Einstein’s theory of general relativity has made countless correct predictions and yet physicists are constantly trying to prove it wrong. Why? What would it be good for to prove Einstein wrong? And how could it be done? In this video I go through the most promising experiments that physicists currently work on which could prove Einstein wrong.

Hydrogen has huge potential as a clean fuel: it’s abundant (mainly in compounds like water), it doesn’t produce any damaging emissions, and it can also be used to store energy from solar, wind, and tidal sources.

There are challenges in producing enough of the stuff in a practical and affordable way, however. Splitting hydrogen from water can require complicated technology and also relies on pure freshwater – not something that’s plentifully available everywhere.

Now, scientists have come up with a new prototype device that can harvest water from humid air, before splitting it into hydrogen and oxygen.

Glioblastoma is one of the most aggressive types of brain cancer known to man. For many, the chance of survival is often low. However, a new type of brain tumor therapy could help change things for the better. The therapy, which relies on destroying the “power source” of the cancer, has shown considerable success in mice. The scientists are hopeful it will work the same in humans.

The new therapy hopes to destroy the “power source” of glioblastoma tumors. A new study led by Israeli scientists shows that glioblastoma relies on specific brain cells to fuel the growth of its tumors. As a result, scientists began to look at ways to treat cancer by removing those cells instead. The new brain tumor therapy could completely starve out the cancer cells, allowing patients to enter remission.

Normally doctors would use chemotherapy to target the tumors directly. However, by removing brain cells called Astrocytes, scientists found they could starve out glioblastoma tumors in mice. Further, the tumors remained gone for as long as the astrocytes were repressed. And, even when they stopped suppressing, Dr. Lior Mayo, lead author on the study, says that 85 percent of mice stayed in remission.

According to the researcher, the same technology could be applied to beetles and cicadas as well.

It’s a fun and futuristic vision: an army of remotely controlled cyborg insects that can infiltrate hard to reach locations or monitor crops.

But scientists will have to advance the tech carefully — nobody wants to risk a cyborg cockroach uprising.

Many insects are powerful, agile flyers. One reason is that most have four wings, which gives them fine control over their direction of flight and their orientation through pitch, roll, and yaw adjustment.

In recent years, aerodynamicists, engineers, and roboticists have attempted to copy insect-like flight by building tiny flying robots. The main thing they’ve discovered is just how difficult this is.

At its height, the Roman Empire was home to about 30% of the world’s population, and in many ways the pinnacle of human advancement. Rome became the first city in history to reach one million inhabitants and was a center of technological, legal, and economic progress. An empire impossible to topple, stable and rich and powerful.
Until it wasn’t anymore. First slowly then suddenly, the most powerful civilization on earth collapsed. If this is how it has been over the ages, what about us today? Will we lose our industrial technology, and with that our greatest achievements, from one dollar pizza to smartphones or laser eye surgery? Will all this go away too?
