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.

First Solar Panel Bike Path Planned in Amsterdam

As one of the biking capitals of the world, Amsterdam can already make a case for being a leader in the green movement. The city is not resting on its laurels, however. Now, biking around the city is getting even greener than just being car-free: a bike path in the suburbs of Amsterdam is getting a major solar makeover.

How would you feel if electric vehicles were the only ones allowed in center cities?

The subject of making electric vehicles compulsory in city centres in the UK, and indeed many other areas of the world, is one which keeps popping up time and time again. The Liberal Democrat party in the UK has been pushing for greater adoption of electric vehicles within city centres and, don’t shout this, a ban on diesel and petrol vehicles. This is now something of a hot topic and one which will continue to appear in the political domain as we approach general and local elections.

How would you feel about making city centres a no-go area for petrol and diesel vehicles? Is electric vehicle technology of sufficient reliability to support such a dramatic and controversial move?

Raven rescue successful!

Thanks to the kindness of a caring citizen and the expertise of wildlife rehabilitators in Virginia, a common raven has been successfully returned to her home in the wild after being rescued and receiving months of care and a feather transplant.

The raven was first spotted by Maureen Bergin, an IT specialist at Anthem Blue Cross and Blue Shield earlier this spring in the parking lot where she worked in Henrico County with missing feathers that left her unable to fly.

New antibiotic found in mushroom that grows on horse dung

Researchers from the Institute of Microbiology at ETH Zurich and the University of Bonn have discovered a new protein with antibiotic properties in a mushroom that grows on horse dung. The new agent that was found in fungi is found to kill bacteria. The substance, known as copsin, has the same effect as traditional antibiotics, but belongs to a different class of biochemical substances. Copsin is a protein, whereas traditional antibiotics are often non-protein organic compounds.
