Trace elements such as iron, manganese and zinc are an integral part of the biogeochemical processes on the Earth's surface.

Princeton researchers have confirmed a theory first put forward in 1929 by the Nobel laureate Felix Bloch, who theorized that certain kinds of materials, when drawn down to a very low electron density, would spontaneously magnetize.

Since the coronavirus pandemic began in the spring, many people have only seen their close friends and loved ones during video calls, if at all.

Within a single cell, thousands of molecules, such as proteins, ions, and other signaling molecules, work together to perform all kinds of functions — absorbing nutrients, storing memories, and differentiating into specific tissues, among many others.

Plastic pollution is ubiquitous today, with microplastic particles from disposable goods found in natural environments throughout the globe, including Antarctica.

New technology can quickly and accurately monitor glucose levels in people with diabetes without painful finger pricks to draw blood. 

Researchers examining subglacial waters both from Antarctica and Greenland found that these waters have higher concentrations of important, life-sustaining elements than previously thought, answering a big unknown for scientists seeking to understand the Earth’s geochemical processes.

“The data from an Antarctic lake is particularly exciting,” said Florida State University postdoctoral fellow Jon Hawkings. “Most people tend to think of Antarctica as just ice, but we’ve known about these lakes underneath the glaciers in Antarctica for 40 years and over 400 of them have currently been identified. Some scientists refer to the subglacial environment in Antarctic as the world’s largest wetland. The challenge for scientists is it’s just extremely difficult to sample them.”

Hawkings, along with colleagues at Florida State and Montana State University, has published a new study this week in the Proceedings of the National Academy of Sciences exploring these subglacial waters.

A class of materials called metal organic frameworks, or MOFs, has attracted considerable interest over the last several years for a variety of potential energy-related applications — especially since researchers discovered that these typically insulating materials could also be made electrically conductive.

New research from the University of Stirling into the effectiveness of international conservation projects could help to save endangered species from extinction.

Eupinions carried out the survey in September for the Europe's Stories project at St Antony's College, covering all 27 EU member states and the UK.
