Science races against tick-borne virus

Two groundbreaking discoveries by USC researchers could lead to medications and a vaccine to treat or prevent a hemorrhagic fever transmitted by a new tick species before it spreads across the United States.

For gait transitions, stability often trumps energy savings

A dog's gait, according to the American Kennel Club, is "the pattern of footsteps at various rates of speed, each distinguished by a particular rhythm and footfall." When dogs trot, for example, the right front leg and the ...

Songbird data yields new theory for learning sensorimotor skills

Songbirds learn to sing in a way similar to how humans learn to speak—by listening to their fathers and trying to duplicate the sounds. The bird's brain sends commands to the vocal muscles to sing what it hears, and then ...

Science learns from its mistakes too

Scientific studies should always be published irrespective of their result. That is one of the conclusions of a research project conducted by the German Centre for the Protection of Laboratory Animals at the German Federal ...

Why some animals still have a penis bone

A team of researchers affiliated with several institutions in the U.K. has found a possible explanation for why some animals still have a penis bone—"prolonged intromission." In their paper published in Proceedings of the ...

Reconstructing skin on a chip

Microfluidics could fulfill a growing need for alternatives to animal testing for the development of pharmaceuticals and cosmetics. A multidisciplinary team, led by Zhiping Wang from the A*STAR Singapore Institute of Manufacturing ...

Tumorcode, a software to simulate vascularized tumors

The tumor vasculature is a major target of anticancer therapies. Rieger, Fredrich and Welter at Saarland University, Germany have been pursuing a quantitative analysis of the physical determinants of vascularized tumors for ...

Engineers test drug transfer using placenta-on-a-chip

Researchers at the University of Pennsylvania's School of Engineering and Applied Science have demonstrated the feasibility of their "organ-on-a-chip" platform in studying how drugs are transported across the human placental ...
