The highly anticipated update of the analysis of data from the European Space Agency's Planck satellite starts with a first paper published in Astronomy and Astrophysics, which already holds in store a few major surprises. The first article in fact "rejuvenates" the stars of our Universe. Thanks to new maps of cosmic background radiation (in particular,…

Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they flare up on strikingly regular cycles, ranging from two weeks to 100,000 years—and, that they erupt almost exclusively during…

Termites might not top the list of humanity's favorite insects, but new research suggests that their large dirt mounds are crucial to stopping deserts from spreading into semi-arid ecosystems. The results indicate that termite mounds could make these areas more resilient to climate change. The findings could also inspire a change in how scientists determine the possible effects…

Air travel emits more than 650 million metric tons of carbon pollution annually – equivalent to the pollution from 136 million cars – making the increased use of sustainable biofuels a critical to reducing the industry’s carbon footprint. According to a first-of-its-kind scorecard released today by the Natural Resources Defense Council, the industry is making strides…

When it comes to organic certification, food producers must follow strict guidelines.For an organic steak, for instance, the cow it came from has to be raised on organic feed, and the feed mix can't be produced with pesticides, chemical fertilizers or genetic engineering.Now, the U.S. Department of Agriculture is considering a set of rules for…

The more scientists study pigeons, the more they learn how their brains–no bigger than the tip of an index finger–operate in ways not so different from our own.In a new study from the University of Iowa, researchers found that pigeons can categorize and name both natural and manmade objects–and not just a few objects. These…

Crops and other plants are constantly faced with adverse environmental conditions, such as rising temperatures (2014 was the warmest year on record) and lessening fresh water supplies, which lower yield and cost farmers billions of dollars annually. Drought is a major environmental stress factor affecting plant growth and development.  When plants encounter drought, they naturally produce…

Seabirds, aerial ocean predators, are known to amass harmful contaminants over their lifespan. Scientists believe this exposure to pollutants, such as blood mercury (Hg), cadmium (Cd), and persistent organic pollutants (POPs), negatively impacts survival rates as well as reproduction, therefore contributing to large-scale population declines. Although previously these assumptions were largely theoretical, recent research in…

This post originally was published on WRI.org.How does bioenergy contribute to a sustainable food and climate future?A new WRI paper finds bioenergy can play a modest role using wastes and other niche fuelstocks, but recommends against dedicating land to produce bioenergy. The lesson: do not grow food or grass crops for ethanol or diesel or cut down…

A team of researchers led by Kathryn McKain of Harvard University has recently discovered that approximately three percent of the natural gas delivered to Boston leaks directly into the atmosphere, taking with it a heavy load of methane, a known greenhouse gas. Their study doesn’t just have significant environmental implications: It’s estimated that the city…
