Scientists grow solar cell components in tobacco plants

(PhysOrg.com) -- Over billions of years, plants have evolved very efficient sunlight-collecting systems. Now, scientists are trying to harness the finely tuned systems in tobacco plants in order to use them as the building ...

Scientists tweak photosynthesis to boost crop yield

Researchers report in the journal Science that they can increase plant productivity by boosting levels of three proteins involved in photosynthesis. In field trials, the scientists saw increases of 14 percent to 20 percent ...

Urban sparrows find new use for cigarette butts

Cigarette butts are widely reviled as an urban nuisance but birds in Mexico City see them as a boon, apparently using them to deter parasites from their nests, scientists say.

Engineered tobacco plants have more potential as a biofuel

Researchers from the Biotechnology Foundation Laboratories at Thomas Jefferson University have identified a way to increase the oil in tobacco plant leaves, which may be the next step in using the plants for biofuel. Their ...

Plant engineered for more efficient photosynthesis

(Phys.org) —A genetically engineered tobacco plant, developed with two genes from blue-green algae (cyanobacteria), holds promise for improving the yields of many food crops.

Tests underway for new HIV drug farmed from GM tobacco plants

A clinical trial of a potential Human Immunodeficiency Virus (HIV) drug farmed from genetically modified (GM) tobacco plants has at long last got underway in the United Kingdom. The beginning of the trial follows several ...
