Dust Devils, Saturn’s Secrets And The Mystery Of An Ancient Eclipse

04.10.2005


The October issue of the Royal Astronomical Society’s journal, “Astronomy and Geophysics”, contains the following feature articles.



Ptolemy, Babylon and the Rotation of the Earth

Many authors have questioned Ptolemy’s account of a lunar eclipse that was supposedly observed by the Babylonians. John Steele finds that Ptolemy was right to believe that Babylonian observers saw the eclipse of 23 December 383 BC - which poses a problem that can be solved by invoking a large clock error or unusual atmospheric conditions.


Inside Dust Devils

Dust devils are rotating columns of dust-laden air that are common on both Earth and Mars. T J Ringrose presents a new way to produce convective vortices in the lab, comparing the results with dust devils on these planets.

Cassini at Titan: The Story So Far

The Cassini spacecraft’s first year examining Saturn and its moons has uncovered many surprises, not least the atmosphere and surface of the enigmatic moon Titan. Nick Teanby reviews the progress made and discusses prospects for the future.

Sounding The Dark Cosmos

Recent observations suggest that the universe has been accelerating rather than slowing down in the past few billion years. Bruce Bassett, Bob Nichol and Daniel J Eisenstein explain why the Wide Field Multi-Object Spectrograph, a proposed new instrument for the Gemini and Subaru telescopes, will need to look far into the universe, over a wide area, in order to map sound waves from the dawn of time and unravel the mystery of dark energy.

Promoting Planetary Science

Mike Hapgood summarizes the RAS’s position on planetary sciences in the UK, a subject that delivers world-class results, but needs focused support in order to continue to thrive.

(A summary of the RAS position was also issued in RAS press notice PN 05/39. The full statement is available on the RAS Web site.)

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...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

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...
