Quantum microscope for living biology
Quantum microscope for living biology
A team of Australian scientists has developed a powerful microscope using the laws of quantum mechanics to probe the inner workings of living cells. The team, a collaboration between The University of Queensland and the Australian National University, believe their microscope could lead to a better understanding of the basic components of life and eventually allow quantum mechanics to be probed at a macroscopic level.

Routes towards defect-free graphene
Routes towards defect-free graphene
A new way of growing graphene without the defects that weaken it and prevent electrons from flowing freely within it could open the way to large-scale manufacturing of graphene-based devices with applications in fields such as electronics, energy, and healthcare. A team led by Oxford University scientists has overcome a key problem of growing graphene - a one atom-thick layer of carbon - when using an established technique called chemical vapour deposition, that the tiny flakes of graphene form with random orientations, leaving defects or 'seams' between flakes that grow together.

Listening to electrons: new method brings scaling-up quantum devices one step closer
Listening to electrons: new method brings scaling-up quantum devices one step closer
Quantum devices will revolutionise computing, enabling huge calculations to be completed that classical computers simply cannot do. We're now one step closer to quantum computing becoming a reality thanks to research led by a team of University of Sydney physicists, who have found a new way to detect changes in charges smaller than one electron.

Gas promises bumper black hole 'weigh-in'
Gas promises bumper black hole 'weigh-in'
A new way of measuring the mass of supermassive black holes could revolutionise our understanding of how they form and help to shape galaxies. The technique, developed by a team including Oxford University scientists, can spot the telltale tracer of carbon monoxide within the cloud of gas (mostly hydrogen) circling a supermassive black hole at the centre of a distant galaxy.

3D microchip created
Each step on our spintronic staircase is only a few atoms high. I find it amazing that by using nanotechnology not only can we build structures with such precision in the lab but also using advanced laser instruments we can actually see the data climbing this nano-staircase step by step." —Professor Russell Cowburn, lead researcher of the study from the Cavendish Laboratory, the University of Cambridge's Department of Physics Scientists from the University of Cambridge have created, for the first time, a new type of microchip which allows information to travel in three dimensions.

How planets form: Astronomers weigh a protoplanetary disk with unprecedented accuracy
ANN ARBOR-In a study that gives astronomers new insights into how planets form, research led by the University of Michigan has enabled a dramatically more precise measurement of the amount of dust and gas in the planet-forming disk around a young star.

Reconcilable differences: Study uncovers the common ground of scientific opposites
Searching for common elements in seemingly incompatible scientific theories may lead to the discovery of new ones that revolutionize our understanding of the world. Such is the idea behind a mathematical framework Princeton University researchers developed that strips away the differences between scientific laws and theories to reveal how the ideas are compatible.

Mechanism Behind Wear at the Atomic Scale
Mechanism Behind Wear at the Atomic Scale
Wear is a fact of life. As surfaces rub against one another, they break down and lose their original shape. With less material to start with and functionality that often depends critically on shape and surface structure, wear affects nanoscale objects more strongly than it does their macroscale counterparts.

Beer's bitter compounds could help brew new medicines
Beer’s bitter compounds could help brew new medicines
Researchers employing a century-old observational technique have determined the precise configuration of humulones, substances derived from hops that give beer its distinctive flavor. That might not sound like a big deal to the average brewmaster, but the findings overturn results reported in scientific literature in the last 40 years and could lead to new pharmaceuticals to treat diabetes, some types of cancer and other maladies.

Secret of scent lies in molecular vibrations
Secret of scent lies in molecular vibrations
Molecular vibrations, rather than molecular shape, give substances their distinct smell according to a new study by UCL scientists. In a study designed to find out how smell is written into a molecule's structure, scientists tested whether changing how a molecule vibrates on a nano-scale changes its smell.

Chameleon pulsar baffles astronomers
Chameleon pulsar baffles astronomers
Using a satellite X-ray telescope combined with terrestrial radio telescopes the pulsar was found to flip on a roughly half-hour timescale between two extreme states; one dominated by X-ray pulses, the other by a highly-organised pattern of radio pulses. The research was led by Wim Hermsen from The Netherlands Institute for Space Research and the University of Amsterdam and will appear in the journal Science on the 25th January 2012.

Organic ferroelectric molecule shows promise for memory chips, sensors
Posted under: Engineering , News Releases , Research , Science , Technology , Uncategorized At the heart of computing are tiny crystals that transmit and store digital information's ones and zeroes. Today these are hard and brittle materials. But cheap, flexible, nontoxic organic molecules may play a role in the future of hardware.

UAlberta physics team cracks 100-year-old mystery
Thanks to the tenacity of star physics students and the new tools of nanotechnology, a University of Alberta physics team has cracked the code to a magnetic mystery that scientists have been trying to solve for nearly 100 years. U of A graduate students Jacob Burgess and Alastair Fraser made the breakthrough while working with Mark Freeman, a U of A physics professor and researcher at the National Institute for Nanotechnology , who led the new study.

Three-photon microscopy improves biological imaging
Three-photon microscopy improves biological imaging
Scientists may be a step closer to cracking one of the world's most compelling mysteries: the impossible complexity of the brain and its billions of neurons. Cornell researchers have demonstrated a new way of taking high-resolution, three-dimensional images of the brain's inner workings through a three-fold improvement in the depth limits of multiphoton microscopy, a fluorescence-based imaging technique with Cornell roots.

Penn Physicists Help Show Math Behind Growth of 'Coffee Rings'
Penn Physicists Help Show Math Behind Growth of 'Coffee Rings'
Last year, a team of University of Pennsylvania physicists showed how to undo the " coffee-ring effect ," a commonplace occurrence when drops of liquid with suspended particles dry, leaving a ring-shaped stain at the drop's edges. Now the team is exploring how those particles stack up as they reach the drop's edge, and they discovered that different particles make smoother or rougher deposition profiles at the drop edge depending on their shape.

Mathematical breakthrough sets out rules for more effective teleportation
Building a quantum computer is one of the great challenges of modern physics, and it is hoped that the new teleportation protocol will lead to advances in this area." —Sergii Strelchuk For the last ten years, theoretical physicists have shown that the intense connections generated between particles as established in the quantum law of 'entanglement' may hold the key to eventual teleportation of information.

Researchers confirm intrinsic superconductor behavior
When it comes to high-temperature superconductors, a class of materials called cuprates is king, and it is science's ongoing quest to determine their exact physical subtleties. Cornell physicists and materials scientists have now verified that cuprates respond differently when adding electrons versus removing them, resolving a central issue about the compounds' most fundamental properties.

Chemistry resolves toxic concerns about carbon nanotubes
Chemistry resolves toxic concerns about carbon nanotubes
Safety fears about carbon nanotubes, due to their structural similarity to asbestos, have been alleviated following research showing that reducing their length removes their toxic properties. In a new study, published today in the journal Angewandte Chemie, evidence is provided that the asbestos-like reactivity and pathogenicity reported for long, pristine nanotubes can be completely alleviated if their surface is modified and their effective length is reduced as a result of chemical treatment.
