[ad_1] Scientists have long envisioned building tiny robots capable of navigating environments inaccessible or too dangerous for humans – but finding ways to keep them energized and moving has been impossible to achieve. A team from the University of Southern California has now made a breakthrough by building an 88 milligram (three hundredths of an … Read more
[ad_1] Research published in the journal Earth System Dynamics highlights disparities between the most sensitive climate change models and temperature observations since the 1970s. Scientists at the University of Exeter have studied data from complex climate models , comparing them to records of global warming. Recent developments in climate modeling have produced worrying predictions for … Read more
[ad_1] According to researchers at the University of Illinois, a supernova 65 light years from Earth likely caused a mass extinction event during the Late Devonian period, 359 million years ago. Researchers have found radioactive isotopes in rocks that may be able to confirm such an event, as detailed in a new article published in … Read more
[ad_1] On August 16, a space rock the size of a car flew over Earth at a distance too close for comfort – about 1,830 miles. What’s even more bewildering is that NASA never saw her until after it happened. It was the closest ever recorded, according to a Business Insider report cited, according to … Read more
