When a snowball melts, you can tell it has achieved a liquid state when the frigid water drips through your fingers. But if you could follow the melting process, driven by the heat of your hand, from its very first moments – the first trillionth of second, would you be able to point to the exact moment the snowflake crystals disorder into liquid H2O?

That’s the challenge facing researchers using the Sub-Picosecond Pulse Source (SPPS) to probe the activities of materials on ultrafast timescales. SPPS makes intense x-ray pulses lasting quadrillionths of a second (femtoseconds), enabling researchers to directly monitor the earliest atomic changes during melting with ultrafast x-ray diffraction.

Physicists at the University of Illinois at Urbana-Champaign have demonstrated for the first time the entanglement of two objects not merely in one aspect of their quantum natures, such as spin, but in a multitude of ways.

Entanglement is the quantum affinity between or among particles (such as atoms or photons) in which the measurement of some property for one particle automatically and instantaneously determines the corresponding property of the other particle.

Physicists in France have developed a new way form of "touch-screen" technology that relies on detecting the sound waves that are produced when a solid object is tapped by a finger (Appl. Phys. Lett. 87 204104). The technology could be used to make virtual keyboards and intelligent shop windows, and may also have applications in security and education.

When the surface of a solid object is tapped, sound waves reverberate through it. Different points on the surface produce slightly different sounds because the acoustic waves travel along different paths. Each point on the surface therefore has a unique acoustic "signature". Now, Ros Kiri Ing and Nicolas Quieffin of Sensitive Object, a new company based near Paris, together with Stefan Catheline and Mathias Fink of the University of Paris VII, have shown that this signature could be exploited in a new variation on traditional touch screens.

The speed of light waves in vacuum, 300,000 kilometers per second (186,000 miles per second), and denoted as c, remains the absolute speed limit for transferring matter, energy, and usable signals (information). However, a wave property known as group velocity can surpass c while still complying fully with the theory of special relativity, since it is not involved in transferring information, matter, or energy.

Traveling at the speed of light, a laser pulse could circle the earth several times in one second. In contrast, the sonic/ultrasonic "clicks" of a dolphin under the sea can only travel a single mile in that same second. The speed of ultrasound in water is about 1,500 m/s, some 200,000 times slower than the speed of light in a vacuum (known as c). The speeds of sound in most plastics are also some 5 orders of magnitude shy of c. So it may be hard to believe that by sprinkling in some small plastic beads, water can be made to support ultrasonic pulses with speeds faster than light. Not only can ultrasound pulses outrun light in this watery mixture, they can also propagate in negative time, apparently reaching a more distant point before a closer one. How is this possible? What does it mean? How does it fit within the known laws of physics? In the remainder of this article we will attempt to answer these questions.

There has been a recent tendency to apply Schroedingers wave equation to macroscopic domains, from Bose-Einstein condensates in neutron stars to planetary orbits. In these applications a hydrodynamical interpretation, involving vortices in some fluid medium is often given. The vortex picture appears surprising in light of more traditional interpretations of Schroedingers equation, and indeed often appears to rely on ad hoc analogies. The purpose of this letter is to examine the vortex hypothesis in light of a simple, transparent mathematical framework. We find that Schroedingers equation implies waves can be vortices also for a class of wave functions. Vortices occur in pairs that perform a sort of quantum computation by collapsing into either 0 or 1. Vortices collapsing to 0 (0-vortices) are longer-lived, and their ratio to 1-vortices is discussed.

The electric field breaks up the water molecules and the protons released in this process cause the rings to form. Using an optical microscope, the Swedish team observed that the vortex rings consist of water swirling around in very fine circles with diameters ranging from 10 to 50 microns (figure 1). Moreover, more than one vortex can form at higher voltages.

Physicists in France have demonstrated the Hall effect with phonons - vibrations of a crystal lattice - for the first time. The effect shows up as a temperature difference across a sample when a heat current is passed along the sample and a magnetic field is applied at right angles to both these directions (Phys. Rev. Lett. 95 155901).

The classic Hall effect occurs when an electric current flows through a conductor in a magnetic field. If the current and magnetic field are at right angles to each other, the Lorentz force deflects the electrons to one side and a Hall voltage builds up in the direction that is at right angles to both the current and the magnetic field. It has been assumed that the Hall effect could not exist for phonons because they are not charged.

Corrected [contrubuted by Prof. Dr. Fedor Mitschke]: Researchers at the University of Rostock in Germany have made the worlds first molecules of light pulses, which might allow a significant increase in the data transfer rate of fiber optical systems. The molecules are built of temporal solitons, pulses of light that do not dissipate or easily lose their shape like most other types of pulses. Solitons are useful for transmitting information because the signals can travel over long distances without degrading.

Solitons are waves that can have characteristics similar to material particles, like electrons and billiard balls. Although molecules made from spatial solitons have been demonstrated before, the researchers claim that this is the first time anyone has made temporal solitons stick together to form structures analogous to molecules.

Room Temperature Plasma

A good low-temperature plasma source must be able to work at room temperature and atmospheric pressure. Moreover, it should be hand-held and must not "arc" and heat up while operating. The new device developed by Laroussi and Lu consists of two electrodes, each made of a thin copper ring attached to the surface of a glass disk: the disk is about 2.5 centimetres across and has a small hole at its centre. These electrodes are then inserted into a dielectric tube and are separated by a gap that can be varied between 0.5 and 1 centimeter.

When helium gas is injected into the tube and short (less than one microsecond) high-voltage pulses are applied to the electrodes, a discharge is ignited in the gap between the electrodes. This produces a plasma plume that is ejected through the hole in the outer electrode. The plume can be up to 5 centimetres long, with the length depending on the flow rate of the helium and the size of the voltage pulses. The plume remains at room temperature and can be touched by bare hands.

Physicists at the University of Innsbruck have demonstrated that atom pairing (molecule formation) in Bose-Einstein condensates (BECs) using photoassociation is coherent. Coherent pairing of atoms (locking them into a particular quantum relationship) has been observed before using a tuned magnetic condition---a Feshbach resonance---between the atoms. But molecules made that way are only feebly attached. By contrast the process of photoassociation---i.e. using light to fuse two atoms into one molecule---allows more deeply bound molecule states to be established. The trouble is that the same laser light can also be absorbed to dissociate the molecules rather than only perform its associative task. The counter measure used by the Innsbruck researchers (contact Johannes Hecker Denschlag, 43-512-507-6340, johannes.denschlag@uibk.ac.at) is to create a "dark state" in which the light cannot be absorbed.

Mind and Machines

Gender matters as well. Men tend to get results that match their intent, although the degree of the effect is often small. Women tend to get a bigger effect, but not necessarily the one they intend. For example, they might intend to direct balls in the random cascade machine to fall to the left, but they fall to the right instead. Results are also greater if a male and female work together, but same-sex pairs produce no significant results.   Pairs of the opposite sex who are romantically involved produce the best results -- often seven times greater than when the same individuals are tested alone. Brenda Dunne, a developmental psychologist and the labs manager, said the results in such cases often reflect the two gender styles. The effects are bigger, in keeping with what the female alone would tend to produce, but more on target, in keeping with what the male alone would produce.

The development and verification of automotive Stirling engine (ASE) component and system technology is described as it evolved through two experimental engine designs: the Mod I and the Mod II.

Engine operation and performance and endurance test results for the Mod I are summarized. Mod II engine and component development progress is traced from the original design through hardware development, laboratory test, and vehicle installation. More than 21,000 hr. of testing were accomplished, including 4800 hr. with vehicles that were driven more than 59,000 miles. Mod II engine dynamometer tests demonstrated that the engine system configuration had accomplished its performance goals for power (60 kW) and efficiency (38.5%) to within a few percent. Tests with the Mod II engine installed in a delivery van demonstrated combined metro-highway fuel economy improvements consistent with engine performance goals and the potential for low emission levels. A modified version of the Mod II has been identified as a manufacturable design for an ASE.

It seems that placebos have a real physical, not imagined, effect – activating the production of chemicals in the brain that relieve pain, a new study suggests.

Placebos are treatments that use substances which have no active ingredient. But if people are told that what they are being given contains an active painkiller, for example, they often feel less pain – an effect that has normally been considered psychological.

Recent studies, though, suggest otherwise. For example, when a placebo was secretly mixed with a drug that blocks endorphins – the body’s natural painkillers – there was no placebo effect, showing that endorphins are involved in the placebo painkiller process (New Scientist print edition, 26 May 2001, p 34).

(2) Light propagates through empty space with a definite speed c independent of the speed of the source or observer.

(3) In the limit of low speeds the new formalism should agree with Newtonian gravity.

We shall see in later sections there is strong evidence that all three of these assumptions are in fact wrong. . . .

But why had all these discoveries [of absolute motion] not emerged at the beginning of the twentieth century when all the clues and theoretical insights had begun to emerge? The explanation is clear in the history books. In response to Michelsons bungled analysis and building upon the many theoretical insights by Fitzgerald, Lorentz, Larmor and others the Einsteins [Albert and his wife Mileva Maric-Einstein] usurped and formalised the work of all these physicists by asserting that absolute motion was without meaning and consequently not observable. The formalism introduced the geometrical spacetime construct which amounted to a truly bizarre reinterpretation of the relativistic effects that Fitzgerald, Lorentz and Larmor had introduced. Eventually the Einstein interpretation came to be accepted over the more physical interpretation that the effects on clocks and rods were real physical effects caused by absolute motion. Indeed in an even more bizarre turn of events it became accepted within physics, as a direct consequence of the Einstein postulates, that the relativistic effects were incompatible with absolute motion. Within a decade or so of the introduction of the Einstein re-interpretation absolute motion had become a banned concept in physics, and still is to this day. By the time Millers extraordinary interferometer experiments began to produce such dazzling evidence of absolute motion effects the prevailing belief in physics was that absolute motion was mutually exclusive to the various experimentally confirmed relativistic effects. So Miller had to be proved wrong.

Scientists at the University of Aberdeen have made a major breakthrough towards the mechanism of high-temperature superconductivity. Results from studies of a crystal structure of a new chemical compound containing copper and ruthenium have provided valuable insight into the mechanism of high-temperature superconductivity. The new results have shown for the first time that the mechanism of high-temperature superconductivity (when there is no resistance to the flow of electrical current) is actually coupled to the crystal lattice.

Physical theories and explanations of paranormal phenomena predate the more formal attempts to render the study of such phenomena a legitimate subject for science. The first formal attempt to study paranormal (psi) phenomena within a scientific framework came in the late nineteenth century as a response to the popular movement in modern spiritualism. After 1930, the remnants of this Spartan scientific movement developed into the science of parapsychology, largely through the experimental efforts of J.B. Rhine and his associates.

A physicist in the US has proposed a new way of quantifying the scientific output of individual scientists. Jorge Hirsch of the University of California at San Diego says that the "h-index" - which is derived from the number of times that papers by the scientist are cited - gives an estimate of the "importance, significance and broad impact of a scientists cumulative contributions." According to Hirsch the h-index "should provide a useful yardstick to compare different individuals" when recruiting new staff, deciding promotions and awarding grants (physics/0508025).

Study Shows Genetics Influences Choices in Friends, Mates

Aug. 10, 2005 — The reason our friends seem a bit kooky, and our mates may seem strange compared to ourselves, is that opposites attract. Right?

Nope. A large body of research suggests that we pick our friends, as well as our mates, because underneath it all they are very much like us.

How do you tell just how smart your robot is? Give it a universal IQ test, researchers suggest.

Traditional measures of human intelligence would often be inappropriate for systems that have senses, environments, and cognitive capacities very different from our own.

So Shane Legg and Marcus Hutter at the Swiss Institute for Artificial Intelligence in Manno-Lugano, have drafted an idea for an alternative test which will allow the intelligence of vision systems, robots, natural-language processing programs or trading agents to be compared and contrasted despite their broad and disparate functions.

ROSEMEAD, Calif.--(BUSINESS WIRE)--Aug. 9, 2005--Edison International (NYSE:EIX) subsidiary Southern California Edison (SCE), the nations leading purchaser of renewable energy, and Stirling Energy Systems today announced an agreement that could result in construction of a massive, 4,500-acre solar generating station in Southern California. When completed, the proposed power station would be the worlds largest solar facility, capable of producing more electricity than all other U.S. solar projects combined.

The 20-year power purchase agreement signed today, which is subject to California Public Utilities Commission approval, calls for development of a 500-megawatt (MW) solar project 70 miles northeast of Los Angeles using innovative Stirling dish technology. The agreement includes an option to expand the project to 850 MW. Initially, Stirling would build a one-MW test facility using 40 of the companys 37-foot-diameter dish assemblies. Subsequently, a 20,000-dish array would be constructed near Victorville, Calif., during a four-year period.

ESA -- Thanks to measurements by ESA’s Cluster mission, a team of European scientists have identified ‘micro’-vortices in Earth’s magnetosphere.

Such small-scale vortex turbulence, whose existence was predicted through mathematical models, has not been observed before in space. The results are not only relevant for space physics, but also for other applications like research on nuclear fusion.

Superlens breaks optical barrier

Physicists have built a lens that can image nano-scale objects using visible light

One of the best known properties of light is that it diffracts, bending or spreading around objects that lie in its path. A familiar example is when a collimated beam of light passes through a small aperture in an opaque barrier. If the aperture is large, the light emerges as a beam with the same radius as that of the aperture. But if the size of the aperture is similar to the wavelength of the incident light, the emerging light flares out from the aperture and forms a diffraction pattern whereby the intensity of the transmitted light has a broad central peak.
