An international research team warns of mineral supply constraints as green technology demand increases. The team, led by the University of Delaware's Saleem Ali, says mining exploration isn’t keeping up with future demand and better global resource governance is needed to address the challenge.

Wet ‘Dry Season’ Damaged Valuable Ornamental Plants

Purplevelvet080515.jpg

Florida’s winters are usually dry, but the wet winter of 2015-2016 helped spread pathogens that destroyed ornamental plants in Miami-Dade County. That’s a problem in an area where the industry generated an estimated $998 million annually in sales in 2015, University of Florida Institute of Food and Agricultural Sciences researchers say.

Researchers Create Self-Sustaining Bacteria-Fueled Power Cell

Instead of oil, coal, or even solar energy, self-sustaining bacterial fuel cells may power the future. Researchers at Binghamton University, State University of New York have developed the next step in microbial fuel cells (MFCs) with the first micro-scale self-sustaining cell, which generated power for 13 straight days through symbiotic interactions of two types of bacteria.

Cornell Evolutionary Biologist Explains How to 'Walk the Tree of Life'

Harry Greene, professor of ecology and evolutionary biology at Cornell University, and Cissy Ballen of the University of Minnesota have just published a paper in PLOS Biology, “Walking and Talking the Tree of Life: Why and How to Teach About Biodiversity,” discussing why the evolutionary TOL approach to biodiversity is best, to what extent the traditional taxonomy is still used and how to teach TOL using an active learning approach.

New Cell Membrane Fusion Model Challenges Dogma

MembraneFusioninYeastandHumans.jpg

Membrane fusion lies at the heart of many cell functions—from the secretion of antibodies to the release of neurotransmitters. For more than two decades, one view of the process by which membrane fusion occurs has been accepted as dogma; now recent studies indicate that fusion is more complex. These discoveries are being regarded by at least one leading cell biologist as “textbook changing” and could alter how we develop drugs that affect membrane fusion activities.

How Do Metals Interact with DNA?

Since a couple of decades, metal-containing drugs have been successfully used to fight against certain types of cancer. The lack of knowledge about the underlying molecular mechanisms slows down the search for new and more efficient chemotherapeutic agents. An international team of scientists, led by Leticia González from the University of Vienna and Jacinto Sá from the Uppsala University, have developed a protocol that is able to detect how metal-based drugs interact with DNA.

University of Utah bioengineering researchers have discovered that damage to collagen, the main building block of all human tissue, can occur much earlier at a molecular level from too much physical stress. This could be helpful for some who want to know earlier if they are developing diseases such as arthritis or for athletes whose bodies are taking a toll.
