Contrary to popular belief, crabgrass does not thrive in lawns, gardens and farm fields by simply crowding out other plants. A new study in ACS’ Journal of Agricultural and Food Chemistry has found that the much-despised weed actually produces its own herbicides that kill nearby plants.
Scientists are reporting progress in the search for the first broad-spectrum drugs to combat human rhinoviruses (HRVs), which cause humanity’s most common infectious diseases. Their study on these potential drugs for infections that include the common cold appears in the journal ACS Medicinal Chemistry Letters.
Energy conservation in a small number of households could go a long way to reducing greenhouse gas emissions, scientists are reporting. Their study, which measured differences in energy demands at the household level, appears in the ACS journal Environmental Science & Technology.
New technology offers the promise of reducing billions of dollars of losses that occur each year from the silent, invisible killer of fruits, vegetables and cut flowers — a gas whose effects are familiar to everyone who has seen bananas and other fruit ripen too quickly and rot. That’s the conclusion of an article in the ACS journal Chemical Reviews
Someone finds that piece of chewing gum you pitched today, uses the saliva to sequence your DNA and surreptitiously reads your book of life — including genetic secrets like your susceptibility to diseases. If that scenario, posed in an article in the current edition of Chemical & Engineering News, causes a little discomfort, consider this: That stranger also uses the DNA to reconstruct a copy of y-o-u.
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: Lanthanides Made Easy
The lanthanide elements reside at the bottom of the periodic table. Often called “rare earth elements,” they are essential components of lasers, as well as batteries for hybrid vehicles and iPhones. These elements can have different oxidation states — or hypothetical charges. This affects the properties of the compounds or complexes the element makes. For decades, chemists have believed that it was only possible to make lanthanide complexes in the +3 state. But now, a team at the University of California, Irvine, has overturned that dogma and made +2 complexes. Watch as C&EN Senior Editor Jyllian Kemsley explains the finding and how the complexes are made. Now that chemists know they can make the complexes, they’re eager to find ways to use them.

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.
