The mice that received the bacteria from the obese twins became obese; the mice that […]

Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]

In the sci-fi movie Armageddon, astronauts intercept a killer asteroid heading for Earth, saving mankind. NASA is taking the first step to develop the technology to do just that, by planning a mission to slightly alter an asteroid’s orbit. The mission will also serve as an initial test of a solar-electric propulsion system and other technologies essential for a manned […]
Read moreRadiation from medical scans
Patients are getting larger and perhaps even dangerous doses of radiation from the growing number of advanced medical-imaging tests being ordered by doctors, a new study says. Researchers at the University of California, San Francisco, analyzed data from millions of patients who received medical treatment between 1996 and 2010. They found that the number of patients who underwent CT scans […]
