New Earthlike planets in our cosmic neighborhood could be habitable

first_img Space,I’m shocked — shocked! — to learn that stores are turning Labor Day into an excuse to sell stuff. Wait — no, I’m not. As much as I respect the original intent of the holiday (which became official back in 1894), to most of us, it’s just a bonus day off — one that’s blissfully tacked onto a weekend. So, yeah, stores; go ahead, run your sales. I’m listening. Perhaps unsurprisingly, Labor Day doesn’t bring out bargains to compete with the likes of Black Friday (which will be here before you know it), but there are definitely some sales worth your time.For example:We’ve rounded up the best Labor Day mattress deals.We’ve also gathered the best Labor Day laptop deals at Best Buy.The 2019 Vizio P Series Quantum is back under $999.Be sure to check out Amazon’s roughly three dozen Labor Day deals on TVs and audio. Google Express is having a big sale as well, one that includes deals on game consoles, AirPods, iPhones, laptops and more.Below I’ve rounded up a handful of individual items I consider to be the cream of the crop, followed by a handy reference guide to other Labor Day sales. Keep in mind, of course, that products may sell out at any time, even if the sale itself is still running. Note that CNET may get a share of revenue from the sale of the products featured on this page.

Oooh, ahhh, indeed. At $250, the compact Rylo dual-lens camera is selling for its lowest price yet. And for an extra $50, you can get the bundle that includes the waterproof housing.This deal runs through Sept. 3; it usually costs $500.

Enter Tidal, the only “major” service that delivers lossless audio — meaning at least on par with CD quality, if not better. Want to see (er, hear) the difference for yourself? Grab this excellent extended trial while you can. It’s just $6 for three months, and it’s good for up to six listeners. Other Labor Day sales you should check out Best Buy: In addition to some pretty solid MacBook deals that have been running for about a week already, Best Buy is offering up to 40% off major appliances like washers, dryers and stoves.

I’ve used it many times and found it a great alternative to traditional car-rental services — in part because you get to choose exactly the vehicle you want (not just, say, “midsize”) and in part because you can often do pickup and dropoff right outside baggage claim.Between now and Sept. 1, the first 300 people to check out can get $30 off any Turo rental with promo code LDW30. An Echo Dot makes a fine match for any Fire edition TV, because you can use the latter to say things like, “Alexa, turn on the TV.” Right now, the 24-inch Insignia Fire TV Edition starts at just $100, while the 32-inch Toshiba Fire TV Editions is on sale for $130. Just add any Fire TV Edition to your cart, then add a third-gen Echo Dot, and presto: The latter is free.

I thought this might be a mistake, but, no, the weirdly named HP Laptop 15t Value is indeed quite the value at this price. Specs include an Intel Core i7 processor, 12GB of RAM, a 256GB solid-state drive and a 15.6-inch display.

University of Göttingen, Institute for Astrophysics As far as the universe goes, Teegarden’s star, a faint red-dwarf, is located pretty much next door. Astronomers have discovered two intriguing planets located in the star’s habitable zone where they could possibly host liquid water.A research team led by the University of Gottingen in Germany announced the Earth-like exoplanet discovery on Tuesday. Teegarden’s star sits just 12.5 light-years away from us, but it’s very different from our own sun. It’s much cooler and dimmer  and wasn’t even discovered until 2003.teegardensplanets2Enlarge ImageThis illustration imagines the view from the Teegarden’s star exoplanets back toward our solar system and Earth. University of Göttingen, Institute for Astrophysics “The two planets resemble the inner planets of our solar system,” said Mathias Zechmeister, lead author of a study on the exoplanets in the journal Astronomy & Astrophysics. They are both slightly heavier than Earth and might be part of a larger system with more planets.Before we get too excited, it’s important to remember that “Earth like” is no guarantee of a planet hosting life.  The discovery came about through the Carmenes project, which is focused on finding exoplanets around small, cool stars. Carmenes had already located nine other exoplanets.One fun feature of the planets around Teegarden’s star involves the star’s particular location. Possible alien occupants could conceivably look toward our solar system and spot Earth transiting the sun. This creates a faint dimming of our own star as our planet passes in front of it.Perhaps at the same time we’re looking toward Teegarden’s star, extraterrestrials are looking back at us, wondering if Earth could sustain life as they know it. In this wide, wonderful universe, it’s a possibility. Tags Though not technically a Labor Day sale, it’s happening during Labor Day sale season — and it’s too good not to share. Nationwide Distributors, via Google Express, has just about the best AirPods deal we’ve seen (when you apply promo code ZBEDWZ at checkout). This is for the second-gen AirPods with the wireless charging case. Can’t imagine these will last long at this price, so if you’re interested, act fast. The problem with most entry-level laptops: They come with mechanical hard drives. That makes for a mighty slow Windows experience. This Lenovo model features a 128GB solid-state drive, so it should be pretty quick to boot and load software, even with its basic processor. Plus, it has a DVD-burner! That’s not something you see in many modern laptops, especially at this price. Lenovo 130-15AST 15.6-inch laptop: $210 (save $90)last_img read more

Large scale qubit generation for quantum computing

first_img Pfister is a physics professor at the University of Virginia in Charlottesville. Working with Matthew Pysher, Yoshichika Miwa, Reihaneh Shahrokhshani, and Russell Bloomer, Pfister is using quadripartite cluster entanglement in order to make a breakthrough in the scalability for the number of qubits available for use in a quantum computer. The work is presented in Physical Review Letters: “Parallel Generation of Quadripartite Cluster Entanglement in the Optical Frequency Comb.”“There are several ways to make qubits with light,” Pfister explains. “One is to use a resonant mode of a cavity. A single laser cavity has millions of harmonic modes, and if you can design it, your scalability problem is solved.”The team at the University of Virginia made use of an optical frequency comb in their design to emit light fields that to be used as qubits. “We excite a great number of them. These are Qmodes, and can be used as qubits. I can control where I put them, and then also entangle them,” Pfister says. “We use a two-photon emission medium, putting one photon in a given frequency, and the other in another. The Qmodes are well separated in frequency.”Since the set up allows for entanglement, it is possible for Pfister and his colleagues to create a cluster entangled state designed especially for quantum computing. “Our design has correlations for all the qubits, and you can do measurements on them and implement quantum gates for one-way quantum computing,” Pfister says.Pfister points out that quantum computers of this sort cannot actually replace classical computers. However, quantum computers can be used for processing some types of information faster. “This is an attractive model for experiments that need cluster states. The big deal is that we got all these little quantum registers, and the entanglement is remarkably consistent.”The next step, Pfister says, is to entangle the already-entangled qubits into a bigger register. “It requires additional complexity to entangle them all together, and we’re on our way to this. We have shown that our control of entanglement is pretty good, but we need even better control to make entangled sets bigger than four.”Pfister thinks that the results of this experiment will result in increased interest in Qmodes of light. “People will start thinking differently about Qmodes of light,” he says. “We are driving the field, and hopefully we’ll make them on a single large scale, rather then make many small scale ones. Once that happens we will be ready to start with quantum processing.”“There are a lot of tools available right now to make qubits, and this is one of them,” Pfister continues. “Our experiment shows a great potential for scaling up the number of entangled qubits that can be used in quantum processing. We are another step closer.” More information: Matthew Pysher, Yoshichika Miwa, Reihaneh Shahrokshahi, Russell Bloomer, and Olivier Pfister, “Parallel Generation of Quadripartite Cluster Entanglement in the Optical Frequency Comb,” Physical Review Letters (2011). Available online: link.aps.org/doi/10.1103/PhysRevLett.107.030505 Measuring light and vacuum fluctuations from a time flow perspective (PhysOrg.com) — “Many people are trying to build a quantum computer,” Olivier Pfister tells PhysOrg.com. “One to the problems, though, is that you need hundreds of thousands of qubits. So far, scalability has been something of a problem, since generating that many qubits is difficult.” Explore furthercenter_img Copyright 2011 PhysOrg.com. All rights reserved.

Israel tourism numbers jumped 25 in 2017

first_img Posted by Share Thursday, January 4, 2018 Travelweek Tags: Israel Israel tourism numbers jumped 25% in 2017 JERUSALEM — Israel posted huge tourism numbers in 2017, with reports of a 25% increase and a record 3.6 million visitors bringing in US$5.8 billion of revenue.According to Israel’s Tourism Ministry, the increase of 700,000 tourists last year was a result of 18 new routes flying into Tel Aviv’s Ben-Gurion Airport as well as more flights to the Red Sea resort of Eilat, reports Reuters.The country saw additional airlift from Ryanair, Lot, WizzAir and WOW, as well as Air Canada and Transat. Hainan Airlines in particular is credited with boosting tourism from China by 46% with a new route.The United States, Russia, France, Germany and Great Britain were the top incoming markets in 2017. The top two tourist destinations were Jerusalem followed by Tel Aviv.Israel’s Tourism Ministry has been making big strides in infrastructure and tourism initiatives. Tourism Minister Yariv Levin has noted several initiatives are proving effective, including giving financial incentives to airlines to open new routes, collaborating with online travel agents, and working with entrepreneurs to build more hotels. << Previous PostNext Post >> About Latest Posts Travelweek Latest posts by Travelweek (see all) Another win for The Travel Agent Next Door: RCI Partner of the Year, Canada – March 28, 2019 You’re not imagining it, that waterfall really is coming out of a sksyscraper – July 26, 2018 Israel tourism numbers jumped 25% in 2017 – January 4, 2018last_img read more
