Darth Vader the cat isn’t quite as evil as his Star Wars namesake. When his shy tabby sister Charmander enters the room, the chubby black feline rotates his ears forward and opens his mouth just a tad. Then he watches for Charmander to do the same. If she complies, the two begin to chase each other around the house in a spirited play session, before finally snuggling up for a bonding nap.

African wildcats seem to have been part of the human diet in the Levant 10,000 years agoNSP-RF/AlamyAbout 10,000 years ago, foxes and wildcats made up a notable part of people’s diets in what is now Western Galilee in Israel. Archaeologists have long attributed the abundance of small carnivore bones in early Levant settlements to people harvesting fur and to symbolic associations like tooth ornaments.

He’s just a little off. It’s hard to say exactly what’s going on. But he’s your horse, and you know him so well you pick up on the slightest little nuances when something is wrong. So, you check him all over: no signs of injury, no strange bug bites, no drainage coming out of the nose, no diarrhea, no cough. Then you take his temperature. Sure enough, fever. Something is wrong. But what? Welcome to the world of fever of unknown origin.

Have you ever been riding and suddenly gotten that sinking feeling that, well, one of your horse’s legs is sinking with every step? It’s a kind of nondescript sensation that says, “Something’s not right.” It might be that clop-clop-clop-CLOP. Or an ever-so-slightly higher tension in the reins every second step. Maybe it’s how you keep having to shift the saddle upright. Or, maybe it’s something deeper, something in your gut, telling you something’s simply off.

Want to show your mare and breed her, too? You can. Want to get foals from a stallion with low fertility? You can. Want to pass down your gelding’s DNA? You can. You can also ship your mare’s eggs and get her fertilized embryos sent back to you. You can even store embryos for as long as you want and just pull them out of frozen storage whenever you’re ready to make a new foal. This isn’t the future; this is the here and now of horse breeding.

In natura gli scimpanzé sembrano imparare l’uno dall’altro e poi – proprio come gli esseri umani – perfezionare le tecniche apprese generazione dopo generazione. In particolare, le giovani femmine che si spostano da un gruppo all’altro portano con sé il loro sapere culturale, e le comunità possono integrare le nuove tecniche con quelle esistenti per migliorare la loro capacità di trovare cibo.

Inside the digestive system live millions of microscopic organisms that play vital roles in the horse’s digestive—and general—health. Many of these of bacteria, protozoa, archaea, and fungi help break down food and usher nutrients efficiently into the bloodstream. They play a role in metabolizing fiber, generating energy, and promoting proper intestinal transit. While scientists still don’t know what makes up the ideal equine gut microbiota, they do know it’s a question of balance.

The contents of 200-million-year-old faeces and vomit are helping show how dinosaurs took over the world at the start of the Jurassic Period. Well-preserved plants, bones, fish parts and even whole insects embedded in widely varying shapes and sizes of ancient animal droppings suggest that dinosaurs’ broad diets made them survivors in a changing ecosystem, compared with other groups of animals.
