Ending Wildlife Crime Becomes Top Priority

The past few weeks have been filled with headlines of crimes against our wildlife from the heartbreaking loss of Cecil the Lion to five more elephant deaths. But justice for our wildlife is on the horizon. The United Nations recently recognized that wildlife crime matters, and it’s on a similar level as human, arms and drug trafficking.

Antarctic life is more diverse than previously thought

The team of scientists, led by Monash University, along with colleagues from the British Antarctic Survey, University of Waikato in New Zealand, and Australian National University, looked at how recent investigations have revealed the continent and surrounding ocean is rich in species. They are also very highly diversified into a variety of distinct ecological regions that differ greatly from each other.

Ice cores show volcanic eruptions and cold climate strongly linked

Researchers find new evidence that large eruptions were responsible for cold temperature extremes recorded since early Roman times

It is well known that large volcanic eruptions contribute to climate variability. However, quantifying these contributions has proven challenging due to inconsistencies in both historic atmospheric data observed in polar ice cores and corresponding temperature variations seen in climate indicators such as tree rings.

Are septic tanks doing their job?

The notion that septic tanks prevent fecal bacteria from seeping into rivers and lakes simply doesn’t hold water, says a new Michigan State University study.

What you should know about America's Clean Power Plan

Today, President Obama will unveil the U.S. Environmental Protection Agency’s (EPA’s) Clean Power Plan—a historic step to cut the carbon pollution driving climate change. Here are six key things every American should know...

Trophy hunting is not the main reason for declining population of lions in Africa

Africa has half as many lions as 20 years ago - but don't blame trophy hunting

The killing of Zimbabwe's Cecil the Lion has put a welcome spotlight on the alarming decline of Africa's lions, write Lochran Traill & Norman Owen-Smith. But to save the species, we should not obsess about trophy hunting, but tackle much more serious problems - like snaring and habitat fragmentation.

UN adopts resolution to attack wildlife crime

Faced with an unprecedented surge in wildlife crime, the UN this week adopted a historic resolution committing all countries to ramp up their collective efforts to end the global poaching crisis and tackle the vast illegal wildlife trade.   Initiated by Gabon and Germany and co-sponsored by 84 other nations, the UN General Assembly resolution, Tackling the Illicit Trafficking in Wildlife, is the result of three years of diplomatic efforts and is the first time that every nation has acknowledged the seriousness of wildlife crime and the urgent need to join forces to combat it.  

What actually causes aging?

When does aging really begin? Two Northwestern University scientists now have a molecular clue. In a study of the transparent roundworm C. elegans, they found that adult cells abruptly begin their downhill slide when an animal reaches reproductive maturity.

A genetic switch starts the aging process by turning off cell stress responses that protect the cell by keeping important proteins folded and functional. The switch is thrown by germline stem cells in early adulthood, after the animal starts to reproduce, ensuring its line will live on.

How bees naturally vaccinate their babies

When it comes to vaccinating their babies, bees don't have a choice -- they naturally immunize their offspring against specific diseases found in their environments. And now for the first time, scientists have discovered how they do it.

New study exposes negative effects of climate change on Antarctic fish

Scientists at University of California Davis and San Francisco State University have discovered that the combination of elevated levels of carbon dioxide and an increase in ocean water temperature has a significant impact on survival and development of the Antarctic dragonfish (Gymnodraco acuticeps). The research article was published today in the journal Conservation Physiology.
