While not used much any more as a primary source of light, candles are still everywhere, from an aroma in a bathroom to a mood during dinner. That is, until they’re gone.

Improving batteries is a tough problem, but it’s also an important one because in many ways the future of our planet also depends on the future of batteries. Luckily, scientists are on the case, figuring out ways to give this essential...

This week's SciShow news brings you discoveries involving two of the most exotic substances on Earth - the world's rarest element and the world's oldest water. Two great tastes that taste great together? Stay tuned to find out.

Scientists have had to come up with some extreme ways to generate the extreme pressures needed to simulate the conditions at the cores of planets!

Plutonium powered robot car! With a laser gun! That's (kind of) what's hurtling through space right now as part of NASA Mars Science Laboratory heads for the Red Planet. Hank walks you through this historic mission, with the help of some...

Hank gives us the skinny on three plans NASA scientists have come up with to save Earth from an asteroid impact. Hopefully we'll never have to use any of them.

Welcome back to SciShow News. We are working on creating organisms with a minimal genome to sustain life as well as researching what and how much we inhale with e-cigs.

The exploding “cow” around 200 million light-years away is running astronomers for a loop, but if it is what some hypothesize, we are witnessing a first for astronomy! Meanwhile, we got photographic evidence of a planet orbiting a binary...

In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how...

Voyager 1 may be out of our solar system (and 40+ years old) but we're still getting plenty of new data from our interstellar space probe.

Nobody knows exactly when humans began to create fermented beverages. The earliest known evidence comes from 7,000 BCE in China, where residue in clay pots has revealed that people were making an alcoholic beverage from fermented rice,...

Researchers at Johns Hopkins published a study in December 2019 showing a link between e-cigarettes and depression. This isn’t the first study of it’s kind. There have been others. Depression and vaping are seen as having...

The video discusses the process of hydrocarbon cracking and its purpose, which is to convert heavier, longer chain hydrocarbons into smaller chain hydrocarbons. The video explains two ways to crack hydrocarbons: catalytic cracking and...

Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains...

The video discusses the process of cracking hydrocarbons and why it is necessary, as the heavier fractions of crude oil are not in high demand compared to the lighter fractions which are highly demanded for use as fuels and starting...

This program begins by defining heat of vaporization is the amount of heat that must be added or given off to vaporize one gram or kilogram of a substance and is expressed as J/g or J/kg. Through real, live footage and animation,...

Before 1979, there were less than a dozen known sungrazing comets. As of December 2012, we know of 2,500. Why did this number increase? With solar observatories like SOHO, STEREO, and SDO, we have not only better means of viewing the...

Can we do stoichiometry regarding phase changes? Sure! If we know how many moles of a substance we have, and the energy associated with each mole of that substance undergoing a particular phase change, we can get the energy associated...

With the right methods and technology, it is possible we could one day live on Mars. Here's 10 Ways You Could Survive On Mars.

A pencil lead and some batteries make a small plasma cutter that we use to etch a pattern in aluminium foil. Parts Needed: 4 9V battery, 2 clip leads, 1 5mm pencil lead, aluminum foil, box or tub, rubber band

Learn the basics about Behaviour of metallic structures. How many types of metallic structure do you know? and what are their purposes? Find out more in this video!

The Solar and Heliospheric Observatory, a joint mission between ESA (the European Space Agency) and NASA, was not designed to find comets — its original goal was to study the Sun from its deep core to the outer layers...
