Ames Laboratory researcher’s microscale channels steer neurons to rewire damaged nerves
Using microscale channels cut in an ultrathin biodegradable polymer, a researcher at the U.S. Department of Energys Ames Laboratory is working to regrow nerve cells. The technique, which may one day allow the paralyzed to walk and the blind to see, has been proven to work for peripheral nerve regeneration in laboratory rats.
Nerve cells are unlike most other biological tissue. When a
The number of circulating endothelial progenitor cells in an individuals blood –– the precursor cells to those that line the insides of blood vessels –– may be an indicator of overall cardiovascular health, according to research by scientists at the National Heart, Lung, and Blood Institute (NHLBI) and Emory University School of Medicine. The research was published in the Feb. 13 issue of the New England Journal of Medicine.
The endothelial cells lining the blood vessels provide essen
For the first time ever, a University of Alberta researcher has discovered that an animal species has changed its genetic make-up to cope with global warming. In the past, organisms have shown the flexibility–or plasticity–to adapt to their surroundings, but this is the first time it has been proven a species has responded genetically to cope with environmental forces.
Dr. Stan Boutin, from the Department of Biological Sciences at the University of Alberta in Edmonton, has been studying a
Answer one of natural history’s most intractable questions
All of Madagascars living Carnivora (an order of mammals that includes dogs, cats, bears, hyenas and their relatives) descended from a single species that dispersed from Africa to Madagascar, apparently floating across the ocean barrier aboard wayward vegetation about 24 million to 18 million years ago. Previously, scientists believed that Madagascars seven living species of native Carnivora represented two to four
Scientists from the University of Leicester are taking revolutionary research further with the potential to offer new hope for knee-injury victims.
They are following up international research that aims to improve knee cartilage repair techniques, termed ‘chrondrocyte implantation’. The procedure, developed in Sweden ten years ago, involves growing a patient’s knee cartilage cells in a laboratory, which are then implanted through open knee surgery. Recent exciting developments revolve
