Living mulch functions like mulch on any farm or garden except — it’s alive. No, it’s not out of the latest horror movie; living mulch is a system farmers can use to benefit both profits and the soil. While the system has been around for a while, scientists at the University of Georgia are making it more efficient and sustainable.

To make natural gas and biogas suitable for use, the methane has to be separated from the CO?. This involves the use of membranes: filters that stop the methane and let the CO? pass through. Researchers at KU Leuven have developed a new membrane that makes the separation process much more effective.

A study that used DNA tests to analyse the scats of one of the world’s most numerous albatrosses has revealed surprising results about the top predator’s diet.

Using a Lidar, a laser ranging instrument, at the University’s Bayfordbury Observatory near Hertford, the team monitored the height of the particles throughout the day. Laser pulses reflected from the particles show their arrival around midday, their growing height in the atmosphere, and their eventual departure in the evening.

The atmospheric profile was measured every second, allowing the changes in the particle layering to be observed throughout the day. The particles responsible for the red sky are seen as a diagonal stripe in the profile sequence. The layer of dust arrived over Hertford around 11:00 GMT at 1 km altitude, drifted past over the next 6 hours at progressively higher altitudes, and reached 2-3 km altitude by the time it moved away from Hertford around 18:00 UTC.

Resilient species of coral can move to inhospitable areas and lay the foundations for new reefs, a study shows.
