Key to Kibbitzer 68: Until now v. To date

1. To date, scientists have identified eight Hox genes in the fruit fly and more than 40 in the mouse. The DNA sequences of these genes are so similar that they are unlikely to have evolved independently.
2. In July last year the Social Market Foundation published the most penetrating study to date on the reform of legal aid.
3. The house has made the reputation of its young and (until now) relatively unknown architect, Anthony Hudson
4. The most important advantage the device has over previous sensors is that it can be used to measure glutamate changes in "real time", a feat that has been impossible until now.
5. "Our investigations to date have found no medical or scientific evidence of a Gulf War syndrome, or any medical condition peculiar to service in the Gulf" Mr Soames said.
6. Grose has produced what must be the most comprehensive account to date of the CIA’s deeds and misdeeds during the cold-war years.
7. Nylon, a fabric that, until now, has been looked down upon as old-fashioned and sweaty, has been given a new lease of life.
8. Until now the New Zealand flatworm, which consumes native earthworms, was thought to have no natural predator in Britain and to be unstoppable in its gradual spread through the country. However, scientists at the Institute of Cell, Animal and Population Biology at Edinburgh University have found by chance that the larvae of some common beetles will feed on the alien.
