Naked mole rats are renowned for their ability to live cancer-free, even when researchers try to induce the disease artificially. Not anymore. For the first time on record, researchers have diagnosed two naked mole rats ( Heterocephalus glaber ) with cancer. [Top 10 Cancer-Fighting Foods] "These cases represent the first formal reports of cancer in the naked mole rat, a rodent species best known for its extreme longevity and apparent resilience to typical health-span-limiting diseases, including cancer," the researchers wrote in the report, published online today (Feb. 17) in the journal Veterinary Pathology. The finding isn't completely out of the blue. The researchers had previously followed a zoo-housed naked mole rat colony for 10 years, and found that some of the animals had precancerous lesions. But the new finding is still the first report of full-blown cancer in the critters, the researchers said. In the first case, a 22-year-old male naked mole rat at the Brookfi...

The world's oldest known wild bird just added a new chick to the family — her 40th one, experts say. The Laysan albatross ( Phoebastria immutabilis ), named Wisdom, is at least 65 years old but shows no signs of slowing down. Wildlife officials at the Midway Atoll National Wildlife Refuge in Hawaii saw her lay an egg on Nov. 28, 2015, and incubate it for several weeks. A fuzzy, gray chick cracked out of its shell on Feb. 1. But Wisdom wasn't there when the baby chick hatched: She had headed out to sea on Jan. 20, leaving her mate on nest duty. She returned just after Super Bowl Sunday (Feb. 7) with a full belly and settled down on the nest, allowing her mate to fly off to sea in search of food, officials said. Wildlife officials wasted no time in naming the chick, dubbing it Kūkini, which means "messenger" in Hawaiian. "Wisdom is an iconic symbol of inspiration and hope," refuge manager Robert Peyton said in a statement. "From a scientific perspective,...

This Valentine's Day, mischievous Cupid will be fluttering about with bow in hand, seeking out mortal hearts to pierce with his love-tinged arrows. But the winged god isn't the only one known for this kind of behavior — oddly, land snails are also known to shoot "love darts." Land snails belong to the gastropod class, which includes thousands of snail and slug species that sport a wide range of reproductive behaviors. Mating for these species typically occurs in the wetter months, said Joris Koene, a biologist at the University of Amsterdam in the Netherlands whose research focuses on love darts.  A Cornu aspersum snail that was hit in the head by a love-dart (arrow) so hard that the dart came out the other side of its head, next to the right eystalk.

Most dog owners know it’s not a great idea to feed their canine pal from the dinner table, but once in a while, pieces of food happen to get slipped to a dog. While this is usually fine, there are some people foods that dogs should absolutely not have. Certain foods can be dangerous or even deadly to your dog. Knowing which ones can help you avoid a tragic accident. I also recommend you to visit a veterinarian and ask them to help you determine a proper nutrition for your dog. 1. Garlic and Onions Keep onions and garlic far away from your dog. Both vegetables are frequently used in human cooking to add flavor, but to a canine they spell trouble. Raw onions and garlic are the most dangerous, but you should avoid exposure to any form of the flavorful foods. Certain compounds within items of the onion family can cause toxicosis in pets. Unfortunately, the symptoms may not show up for three or four days after ingestion. You will notice that your dog seems lazy and his urine will be orange...

Winter is just around the corner! This extremely beautiful season can carry the lives of many animals away, because they often cannot find a suitable place to spend the winter. People are able to use various facilities of a modern and civilized world. A cozy and warm house, a cup of tea and your favorite music can make your winter better and more comfortable. Most animals have no chance to enjoy this cold winter. They live in hope to receive help from us. Unfortunately, only tender-hearted retirees or active workers of different animal rescue groups feed and take care of animals. Young and busy people find charity pointless and unnecessary. They’re often not interested in animal welfare because they cannot make profit on it. What a pity that the society has set new and cruel priorities, but wise people still remember that both bad and good things have a tendency to come back. Parents should be a role model for their children. They should teach their kids to love animals. According to t...

Animals are living creatures and most of us often forget about it. Although they can’t speak our language, they can understand us and they often suffer from human cruelty. Just because people are stronger doesn’t mean they have the right to abuse animals. These little (or big) creatures can’t help themselves at times so they need you to help them. You don’t have to spend money, though. Here are a few ways you can contribute to animal welfare without spending a dime. 1. Volunteer at your local animal shelter If you can’t donate to animal shelters, you can visit a local animal shelter and offer your help. You don’t have to have any special skills to help animals. You can do the simplest things such as feeding animals, taking dogs for walk, cleaning up cages, or participating in fundraising. 2. Report any form of animal abuse If you know someone who hits their pets to death or doesn’t feed them for weeks, report abuse. No one has the right to abuse animals and leave them in hungry, pain, ...

Having a big head might not be such a bad thing, if it means you have a gigantic brain. Animals with bigger brains may be better problem-solvers, according to a new study. Scientists long thought a correlation existed between an animal's relative brain size and its cognitive abilities, but even after decades of research, controversy over the answer abounds. In addition, little experimental data exists on the topic, said Sarah Benson-Amram, of the University of Wyoming in Laramie. So, Benson-Amram and her colleagues put a group of animals to the test, finding that species with relatively large brains for their bodies were the most successful at completing a problem-solving task, they reported on Jan. 25 in the journal Proceedings of the National Academy of Sciences. "There's always been this assumption that if you have a big brain, you're smart. We know that brains are costly energetically, so the species that devote more of their resources to their brain must be doing ...

Scientists have unearthed a monstrous new arachnid lurking in the woods of southwest Oregon — and it's a beast. The new daddy longlegs species, dubbed Cryptomaster behemoth, towers over other creatures of its kind. And like its cousin, the equally elusive Cryptomaster leviathan , the new species is incredibly difficult to find, because it hides out beneath the logs and leafy debris that blanket the forest floor. The Cryptomaster leviathan was discovered in 1969 at one location in the coastal town of Gold Beach, Oregon. The mysterious creature belonged to one of the most diverse suborders, called Laniatores, which contains at least 4,100 species. (Daddy longlegs belong to the arachnid order commonly known as harvestmen, so-called because they often emerge during the fall months during the harvest.) Though the 0.15-inch-wide (4 millimeters) body of the creature is relatively small compared to that of tarantulas or other arachnids, the daddy longlegs towers over other creatures in its...

A cockroach species is one of the only insects in the world that shares some notable traits with humans: Like humans, beetle mimic cockroaches give live birth to their young, and they also seem to be able to provide nutrients from their bodies to their young, similar to the nourishment provided by breast-feeding in humans. Now, one researcher is learning how these creatures developed these traits on the genetic level, and the findings might help to explain these roaches' very mammal-like behaviors. The beetle mimic cockroach ( Diploptera punctata ) is not the same pest you might see scurrying around on your kitchen floor; it is a much smaller species of cockroach that is native to the tropical forests of the Polynesian islands. This cockroach is also one of the few insects that give birth to live young instead of laying eggs. "Not only are they carrying their offspring, but they are prodding them with a milky secretion," Emily Jennings, a doctoral student in the Universit...

Garbage dumps may be such attractive pit stops for some storks that they shorten their migration routes to pay a visit, a new study suggests. A few years ago, Andrea Flack, a postdoctoral researcher at the Max Planck Institute for Ornithology, was tracking the path of white storks from Germany, trying to get close enough to the birds to download flight data from the GPS trackers attached to their backs. Flack eventually found herself standing in an open garbage dump in Morocco, staring at her research subjects. Instead of migrating across the Sahara Desert like many other white stork populations, these birds preferred to spend the winter feeding on trash. "We don't really know yet how much impact it has on their survival," Flack told Live Science. "We can think of it in two ways: On one hand, they have more to eat, and on landfill sites, some populations may increase in size. But we also don't know what kind of long-term effect this waste-feeding has. They might ...
