Story at-a-glance − An independent review of 800 studies concluded neonicotinoids are also harming birds, earthworms, snails, and other invertebrates USDA does not include seed treatments or Bt crops in Continue reading
Team apply new procedure to rapidly induce nerve regeneration in mammals
American scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. Their results are published today in the Journal of Neuroscience Research.
“We have developed a procedure which can repair severed nerves within minutes so that the behavior they control can be partially restored within days and often largely restored within two to four weeks,” said Professor George Bittner Continue reading
The picture shows two 9-month-old mice from the study. The one on the right received the drug to eliminate senescent cells (from the NYT, 2 November, 2011, taken by Jan van Deursen).
Never mind living to 120; what we want is to live healthy to whatever age biology allotted us. Age is the major risk factor for most cancers and for chronic diseases like arthritis. Why is it? Evolutionary biologists tell us that this is nature’s way of clearing us off the stage, so as not to compete with the young for resources. Maybe. I find this theory a bit unsatisfying, if for no other reason than the fact that lower species, Continue reading
