‘Tobacco at a cancer summit’: Trump coal push savaged at climate conference

The Trump team was heckled and interrupted by a protest song at the UN’s climate change summit in Bonn on Monday after using its only official appearance to say fossil fuels were vital to reducing poverty around the world and to saving jobs in the US.

While Donald Trump’s special adviser on energy and environment, David Banks, said cutting emissions was a US priority, “energy security, economic prosperity are higher priorities”, he said. “The president has a responsibility to protect jobs and industry across the country.”

Other attendees at the summit condemned the argument.

“Promoting coal at a climate summit is like promoting tobacco at a cancer summit,” said Michael Bloomberg, the former New York mayor and a UN special envoy for cities and climate change.

Joe Cartledge invented the jockstrap (or athletic supporter) in the 1920s. He played hockey, football, and rugby so his invention may have been inspired by painful, painful memories. It was marketed as “Protex.”

Ban on US Import of Elephant Trophies Remains, For Now

On Friday, President Trump tweeted that he was putting the decision to reverse a ban on elephant trophy imports "on hold," pending a review of "all conservation facts."

How To Fall Asleep And Why We Need More 

The National Sleep Foundation recommends an average of eight hours of sleep per night for adults, but sleep scientist Matthew Walker says that too many people are falling short of the mark.

“Human beings are the only species that deliberately deprive themselves of sleep for no apparent gain,” Walker says. “Many people walk through their lives in an underslept state, not realizing it.”

Walker is the director of the Center for Human Sleep Science at the University of California, Berkeley. He points out that lack of sleep — defined as six hours or fewer — can have serious consequences. Sleep deficiency is associated with problems in concentration, memory and the immune system, and may even shorten life span.

5 Future Predictions For The Human Race

Biologists create beetle with functional extra eye

On “Game of Thrones,” a three-eyed raven holds the secrets of the past, present and future in a vast fantasy kingdom. But for real-world biologists, a “three-eyed beetle” may offer a true glimpse into the future of studying evolutionary development.

Using a simple genetic tool, IU scientists have intentionally grown a fully functional extra eye in the center of the forehead of the common beetle. Unraveling the biological mechanisms behind this occurrence could help researchers understand how evolution draws upon pre-existing developmental and genetic “building blocks” to create novel complex traits, or “old” traits in novel places.

The study’s results appear in the journal of the Proceedings of the National Academy of Sciences. The work also provides deeper insights into an earlier experiment that accidentally produced an extra eye as part of a study to understand how the insect head develops.

“Developmental biology is beautifully complex in part because there’s no single gene for an eye, a brain, a butterfly’s wing or a turtle’s shell,” said Armin P. Moczek, a professor in the IU Bloomington College of Arts and Sciences’ Department of Biology. “Instead, thousands of individual genes and dozens of developmental processes come together to enable the formation of each of these traits.
