Those tiny balls of boutique mozzarella cheese with the sticker-shock price tag beckoning from the dairy case — are they the real deal, mozzarella di Bufala Campana DOP, crafted from the milk of water buffaloes? Or are they really cheap fakes made from cow’s milk? A new method described in ACS’ Journal of Agricultural and Food Chemistry promises to provide the answer…

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

Chewing betel quid — the fourth most popular psychoactive substance in the world after tobacco, alcohol and caffeine — exposes its 600 million users to substances that act as direct carcinogens in the mouth, scientists are reporting in a new study. It appears in ACS’ journal Chemical Research in Toxicology

Carbon dioxide (CO2) released into the oceans as a result of water pollution by nutrients — a major source of this greenhouse gas that gets little public attention — is enhancing the unwanted changes in ocean acidity due to atmospheric increases in CO2. The changes may already be impacting commercial fish and shellfish populations, according to new data and…

About the Weekly PressPac

The ACS Weekly PressPac consists of summaries of research published in the American Chemical Society’s more than 40 peer-reviewed journals and its weekly newsmagazine, Chemical & Engineering News. ACS journals publish more than 35,000 articles annually. Although not traditional press releases, PressPac content can be used to prepare news stories and also can be an excellent resource for features and background.

  • C&EN Video Spotlight: Reversible, Light-Activated Anesthetic
    A team of chemists and physicians, led by Dirk Trauner of the University of Munich and Erwin Sigel of Switzerland’s University of Bern, is reporting a new molecule that works like a general anesthetic in the dark, but turns off instantly with a flash of light. Tadpoles exposed to the molecule “go under,” but start swimming instantly when scientists hold a blue-violet light up to their tank. The molecule is not for use in hospitals, however. But Ivan Dmochowski, a researcher at the University of Pennsylvania who wasn’t involved with the study, thinks the molecule might help researchers figure out how general anesthetics work, something that's been a mystery for over 100 years. Watch the video.
  • Must-reads from C&EN: : A Boost for the Fabled “Carbon Clock”
    Carbon-14 dating is essential to scientific fields ranging from global climate change to archaeology. Now a new discovery may improve the accuracy of this mainstay technology in dating materials for periods between 12,000 and 52,800 years ago. For the full story, contact newsroom@acs.org.

ACS Videos

The American Chemical Society encourages news organizations, museums, educational organizations, and other web sites to embed links to these videos.

Spellbound: How Kids Became Scientists
The road to a Nobel Prize began for one scientist in elementary school when his father placed a sign on his bedroom door proclaiming him to be a “doctor.” This is just one of the many experiences that helped launch the careers of scientists from diverse backgrounds who are featured in a new ACS video series called Spellbound: How Kids Became Scientists.

Prized Science video series
Prized Science: How the Science Behind ACS Awards Impacts Your Life
video series is new for 2012! The first episode features the research of Dr. Robert Langer, winner of the 2012 ACS Priestley Medal. He is a professor at the Massachusetts Institute of Technology. The Priestley Medal is the highest honor of the ACS, and it recognizes Langer’s pioneering work making body tissues in the lab by growing cells on special pieces of plastic. Langer’s team has used the approach to make skin for burn patients, for instance, with the goal of eventually making whole organs for transplantation. The second episode features Dr. Chad Mirkin, winner of the 2012 ACS Award for Creative Invention. His research has provided patients with faster diagnoses for influenza and other respiratory infections, and new tests that improve care for heart disease. More episodes will appear later in the year. The series is available at the Prized Science website and on DVD by email request.

The Periodic Table Table Featuring Theo Gray
Some people collect stamps. Wolfram Research co-founder and author Theo Gray collects elements. Step into his office, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells and hundreds of other chemical artifacts. But his real DIY masterpiece is the world's first "periodic table table.” Within this masterfully constructed table-top lay samples of nearly every element known to man, minus the super-radioactive ones.

Healing the voice: Synthetic vocal cords
Synthetic vocal cords
may someday heal the voices of singers like Julie Andrews — whose legendary voice was permanently damaged in a 1997 operation. Filmed in the lab of 2012 ACS Priestley Medalist and MIT Institute Professor Robert Langer, our latest video explains how artificial polymer vocal cords may help repair damaged vocal tissue
