How to Cure Cancer With RNA

In addition to safeguarding us from diseases, our immune system also helps protect our bodies from itself by watching out for cancer. And that prompts the question: Could our immune system give us a leg up in developing vaccines to combat cancer? Enter vaccines based on the genetic code, specifically RNA and DNA. This approach is supposed to be faster and easier than traditional vaccine development. All this progress means we are getting closer to directing our own cells to make any protein our immune system needs. Host Michael Aranda fills in the details in this episode of SciShow.

Stealth: Hiding a Plane

There’s a reason why the Zumalt-Class Destroyer and B-2 Spirit plane look so strange–they’re designed for stealth. The two main obstacles for such objects are radar and infrared detection, but improved technology is finding ways around these systems. SciShow’s Michael Aranda explains.

How Space Shaped Our DNA

The DNA in our cells have a finely tuned sense of aesthetics, so much so that they are almost exclusively right-handed. This biological preference in the DNA helix is strict and oddly holds in all lifeforms. Science has determined that the phenomenon is due to the DNA building blocks, or nucleotides. But the more conclusive answer may have come from space. SciShow host Michael Aranda explains.

Dinos: Cold Or Warm Blooded?

Scientists have debated for decades whether dinosaurs were warm-blooded creatures or cold-blooded killers. Host Michael Aranda says that it turns out dinos were somewhere in the middle. He helps solve the metabolism puzzle for these magnificent creatures in this edition of SciShow.

The Evolution of Music

Popular music has evolved in the last 50 years in ways that would make Darwin proud. To document the evolution of popular music, researchers from both the biology and music genres analyzed the songs on the Hot Billboard 100 from 1960 to 2010. Their theory was that like life, culture evolves. Host Michael Aranda divulges the surprising results of the study and also takes a look at how sleep-walking and sleep terrors are genetically linked in this edition of SciShow.

The Worst Nobel Prize Awarded

Portuguese neurologist Antonio Egas Moniz developed a surgical procedure that was successful in advancing mental health, according to his peers. Although adopted by neuro-scientists, surgeons and scientists around the world, it was at its best irreversibly destructive and at its worst inhumane. “And yet, Moniz was awarded the Nobel Prize in Medicine for it,” says SciShow host Michael Aranda. “It’s quite possibly the most regrettable Nobel Prize ever awarded, because Moniz was given the prize for developing lobotomy.” Tune in as Aranda digs into the details.

How Many Dino Fossils Exist?

Has the age of dinosaur-fossil discovery passed us by. Not quite, say paleontologists, who are wondering how many species of dinosaurs are there to discover and how many fossils of them are out there.

Host Michael Aranda says the first dinosaur fossil was discovered in 1824, and over the next 150 years, paleontologists only found an average of one fossil a year. Now we’re finding an average of 15 per year. Aranda says that paleontologists calculate that between 2069 and 2102 we will have found 75 percent of the dinosaur genera, and by the mid-22nd century, 90 percent.

Tune in as Aranda explains in this edition of SciShow.

Dating Dead Things

Ever wonder how scientists date prehistoric fossils, or younger things such as dead trees? The answer is radiocarbon dating, including an advanced method known as advanced mass spectometry which has been used since the late 1970s. Host Michael Aranda explains in this edition of SciShow.
