Dogs are capable of feeling jealousy: U.S. study
23 Jul 2014 | 6:51 pm
Dogs are capable of feeling a basic form of jealousy, according to a study published in the PLOS ONE scientific journal. The research, said to be the first experiment on canine jealousy, could redefine the view that the complex emotion of envy is a human construct, said Christine Harris, University of California, San Diego psychologist and an author of the study.
US wildlife officials propose limiting snake trade

HONOLULU (AP) — Federal wildlife officials recently proposed strict nationwide limits on importing and shipping boa constrictors and four other snake species in an effort to prevent them from being introduced into the wild.
Changing shipping routes could save blue whales
23 Jul 2014 | 3:53 pm
Blue whales off the US west coast like to feed in areas that are heavily used as shipping lanes, a practice that puts their survival at risk, researchers said Wednesday. This habit could be the reason why their population is not rebounding as experts had hoped, and researchers suggested that changing shipping routes could help. For the study, led by Oregon State University and the University of California, Santa Cruz, researchers tagged 171 blue whales off the coast of California from 1993 to 2008. The overall population of blue whales in the area from California, Oregon and Washington in the Northern Pacific Ocean is estimated at between 500 and 2000.
Dogs get especially jealous of other dogs
23 Jul 2014 | 3:41 pm
One of the objects was a toy dog that barked and wagged its tail when a button on it was pushed. Certain dog behaviors were much more common when owners played with the toy dog versus the other objects, the researchers found. For instance, dogs more often snapped, pushed their owners, pushed against the object and tried to get in between the owner and the toy dog than they did with the other toys. The dogs were about twice as likely to push their owner (78 percent of dogs did this) when he or she was playing with the toy dog than when the interaction involved the jack-o-lantern (42 percent).
That's My Owner! Dogs Get Jealous, Too
23 Jul 2014 | 1:53 pm
The first experimental test of jealousy in dogs shows that canines nip even at stuffed pooches when these fakes take away the attention of the dogs' owners. The results also show that jealousy does not require especially complex minds, the scientists said. "Jealousy is the third-leading cause of non-accidental homicide across cultures," said lead study author Christine Harris, an emotion researcher at the University of California, San Diego. It is commonly assumed that jealousy is unique to humans, in part because of the complexity of thought the emotion entails, such as gauging what threat a rival poses to a relationship.
Blue Whales Roam Dangerously Close to Shipping Lanes
23 Jul 2014 | 1:19 pm
The feeding grounds of blue whales along the U.S. West Coast overlap dangerously with shipping lanes, placing the behemoths in danger of collisions with ships, researchers say. Blue whales, along with many other whales, became endangered due to commercial whaling. For instance, in 2008, five dead blue whales were discovered in the Pacific Ocean in a seven-week period, and three of them were confirmed to have been hit by ships. "That made everyone step back and say, 'Whoa, this may potentially be a big problem,'" said lead study author Ladd Irvine, a marine mammal ecologist at Oregon State University.
This free mod makes Watch Dogs look more gorgeous than ever before
22 Jul 2014 | 9:25 pm
Watch Dogs is one of the best games of the year and a decent showcase title for the new generation consoles, but it still doesn’t stand up to the seemingly professionally doctored demo from E3 2012. What we saw two years ago was a game that looked more stunning than just about anything else on the market — the reality wasn’t quite as impressive. Now, just two months after the game’s release, PC modder Federico Rojas (aka TheWorst) has released the final version of his graphics mod for Watch Dogs on the PC, bringing the retail release up to speed with the pipe dream from the original demo. “This is going to be the last version,” Rojas wrote in the 1.0 release
Elephants Can Outsniff Rats and Dogs
22 Jul 2014 | 5:19 pm
Elephants are known for their impressively long trunks, but perhaps less well known is the large number of genes that code for their sense smell. "Rats had the record for the largest number of [these] genes," said the study's lead researcher Yoshiihito Niimura, a researcher of molecular evolution at The University of Tokyo in Japan. The findings support other research on the pachyderm's superior sense of smell. African elephants can smell the difference between two tribes living in Kenya: the Maasai, whose young men prove their virility by spearing elephants, and the Kamba, farmers who usually leave elephants alone, reported a 2007 study published in the journal Current Biology.
Elephants possess 'superior' sense of smell
22 Jul 2014 | 2:50 pm
Elephants possess a sense of smell that is likely the strongest ever identified in a single species, according to a study by Japanese scientists out Tuesday. The African elephant's genome contains the largest number of olfactory receptor (OR) genes -- nearly 2,000 -- said the study in the journal Genome Research. Olfactory receptors detect odors in the environment. "Apparently, an elephant's nose is not only long but also superior," said lead study author Yoshihito Niimura of the University of Tokyo.
Only Zoo Keepers Get to Feed the Penguins (Op-Ed)
22 Jul 2014 | 12:38 pm
Nora Beirne, a senior keeper at the Wildlife Conservation Society (WCS), contributed this article to Live Science's Expert Voices: Op-Ed & Insights. When I went to The College of New Jersey, I was an English major, but I took several pre-med classes. Then, in my senior year, Pat Thomas — associate director of the Bronx Zoo and vice president and general curator for the Wildlife Conservation Society — gave a talk to the biology department. In six years as a zoo keeper, I've trained red pandas for injections, fed black bears jelly off a spoon and held a komodo dragon.
