The Great Filter Hypothesis With Neil deGrasse Tyson – The Solution to The Fermi Paradox
Beloved astrophysicist Neil deGrasse Tyson makes a compelling case for why if even intelligent alien life exists elsewhere in the Universe, it is extremely rare. Neil Tyson mentions the fact that the evolutionary tree of life on Earth suggests intelligence is not that important when it comes for survival. Neil deGrasse Tyson also talks about […]
Making Contact – Neil deGrasse Tyson on Alien Life
How would scientists tell the world if they found evidence for alien life? According to SETI, the probability of finding alien life somewhere in the Milky Way is high, based on a number of studies showing that our galaxy contains countless Earth-like planets that orbit sun-like stars. Neil deGrasse Tyson thinks we are probably not […]
How mushrooms clean up the planet (and other fungi powers)
They are mostly invisible, essential for life on earth and could be the building blocks of our future. Here’s how fungi can clean up our soils from the mess we created – and even house us.
Cloud seeding works, but should we still do it?
As temperatures rise, cloud seeding is bound to become a popular solution against droughts, floods, and fires. Do we really have the technology to make it rain? And if so, should we use it?
Can desalination solve the global water crisis?
We have the desalination technology to transform seawater into freshwater. So why are we not using it to solve the global water crisis? We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our […]
Can Sea Water Desalination Save The World?
Today, one out of three people don’t have access to safe drinking water. And that’s the result of many things, but one of them is that 96.5% of that water is found in our oceans. It’s saturated with salt, and undrinkable. Most of the freshwater is locked away in glaciers or deep underground. Less than […]

Brian Cox talks the James Webb Space Telescope and it’s importance for our understanding of the Universe. Throughout history, people have gazed up at the night sky and wondered about our place in the universe. What else is out there? How did it all begin? Are there other planets like Earth? Well the new revolutionary […]
NASA | Show Me the Water
Freshwater seems abundant, but when accounting for all the water on Earth, it’s in limited supply. Just three percent of the water on our planet is freshwater. A majority of this water, about two percent of the world total, is contained in glaciers and ice sheets or stored below ground. The remaining one percent is […]
Making Plants High-Tech With Artificial Neurons | SciShow News
Biology and technology grew closer together when scientists manufactured neurons that acted like those in a brain! And birds evolved to protect themselves in two ways: fight and flight. Hosted by: Hank Green
Is this the world’s oldest animal fossil?
A possible sponge fossil dating back 890 million years could be the oldest animal ever discovered. Not all researchers are convinced that the markings left in the rock were made by an animal but, if they were, the new find could give us an insight into the evolution of the first animals.
