A team of researchers at MIT are engineering a strain of bacteria, which is similar to the type that causes tuberculosis, to produce biofuel.

The researchers say that the bacteria are useful because they are hungry for a number of sugars and toxic compounds and produce lipids that can be converted to biodiesel.

Dogs and their guides have been transported to the Galapagos Islands as part of a K9 project to track down poachers and reduce crime against wildlife.

The K9 units are now set for regular inspections, beginning at airports, harbors and random checkpoints on all three islands in order to halt illegal poaching activities which have plagued many of the islands’ unique flora and fauna.

In a first, researchers at the University of Washington in Seattle have developed a completely tree-powered electrical circuit.

The nano-scale device—approximately 130 nanometers [a nanometer is one billionth of a meter] in size—consumes just 10 billionths of a watt (10 nanowatts).

Unlike the legendary science fair experiment in which a potato-based electric circuit is created using two electrodes (each electrode being a different metal, which react with the starch, causing a potential difference and thus a current), the UW device utilizes electrodes comprised of the same metal, and is able to generate (output) 1.1 volts. “As far as we know, this is the first peer-reviewed paper of someone powering something entirely by sticking electrodes into a tree,” according to paper co-author Babak Parviz, associate professor of electrical engineering at the UW.

One mountain lion in the Kofa National Wildlife Refuge in Arizona is single-handedly hunting the refuge’s endangered big horn sheep population to extinction.

The puma has already culled at least 15 sheep since last February, a remarkable pace which, if continued, would total 37 deaths by the end of the year. By comparison, the estimated annual yearling recruitment from the Kofa National Wildlife Refuge bighorn sheep herd is only 39 animals.

This picture is a picture of the beautiful Monterey, California coastline. This is where I grew up. It is famous for it’s beautiful sea life. Sea otters, jelly fish, sea lions, kelp forests all populate the Monterey coast.  The Pacific Ocean is the largest ocean in the world. Yet, with all that mass of water, we humans are changing the chemical properties. The acid levels in the pacific ocean, as well as every ocean around the world, are rising. If things keep going this beautiful coastline, my home, will become a wasteland of acid. Habitable to only the most extremophiles.

Rewind our story. Fossil fuels are not just a problem for our atmosphere. When we burn fossil fuels carbon dioxide falls down into the sea. The carbon dioxide is quickly converted into carbonic acid. Carbonic acid has been known to be corrosive to corals and shellfish, and now scientists are discovering that rising acid levels in the ocean are effecting other animals as well.

Austrian scientists are putting the ‘fun’ in ‘fungus’ by forcing organisms which are usually asexual to have sex instead.

The hope is that the fungus would then be easier to breed, which would allow researchers to create organisms that are more efficient at degrading cellulose for the purpose of making biofuel.

Giant poisonous jellyfish are poised to assault Japanese waters, experts warn.

Reports of massive bloomings indicate that this season’s Nomura’s jellyfish spawn should be a big one. The good news is that there may not be a nation on Earth more psychologically prepared for the invasion of giant monsters.

Cold-blooded animals have a lifespan which is exponentially related to the temperature of their environment, a new study finds.

That means that as temperatures increase due to global warming, cold-blooded animals around the world will begin dying younger. Given that the vast majority of animals on Earth are cold-blooded, including the likes of amphibians, mollusks, crustaceans and reptiles, global warming could have unexpected, profound impacts on the world’s ecosystems.

A remarkable dragonfly migration stretching between 14,000 and 18,000 kilometers has been discovered which spans the Indian Ocean.

The migration is by far the longest known insect migration, dwarfing the 7,000km journey of monarch butterflies. Millions of dragonflies make the epic migration every year, which spans from India to the Maldives, the Seychelles, Mozambique, Uganda and back again.

Perhaps the only thing more amazing than the migration is that it has somehow dodged scientific discovery until now. “This just illustrates how little we still know about the natural world,” said Charles Anderson, discoverer of the mass migration.

Phallus drewesii, named after Dr. Robert Drewes of the California Academy of Sciences, is a 2 inch long phallus-shaped mushroom that grows on wood, smells like rotting meat and curves awkwardly downward.

Upon discovering that the new species would be named after him, Drewes remarked: “It is a wonderful honour and great fun to have this phallus-shaped fungus named after me. I have been immortalized in the scientific record.”

25% of all the world’s large-scale terrestrial migrations have already ceased due to habitat loss and human-caused changes to the landscape, and it may not be long before all migrations disappear entirely.

That according to a new study, which warns that with continued population growth, development and habitat encroachment, storied epics like those of wildebeest parading across the Serengeti or herds of bison rumbling across North American plains shall become tall tales of the past.
