Researchers have found that the formation and breakup of supercontinents over hundreds of millions of years controls volcanic carbon emissions. The results, reported in the journal Science, could lead to a reinterpretation of how the carbon cycle has evolved over Earth’s history, and how this has impacted the evolution of Earth’s habitability. 

Analysis of natural sparkling mineral water has given scientists valuable clues on how to locate hot water springs.

The organic matter in coal contains polycyclic aromatic compounds (PACs) of varying quantities in diverse soluble and insoluble forms. PACs in coal are of special interest for organic geochemical studies as they have been successfully used as biological marker compounds (biomarkers) and indicators of thermal maturity.However, challenges exist when applying PACs in understanding the organic…

The costs and complications of diabetes could overwhelm healthcare systems in Sub-Saharan Africa and reach US$59.3 billion by 2030 if rates double, according to the Lancet Diabetes and Endocrinology Commission.

We may be capable of finding microbes in space—but if we did, could we tell what they were, and that they were alive?

The giant slug Limax maximus is native to Europe and Asia Minor but has spread widely, being found in North America, South America, North Africa, South Africa, Australia, New Zealand and other regions. The slug is recognized as a notorious pest because it eats agricultural and garden crops.

Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study published in Geophysical Research Letters, a journal of the American Geophysical Union.The study also suggests that the accelerated melting of mountain glaciers in recent decades may explain a phenomenon that has…

Time is of the essence when treating a patient undergoing a heart attack. Cardiac surgeons attempt to quickly stabilize the heart by applying reperfusion, a technique that restores oxygen to the heart by opening up blocked vessels with balloons and stents. While reperfusion can restore cardiac function, such sudden infusions of oxygen can also further…

As severe weather brewed in the Texas panhandle late in the afternoon of May 16,  NOAA National Weather Service forecasters alerted residents in parts of western Oklahoma about the potential for large hail and damaging tornadoes that evening, particularly in the area around Elk City.Ninety minutes later, a dangerous, rain-wrapped EF-2 tornado struck the small…

From indoor lighting to outdoor street lamps, our world is made brighter by artificial light. But the light that we perceive to be constant, actually fluctuates.A University of Toronto computer scientist and researchers from the Technion-Israel Institute of Technology are studying electrical grids for cities, creating a camera that records the city's lights at a…
