Berkeley, California - The climatic and environmental effects of lava flows and sulfur emissions that lasted for years or decades in earth’s past were likely much less severe than scientists once thought, according to a new study by scientists in Europe and the United States.
Earth not due for a geomagnetic flip

Cambridge, Massachusetts - The intensity of Earth’s geomagnetic field has been dropping for the past 200 years, at a rate that some scientists suspect may cause the field to bottom out in 2,000 years, temporarily leaving the planet unprotected against damaging charged particles from the sun. This drop in intensity is associated with periodic geomagnetic field reversals, in which the Earth’s North and South magnetic poles flip polarity, and it could last for several thousand years before returning to a stable, shielding intensity.

Cambridge, Massachusetts - The most widely used technology for producing X-rays - used in everything from medical and dental imaging, to testing for cracks in industrial materials - has remained essentially the same for more than a century. But based on a new analysis by researchers at MIT and in Singapore, that might potentially change in the next few years.
