Scientists discover how Nipah virus enters cells
Researchers at UCLA and USUHS discovered the Ephrin-B2 receptor as the doorway for Nipah and Hendra viruses to enter cells. This finding promises to lead to better understanding of how these viruses cause disease in humans and animals, ultimately aiding in vaccine and treatment development.
One gene links newborn neurons with those that die in diseases such as Alzheimer's
A study found that gene UCHL1 is consistently low in replaceable neurons, associated with increased survival and reduced neuronal death. Researchers discovered UCHL1 levels increase when birds sing, suggesting a link to improved neuron replacement.

Scientists achieve self-assembly of spider silk fiber in insect cells
Researchers successfully produce spider silk fibers in insect cell cultures using genetic engineering, opening the way for commercial development. The fibers possess chemical resistance characteristics similar to those produced by spiders.
New brain cells develop during alcohol abstinence, UNC study shows
Researchers at UNC's Bowles Center discovered that new brain cells develop during alcohol abstinence, reversing damage caused by chronic alcohol dependency. The study found a twofold burst in brain cell proliferation after four-to-five weeks of abstinence.
K-State professor combines love of teaching, research to examine eye development
Researcher Conrad focuses on elucidating molecular steps in embryonic animal eyes to develop new treatments for corneal transplants. His team uses mass spectrometry to analyze polysaccharides and uncover the influence of sugars on cell decisions.
A big surprise: Young nerve cells can rewind their developmental clocks
In a groundbreaking study, researchers at NYU School of Medicine found that young nerve cells can rewire their developmental timeline, defying long-held assumptions about brain development. This discovery opens up new possibilities for generating neural tissue for replacement therapies.
Research on spleen cells could yield potential cure for Type 1 diabetes
A new study by the Society for Women's Health Research has found that spleen cells can rapidly regrow adult islet cells without embryonic stem cells. This breakthrough discovery opens up a new approach to treating Type 1 diabetes, which develops when the immune system attacks insulin-producing islet cells.
Regeneration of insulin-producing islets may lead to diabetes cure
Researchers have discovered that spleen cells can regenerate insulin-secreting islets in mice with Type 1 diabetes, potentially leading to a cure. The study shows that these cells can grow from both the recipient's own cells and donor cells, opening up new approaches to diabetes treatment.
Transparent fish provide window on blood formation and marrow transplantation
Zebrafish provide a unique window into blood cell development, allowing researchers to distinguish individual cell types and transplant genetically altered cells. The technique enables the study of cellular defects in mutant fish, which can inform human transplantation strategies.
Name that tune
Researchers found that specific cells in the bird's brain become 'tuned' to what the bird is learning, responding strongly to familiar songs and motifs. The study suggests that experience modifies the brain to highlight important motifs, allowing birds to recognize individual songs.
Scientists observe nanosize microtubules 'treadmilling' across plant cells
Researchers at Stanford University have witnessed the birth and growth of individual microtubules in plant cells, discovering a unique process called treadmilling. This process involves the addition and removal of protein subunits from the microtubule ends, leading to its movement across the cell.
Sometimes no result is good result for science
Researchers discovered that the removal of MTase1, a viral protein, did not impact virus replication rates in tissue culture. This finding suggests that proteins essential to virus function may be more complex than previously thought, with implications for understanding virus behavior and potential applications in pest control.
1st evidence that nuclear transplantation ('therapeutic cloning') can eliminate tissue rejection
Researchers at Advanced Cell Technology successfully transplanted cloned tissues into animals without rejection. The study's findings suggest that nuclear transplantation could provide a limitless supply of immune-compatible cells and organs for regenerative therapies, tackling one of the major challenges in transplantation medicine.
Two genes are better than one: Combination approach selectively kills pancreatic cancer cells
Researchers at Columbia University Irving Medical Center have discovered a combination of two genes that selectively kill pancreatic cancer cells in test tube experiments. The mda-7 protein and K-ras antisense DNA combination prevents tumor growth in animals, offering a potential new treatment option for this aggressive disease.

New insight into diet and colon cancer
Researchers found that a fish oil-rich diet protects against colon cancer, while a corn oil-diet appears to promote it. The scientists also discovered how cancer spreads among cells in the colon, with a new understanding of cell damage varying from bottom to top within crypts.
