Scientists say they have reversed a bit of bird evolution in the lab and recreated a dinosaur-like snout in developing chickens. “In this work, we can clearly see a comeback of the characteristics which we see in some of the first birds,” says Arhat Abzhanov, an evolutionary biologist at Harvard University. The ancestors of birds […]

Global carbon dioxide (CO2) concentrations have reached a new monthly record of 400 parts per million, according to scientists. The milestone was announced by the US National Oceanic and Atmospheric Administration (Noaa). They said it was the first month that the entire globe broke 400ppm, reaching levels that haven’t been seen for about two million […]
Nanowire–Bacteria Hybrids for Unassisted Solar Carbon Dioxide Fixation to Value-Added Chemicals – WHAT ! ! ! In natural photosynthesis, CO2 is first reduced to common biochemical building blocks using solar energy, which are subsequently used for the synthesis of the complex mixture of molecular products that form biomass. Direct solar-powered production of value-added chemicals from […]
The weather has been weird, and scientists have found that a strange “blob” of warm water is to be blamed. Located off the West Coast, this patch of water is warmer by 2 to 7 degrees Fahrenheit than normal. Nick Bond, a climate scientist for the Joint Institute for the Study of the Atmosphere and […]
