Can genetics tell us if dog behavior really varies by breed?
Dogs have been in our lives for at least 10,000 years. At first, dogs did not look like today’s common breeds — these appeared only…
Antibiotic-resistant bacteria are way older than penicillin
Remember the classic chases where Wile E. Coyote tries to catch Roadrunner but is often outsmarted? It turns out that bacteria have to…
Ancient bacteria leave behind fossils, too!
Scientists used genetic technology to identify the different roles of bacteria present in ancient fossil formations called stromatolites.
Salt pools can guide our search for life on other planets
Pink, green, and square-shaped microbes can help us understand the limits of life on Earth and guide our search for life outside the planet.
A software program builds alternative DNA molecules
Scientists are using computer programs to understand our early beginnings. Click on the link to see how they are doing it, and how they…
There may be other ways to build DNA and RNA
One of the most fundamental building blocks of life on earth is DNA. This molecule consists of four base pairs and a negatively charged…
One way that oxygen can damage our DNA
Guanine, a component of DNA, is revealed to react with oxygen and change how your genes are expressed.
Who figured out the structure of DNA?
Today, we know DNA is where we get our traits. We know we inherit our DNA from our parents, and that our DNA contains genes. We know that we…
