In the Chiricahua Mountains of Arizona, black-chinned hummingbirds have a clever strategy to keep their nests safe: They recruit unknowing hawks for home security. Hummingbird nests cluster near hawk nests, and those hawks keep away the predatory jays that snatch hummingbird eggs, researchers reported Sept. 4 in the journal Science Advances.

Animal Control in Carlsbad, CA is responsible for dealing with most of the animal related disturbances for San Diego County, including all of the incorporated and unincorporated areas within. But you may be at a loss if you should contact the City of Carlsbad, who contracts with the County of San Diego for animal control services, or if you should contact the county itself. Here are a few guidelines you can follow to make sure that you are contacting the right department, as well as ensuring that you are not putting yourself in any unnecessary risk.
If you are just looking to adopt a pet, license one you have already, or any other pet matter that is unrelated to a disturbance you should contact the County of San Diego directly. They operate three shelters, including the one in Carlsbad, so you should not have to contact animal control in Carlsbad at all for any peaceful inquiries. Carlsbad animal control is mostly responsible for dealing with animal disturbances that pose an immediate threat to people or animals. So be sure
An 80-million-year-old lizard discovered in southern Brazil has provided a surprising clue about how these reptiles evolved, and where they once lived, according to a new study.
Until now, researchers had found acrodontans only in the Old World, including Africa and Asia. (This is a type of lizard is called an iguanian that has teeth fused to the top of its jaws, a group that includes chameleons and bearded dragons.) But the newfound fossil, a partial lower jaw of a new species of acrodontan, shows that they lived in the New World much earlier than thought.
The fossil suggests that acrodontans managed to distribute themselves worldwide before the ancient supercontinent Pangaea broke up about 200 million years ago, the researchers said. [Image Gallery: 25 Amazing Ancient Beasts]
“This fossil is an 80-million-year-old specimen of an acrodontan in the New World,” study co-author Michael Caldwell, a biological sciences professor at the University of Alberta in Canada, said in a statement. “It’s a missing link in the sense of the paleobiogeography and possibly the origins of the group, so it’s
A 17-year-old woman was infected with the rare, but treatable rat-bite fever, that developed from pet rodents that lived in her bedroom, report the doctors who treated her in the online journal BMJ Case Reports.
Rat-bite fever has been reported in writings dating as far back as 2300 years. It was originally described as a disease of the poor, but these days most cases occur in lab workers or in children with pet rodents.
The condition is often goes unrecognised and undiagnosed. Only 200 cases of rat-bite fever have been recorded in the USA since 1839.
Most cases of rat-bite fever involve a bite or scratch from a rodent, but there are several reports of infection without direct bacterial inoculation.
The young woman was admitted to hospital with pain in her right hip and lower back that had continued for two days and led to immobility. Over the proceeding two weeks, she had an intermittent fever, nausea and vomiting, and a pink rash on her hands and feet.
Her nausea and vomiting improved, but the fever continued, and she had tenderness of a joint in her pelvis, and pain in her right leg.
The doctors learnt that the woman had numerous pets including
Caterpillars that munch on corn leaves have developed a clever way to get the most nutrients from their meals: They use their poop to trick the plants into lowering their defenses.
Scientists at Pennsylvania State University recently discovered that fall armyworm caterpillars (Spodoptera frugiperda) can send chemical signals to plants through their poop, or frass.
“It turns out that the caterpillar frass tricks the plant into sensing that it is being attacked by fungal pathogens,” study co-author Dawn Luthe, a professor of plant stress biology at Pennsylvania State University, said in a statement. [In Photos: Animals That Mimic Plants]
Corn plants can deal with only one kind of attack at a time, so while a corn plant is dealing with the perceived “fungal infection,” the caterpillar is left to feast on the plant’s leaves. Normally, a plant will recognize chemical signatures from insect secretions, which helps the plant know when to raise its defenses. In many cases, this includes producing a biochemical that repels herbivores, such as insects.
But chemical signals from the caterpillar’s poop act as crafty diversions, the researchers said.
“The plant perceives that it is being attacked by a pathogen and not an insect, so it turns on its defenses against pathogens,
Animal science researchers at Iowa State University have identified a pair of genetic mutations that cause immune deficiencies in pigs that make them uniquely good models for testing potential medical therapies for people.
The discovery of the mutations will pave the way for researchers to further develop a genetic line of pigs with severe combined immunodeficiency (SCID) at Iowa State and to improve husbandry and management practices for the pigs.
Christopher Tuggle, an animal science professor, said pigs born with SCID make ideal models for studying vaccines, potential cancer treatments and stem cell therapies for human medicine. That’s because their deficient immune systems can’t reject cells introduced experimentally.
“The pig is known to be an excellent model for human biology due to its similar size, physiology and genetic make-up,” Tuggle said. “This shows it has high potential as a model for many areas of testing in regenerative medicine, a new medical specialty that repairs disease instead of treating symptoms.”
Tuggle was part of a research team that published findings recently in the Journal of Immunology, a peer-reviewed academic publication, identifying two genetic mutations in pigs that lead to offspring with SCID. The editors of the journal highlighted the publication for its
Pepper spray is a kind of self defense product. Pepper spray was originally invented by a mailman who has to deal with unfriendly dogs during his work. Pepper spray is a chemical compounds that is used for self defense against attackers and animals. The attackers are generally drug abusers, drunkers and rapists. The effect of pepper spray differs from man to man based on their tolerance capacity. It causes irritability to eyes in the form of tears and pain. The composition of spray includes oleoresin capsicum and OC gas. It is a powerful weapon for self defense for man and woman both. Now a days the policemen also uses this spray on their duty. Pepper sprays are very easy to use. The attacker is on the ground after three minutes if you use pepper say. Pepper spray is very easy to acquire also because you do not need any registration for that.
The effects of pepper spray are very serious that includes: Temporary blindness which can remain for twenty to thirty minutes.
Immediate closing of eyes.
Difficulty in breathing that can last for three to ten minutes.
Difficulty in speaking.
Burning sensation of skin.
Pepper spray are very
Dogs have owners, cats have staff.
Though the old joke is a stereotype of a feline’s independent nature, that trope may have some scientific backing.
Cats do not form the childlike dependence on humans that dogs do, new research suggests.
That doesn’t mean people’s feline friends don’t bond with them, said Daniel Mills, a veterinary behavioral medicine researcher at the University of Lincoln in England.
“This is not about whether cats love their owners,” Mills told Live Science. Rather, it just means that Felis catus doesn’t look to its human owners as a source of safety and security, he added. [Here, Kitty, Kitty: 10 Facts for Cat Lovers]
The new results are based on a test called the “Strange Situation.” In the test, which was developed for humans by psychologist Mary Ainsworth in the 1970s, researchers put a mother or primary caregiver and a baby in one room together and then asked the mother to leave as a stranger walked in to play. Ainsworth found that some tots would play joyfully while their caregiver was around, act fearful or distressed when the caregivers left, and then act happy when the mother figure returned. Those little ones were “securely attached,” Ainsworth said, meaning they saw
an octopus named Paul correctly predicted the outcome of eight World Cup matches in a row, including the final showdown between Spain and the Netherlands.

In 2010, after winning worldwide attention as an animal oracle, Paul passed away at the tender age of two and a half – a normal lifespan for an octopus vulgaris. But a raft of other animals have been competing to fill Paul’s, er, shoes in the 2014 World Cup season. So far, however, the would-be successors to Paul the Octopus haven’t been faring so well.
Nelly the Elephant predicted that the German team would overtake the Ghanians in the second round. The match, however, ended in a tie.
Pele the Piranha predicted that the host country of Brazil would defeat Mexico. This match, however, also ended in a tie.
Flopsy the Kangaroo, a.k.a. the “Predictaroo,” correctly predicted that Brazil would defeat Croatia in the opening match of the World Cup but flopped badly in predicting that Australia would defeat Chile.

Most people likely wouldn’t react well to being surprised by a venomous spider, but recently, scientists at Booderee National Park, on the southern coast of Australia, were excited when a highly venomous funnel-web spider showed up unannounced.
Many species of funnel-web spiders, named for their funnel-shaped webs, are indigenous to Australia, but only one of these species, the Sydney funnel-web spider, is known to live in Booderee National Park.
Sydney funnel-webs (Atrax robustus) are ground-dwelling spiders with highly venomous bites that, before the development of an anti-venom, posed a serious medical risk to humans. Funnel-webs, including Atrax robustus, were believed to be responsible for at least 13 deaths in Australia before the anti-venom became available, in 1981. [Creepy, Crawly & Incredible: Photos of Spiders]
But the spider found along Australia’s southern coast by scientists from the Australian National University (ANU) wasn’t Atrax robustus. In fact, it might be a brand-new species of funnel-web spider, said Thomas Wallenius, a biologist at ANU’s Research School of Biology and one of the scientists who uncovered the arachnid.
“It’s remarkable that we have found this other species in Booderee National Park. It shows we still have a lot to learn about what’s out there in the bush,” Wallenius
Animal cruelty is something that is close to many people’s hearts. Many think of it as an abuse that is akin to child abuse, since animals are also defenseless against the hands or neglect of humans.
It tends to rouse similar anger and outrage as well, and there are now many agencies that are set up to help prevent animal cruelty, and also shelters where rescued animals find solace and comfort from their abusive or neglectful environments.
Years ago, there were not even any laws set up to protect animals from abuse, and abusers were able to get away with doing just about anything they wanted without consequence.
Now, there are animal protection laws set up in almost every state, and if you are found guilty of inhumane treatment of an animal, you are subject to anything from fines to community service, to jail time.
While we’ve come a long way in legislating animal protection laws, there is still room for improvement, as they are not stiff enough penalties in most people’s eyes, and it seems that it’s still taken rather lightly.
While I’m not aligned with the extreme mentality of animal rights groups that preach vegetarianism and use tactics that I don’t deem appropriate
