A Cool New Theory Explains Why Red Wine Is So Damned Good For You

The antioxidant resveratrol, which is found in red wine and other foods like nuts and soy, is known for its ability to decrease incidence of heart disease and other illnesses, leading some to call it the "elixir of youth." Researchers at the Scripps Research Institute now have an explanation for how it works. » 12/23/14 12:20pm 12/23/14 12:20pm

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

Supercentenarian's Blood Provides Clues To Extending Human Life

Prior to her death at the tender age of 115, Hendrikje van Andel-Schipper was the world's oldest woman. Recently, scientists had the opportunity to study her blood — and what they discovered could have serious implications to the future of rejuvenation therapies. » 4/23/14 2:47pm 4/23/14 2:47pm

British scientists have finally figured out how sperm is able to connect with an egg. The process is facilitated by a molecule dubbed Juno, a protein that allows sperm to dock to the surface of an egg. The discovery could introduce new fertility treatments and birth control. » 4/17/14 1:30pm 4/17/14 1:30pm

Controversial study linking GM corn to tumors in rats retracted

Since its publication in September 2012, a study that showed rats fed Monsanto’s glyphosate-resistant NK603 maize developed more tumors than controls has been roundly criticized for its poor experimental design and dubious statistical methods. Yesterday, the study was retracted. » 11/29/13 8:00am 11/29/13 8:00am

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

Learn the basics of cell biology with these adorable science comics

To help herself study, biology student Biol Jerk draws sweet little comics explaining the differences between the various cells that make up the epidermis, the distinctions between schwann cells and oligodendrocytes, and what the Ran cycle has in common with clubbing. » 12/16/12 7:30am 12/16/12 7:30am

Stunning molecular biology illustrations look like floral abstract art

Molecular biology professor and artist David Goodsell has no trouble finding art in the human body. His hand-drawn watercolor illustrations explode with color while offering his visual interpretation of bacteria, viruses, and human cells. » 7/29/12 2:00pm 7/29/12 2:00pm

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

There's a scientific reason why a pinch of salt makes things sweeter

Ever wonder why salted chocolate and caramel taste even better than unsalted? Or why adding a pinch of salt to cookies makes them sweeter? A group of researchers has found evidence that it's because you have intestinal cells in your taste buds. » 3/08/11 8:00am 3/08/11 8:00am

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

Watch Cells Mutate Into Cancer and Divide Crazily, In These Amazing…

Every day, the cells in your body are dividing like crazy - sometimes too much, which is the definition of cancer. Here you can see breast cancer cells in action, multiplying into what could become a tumorous growth. » 3/31/10 6:02pm 3/31/10 6:02pm

Freeman Dyson Goes Wild

Forever-young physicist Freeman Dyson, now 83, has long been beloved by scifi writers for his extremely fucking cool ideas. He invented the Dyson Sphere, featured in a Star Trek: TNG episode, where the crew visits a sun wrapped entirely in an artificial sphere that captures every bit of solar energy available (you can… » 11/19/07 11:15am 11/19/07 11:15am
