The discovery that lipids can serve as antigens first stunned the immunological community a decade ago.
For most, immunity is simply there when you need it, like the umbrella sitting by the door.
Human embryonic stem cells remain the focus of an ever-intensifying public debate that blurs the limits of biology, confusing cultured tissues with children, and blastocysts descended from fertilized ova with those derived from somatic cell nuclei.
Adult human stem cells may offer the opportunity to use one of biomedical science's most promising technologies without the ethical dilemmas of embryonic cells.
Your stem cells have just arrived.
The air at the Wellcome Trust Sanger Institute in Hinxton, near Cambridge, fairly hums with electricity.
It's more than simple databasing, mining, or in silico experimentation.
Three decades and 6,000 papers since the term was first coined, scientists are still debating the mechanisms of long-term potentiation (LTP).1 Defined in 1973 as an increase in synaptic strength following experimentally induced high-frequency stimulation,2 LTP has been consistently controversial. Now at last, "There is a consensus beginning to emerge," says Columbia University Nobel laureate, Eric Kandel, as years of research have begun to make sense of what once seemed irreconcilable contradict
