AND NOW: Scientist Develops Artificial Blood … In Translyvania

– A Romanian Scientist Claims to Have Developed Artificial Blood (Smithonian, Nov 4, 2013):

Science, in all its grand ambition and contemporary sophistication, doesn’t quite have what it takes yet to replicate anything like blood. It not only delivers oxygen and essential nutrients, but also serves a host of other functions crucial for our survival, such as fighting infections, healing injuries and regulating hormones. So far, researchers have concentrated the bulk of their efforts on the more modest goal of creating something that can at least effectively carry out the vital role of transporting oxygen throughout the body.

This kind of “artificial blood” would be a useful substitute for critical circumstances such as medical emergencies, when the body can’t do this on its own. It could also be designed to be sterile, unlike real blood, which can be infected and infect others during a transfusion. And while donated blood requires refrigeration, a synthetic version could be made to last longer and be readily available for various life-or-death situations, even on the battlefield.

The latest bearer of hope for such a potential breakthrough comes from a research facility located in the Transylvanian city of Cluj-Napoca, of all places. (Yes, Translyvania is a real place in Romania.) Researcher Radu Silaghi-Dumitrescu, a professor at Babes-Bolyai University, has been working on a unique concoction and his work has progressed to the point where he and his team successfully transfused a blood substitute into mice—without them experiencing any ill effects, according to a report by the Romanian news outlet Descopera. He intends for the lab-engineered blood to work inside the body for several hours or even up to an entire day as the body replenishes itself.

People Living Downwind Of Alberta’s Oil And Tar Sands Operations Are Getting Blood Cancer

– People Who Live Downwind Of Alberta’s Oil And Tar Sands Operations Are Getting Blood Cancer (Climate Progress, Oct 28, 2013):

A new study has found that levels of air pollution downwind of the largest tar sands, oil and gas producing region in Canada rival levels found in the world’s most polluted cities. And that pollution isn’t just dirtying the air — it also could be tied increased incidence of blood cancers in men that live in the area.The study, published last week by researchers from University of California Irvine and the University of Michigan, found levels of carcinogenic air pollutants 1,3-butadiene and benzene spiked in the Fort Saskatchewan area, which is downwind of the oil and tar sands-rich “Industrial Heartland” of Alberta. Airborne levels of 1,3-butadiene were 322 times greater downwind of the Industrial Heartland — which houses more than 40 major chemical, petrochemical and oil and gas facilities — than upwind, while downwind levels of benzene were 51 times greater. Levels of some volatile organic compounds — which, depending on the compound, have been linked to liver, kidney and central nervous system damage as well as cancer — were 6,000 times higher than normal. The area saw concentrations of some chemicals that were higher than levels in Mexico City during the 1990s, when it was the most polluted city on the planet.

AND NOW: Genetically Modified Rice Created To Produce Human Blood

by

– Genetically modified rice created to produce human blood (Telegraph, Nov. 6, 2011):

Grains of rice have been genetically modified by scientists so they produce a key component of human blood in an attempt to provide an alternative to donations.

The protein, extracted from rice plants containing human genes, could be used in hospitals to treat burns victims and help patients who have suffered severe blood loss.

The scientists behind the research claim it will provide a plentiful and safe alternative to products from human blood donations, which are in short supply due to falling numbers of donors, and get around the need to screen for diseases such as HIV and hepatitis.
