The first phase of a working unit that can remove greenhouse gases from ordinary air is to be completed by the end of this year, according to a report in Chemistry & Industry magazine. Marina Murphy describes the groundbreaking work being done by brothers Allen and Burton Wright (and Burton’s engineering firm, Kelly Wright & Assoc, Tucson, AZ) to create a wind scrubber – a 10 square metre structure that will capture excess carbon dioxide (CO2) from the atmosphere around it.
Scientists have so far only discussed the theory of ‘wind scrubbing’ - this will be the first attempt to build a practical model. Unlike stack scrubbers, which address highly concentrated carbon dioxide streams, the Wrights will be looking at ways to process large volumes of air at low CO2 concentrations. Allen Wright describes the project as “feasible, and with some development, economically practical,” says Allen Wright. The design will be finished by the end of summer 2004, and the first phase of the prototype will be up and running by the end of the year.
Although some scientists agree that the project is a big step forward, others are less enthusiastic.

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'...
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....
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....
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...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
