Scientists have developed devices that move us one step closer towards eliminating the need for animal testing. These working miniature artificial brains would be ideal for testing drugs research, neural tissue transplants, or experiments with stem cells.
In a monumental decision, British Petroleum (BP) was fined $20.8 billion for the 2010 oil spill in the Gulf of Mexico; this upgrades the initial deal from the $18.7 that were previously discussed and represents the largest corporate settlement in US history. This money is additional to the reported $28 billion spent on cleanup and compensation.
In the wake of the Chernobyl nuclear power plant explosion in 1987, hundreds of thousand had to move immediately without notice. Their lives changed forever. Many didn't have time to pack anything, as documented by the ghost towns around the fallout site still littered with toys, valuable items and other personal belongings. But while humans had much to suffer, the same can't be said about the wildlife. In the almost four decades since the dramatic disaster, wildlife and vegetation has simply sprung to life like never before. In some instances, there are more wildlife per square meter than in some of the busiest protected natural parks in neighboring Belarus. Turns out wildlife doesn't mind that much radiation - what they mind is humans.
When it comes to human waste products and pollutants, plastic claims the crown. There are very few things our planet can throw at it to get rid of the polymer. It becomes bendy and rippy and shredy but it just won't go away. When you compound the resilience of this headstrong material with the sheer quantities of it that we dump into the oceans, it looks like a pretty one-sided battle that nature can't win, despite all our desperate efforts to increase recycling and take it out of landfills. But now it seems that mother nature still had a trick up her sleeve, and the non-biodegradable reign of plastic is about to come to an end, undermined by the heroic appetite of the mealworm.
Further increasing their conservation efforts, New Zealand will develop the world's largest oceanic sanctuary - twice as big as their entire country.
Enticed by warming waters, king crabs might soon make a run for Antarctica's continental shelf where they haven't been seen for at least 10 million years. As such, the fragile wildlife comprised of creatures like sea stars, sea worms, sponges, sea anemones, sea lilies and feather stars - all lacking protection against the crushing claws of the king crab - could face rapid annihilation.
"Hey, what did you find" "We found a bio-florescent turtle!", a researcher triumphantly declared. David Gruber, a biologist at City University of New York, and colleagues made the find while diving in the Solomon Islands this July. Previously, researchers have found ever growing evidence of bio-luminescence and bio-fluorescence in the animal kingdom, from coral to seahorses, but this was the first time anyone has laid sight on a glowing reptile.
Endemic to Andes Mountains of Chile, Argentina, Bolivia and Peru, the Andean Cat is one elusive feline. It's only been sighted a couple times in the wild, let alone photographed. Some researchers were lucky though after their camera traps photographed a gem: an adult and her kitten.
A new paper published Thursday in Science looks at how climate change is (out of all things) making the tongue of some bumble bees shrink. Two species of alpine bumbles in the Rocky Mountains already show a decrease in tongue volume of nearly 25 percent in the last 40 years; and smaller tongues could spell big trouble for the flowers that rely on bumble bees for pollination.
A new species of plant-eating dinosaur was discovered in Alaska, a variety of hadrosaur -- duck-billed dinos that roamed in herds, said Pat Druckenmiller, earth sciences curator at the University of Alaska Museum in Fairbanks. Researchers named the creature Ugrunaaluk kuukpikensis (oo-GROO'-nah-luk KOOK'-pik-en-sis), meaning "ancient grazer," chosen by scientists with assistance from speakers of Inupiaq, the language of Alaska Inupiat Eskimos.
Florida's farmlands are under attack by a highly destructive pest, the Oriental Fruit Fly, and authorities have quarantined some 85 square miles of land and the food grown there in an effort to contain the insect.
A video of an ape, breaking out of its cage and attacking; the victim -- a human scientist, that picks up a small red hammer and defends himself, battering the primate ran amok. It sounds like a pretty gruesome video, bound to have animal right's activists redouble their efforts to see the heartless jailers brought to justice. But hey, wait a minute... Apes don't wear sneakers.
The Arctic is overrun with giant mosquitoes: larger, furrier versions of the mosquitoes we all know and hate. As temperatures in the Arctic continue to rise, these mosquitoes can not only brood for a longer period of time, but they can survive more, in higher numbers. According to a new study published in the Proceedings of the Royal Society B: Biological Sciences this is a major problem, and one that will continue to grow as the planet gets hotter.
An experiment has found that domestic dogs have lost some of their problem solving abilities, and wolves currently do a much better job than them. In her paper published in the journal Biology Letters, they describe this result, and also offer a possible explanation.
The Netherlands has joined the list of European countries that have banned wild animals from their circuses. The Netherlands will be prohibiting the use of all wild animals for performance (except performance zoos).
Corn farmers around the world owe bats at least $1 billion, seeing how they ward off pests like insects. The findings were made by a group at Southern Illinois University who devised an experimental exclosure in order to estimate bats' contribution to pest control.
A insightful incursion into the lives of sperm whales shows just how similar these gentle marine giants are to us. Not only do these highly social animals communicate through a language, made up of patterned sets of clicks called codas, but they also have dialects. These dialects may be unique to each clan of sperm whales, which may include thousands of individuals. Moreover, the language is learned and not inherently transmitted - a prime example of culture, if anything else.
Researchers detected unusually high levels of toxic metals, including the dangerous neurotoxin methylmercury, in a pristine coastal area and lake. This was surprising given there were no nearby industrial sites or other runoff pollution sites. They found that the toxic substances were leached by two unexpected sources: moulting elephant seals and bacteria.
The humble termite only has its body, saliva and some soil to work with, and the only blueprints it has are instinctual, based on variations in wind speeds and fluctuations in temperature as the sun rises and sets. Working with such limited resources, they still erect monumental mounds that, a new study reveals, rely on a surprisingly well-tuned mechanism for efficient ventilation, something architects today still struggle with.
Adult domestic cats do not view owners as the main provider of security and safety.
Lawmakers from the state of California have passed a law banning the sale of all ivory and rhinoceros horn products in the state. The move was made in an attempt to protect the critically endangered species which are being hunted massively. All ivory owners have until July 1 to get rid of all their products, after […]
The results of a new study offer insight into the workings of predator-prey mechanisms, more specifically how the number of herbivores and other animals that are preyed upon affect the number of carnivores.
One of the planet's most endangered antelope, the saiga, suffered from a die-off of unprecedented scope. The massive loss of life from just a few weeks ago has conservationist groups worried about what future may hold for the species. But clues as to exactly what wiped out half of Kazakhstan's saiga are starting to emerge, and scientists are looking at bacteria that normally co-exist with the antelope host, harmlessly living in their bodies as the main culprit.
Calm and calculated - a chimp at a Dutch zoo took down a drone, squashing it with a tree branch. That's pretty interesting (and a bit sad, if you're the drone owner), but according to a paper published in the journal Primates, it may have more significance than it seems. According to the publishers, the chimp carefully planned the attack, just like a human would.
Picture this: A city under siege. Many of the outlying buildings are old, dry, lifeless shells of their former beauty as nearly 50 percent of the population is wiped out, consumed by ravenous invaders. And the only hope of lifting the siege lies with a poison injecting, yellow robot.
Seahorses are a unique oddity seeing how males, not females, carry the pregnancy and deliver the young.
Thousands upon thousands of Pacific walrus were captured by photographer Gary Braasch as they came ashore on the northwest coast of Alaska last week, in an event believed to be triggered by global warming.
Researchers studying the plastic problem our ocean is facing predict that by 2050 nearly every single maritime bird species will have plastic pieces inside their digestive systems. The grim prediction is based on a new study showing that about 90 percent of seabirds today have plastic in their bodies.
Big Sur, California will see the newest installment of the Big Brother franchise, but with a twist. A team of wildlife conservationists have installed live-streaming web cameras on condor nests in the area, allowing scientists and enthusiastic bird watchers the world over to take a peek into the lives of Gymnogyps californianus.
It's hard to believe anything can be alive thousands of feet below the Indian Ocean where thermal vents effectively boil the water. Yet even in the most inhospitable conditions, life has a way of creeping in. Such is the case of chrysomallon squamiferum, a snail-like creature which may very well sport the best armor in the animal kingdom.
North America boasted about half a million eagles before Europeans colonized the territory. They took the influx of Old World-ers quite harshly: the loss of habitat, the strains put on them by hunting activities and the spreading of pesticides among many others resulted in a steep decline of their population in the US. In 1997, the state of Virginia reported to have only about 50 bald eagle nests occupied by the avian predators. Thankfully, their numbers are slowly increasing at present, with more than 1,000 sightings of active nests throughout the Commonwealth.
Peter Ward might be the luckiest biologist ever. In 1984, he and colleague Bruce Saunders were among the first to identify a new nautilus species called Allonautilus scrobiculatus. Since then, the spiral shelled creature was only spotted once then disappeared for nearly three decades. This year, Ward returned to Papua New Guinea to survey nautilus populations and found the rare nautilus species once again!
The officials of Lake Havasu have taken a laudable measure: they’re offering free mussel decontamination for boats, in an attempt to stop the spread of a very dangerous species, the quagga mussel. The quagga mussel (Dreissena bugensis) is a species of freshwater mussel named after the quagga, an extinct subspecies of African zebra. A rather interesting […]
Possibly the most hyper animal, the hummingbird, feeds by darting its thin tongue 20 times per second inside the flower to extract the precious nectar. Previously, biologists thought the nectar was being collected through capillary motion. However, after analyzing 18 different hummingbird species while they fed using high frame rate cameras, a group at University of Connecticut found that the fast flapping birds use a totally different way to suck food: the tongue employed as a tiny pump.
Octopuses are like aliens and there are few creatures weirder than these eight legged critters. They survive freezing waters, perceive light through their skin, are masters of camouflage and can do many other things, some still oblivious to science. One uncanny feature of octopuses is their mating behavior or social order. Most octopus species mate at a distance, with the male using its reproductive arm to reach the female's mantle. They have to do this to avoid being cannibalized by the female. Either way, once the job is done, the male dies while females only lives a little longer, just enough to lay the eggs. That's the peak of both the octopus' sex and social life. Besides a few instances, octopuses live their lives in isolation, alone in some shell or barren rock. However, there's one octopus that seems to be totally different, even human-like: the Larger Pacific Striped Octopus.
Every year, over 30,000 elephants are murdered, slaughtered for their tusks. Ivory is an extremely valuable commodity, and many people will stop at nothing to get it and sell it. With this in mind, investigative journalist Bryan Christy set out to see what the smuggling route is, so he commissioned a taxidermist to create two fake ivory […]
Maybe the most amazing of social insects, ants use complex cues of pheromones to determine to which cast in the colony each individual ant belongs to. A team at University of California at Riverside found ants do this by sniffing out hydrocarbon chemicals present on their cuticles (outer shell). These cues are extremely subtle, but the ants can sense them with great sensitivity due to the way they're hardwired. It's enough to notice that ants have more olfactory receptor proteins in their genome than we humans have. Amazing!
The buzzing racket of quadcopters and drones may be stressing wildlife, a new study shows. Drones have long ceased to be the provision of the military, and are now extensively been used for civilian purposes. Amazon, for instance, wants one day to deliver all its goods with unmanned aerial vehicles. In research, drones have proven to be particularly useful in observing wildlife. But these aren't as unobtrusive as some might believe and future research should take into account that flying drones overhead should be done carefully so as to not disturb the wildlife.
Some conservationists are considering introducing the Tasmanian devil, currently only found in Australia's island state of Tasmania, back to the mainland. The devil went extinct on the mainland some 3,000 years ago, and scientists hope the predator might restore balance to the local ecosystem, currently destabilized by too many cats and foxes.
A female gray wolf and a male brown bear were spotted every day for ten consecutive days, spending time together, playing and even sharing food. “It’s very unusual to see a bear and a wolf getting on like this” says Finnish photographer Lassi Rautiainen, 56, who took these surprising photos. From what I could find, […]
A new highly infectious diseases has been observed in tadpoles from three continents, threatening global populations. The disease, which was identified and described by British scientists, is a distant relative of an oyster disease. “Phylogenetic analyses revealed that this infectious agent was affiliated with the Perkinsea: a parasitic group within the alveolates exemplified by Perkinsus […]
It's a tough year for salmon all around the world - now, a new health advisory issued by the U.S. Geological Survey, Bureau of Reclamation and PacifiCorp raises concerns about the future of salmon in the Klamath river in Oregon and California.
Sea animals are dying off in huge numbers off the Pacific coast from Baja, Mexico - all the way to Alaska; there's a good chance we can't really do anything about it.
A $13.8 bn railway project funded by China linking Nairobi to Mombasa will pass right through the Nairobi National Park. Although the park hosts a huge amount of tourism and boasts a very sensitive wildlife, authorities are adamant in seeing the railway built.
Nabire was a 31-year-old Northern White Rhino from the Dvur Kralove Zoo in the Czech Republic. She suffered from uterine cysts, which made it impossible for her to breed naturally, and ultimately, one of those cysts brought her demise. She was also one of the last 5 white rhinos on the Earth.
When it comes to vaccines, the young bees don't really have a choice - they're naturally immunized against specific diseases commonly found in their environment. For the first time, researchers have figured out just how they do it.
Different ant species employ various tactics to forage food and keep the colony in tip top shape. Most often scouts will scour for food, and when a source is deemed fit a trail of pheromones guide worker ants to pick up the crumbs, leftover pizza or cheerios. Ants aren't very picky, you know. What they are is very strong. It's common knowledge that ants carry loads multiple times heavier than their own weight. Some species, like longhorn crazy ants are able to carry some of the biggest loads among ants by working together, joining in a band to perform the lifting. It's a curios matter, one you might have often noticed in your very own backyard.
Dolphins in European waters are struggling to reproduce because of the chemical pollution that lingers in their bodies for a very long time - even for their entire lifetime. Scientists were surprised to find polychlorinated biphenyls (PCBs) in their bodies, as PCBs have been banned 30 years ago.
In a first of its kind experiment, biologists found out to everyone's surprise that boa constrictors kill prey by cutting the blood supply from the heart. It was long thought that suffocation is the snakes' modus operandi. This makes sense though, according to evolutionary biologists involved in the study. Cutting the blood supply kills prey much faster than limiting oxygen intake. This comes at an evolutionary advantage since this minimizes risks faced from predators.
Japan’s Twittersphere has just rediscovered (and is loosing its collective mind over) what is probably the cutest sea slug ever – Jorunna parva, a sea slug that looks like a fluffy bunny.
