(Pensoft Publishers) Scientists from the Southwest University, Chongqing, China, have found a new species and a new subspecies of cockroach. What makes these creepy crawlies distinctive from the cockroaches most of us know is that they don't infest houses, on the contrary they prefer to live a hermit life hidden away drilling logs, far away from human eyes. The study was published in the open-access journal ZooKeys.
(Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research) Ingestion of microplastic particles does not mechanically affect marine isopods. This was the result of a study by biologists at the North Sea Office of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research that was published recently in the journal Environmental Science and Technology. The study marks the launch of a series of investigations aimed at forming a risk matrix on the sensitivity of different marine species to microplastic pollution.
(Helmholtz Centre for Ocean Research Kiel (GEOMAR)) To continue its striking development, ocean acidification research needs to bridge between its diverging branches towards an integrated assessment. This is the conclusion drawn by Professor Ulf Riebesell from the Helmholtz Centre for Ocean Research Kiel and Dr. Jean-Pierre Gattuso from the French Centre National de la Recherche Scientifique and Universite Pierre et Marie Curie. In a commentary in the journal Nature Climate Change, the two internationally renowned experts reflect on the lessons learned from ocean acidification research and highlight future challenges.
(National University of Singapore) Researchers at the Mechanobiology Institute, National University of Singapore have identified a novel mechanosensitive regulation of epithelial tube contraction. These findings are published on Dec. 19, 2014, in Current Biology.
(Oxford University Press) Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains.

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.
