Fundamental changes are needed in the education of the scientists whose work impacts medicine, drug discovery, development of sustainable new fuels and other global challenges society is facing in the 21st century. Those changes in graduate education in chemistry are the topic of a special symposium here today at the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.
Peter J. Stang, Ph.D., distinguished professor of chemistry at the University of Utah and editor of the Journal of the American Chemical Society (JACS), has been named winner of the 2013 Priestley Medal by the American Chemical Society (ACS). It is the highest honor bestowed by the world’s largest scientific society.
Cooking an egg may seem like the simplest of culinary arts, but this process remains the topic of a huge controversy among chefs and experts on the chemistry of cooking.

Renowned for its cuisine and chefs and as a global hub of the energy industry, New Orleans this week hosts what news media have described as the “World Series of Science,” one of the year’s largest and most important scientific conferences. The meeting, which begins today and continues through Thursday, happens to have the theme “CHEF,” which stands for “The Chemistry of Energy and Food.”
Scientists at The Scripps Research Institute have illuminated the mechanism at the heart of one of the most useful processes in modern chemistry. A reaction that is robust and easy to perform, it is widely employed to synthesize new pharmaceuticals, biological probes, new materials and other products.
Dark and sleek, it hides beneath the water waiting for prey. A Texas Tech University researcher says the target will never know what hit them because they probably can’t smell the voracious pirate perch.
Even though the concept is important to plant and human physiology, osmosis is understood in biology and chemistry in simple -- and often incorrect -- way.
Tiny versions of the reflectors on sneakers and bicycle fenders that help ensure the safety of runners and bikers at night are moving toward another role in detecting bioterrorism threats and diagnosing everyday infectious diseases, scientists said today.
The most serious ongoing water pollution problem in the Gulf of Mexico originates not from oil rigs, as many people believe, but rainstorms and fields of corn and soybeans a thousand miles away in the Midwest. An expert on that problem — the infamous Gulf of Mexico “Dead Zone” — today called for greater awareness of the connections between rainfall and agriculture in the Midwest and the increasingly severe water quality problems in the gulf.
Already renowned as a healthy treat when enjoyed in moderation, chocolate could become even more salubrious if manufacturers embraced new technology for making “fruit-juice-infused chocolate,” a scientist said here today.

But scientific presentations at a meeting of the world’s largest scientific society this week are focusing on what may be an advance in developing GUMBOS-based materials with far-reaching medical, electronic and other uses.
The search for ways to use megatons of carbon dioxide that may be removed from industrial smokestacks during efforts to curb global warming has led to a process for converting that major greenhouse gas back into the fuel that released it in the first place. Research on the project was a topic here today at the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

In a discovery suggesting that odors may have a far more important role in life than previously believed, scientists have found that heart, blood, lung and other cells in the body have the same receptors for sensing odors that exist in the nose. It opens the door to questions about whether the heart, for instance, “smells” that fresh-brewed cup of coffee or cinnamon bun, according to the research leader, who spoke here today at the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.

One of the Crescent City’s time-honored traditions – a steaming bowl of Yak-a-mein Soup, a.k.a., “Old Sober” — after a night of partying in the French Quarter actually does have a basis in scientific fact. That was the word today from an overview of the chemistry of hangovers, presented as part of the 245th National Meeting & Exposition of the American Chemical Society, the world’s largest scientific society.
A team led by Sean Ekins at Collaborative Drug Discovery in Burlingame, Cal., and Joel Freundlich at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School has trained computers to sift through drug libraries and pick out compounds likely to clobber TB with minimal side effects to humans. They have ‘taught’ the computers to understand which chemical features of a drug are associated with efficacy against TB and which are associated with toxicity to mammalian cells. The process may lead to much less trial and error in finding new therapies. The computers even rediscovered a compound reported 40 years ago to have anti-TB activity but since forgotten.
