A study of the most recent near-reversals of the Earth’s magnetic field by an international team of researchers, including the University of Liverpool, has found it is unlikely that such an event will take place anytime soon. There has been speculation that the Earth’s geomagnetic fields may be about to reverse, with substantial implications, due ...
Scientists have discovered a completely new type of opal formed by a common seaweed that harnesses natural technology by self-assembling a nanostructure of oil droplets to control how light reflects from its cells to display a shimmering array of colors that, until now, has only been seen in the gemstone. The findings, published in Science Advances and ...
For centuries, the prevailing science has indicated that all of the nitrogen on Earth available to plants comes from the atmosphere. But a study from the University of California, Davis, indicates that more than a quarter comes from Earth’s bedrock. The study, to be published April 6 in the journal Science, found that up to 26 ...
Scientists conclude methane-producing microbes date back 3.5 billion years, supporting the hypothesis that they could have contributed to early global warming. Early forms of life very likely had metabolisms that transformed the primordial Earth, such as initiating the carbon cycle and producing most of the planet’s oxygen through photosynthesis. About 3.5 billion years ago, the ...
There is a new method to harvest water from desert air. It seems like getting something for nothing, but you really can get drinkable water right out of the driest of desert air. Even in the most arid places on Earth, there is some moisture in the air, and a practical way to extract that ...
Two Purdue University studies show that urbanization changes storm patterns and rainfall amounts, highlighting the need for urban planning and infrastructure design that considers how the landscape will affect the weather. In two separate papers, teams led by Dev Niyogi, Indiana state climatologist and professor in the departments of Agronomy and Earth, Atmospheric, and Planetary Sciences, studied storm patterns ...
India’s air and water dilemma is becoming ever more serious. Although India is one of the world’s top developing countries, it finds itself in the list of the top polluted nations in the world. In fact, the 15 most polluted cities in the world include 6 cities located in the northern belt of India. Additionally, ...
A study shows that grazing lands are vulnerable to climate change. Some 800 million people around the world depend on livestock that graze on natural vegetation for their livelihoods and food security. In a good season, grasses and other plants flourish, supporting robust herds. In a bad season, the system suffers — as do the people ...
Most of us surely don’t think of mosquitoes as being especially adept at learning. But that may not be the case. In a paper published on January 25 in Current Biology, University of Washington researchers report that they can, in fact, learn to associate a particular odor with an unpleasant mechanical shock akin to being swatted. As a ...
A bizarre underwater phenomenon in Antarctica has been caught on camera. However, be warned, the stunning phenomenon hides a deadly secret. With time-lapse cameras, Hugh Miller and Doug Anderson, for the first time, were able to time record the rare natural event dubbed the “Ice Finger of Death.” The twisting column of ice drives down ...
