A new group of ceramic materials could lead to more reliable and clearer microwave communication signals, according to engineers at South Bank University, London, speaking at the Institute of Physics Congress at Heriot-Watt University on Wednesday 26 March.

A small ceramic component made from a dielectric material is fundamental to the operation of filters and oscillators in several microwave systems, such as satellite TV receivers, military radar systems, Global Positioning System (GPS) dev

Dirt, dust and grime are familiar to city dwellers. But tiny airborne particles produced by road traffic, especially in highly polluted urban areas, can be a risk to health. Just how much of a risk is the subject of a talk to be given by Birgit Krausse, of the Institute of Energy and Sustainable Development at De Montfort University Leicester, at the Urban Air conference in Prague on Wednesday 26 March. Her findings suggest that current air-quality standards ignore a major component of pollution tha

Researchers at Harper Adams University College, Shropshire, believe a ‘memory’ in the climate system could be tapped to improve long-range weather forecasts.

In the April edition of ‘Weather,’ the journal of the Royal Meteorological Society, an article co-written by Dr Peter Kettlewell will show how summer rainfall levels in the UK are affected by ‘remembered’ changes in winter air pressure over the North Atlantic ocean. The article is based upon the work of a team headed by Dr Kettlewell,

At only about 1,000 in the wild, China’s giant panda is among the most endangered species in the world. But there is still hope if we act fast. The panda’s greatest threat is habitat loss and new research identifies high-quality habitat that, if protected, could increase the species’ chances of long-term survival.

“The current network of nature reserves provides protection for less than half of the pandas’ remaining habitat and fails to conserve essential habitat for disp

While it is well-known that roads can spread invasive weeds, new research shows that some roads are worse than others. In Utah, areas along paved roads were far more likely to be invaded than those along 4-wheel-drive tracks. This suggests that limiting road improvements would help keep out invasive weeds.

“Each step of road improvement would appear to convert an increasing area of natural habitat to roadside habitat,” say Jonathan Gelbard, who did this work while at Duke University in Durh

Biologists believe that climate change is affecting living things worldwide, and the latest evidence suggests that warmer winters may mean fewer migratory birds. New research shows that as winter temperatures have risen in central Europe, the number of migratory birds has dropped. Ultimately, this may also decrease the number of migratory bird species there.

“We predict that with increasing winter temperatures…the number of long-distance migratory bird species should decline,” say Nicole L
