The molecular building blocks that make up DNA absorb ultraviolet light so strongly that sunlight should deactivate them -- yet it does not. Now scientists have made detailed observations of a 'relaxation response' that protects these molecules, and the genetic information they encode, from UV ...
Scientists turned thymine into a gas and hit it with two pulses of light in rapid succession: first UV, to trigger the protective relaxation response, and then X-rays, to detect and measure the response. "As soon as the thymine swallows the light, the energy is funneled as quickly as po...
I’m basically an explorer. Even if exploration doesn’t come naturally to you, I believe scientists of every temperament can learn to explore. I'd like to help everyone here become more creative, more open to oppo...
Are X-Rays Bad for You? X-rays are a wonderful addition to the world of medicine; they let doctors peer inside a patient without any surgery at all. It's much easier and safer to look at a broken bone using X-rays than it is to open a patient up. But X-rays can also be harmf...
By definition, you can't reason your way to anything really new, so you must journey into the unknown. 翻译: 如果你想发现新的事物,千里之行的第一步就是要学会与不确定性共存,并学会接受失败如常,因为寻找未知事物的风险就像成为一名从不系安全绳的高空杂技演员一样大。
“Bitewing” x-rays – Why are they used to search for decay? The film shown here is the same radiograph as above. In dental terminology, it’s referred to as a “bitewing” x-ray. This is the standard type of image that’s used to look for cavities. ...

How to X-Ray: So you wanna learn how to x-ray? Well then do I have some information for you! Preface: Why did I write this instructable? Well, to have a shot at winning that objet 3D printer! And why would I want that? To set up a hacker
Through experiments involving X-rays and chemicals, they discovered that stem cells were more sensitive to DNA damage compared to other cells.When DNA damage occurs, the cells have the capacity to detect it and cause programmed cells to die, preventing the propagation of the damaged genetic code...
