Because of the global warming, there are more and larger melt ponds

When spring arrives in the Arctic, both snow and sea ice melt, forming melt ponds on the surface of the sea ice. Every year, as global warming increases, there are more and larger melt ponds. Melt ponds provide more light and heat for the ice and the underlying water, but now it turns out that […]

New theory explains that despite extreme heat,and how Earth’s inner core remains solid

Even though it is hotter than the surface of the Sun, the crystallized iron core of Earth remains solid. A new study from KTH Royal Institute of Technology in Sweden may finally settle a longstanding debate over how that’s possible, as well as why seismic waves travel at higher speeds between the planet’s poles than […]

Supercomputer simulations confirm observations of India/Pakistan heat waves in 2015

A paper published during the American Geophysical Union (AGU) fall meeting in San Francisco points to new evidence of human influence on extreme weather events this week. Three researchers from Lawrence Berkeley National Laboratory (Berkeley Lab) are among the co-authors on the paper, which is included in “Explaining Extreme Events of 2015 from a Climate […]

Widespread evidence of prehistoric dairying discovered along the Mediterranean coast

An inter-disciplinary team of scientists and archaeologists have discovered widespread evidence of prehistoric milk production in southern Europe. The study uncovered evidence that humans have been utilising milk and dairy products across the northern Mediterranean region from the onset of agriculture — some 9,000 years ago. The importance of meat and dairy production in the […]

New technology aims to make photovoltaic cells 70% more efficient

Researchers at the Technion-Israel Institute of Technology have developed a technology that could improve the efficiency of photovoltaic cells by nearly 70 percent. The breakthrough could be a key for overcoming current technological limitations to harnessing solar power to meet the world’s energy consumption demands. The study was conducted at the Excitonics Lab, headed by […]

A rising tide of heart attacks followed Hurricane Katrina

Ten years after Hurricane Katrina hit New Orleans, hospital admissions for heart attacks in the city were three times higher than they were before the storm, according to research presented at the American Heart Association’s Scientific Sessions 2016. “After Hurricane Katrina devastated our city, the cardiology department found that we had very busy on-call nights,” […]

Words and bones tell a similar story about deep history

University of Tübingen researchers have found evidence that common descent of human populations is reflected both in their cranial features and their linguistic affiliations over vast geographic distances. The formation of different languages and language groupings appears to have happened in the same broad period and geographical locations as the development of facial features in […]

Indonesian fires exposed 69 million to ‘killer haze’

Wildfires in Indonesia and Borneo exposed 69 million people to unhealthy air pollution and are responsible for thousands of premature deaths, new research has shown. The study, published today in Scientific Reports, gives the most accurate picture yet of the impact on human health of the wildfires which ripped through forest and peatland in Equatorial […]

Salty snow could affect air pollution in the Arctic

In pictures, the Arctic appears pristine and timeless with its barren lands and icy landscape. In reality, the area is rapidly changing. Scientists are working to understand the chemistry behind these changes to better predict what could happen to the region in the future. One team reports in ACS’ Journal of Physical Chemistry A that […]
