Want to Help Fight Wildlife Crimes? There's an App for that!

We know wildlife trafficking has become a huge problem for wild animals and imperiled species, but making it illegal is only part of the solution. Without the ability to identify wildlife products moving through ports, authorities have less power to stop the trade. The good news, according to a recent report published in the journal Biological Conservation, is that conservationists are successfully developing mobile apps to help authorities working around the world with the identification of wildlife that they believe are helping crack down on the problem.

Report Estimates 2010 US Water Consumption is Lowest in Decades

While it may seem that the US is one of the worst culprits when it comes to wasting resources, according to the US Geological Survey, our water consumption is improving. Water use in the United States in 2010 was estimated to be about 355 billion gallons per day (Bgal/d), which was 13 percent less than in 2005. Better yet, 2010 marks the lowest level of water use in the US since before 1970!

Mongoose sentinels coordinate their duty

Just as soldiers on sentry duty constantly adjust their behaviour to match the current threat level, dwarf mongoose sentinels exhibit flexible decision-making in relation to predation risk, new research from the University of Bristol has shown. 

Biologists Julie Kern and Dr Andy Radford found that decisions about when to go on duty, what position to adopt and how long to remain on post were all affected by information about the likelihood of danger. Sentinels altered their behaviour depending on both environmental conditions, such as wind speed and social signals, such as alarm calls.

Groundwater affected by Climate Change

Global warming stops at nothing – not even the groundwater, as a new study by researchers from ETH Zurich and KIT reveals: the groundwater’s temperature profiles echo those of the atmosphere, albeit damped and delayed.

Want some crickets in that energy bar? Startup company Exo thinks you will like it!

If you care about saving the planet, then you really should be eating bugs. While the practice may not be widely accepted in the United States, Exo, a New York company with local connections that makes protein bars using cricket flour, wants to change that.

Exo, which is headquartered in Brooklyn, was founded in 2013 by two recent Brown University graduates, Greg Sewitz and Gabi Lewis. The two co-CEOs are hoping their line of products will normalize eating insects, which, in other parts of the world, are a common low-impact source of protein. In fact, insects contain more protein per 100 grams than dried beef, sirloin steak or chicken breast.

Farmers vs. scientists on the debate over climate change

Crop producers and scientists hold deeply different views on climate change and its possible causes, a study by Purdue and Iowa State universities shows. Associate professor of natural resource social science Linda Prokopy and fellow researchers surveyed 6,795 people in the agricultural sector in 2011-2012 to determine their beliefs about climate change and whether variation in the climate is triggered by human activities, natural causes or an equal combination of both.

Fukushima Radioactivity Detected Off West Coast

Monitoring efforts along the Pacific Coast of the U.S. and Canada have detected the presence of small amounts of radioactivity from the 2011 Fukushima Dai-ichi Nuclear Power Plant accident 100 miles (150 km) due west of Eureka, California. Scientists at the Woods Hole Oceanographic Institution (WHOI) found the trace amounts of telltale radioactive compounds as part of their ongoing monitoring of natural and human sources of radioactivity in the ocean.

Study examines the role of the deep ocean in carbon dioxide storage

The Southern Ocean plays an important role in the exchange of carbon dioxide between the atmosphere and the ocean. One aspect of this is the growth of phytoplankton, which acts as a natural sponge for carbon dioxide, drawing the troublesome greenhouse gas from the atmosphere into the sea. When these plankton die they can sink to the bottom of the ocean and store some of the carbon dioxide they have absorbed, a process scientists call the "biological carbon pump."

Although many areas of the Southern Ocean are rich in nutrients, they often lack iron, which limits phytoplankton growth. An important idea in oceanography is that adding iron to the Southern Ocean could stimulate phytoplankton growth and the biological carbon pump. Some scientists believe that this process can partly explain cycles in atmospheric carbon dioxide over Earth's recent history and it has also been widely debated as a mitigation strategy for climate change.

MIT finds the missing piece of the climate modeling puzzle

In classrooms and everyday conversation, explanations of global warming hinge on the greenhouse gas effect. In short, climate depends on the balance between two different kinds of radiation: The Earth absorbs incoming visible light from the sun, called “shortwave radiation,” and emits infrared light, or “longwave radiation,” into space.

Upsetting that energy balance are rising levels of greenhouse gases, such as carbon dioxide (CO2), that increasingly absorb some of the outgoing longwave radiation and trap it in the atmosphere. Energy accumulates in the climate system, and warming occurs. But in a paper out this week in the Proceedings of the National Academy of Sciences, MIT researchers show that this canonical view of global warming is only half the story.

Water-saving Technology for Rice Farms Introduced

Agriculture experts say application of alternate wetting and drying (AWD) technology in Vietnam’s rice farms, one of South-East Asia’s largest rice-producing countries, holds great promise in cutting water use and greenhouse gas emissions from rice cultivation without sacrificing yield output. Vietnam along with Bangladesh and Colombia recently partnered with the Climate and Clean Air Coalition (CCAC) to introduce the large-scale application of AWD, also known as controlled irrigation in which farmers periodically drain rice paddies rather than keeping them perpetually flooded.
