The first true antibiotic to be derived from a culture of an actinomyces was isolated in our department in 1940. The organism, Actinomyces antibioticus, yielded a substance which was designated as actinomycin. It was soon crystallized, and its chemical and biological properties were established.
Dad was a chemistry professor at Saint Olaf College in Minnesota, then Oxford College in Minnesota, and a very active member of the American Chemical Society education committee, where he sat on the committee with Linus Pauling, who had authored a very phenomenally important textbook of chemistry.
It's a great disappointment as a leader in the biotech industry that with all the amazing things the drug industry has done in the last couple of decades, we have not made a single major advance, have not not developed a single new chemical entity approved for the treatment for Alzheimer's disease.
When we faced a possibility here in New York of chemical and biological attack, three days after September 11, I called in all of the experts, academic experts, Nobel Prize laureates, and doctors who had dealt with anthrax, doctors who had dealt with various forms of chemical and biological attack.
We often mistake the artificial chemical and psychological thrill of fake edges for the real. In fact we often seek them out as a substitute for the reality of change, growth and exploration. Our minds and bodies help us in this, as they react much the same to this simulations as to the real world.
Never use an aluminum pot, pan, or utensil when cooking tomatoes - or any other soft metal items for that matter. The acidity in the tomato doesn't do well with them; they create a chemical reaction that can turn cooked tomatoes bitter and fade the color, and the food will absorb some of the aluminum!
If you really want to be a good archaeologist, you have to understand ancient DNA; you have to understand chemical analysis to figure out the composition of ancient pots. You have to be able to study human remains. You need to be able to do computer processing and, in some cases, computer programming.
In nerve-free multicellular organisms, the relationships of the cells to each other can only be of a chemical nature. In multicellular organisms with nerve systems, the nerve cells only represent cells like any others, but they have extensions suited to the purpose which they serve, namely the nerves.
Something happens between a novel and its reader which is similar to the process of developing photographs, the way they did it before the digital age. The photograph, as it was printed in the darkroom, became visible bit by bit. As you read your way through a novel, the same chemical process takes place.
Well, I mean, Russia was responsible for shooting down MH17. Russia was responsible for invading Ukraine. Russia is responsible for taking away the chemical weapons in Syria that they didn't take away. Russia was responsible for having honest athletes in the Olympics when they did the whole doping program.
Diet sodas contain a chemical sweetener called Aspartame, which is a potent neurotoxin and endocrine disrupter. Another key ingredient of soft drinks is phosphoric acid, which is added to give it 'bite.' Phosphoric acid is well known to cause tooth rot, bone loss, osteoporosis and gastro intestinal distress.
It was very hard for me to come back to a place of feeling normal about food and about my body. And then, when I came to the other side of it, it felt like something was gone. An exorcism. I still experience the same chemical swings and moods and pain, but I'm much better at dealing with it than I was at 18.
At the height of Iraq's clandestine nuclear weapons program, which nearly succeeded in building a bomb in 1991, Tuwaitha incorporated research reactors, uranium mining and enrichment facilities, chemical engineering plants and an explosives fabrication center to build the device that detonates a nuclear core.
Syria is a signature to the Geneva Protocol of 1925, which bans the use of chemical warfare. Syria has violated that international norm. For the United States to act in response is the right thing to do, is a legitimate thing to do, and is necessary in order to uphold this very important international standard.
I work with the president and speak with him multiple times a week. This is a man, he didn't become the president by accident. And as much as everyone wants to talk about stability, was he unstable when he passed the tax reform? Was he unstable when we finally hit back at Syria and said no more chemical weapons?
The usual way of growing cotton is highly petrochemical-intensive, requiring 110 pounds of nitrogen fertilizer per acre. Some of the fertilizer is broken down by soil bacteria into nitrate, a toxic and highly soluble chemical that can leach into groundwater or get washed into lakes, creating oxygenless dead zones.
I would have thought that if you're going to try to punish the Syrians and prevent them from using chemical weapons again, the thing to do is a one-time strike. Maybe a cruise missile strike at one or two of their air bases just so they know what they're going to gain from using chemical weapons on the battlefield.
Body concentrates order. It continuously self-repairs. Every five days you get a new stomach lining. You get a new liver every two months. Your skin replaces itself every six weeks. Every year, 98 percent of the atoms of your body are replaced. This non-stop chemical replacement, metabolism, is a sure sign of life.
I'm a member of the American Chemical Society, and in its magazine, the 'Chemical and Engineering News,' there was an interview of Vince Gilligan when he had first started the television show 'Breaking Bad.' And in that interview, he was stating how important it was to him that he get the science right for the show.
From the industry's point of view, the problem is not that coal companies blast the top off mountains, turning the area into a moonscape and polluting the air and releasing toxic chemical into what's left of the local streams and aquifers. It's that the people who live near the mines are too cozy with their cousins.
Cancer cells come pre-programmed to execute a well-defined cascade of changes, seemingly designed to facilitate both their enhanced survival and their dissemination through the bloodstream. There is even an air of conspiracy in the way that tumours use chemical signals to create cancer-friendly niches in remote organs.
I grew up in Muenchen where my father has been a professor for pharmaceutic chemistry at the university. He had studied chemistry and medicine, having been a research student in Leipzig with Wilhelm Ostwald, the Nobel Laureate 1909. So I became familiar with the life of a scientist in a chemical laboratory quite early.
In the exodus out of Iraq, we're seeing the effects of just leaving. We left before there was control of chemical weapons stockpiles, without a status-of-forces agreement. We left before the Sunni and Kurds we fought with and fought alongside with were stable, or without empowering them. We left on a political rhetoric.
I believe that the topic of chemical weapons is critically important for international peace and security, and I take note of the ongoing debate over what course of action should be taken by the international community. All those actions should be taken within the framework of the U.N. Charter, as a matter of principle.
Saddam Hussein is a risk-taking aggressor who has attacked four countries, used chemical weapons against his own people, professed a desire to harm the United States and its allies, and, even faced with the prospect of his regime's imminent destruction, has still refused to abide by Security Council demands that he disarm.
Life evolved under conditions of light and darkness, light and then darkness. And so plants and animals developed their own internal clocks so that they would be ready for these changes in light. These are chemical clocks, and they're found in every known being that has two or more cells and in some that only have one cell.
By the end of the millennium, despite the continuing excitement of the field, almost thirty years of a detour from chemistry to medical imaging began to pall, and I changed my focus to a field of chemical research, just in time for my past to catch up with me in the form of a Nobel Prize. All detours should be so productive!
I think it's fun to be superstitious. There's a drama in being superstitious. I'm like that in general. I have friends who don't believe in love or just think it's a chemical thing, and they don't believe in magic. I enjoy believing in all that stuff. It makes things seem more important than they are, like there's more to it.
It has been almost three years since U.S. President Barack Obama pipsqueaked on his chemical-weapons 'red line' in Syria and joined with Russian strongman Vladimir Putin in the pantomime that resulted in the Sept. 27, 2013 U.N. Security Council Resolution 2118, which called on Assad to surrender his chemical weapons stockpile.
The government employs scientists of many varieties in technical capacities, from estimating the environmental toxicity of a chemical to the structural soundness of a bridge. But when it comes to forming policies, these scientists and, especially, behavioral scientists are rarely at the table with the lawyers and the economists.
Cooking is one of the strongest ceremonies for life. When recipes are put together, the kitchen is a chemical laboratory involving air, fire, water and the earth. This is what gives value to humans and elevates their spiritual qualities. If you take a frozen box and stick it in the microwave, you become connected to the factory.
To a synthetic chemist, the complex molecules of nature are as beautiful as any of her other creations. The perception of that beauty depends on the understanding of chemical structures and their transformations, and, as with a treasured work of art, deepens as the subject is studied, perhaps even to a level approaching romance.
We don't need a War on Carbon. We need a new prosperity that can be shared by all while still respecting a multitude of real ecological limits - not just atmospheric gas concentrations, but topsoil depth, water supplies, toxic chemical concentrations, and the health of ecosystems, including the diversity of life they depend upon.
You know what a lima bean does when it's attacked by spider mites? It releases this volatile chemical that goes out into the world and summons another species of mite that comes in and attacks the spider mite, defending the lima bean. So what plants have - while we have consciousness, toolmaking, language, they have biochemistry.
In 2012, General Dempsey, General Petraeus directed the CIA, Secretary Panetta and Secretary Clinton recommended to the president to robustly arm and train the Syrian moderates. He says no. In 2013, conduct a military strike, same national security team, against the Assad regime because he violated the chemical red line. He says no.
People have a good reason to be afraid of tear gas, considering it's a banned agent of war under the 1993 Chemical Weapons Convention. Here's the catch - there's a clause in the treaty that includes an exception for domestic use. Yes, it's illegal for the U.S. military to use tear gas against ISIS, but cool to use against American citizens.
I was educated in the Washington public schools and attended the University of Maryland as a day student, graduating in 1938 with a degree in chemistry. After working for the Dow Chemical Company in Midland, Michigan, for a year, I returned to the University of Maryland to take a Master's degree before going on to Yale to pursue a doctorate.
Syria is important because it lies at the heart of a region critical to U.S. security, a region that is home to friends and partners and one of our closest allies. It is important because the Syrian regime possesses stores of chemical weapons that they have recently used on a large scale and that we cannot allow to fall into terrorists' hands.
