Hirsute Or Hairless? Two Proteins May Spell The Difference

...pmental stages, this study lays the foundation for dissecting the mechanisms that connect two key processes—intercellular remodeling and proliferation—in epithelial development. And since the consequences of TGF-β2 activity seen here in the hair bud more closely resemble certain types of skin cancer progression...

miRNA profiling

... analysis provides an important starting point for dissecting of function and evolution of small RNAs and their targets. ...

Scientists journey to southern Africa to unravel the secret world of elephant communication

... Stanford, and undergraduate Christina Alarcon are dissecting the foot of an Asian elephant that recently died at a zoo. Preliminary results reveal a high density of Pacinian corpuscles in the front of the foot and along the edges--a finding consistent with the notion that elephants are sensing seismic signals ...

Novel plague virulence factor identified

...reated. "Dr Aballay has developed a new model for dissecting the ways pathogens such as the plague can infect and kill their hosts," said Pamela Marino, Ph.D., scientist at the National Institute of General Medical Science. "This creative approach should improve our ability to develop new medicines to treat su...

MIT engineers probe spiders' polymer art

... with furry knuckles." But he quickly settled into dissecting the peanut-sized and -shaped protuberance on the spiders' backs containing their silk-producing glands and spinnerets. Spiders don't actually spin ("spinning" refers to the age-old art of drawing out and twisting fibers to form thread); instead, th...

Worms produce surprise insight into human fever

...nt microbial colonization of the intestine. In dissecting two conserved pathways required for C. elegans immunity to bacteria, Aballay found a wealth of data on innate immunity plus a surprising insight into another classic metazoan response to infection fever. The first pathway was p38 MAPK/CED-3, wh...

Computer scientists unravel 'language of surgery'

...perform surgery, including tasks such as suturing, dissecting and joining tissue. The team's long-term goal is to develop an objective way of evaluating a surgeon's work and to help doctors improve their operating room skills. Ultimately, the research also could enable robotic surgical tools to perform with g...

Motor protein plays key role in connecting neurons

... they will form a synapse," says Dr. Xiong, who is dissecting how neurons first connect with the goal of helping restore communication lost in spinal cord injuries and other disorders. "Growth is precisely controlled during development," she says and errant growth can impair brain wiring or connectivity...
