SCIENCE: The Connection Between Species Extinction, Organized Crime, and the Spread ofDisease By Cristian SamperThe below statement was issued in observance of Wildlife Conservation Day. To learn about the Wildlife Conserva-tion Society, visit www.wcs.org.Illegal wildlife trafficking may prove to be the demise of many of our Earths species. Further, this activity -- whichis snuffing out the last populations of elephants, tigers and other animals -- finances organized crime and aug-ments the spread of zoonotic diseases. There is no lack of reasons to join efforts to stop wildlife trafficking. To-gether, we need to protect the source, break the chain and stop demand.At a recent event in Washington, D.C., U.S. Secretary of State Hillary Clinton reiterated words spoken by the State Photo by T.

She had relapsed twice afterchemotherapy, and doctors had run out of options.Desperate to save her, her parents sought an experimental treatment at the Children’s Hospital ofPhiladelphia, one that had never before been tried in a child, or in anyone with the type of leukemiaEmma had. The experiment, in April, used a disabled form of the virus that causes AIDS to reprogramEmma’s immune system genetically to kill cancer cells.The treatment very nearly killed her. But she emerged from it cancer-free, and about seven monthslater is still in complete remission. She is the first child and one of the first humans ever in whom newtechniques have achieved a long-sought goal — giving a patient’s own immune system the lastingability to fight cancer.

The study was recently published in the journal Nature Geoscience. A reduction of the ice sheets in Antarctica and Greenland will affect the water levels of the worlds oceans. It is therefore problematic that we currently have insufficient knowledge about the ocean circulation near large glaciers in West Antarctica. This means that researchers cannot predict how water levels will change in the future with any large degree of certainty.Photo by John Lester (flickr user). Under Creative Commons License. "There is a clear reduction in the ice mass in West Antarctica, especially around theglaciers leading into the Amundsen Sea," says researcher Lars Arneborg from the Department of Earth Sciences at the University ofGothenburg. One reason why West Antarctica is particularly sensitive is that the majority of the ice rests on areas that are belowsea level. Warm sea water penetrates beneath the ice, causing increased melting from underneath.Read full article at: http://phys.org/news/2012-12-sea-antarctic-glaciers.html

Cancer cells circulating in the bloodstream can form metasta-ses—new tumors. Detecting these rare circulating cancer cells in a blood sample is much less invasive than a standard tumor bi-opsy, and could prove useful for monitoring cancer progression and detecting recurrence. While studying what happens to cancer cells when they are subjected to powerful fluid forces, like those encountered in the bloodstream, researchers at the University of Iowa unexpectedly discov- ered that cancer cells are actually more likely to survive this turbulent fluid environment than nor- mal epithelial cells. The researchers suggest this surprising "hardiness" could be a potential bio- marker for detecting and studying cancer cells in the blood. The findings were published Dec. 3 in the journal PLOS ONE. "For many years, its been assumed that these circulating cancer cells are quite fragile, and they es- sentially get ‘blended’ by the fluid forces in the blood," says Michael Henry, associate professor of molecular physiology and biophysics at the UI Carver College of Medicine and lead study author. "But there was no real direct evidence for how fluid forces in the blood affect cancer cells. "What we found was that normal cells were, as expected, quite sensitive to the fluid forces and most did not survive. But, surprisingly, the cancer cells seemed to be remarkably resistant."Invadopodium extension by a cancer cellA cancer cell (red) extends alonginvadopodium through a matrigel Henry suggests that resistance to fluid shear stress might be a way to distinguish benign from malig-ba s e me nt me mb ra ne ( g re e n) . nant cells in circulating tumor cell samples.

Using a simple syringe and precise mathematical calculations of fluid dynamics, the UI team created an experimental system to mimic the short bursts of turbulent flow that a can-cer cell might experience in the blood. Passing a suspension of cells through the syringe needle allowed the researchers to studythe effect of a series of millisecond pulses of high fluid shear stress on a variety of different cancer cell types (prostate, breast, andmelanoma) as well as normal epithelial cells from breast and prostate tissue.After 10 passages though the syringe needle at high flow rate, around half of the cancer cells were still alive. In contrast, very fewnormal epithelial cells survived the process.Closer examination of the cell survival data revealed an additional twist. The rate at which the cancer cells are destroyed by pas-sage through the syringe is not constant over all 10 passages. Instead, exposure to fluid shear stress during the earlier passagesseems to trigger adaptive responses in cancer cells that actually increase the cells resistance to fluid shear stress.The UI team went on to show that this "toughening up" process appears to involve expression of common cancer-causing genes.They also showed that blocking the signaling pathway controlled by one of these oncogenes reduced the cancer cells resistance tofluid shear stress.Reat more about this topic at: http://now.uiowa.edu/2012/12/unexpected-toughness-may-mark-out-cancer-cells-blood

Also, the presence of the Peruvian wigeon (Anas sibilatrix) was confirmed. This species has notbeen seen since 1850. These findings were announced by Dennis Osorio, coordinator of this contestthat gathered some of the world’s most recognized ornithologists, who were part of a total of sixteams from five countries: United States, United Kingdom, South Africa, Spain, and Brazil.In six days, participants had to identify the largest number of birds, in a trip that started at the Ama- The swift was seen in Tambopata byzon Tambopata Natural Reserve, and ended at the Machu Picchu rainforest.

Dennis Osorio commented that this is the first time in South America that a competition like this has taken place over several days, as these contests last usually 24 hours. Following Colombia, Peru is the second country in the world in diversity of birds, counting on more than 1800 species in its different ecosystems.

In North America, for example, sparrows even use the cellulose from the cigarette butts. However, it was unknown untilnow, why these birds used them. Recently, scientists discovered that, in addition to be useful as thermal isolators, cigarette buttsprevented the nests of being invaded by parasites and other anthropods, thanks to the smell of nicotine they retain.Read more at: http://elcomercio.pe/actualidad/1506226/noticia-aves-usan-colillas-cigarros-alejar-parasitos-nidos
