U of U biologists Phyllis Coley and Tom Kursar spent five years working in Panama to conserve rainforests and promote economic development by stimulating a native industry aimed at finding new medicines in rainforest plants.

Plants develop chemical defenses to survive attackes by insects such as these grasshoppers. Those chemicals sometimes can be developed into medicines to combat human diseases.

Exploit Plant Defenses, Build Local Drug Discovery Industry
Misty-eyed idealism alone will not save Earth’s dwindling tropical rainforests. But a five-year, $3 million study in Panama indicates rainforests can be protected if the pharmaceutical industry establishes Third World laboratories and hires local researchers to look for new medicines extracted from plants that evolved defenses against insects.
“Until now, efforts to find drugs in the rainforest haven’t really led to rainforest conservation,” says Tom Kursar, an associate professor of biology at the University of Utah, who led the study with his wife, biology Professor Phyllis Coley. “But we have developed a novel approach that provides a direct link between looking for drugs and promoting conservation and economic development in biodiversity-rich countries.”

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
