To make ultra-black materials that won’t weigh things down, consider the butterfly

by Véronique Koch and Robin A. Smith, Duke University, Phys.org

Set against a piece of black construction paper, the wings of the male cattleheart butterfly look even blacker than black.

“Some animals have taken black to an extreme,” said Alex Davis, a graduate student in the lab of Duke University biologist Sönke Johnsen.

Sunspots and Stranded Whales: A Bizarre Correlation

by Joshua Sokol, The New York Times –

A collaboration between biologists and an astronomer sought to add evidence to the idea that whale migration is affected by solar weather.

As an astronomer at Chicago’s Adler Planetarium, Lucianne Walkowicz usually has to stretch to connect the peculiarities of space physics with things that people experience on Earth.

Then came the email about whales.

Biologists identify pathways that extend lifespan by 500%

by Mount Desert Island Biological Laboratory, Phys.org

Scientists at the MDI Biological Laboratory, in collaboration with scientists from the Buck Institute for Research on Aging in Novato, Calif., and Nanjing University in China, have identified synergistic cellular pathways for longevity that amplify lifespan fivefold in C. elegans, a nematode worm used as a model in aging research.

The increase in lifespan would be the equivalent of a human living for 400 or 500 years, according to one of the scientists.
