Here is another great Tree of Life tattoo! This one is courtesy of Monica Quast , who is a Ph.D. student at the University of Campinas, Brazil, working on bivalve phylogeography. The organisms depicted on this version are (going clockwise): a cyanobacterium, a foraminiferan, 3 diatoms, an oak leaf and acorn, a Spirogyra cell, a red cage fungus, a stauromedusa, a nautilus, a tardigrade, an ophiuroid, and a badger.

Boy discovers microbe that eats plastic | MNN - Mother Nature Network
It's not your average science fair when the 16-year-old winner manages to solve a global waste crisis. But such was the case at last May's Canada-Wide Science Fair in Ottawa, Ontario, where Daniel Burd, a high school student at Waterloo Collegiate Institute, presented his research on microorganisms that can rapidly biodegrade plastic. Daniel had a thought it seems even the most esteemed PhDs hadn't considered. Plastic, one of the most indestructible of manufactured materials, does in fact eventually decompose.
The good news first: Emma Ware successfully defended her PhD thesis on Friday. Congratulations! Emma had studied the dynamics of pigeon courtship behaviour as a means to understand the role of the partner's responsiveness to ones own behaviour. She used a sophisticated tele-conferencing setup to manipulate the degree of “responsiveness” between two courting pigeons: The male and the female bird were located in two different rooms, but could see each other through a video interface.

Jamie Chung for TIME Growing new body parts has always been more science fiction than science reality, but that balance may quickly be shifting, at least in the lab. Relying on more sophisticated biosimulators that can better mimic body conditions, researchers have re-created the delicate architecture of a rat lung accurately enough for it to assume 95% of a normal lung's inhaling and exhaling functions. The key to their respiratory success was starting with a skeletal rat-lung template, including a matrix of blood vessels and collagen and other connective tissue, then seeding it with stem cells and nutrients to generate lifelike tissue that exchanged oxygen and carbon dioxide just like normal lung tissue. The ultimate goal is to replicate the feat on a larger scale: to replace enough human lung tissue to aid patients with emphysema or lung cancer.

VIPER
The VIPER Institute was established under the Arizona Board of Regents in 2007, based in the UA College of Medicine in formal affiliation with the College of Pharmacy’s Arizona Poison and Drug Information Center. VIPER’s mission is applied phylogenetics of venom: using clues from the genealogy of venomous animals toward discovery of new diagnostic and pharmaceutical tools and economically sustainable improvement in medical care of venom injury worldwide. The VIPER Institute strives to be a world leader in the combination of phylogenetic and drug-development resources across international boundaries, resulting in better, more cost-effective medical care for all.
DNA is extracted from human cells for a variety of reasons. With a pure sample of DNA you can test a newborn for a genetic disease, analyze forensic evidence, or study a gene involved in cancer. Try this virtual laboratory to perform a cheek swab and extract DNA from human cells. PCR is a relatively simple and inexpensive tool that you can use to focus in on a segment of DNA and copy it billions of times over. PCR is used every day to diagnose diseases, identify bacteria and viruses, match criminals to crime scenes, and in many other ways. Step up to the virtual lab bench and see how it works!
