Work-related stress is not directly linked to the development of colorectal, lung, breast or prostate cancers, but can cause other contributing factors, according to a new study published on bmj.com
Around 90 per cent of cancers are linked to environmental exposures and whilst some exposures are well recognised (such as UV radiation and tobacco smoke), others are not (psychological factors such as stress). (more…)
Complex organic compounds, including many important to life on Earth, were readily produced under conditions that likely prevailed in the primordial solar system. Scientists at the University of Chicago and NASA Ames Research Center came to this conclusion after linking computer simulations to laboratory experiments.
Fred Ciesla, assistant professor in geophysical sciences at UChicago, simulated the dynamics of the solar nebula, the cloud of gas and dust from which the sun and the planets formed. Although every dust particle within the nebula behaved differently, they all experienced the conditions needed for organics to form over a simulated million-year period. (more…)
