Alligator egg development at prehistoric oxygen levels
The development of bone structures in alligator eggs raised under varying oxygen concentrations creates a link to fossil records of the evolution of vertebrates and prehistoric atmospheric oxygen concentrations, according to a paper to be presented at the Earth System Processes 2 meeting in... view more (2005-08-05)

Stem cells found in adult hair follicles may provide alternative to embryonic stem cells
Having recently identified the molecular signature of these epidermal neural crest stem cells in the mouse, their research resolves conflicting scientific opinions by showing that these cells are distinctly different from other types of skin-resident stem cells/progenitors. Their work provides a... view more (2006-12-12)

Donner cannibalism remains unproven
The Donner Party used tea cups and other tableware and ate domestic and wild animals while stranded in the Sierra Nevadas during 1846-47, but all group members may not have resorted to cannibalism.   view more (2006-01-13)

Bone marrow may be source of new egg-cell generation in adult mammals
Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.   view more (2005-07-28)

Nanotubes inspire new technique for healing broken bones
Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing   view more (2005-07-11)

Meet the Earliest Baby Girl ever Discovered!
3.3 million years ago, a three year old girl died in present day Ethiopia, in an area called Dikika. Though a baby, she provides researchers with a unique account of our past, as would a grandmother. Her completeness, antiquity, and age at death combine make this find unprecedented in the history... view more (2006-09-22)

Study finds new type of silicone implant offers more natural looking breasts, low complication rate
A new type of silicone breast implant, currently available to women who agree to be part of a clinical study, offers breast augmentation and reconstruction patients more natural looking breasts with a low complication rate.   view more (2005-10-18)

A plastic pill for periodontal problems
Rutgers scientists today announced a revolutionary new treatment for killing the bacteria that attack gum tissue during periodontal disease, while also promoting healing and the regeneration of tissue and bone around the teeth.   view more (2006-09-15)

Penn study finds hyperbaric oxygen treatments mobilize stem cells
According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body.   view more (2005-12-29)

Mad-cow culprit maintains stem cells
What do mad cow disease and stem cell research have in common? Whitehead Institute scientists have found that the same protein that causes neurodegenerative conditions such as bovine spongiform encephalopathy (mad cow disease) is also important for helping certain adult stem cells maintain... view more (2006-01-31)
