The Environmental Cost of Contact Lenses

American Chemical Society (ACS)

Many people rely on contact lenses to improve their vision. But these sight-correcting devices don’t last forever — some are intended for a single day’s use — and they are eventually disposed of in various ways. Now, scientists are reporting that throwing these lenses down the drain at the end of their use could be contributing to microplastic pollution in waterways.

A Paper Battery Powered by Bacteria

American Chemical Society (ACS)

— In remote areas of the world or in regions with limited resources, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be unavailable or too expensive. New power sources are needed that are low-cost and portable. Today, researchers report a new type of battery –- made of paper and fueled by bacteria --- that could overcome these challenges.

Researcher Develops New Contaminant Detection Technique for Blood Thinner Heparin

University of Rhode Island

In 2008, a contaminant eluded the quality safeguards in the pharmaceutical industry and infiltrated a large portion of the supply of the popular blood thinner heparin, sickening hundreds and killing about 100 in the U.S.

When Sulfur Disappears Without Trace

University of Vienna

Many natural products and drugs feature a so-called dicarbonyl motif – in certain cases however their preparation poses a challenge to organic chemists. In their most recent work, Nuno Maulide and his coworkers from the University of Vienna present a new route for these molecules. They use oxidized sulfur compounds even though sulfur is not included in the final product. The results are now published in the prestigious journal "Science".

Missouri S&T Chemist Rolls the Dice to Better Identify Chiral Molecules in Drugs

Missouri University of Science and Technology

“High risk, high reward” is the kind of discovery Dr. Garry Grubbs seeks with a new experiment designed to rapidly identify the atomic structure of chiral molecules widely used in pharmaceutical drugs. The finding could significantly reduce the time and costs involved in pharmaceutical development and manufacturing.

Taking a Closer Look at Unevenly Charged Biomolecules

American Institute of Physics (AIP)

Clinicians most often monitor antibodies because these small proteins attach to antigens, or foreign substances, we face every day. Most biomolecules, however, have complicated charge characteristics, and the sensor response from conventional carbon nanotube systems can be erratic. A team in Japan recently revealed how these systems work and proposed changes to dramatically improve biomolecule detection. They report their findings in the Journal of Applied Physics.

Common WiFi Can Detect Weapons, Bombs and Chemicals in Bags

Rutgers University-New Brunswick

Ordinary WiFi can easily detect weapons, bombs and explosive chemicals in bags at museums, stadiums, theme parks, schools and other public venues, according to a Rutgers University–New Brunswick-led study. The researchers’ suspicious object detection system is easy to set up, reduces security screening costs and avoids invading privacy such as when screeners open and inspect bags, backpacks and luggage. Traditional screening typically requires high staffing levels and costly specialized equipment.

Simulating Biomolecules Just Got Faster and More Accurate

American Institute of Physics (AIP)

Researchers from the University of Florida and the Federal University of Mato Grosso do Sul in Brazil have used state of the art simulations to assess the effect of both pH and redox potential, or rate of electron transfer, on a biomolecule.
