Turns out that the bands scientists have been attaching to penguins for 50 years to study them has been doing more harm than good. Because of the bands, penguins are producing fewer offspring and have a lower survival rate–probably because the bands impede their swimming abilities, which makes it harder to gather food. Still, the success of the penguins help indicate climate change, so it’s important for scientists to continue to study them. How? They may switch to microchips.
Penguins Harmed By Tracking Bands, Study Finds
Paleontologists have discovered a new dinosaur! Discovered in northeastern Argentine, its name is Eodromaeus, and at four feet long and 10-14 pounds, it would have made for a cute pet. This dinosaur lived around 230 million years ago, just a couple million years before theropods such as the T-rex existed (it probably evolved into a T-rex). Eodromaeus is similar to another dinosaur that lived around the same time, called Eoraptor. Both could run on two legs and were small in stature, but Eoraptor was probably an ancestor to sauropods (like Apatosaurus).
Pet-Size Dinosaur Was Early Ancestor to T.-Rex, Researchers Say
Thousands of birds have been dropping dead out of the sky lately, and many of those deaths were caused by the birds colliding with buildings. A 2009 study found that at least 9,000 birds crash into buildings in New York City each year.
