NASA’s Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Community-based palliative care – care delivered at home, not the hospital – was associated with a 50 percent reduction in emergency department visits for patients in their last year of life.  The results of an Australian study were published online February 3rd in Annals of Emergency Medicine(“The Association of Community-Based Palliative Care with Reduced Emergency Department…

As a result of climate change, concentrations of the trace element selenium in soils are likely to decrease. Because the selenium content of crops may also be reduced, the risk of selenium deficiency could be increased in many regions of the world. This was shown by a recent study which used data-mining to model the…

Late on Feb. 15, Dineo made landfall in southern Mozambique. By Feb. 17 the storm weakened to a remnant low pressure area when NASA's Terra satellite passed overhead. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Terra captured a visible image that showed the center of the low pressure area over Zimbabwe and clouds…

One morning in February 2015, I felt a rumble. Was it an earthquake? No. It was an explosion at the ExxonMobil oil refinery a few miles away. The refinery is located in the middle of a residential area of Torrance, Calif.

A new scientific paper by a University of Maryland-led international team of distinguished scientists, including five members of the National Academies, argues that there are critical two-way feedbacks missing from current climate models that are used to inform environmental, climate, and economic policies. The most important inadequately-modeled variables are inequality, consumption, and population.
