New insights into mosquitoes' role as involuntary bioterrorists

For many years scientists thought that mosquitoes provided the disease organisms which they spread with a relatively free ride because the insects didn't have much in the way of natural defenses to fight off these microscopic ...

New insights into placebo effect

(Phys.org)—Mathematical models developed by scientists at the University of Bristol are providing new insights into why the placebo effect exists and when it should occur. Their research is published today in the journal ...

Study maps vaccine for deadly pathogenic fungus

University of Alberta researchers have made breakthrough use of 3-D magnetic resonance technology to map the structure of a common fungus that is potentially deadly for individuals with impaired immune function. The work ...

Cells on the move

Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments. Cells without functional lamellipodia are still highly motile ...

Immunoproteasome crystal structure determined

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells ...

Sexual healing? Not likely

(PhysOrg.com) -- A new study shows the production of sperm is more biologically taxing than previously thought, and expending energy on it has significant health implications.

New information on the waste-disposal units of living cells

Important new information on one of the most critical protein machines in living cells has been reported by a team of researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and ...
