Chimpanzees lay down mad beats to communicate

Apart from their rich vocal palette, chimpanzees drum on trees to communicate over long distances. A new interdisciplinary study, led in part by PhD student Vesta Eleuteri and primatologist Cat Hobaiter from the University of St. Andrews, has explored the details of the rhythms they used, and found that different populations drum with rhythms which are similar to the beats in human music. The research was published in the journal Current Biology.

An exciting new fossil of an early ancestor of modern birds gives insight into evolution

Archaeopteryx, a 150 million year-old bird-like dinosaur, is known from about a dozen fossils found in . A new one that has been studied at Chicago’s Field Museum may be the best preserved yet, and is giving researchers like paleontologist Jingmai O’Connor new insights into how the ancient animal moved around the Jurassic landscape. The research was published in the journal Nature.

A house with good bones — in more ways than one

Inspired by the structure of bone, researchers have created limestone-like biomineralized construction materials using a fungal-scaffold that they seeded with bacteria. Montana State University’s Chelsea Heveran said they demonstrated they could mold it into specific shapes that had internal properties similar to bone, and that it remained alive for a month. It’s early days yet, but she envisions a day when they can grow living structural material on site that may even be able heal themselves. The study is in the journal Cell Reports Physical Science. 

A different kind of emotional band-aid

Scientists have created a clever combination of physical sensors and computer technology to produce a flexible band-aid like device that can accurately read emotions when it is stuck to the face. It’s not quite mind reading, but could give physicians better insight into the emotional state of their patients. Huanyu Cheng of Penn State led the work, which was published in the journal Nano Letters.

A scientist explores what it takes to live a longer, better life

Do you want to live forever? As he noticed himself showing signs of age, immunologist John Tregoning decided to find out what he could do to make that possible. So he explored the investigations that scientists are doing into why we age and die — and tried a few experiments on himself. Bob speaks with him about his new book Live Forever? A Curious Scientists’ Guide to Wellness, Ageing and Death. 

Tregoning dutifully documents everything he discovers as he undergoes testing for his heart, gets his genes sequenced, has a bronchoscopy, and follows an extreme diet, among other experiments. But he comes to the conclusion that “when it comes to improving life outcomes, exercise considerably trumps nearly everything I am planning to do whilst writing this book.”
