Because of their ability to differentiate into any cell type, stem cells have been thought to play an important role in limb regeneration processes. But new research has found that in zebrafishes that have lost their fins, the regrowing of the lim

Now that the ten-year effort to take stock of the diversity of life in the oceans came to a triumphant end late last year, researchers involved in the Census for Marine Life are reflecting on the project's shortcomings. Of main concern is the futu
Although pathogens have long been suspected to play a role in the neurodegeneration of Parkinson's and related diseases (see our December 2010 feature), very little is understood about the mechanics of the process. Specifically, scientists have been
Tiny fossil tracks embedded in a California rock formation that was once part of an ancient river may be evidence that freshwater ecosystems arose around 100 million years earlier than what is generally believed. The existing fossil record dates t

Chronic users of acetaminophen (Tylenol) have a higher risk of developing blood cancer, according to a study published this week in the Journal of Clinical Oncology. The increased risk is small, but the finding adds to a growing body of literature th
Gay men are nearly twice as likely to report that they've had cancer as heterosexual men, according to a US health survey published in Cancer. Lesbians and bisexual female cancer survivors also report more health problems than heterosexual women in r
There's good, stem cell-related news for another organ this week -- the lung. Researchers say they have found lung stem cells, which may hold therapeutic value for repairing damaged respiratory tissue, according to a study published this week in the
Researchers have found a way to reprogram cells from mouse tails to behave like mature liver cells, which appear to be able to repair damaged livers
In a feat of computational biology, researchers design novel proteins capable of neutralizing a key influenza protein
