Vampire bats keep out of trouble by running

... they power their gait. "Unlike most animals which use their hind legs as a source of power, these exceptional creatures power their run with their forelimbs," Hermanson explains. Getting most of the push from their long forelimbs -- actually their wings and therefore very strong -- the bats run more lik...

Use of PET can reduce, may eliminate more strenuous drug development trials with animals

A number of articles explore the use of positron emission tomography (PET) and small animal imaging--nonsurgical techniques that open the door to understanding and treating human diseases--in the April issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine. A major bene...

Hirsute Or Hairless? Two Proteins May Spell The Difference

... buds. In a new study, Elaine Fuchs and colleagues use a three-pronged approach—involving gene expression analysis, transgenic mice, and cell cultures—to study how epithelial buds, the precursors of hair follicles, form. Their experiments point to two key actors in a signaling pathway that molds a target...

...ersity. Though other scientists have attempted to use PET to noninvasively monitor maternal-fetal drug exchange and pharmacokinetics (how quickly a drug is taken up and distributed among the body's organs), the PET technique alone did not provide adequate anatomical detail of the tiny fetal organs.
