Plants used to detect gas leaks, from outer space!

06.04.2006


Gas leaks can be potentially life threatening in the home, but the presence of gas stresses out plants too. Professor Mike Steven and colleagues from the University of Nottingham have found that changes in the physical properties of plants can act as an early warning of leaks in natural gas pipelines. “Our study was about testing the ability of satellite remote systems to monitor gas leaks via the spectrum of reflected light from plants, which changes when the plants are stressed”, says Steven. “A satellite image of the stress responses in vegetation should identify gas leaks at least as well as a visual report from a helicopter, which is the current method, and would be safer and possibly cheaper.” Steven will present his research on Thursday 6th April at the Society for Experimental Biology’s Annual Main Meeting in Canterbury [session P3]

In the UK in 2001, emission of methane from the gas distribution system was 16% of the total UK methane emissions; such losses are not only costly to the gas distributors, but can contribute to global warming since methane has a global warming potential about 8 times that of CO2. When plant roots are starved of oxygen the stress caused to the plant can be quantified from the spectral quality of light reflected from the leaves, even before the plant looks to be stressed. In the area surrounding a gas leak the escaping methane means the plant roots cannot get enough oxygen and so aerial parts of the plant appear stressed in satellite images detecting reflected light.

This remote-sensing technology can be used to detect any type of stress that causes asphyxiation of the plant roots. Steven and his colleagues are already considering other uses for the detection system. One such application may be to detect carbon dioxide leaking from underground stores used in proposed carbon capture and storage schemes. These stores are intended to help to prevent global warming: the argument is that if CO2 is sequestered indefinitely in underground reservoirs then it can’t be acting to absorb heat in the earth’s atmosphere. “Our own research attempts to address some of the issues related to public acceptability and safety: Will there be leaks? What environmental effects will any leaks have? Can we detect leaks?” says Steven.

Im Focus: New Method of Characterizing Graphene

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.

Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
