Horses with what’s called Dun coloration sport a mostly pale coat with a few dark-colored markings, like a stripe down the back or a series of streaks on the legs. Most horses these days are non-dun, though Dun is thought to be the ancestral coloration.

The future of butterflies in the United Kingdom is not looking great. A recent report has found that more than three-quarters of the nation’s butterflies have declined in the last 40 years, with many once-common species now on a downward trend. This worrying assessment reveals that while many, in fact most, species are at risk, this doesn’t have to be the case:

Extinct Galapagos Giant Tortoises Could Be Brought Back To Life

When Lonesome George died in 2012, it was thought that so did the last Pinta Island giant tortoise. Discovered roaming the rocky island in the Galapagos archipelago on his own in 1972, it was believed that he was the last of his subspecies. Despite a global search to find him a mate, it proved fruitless over the 80 years of his life. Now, Yale researchers think that his DNA might live on (or at least that of his relatives), diluted in hybrid tortoises found on another island descended from tortoises thrown overboard 150 years ago.

by Tom Hale

The sex lives of Christmas trees are a lot more interesting than their wholesome image suggests. Not necessarily because they’re into kinky stuff, but because they are a certain type of conifer that rely on the ancient practice of “tree sex” to reproduce.

It seems Ebola and terrorism may have lost their scare factor. That is because journalists have once again turned to arachnophobia. “Brazilian Wandering spider found under a bunch of bananas in Waitrose home delivery,” said one newspaper recently.

Explainer: Why Are We Afraid Of Spiders?

by Chris Buddle

I have personal interest in arachnophobia – the fear of spiders – because I am a spider expert, but also because my daughter has it. She is not alone. According to the American Psychiatric Association, phobias affect more than one in ten people in the US, and of those individuals, up to 40% of phobias are related to bugs (including spiders), mice, snake and bats.
There are clearly a lot of arachnophobes. But do they know why they fear spiders? Can they do something to control those fears?

Spiders Identified By DNA Extracted From Their Web

Scientists have successfully managed to extract DNA from spider webs, which not only identified a web's architect, but also what insects the spinner was feeding on. The proof-of-concept study, published in PLOS ONE, used captive southern black widow spiders to show that their webs contained enough fragments of DNA to potentially provide a reliable, non-invasive biomonitoring technique. Not only could the researchers identify the inhabitants of a freshly used web, but even one that had been vacant for 88 days.

Looks more like a Pokemon than a real animal, right? But the 'blue dragon" is quite real. It's actually named Glaucus atlanticus and is a small sea slug found in in tropical and temperate waters throughout the world.

Why You Should Never Feed Bread To Ducks


by Robin Andrews

It seems harmless enough, feeding bread to the ducks in your local park; we enjoy it, the ducks get some food, and everyone’s happy. In fact, in England and Wales alone, we feedsix million loaves of bread to ducks every year – but this is definitely doing them more harm than good. Most bread is essentially junk food to them, although white is the worst, and can cause a range of problems, including a debilitating disease called “angel wing.”

New Duck-billed Dinosaur With A Little Crest Fills An Evolutionary Gap


by Janet Fang

The duck-billed dinosaurs that roamed North America some 77 million years ago were giant herbivores with a flat, paddle-shaped bony crest that completely covered the back of the top of the skull. But the ancestral form that lived just a few million years earlier has no crest. Now, researchers have unearthed the fossils of a new, transitional duck-billed species that bridges the
