U of T physicists squeeze light to quantum limit
(08 Jan 2009)
A team of University of Toronto physicists have demonstrated a new technique to squeeze light to the fundamental quantum limit, a finding that has potential applications for high-precision measurement, next-generation atomic clocks, novel ......

UK scientists help museum curators to determine Viking trade routes by the metal in their swords
(07 Jan 2009)
Scientists at the National Physical Laboratory (NPL) in Teddington have worked with the Wallace Collection to analyse the contents of Viking swords – and the results shed new light on trade routes in the middle ages. Curators at the collection ......

Using light to move and trap DNA molecules
(06 Jan 2009)
A major goal of nanotechnology research is to create a "lab on a chip," in which a tiny biological sample would be carried through microscopic channels for processing. This could make possible portable, fast-acting detectors for disease ......

PICO and SALVE: Understanding the subatomic world better
(22 Dec 2008)
DFG-funded instrumentation enables world-class research in electron microscopy
Two new high-resolution transmission electron microscopes, co-financed by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), are set to open up new opportunities for research in physics and materials science. The new ......

'Seeing' the quantum world
(19 Dec 2008)
Computer animation used to help explain mysteries of quantum physics
Quantum physics is both mysterious and difficult to grasp. Barry Sanders, director of the University of Calgary's Institute for Quantum Information Science, is hoping to change that. Sanders, who is also the iCORE Chair of Quantum Information ......

New technique provides snapshot of all genes being transcribed across human genome
(18 Dec 2008)
Like Silly Putty lifting an imprint of the Sunday comics off a newspaper, complex enzymes called RNA polymerases lift information off DNA strands. The polymerases then transcribe those genetic instructions onto RNA for making proteins that ......

Biomarkers: What can they tell us
(16 Dec 2008)
As cancer researchers move away from the general use of chemotherapy and into more targeted approaches, scientists are working to discover effective ways to measure response and risk. Data presented at the CTRC-AACR San Antonio Breast Cancer ......

Molecules in the spotlight
(16 Dec 2008)
New technique allows real-time observation of molecules during chemical reactions
A novel x-ray technique allowing the observation of molecular motion on a time scale never reached before has been developed by a team of researchers from Ecole Polytechnique Fédérale de Lausanne (EPFL) and the Paul Scherrer Institute (PSI) in ......

MIT nanotubes sniff out cancer agents in living cells
(16 Dec 2008)
Chemical engineers use carbon nanotubes to monitor chemotherapy, detect toxins at the single-molecule level
MIT engineers have developed carbon nanotubes into sensors for cancer drugs and other DNA-damaging agents inside living cells. The sensors, made of carbon nanotubes wrapped in DNA, can detect chemotherapy drugs such as cisplatin as well as ......
