I Origins Went To Insane Lengths To Get Its Science Right

Mike Cahill's new movie I Origins, out tomorrow, is about a molecular biologist studying the evolution of the human eye. And Cahill tells io9 he was absolutely determined to get the science right — not just having scientific advisers, but giving them headphones and planting them in front of monitors on set. » 7/17/14 10:39am 7/17/14 10:39am

New Double Helix Visualization Revises What We Know About DNA

By using an advanced microscopy technique, researchers have collected the most precise measurements to date of DNA's tangled structure. Their results showed significant variations to the well-known double helix — variations that are offering fresh insights into the inner workings of this life-bearing molecule. » 5/16/14 3:20pm 5/16/14 3:20pm

New research suggests women can make sperm, and men can make eggs

What started as an investigation into developmental mouse biology has become a lot more than that. Biologist Katsuhiko Hayashi discovered a way to turn mouse skin cells into sperm and egg cells — and actually used these modified cells to create a living baby mouse. The question is, can it work in humans? » 8/21/13 4:26pm 8/21/13 4:26pm

How do you make eggs out of plants? (And why?)

As food science and our understanding plant proteins expands by leafs and stems, some food-thinking entrepreneurs are looking for ways to make our agricultural products safer, more environmentally sustainable, more humane, and yes, cheaper. Recently, I paid a visit to food science startup Hampton Creek Foods to learn… » 4/07/13 7:00am 4/07/13 7:00am

Think your sex life is complicated? Imagine having 7 sexes.

No, this isn't something out of an Octavia Butler novel. It’s Tetrahymena thermophila — a single-celled organism that goes way beyond male and female. It has seven different sexes to choose from. Now a new study published in PLOS has finally made sense of its bizarrely complex and seemingly random sex life. » 3/27/13 2:30pm 3/27/13 2:30pm

The Shark Immunity Factor that Could Save Your Life

Scientists have known for some time that dogfish sharks, like the one pictured up top, naturally produce a broad-spectrum antibiotic called squalamine in their livers. Now, new research into the cellular function of squalamine reveals how it also confers a broad-spectrum antiviral benefit for the shark — one we humans… » 9/20/11 12:58pm 9/20/11 12:58pm

What makes your cells self-destruct from too much fat and sugar?

One of the built-in defense mechanisms of our cells is that they self destruct when overloaded with fat and sugar. This helps kill off damaged cells, and prevents them from multiplying into cancers. While this ability is crucial for the body to maintain itself, up until now we've never known what causes this… » 7/08/11 5:51pm 7/08/11 5:51pm

One of the fathers of nuclear weapons wrote science fiction about…

Leo Szilárd was one of the first scientists to come up with the idea of a nuclear chain reaction, and he wrote the 1939 letter (signed by his friend Albert Einstein) that convinced President Roosevelt to launch the Manhattan Project. After the war, though, he turned his attention to molecular biology — and to spur… » 3/04/11 7:30am 3/04/11 7:30am
