The U.S. Department of Agriculture (USDA) today removed public access to tens of thousands of reports that document the numbers of animals kept by research labs, companies, zoos, circuses, and animal transporters—and whether those animals are being treated humanely under the Animal Welfare Act. Henceforth, those wanting access to the information will need to file a Freedom of Information Act request.

By studying the insects under more-natural conditions, scientists hope to better understand how to eradicate them — and malaria — using an emerging genetic-engineering technology called gene drives. The technique can quickly disseminate genetic modifications in wild populations through an organism’s offspring, prompting some activists to call for it to be shelved. Yet gene drives might not be as effective as activists think. Recent research has identified a major hurdle to using them to eliminate diseases and vanquish invasive pests: evolution.

The goal is to create pig islets that the human immune system won’t recognize as foreign, so they can be transplanted into people.

Immune cells from low-ranking monkeys were less effective at fighting the infection.

In a tour de force of reproductive biology, scientists in Japan have transformed mouse skin cells into eggs in a dish, and used those eggs to birth fertile pups. The report marks the first creation of eggs entirely outside a mouse. If the process could be made to work for humans, researchers could produce artificial eggs without needing to implant immature cells into ovaries to complete their development.

It’s said that dinosaurs went extinct 65 million years ago, but we technically still have dinosaurs running around Earth today (or at least their descendants). Modern-day birds evolved from certain species of dinosaurs, and now scientists have used birds to bring a little piece of the dinosaurs back. In a study published in Evolution, researchers announced that they had successfully grown “dinosaur legs” in chicken embryos.

Dodos, best known for being dead and, well, dumb, may not have been total doofuses. A study published Tuesday in Zoological Journal of the Linnean Society suggests that the birds had brains of about the same relative size as a modern pigeon’s.

Other major poultry producers, including market leader Tyson Foods Inc, have announced plans to eradicate antibiotics, which are also crucial in human healthcare, from their flocks but have not ruled out their use on sick birds.

The U.S Food and Drug Administration said it is asking drugmakers for data on antimicrobials sold for use in each food animal, such as cows and chickens, as part of efforts to combat antibiotic-resistant bacteria.
