Pharmaceuticals and personal care products

Research has revealed that pharmaceuticals and personal care products can contaminate groundwater, rivers, and sewage, posing significant risks to human health and the environment. Studies have shown that these substances can enter the aquatic food chain, affecting marine life, and are also found in human tissues and breast milk.

Artificial liver moves toward commercialization

Researchers are developing a bioartificial liver that can filter blood toxins and provide temporary support for patients with severe liver failure. The device is being upgraded with freshly isolated pig liver cells and a pulsating bioreactor to improve performance, and the first human clinical trials are scheduled to begin soon.

Foods of the future

Researchers explore biotechnology for healthier foods, enzymes for proper digestion, rapid pathogen detection, and advanced packaging materials. These advancements aim to delay chronic disease, improve mental and physical performance, and enhance food safety.

New findings on origin of life

Scientists report new evidence for the origin of life, including homochirality in meteorite compounds and 1,4-naphthaquinone formed through early solar system chemistry. The discovery may shed light on the start of life on Earth and potentially finding remnants of life on Mars, Europa, and other extraterrestrial bodies.

Tucson researcher receives national award

Chemist F. Ann Walker received the Francis P. Garvan-John M. Olin Medal for her research on heme proteins, including nitrophorin, a molecule found in kissing bugs that releases nitric oxide to facilitate feeding. Her work provides insight into the function of heme proteins and their role in the immune system.

St. Paul researcher receives national award

Philip Portoghese, a medicinal chemist at the University of Minnesota, has received the Alfred Burger Award in Medicinal Chemistry from the American Chemical Society for his work on opioid receptors. His research reveals how drugs such as morphine interact with these receptors, enabling the creation of new, more effective drugs.

Albuquerque researcher receives national award

George Samara, a chemist from Albuquerque, NM, has been honored by the American Chemical Society for his exceptional research management skills. He was awarded the Earle B. Barnes Award for Leadership in Chemical Research Management for his contributions to advancing solar cell technology and developing unique semiconducting materials.
