A team of FBI agents has been conducting interviews in recent weeks in the Dominican Republic and the United States, looking into allegations that Sen. Robert Menendez (D-N.J.) patronized prostitutes in the Caribbean nation, but has found no evidence to support the claim, according to two people familiar with the investigation.
Ghanaian top-flight side Berekum Chelsea have suspended their two coaches after the duo bizarrely traded punches in training in front of their players during on Thursday.
Dutch coach Hans Van Der Pluym openly fought his assistant Yusif Abubabar before their players as simmering rift between the two trainers embarrassingly got to a head.
The club has suspended the two coaches while junior team coach Annor Walker has been asked to take full charge of thew squad ahead of the weekend?s match.
Abubakar has been infuriated by the decision to bring back Pluym, the technical director of the club to take charge of the coaching duties.
Keen on establishing his authority Pluym clashed with Abubakar over who to take charge of the training which resulted in the punch-up.
?We confirm that the incident happened and we have asked the two men to step aside indefinitely until authorities decide to call them back,? Public Relations Officer Isaac Amponsah told Storm FM.
?It was a very unfortunate incident and we cannot support some of these serious issues to take over a club with such a huge respect.
?It will tarnish our image but we will take correctional measures to put the matter to rest once and for all.
?The authorities have tasked another assistant coach Annor Walker to take over for our subsequent training programmes as we continue to settle with the two,? Amponsah added.

Mice that can?t sense the two tastes find high sodium attractive

Salt has a split personality with its ability to enhance deliciousness or ruin a dish. Now scientists have revealed the underpinnings of salt?s dark side: Heavy doses of the seasoning trigger taste cells that detect bitter and sour flavors.
Mice without working versions of these taste cells find high levels of saltiness appetizing rather than repugnant, scientists report in the Feb. 14 Nature. The mice even liked a salt concentration equivalent to that of sea water.
The researchers don?t know how high salt levels kick-start the bitter and sour detectors, but the research suggests that a triumvirate of taste cells must oversee salt detection. Dedicated salt detectors enable attraction to salt, while bitter and sour detectors take over when salt levels skyrocket.
Feb. 13, 2013 ? Electric rocket engines known as Hall thrusters, which use a super high-velocity stream of ions to propel a spacecraft in space, have been used successfully onboard many missions for half a century. Erosion of the discharge channels walls, however, has limited their application to the inner solar system. A research team at Caltech's Jet Propulsion Laboratory, in Pasadena, Calif., has found a way to effectively control this erosion by shaping the engine's magnetic field in a way that shields the walls from ion bombardment.
Ions are produced in Hall thrusters when electrons from an electric current collide with the propellant atoms to form a plasma in the discharge chamber. Thrust is then generated by the interaction of this current with an applied magnetic field that creates a strong electric field. The magnetic field is mostly perpendicular to the channel walls whereas the electric field is mostly parallel to the walls. This electric field then acts as the driving force on the ions, accelerating them to very high speeds (>45,000 mph) toward the exhaust opening. However, the presence of a plasma in the thruster's discharge chamber leads also to a small component of the electric field parallel to the magnetic field lines. This component then accelerates some ions toward the discharge chamber (rather than the exhaust opening) causing erosion by sputtering material from the walls.
Guided by theory and numerical simulations, the research team designed a thruster configuration in which the effect of the plasma on the magnetic field lines along the walls is minimized, forcing the electric field to be perpendicular to the lines. Based on the numerical predictions, the effect of this magnetic field topology would be to accelerate ions away from walls while also significantly reducing their energy adjacent to the walls. Erosion then would be reduced without degrading propulsive performance. The method now known as magnetic shielding was verified by experiments in a vacuum facility using a modified thruster. The combined results of the simulations and experiments demonstrated that there was 100 to 1,000 times less wall erosion when using magnetic shielding.
The results were published in the American Institute of Physics (AIP) journal Applied Physics Letters.

Countering fake and substandard drugs: IOM report releases Feb. 13Public release date: 13-Feb-2013 [ | E-mail | Share ]
Contact: Christine Stencel news@nas.edu 202-334-2138 National Academy of Sciences
As the recent appearance of fake versions of cancer drugs illustrates, the increase in international production and trade of medications has come with an increase in illegitimate or poor-quality drugs reaching patients worldwide. Countering the Problem of Falsified and Substandard Drugs, a new report from the Institute of Medicine, recommends steps to improve the capacity of the United States and other nations to discover fake or subpar products and close gaps that allow products to be falsified or diluted.
The report will be released with a public briefing starting at 9:30 a.m. EST Wednesday, Feb. 13, in Room 120 of the National Academy of Sciences building, 2101 Constitution Ave., N.W., Washington, D.C. Seating is limited and advance registration is required. Those who cannot attend may watch a live webcast at http://www.iom.edu/fakedrugswebcast.

Advance copies of the report will be available to reporters only starting at noon EST Tuesday, Feb. 12. The report is embargoed and not for public release before 9:30 a.m. EST Feb. 13. To obtain an embargoed copy and arrange interviews with members of the authoring committee, contact the National Academies' Office of News and Public Information. More information on the study is available at http://www.iom.edu/Activities/Global/CounterfeitDrugs.aspx.
