With many of the world’s 18 species of penguins experiencing substantial declines during the past two decades, international scientists writing in the current issue of Conservation Biology are calling for marine protected areas and partially protected areas to help penguins cope with food scarcity, oil pollution, climate change and being caught in fishing nets.

Washington, DC — A study published in the July 17, issue of the journal PLOS ONE found that more than 80% of tropical forests in Malaysian Borneo have been heavily impacted by logging. (more…)
ANN ARBOR — The idea of corporate social responsibility to manage common-pool resources such as water, forests and pastures is flawed, says a University of Michigan researcher.
Aneel Karnani, associate professor of strategy at the U-M Stephen M. Ross School of Business, says that when a common-pool resource is left without any enforced property rights, it results in degradation and destruction of the resource. (more…)
PASADENA, Calif. – An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study. These results, together with observed recurrences of droughts every few years and associated damage to the forests in southern and western Amazonia in the past decade, suggest these rainforests may be showing the first signs of potential large-scale degradation due to climate change.
An international research team led by Sassan Saatchi of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., analyzed more than a decade of satellite microwave radar data collected between 2000 and 2009 over Amazonia. The observations included measurements of rainfall from NASA’s Tropical Rainfall Measuring Mission and measurements of the moisture content and structure of the forest canopy (top layer) from the Seawinds scatterometer on NASA’s QuikScat spacecraft.

Researchers at Michigan State University have discovered a protein that does its best work with one foot in the grave.
The study, which appears in the current issue of the Journal of Biological Chemistry, focuses on the nontraditional lifestyle of Retinoblastoma tumor suppressor proteins, which could lead to new ways to treat cancer.
“Retinoblastoma proteins are unique in that they use controlled destruction to do their jobs in a timely but restrained fashion,” said Liang Zhang, a lead author and MSU cell and molecular biology graduate student. “This is an unusual way for proteins to act.” (more…)
For treatment of vocal fold disorders, UD researchers look to insect protein
A one-inch long grasshopper can leap a distance of about 20 inches. Cicadas can produce sound at about the same frequency as radio waves. Fleas measuring only millimeters can jump an astonishing 100 times their height in microseconds. How do they do it? They make use of a naturally occurring protein called resilin.
Resilin is a protein in the composite structures found in the leg and wing joints, and sound producing organs of insects. Highly elastic, it responds to exceptionally high rates of speed and demonstrates unmatched resilience after being stretched or deformed. (more…)
*In a newly published study, researchers found the majority of medical residents surveyed experienced a decline in empathy over the course of the oft-used “long-call” shift.*
Fatigue and sleep deprivation are undisputed job descriptors for medical residents, but results from a new study indicate the common “long-call” shift may have adverse effects not only for residents, but also their patients.
University of Arizona alumna Stacey Passalacqua, now a visiting assistant professor at James Madison University’s School of Communication, surveyed nearly 100 medical residents at several different hospitals. (more…)
*Berkeley Researchers Provide Detailed Look at Proteasome’s Regulatory Particle*
Important new information on one of the most critical protein machines in living cells has been reported by a team of researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. The researchers have provided the most detailed look ever at the “regulatory particle” used by the protein machines known as proteasomes to identify and degrade proteins that have been marked for destruction. The activities controlled by this regulatory particle are critical to the quality control of cellular proteins, as well as a broad range of vital biochemical processes, including transcription, DNA repair and the immune defense system.
