Perseid meteor shower promises big show for stargazers

Posted by in category: space

ST. LOUIS (KTVI) — The Perseid meteor shower is now underway and is about one week from its mid-August peak.

Considered the best meteor shower of the year, you can see up to 50 meteors per hour, according to NASA, and sometimes even more if conditions are right. The fast and bright meteors often leave long wakes of light behind them as they streak through the atmosphere, making them easy to see even for the casual astronomer.

The Perseids get their name from the constellation Perseus because they appear to radiate from that spot in the sky, but the constellation isn’t the source. When comets come around the sun, they leave a dusty trail behind them. This time each year, Earth passes by debris from the comet Swift-Tuttle, which burns up in our atmosphere.

Eight trends accelerating the age of commercial-ready quantum computing

Posted by in categories: computing, quantum physics

1. Dark horses of QC emerge: 2020 will be the year of dark horses in the QC race. These new entrants will demonstrate dominant architectures with 100–200 individually controlled and maintained qubits, at 99.9% fidelities, with millisecond to seconds coherence times that represent 2x\u200a-3x improved qubit power, fidelity and coherence times. These dark horses, many venture-backed, will finally prove that resources and capital are not sole catalysts for a technological breakthrough in quantum computing.”,” protected”:false},” excerpt”:{“rendered”:”

Quantum computing will represent the most fundamental acceleration in computing power that we have ever encountered, leaving Moore’s law in the dust.

A Quintillion Calculations a Second: DOE Calculating the Benefits of Exascale and Quantum Computers

Posted by in categories: information science, quantum physics, supercomputing

A quintillion calculations a second. That’s one with 18 zeros after it. It’s the speed at which an exascale supercomputer will process information. The Department of Energy (DOE) is preparing for the first exascale computer to be deployed in 2021. Two more will follow soon after. Yet quantum computers may be able to complete more complex calculations even faster than these up-and-coming exascale computers. But these technologies complement each other much more than they compete.

It’s going to be a while before quantum computers are ready to tackle major scientific research questions. While quantum researchers and scientists in other areas are collaborating to design quantum computers to be as effective as possible once they’re ready, that’s still a long way off. Scientists are figuring out how to build qubits for quantum computers, the very foundation of the technology. They’re establishing the most fundamental quantum algorithms that they need to do simple calculations. The hardware and algorithms need to be far enough along for coders to develop operating systems and software to do scientific research. Currently, we’re at the same point in quantum computing that scientists in the 1950s were with computers that ran on vacuum tubes. Most of us regularly carry computers in our pockets now, but it took decades to get to this level of accessibility.

In contrast, exascale computers will be ready next year. When they launch, they’ll already be five times faster than our fastest computer – Summit, at Oak Ridge National Laboratory’s Leadership Computing Facility, a DOE Office of Science user facility. Right away, they’ll be able to tackle major challenges in modeling Earth systems, analyzing genes, tracking barriers to fusion, and more. These powerful machines will allow scientists to include more variables in their equations and improve models’ accuracy. As long as we can find new ways to improve conventional computers, we’ll do it.

A magnetic switch for the control of cell death signalling in in vitro and in vivo systems

Posted by in category: nanotechnology

Circa 2018 could be used on viruses too :3.


On application of a focused magnetic field, zinc-doped iron oxide nanoparticles with targeting antibodies attached are shown to activate cell death signalling in a spatially controlled manner. This triggering of apoptosis signalling, via the magnetically activated aggregation of receptors, is observed in both in vitro and in vivo systems.

Scientists rename human genes to stop Microsoft Excel from misreading them as dates

Posted by in category: futurism

Scientists have renamed 27 human genes to stop Microsoft Excel misreading them as dates. The changes have been underway for the past year but have been formally announced as new guidelines published by the HUGO Gene Nomenclature Committee. Scientist are overjoyed but annoyed Microsoft didn’t make the changes itself.

Intel investigating breach after 20GB of internal documents leak online

Posted by in category: security

US chipmaker Intel is investigating a security breach after earlier today 20 GB of internal documents, with some marked “confidential” or “restricted secret,” were uploaded online on file-sharing site MEGA.

The data was published by Till Kottmann, a Swiss software engineer, who said he received the files from an anonymous hacker who claimed to have breached Intel earlier this year.
