Right To Education..
The best example one can give "Fatima al-Fihri"

Many people are both misguided and confused regarding the treatment of women in Islam. They
believe the wrong media portrayal of Muslim women and they confuse Islam with male chauvinistic actions that are not supported by teachings in Islam or the example of our Prophet ( peace be upon him)......
The Prophet Muhammad (peace be upon him ) taught that the Muslim father who educates his daughters will go straight to heaven.

Levitation device moves objects with sound http://b4in.org/sEY9

Brazilian scientists have made advances in causing tiny particles to hover, or levitate, using sound waves. The development could have significant implications for improving safety when handling hazardous materials, as well as providing an opportunity for some mind-blowing kids/grown-up toys.

The acoustic levitation device from researchers at the University of São Paulo is featured on this week’s cover of the journal Applied Physics Letters, published by the American Institute of physics (AIP). By bouncing sound waves between two reflectors above and below a tiny polystyrene particle, the ultrasonic device demonstrates how objects can be controlled and held without the need for touching parts.

Similar gadgets have been built before, but the latest gives a degree of control and flexibility that has never been achieved. Previous devices required a precise setup where the sound source above and the concave reflector below were at fixed “resonant” distances.

The new one shows that a “non-resonant” levitation device is possible – one that does not require a fixed separation distance between the source and the reflector. By changing the orientation of the reflector, hovering particles can be moved around, and the next goal is to move objects larger than the polystyrene speck, which was 3mm across.

“Modern factories have hundreds of robots to move parts from one place to another,” said Marco Aurélio Brizzotti Andrade, who led the research. “Why not try to do the same without touching the parts to be transported?”

How does the impressive ultrasonic machine work? AIP tells us that: “In a typical setup, an upper cylinder will emit high-frequency sound waves that, when they hit the bottom, concave part of the device, are reflected back. The reflected waves interact with newly emitted waves, producing what are known as standing waves, which have minimum acoustic pressure points (or nodes), and if the acoustical pressure at these nodes is strong enough, it can counteract the force of gravity and allow an object to float.”

What Goes On Inside a Proton? That is the question, as the LHC gears up for another run. http://www.theguardian.com/science/life-and-physics/2015/feb/21/what-goes-on-inside-a-proton "Quarks and gluons make weird slopes and shapes inside the proton. Understanding them precisely was important for the first results from Cern’s Large Hadron Collider, and continues to be so as we approach the restart over the next few weeks."

'Single-photon emission enhancement' seen as step toward quantum technologies http://ow.ly/2TiGoQ
(Phys.org)—Researchers have demonstrated a new way to enhance the emission of single photons by using 'hyperbolic metamaterials,' a step toward creating devices in work aimed at developing quantum computers and communications technologies.

Engineers develop graphene-based biosensor that works in three ways at once http://ow.ly/2Tk7ss
(Phys.org)—One of nanotechnology's greatest promises is interacting with the biological world the way our own cells do, but current biosensors must be tailor-made to detect the presence of one type of protein, the identity of which must be known in advance.
