Soviet Doctors Cured Infections With Viruses, and Soon Yours Might Too

In the Soviet Union, western antibiotics couldn't make it past the Iron Curtain. So Eastern Bloc doctors figured out how to use viruses to kill infectious bacteria. Now, with antibiotic-resistant bugs vexing doctors, that eerie yet effective method might come our way. In post-antibiotic world, infection cures you! » 6/07/14 4:51pm 6/07/14 4:51pm

Nerve cells may have evolved in animals twice

Ctenophores, also known as the "comb jellies", are an ancient phyla of animals. They have no HOX genes, at least some of which are present in every other animal except themselves and sponges. They lack many of the basic immune system adaptations common to all other animals, including sponges. » 5/27/14 10:16am 5/27/14 10:16am

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

The First Lifeform Capable Of Passing Down A Juiced-Up Version Of DNA

Scientists have engineered the first living microbe that can carry and pass down an expanded genetic code to future generations — one that has six base pairs instead of the usual four. It's a breakthrough that will not only allow us to build powerful new forms of life, it's also changing what we know about evolution. » 5/08/14 8:00am 5/08/14 8:00am

Scientists Can Now Genetically Modify Facial Features

This image is a CT scan of a mouse's face — but not just any mouse. Scientists at Berkeley have identified thousands of small DNA regions responsible for influencing the development of facial features — and they used this insight to modify the faces of embryonic mice. The question now is, are humans next? » 10/28/13 8:00am 10/28/13 8:00am

Yet another lesson that should be banished from biology textbooks

At some point, you probably learned about the idea of dominant and recessive genetic characteristics. A common example is tongue-rolling — those who can do it are said to have a dominant genetic trait. Except that's all wrong. And so are a lot of other things your teacher called dominant traits, too. » 8/26/13 3:53pm 8/26/13 3:53pm
