New and controversial transplant operation uses stem cells derived from spare human embryos.
Adding one single gene to yeast dramatically improves bioethanol production from agricultural waste
With the introduction of a single bacterial gene into yeast, researchers have achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the...
Flax and yellow flowers can produce bioethanol
Surplus biomass from the production of flax sheaves, and generated from Brassica carinata, a yellow-flowered plant related to those which engulf fields in spring, can be used to produce bioethanol.
Scientists identify DNA that regulates antibody production
(PhysOrg.com) -- When foreign invaders trip the immune system`s alarm, antibodies need to be specially sculpted to attack them head on. New research now shows that gene segments called enhancers...
