Science invention
Newly sensitive magnetic sensors allow for easier brain research
American physicists have developed a very handy device with enough sensitivity to record magnetic fields from electrical signals in the brain. With a small cell covered…
Science invention
Direct measurement of fluctuations in ferromagnetism
American and British physicists have for the first time measured these fluctuations in antiferromagnetic materials and surprisingly found them at low temperatures. This…
Science invention
Fermion pairs do not have superfluidity
In recent years, physicists have realized that fermions (such as electrons) can exhibit superfluidity because of their ability to pair at very low temperatures. Now, a g…
Science invention
Negative resistors are found in 2-dimensional electron gas
Any physicist who begins to study physics knows that resistance against a flow has a direction of charge, and the resistor is already a positive quantity. But Turkish an…
Science invention
Physicists confirm the existence of polariton condensation state
American physicists say they witness a unique combination of a Bose-Einstein condensate (Bose-Einstein condensate - BEC) in a system of pseudo-cooled particles called
Science invention
Negative refractive index in iron materials from natural metal in high frequency range
Physicists in Germany claim they have for the first time discovered a material with a natural negative refractive index, instead of the usual positive refractive index.…
Science invention
New method to convert heat into electricity.
Utal University physicists have developed devices that can convert sound into sound and then electricity. This technology offers promise for converting waste heat into e…
Science invention
The Casimir force exists in all liquids
Physicists in the US have come up with research results that the Casimir force - a mysterious quantum phenomenon that can absorb two copies when they are close enough -…
Science invention
Precise definition of temperature unit (Kelvin) thanks to laser spectroscopy techniques
French physicists have made a direct measurement of the Boltzmann constant by laser spectroscopy. This new technique involves observing the light absorption of ammonia (…
Science invention
Can nano-sized stripes be an important reason for superconductivity?
A team in Germany has discovered the existence of special structures in the form of nanometer-sized stripes (nanostripe) in a high-temperature superconducting compound m…
Science invention
Physicists set the 'speed limit' for superconducting magnetic fields in the future
A team of researchers led by Northwestern University physicists has identified a high-temperature superconductor - Bi-2212, a bismuth-containing compound that can be sui…
Science invention
French scientists successfully built the Einstein box
From 1927, Albert Einstein once thought of a box to trap light. At that time, his idea was still a proposed fictional experiment to test the relationship between mass an…
Science invention
Storage techniques and light recovery
American physicists are now able to record a synchronized pulse of light into a set of supercooled atoms - and afterwards
Science invention
The best equation of all time!
Readers of Physics World magazine voted the most popular equations of all time. But what are their meanings? The magazine's deputy editor, Dr. Matin Durrani, gave a simp…
