Gold nanoantenna peeps at proteins

Researchers in the US are using tip-enhanced near-field optical microscopy to resolve individual membrane proteins in liquid. The goal is to unravel the secrets of membrane organization and related processes such as nutrient transport and cell signalling.

Replacing Printed Silver with Copper

Silver has replaced copper in many applications that include UHF antennas in billions of RFID tags every year, membrane keyboards, battery testers on batteries and other printed electronics and electrics. This has happened because the copper, while having excellent electrical conductivity, had to be slowly electrodeposited and wastefully etched afterwards. In the past eight years, several organizations have declared that they can print copper.

Book Review of Molecular Modeling of Proteins. Methods in Molecular Biology, 443

This book covers many different aspects of protein modeling and is just one volume in an extremely large series (over 500 volumes published or planned). It contains 19 chapters, which are organized into six parts: (I) Methodology, (II) Free Energy Calculations, (III) Molecular Modeling of Membrane Proteins, (IV) Protein Structure Determination, (V) Conformational Change, and (VI) Applications to Drug Design. The main weakness of the book, as is frequently true for such edited volumes, is that the quality of the individual chapters is quite uneven. Some aspects of molecular modeling of proteins are quite well covered, whereas others are covered too briefly, with many important aspects being completely absent.

Hand-Held Cases House Industry-Standard Displays

Expanding the company’s Veronex hand-held case family is a component sized to accept industry-standard character and dot-matrix display modules. The maximum viewable width of these displays is 70 mm with an 82.5 mm PCB and the company’s hand-held case measures 150 mm x 90 mm x 30 mm. The top cover comes with a recessed area to accept a 70 mm x 137 mm membrane keypad. Two plastic end panels, held in place without fixings during assembly, provide I/O facilities at each end of the enclosure. Internal fixing pillars sit as far outboard as possible to give maximum width end panels so accommodate a large number of I/O connectors. Single-unit price is approximately $18.

No contractions

With my first son, I was had extreme water retention but it was a very happy pregnancy. He was due on August 20th, but my due date came and went. I received a letter from the Maternity Ward with an appointment for Sept 6th if there was no sign of the baby! I happened to mention this to my community midwife at a routine appointment and she was horrified. Before I knew it, I had an appointment for a membrane sweep. My sister was obsessed with my baby being born in September for the school cut off so at my appointment I expressed concern that the baby would be born at the very end of August so the midwife agreed to do the sweep the next day. Upon my return the sweep was done and the midwife was dubious of the results so I was booked in for induction on Sept 1st.
