When a person gets a PET scan to find tumors and see how much cancer has spread, the machine is actually detecting sugar. This is because cancer has a sweet tooth, and this discovery, called the Warburg effect, could help us create better medicines and treatments for cancer. To learn more about how PET scans […]
South Korean scientists have allegedly created a superconductor that works at room temperature and regular pressure. This is a big deal because superconductors transmit electricity with zero resistance and have special magnetic properties that are very useful in technology. Normally, superconductors require extreme cold temperatures, but this new one can apparently work outside the lab […]
Researchers have successfully pinpointed the processes responsible for causing gray hair and conducted experiments aimed at its reversal. Surprisingly, some of these potential solutions have been available for several decades. Watch this episode of SciShow to learn more about how one day, people with grey hair could go reverse their greying condition.
From TED Education: Annually, we shower over 5 billion pounds of pesticides across the Earth to control insects, unwanted weeds, funguses, rodents, and bacteria that may threaten our food supply. But is it worth it, knowing what we do about the associated environmental and public health risks? Fernan Pérez-Gálvez weighs the pros and cons of […]
A light, cheap space telescope design would make it possible to put many individual units in space at once. Katie Yung, Daniel Apai /University of Arizona and AllThingsSpace /SketchFab, CC BY-ND Daniel Apai, University of Arizona Astronomers have discovered more than 5,000 planets outside of the solar system to date. The grand question is whether […]
You and the professor used a DeLorean to go back in time to solve problems with the spacetime continuum. But suddenly, another DeLorean appears, and it has older versions of both of you inside. The professor gets really worried and says that if both sets exist at the same time, it could make the whole […]
Every year, significant quantities of food are wasted by countries worldwide. In the United States alone, approximately one-fifth of food products are discarded due to consumer uncertainty regarding expiration labels. However, the majority of grocery items remain perfectly safe to consume even after their listed expiration dates. If these dates don’t indicate spoilage, what purpose […]
Every day, billions of people depend on a century-old chemical reaction to create a large part of the world’s food supply: combining nitrogen gas and hydrogen gas to create ammonia, and down the line, fertilizers. But this seemingly innocent reaction has a dark side. It devours a whopping 1% of the world’s entire energy supply […]

Hansen, New Mexico State University and Hailey A. Luker, New Mexico State University Now that summer is in full swing, mosquitoes have come out across the United […]
The Sun’s light on Earth varies throughout the year, creating different seasons. In this video, watch the Earth orbit the Sun, spinning like a tilted top. This rotation alters the angle of sunlight, leading to the diverse seasons we experience. Observe how sunlight at different times of the year impacts the productivity of life on […]
