A family of cancer-fighting molecules helps blood stem cells in mice decide when and how to divide, say researchers at the Stanford University School of Medicine. Blocking the molecules' function spurs the normally resting cells to begin proliferating strangely -- making too much of one kind of cell and not enough of another. Many types of human blood cancers involve a similar disruption in the expression of that same family of molecules. The blood stem cells' misguided enthusiasm also...

Lorry I. Lokey, the Business Wire founder and philanthropist, is giving $75 million to the Stanford University School of Medicine to help build what is expected to be the nation's largest center for stem cell research, the medical school announced Oct. 6. Lokey's gift will help give rise to a 200,000-square-foot facility that will be known as the Lorry I. Lokey Stem Cell Research Building. The modern, four-story building along Campus Drive will house 350 scientists working together to...

STANFORD, Calif. - "You can eat your relatives but not your friends," could be the off-kilter credo of a tiny marine invertebrate called a sea squirt that can physically merge with, and parasitize, its own kin. The trigger for this unseemly behavior has now been traced to a single gene, isolated by researchers at the Stanford University School of Medicine. That gene also points to a common origin with the vertebrate immune system, far back in animal evolution, potentially shedding light on...

STANFORD, Calif. - Older people are more prone to infections and have a higher risk of developing leukemia, and now researchers at Stanford University School of Medicine have one hint as to why that may be. The group found that in mice, the bone marrow stem cells responsible for churning out new blood cells slow down in their ability to produce immune cells, leaving older mice with fewer defenses against infection. These new findings, published in the June 20 online issue of Proceedings of...

mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
