"I knew this could cause trouble."

A 30-year debate has just been reignited by a physicist who appears to have found a mysterious new state of matter in an ordinary piece of glass.

For decades, this unexplained phase transition has been sought in real-life materials, and now that we have evidence for it, scientists around the world are trying to understand what it could mean for all kinds of disordered systems in the Universe, from liquids and gases, to grains and galaxies.

The discovery, led by physicist Sho Yaida from Duke University, could take the strange new state of matter out of the hypothetical realm of infinite dimensions, and into reality.

And it’s created quite a stir in the physics community.

“We found hints of the transition that we didn’t dare say was evidence of the transition because part of the community said that it could not exist,” says one of the team, Patrick Charbonneau.

“What Sho shows is that it can exist.”

Newly discovered fossils indicate Homo sapiens were present in Africa 300,000 years ago, scientists reported. Until now, the earliest evidence dated back just 195,000 years.

Fossils discovered in Morocco are the oldest known remains of Homo sapiens, scientists reported on Wednesday, a finding that rewrites the story of mankind’s origins and suggests that our species evolved in multiple locations across the African continent.

“We did not evolve from a single ‘cradle of mankind’ somewhere in East Africa,” said Philipp Gunz, a paleoanthropologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and a co-author of two new studies on the fossils, published in the journal Nature. “We evolved on the African continent.”

Until now, the oldest known fossils of our species dated back just 195,000 years. The Moroccan fossils, by contrast, are roughly 300,000 years old. Remarkably, they indicate that early Homo sapiens had faces much like our own, although their brains differed in fundamental ways.

“Our most conservative estimates of the global volume of the Martian valley networks and the cumulative amount of water needed to carve those valleys are at least 10 times greater than most previous estimates,” Luo said.

Mars has an extensive network of ancient valleys that were likely carved out by water over geologic time periods. Now a new study suggests that Mars had much more water than previously thought, and the key behind calculating that amount of water is in the valleys themselves.

The issue of exactly how much liquid water Mars had on its surface has been a hotly debated topic. There’s ample evidence that there was liquid water there. Orbiters and rovers have provided most of that evidence. Sedimentary rock, hydrated minerals that only form in the presence of water, and the obvious valleys, lake basins, and deltas all show that Mars was once a world with large quantities liquid water.

But to find out how much water there was in Mars’ past, we have to go beyond what we can see with our orbiters and rovers and construct models. That’s exactly what Northern Illinois University geography professor Wei Luo and his colleagues Xuezhi Cang & Alan D. Howard did. To do this, they relied on what previous studies have found, what we know about erosion and water cycles here on Earth, and on an innovative new algorithm that calculated the volume of Mars’ valleys, and how much water would be required to excavate them.

Their new estimate of Martian water volume is 4,000 times the volume of the valley cavities on Mars. This means that Mars would have had an active water cycle much like Earth does. Water would have moved from the lakes and oceans through the atmosphere and over the surface via evaporation and precipitation.

I want one of these masks so badly

The hard structures started forming before the long reign of the dinosaurs, and they did so for a specific purpose.

“When I talked to people, they automatically said it [the turtle’s shell] was for protection. But that never made any sense.”

I watched the Shia labeouf’s motivational video last night and felt really inspired. So I went out and bought a Costco bear that I’ve always wanted Don’t let dreams be dreams.

Update: I no longer have a bed but I have a sweet ass bear though
