President Franklin Delano Roosevelt led the United States through the Great Depression and the Second World War, winning four consecutive elections despite the fact that he was believed to have suffered from polio, aka infantile paralysis. His reliance on wheelchairs and other assistance to get around was something that his opponents thought would make him […]

May I introduce you to Min Chiu Li, a Chinese-American scientist to whom many of us owe our lives or the lives of loved ones? In the 1950s, Li figured out a critical aspect about how the disease cancer works, leading to the successful employment of chemotherapy.Min Chiu Li came to the United States to

In the remote grassy highlands of northern Ireland is the Sacred Heart Roman Catholic Church. There, three disprate landmarks – a cross, a grave, and some special dirt – tell a story about hope for an end to suffering.From the Medieval past, the tenth-century Boho High Cross depicts scenes from the Biblical Book of Genesis

Reading about the way the cigarette industry insidiously and effectively played the American public is like watching a horror movie. By now we all (I hope) know how major tobacco companies secretly designed strategies to hide information about the links between smoking and cancer, but reviewing the advertisements and internal corporate documents is like looking

There are two common denominators of the three scientists featured in this image. First, Anthony Fauci, Harold Varmus, and J. Michael Bishop spent decades of their lives devoted to searching for elusive causes and treatment of disease. Fauci worked on HIV among other illnesses, and Varmus and Bishop on cancer (the pair won the Nobel

This picture is neither a coffee stain nor a bad tattoo, but rather a fossil from one of the most important places that evolutionary scientists study the emergence of complex life: the fossils of Burgess Shale in British Columbia.Burgess Shale fossils date from the period of the Cambrian Explosion (525-505 million years ago), when “all

Evolution brings a sense of humility like nothing else can. Ladies and gentlemen, may I introduce you to our ancestors? Featured on the first slide is “Kimberella,” probably the oldest of the “protostome” fossils, dating 255 million years ago – from before the pre-Cambrian explosion.“Aha,” you might be thinking. “That doesn’t look like even the

Here is a picture of two of the most famous hands in art history, and they go along with a not-very-famous but super important story about how human hands evolved.“Nature does not invent very often completely from scratch,” writes evolutionary biologist Sean B. Carroll, “rather, it remodels its existing structures with took kit genes that

“The difference in mind between man and the higher animals, great as it is, is one of degree and not of kind,” wrote Charles Darwin, in his famous _The Descent of Man_ in 1871. And evolutionary biologists still agree. So then what makes the mental capacities of Homo Sapiens and other hominid apes so different?Two

Wanna know the difference between this kid and a chimpanzee? So do evolutionary biologists . . . And with the use of genetic studies, scientists recently have figured out two additional ways that we Homo Sapiens differ from our common primate chimp ancestors from six to eight million years ago. They have to do with

You are looking at a rare Medieval illustration of the anatomy of a uterus. It is highly schematic/abstract, obviously, but the important bits for Medieval people were all there. At the top, you see a fetus (the Latin words used were “embryo,” “conceptus,” and “fetus”), and straight below it is the entrance marked “hec eat

Evolutionary history is the focus of my posts for a while, and what better place to start than CRISPR? Last week, Emmanuelle Charpentier and Jennifer Doudna’s work in using CRISPR for gene editing made news headlines – this is the first time the Nobel Prize in Chemistry has been awarded to two women. The future

This is St. George Jackson Mivart, and he ruffled the feathers of proponents of every side of the evolution debates of the 19th century. The second slide is a fossil of a ancient species called Archaeopteryx, and its ruffled feathers were at the center of evolutionary debates of the 19th century.Mivart was raised Anglican but

Meet Julia Barlow Platt (1857-1935), who in her 70s was elected as the first female mayor of Pacific Grove, California. She spent her late years galvanizing efforts to create a nature preserve on Monterey Bay, which is still one of the most lovely areas on California’s northern coast. Behind these achievements, however, is a story

This is Marie-Claire King (born 1946), and just reading about her accomplishments makes me tired. Besides earning her Ph.D. from UC Berkeley, she has six other honorary doctorates in science from the most prestigious universities in the world. From her work in discovering the genetic foundations of breast cancer, schizophrenia, and hearing loss, to her

A few days ago I did a post featuring a fossil of a creature called Archaeopteryx, famed for having traits both bird- and dinosaur- like: it filled in a gap in the evolutionary record. The photo you see here is of the paleo-biologist Neil Shubin with a model of a creature whose fossils he found.

Historians are frequently enchanted by things discarded as useless by the general public. But I think anyone interested in evolution would find the study of non-gene coding DNA fascinating, including the scientist featured here. This is Susumu Ohno, one of the United States’ foremost geneticists and evolutionary biologists, and he came up with the term

“The Persistence of Memory” is one of artist Salvador Dali’s most recognizable paintings. The surrealist style is perfectly adapted to depicting the ways our minds preserve our memories — they are suggestive, dreamlike, warpable. For however imperfect or relativistic our memories might be, we owe them for much of our sense of identity.How we humans

Charles Darwin’s idea of Natural Selection as the key driver of evolution has been demonstrated many times over. However, in the century and a half since his lifetime, scientists have added onto his theories as various scientific discoveries have been made. Perhaps no one has reframed the picture of Darwinian evolution as much as the

In the early 20th century, science was trendy. Unfortunately, so was bigotry, and the eugenics movement took advantage of the scientific-sounding language of genetics to promote the idea that certain types of people (pretty much white, native-born, able-bodied, and Protestant) needed to propagate for the greater good of humanity. Enter the “Fitter Family Contests” held
