Scientists are growing tiny cerebral cortexes in petri dishes

1276881891092548496.jpg

In what could be a major step forward for personalized medicine, researchers have perfected a technique for growing miniature balls of cortical tissue—the key working tissue in the human brain—in a dish.

And much, like our brains, these simplified, petri dish brains are abuzz with neuronal activity.

As off-the-wall insane as this sounds, it isn’t just … Read More → "Scientists are growing tiny cerebral cortexes in petri dishes"

Thync wearable claims it can change the way you think

thync_energy_banner-600x346.png

We’ve seen gadgets and wearable that let us control devices and computers, but what if it was the other way around? What if there was a wearable that could change the way we think or, at the very least, the way we feel? Or maybe change the way we spell words. That is, more or less, the promise behind Thync, a new type of wearable that claims it … Read More → "Thync wearable claims it can change the way you think"

A structure for ocean self-cleaning

Boyan Slat wants to rid the Pacific Ocean of half of its plastic waste by 2025. To do so, the 20-year-old and his nonprofit company Ocean Cleanup have designed a simple yet effective floating barrier that will allow the ocean to clean itself. Unlike nets—which sea life can become entangled in—the barriers will skim the surface of the water as ocean currents pass below it, capturing plastic debris in its large V-shaped structure for easy … Read More → "A structure for ocean self-cleaning"

Science teacher suspended for using jammer to shut up students’ cell phones

Standing up for civility is sometimes as hard as standing up for science.

When you try and do both at once, you might have to take the law into your own hands.

Some might, therefore, experience a tinge of twisted sympathy for Dean Liptak. He’s a science teacher at Fivay High School in Hudson, Florida.

For five days, he won’t be a science teacher. He’s been suspended because he got … Read More → "Science teacher suspended for using jammer to shut up students’ cell phones"

Trees trained to grow into furniture

grown-furniture.jpg

Much of our furniture is made from timber. The wood to make that furniture has to be harvested from a felled tree which is then milled, sawed, planed, sanded, put back together with glue and screws, and finished. Wouldn’t it be easier to avoid most of these steps and simply coax a tree to grow into a piece of furniture? That way, it would be one-piece, inherently strong, and could potentially last many years longer than assembled … Read More → "Trees trained to grow into furniture"
