Hypothetical New Cosmological Model Known as Higgsogenesis

Recently in the news there's been talk of a new cosmological model known as Higgsogenesis. A paper outlining this model has been recently been published Physical Review Letters. The term Higgsogenesis refers to the first appearance of Higgs particles in the early universe, just as baryogenesis refers to the appearance of baryons (protons and neutrons) in the early moments after the big bang. While baryogene ...

Unstoppable Magnetoresistance

Mazhar Ali, a fifth-year graduate student in the laboratory of Bob Cava, the Russell Wellman Moore Professor of Chemistry at Princeton University, has spent his academic career discovering new superconductors, materials coveted for their ability to let electrons flow without resistance. While testing his latest candidate, the semimetal tungsten ditelluride (WTe2), he noticed a peculiar result. Ali applied a ...

How cloud Chambers Revealed Subatomic Particles

Atoms are made of electrons, protons and neutrons. Protons and neutrons are in turn made up of quarks. These are just some of the elementary particles that make up the foundation of modern particle physics. But how do we know about these particles when we can't see atoms directly, much less their constituents? One of the early methods was through a device known as a cloud chamber, and it is quite a clever i ...

Quick-Change Materials Break the Silicon Speed Limit for Computers

Faster, smaller, greener computers, capable of processing information up to 1,000 times faster than currently available models, could be made possible by replacing silicon with materials that can switch back and forth between different electrical states. The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with 'phase-change materials' (PCMs), which ...

Scientists Develop Pioneering New Spray-On Solar Cells

A team of scientists at the University of Sheffield are the first to fabricate perovskite solar cells using a spray-painting process – a discovery that could help cut the cost of solar electricity. Experts from the University's Department of Physics and Astronomy and Department of Chemical and Biological Engineering have previously used the spray-painting method to produce solar cells using organic semicond ...

Companion Planets can Increase Old Worlds’ Chance at Life

Having a companion in old age is good for people—and, it turns out, might extend the chance for life on certain Earth-sized planets in the cosmos as well. Planets cool as they age. Over time their molten cores solidify and inner heat-generating activity dwindles, becoming less able to keep the world habitable by regulating carbon dioxide to prevent runaway heating or cooling. But astronomers at the Universi ...

Google Eyes Chrome on Windows Laptop Battery Drain

chrome Google Chrome on Microsoft Windows has been said to have a problem for some time but this week comes news that Google will give it the attention others think the problem quite deserves. Namely, Google is to pay attention to a Chrome bug that saps the laptop batteries of Windows users. That bug has been around for years. Just because the browser is not being used at any time does not mean the browser ...

Physicists Propose Molecular Clock to Expose New Physics

A trio of researchers from Germany, Bulgaria and Russia has proposed the idea of using a molecular clock to determine if the electron-proton mass ratio changes over time. In their paper published in Physical Review Letters, Stephan Schiller, Dimitre Bakalov, and Vladimir Korobov describe a theoretical method for building such a clock and why if one were built, it might lead to new physics. Everyone knows th ...

Investigating the Detailed Structure of Large Biomolecules with a Non-Damaging X-Ray Technique

Biological molecules such as proteins can contain hundreds of thousands of atoms, which makes it very difficult to understand their function in detail. Identifying the exact atomic structure of these complex molecules is essential for biological studies and drug discovery, but the high-intensity x-ray beams needed to study them inevitably cause significant radiation damage to the molecules being investigate ...

85.9 Billion Bits Per Square Inch: IBM Research Sets New Record for Storing Massive Amounts of Big Data

Today, IBM researchers announced they have demonstrated a new record of 85.9 billion bits of data per square inch in areal data density on low-cost linear magnetic particulate tape—a significant update to one of the computer industry's most resilient, reliable and affordable data storage technologies for Big Data. At this areal density, a standard LTO size cartridge could store up to 154 trillion bytes (154 ...

Scientists Find Best Way to Rid a Garden of Snails

Gardeners wanting to rid their spring flowerbeds of pesky snails can ditch the beer traps and egg shells and instead develop a strong throwing arm. This is according to a new study in the journal Physica Scripta, which has used statistical models to show that removing snails out of the garden by a distance of over 20 metres or more is just as effective as simply killing them. According to the researchers, f ...

Oil Searchers Discover and Record Deep-Sea Graveyard off Angola Coast

A team of researchers looking for oil and gas deposits beneath the seafloor off the western coast of southern Africa has found four large "fish-falls" on the seabed: the carcasses of one whale shark and three mobulid rays. Finding vertebrate carcasses on the seafloor is quite rare, ocean scientists Nicholas Higgs, Andrew Gates and Daniel Jones report in their paper on the discovery published in PLoS ONE—the ...
