Biology is exciting and informative

Biology is exciting and informative, giving us insight into the beauty of life. What we see with the microscope is the amazing developmental process by which form emerges out of unformed material. To watch an embryo develop is to see the life of a new individual emerge, gradually, stage by stage, from very simple material […]

The Spiral

Here’s a personal view about body symmetry and body openings from someone who lived through the evolution of bilateral symmetry. Form? I didn’t have any; that is, I didn’t know I had one, or rather I didn’t know you could have one. I grew more or less on all sides, at random; if this is […]

The tardibot

I work with fascinating creatures. Bryozoans, brachiopods, nemerteans, priapulids, echinoderms, acoelomorphs, among others! However, despite their splendor, they are little known. Perhaps because they are small or because they are difficult to find, they remain anonymous among the public. But their charisma is so strong that from time to time one or another ends up […]

A galaxy for insight

By empowering readers and observers with transparent access to the means by which conclusions are reached, rather than assembling them in an audience to hear the Authorities deliver the catechism from on high, we are all of us becoming scientists in this way, entering into a democracy of the intellect that is already bearing spectacular […]

A bicycle for the mind

[The bike is] one of the great force amplifiers of all time because it doesn’t detract from us–it takes everything we’ve got and amplifies it. Most computers today are sold like cars, whereas many things as possible are done for you. You don’t have to understand how it works and, in fact, you don’t have […]

Gastrulation

It was, Lewis Wolpert admits, a rather pretentious thing to say. The renowned biologist and author was at a European scientific meeting with colleagues when a doctor delegate asked him what he was researching. Gastrulation, Wolpert replied. The doctor’s declaration of ignorance was briskly met with: “It is not birth, marriage, or death, but gastrulation […]
