Barkcloths demonstrate women's importance
Dutch researcher Anna-Karina Hermkens has produced a description and analysis of the dynamics of gender and identity in the culture of the Maisin, an indigenous group from Papua New Guinea. She made this analysis by following the production and use of an object made by the women, painted barkcloth. (2005-07-07)

100-year-old specimens at California museum help determine when avian pox hit Galapagos
A research team from across the United States and Ecuador has pinpointed 1898 as the year the avipoxvirus, or avian pox, hit the Galapagos Islands and started infecting its birds. This estimation is vital to understanding avian diseases that affect today's Galapagos birds. The scientists' paper on the subject, (2011-01-13)

Triage for plants: NYBG scientists develop and test rapid species conservation assessment technique
Faced with a host of environmental threats, many of the world's plant species are believed to be at risk of extinction. But which species? To answer that question, scientists at The New York Botanical Garden developed a streamlined method for assessing the conservation status of large numbers of species. Evaluating the flora of Puerto Rico, they found that 459 species -- 23 percent of the flora -- should be classified as (2012-08-16)

Study clarifies kinship of important plant group
Asterids comprise around 100,000 flowering plants, from heather to tomatoes. Up to now, their family relationships had not yet been fully clarified. A new study by the University of Bonn, Pennsylvania State University (USA) and Fudan University (China) has now somewhat closed this knowledge gap. It is the world's most detailed phylogenetic analysis ever conducted for asterids. The results of the study have been published in the journal Molecular Biology and Evolution. (2020-08-05)

Collection provides tools to improve clinical research in Africa and Asia
Quality assurance of clinical research is critical to ensure meaningful results in compliance with universal ethical standards. Good Clinical Practice and Good Clinical Laboratory Practice codes have been developed as tools to ensure data integrity and ethical study conduct. However, these codes are often considered beyond reach for resource constrained settings. A recently published collection in PLOS Neglected Tropical Diseases shares experiences, lessons learned and practical tools developed during clinical research on neglected tropical diseases in Africa and Asia.

Paleontologists discover largest dinosaur foot to date
As it turns out, 'Bigfoot' was a dinosaur -- a giant, plant-eating one. A new study based on fossils excavated in Wyoming reveals the largest dinosaur foot ever found and identifies it as a brachiosaur, a type of sauropod dinosaur that was among the largest land animals on Earth. The work, published today in the journal PeerJ, also confirms that 150 million years ago brachiosaurs called a huge swath of North America home. (2018-07-24)

Toward more effective paleolgenetic analysis
A team led by Eva-Maria Geigl of CNRS (France)has just shown that DNA preserved in bones undergoing fossilization deteriorates up to 50 times faster when stored in a museum than when the bones are buried in the ground. This study was published in the Proceedings of the National Academy of Sciences January 8 2007. (2007-01-17)

Common US snake actually 3 different species
New research reveals that a snake found across a huge swath of the Eastern United States is actually three different species. Published in Molecular Phylogenetics and Evolution, analyses of the yellow-bellied kingsnake (Lampropeltis calligaster) also indicate that diversification of the snake -- and possibly of many other vertebrates living on both sides of the Mississippi River -- is influenced not by the river itself, as predominately thought, but by the different ecological environments on each side.

CHOP's Harvest toolkit offers innovative data discovery resource for biomedical researchers
A team of informatics experts and biomedical researchers introduced a new software toolkit to help researchers explore complex data sets without having to become database technicians themselves. Harvest is an open-source, highly interactive framework designed by CHOP's Center for Biomedical Informatics. (2013-10-17)

Native fish species at risk following water removal from the Colorado River
Agriculture and domestic activities consume much of the Colorado River water that once flowed to the Colorado Delta and Northern Gulf of California. The nature and extent of impact of this fresh-water loss on the ecology and fisheries of the Colorado Delta and Gulf of California is controversial. A recent publication in the journal PeerJ reveals a previously unseen risk to the unique local biodiversity of the tidal portion of the Delta. (2017-12-12)

Coelacanth reveals new insights into skull evolution
An international team of researchers presents the first observations of the development of the skull and brain in the living coelacanth Latimeria chalumnae. Their study, published in Nature, provides new insights into the biology of this iconic animal and the evolution of the vertebrate skull. (2019-04-17)

Fox invasion threatens wave of extinction, UC research finds
The effort to stop the irreversible spread of foxes in Tasmania is at a critical stage with many native species at risk of extinction, new research by University of Canberra ecologists and their collaborators published in the British Ecological Society's Journal of Applied Ecology shows. (2012-12-04)

Biologist David Lohman leads $2.5 million NSF-funded study on butterfly evolution
Dr. David J. Lohman, assistant professor of biology at The City College of New York, and his colleagues received $2.5 million in grants from the National Science Foundation for a collaborative study to resolve the evolutionary history of all butterfly species. (2015-09-21)

Jurassic crocodile discovery sheds light on reptiles' family tree
A 150 million-year-old fossil has been identified as a previously unseen species of ancient crocodile that developed a tail fin and paddle-like limbs for life in the sea. (2019-04-04)

Two centuries of Monarch butterflies show evolution of wing length
North America's beloved Monarch butterflies are known for their annual, multi-generation migrations in which individual insects can fly for thousands of miles. But Monarchs have also settled in some locations where their favorite food plants grow year round, so they no longer need to migrate. A new study of specimens collected over the last two centuries shows how wing length evolves in response to migration habits. (2020-11-02)

One-of-a-kind meteorite unveiled
The depths of space are much closer to home following the University of Alberta's acquisition of a meteorite that is the only one of its kind known to exist on Earth! (2006-04-21)

Scientists find new conclusions for how sauropod claws were used
Paleontologists at the Cleveland Museum of Natural History studied footprints of sauropod dinosaurs and found that the function of their claws were used for digging, challenging the long-held notion that sauropod claw function was to aid in gripping substrates. (2016-11-30)

UCSF scientists illuminate how microRNAs drive tumor progression
UCSF researchers have identified collections of tiny molecules known as microRNAs that affect distinct processes critical for the progression of cancer. The findings, they say, expand researchers' understanding of the important regulatory function of microRNAs in tumor biology and point to new directions for future study and potential treatments. (2009-09-16)

Microcirculation imaging
Microcirculation Imaging is the first handbook of its kind, introducing many different technical approaches for the visualization of microcirculation. Clearly structured throughout, this book is a must for every clinician and researcher relying on microcirculation imaging. (2012-06-25)

How to make fish shine
Scientists from the University of Bath have helped to figure out why shoals of fish flash silver as they twist through the water by studying how the shiny silver cells are created in zebrafish. (2018-10-10)
