New Heavy Exotic Hadrons

Figure 1. Existing standard hadrons and exotic hadrons. At the B Factory experiment, a series of new exotic mesons containing charm quarks (c) have been discovered. Unlike these exotic mesons, the newly discovered Zb particles contain bottom quarks (b) and have an electric charge. If only one bottom quark and one anti-bottom quark ( b ) are contained, the resulting particle is electrically neutral. Thus, the Zb must also contain at least two more quarks (e.g., one up quark (u) and one anti-down quark ( d )). Credit: PhysOrg

(PhysOrg.com) -- Two unexpected new hadrons containing bottom quarks have been discovered by the Belle Experiment using the High Energy Accelerator Research Organization (KEK)'s B Factory (KEKB), a highly-luminous, electron-positron collider. These new particles have electric charge and are thought to be "exotic" hadrons -- non-standard hadrons, containing at least four quarks. Previously, a series of new and unexpected exotic hadrons containing charm and anti-charm quarks have been observed. This latest discovery from Belle demonstrates the existence of exotic hadrons containing at least four quarks in a particle system including bottom quarks .

New ampere and mass precise measure

2011-10-02T15:58:00.000-07:00

Redefining the kilogram and the ampere
New research using graphene presents the most precise measurements of the quantum Hall effect ever made, one of the key steps in the process to redefine two SI units.

"Key units to be redefined are the kilogram (mass) and the ampere (electric current). Presently the kilogram is defined by a physical lump of platinum-iridium and the ampere is defined via the force produced between two wires.
The goal is to define the kilogram in terms the Planck constant h and the ampere in terms of the electron charge e."

Faster than light

2011-09-22T15:53:00.001-07:00

Roll over Einstein: Pillar of physics challenged (Update)
A pillar of physics - that nothing can go faster than the speed of light - appears to be smashed by an oddball subatomic particle that has apparently made a giant end run around Albert Einstein's theories.

It seems that the muon neutrinos from CERN traveled 730 km and arrived the Gran Sasso Lab, Italy, a billionths of a second earlier than expected (it means it traveled that distance faster than the speed of light).

Carbon nanotube structures changed by 'attack' from within, researchers discover

(PhysOrg.com) -- A team of researchers involving scientists from The University of Nottingham has shown for the first time that chemical reactions at the nano-level which change the structure of carbon nanotubes can be sparked by an 'attack' from within.

Ultimate energy efficiency

2011-07-01T12:32:00.000-07:00

In magnetic contrast images (top) taken by the Advanced Light Source at Lawrence Berkeley National Laboratory, the bright spots are nanomagnets with their north ends pointing down (represented by red bar below) and the dark spots are north-up nanomagnets (blue). The six nanomagnets form a majority logic gate transistor, where the output on the right of the center bar is determined by the majority of three inputs on the top, left and bottom. Horizontal neighboring magnets tend to point in alternate directions, while vertical neighbors prefer to point in the same direction. Credit: Jeffrey Bokor lab, UC Berkeley

Magnetic memory and logic could achieve ultimate energy efficiency
Future computers may rely on magnetic microprocessors that consume the least amount of energy allowed by the laws of physics, according to an analysis by University of California, Berkeley, electrical engineers.

Magnetic Fields record

World record: The strongest magnetic fields created
On June 22, 2011, the Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 teslas. To reach this record, Sergei Zherlitsyn and his colleagues at the High Magnetic Field Laboratory Dresden (HLD) developed a coil weighing about 200 kilograms in which electric current create the giant magnetic field – for a period of a few milliseconds. The coil survived the experiment unscathed.

New Green Transportation

New electric diwheel hints at future of city transportation (PhysOrg.com) -- In a bit of technical wizardry, students from the University of Adelaide, Australia, have devised and built an electric diwheel, that with modification, could possibly solve inner city transportation problems. The team, comprised of 14 mechanical engineering students, has taken the idea of a diwheel and quite literally, turned it on its head, and in the process have created a vehicle that could be used to safely transport people around; all with a minimum amount of energy.

Applying Einstein's General Theory of Relativity to Superconducting Circuits

2011-06-13T07:41:00.000-07:00

ScienceDaily (June 11, 2011) — In recent years, UC Santa Barbara scientists showed that they could reproduce a basic superconductor using Einstein's general theory of relativity. Now, using the same theory, they have demonstrated that the Josephson junction could be reproduced. The results are explained in a recent issue of the journal Physical Review Letters.

Eurocopter X3: The world's fastest copter

(PhysOrg.com) -- If you asked a child how they would make a helicopter go faster, they would probably tell you to add another engine. The answer would be Zen simple and dead right. The engineers at Eurocopter also seem to have that same mentality and it worked.

"The X3’s speed milestone was reached on May 12 during stable, level flight – with the hybrid demonstrator maintaining a true airspeed of 232 kts. (430 km./hr.) for several minutes. This occurred during only the third mission after a scheduled upgrade that integrated the X3’s definitive gearboxes, enabling it to operate at full power." (font: eurocopter.com)

Tiny turbine in human artery harvests energy from blood flow

(PhysOrg.com) -- A small turbine located inside a millimeters-wide human artery could harvest enough energy from blood flow to power implanted medical devices, such as pacemakers and drug-delivery pumps. The concept has been presented by researchers at the University of Bern and the Bern University of Applied Sciences during the Microtechnologies in Medicine and Biology conference in Lucerne, Switzerland, earlier this month.
