The idea that a failure of proper cell division produces genomic instability and promotes the development of cancer was first proposed by German biologist Theodor Boveri in 1915. The fact that tumor cells often have abnormal numbers of chromosomes supports this theory, and two papers provide new, more direct evidence to support this.

New research shows that children between 8 and 15 years old who are in the upper half of the normal weight range are more likely than their leaner peers to become obese or overweight as young adults.
Structural biologists have shown how a key part of the human immunodeficiency virus changes shape, triggering other changes that allow the AIDS virus to enter and infect cells. Their findings offer clues that will help guide vaccine and treatment approaches.
Organ development in the embryo requires precise coordination and timing of cell growth in three-dimensional space to produce the correct anatomic form and shape. Researchers have demonstrated that the process of budding and branching in the developing lung is driven by mechanical forces generated within individual cells.
HMS researchers report that older physicians may be less likely to deliver currently accepted standards care. The study's findings show that the number of years a doctor has been in practice may decrease the likelihood of the doctor providing technically appropriate care.
Medical problems contributed to about half of all bankruptcies, involving 700,000 households in 2001, according to a story published today. Families with children were especially hard hit.
In a comparison of complementary and alternative medicine (CAM) use by adults in 1997 and 2002, researchers from Harvard Medical School found more than one in three U.S. adults (36.5 and 35.0 percent, respectively) used at least one form of CAM.
Researchers have discovered an enzyme that plays an important role in controlling which genes will be turned on or off at any given time in a cell. The novel protein helps orchestrate the patterns of gene activity that determine normal cell function. Their disruption can lead to cancer.
A new study provides evidence that a herpes vaccine developed by a Harvard Medical School researcher is a strong candidate for testing in humans. The study compared three different experimental vaccines for herpes simplex virus 2 (HSV-2), the virus that causes most cases of genital herpes.
The Center for Health and the Global Environment at Harvard Medical School will present Bill Moyers with the 2004 Global Environmental Citizen Award on Wednesday, December 1.
Most genes carry out their tasks by making a product"“a protein or enzyme. The new gene, found in yeast, does not produce a protein. It performs its function, in this case to regulate a nearby gene, simply by being turned on.
