Smiling does not necessarily indicate that we are happy, according to new research at Brighton and Sussex Medical School (BSMS). 

The MRSA staphylococcus is an example of a pathogen, the likes of which are often called superbugs. These are resistant to most antibiotics and can cause serious infections.

Scientists from Waseda University, the National Defense Medical College, and the Japan Science and Technology Agency developed a new bioadhesive, wirelessly-powered light-emitting device which could better treat cancers in delicate organs.

To curb greenhouse gas emissions, nations, states, and cities should aim for a mix of fuel-saving, flexible, and highly reliable sources.

Wind and solar farms are known to have local effects on heat, humidity and other factors that may be beneficial – or detrimental – to the regions in which they are situated.

Starting in 2011, the National Park Service removed two obsolete dams from the Elwha River in Olympic National Park, Washington.

The Global Precipitation Measurement mission or GPM satellite passed over Hurricane Olivia and found heaviest rain in a tight ring around the eye.

Hydropower can generate electricity without emitting greenhouse gases but can cause environmental and social harms.

A region of West Antarctica is behaving differently from most of the continent’s ice: A large patch of ice there is thickening, unlike other parts of West Antarctica that are losing ice. Whether this thickening trend will continue affects the overall amount that melting or collapsing glaciers could raise the level of the world’s oceans.

56 million years ago, the Earth experienced an exceptional episode of global warming. In a very short time on a geological scale, within 10 to 20’000 years, the average temperature increased by 5 to 8 degrees, only returning to its original level a few hundred thousand years later. Based on the analysis of sediments from the southern slope of the Pyrenees, researchers from the University of Geneva (UNIGE) measured the impact of this warming on river floods and the surrounding landscapes: the amplitude of floods increased by  a factor of eight - and sometimes even by a factor of 14 -, and vegetated landscapes may have been replaced by arid pebbly plains. Their disturbing conclusions, to be discovered in Scientific Reports, show that the consequences of such global warming may have been much greater than predicted by current climate models.
