Archaeologists Find Ancient Puppy Paw Prints on Roman Tiles
“The paw prints and hoof prints of a few meddlesome animals have been preserved for posterity on ancient Roman tiles recently discovered by archaeologists in England.
"They are beautiful finds, as they represent a snapshot, a single moment in history," said Nick Daffern, a senior project manager with Wardell Armstrong Archaeology. "It is lovely to imagine some irate person chasing a dog or some other animal away from their freshly made tiles."
or, Why Wings Probably Really Evolved
- Controlled Falls: Winged dinosaurs were predators, and would have chased or ambushed prey. Wings would allow them to better control pounces and leaps, as well as slow falls from high places that might otherwise injure them.
- Wing-Assisted Incline Running: Wings can be used by their owners to help them climb steep hills or tree trunks.
- Mantling: Seen in birds of prey even today, wings are useful for hiding prey items from opportunistic passersby who might steal them. Also useful for hiding vulnerable offspring from sight.
- Camouflage: Wings can have intricate patterning that help their owners blend into the background, and also help break up their silhouette- particularly important if your predators have poor color vision, like mammals (and mammals were around long before dinosaurs!).
- Secondary Sexual Characteristic: Glossy, healthy, bright wings and other feathery appendages are indicators of good health, desirable in mates. It’s an honest signal to females that the male is in good condition and can pass those genes on to the offspring.
- Ritualization: The same sexual characteristics can also settle disputes between competing males (or females, if the sexual roles are reversed) without violence. An individual can visually determine if he has a chance in a fight with his opponent without ever fighting. It increases the fitness of both parties.
- Deimatic Behavior: This is defensive behavior, or a startle response. Wings can make a bird (or dinosaur) look much larger than they are, and bright colors and bold patterns can startle a predator and deter the attack.
Every kid loves a flipbook. It’s magic, at first sight, the way flipbooks bring sketches to life one frame at a time. But, horribly, flipbooks might also represent one of the first of many disappointments in a kid’s life: Pages run out, the animation stops dead.
Now, artist Juan Fontanive has discovered the equivalent of flipbook immortality, or maybe the fountain of flipbook youth.
Examples of dogs represented in ancient Mexican art.
All of these artifacts date from 200 BCE to 500 CE. The first is from Nayarit, and the rest are from Colima. The dog in last sculpture is shown to be wearing a human mask.
Maybe this year the Easter Bunny can take the day off and we can celebrate with the Easter Snake instead. Meet Crescent, or in this case “Bunny Crescent”, Canadian DeviantARTist NocturneJewel's leucistic Texas Rat Snake (Pantherophis obsoletus). She’s almost 9 years old, just over 4 feet long, and is probably better suited to hide Easter eggs simply by swallowing them, rather than trying to hide them for the rest of us to find. But we don’t mind.
NocturneJewel had a seamstress friend make this cute pair of bunny ears for Cresent, who apparently didn’t mind wearing them, but only had to do so long enough to take these awesome photos.
It’s Excellently Eccentric Easter Day on Geyser of Awesome!
"What’s up with chicks and science?"
Are there genetic differences between men and women, explain why more men are in science.
I’ve never been female. But I have been black my whole life. I can perhaps offer some insight from that perspective. There are many similar social issues related to access to equal opportunity that we find in the black community, as well as the community of women in a white male dominate society…
When I look at — throughout my life — I’ve known that I wanted to do astrophysics since I was 9 years old…I got to see how the world around me reacted to my expressions of these ambitions. All I can say is, the fact that I wanted to be a scientist, an astrophysicist was hands down the path of most resistance through the forces of society.
Anytime I expressed this interest, teachers would say, ‘Oh, don’t you wanna be an athlete?’ I want to become someone that was outside of the paradigm of expectations of the people in power. Fortunately, my depth of interest of the universe was so deep and so fuel enriched that everyone of these curve balls that I was thrown, and fences built in front of me, and hills that I had to climb, I just reach for more fuel, and I just kept going.
Now, here I am, one of the most visible scientists in the land, and I wanna look behind me and say, ‘Where are the others who might have been this,’ and they’re not there! …I happened to survive and others did not simply because of forces of society that prevented it at every turn. At every turn.
…My life experience tells me that when you don’t find blacks, when you don’t find women in the sciences, I know that these forces are real, and I had to survive them in order to get where I am today.
So before we start talking about genetic differences, you gotta come up with a system where there’s equal opportunity, then we can have that conversation.
Right now, 500 light years away from Earth, there’s a planet that looks a lot like our own. It is bathed in dim orangeish light, which at high noon is only as bright as the golden hour before sunset back home.
NASA scientists are calling the planet Kepler-186f, and it’s unlike anything they’ve found. The big news: Kepler-186f is the closest relative to the Earth that researchers have discovered.
It’s the first Earth-sized planet in the habitable zone of another star—the sweet spot between too-hot Mercury-like planets and too-cold Neptunes— and it is likely to give scientists their first real opportunity to seek life elsewhere in the universe. “It’s no longer in the realm of science fiction,” said Elisa Quintana, a researcher at the SETI Institute.
But if there is indeed life on Kepler-186f, it may not look like what we have here. Given the redder wavelengths of light on the planet, vegetation there would sprout in hues of yellow and orange instead of green.
