Researchers have identified a gene in Galápagos finches studied by English naturalist Charles Darwin that influences beak shape and that played a role in the birds' evolution from a common ancestor. The study illustrates the genetic foundation of evolution, including how genes can flow from one species to another, and how different versions of a gene within a species can contribute to the formation of new species.

Humans aren't the only species to be influenced by spin. Our closest primate relatives are susceptible, too. For example, people rate a burger as more tasty when it is described as "75 percent lean" than when it is described as "25 percent fat," even though that's the same thing. A new study finds that positive and negative framing make a big difference for chimpanzees and bonobos too.

A randomized clinical research study looked at the effectiveness of a new treatment for stroke. The study involved adding a minimally invasive clot removal procedure called stent thrombectomy to standard clot-dissolving therapy, known as tissue plasminogen activator. The study showed a dramatic improvement in restoring blood flow back to the brain, which is critical in the recovery of stroke.

The Planck collaboration has released data from four years of observation by the European Space Agency's Planck spacecraft. The aim of the Planck mission is to study the Cosmic Microwave Background, the light left over from the Big Bang. The measurements, taken in nine frequency bands, were used to map not only the temperature of the radiation but also its polarization, which provides additional information about both the very early Universe (when it was 380,000 years old) and our Galaxy's magnetic field.

Researchers have discovered that antibiotics have an unwanted impact on the microorganisms that live in an animal's gut that's more broad and complex than previously known. A study has helped to explain these processes, which are now believed to affect everything from the immune system to glucose metabolism, food absorption, obesity, stress and behavior.
