There's almost no food that isn't genetically modified. Genetic modification is the basis of all evolution. Things change because our planet is subjected to a lot of radiation, which causes DNA damage, which gets repaired, but results in mutations, which create a ready mixture of plants that people can choose from to improve agriculture.
The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C - not much good for defrosting the pizza, let alone cooking it.
Using predictive models from engineering and public health, designers will plan safer, healthier cities that could allow us to survive natural disasters, pandemics, and even a radiation calamity that drives us underground.
In a spiritual sense, a positive attitude may help you get through chemotherapy and surgery and radiation and what have you. But a positive mental attitude does not cure cancer - any more than a negative mental attitude causes cancer.
Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution.
Radiation doesn't recognize borders. A meltdown in Japan or India, say, is a danger to the whole world. Wind circulates the radiation everywhere. Water quality is affected. We all eat the same fish. We use products from all over the world - if something is contaminated, it will cause harm.
Asteroids are deep-space bodies orbiting the Sun, not the Earth, and traveling to one would mean sending humans into solar orbit for the very first time. Facing those challenges of radiation, navigation and life support on a months-long trip millions of miles from home would be a perfect learning journey before a Mars trip.
The campaign finance scandal in America is the global warming of American political life - with cash substituting for deadly solar radiation.
Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.
My discovery that black holes emit radiation raised serious problems of consistency with the rest of physics. I have now resolved these problems, but the answer turned out to be not what I expected.
Only black holes of very low mass would emit a significant amount of radiation.
My experiments proved that the radiation of uranium compounds can be measured with precision under determined conditions and that this radiation is an atomic property of the element of uranium.
While receiving radiation treatment for a thyroid illness, I had refused to take beta-blockers - a medication that would have eased its side effects - because they were deemed illegal by the sport's governing body, the International Association of Athletics Federations.
The life expectancy of people going to Mars may be decreased by the higher level of radiation that they receive.
During my time in orbit, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained my heart. Every day, I was exposed to ten times the radiation of a person on Earth, which will increase my risk of a fatal cancer for the rest of my life.
I am now almost certain that we need more radiation for better health.
I'm taking special treatments for the cancer in my brain and in my liver. Part of the liver was removed, and they did the treatment on four places in my brain with radiation. And now I'm taking a long-term medicine that stimulates my own immune system to fight against cancer.
I'm happy to tell you that having been through surgery and chemotherapy and radiation, breast cancer is officially behind me. I feel absolutely great and I am raring to go.
It is seen that both matter and radiation possess a remarkable duality of character, as they sometimes exhibit the properties of waves, at other times those of particles. Now, it is obvious that a thing cannot be a form of wave motion and composed of particles at the same time - the two concepts are too different.
In the Radiation Laboratory we count it a privilege to do everything we can to assist our medical colleagues in the application of these new tools to the problems of human suffering.
I am a type-2 diabetic, and they took me off medication simply because I ate right and exercised. Diabetes is not like a cancer, where you go in for chemo and radiation. You can change a lot through a basic changing of habits.
People do really well on space missions, but it's the physiological, the medical stuff, the stuff like radiation, loss of bone mass and muscle mass and density. It's those things that we need to figure out.
What these satellites do is they record light radiation that's reflected off the surface of the Earth in different parts of the light spectrum. We use false color imaging to try to tease out these very subtle differences on the ground.
That's a tumor. It goes across my liver, up through my lungs, all the way around my heart. And when they were done trying to cut it out, nuke it out with radiation and chemotherapy it out, it left so much scar tissue that when I walk outside now in cold weather and take a deep breath, it feels like someone is stabbing me.
Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.
In the past, radiation treatment planning has been a very lengthy procedure. Now, with the aid of CT therapy-planning computer programs, we can position the therapy beams automatically with precision in a few minutes.
