QuoteThroughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

QuoteAs a scientific concept, evolution was revolutionary when it was first introduced. With the help of all three of our hosts and the Smithsonian National Museum of Natural History's new Deep Time Hall, we'll try to explain how evolution actually works and how we came to understand it.

QuoteA documentary with content for consideration in debates between theists and atheists.

Clinton Richard Dawkins, FRS FRSL (born 26 March 1941) is an English ethologist, evolutionary biologist, and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.

QuotePlastic is suffocating the planet, but what if we could make recycling plastic more efficient? This Lawrence Berkeley National Lab team has created a brand new kind of plastic that can be recycled endlessly.

Part 1: How the Metric System Can Get You Killed

QuoteTo celebrate my 10,000, here is the first of two videos exploring how 10,000 has shaped our view of the universe. In part one, we see how a desperate attempt to measure 10,000 km broke lives, exposed hypocrisies, and changed the world.

Part 2: The Planck Reckoner

QuoteIn the second and final part of my 10,000 subscriber special, we examine how Archimedes of Syracuse transformed 10,000 into a poppyseed, and a poppyseed into the unit of the universe.

QuoteCan humanity build an Alcubierre warp drive?
Can we go faster than light?

Dr. Miguel Alcubierre was inspired by Star Trek the Next Generation's example of warp drive faster than light technology on the starship Enterprise. In 1994 he wrote a paper on how we could bend and warp space and time to travel faster than light within the rules of Einstein's general relativity. NASA has and is currently exploring if it is possible to bend the fabric of space and achieve hyper fast space travel with the Eagle Works lab. John Michael Godier spoke with Dr. Miguel Alcubierre on the feasibility of the Alcubierre warp drive and if there has been any developments within physics, including the use of dark matter or dark energy, and anti-gravity, to be able to make this possible.

Biology / Sleep is your superpower
Last post by Unbeliever - June 04, 2019, 04:18:57 pm
QuoteSleep is your life-support system and Mother Nature's best effort yet at immortality, says sleep scientist Matt Walker. In this deep dive into the science of slumber, Walker shares the wonderfully good things that happen when you get sleep -- and the alarmingly bad things that happen when you don't, for both your brain and body. Learn more about sleep's impact on your learning, memory, immune system and even your genetic code -- as well as some helpful tips for getting some shut-eye.

Physics/Chemistry / The Newest Form of Water Is Ho...
Last post by Unbeliever - June 04, 2019, 02:41:30 pm
QuoteIt only took diamonds, x-rays, and a bunch of ultra-powerful lasers to create our newest form of water, Ice XVIII. And it might be the key to unlocking what's inside the mysterious ice planets of our solar system.

"The atomic structure of dynamically compressed H2O is characterized in situ using angular dispersive XRD recorded on multiple image plate detector panels (Fig. 1b). Focusing 16 laser beams on an iron (Fe) foil generates an intense X-ray pulse at 6.7 keV resulting from helium (He)-like atomic transitions. About 2 × 1012 X-ray photons are collimated by the 500-µm-diameter tantalum (Ta) aperture placed immediately behind the target package "

"This suggested superionic ice would conduct electricity, like a metal, with the hydrogens playing the usual role of electrons. Having these loose hydrogen atoms gushing around would also boost the ice's disorder, or entropy. In turn, that increase in entropy would make this ice much more stable than other kinds of ice crystals, causing its melting point to soar upward."

"In stark contrast to common ice, Ih, water ice at planetary interior conditions has been predicted to become superionic with fast-diffusing (that is, liquid-like) hydrogen ions moving within a solid lattice of oxygen. Likely to constitute a large fraction of icy giant planets, this extraordinary phase has not been observed in the laboratory. Here, we report laser-driven shock-compression experiments on water ice VII."

Christianity / EVERYTHING you know about Jesu...
Last post by Unbeliever - June 04, 2019, 10:43:02 am
QuoteNew book Crucifixion's a Doddle by Julian Doyle, uses ancient texts, religious artworks and the Bible itself to refute some of the most common-held beliefs about the death of Jesus.
Doyle's research questions the popular image of the immense wooden cross when there were so few trees in Judea. He points out that the Romans executed criminals by impaling them, while Jewish law preferred stoning them. And why were there no images of the cross for almost four centuries after Jesus' death?
After the attempt to crucify the Monty Python team for their film Life of Brian it became clear to Doyle, the film's editor, that something was seriously wrong with everything we think we know and he began to investigate.
