Cell surface receptors are all 'talk' in T cell stimulation
Understanding the mechanisms that drive healthy immune responses is important when it comes to combating autoimmune diseases, which occur when cells that should attack invading organisms turn on the body instead.   view more (2008-06-13)

QBI neuroscientists make Alzheimer's disease advance
Queensland Brain Institute (QBI) neuroscientists at UQ have discovered a new way to reduce neuronal loss in the brain of a person with Alzheimer's disease.   view more (2008-06-10)

Simple membranes could have allowed nutrients to pass into primitive cells
When the first cells developed, how could they bring molecules from the environment into their living interior without the specialized structures found on the modern cell membrane?   view more (2008-06-05)

Human stem cells show promise against fatal children's diseases
Scientists have used human stem cells to dramatically improve the condition of mice with a neurological condition similar to a set of diseases in children that are invariably fatal, according to an article in the June issue of the journal Cell Stem Cell.   view more (2008-06-05)

Public funding impacts progress of human embryonic stem cell research
Bolstered by supportive policies and public research dollars, the United Kingdom, Israel, China, Singapore and Australia are producing unusually large shares of human embryonic stem cell research, according to a report from the Georgia Institute of Technology in the June 2008 issue Cell Stem Cell.   view more (2008-06-05)

Mammalian neurogenesis breaks into the most static brain region
ifteen years ago, the discovery of adult neurogenesis (the production of new neurons) in the highly static, non-renewable mammalian brain was a breakthrough in neuroscience.   view more (2008-06-04)

U of M Sets Course For Cure of Fatal Childhood Skin Disease
Physicians at the University of Minnesota and University of Minnesota Children's Hospital, Fairview have set the path to a cure for a young boy's fatal genetic skin disease, recessive dystrophic epidermolysis bullosa (RDEB), by using a cord blood and bone marrow transplant. Nate Liao, a... view more (2008-06-04)

Gene that magnetically labels cells shows potential as imaging tool
Mammalian cells can produce tiny magnetic nuggets after the introduction of a single gene from bacteria, scientists have found. The gene MagA could become a valuable tool for tracking cells' movement through the body via magnetic resonance imaging (MRI), says Xiaoping Hu, PhD, professor of... view more (2008-06-04)

Brain cells help neighboring nerves regenerate
Researchers have uncovered a completely unexpected way that the brain repairs nerve damage, wherein cells known as astrocytes deliver a protective protein to nearby neurons.   view more (2008-05-28)

Scientists image a single HIV particle being born
A mapmaker and a mathematician may seem like an unlikely duo, but together they worked out a way to measure longitude - and kept millions of sailors from getting lost at sea.   view more (2008-05-27)

Origin of cells for connective tissues of skull and face challenged
With improved resolution, tissue-specific molecular markers and precise timing, University of Oregon biologist James A. Weston and colleagues have possibly overturned a long-standing assumption about the origin of embryonic cells that give rise to connective and skeletal tissues that form the base... view more (2008-05-27)

UCLA researchers identify leukemia stem cells
Stem cell researchers at UCLA have identified a type of leukemia stem cell and uncovered the molecular and genetic mechanisms that cause a normal blood stem cells to become cancerous.   view more (2008-05-27)

Researchers find roadmap to next-generation cancer therapies
Pinpointing new targets for cancer treatments is as difficult as finding a needle in a haystack, yet a University of Rochester team has discovered an entire novel class of genes they believe will lead to a greater understanding of cancer cell function and the next generation of effective and less... view more (2008-05-27)

Protein that provides innate defense against HIV could lead to new treatments
By identifying a protein that restricts the release of HIV-1 virus from human cells, scientists believe they may be closer to identifying new approaches to treatment. The research is published in the advance online edition of Nature Medicine.   view more (2008-05-27)

Dual functions of gene revealed, for better and for worse
Researchers at WEHI have pinpointed the function of a potent cancer gene. The gene, known as "ERG", has long been associated with a range of human malignancies, including leukemia and sarcoma. American scientists showed in 2005 that ERG is mutated in more than half of all prostate... view more (2008-05-27)

Researchers demonstrate 'avalanche effect' in solar cells
Researchers at TU Delft and the FOM Foundation for Fundamental Research on Matter have found irrefutable proof that the so-called avalanche effect by electrons occurs in specific, very small semiconducting crystals.   view more (2008-05-27)

OHSU Discovery May Lead to Early Cancer Detection
OHSU pancreatic cancer expert Brett Sheppard, M.D., and colleagues in the OHSU Oregon Stem Cell Center, have developed antibodies that recognize pancreatic cancer; Sheppard is presenting these findings this week during Digestive Disease Week in San Diego.   view more (2008-05-23)

USC stem cell study sheds new light on cell mechanism
Research from the University of Southern California (USC) has discovered a new mechanism to allow embryonic stem cells to divide indefinitely and remain undifferentiated.   view more (2008-05-22)

Many paths, few destinations: How stem cells decide what they'll be
How does a stem cell decide what specialized identity to adopt - or simply to remain a stem cell? A new study suggests that the conventional view, which assumes that cells are "instructed" to progress along prescribed signaling pathways, is too simplistic.   view more (2008-05-22)

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)

Abnormal 'editing' of gene messages may be a cause of lupus
Researchers at Wake Forest University have uncovered evidence that the abnormal "editing" of gene messages in a type of white blood cell may be behind the development of lupus.   view more (2008-05-20)

Some like it hot! Structure of receptor for hot chili pepper and pain revealed
You can now not only feel the spicy kick of a jalapeno pepper, you can also see it in full 3D, thanks to researchers at Baylor College of Medicine in Houston.   view more (2008-05-20)

For children with sickle cell disease, lung disease is part of the package
Children with sickle cell disease (SCD) have a significantly sharper decline in lung function with age when compared to other children of the same race and age.   view more (2008-05-19)

Traditional herbal medicine kills pancreatic cancer cells, Jefferson researchers report
An herb used in traditional medicine by many Middle Eastern countries may help in the fight against pancreatic cancer, one of the most difficult cancers to treat.   view more (2008-05-19)

MIT creates new material for fuel cells
MIT engineers have improved the power output of one type of fuel cell by more than 50 percent through technology that could help these environmentally friendly energy storage devices find a much broader market, particularly in portable electronics.   view more (2008-05-16)
