  • LED & LIGHTING quality evaluation the new DELTAOHM SpectroRadiometer HD30.1

    LEDs cannot be manufactured with consistent optical properties as a result of the production processes involved. Brightness and color can vary substantially from component to component even in the same production batch. This is why LEDs have to be tested during production and in their final application. Comprehensive optical characterization is also essential during research and development of ...

  • Rainforest monitoring network deployed in Amazon

    Using open-access software and power saving technologies, researchers have developed an easily deployed, low-cost network for monitoring large areas of the Amazon rainforest. This Peruvian study shows that environmental information, such as soil moisture and rates of photosynthesis, can be recorded and uploaded to the internet without having to make repeated visits to remote areas. The Amazon ...

  • Sunscreen identified as major cause of coral bleaching

    New research highlights the harmful effects of sunscreens on coral reefs. The ultra-violet (UV) filters, used to protect skin from the harmful effects of sun exposure, caused bleaching of coral reefs even at very low levels. In areas exposed to high levels of human activity, sunscreens may now be posing a significant risk to marine life. Coral reefs are among the most biologically productive and ...
