Despite thousands of years of coexistence, exploitation and cheese, humanity seems to have missed an intriguing fact about cows: they like to point north. Or possibly south. After some exploration, it was found that other animals, such as deer, do this too.
Researchers have explored the matter and found that the ruminants are aligning themselves to magnetic north, not true north. In other words, this is about the magnetic field, not maximizing heat from the sun or getting out of the wind.

BLUETONGUE is back. It has survived another winter in northern Europe, and now farmers are vaccinating livestock in a race against the biting midges that carry the virus.
The first cases of the disease, which affects ruminants, began to surface this month, with France so far reporting 260. Most are located along the front line of last year's outbreaks, suggesting that the epidemic is spreading into new territory despite France's compulsory vaccination policy.
In England, voluntary vaccination has been rolled out across the country from the south-east, where bluetongue arrived last year

Ewes infected with scrapie, the sheep equivalent of mad cow disease, can transmit the disease to lambs through their milk. Should we be worried? Does BSE spread to calves or even humans in cows' milk? And do mothers with variant Creutzfeldt Jakob Disease (vCJD), the human equivalent of BSE, spread it to breastfeeding infants?
And after reading this study, you will find the answer.

If you were a zebra, how would you spend your days? Daniel Rubenstein and collaborators suggest that the zebras are like grass vacuum cleaners, chip-clipping away at the vegetation as they move. From that, people come to understand that wildlife and livestock are not necessarily antagonistic."No longer are [zebras] necessarily vermin that are viewed negatively by the community," Rubenstein said. "They now have some economic worth."

It is estimated that between 9 and 13 million kilograms of antibiotics are used annually in the United States for raising livestock, with the majority being used for growth advancement and disease prevention purposes. Large amounts of antibiotics fed to livestock are excreted and end up in animal manure, which is commonly applied to agricultural land to provide crop nutrients. Therefore, food crops grown on manure-altered soils are exposed to antibiotics.
