Here is a description of your company. Proin ex id consectetur lobortis. Aliquam, velit vel faucibus dapibus, augue justo ullamcorper turpis, nec convallis metus nunc vel turpis.
Looking at the list of common risk factors, you can easily see how a modern lifestyle can increase a person’s risk of having heart disease. On average, people eat more, smoke more, and walk less than our ancestors. But if heart disease was simply a product of our modern lifestyle, why do so many mummies have it?
The ocean is a turbulent place that isn’t particularly hospitable to humans, so it may seem like the last place you’d expect to learn about human biology.
When we think about what it means to live a healthy life, there are certain truths we take for granted.
On his first day as St. Luke’s Hospital’s first black resident physician, Dr. Bowman made a statement that would set the tone for the rest of his career.
Using his knowledge of physics, Dr. Branson made significant contributions to our understanding of diseases like sickle cell anemia.
Dr. Har Gobind Khorana, who was instrumental in deciphering the genetic code that’s written in our DNA. He was a modest but exceptionally important scientist whose work forever changed science and the world at large.
Put simply, Dr. Li is someone in the world of science you should definitely know.
It’s an unfortunate reality that science is often viewed as being separate and independent from art. Despite their differences, the two find common ground in their ability to uncover beauty in nature. This commonality shines through in the amazing work of Dr. Susumu Ohno.
It's fascinating to learn how we once struggled to understand genetic concepts that we now consider foundational. Counting is a good example. Dr. Joe Hin Tjio showed the world how to accurately count chromosomes and set the stage for numerous medical advancements.
Those who knew Dr. Cavalli-Sforza describe him as an incredibly impactful mentor, a positive personality, and perhaps one of the most influential scientists of the 20th century. He inspired people to take an interest in population genetics and understand how human diversity came to be.
Dr. May Edward Chinn was many things: A high school dropout, a talented and successful pianist, the first African-American woman to graduate from Bellevue Hospital Medical College, and, above all else, a dedicated and compassionate physician. Put simply, Dr. Chinn was an inspiring scientist.
One becomes two, two becomes four, and before long, there are trillions of cells. It’s an awe-inspiring process to learn about embryonic development—cells dividing, moving, and morphing in what looks to be a highly coordinated and complex process. We know this thanks, in part, to researchers like Dr. Reddick.
There are some truly amazing people in history—those who faced unimaginable adversity and still defied all the odds to do world-changing things. Dr. Cecile Hoover Edwards is one such person.
Who was Dr. Percy Lavon Julian? Percy Julian was an African-American research chemist who came to be recognized as one of the greatest chemists of the 1900s.
Protruding from the desolate landscape are the world’s oldest trees—bristlecone pine trees—at least one of which is more than 5,000 years old. Few things on Earth have transcended time like this. But buried in the recesses of our cells sits a biomolecular code that’s been around for much, much longer: DNA.
In its most superficial viewing, our ancestry can seem pretty straightforward, like the sun’s combined light. But, when we look a little harder, you find that everyone’s genetic history is a rich tapestry of different peoples and cultures.
Genetic studies have found signs of a mysterious human group that coexisted with early Homo sapiens in Africa and left a genetic signature that’s persisted in the DNA of modern Africans. Find out more about ancient humans in Africa and what geneticists are studying.
Imagine for a moment that 20 people were sent from earth to establish a human colony on Mars. From these people, a new society would have to be formed.
Once a species goes extinct, that’s it—there’s no coming back. So went the mighty Tyrannosaurus rex, the towering woolly mammoth, and the famed passenger pigeon. But, then again, what if extinction isn’t so permanent? What if these creatures are only mostly extinct?
What if we want to know what life was like before written text, before the beginning of modern oral history? How can we see the world that existed more than 50,000 years ago? For this, we turn to the stories contained within our DNA.
