Endangered California condors have been the poster birds for calls to get lead ammunition out of our environment, but they might have to make some room for our nation's most iconic raptors thanks to a new study showing how lead ammunition is also harming bald eagles. It might be illegal to hunt bald eagles, but a study conducted by the U.S. Fish and Wildlife Service investigating the link between lead ammunition and bald eagle deaths in the Upper Mississippi River U.S. Fish and Wildlife Refuge.

'Our Ocean' 2014 brought together leaders from business, government and academic institutions, and NGOs from over 80 countries to discuss how economic development and ocean conservation can be reconciled. The oceans are extremely important for humans, generating more than 50 percent of the oxygen we breathe, absorbing excess carbon dioxide, and providing a source of food and income for millions of people worldwide.

Oxford University neuroscientists have shown that fruit flies take longer to make more difficult decisions.
In experiments asking fruit flies to distinguish between ever closer concentrations of an odour, the researchers found that the flies don't act instinctively or impulsively. Instead they appear to accumulate information before committing to a choice.
Gathering information before making a decision has been considered a sign of higher intelligence, like that shown by primates and humans.

We get a little suspicious when we hear the claims that it's possible to get rid of the gunk that accumulates in our cells by doing a cleanse with "clean" foods.
But what if some foods actually do help detox the body?
The results of a recent clinical trial suggest that compounds in cruciferous vegetables like broccoli (and kale) prod cells to get rid of certain air pollutants. The intriguing randomized control trial of about 300 Chinese adults found that consuming a beverage made with broccoli sprouts every day for three months lead to high rates of excretion (in urine) of two harmful chemicals: benzene and acrolein.

Mientras que los pingüinos se han adaptado a un clima extremadamente frÃo, los inviernos duros siguen siendo difÃciles para estas poblaciones especialmente cuando se trata de reproducirse y buscar alimentos. Asà que con el calentamiento global en un futuro cercano, ¿será que las poblaciones de pingüinos estarán mejor? No necesariamente. Sin embargo, un nuevo estudio revela que las poblaciones de pingüinos en los últimos 30,000 años se han beneficiado de alguna manera por el calentamiento climático y el deshielo.

The fine craftsmanship of a spider's web helps these eight-legged arachnids catch their prey. But these silk-threaded designs can tell a spider a lot more than what they will be having for dinner. The spider that sits in the middle of its web monitors the silk threads for vibrations. And according to a new discovery by researchers at the Universities of Oxford, Strathclyde, and Sheffield the frequencies of these vibrations carry specific information about the prey, mates, and even the structural integrity of the web.
