Overall, global CO2 emissions from fossil fuels increased 29% between 2000 and 2008 and 41% from 1990-2008, and the current concentration of CO2 in the atmosphere is now at its highest in at least 2 million years, according to a new study in the journal Nature Geoscience.

The new report published this week by an international team of researchers who are part of the “Global Carbon Project” shows emissions trends through 2008 (including changes in emissions causes and in the amount of emissions remaining in the atmosphere) and brings up some major questions for the future as well.

Oceans regulate our climate. They play a key role in keeping the world’s “homeostasis” in tact. However, their ability to absorb carbon & keep the climate in balance is dwindling, a new report shows.

In a year-by-year study from 1765 to 2008, researchers found that the oceans are struggling to meet increasing emissions demands. They cannot take in as much carbon as they used to.

The study, published in the November 19 issue of the journal Nature, found that the percentage of fossil fuel emissions the ocean has been taking in since 2000 has decreased by as much as 10%.

This is the first study of its kind or breadth. One previous study had attempted to measure the oceans’ industrial carbon absorption for one year — 1994. This does so for a period of 200+ years.

Officials from Iowa and the United States Department of Agriculture have confirmed a pet cat in the United States has tested positive for the H1N1 virus.  This is the first time a feline has contracted the H1N1 virus in the United States, according to the American Veterinary Medical Association (AVMA).

Have you heard the news? Habitat loss, overhunting, and unsustainable development are wiping out the world’s greatest treasure: Wildlife.

The animals and plants that call this planet their home haven’t got a chance if humans keep it up. Wildlife destruction is happening faster than current conservation efforts can replenish – or even stabilize – most endangered species numbers.

Now, the 2009 IUCN Red List of Threatened Species figures are in – and the news isn’t good.

Bacterial evolution can be accelerated with the MAGE technique to produce large numbers of  favorable mutations (micrograph image of E. coli bacteria magnified 10, 000 times)

Bacteria are prolific replicators, and some species can replicate into the millions in just a few hours. Bacteria, in the functioning of their cellular and biochemical machinery, also just happen to manufacture some very useful chemicals and bio-active molecules. The microbe populations also exhibit high rates of random mutation, which can confer adaptive traits, over time, onto the newer, variant population.

These attributes of bacterial life forms have been exploited in the biology lab (and in other industries) for some time, but generating genomic diversity in the lab has been challenging; inserting genes or entire genetic sequences into a cell’s nucleus (and DNA) can be done readily, but controlling or directing how exactly these hybrids mutate, is quite another thing. Further, new phenotypes (the main physical traits or properties) don’t usually happen fast or frequently enough for practical uses. But with a new technique called MAGE (Multiplex Automated Genome Engineering), bacteria are now being engineered (and “directed”) to perform these functions much faster and much more efficiently.

Bats may be considered a spooky Halloween mascot, but they are actually one of the most beneficial animals on the planet: 70% of the world’s bat species feed on insects – and one bat can consume up to 1,000 insect pests in an hour. Bats also play a critical role in pollination and seed dispersal.

Despite the fact that bats occur nearly everywhere on earth (except for arctic and desert extremes), 60 species of bats are listed as endangered. And in the U.S., an estimated million or more hibernating bats of six species have been killed by White-nose Syndrome (WNS) in nine states since 2006.

To help raise awareness for bats, here is a compilation of 10 facts about bats – and a diverse photo gallery of bat species celebrating the surprising cuteness of these creatures. Enjoy! Read the rest of this entry »

Hyenas are not as numerous as you might think: Poison, guns, snares, sport hunting, and habitat loss due to human expansion are taking their toll on the misunderstood hyena.

Hyenas are the subject of perhaps more myths than any other African animal, which has unfortunately led to decades of persecution against these unusual creatures. The rapid expansion of human population into remaining hyena habitat – and the intentional killing of hyenas by humans – will eventually prove to be more than this resilient species can tolerate.

To help raise awareness of hyena conservation, here are 12 surprising things you didn’t know – plus a compilation of beautiful photos. Enjoy! Read the rest of this entry »

Britain’s first IVF white rhino calf has been born at the Colchester Zoo.

The history-making calf is named Zamba, and was welcomed into the world on October 3, following a 16-month pregnancy. His mother, 11-year-old Cynthia, was in labor for three hours and was able to deliver the calf on her own. Zamba’s father, Simba, had died in April at the age of 41.

Rarest of all sea creatures seen in the wild today, once upon a time the seahorse was found in every ocean of the world from 20 feet to 100 feet (area now most frequented by man). Sea dragons and Seahorses are protected globally by CITES (Convention on International Trade in Endangered Species), and now by Seahorse Hawaii.

Incredibly enchanting creatures in the animal kingdom, seahorses have an unusual biology, with a prehensile tail, and eyes that rotate 360% independent of the other, and the seahorse is the only animal in the entire animal kingdom in which the male has a true pregnancy!
