I know when I used to chemically straighten mine, I did it because I wasn't comfortable with my natural hair. I thought it was too poofy, too kinky. So for me, personally, when I started wearing it natural, it felt like I was blossoming because I was letting go of all the dead hair and all the parts of me that had rejected my natural state.

Biochemistry is the science of life. All our life processes - walking, talking, moving, feeding - are essentially chemical reactions. So biochemistry is actually the chemistry of life, and it's supremely interesting.

My dad is a chemical engineer, and my mom was a teacher. They were pretty serious about education, but I always thought about things a little bit differently.

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'm not the first to admit that raising a child in Park Slope, Brooklyn, can bear an embarrassing resemblance to the TV show 'Portlandia.' My wife and I try to have some ironic distance from the culture of organic, chemical-free parenting, but we're often participants.

Although every step must be taken to protect against a chemical or biological attack in America, our nation would survive the use of those weapons as we did when anthrax was mailed to our Capitol and other targets.

The sheer number of legendary narratives and historically verifiable incidents invites us to revise assumptions about the origins of biological and chemical warfare and its moral and technological constraints.

Carbon-carbon bond formation reactions are important processes in chemistry because they provide key steps in building complex, bio-active molecules developed as medicines and agrochemicals.

The reason there's so many gay people now is because it's a chemical warfare operation, and I have the government documents where they said they're going to encourage homosexuality with chemicals so that people don't have children.

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.

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.

Patents are like fertilizer. Applied wisely and sparingly, they can increase growth. But if you apply too many chemicals, or make patents too strong, then you can leach the land, making growth more difficult.

Even when they are saturated in the sense of the older theory of valence, the elementary atoms still possess sufficient chemical affinity to bind other seemingly also saturated atoms and groups of atoms, under generation of clearly defined atomic bonds.

You don't want flame to hit your food. Flame is bad. Flame does nasty things to food. It makes soot and it makes deposits of various chemicals that are not too good for us. The last thing you really want to see licking at your food while it's on a grill is an actual flame.

Without the EPA and the national pollution safeguards it enforces, more children would have asthma. Our water would be less safe. More chemicals would poison our bodies. And more people would die prematurely from respiratory diseases and heart attacks.

We are working to understand and regulate per- and polyfluoroalkyl synthetic chemicals, known as PFAS and PFOS, used to make water-repellent fabrics and non-stick products. These chemicals have been in prevalent use since the 1940s, but we need to learn more about their potential effects on human health and the environment.

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!

Personally, I think that for example the chemical directive in its present form does too much damage to the chemical industry - especially the medium sized businesses - and will hurt our worldwide competitiveness.

I just think we need to find a way, because we don't dispose of them very well; they have very bad chemicals in them. If we could just find a way, maybe start at a small step with eliminating batteries perhaps in small electronic devices, and then possibly in the future go bigger, that would be great.

I think it's brain chemistry. I'm a positive, cheerful person, and I think it is absolutely the luck of the draw. I think the life I have had has come largely from the chemicals in my head. I see my life as good, and I think, a lot of times, if you see your life as good, then that's how it turns out.

We need the UN, to deal with the threats to our common security from nuclear, chemical and biological weapons, not only in the case of Iraq. They must be tackled by the international community together, by strengthening conventions, treaties and agreements.

Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.

But it was soon ascertained that this quaternary matter of the animal body was chemically the same in the plant, was elaborated there, and only appropriated by the animal.

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.
