A giant 70 million year old fossil of a fish that lived amongst dinosaurs has been discovered in Argentine Patagonia, a team of researchers said on Monday.
Canadian companies that go international are known to be more productive and successful than those that don't.
Currently, low-alloy aluminum is widely used in electrical engineering and machine building. At the same time, it should be noted that modern electrical engineering places very high and in some cases mutually exclusive requirements ...
Over the past few years, fuel cells have become a focal point of research in eco-friendly technology because of their superior abilities to store and produce renewable energy and clean fuel. A typical type of fuel cell gaining ...
Biologists from Lomonosov Moscow State University and HSE University have studied the patterns of flower development in yellow water-lily (Nuphar lutea). They found out that all the floral organs are arranged in cycles (whorls) ...
By tuning the direction of the external magnetic field with respect to the crystallographic axis of the silicon wafer, an improvement of spin lifetime (relaxation time) by over two orders of magnitude was reported in silicon ...
Harvard University's freshman class will be invited to live on campus this fall, while most other undergraduates will be required to learn remotely from home, the Ivy League school announced Monday.
