(Burness Communications) A new study released today presents powerful evidence that clearing trees not only spews carbon into the atmosphere, but also triggers major shifts in rainfall and increased temperatures worldwide that are just as potent as those caused by current carbon pollution. Further, the study finds that future agricultural productivity across the globe is at risk from deforestation-induced warming and altered rainfall patterns.
(Harvard School of Public Health) Women exposed to high levels of fine particulate matter specifically during pregnancy -- particularly during the third trimester -- may face up to twice the risk of having a child with autism than mothers living in areas with low particulate matter, according to a study from Harvard School of Public Health. The greater the exposure, the greater the risk, researchers found. It was the first US-wide study exploring the link between airborne particulate matter and autism.
(Society for Research in Child Development) A study of children born prematurely has found differences in a subtle but important aspect of memory: the ability to form and retrieve memories about context. The study examined 33 German 8-to 10-year olds using magnetic resonance imaging to measure the volume of the hippocampi. The results suggest that the maturational state of the hippocampus at the time of birth influences the maturation of certain memory functions even at 8- to 10-years old.
(Thomas Jefferson University) The cause of prostate cancer may be linked to Parkinson's disease through a common enzyme.

Today we are reposting a blog from the Biodiversity Heritage Library. Thank you to Grace Costantino for sharing.
This month, we’re publishing a series of blog posts outlining the importance of biodiversity literature, made available for free and open access through the Biodiversity Heritage Library, to today’s scientific research and conservation initiatives. With your help, we can help save biodiversity.
The Biodiversity Heritage Library (BHL) is revolutionizing the way scientific research is conducted by providing free and open access to biodiversity literature and archives representing over 500 years of scientific exploration, research, and discovery.
What’s so special about Historic Literature and Archives?
Historic literature and archival fieldbooks provide information that is critical to studying biodiversity. These documents are replete with data detailing the morphology, phylogeny and ethology of earth’s species. In many cases, this literature constitutes the only available knowledge for rare, endangered, and extinct species.
In addition to species data, published books and fieldbooks capture ecosystem profiles, distribution maps, inter-dependency observations, and geological and climatic records. They also provide an historical perspective on species abundance,habitat alteration, and human exploration, culture and discovery.
This information has a multitude of applications in modern-day science. It is used to populate species databases and datasets that inform present-day research. It not only allows scientists to study biodiversity, but also to save it by enabling new species identification and facilitating the development of holistic conservation methods that integrate all of the factors necessary for a species’ wellbeing into its overall protection strategy. Furthermore, the discoveries captured in historic literature provide the foundations upon which contemporary models, theories anddisciplines are based.
Sadly, much of these publications and archival content are available in only a few select libraries in the developed world.
“Science is all about disseminating knowledge and building upon what has come before, yet so much of our knowledge of plants and animals has remained inaccessible to those who could make use of it,” laments Dr. John Sullivan, an evolutionary biologist with the Academy of Natural Sciences, Philadelphia and Cornell University. “This has been a big part of the ‘taxonomic impediment.’”
The Biodiversity Heritage Library is Alleviating the Taxonomic Impediment
The Biodiversity Heritage Library boasts a collection of over 45 million pages from over 150,000 volumes and has served more than 3.5 million people in nearly every country since its launch in 2007. Additionally, BHL has made over 93,000 of the illustrations within its collection available in Flickr, which in turn have been viewed over 80 million times. Services such as taxonomic name finding tools, custom PDF downloads, and open APIs allow users to easily locate and reuse these resources.
“BHL is radically changing the status quo and democratizing access to knowledge about biodiversity,” lauds Dr. Sullivan. “Now anybody in the world has instant access to the original species description in a couple of clicks!”

This is an image of a breast tumor identified as Epi-Luminal B of poor prognosis. Breast cancer is the most common in women. One in nine will suffer breast cancer over their lifetime. Progress in prevention and early detection, and the use of chemotherapy after surgery (adjuvant chemotherapy), have achieved significantly increase survival in this disease in the last ten years, but much remains to be done.
