authors from the National Center for Atmospheric Research (NCAR).
Fixing Food Deserts
December 1, 2015 07:30 AM - Joi Sears, Triple Pundit
Food deserts, vast expanses of urban and rural areas that are void of fresh fruit and veggies, are a growing epidemic — affecting more than 23.5 million people nationwide. Disproportionately affecting occupants of poor, low-income neighborhoods, food deserts are the result of a lack of access to healthy food.
New battery can store 10 times the energy of the next best device
November 30, 2015 07:17 AM - Robert F. Service, Science/AAAS
Industrial-scale batteries, known as flow batteries, could one day usher in widespread use of renewable energy—but only if the devices can store large amounts of energy cheaply and feed it to the grid when the sun isn’t shining and the winds are calm. That’s something conventional flow batteries can’t do. Now, researchers report that they’ve created a novel type of flow battery that uses lithium ion technology—the sort used to power laptops—to store about 10 times as much energy as the most common flow batteries on the market. With a few improvements, the new batteries could make a major impact on the way we store and deliver energy.
Could Lithium-air batteries make oil obsolete?
November 24, 2015 06:47 AM - Editor, The Ecologist
Sooner than it takes to build a nuclear power station, lithium-air batteries could be helping wind and solar to make coal, oil and nuclear obsolete, say Cambridge scientists. Five times lighter and five times cheaper than current lithium batteries, Li-air would open the way to our 100% renewable future.
How to Eat and Stay Healthy this Holiday Season
November 23, 2015 07:23 AM - Patti Verbenas, Rutgers University
When it comes to maintaining healthy lifestyles, people tend to fall off the wagon from Thanksgiving through New Year’s Day. Then, they set “get in shape” and “lose weight” as New Year’s resolutions. That’s not the best idea, says Charlotte Markey, a Rutgers University-Camden psychologist who teaches a course titled “The Psychology of Eating” and studies eating behaviors, body image and weight management. Overeating during the holidays, she notes, is not a matter of if, but when. People need to approach their goals in a smarter way.
Rutgers Today spoke with Markey, the author of Smart People Don’t Diet: How the Latest Science Can Help You Lose Weight Permanently, about a more realistic and sustainable strategy to losing weight and living healthier.
Food industry focuses on sustainable sourcing to mitigate climate change
November 20, 2015 06:59 AM - Sarantis Michalopoulos, EurActiv
Faced with a raw materials scarcity due to climate change, food and drink giants have turned to a sustainable management in order to protect the environment and ensure their future viability. The global population is expected to rise from 7.3 billion today to 9.7 billion in 2050, according to UN projections. As a consequence, according to a survey published in July by FoodDrinkEurope, this will require a 60% increase in food supplies globally, as well as a 30% rise in global demand for water for agriculture.
