Detecting nanoplastics in fractions of a second using modified Raman spectroscopy
Microplastics are tiny, barely visible plastic particles that can harm the environment, for example, if they are eaten by animals. However, it has been difficult to assess the effect of even smaller particles, which can hardly be detected using conve.....»»
Video shows an iMac G3 that was modified with a touchscreen back in 1999
The iconic iMac G3 was announced by Steve Jobs almost 26 years ago, on May 6, 1998. For its time, the iMac was considered a revolution in industrial design with its all-in-one construction in translucent plastic. It also ditched technologies like ser.....»»
Vacuum cleaner-effect in fungi can hold nanoplastics at bay
Using micro-engineered soil models, researchers at Lund University in Sweden have investigated the effect of tiny polystyrene particles on bacteria and fungi. While these nanoplastics reduced both bacterial and fungal growth, the fungus actually mana.....»»

Laser-scribed graphene for sensors
With the development of the information era, sensors capable of transmitting and detecting information have become the leading way to obtain information. Therefore, building a sensor system with a wide detection range, high sensitivity and fast respo.....»»
Gravitational distortion of time helps tell modified gravity apart from a dark force
With his theory of General Relativity in 1915, Albert Einstein revolutionized how we think about our universe. Rather than the cosmos simply providing the room for the planets and stars to orbit each other, space and time themselves were now dynamica.....»»
