About 800 participants from around the world will be in Bloomington this week for the 21st American Peptide Society Symposium, a forum for exchanging cutting-edge developments in biotechnology.
Researchers have conducted the first global analysis of the health and productivity of ocean plants, as revealed by a unique signal detected by a NASA satellite. Ocean scientists can now remotely measure the amount of fluorescent red light emitted by ocean phytoplankton and assess how efficiently the microscopic plants are turning sunlight and nutrients into food through photosynthesis.

(Boston) -- A Boston University?led research team has identified the structural underpinnings of a widely-known enzyme -- acetoacetate decarboxylase (AADase) -- that was first described correctly more than 43 years ago including how it accelerates its target reaction. Until now it has never been fully explained how the reactions occur in the environment of the cell.
RICHLAND, Wash. -- Some researchers hope to turn plants into a renewable, nonpolluting replacement for crude oil. To achieve this, scientists have to learn how to convert plant biomass into a building block for plastics and fuels cheaply and efficiently.
A new study by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of California, Santa Barbara (UCSB) is the first to quantify the amount of oil residue in seafloor sediments that result from natural petroleum seeps off Santa Barbara, California.
RICHLAND, Wash. -- By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. The results suggest that lead generated by human activities causes clouds to form at warmer temperatures and with less water.
Combating several human pathogens, including some biological warfare agents, may one day become a bit easier thanks to research reported by a University of Iowa chemist and his colleagues in the April 16 issue of the journal Nature.
A new therapy for metastatic prostate cancer has shown considerable promise in early clinical trials involving patients whose disease has become resistant to current drugs.
Both cancer cells and the chemicals used to make bombs can foil detection because they appear in trace amounts too small for conventional detection techniques. Tel Aviv University has developed the ultimate solution: a molecule that can magnify weak traces of "hidden" molecules into something we can detect and see.
Eds: A terrific comment back-and-forth has developed on this post since we published it March 24. If your interests trend toward particle physics and cold fusion, treat yourself with a read.
Researchers are reporting compelling new scientific evidence for the existence of low-energy nuclear reactions (LENR), the process once called “cold fusion” that may promise a new source of energy.
Researchers may be able to "freeze" water into a solid, not by cooling but by confining it to narrow spaces less than one-millionth of a millimeter wide, according to new results from an interdisciplinary team of scientists and engineers.
A Dutch researcher has developed a technique for making LCDs (liquid crystal displays) without the need for cleanrooms. This technique is simpler and cheaper than current methods and is based entirely upon the self-ordering of molecules on a surface. Furthermore, the chemist has shown that these LCDs can be used to make DNA visible to the naked eye.
A chemist at Washington University in St. Louis has found surprisingly tough enzymes in a bacterium that ''just says no to acid.'' Acid resistance is a valued trait for both pills and human pathogens. The bacterium Acetobacter aceti makes unusually acid-resistant enzymes in spades, which could make the organism a source for new enzyme products and new directions in protein chemistry. Chemist Joe Kappock is studying a bacterium that resists both acid and alcohol, making the bacterium simply irresistible for its potential applications.
Sending your favorite suit to the dry cleaners could one day become an infrequent practice. Researchers at Clemson University are developing a highly water-repellant coating made of silver nanoparticles that they say can be used to produce suits and other clothing items that offer superior resistance to dirt as well as water and require much less cleaning than conventional fabrics.
