Astrophysicists Discover Primordial Clumps of Gas and Stars in the Milky Way

Just as archaeologists dig hoping to find traces of the past, an international group of astrophysicists managed to get into the thick cloud of dust around the centre of the Milky Way (also known as the bulge) discovering primordial clumps of gas and stars never found so far.

Discovery Paves Way for Real Analog Spintronic Devices

The observation of nonlinearity in electron spin-related processes in graphene makes it easier to transport, manipulate and detect spins, as well as spin-to-charge conversion. It also allows analogue operations such as amplitude modulation and spin amplification.

Hard-to-Track Lithium Identified and Measured in the Atmosphere of White Dwarfs

For the first time, hard-to-track lithium has been identified and measured in the atmosphere of burned out stars called white dwarfs, according to a study led by the University of North Carolina at Chapel Hill published online in the journal Science.

World's First Simulations of Space Plasma Show How Compressive Fluctuations Heat Ions

New simulations carried out in part on the ATERUI II supercomputer in Japan have found that the reason ions exist at higher temperatures than electrons in space plasma is because they are better able to absorb energy from compressive turbulent fluctuations in the plasma.

Combination of Astrophysical Measurements Provides New Estimates of Neutron Star Size

A combination of astrophysical measurements has allowed researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant that indicates the rate at which the universe is expanding.

New Research Measures Elusive Majorana Quantum States

A team of theoretical and experimental physicists have designed a new ultra-thin material that they have used to create elusive quantum states. Called one-dimensional Majorana zero energy modes, these quantum states could have a huge impact for quantum computing.

Researchers Use Quantum Simulation to Explore a "Bosonization" Phenomenon

In the text book of quantum mechanics, it was introduced that bosons and fermions, two types of elementary particles that build the universe, behave in a drastically different way. For example, bosons can share the same quantum state while fermions of the same kind cannot but fill available quantum states one by one.

Researchers Observe Dark Matter that Confirms Origin, Evolution of Universe

To date, over 50% of the matter in the universe has remained invisible to human beings. But astrophysicists had a notion where it might be located: In supposed filaments, incomprehensibly huge thread-like structures of hot gas surrounding and connecting galaxies and clusters of galaxies.

'Modified Gravity' Offers a Viable Explanation for Cosmological Dilemma

An international research team has recently published a study challenging that a rival concept to the well-known hypothesis of dark matter can more precisely estimate a galactic phenomenon that seems to defy the traditional rules of gravity.

Scientists Detect Radio Bursts Emanating from the Constellation Boötes

By monitoring the cosmos with a radio telescope array, a Cornell University-led international team of scientists has detected radio bursts emanating from the constellation Boötes. The signal could be the first radio emission collected from a planet beyond our solar system.
