First synthesis of gold nanoparticles inside human hair for dyeing and much more

In a discovery with applications ranging from hair dyeing to electronic sensors to development of materials with improved properties, scientists are reporting the first synthesis of gold nanoparticles inside human hairs. Their study appears in ACS’ journal Nano Letters.

New method for uncovering side effects before a drug hits the market

Side effects are a major reason that drugs are taken off the market and a major reason why patients stop taking their medications, but scientists are now reporting the development of a new way to predict those adverse reactions ahead of time. The report on the method, which could save patients from severe side effects and save drug companies time and money, appears in ACS’ Journal of Chemical Information and Modeling.

Toward reducing the greenhouse gas emissions of the Internet and telecommunications

Amid growing concern over the surprisingly large amount of greenhouse gas produced by the Internet and other telecommunications activities, researchers are reporting new models of emissions and energy consumption that could help reduce their carbon footprint. Their report appears in ACS’ journal Environmental Science & Technology.

Nature-inspired advance for treating sensitive teeth

Taking inspiration from Mother Nature, scientists are reporting an advance toward preventing the tooth sensitivity that affects millions of people around the world. Their report on development of the substance, similar to the adhesive that mussels use to attach to rocks and other surfaces in water, appears in the journal ACS Applied Materials & Interfaces.

Wine and tea are key ingredients in South African plan to grow domestic research

The South African government is investing in scientific research to foster production of agricultural products like pinotage (the country’s signature red wine) and honeybush (source of a tea so fragrant that a potful can perfume an entire house) to create jobs and boost the economy. That effort and others aimed at developing a globally competitive research enterprise are the topics of cover stories in the current issue of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.

Hagfish slime as a model for tomorrow’s natural fabrics

Nylon, Kevlar and other synthetic fabrics: Step aside. If new scientific research pans out, people may be sporting shirts, blouses and other garments made from fibers modeled after those in the icky, super-strong slime from a creature called the hagfish. The study appears in ACS’ journal Biomacromolecules.

Sustainable way to make a prized fragrance ingredient

Bacteria could make a sustainable alternative to a prized natural ingredient in many perfumes.

A new, super-nutritious puffed rice for breakfast cereals and snacks

A new way to blow up grains could make a form of puffed rice loaded with protein and other nutrients.

Toward a pill to enable celiac patients to eat foods containing gluten

Scientists are reporting an advance toward development of a pill that could become celiac disease’s counterpart to the lactase pills that people with lactose intolerance can take to eat dairy products without risking digestive upsets. They describe the approach, which involves an enzyme that breaks down the gluten that causes celiac symptoms, in the Journal of the American Chemical Society.

The Chemistry of Snowflakes

WASHINGTON, — For everyone with holiday visions of snowflakes dancing in their heads, the American Chemical Society (ACS), the world’s largest scientific society, today issued a video explaining how dust, water, cold and air currents collaborate to form these symbols of the season. It’s all there in an episode of Bytesize Science, the award-winning video series produced by the ACS Office of Public Affairs at www.BytesizeScience.com.

The chemistry of early photographs: New American Chemical Society video

WASHINGTON, — The chemistry of early photography comes under the lens in a new episode of Bytesize Science, the American Chemical Society (ACS) award-winning video series. Produced by the ACS Office of Public Affairs, it is available at www.BytesizeScience.com.

Speed limits on cargo ships could reduce their pollutants by more than half

Putting a speed limit on cargo ships as they sail near ports and coastlines could cut their emission of air pollutants by up to 70 percent, reducing the impact of marine shipping on Earth’s climate and human health, scientists have found. Their evaluation of the impact of vessel speed reduction policies, such as those proposed by the California Air Resources board, appears in ACS’ journal Environmental Science & Technology.

Plastics used in some medical devices break down in a previously unrecognized way

Scientists have discovered a previously unrecognized way that degradation can occur in silicone-urethane plastics that are often considered for use in medical devices. Their study, published in ACS' journal Macromolecules, could have implications for device manufacturers considering use of these plastics in the design of some implantable devices, including cardiac defibrillation leads.

Advice for bag-in-box wine drinkers: Keep it cool

Bag-in-box wines are more likely than their bottled counterparts to develop unpleasant flavors, aromas and colors when stored at warm temperatures, a new study has found. Published in ACS' Journal of Agricultural and Food Chemistry, it emphasizes the importance of storing these popular, economical vintages at cool temperatures.

U.N. meeting this week to extend greenhouse gas treaty

Amid concern about the possible role of climate change in the development of Hurricane Sandy and other severe weather, negotiators from around the world will gather at a United Nations meeting this week and next to extend an expiring agreement aimed at reducing greenhouse gases. That effort is the subject of a story in the current edition of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.

New advance could help soldiers, athletes, others rebound from traumatic brain injuries

A potential new treatment for traumatic brain injury (TBI), which affects thousands of soldiers, auto accident victims, athletes and others each year, has shown promise in laboratory research, scientists are reporting. TBI can occur in individuals who experience a violent blow to the head that makes the brain collide with the inside of the skull, a gunshot injury or exposure to a nearby explosion. The report on TBI, which currently cannot be treated and may result in permanent brain damage or death, appears in the journal ACS Nano.

Scientists sniff out the substances behind the aroma in the “king of fruits”

The latest effort to decipher the unique aroma signature of the durian — revered as the “king of fruits” in southeast Asia but reviled elsewhere as the world’s foulest smelling food — has uncovered several new substances that contribute to the fragrance. The research appears in ACS’ Journal of Agricultural and Food Chemistry.

Many home couches contain potentially toxic flame retardants

Scientists are reporting an increasing use of flame retardants in the main gathering spot for adults, children and family pets in the home — the couch. In a study published in ACS’ journal Environmental Science & Technology, they describe the first efforts to detect and identify the flame retardants applied to the foam inside couches found in millions of family rooms and living rooms across the U.S.
