Phys.org / Online review structure, not just sentiment, predicts what readers find helpful
A study of nearly 200,000 Amazon reviews shows that the usefulness of online product reviews depends not only on what is said, but on how the information is structured. The researchers, from the Universities of Cambridge ...
Phys.org / Parabolic flight test shows lasers can propel graphene aerogels in microgravity
Lasers could one day steer solar sails and adjust a satellite's position in outer space, thanks to graphene. An experiment on a gravity rollercoaster ride showed how this innovative material has the potential to revolutionize ...
Phys.org / Light-driven method enables sustainable production of porous semiconducting polymers
Researchers at Koç University have developed a light-driven method to produce porous semiconducting polymers under ambient conditions without the need for metal catalysts. The study, led by Prof. Dr. Önder Metin from the ...
Phys.org / Tropical cyclone Narelle struck three major reef systems in one epic trek
Coral reefs are important in many ways, but they also play a major role in protecting much of the world's coastlines from erosion by blocking up to 90% of incoming wave energy. During a tropical cyclone, the waves breaking ...
