 Researchers Observe Hydrogen-Bond Exchange May 08, 2008 | User rating: 4.7 / 5 after 46 vote(s)
| User comments: 7
Hydrogen bonds are quite small, on the level of a few angstroms. They can also be passed between two different molecules very quickly, at speeds of tens of times per second. But in spite of these properties, ... | |
 Large mammal species live harder, die out faster May 07, 2008 | User rating: 4.4 / 5 after 25 vote(s)
| User comments: 3
Throughout Earth’s history, species have come and gone, being replaced by new ones that are better able to cope with life’s challenges. But some species last longer than others, while others may die out sooner ... | |
Is quantum Internet search on the way? May 06, 2008 | User rating: 3.7 / 5 after 37 vote(s)
| User comments: 2
In classical computing, random access memory (RAM) is needed to make things “work.” But it is subject to a certain level of energy loss. But what if you could create low-energy quantum access memory (QRAM) that would not ... | |
 'Nanomechanical Oscillators' Could Lead to New Class of Computers May 02, 2008 | User rating: 4.2 / 5 after 67 vote(s)
| User comments: 12
More than 50 years ago, a graduate student in Japan conceived the “Parametron,” an electrical circuit that could form the basis for digital computers. The concept ultimately fell flat, but recently a pair ... | |
 Physicists Build a Quantum Gambling Machine April 30, 2008 | User rating: 3.9 / 5 after 32 vote(s)
| User comments: 3
Quantum gambling machines may not be popping up at futuristic casinos any time soon, but the devices could have other uses – such as enabling physicists to study game theory in situations where cheating is ... | |
 Can a Polymer Help Curb Arctic Ice Melting? April 29, 2008 | User rating: 3.3 / 5 after 39 vote(s)
| User comments: 14
In order to help prevent the melting of Arctic ice, a process that has been occurring at alarming rates in recent years, which many scientists believe is due gradual global warming, a group of researchers ... | |
 Goodbye, Bunny Ears: Future Antennas May be Flat April 24, 2008 | User rating: 4.2 / 5 after 75 vote(s)
| User comments: 11
The long, wiry antennas that protrude from airplanes, cars, cell phones – and even the bunny ears on some TVs – may one day become novelty items. Researchers are developing a smart-skin antenna that is simply ... | |
 Nanobacteria – Are They Alive? April 23, 2008 | User rating: 4.6 / 5 after 82 vote(s)
| User comments: 9
Tiny particles called nanobacteria have intrigued researchers in many ways since their discovery 20 years ago, but perhaps the most controversial question they pose is whether or not they are alive. | |
Distinguishing decoherence in quantum systems April 22, 2008 | User rating: 4.5 / 5 after 51 vote(s)
| User comments: 4
“Over the years, work on Bose-Einstein condensates, known as BEC, have led to more and more interesting phenomena,” Artur Widera tells PhysOrg.com. “This is because they behave according to quantum mechanics, and are ... | |
Measurement precision beats standard quantum limit April 21, 2008 | User rating: 4.6 / 5 after 60 vote(s)
| No comments yet
For physicists, measuring the precise magnitude of a physical quantity is a key to understanding quantum mechanics. However, there is a limit to how precise a measurement can be made, which is governed by quantum mechanical ... | |
Can three-photon absorption lead to better bio-imaging? April 18, 2008 | User rating: 4.2 / 5 after 29 vote(s)
| No comments yet
One of the more interesting concepts being looked at in terms of quantum chemistry is that of three-photon absorption (3PA). 3PA works when three photons are simultaneously absorbed in one event. Because three photon absorption ... | |
 The Ultimate Test of Atom and Neutron Neutrality April 17, 2008 | User rating: 4.6 / 5 after 45 vote(s)
| User comments: 3
Researchers from Stanford University have proposed a new way to test the neutrality of an atom and even a neutron, a method they say will be far more sensitive than current methods, able to probe the charge ... | |
