New Ways to Disarm Deadly South American Hemorrhagic Fever Viruses
March 07, 2010
New World hemorrhagic fevers are emerging infectious diseases found in South America that can cause terrible, Ebola-like symptoms. Now HHMI researchers have discovered exactly how one virus latches onto and infects human cells, offering a much-needed lead toward new treatments.

Asexual Plant Reproduction May Seed New Approach for Agriculture
March 07, 2010
An HHMI international research scholar and his colleagues have moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture. More

Blood Vessel Cells Promote Self-Renewal of Blood Stem Cells
March 05, 2010
Endothelial cells, the building blocks of the vascular system, keep blood stem cells dividing healthily in a lab dish much longer and more effectively than previous methods of growing the cells. More

New Tool Illuminates Connections between Stem Cells and Cancer
February 20, 2010
A new tool to understand how cancers grow presents a new opportunity to identify novel cancer drugs. Owen Witte's team has been able to break apart human prostate tissue, extract the stem cells in that tissue, and alter those cells genetically so that they spur cancer. More

Stem Cells: Turning Back the Molecular Clock to Reverse Rapid Aging
February 17, 2010
Researchers have created a group of stem cells from patients who have a disorder that causes accelerated aging and bone marrow failure. Using a genetic reprogramming technique to “turn back the molecular clock” in these cells appears to reset the cells and reverses rapid aging. More

New Vaccine Shows Promise Against Malaria in Early-Stage Study
February 04, 2010
A new vaccine tested in 100 West African children triggers the immune system to produce antibodies against the malaria parasite at levels normally seen only in adults who have strong resistance to the disease. More
