Trees growing under simulated heat and drought conditions reveal that the negatives of increased atmospheric CO2 levels outweigh the benefits for plants

Environment

Study shows why trees won't benefit much from extra CO2 in the air

One argued silver lining of rising atmospheric carbon dioxide levels is that plants will be better off. But a new study has found that the more extreme heat and drought brought on by climate change would cancel out most of the benefits for trees.

Researchers have evolved E. coli bacteria to eat carbon dioxide from the air

Biology

Directed evolution teaches bacteria to eat carbon dioxide

Researchers have created bacteria that can effectively eat air. By carefully directing the evolution of E. coli in the lab, the team managed to wean them off their preferred diet of sugar, and make the switch to carbon dioxide in the air around them.

Research indicates that stem cells could be used to heal damaged lungs

Respiratory diseases are extremely prevalent, with more than 35 million sufferers in the US alone. Now, a team from the Weizmann Institute of Science has worked to create a new treatment for repairing damaged lung tissue, using the procedure for bone marrow stem cell transplantation as a template.

Stem cell breakthrough may allow same gender couples to create babies

Researchers are claiming a stem cell research breakthrough that would allow a baby to be created from the skin cells of two adults, no matter their gender. From this, scientists have produced precursor cells for sperm or ova that may allow same gender couples to produce offspring.
