Apr 25, 2019

By Meredith Fore One of Stephen Hawking’s most famous theories about dark matter — that this mysterious and invisible substance is made up of primordial black holes — recently suffered a huge blow. That conclusion comes from a massive telescope that captured an image of an entire galaxy in one shot. The findings don’t completely rule out Stephen Hawking’s …

It’s Starting To Look Like God Won’t Save Us From Global Warming
Apr 25, 2019

By Dan Vergano God help us, but it looks like religion isn’t the answer to climate change. Nearly four years ago, Pope Francis released a groundbreaking letter, Laudato Si, On the Care of Our Common Home, calling on the world — and its 1.2 billion Catholics — to curb manmade global warming. “We are presently witnessing a …

Vast Expanses of Rock on Earth’s Surface May Act Like a Natural Solar Panel
Apr 24, 2019

By Yasemin Saplakoglu Scientists have found electricity flowing in an unexpected place — across the surfaces of rocks. Mineral coatings on rocks turn sunlight into electricity, turning on like a light switch when the sun hits them, according to a study published April 22 in the journal Proceedings of the National Academy of Sciences. Plants use …

Scientists: We kept pig brains alive 10 hours after death. Bioethicists: “Holy shit.”
Apr 23, 2019

By Brian Resnick Around 15 minutes after a mammal’s brain is cut off from oxygen, the organ is supposed to die. Without life-giving oxygen, the cells of the brain quickly starve. Some of the cells burst open, while the chemistry of others becomes so imbalanced that their membranes break down. This frenzied spiral ends one …

Part-revived pig brains raise slew of ethical quandaries
Apr 22, 2019

By Nita A. Farahany, Henry T. Greely, and Charles M. Giattino Scientists have restored and preserved some cellular activities and structures in the brains of pigs that had been decapitated for food production four hours before. The researchers saw circulation in major arteries and small blood vessels, metabolism and responsiveness to drugs at the cellular …

99.9999% chance humans are causing global warming, and other science-based facts on climate change for Earth Day
Apr 22, 2019

By Doyle Rice and Elizabeth Weise Climate change is real and increasingly a part of our daily lives. New research and studies out in just the past six months highlight the latest facts about the human-caused shift to our global weather systems and its effects on our planet. First among them, there’s no longer any question that rising …

Apr 19, 2019

By Yasemin Saplakoglu A tiny bone hidden in the tendon of the knee started to disappear over the course of human evolution … or so scientists thought. Now, a new study finds that this so-called fabella (Latin for “little bean”) is making a comeback. The bone, which is a sesamoid bone, or one that’s embedded …

Planet’s ocean-plastics problem detailed in 60-year data set
Apr 19, 2019

By Matthew Warren Scientists have uncovered the first strong evidence that the amount of plastic polluting the oceans has risen vastly in recent decades — by analysing 60 years of log books for plankton-tracking vessels. Data recorded by instruments known as continuous plankton recorders (CPRs) — which ships have collectively towed millions of kilometres across …

The positively charged molecule known as helium hydride is believed to have played a starring role in the early …

Hours After Pigs’ Death, Scientists Restore Brain Cell Activity
Apr 18, 2019 · 1 

By Rachael Rettner In a radical experiment that has some experts questioning what it means to be “alive,” scientists have restored brain circulation and some cell activity in pigs’ brains hours after the animals died in a slaughterhouse. The results, though done in pigs and not humans, challenge the long-held view that, after death, brain …
