LSU astronomers discover origin of thermonuclear supernova
LSU astronomers recently discovered the solution to a long-standing fundamental problem of astrophysics: what produces thermonuclear, or Type Ia, supernovae, which are tremendous explosions where the light is often brighter than a whole galaxy? View More (2012-01-12)
Scaffold gradients: Finding the right environment for developing cells
People often have strong opinions on the "right" firmness of mattresses for themselves, and, as it turns out, some cell types have similar preferences for their support structures. View More (2010-05-28)
Mayo Clinic researchers use magnetic attraction to improve stents, reduce blood clot risk
Mayo Clinic heart researchers have devised a new strategy to improve the effectiveness and safety of heart stents, which are used to open narrowed blood vessels and have been the recent subject of clotting concerns. View More (2006-11-03)

New class of stem cell-like cells discovered offers possibility for spinal cord repair
The Allen Institute for Brain Science announced today the discovery of a new class of cells in the spinal cord that act like neural stem cells, offering a fresh avenue in the search for therapies to treat spinal cord injury and disease. View More (2011-09-16)
Using Nanoparticles, In Vivo Gene Therapy Activates Brain Stem Cells
Using customized nanoparticles that they developed, University at Buffalo scientists have for the first time delivered genes into the brains of living mice with an efficiency that is similar to, or better than, viral vectors and with no observable toxic effect, according to a paper published this week in Proceedings of the National Academy of Sciences.

Are there too many stem cell journals?
Stem cells differentiate and proliferate; so do stem cell journals. Are there too many stem cell research journals? View More (2010-08-18)
Finally, an excuse for pregnant women to eat bacon and eggs
If you're pregnant and looking for an excuse to eat bacon and eggs, now you've got one: a new research study published in the January 2010 print issue of the FASEB Journal by a team of University of North Carolina researchers shows that choline plays a critical role in helping fetal brains develop regions associated with memory. Choline is found in meats, including pork, as well as chicken eggs. View More (2010-01-05)
'Grow your own transplant' may be possible for men with type 1 diabetes
Men with type 1 diabetes may be able to grow their own insulin-producing cells from their testicular tissue, say Georgetown University Medical Center (GUMC) researchers who presented their findings today at the American Society of Cell Biology 50th annual meeting in Philadelphia.

Transforming skin cells into stem cells using a molecular toolkit
In an effort to sidestep the ethical dilemma involved in using human embryonic stem cells to treat diseases, scientists are developing non-controversial alternatives: In particular, they are looking for drug-like chemical compounds that can transform adult skin cells into the stem cells now obtained from human embryos.

Immune deficiency linked to a type of eye cancer
The incidence of squamous cell eye cancer is greater among kidney transplant patients and people with human immunodeficiency virus (HIV) than the general public, which suggests the disease is associated with immune deficiency. View More (2007-08-15)
Massive Black Hole Smashes Record
Using two NASA satellites, astronomers have discovered the heftiest known black hole to orbit a star. The new black hole, with a mass 24 to 33 times that of our Sun, is more massive than scientists expected for a black hole that formed from a dying star. View More (2007-10-31)
UCLA researchers discover new disorder that causes chronic diarrhea in children

Human taste cells regenerate in a dish
Following years of futile attempts, new research from the Monell Center demonstrates that living human taste cells can be maintained in culture for at least seven months. View More (2011-04-06)
How does a zebrafish grow a new tail?
If a zebrafish loses a chunk of its tail fin, it'll grow back within a week. Like lizards, newts, and frogs, a zebrafish can replace surprisingly complex body parts. A tail fin, for example, has many different types of cells and is a very intricate structure. It is the fish version of an arm or leg. View More (2006-12-27)
The secret of internal bliss revealed
Scientists now know for sure how cannabis works in the brain. By studying naturally occuring cannabinoids they have found that cannabis 'speaks' to nerve cells instructing them to stop releasing their chemical neurotransmitters so dumbing down their effects. The upside is that it makes cannabis effective for treatment of MS but it also has a detrimental effect on short-term memory. Dr Maurice... View More (2001-04-03)
Can pathological techniques help identify primary colorectal signet ring cell carcinoma?
Primary colorectal signet ring cell carcinoma is a rare but distinctive malignancy of the large bowel. More than 96% of signet ring cell carcinomas arise in the stomach, with the rest arising from other primary organs. View More (2008-05-21)
'Smart scaffolds' may help heal broken hearts
Imagine new treatments for heart disease or muscle loss that direct the body to repair damaged tissue rather than helping it cope with a weakened condition. View More (2009-01-13)
