What if we could use brain waves to treat Alzheimer's? Professor and neuroscientist Li-Huei Tsai details a promising new approach to artificially stimulate gamma brain waves using light and sound therapy, to increase connectivity and...

Afterschool Universe is an out-of-school-time astronomy program for middle school students that explores basic astronomy concepts through engaging hands-on activities and then takes participants on a journey through the Universe beyond...

It explains the concept of polarised wave with the help of activity, activity involved polaroid sheets, polarization by reflection, polarization by scatterind and brewsters law.

In this video, we learn about how we perceive colors, including the beloved color pink. While pink is not part of the visible light spectrum, our eyes and brain work together to interpret the color pink from the light bouncing off...

Imagine having the ability to manipulate light waves in order to see through a skull right into the brain, or being able to use lasers to diagnose a bacterial infection in a matter of minutes. At the Center for Biophotonic Sensors and...

When a new NASA space telescope opens its eyes in the mid 2020s, it will peer at the universe through some of the most sophisticated sunglasses ever designed. This multi-layered technology, the coronagraph instrument, might more rightly...

Everything you need to know about gravitational waves. In February 2016 scientists announced the first detection of gravitational waves by humans on Earth. This was a huge, world changing, discovery. The gravitational waves were caused...

Welcome back to the Fluctus Channel for a feature about how colossal submarines lurk under the waves of the oceans and navigate through the mighty oceans. Fluctus is a website and YouTube channel dedicated to sea geeks. Whenever you are...

The Galapagos Islands are a unique and biodiverse paradise, home to fascinating wildlife that cannot be found anywhere else in the world. From the iconic Galapagos tortoises to the only species of penguins living north of the equator,...

This video highlights the alarming rate of deforestation in the Amazon rainforest, primarily driven by activities such as cattle ranching, infrastructure development, and climate change. It emphasizes the devastating consequences of this...

This video provides a brief history of the origin of the weekend, starting from the absence of a nationally agreed break to the demands made by unions for Saturday and Sunday off. It highlights the passing of the Fair Labor Standards Act...

This video explores the origins and evolution of mountain climbing, from its humble beginnings to its popularity as an athletic activity today. It highlights the story of Horace Benedict du Cesur, a Swiss scientist who couldn't climb...

The Everglades is a unique and diverse ecosystem located in southern Florida. It is the largest subtropical wilderness in North America and is home to a wide range of plants and animals, including alligators and crocodiles....

For the first time ever, scientists using NASA's Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at nearl-light speed before being detected...

What we call "light" is actually just a tiny fraction of the broad range of radiation on the electromagnetic radiation spectrum. The entire span stretches from very-low-energy radio waves through microwaves, infrared light, visible...

The atmosphere is dynamic and forever changing to maintain balance. The ingredients of air, sunlight and water allow life to exist on Earth, but they also generate calm scenes like rainbows, as a tornado ends. All storms move moisture,...

We’ve done a surprising amount of exploration on Mars, from its atmosphere, to its surface, and miles deep into its canyons. But mapping its insides has been a quandary that we hadn’t been able to solve until last week!

In the late 2000s, scientists looking deep into space discovered the largest known water reservoir in the universe inside a quasar, orbiting a supermassive black hole. Learn more about quasars and what this water can tell us about the...

In 1965, MIT's Lincoln Laboratory saw their Lincoln Calibration Sphere 1 (LCS-1) launched into Earth orbit. It was an empty aluminum sphere and couldn't do any science of its own. But the world's most boring disco ball has played a huge...

The Event Horizon Telescope Collaboration observed the supermassive black hole at the center of M87, finding the dark central shadow in accordance with General Relativity, further demonstrating the power of this 100 year-old theory.

Researchers using NASA's Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. The object sets a new record for the most luminous gamma-ray pulsar known. The pulsar lies in the...
