Scientists Reveal New Clues to Determining the Solar Cycle

Scientists Discover New Clues to Determining the Solar Cycle

Scientists have discovered a new marker to track the course of the solar cycle, providing a new way to watch the way the magnetic fields evolve and move through our closest star. Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun’s […]

Dot Against the Dark – New Image of Saturn’s Moon Mimas

New Image of Saturns Moon Mimas

This newly released image from the Cassini spacecraft shows Saturn’s moon Mimas. As if trying to get our attention, Mimas is positioned against the shadow of Saturn’s rings, bright on dark. As we near summer in Saturn’s northern hemisphere, the rings cast ever larger shadows on the planet. With a reflectivity of about 96 percent, […]

New Research Shows Extinctions During Human Era Worse Than Previously Thought

Study Shows Extinctions During Human Era Worse Than Thought

A new and more precise recalculation of the normal background extinction rate reveals that the rate of extinction in the human era is as much as 10 times worse than had been thought, finding that species die off as much as 1,000 times more frequently nowadays than they used to. Providence, Rhode Island (Brown University) […]

Scientists Uncover How Beautiful Color Patterns Develop in Zebrafish

Scientists Uncover How Beautiful Color Patterns Can Develop in Animals

Scientists at the Max Planck Institute have discovered how pigment cells arise and interact to form the ‘zebra’ pattern in zebrafish. The zebrafish, a small fresh water fish, owes its name to a striking pattern of blue stripes alternating with golden stripes. Three major pigment cell types, black cells, reflective silvery cells, and yellow cells […]

Hyades Supercomputer Reveals Why Sibling Stars Look Alike

Early Turbulent Mixing of Gas in Open Star Clusters Results in Unique Chemical Fingerprint

A newly published study details how astronomers from UC Santa Cruz used supercomputer simulations to trace the mixing of chemical elements in star-forming clouds, finding that stars formed from a single cloud bear the same unique chemical fingerprint. Early, fast, turbulent mixing of gas within giant molecular clouds—the birthplaces of stars — means all stars […]

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, […]
