Artificial materials reconstruct porpoise's echolocation

Over millions of years, porpoises have developed powerful biosonar with high accuracy and intelligence to detect and track prey in noisy underwater environments. The sound source in a porpoise is about one half of the wavelength ...

A novel tool to probe fundamental matter

Identifying elementary constituents of matter including quarks, bosons and electrons, and the manner by which these particles interact with each other, constitutes one of the greatest challenges in modern physical sciences. ...

Major steps forward in understanding neutrino properties

In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran Sasso Underground Laboratory in Italy is looking for signs of neutrinoless double beta decay. The experiment has the greatest ...

A new method for quantifying crystal semiconductor efficiency

Japanese scientists have found a new way to detect the efficiency of crystal semiconductors. For the first time ever, the team used a specific kind of photoluminescence spectroscopy, a way to detect light, to characterize ...

A heavyweight candidate for dark matter

Almost a quarter of the universe stands literally in the shadows. According to cosmologists' theories, 25.8% of it is made up of dark matter, whose presence is signaled essentially only by its gravitational pull. What this ...

Applying machine learning in intelligent weather consultation

Weather forecasting is a typical problem of coupling big data with physical-process models, according to Prof. Pingwen Zhang, an academician of Chinese Academy of Sciences, Director of the National Engineering Laboratory ...
