A team of Williams College faculty and students is preparing to scientifically observe the total eclipse of the Sun that will sweep across the far side of Earth on March 29. Six undergraduates are joining Jay Pasachoff, Bryce Babcock, and Steven Souza of the astronomy and physics departments, who have worked together on a series of expeditions, most recently to study Pluto and its moon Charon.
The expedition is to Kastellorizo, a small island east of Rhodes in the Greek Dodecanese. Aside from Cyprus, it is the farthest eastern point of Europe, so many eclipse watchers are expected to travel there. The Williams group will be on site a week in advance to set up, test, and align its nearly ton of equipment. They are working closely with Professor John Seiradakis of the Aristotelian University of Thessaloniki, continuing a collaboration begun with joint observations there of the 2004 transit of Venus.
Pasachoff, chair of the International Astronomical Unions Working Group on Eclipses, will be observing his 42nd solar eclipse. He is Field Memorial Professor of Astronomy and director of the Hopkins Observatory at Williams. Babcock is coordinator of science facilities and staff physicist; Souza is instructor of astronomy and observatory supervisor. They last observed an eclipse in 2002 in Australia. The total solar eclipses since then have been visible only from Antarctica in 2003 and the mid-Pacific in 2005, preventing the use of complex equipment.

Airborne thermometer to measure Arctic temperatures

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
