Tiny Graphene Drums Show Potential to Act as Memory Chips in Quantum Computers

Graphene Drum Could Form Future Quantum Memory

A new study from Delft University reveals that tiny drums of graphene have the potential to act as memory chips in quantum computers. Scientists from TU Delft’s Kavli Institute of Nanoscience have demonstrated that they can detect extremely small changes in position and forces on very small drums of graphene. Graphene drums have great potential […]

Physicists Reveal a Neutron Halo Around Neutron-Rich Magnesium Nuclei

Physicists Reveal a Neutron Halo

Using the RIKEN Radioactive Isotope Beam Factory, physicists have revealed that the extra neutrons in a neutron-rich magnesium nucleus produce a neutron halo. Most stable atomic nuclei are made up of roughly an equal number of protons and neutrons. With the right equipment, however, physicists can create nuclei with many additional neutrons. These neutron-rich nuclei […]

Global Network of Radio Telescopes Settles Controversy Over Distance to Pleiades

Radio Telescopes Settle Controversy Over Distance to Pleiades

Using a global network of radio telescopes, astronomers have measured the distance to the Pleiades at 443 light-years – accurate to within one percent. Astronomers have used a worldwide network of radio telescopes to resolve a controversy over the distance to a famous star cluster — a controversy that posed a potential challenge to scientists’ […]

How the Immune System Combats Superinfection

How the Immune System Combats Superinfection

New research from Yale University shows how the immune system combats superinfections, revealing a biological basis for new vaccines against sexually transmitted diseases and possibly HIV. The immune system is great at making sure infections such as the herpes virus do not repeatedly infect a person, a condition known as a superinfection. Yet how the […]

Research Reveals Evolution Used Similar “Toolkits” to Shape Flies, Worms, and Humans

Evolution of Flies, Worms and Humans Share Patterns of Gene Expression

Several newly published studies reveal that flies, worms and humans share ancient patterns of gene expression. Although separated by hundreds of millions of years of evolution, flies, worms, and humans share ancient patterns of gene expression, according to a massive Yale-led analysis of genomic data. Two related studies led by scientists at Harvard and Stanford, […]

Seismic Analysis of Young Stars Reveals Their Evolution

Echography of Young Stars Reveals Their Evolution

A team of astronomers studying the surface vibrations in thirty-four young stars has found a clear relationship between seismic observables and evolutionary status, and in particular they are able to infer the internal stellar processes underway and the star’s corresponding evolutionary development. The evolution of a star depends crucially on its initial birth mass and […]

Spitzer Space Telescope Views Collision Between Large Asteroids

Spitzer Telescope Views Asteroid Smashup

Data from the Spitzer Space Telescope has revealed a huge amount of fresh dust around NGC 2547-ID8, leaving scientists to believe that two large asteroids crashed into each other, creating a huge cloud of grains the size of very fine sand, which are now slowly leaking away from the star. NASA’s Spitzer Space Telescope has […]

Neuroscientists Reverse Emotional Association of Specific Memories

Neuroscientists Reverse Emotional Association of Memories

Neuroscientists from MIT have identified the brain circuit that controls how memories become linked with positive or negative emotions, revealing that they could reverse the emotional association of specific memories by manipulating brain cells with optogenetics. Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach […]

Superabsorption Can Be Achieved and Sustained in Simple Nanostructures

Superabsorption of Light Via Quantum Engineering

Research from the University of Oxford establishes that superabsorption can be achieved and sustained in certain simple nanostructures, by trapping the system in a highly excited state while extracting energy into a non-radiative channel. The effect offers the prospect of a new class of quantum nanotechnology, capable of absorbing light many times faster than is […]

Proof That White Dwarfs Can Reignite and Explode as Supernovae

Astronomers Find Proof that Type Ia Supernova is Caused by a White Dwarf Star Reigniting and Exploding

New research shows without a doubt that white dwarf stars can reignite and explode as supernovae. Astronomers using ESA’s Integral gamma-ray observatory have demonstrated beyond doubt that dead stars known as white dwarfs can reignite and explode as supernovae. The finding came after the unique signature of gamma rays from the radioactive elements created in […]

Physicists Detect Neutrinos in the Sun’s Core

Physicists Detect Neutrinos Created by the Proton-Proton Fusion in the Sun

For the first time, an international team of physicists has directly detected neutrinos created by the proton-proton fusion process going on at the sun’s core. Amherst, Massachusetts – Using one of the most sensitive neutrino detectors on the planet, an international team of physicists including Andrea Pocar, Laura Cadonati and doctoral student Keith Otis at […]
