Engineering breakthrough will allow cancer researchers to create live tumors with a 3D printer
(Phys.org) —Drexel's Wei Sun, PhD, Albert Soffa chair professor in the College of Engineering, has devised a method for 3D printing tumors that could soon be taking cancer research out of the petri dish.
A civil war inside our cells: Scientists show how our bodies fight off 'jumping genes'
There's a civil war going on inside every one of the 37 trillion cells in your body. Now, University of Michigan scientists have uncovered how your cells keep this war from causing too much collateral damage.
Genetic code of the deadly tsetse fly unraveled
Mining the genome of the disease-transmitting tsetse fly, researchers have revealed the genetic adaptions that allow it to have such unique biology and transmit disease to both humans and animals.
Ocean microbes display remarkable genetic diversity

From liability to viability: Genes on the Y chromosome prove essential for male survival
Despite a well-documented history of dramatic genetic decay, the human Y chromosome has over the course of millions of years of evolution managed to preserve a small set of genes that has ensured not only ...
Researchers find fish 'yells' to be heard over human made noise
Field study shows how sailfish use their bill to catch fish
Rainbow trout genome sequenced

Brain size matters when it comes to animal self-control
(Phys.org) —Chimpanzees may throw tantrums like toddlers, but their total brain size suggests they have more self-control than, say, a gerbil or fox squirrel, according to a new study of 36 species of mammals ...
A plague in your family: The independent evolution of harmful organisms from one bacterial family
For the first time, researchers have studied the Black Death bacterium's entire family tree to fully understand how some of the family members evolve to become harmful.
More questions than answers as mystery of domestication deepens
(Phys.org) —We all think we have a rough idea of what happened 12,000 years ago when people at several different spots around the globe brought plants under cultivation and domesticated animals for transport, ...
Bulletproof nuclei? Stem cells exhibit unusual absorption property
Stem cells – the body's master cells – demonstrate a bizarre property never before seen at a cellular level, according to a study published today from scientists at the University of Cambridge. The property ...
