A potential new energy source so controversial that people once regarded it as junk science is moving closer to acceptance by the mainstream scientific community. That’s the conclusion of the organizer of one of the largest scientific sessions on the topic — “cold fusion” — being held here for the next two days in the Moscone Center during the 239th National Meeting of the American Chemical Society...

Chemistry’s often-overlooked role in fostering sustainability goes on parade this week with one of the largest and most comprehensive series of scientific reports on advances toward that goal and the challenges lying ahead. The 1,600 reports and other presentations are part of the theme — “Chemistry for a Sustainable World”...

What better venue than San Francisco –– sourdough capital of the world –– to unveil a new natural sourdough ingredient that could replace conventional additives in a variety of other breads, while making them tastier and more healthful? And that’s what scientists described today at the American Chemical Society’s 239th National Meeting. In the study, Maija Tenkanen, Ph.D., and colleagues reported...

Two decades of atomic bomb testing in the atmosphere are yielding an unexpected bonus for consumers, scientists reported here today at the 239th National Meeting of the American Chemical Society (ACS). It’s a new test to determine whether that Bordeaux or burgundy is from a fine vintage year and commands premium price or actually is a counterfeit vin ordinaire or cheap plonk worth much less. Graham Jones, Ph.D., who headed the research...

With stomach irritation preventing almost 2 out of every 10 people from enjoying coffee, scientists today reported discovery of several substances that may be among the culprits responsible for brewing up heartburn and stomach pain in every cup. Their report, presented here at the 239th National Meeting of the American Chemical Society, included the counter-intuitive finding that espresso, French...

A new simple, inexpensive three-in-one test to diagnose a terrible trio of parasitic diseases that wreak havoc in the developing world is passing preliminary tests, scientists reported here today. Described during the 239th National Meeting of the American Chemical Society the test is for Chagas’ disease, leishmaniasis, and “sleeping sickness” or African trypanosomiasis. This year will see about 800,000...

Scientists today reported the development of a “smart” roof coating, made from waste cooking oil from fast food restaurants, that can “read” a thermometer. The coating automatically switches roles, reflecting or transmitting solar heat, when the outdoor temperature crosses a preset point that can be tuned to the local climate. They described the coating at the 239th National Meeting of the American...

The process that lights up big-screen plasma TV displays is getting a new life in producing ultra-clean fuels, according to a report here today at the 239th National Meeting of the American Chemical Society (ACS). It described a small, low-tech, inexpensive device called a GlidArc reactor that uses electrically-charged clouds of gas called “plasmas” to produce in three steps super-clean fuels from waste materials. One is a diesel fuel that releases...

Cutting back on consumption of meat and dairy products will not have a major impact in combating global warming — despite repeated claims that link diets rich in animal products to production of greenhouse gases. That’s the conclusion of a report presented here today at the 239th National Meeting of the American Chemical Society. Air quality expert Frank Mitloehner, Ph.D., who made the...

Label directions for using some household pesticides are written in a way that may leave consumers with the impression that “if a little is good, more is better,” according to a study presented here today at the 239th National Meeting of the American Chemical Society (ACS). As a result, consumers may use excessive amounts of pesticides that could subject family members and pets to increased...

Scientists in California are reporting for the first time that walnuts — already renowned as a rich source of omega-3 fatty acids that fight heart disease — reduce the size and growth rate of prostate cancer in test animals. They described their findings today at the 239th National Meeting of the American Chemical Society (ACS), being held here this week. “Walnuts should be part of a prostate-healthy...

Scientists today described a new ultra-rapid acting mealtime insulin (AFREZZA™) that is orally inhaled for absorption via the lung. Because the insulin is absorbed so rapidly, AFREZZA’s profile closely mimics the normal early insulin response seen in healthy individuals. AFREZZA is awaiting approval by the U. S. Food and Drug Administration (FDA). This presentation took place at the 239th American...

Scientists today reported development of a new method for converting soybean oil into a highly effective bio-based sunscreen active ingredient that does not carry the potential health concerns of ingredients in some existing sunscreens. The new, natural sunscreen agent could replace petroleum-derived ingredients in a variety of personal-care products, they reported at the 239th National Meeting of the American Chemical Society (ACS) being held...

The plant that gave the world tequila contains a substance that seems ideal for use in a new genre of processed foods -- so-called “functional foods” -- with health benefits over and above serving as a source of nutrients, scientists reported here today at the 239th National Meeting of the American Chemical Society (ACS). Foods spiked with “fructans” from the agave plant may help protect against osteoporosis...

Scientists today reported development of the first two-in-one test that can simultaneously detect both the E. coli bacteria responsible for terrible food poisoning outbreaks, and the toxins, or poisons, that the bacteria uses to cause nausea, vomiting, diarrhea and other symptoms in its victims. They described it at the 239th National Meeting of the American Chemical Society (ACS), being held here this...

Queso fresco, a quintessential ingredient in Mexican cuisine, would retain higher quality in supermarket display cases if stored at a lower temperature. That’s the conclusion of a report presented here today at the 239th National Meeting of the American Chemical Society. “The increasing popularity of Hispanic food in the US is causing attention to be focused on the chemistry of these products for the first...

Scientists today reported widespread global contamination of sea sand and sea water with the endocrine disruptor bisphenol A (BPA), and said that the BPA probably originated from a surprising source: Hard plastic trash discarded in the oceans and the epoxy plastic paint used to seal the hulls of ships. “We were quite surprised to find that polycarbonate plastic biodegrades in the environment,” said Katsuhiko...

Scientists today described the discovery of a new drug, which is currently in Phase II clinical trials, designed to specifically target the root cause of painful menstrual cramps, not just the symptoms. The condition, called dysmenorrhea, is the leading cause of absenteeism from school and work among women in their teens and 20s. The scientists described the study at the American Chemical Society (ACS) 239th...

A study of the brains of people who stayed mentally sharp into their 80s and beyond challenges the notion that brain changes linked to mental decline and Alzheimer’s disease are a normal, inevitable part of aging. In a presentation here today at the 239th National Meeting of the American Chemical Society (ACS), Changiz Geula, Ph.D. and colleagues described their discovery of elderly people with super-sharp memory — so-called “super...

As you stroll down restaurant row and catch the wonderful aroma of food — steaks, burgers, and grilled veggies — keep this in mind: You may be in an air pollution zone. Scientists in Minnesota are reporting that commercial cooking is a surprisingly large source of a range of air pollutants that could pose risks to human health and the environment. They discussed the topic here today at the 239th National Meeting...

Scientists today described development of a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage. Reporting at the 239th National Meeting of the American Chemical Society (ACS), they said it could allow scientific analysis of hundreds of artifacts that until now were off limits because museums and private collectors did not want the objects damaged...
