Analyses of bones found across the world suggest that the birds entered human settlements more recently than previously thought. But they don’t seem to have immediately made their way to the table, raising questions as to why people started keeping them.

A new study has identified a molecular tradeoff between growth and immunity in moths in response to the administration of subtherapeutic doses of antibiotics, a common practice in animal husbandry.

If signed, the law would boost funding for independent contractors to kill wolves and would allow for more than 90 percent of the population in the state to be taken by hunters.

All six calves inherited the gene for preventing horn growth, but four also got a piece of the plasmid used to introduce the sequence to their dad—complicating regulatory approval.

Like dogs and horses, goats can discern happy from angry facial expressions. But whether these animals possess empathy remains unclear.

While farmers have the green light to grow the genetically engineered plant, FDA approval is still needed before the seeds are sold as food.
