New Algorithm Allows Astronomers to Track the Process of Star Formation in the Early Universe

New Computational Algorithm Can Follow Star Formation

Astronomers have developed a new computational algorithm that allows them to follow the star formation process down to the very small scales, tracking development of filamentary substructures and secondary clumps as wide as only a few tens of astronomical units. The first stars in the Universe are believed to have formed only a few hundred […]

Researchers Grow Large Graphene Crystals with Exceptional Electrical Properties

Researchers Grow Graphene Crystals with Exceptional Electrical Properties

By providing oxygen at the right surface concentration, researchers from the University of Texas at Austin were able to grow graphene crystals that were about 10,000 times as large as the largest crystals from only four years ago. Austin, Texas — When it comes to the growth of graphene — an ultrathin, ultrastrong, all-carbon material […]

Scientists Show That Atoms Can Work Collectively to Share Light

Scientists Show that Atoms Can Work Collectively

In a newly published study, scientists showed “photon-mediated interaction” between artificial atoms confined to a one-dimensional quantum system. An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light. Quantum physicists have long discussed such an effect, but it has not […]

Researchers Smash Room-Temperature Quantum Bit Storage Record

Researchers Smash Quantum State World Record

In a newly published study, an international team of researchers detail how they used an ensemble of phosphorous-31 donors in isotopically purified silicon-28 to demonstrate room temperature quantum bit storage lasting 39 minutes. A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key […]

New Data Reveals Two Galaxies Masquerading as One

New Data Reveals Two Galaxies Masquerading as One

New detailed radio data has revealed that what scientists thought was spiral galaxy UGC 10288 is actual two galaxies, one lying behind the other. What might look like a colossal jet shooting away from a galaxy turns out to be an illusion. New data from the National Science Foundation’s Karl G. Jansky Very Large Array […]

How Milky Way-Like Galaxies Have Evolved Over Time

How Milky Way Like Galaxies Have Evolved

A composite image from Hubble and Sloan Digital Sky Survey data reveals how Milky Way-like galaxies have evolved over time. This composite image shows examples of galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years. The galaxies are arranged according to time. Those on the […]

Scientists Stabilize the Magnetic Moment of Single Holmium Atoms

Researchers Stabilize the Magnetic Moment of Single Holmium Atoms

Researchers from Karlsruhe Institute of Technology have made a big step towards a single-atom bit, showing that the magnetic moments of single holmium atoms on a highly conductive metallic substrate can reach lifetimes of the order of minutes. One atom equals one bit: According to this design principle, we would like to construct magnetic data […]

Study Shows Root of Birth Defects Grounded in Early Embryonic Development

A Key Insight into the Biology of Embryonic Development

In a newly published study, Yale researchers detail a genetic mutation associated with congenital heart disease that disrupts a key signaling mechanism and leads to a form of heart defect associated with misalignment of major organs. The search for the cause of devastating birth defects has led Yale School of Medicine researchers to a key […]

New ScienceCast Video Explores the Mystery of Mars

MAVEN Orbiter Set to Explore Mars

As scientists ready for the launch of the MAVEN orbiter, a newly released ScienceCast video ponders the question, What Happened to Mars? Billions of years ago when the planets of our solar system were still young, Mars was a very different world. Liquid water flowed in long rivers that emptied into lakes and shallow seas. […]

Engineers Demonstrate Active Electromagnetic Cloaking

Researchers Develop an Active Invisibility Cloak

By surrounding an object with small antennas that collectively radiate an electromagnetic field, engineers demonstrate active electromagnetic cloaking. Invisibility cloaking is no longer the stuff of science fiction: two University of Toronto researchers have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects. Professor George Eleftheriades […]

Researchers Demonstrate a New Paradigm for Solar Cell Construction

A New Paradigm for Solar Cell Construction

Using perovskite crystals fabricated with a combination of potassium niobate and barium nickel niobate, a team of researchers has experimentally demonstrated a new paradigm for solar cell construction. For solar panels, wringing every drop of energy from as many photons as possible is imperative. This goal has sent chemistry, materials science and electronic engineering researchers […]

Evidence That Organic Material Can Survive the Impact of a Meteorite

Study Shows Organic Molecules Can Survive Meteorite Impact

In a newly published study, researchers from the Natural History Museum provide the first evidence that any organic material, either inside a meteorite or already on Earth, can survive the impact of a meteorite striking the planet at high speed. New research shows that organic molecules, on which life is based, can survive the impact […]

Oxford Researchers Creating Simpler, Cheaper Solar Cells

Perovskite Cells Improve Solar Efficiency

By working to improve perovskite cell efficiency, scientists at Oxford University are creating simpler and cheaper solar cells. Over the last four years, solar cells made from materials called perovskites have reached efficiencies that other technologies took decades to achieve, but until recently no-one quite knew why. Since perovskite was first used in 2009 to […]
