Scientists Grow Vocal Cord Tissue in a Lab for the First Time, and It Produces Sound

Scientists in the University of Wisconsin-Madison have successfully grown functional vocal cord tissue in a laboratory - yes, vocal cords that work. This remarkable new tissue engineering technique could, someday, be used to restore the voices of patients who have certain voice disorders that are (at the present junctures) untreatable.

Roller Coaster Physics.

The principle that underlies the working of a roller coaster is simple. As you ascent to the top, your potential energy builds up. ( i.e the higher you go, longer the distance that the force of gravity can act upon)

This built up Potential energy gets released as kinetic energy downhill. ( Kinetic energy is the energy of motion- linear and rotational). 

Now what Roller Coaster Engineers do is abuse this principle to engineering perfection.

NASA is about to light the biggest human-made space fire ever

If a fire breaks out inside the cabin of a small spacecraft, there’s nowhere to run. But in order to figure out how large fires really behave in space, NASA is planning to light one on purpose. How they’re planning to conduct the test.

Kryptos is an encrypted sculpture by the American artist, Jim Sanborn, that is located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the encrypted messages it bears. Of the four messages, three have been solved, with the fourth remaining one of the most famous unsolved codes in the world. The sculpture continues to provide a diversion for cryptanalysts, both amateur and professional, who are attempting to decipher the final section. The sculptor has given clues on several occasions.

The plate is called a Chladni plate. When he plays it with a bow (you know, like a violin) the couscous aligns itself it certain patterns. We’re not sure if this is science or magic.

Why the Brain Makes Mistakes

A study conducted at Carnegie Mellon University investigated the brain’s neural activity during learned behavior and found that the brain makes mistakes because it applies incorrect inner beliefs, or internal models, about how the world works. The research suggests that when the brain makes a mistake, it actually thinks that it is making the correct decision—its neural signals are consistent with its inner beliefs, but not with what is happening in the real world.

The research is in eLife. (full access paywall)

Researchers Discover Ultra-thin Diamond Nanothreads That Could Support Space Elevator

Today, in order to get to the Moon, an incredible logistical setup is required. From the training needed for astronauts, to the millions of dollars of equipment necessary for space travel, to the cost of rocket fuel—Space flight isn’t easy (or cheap). But what if one can reach the Moon by simply stepping into a small vehicle attached to a cable and pressing a button that says “Moon.”

If what you’re imagining is an elevator, then you are right.

It’s also an idea that several scientists have been trying to realize since 1895, and we have written a number of articles on the feasibility of this tech in the past. Now, with what researchers from the Pennsylvania State University discovered, we may be taking a step closer to achieving that idea.

When they applied alternating cycles of pressure to isolated, liquid-state benzene molecules, surprisingly, it was found that rings of carbon atoms assembled into neat and orderly chains, essentially forming strong ultra-thin diamond nanothreads.
