  1. Surely this Amazon Prime Day you have bought something given the discounts that were offered and it is possible that on Black Friday we will bite again, or perhaps we are preparing for it. In any case, what we have to know is that according to the latest market analysis, the prices of NAND Flash memory chips are going to drop, which is going to involve the two main players: the price of RAM and the price of SSDs. The report comes to us from TrendForce statistics and trends agency, which are famous for their predictions for these types of markets. This report gives quite specific data, which will leave us, as we will see below, some fall percentages that really are to be taken into account. It has happened again, but this time it was much less predictable. After the outbreak of COVID-19 and its consequences, other factors have altered the market as we know it and it is nothing more than the arrival of higher capacity HDDs. This has led to price fluctuations and above all, it has modified the stock plans of the large NAND Flash companies. The forecasts were for a lower stock of units in the factories due to a higher level of sales, but all this has caused the opposite effect: there is a high level of stocks and excess capacity is also high, so there has been a imbalance between supply and demand. This also affects servers, where WD and Seagate with their new drives are catching up on the needs of their customers, which has caused the number of NAND Flash modules to increase on offer. Therefore, these factors will cause the market for SSDs (and presumably that of RAM, but for other reasons) to crash. How much drop can we expect and when will this SSD price drop occur? SSD vs HDD TrendForce estimates affirm that before the end of the year prices will fall by 10%, where already in 2021 prices will continue this decrease with 15% in the first quarter and possibly continue up to 20%. Therefore, if the estimates are true, this Christmas we will not have the SSDs at the lowest possible price, (historical minimum price offers aside), but well into next year. In any case, the greater demand for consoles will stop the blow, since the forecasts are for a very limited number of units as happened with the Ampere GPUs, so at some point next year prices will stop their decline and finally they will return to rise. When? Possibly by the middle of the year, but that is too long a time to be taken as a statement because the market changes every so often and the forecasts are adjusted to this. In any case, we do know that prices will fall for the remainder of the year and this is always good news for the final consumer.

  2. A few good weeks ago we were driving the new JMC Vigus Work, one of the many novelties that appeared in the quarantine period and that reaches a fairly competitive segment; the one of the trucks of a ton, but in the category of access, where we can see models like the JAC T6 or some of the old Wingle of Great Wall. And if we consider the tightness of the segment in terms of prices and offers, you really have to have differentiating attributes to stand out. Special design One of the most controversial points of the Vigus Work and that is inherited from the standard Vigus is the questioned design of its front. Honestly, it may be the "ugliest" release we've had this year. The design is subjective, but here there is no subjectivity that saves it: The trapezoidal-shaped main air intake is more prominent, though smaller than on the regular Vigus, making the slim upper grille that joins the spotlights look a bit more proportionate. The JMC logo does not look very integrated into the overall design of the truck and appears to have been installed later. The questionable large air intake that serves as the main grill, while giving the Vigus Work identity and recognition (you're not going to confuse it with any other truck), is the least attractive point. He earned nicknames of all kinds, from "Darth Vader" to "cod." On the street, he attracted attention. The good news is that it achieves an aerodynamic design, rare in a work truck. Compared to the standard Vigus, it has thinner tires (245/70 R16), gray handles and fog lights with a different design. Highlights are its accessories: it has tires, sills, similar "anti-roll" bars on the pick-up and hooks on the outside to tie down cargo. The wheel arches are very marked which helps it look imposing. The gate is a bit heavy. The pick-up, like all modern trucks, comes with a Line-X / Marson type synthetic liner that replaces the classic plastic bedliner. Dimensions in Vigus Work Length: 5.41 meters Width: 1.90 meters Height: 1.79 meters Between axles: 3.08 meters Clearance: 199mm Wading capacity: 450mm Load capacity: 845 kilos Pick-up length: 1.47 meters Pick-up height: 500 mm Angle of attack: 29 degrees Departure angle: 26 degrees Its dimensions are quite similar to that of its rivals. Perhaps it is not very high and its clearance is not the most generous among its rivals, but it has good access angles, the pick-up is quite high and due to its prominent front, it is positioned as one of the longest. Its 845kg load capacity also makes it one of the most load-bearing trucks, versus the JAC T6 or Dongfeng DF6. Inside Where we like the Vigus Work the most is inside, especially for its design, its assembly, its good soundproofing and its comfort. The first thing that stands out is that it has rubbery-touch (soft) polymers on the top of the console and doors, something very rare in the segment and that denotes a concern. The design, although not the latest generation, is still modern for a truck and the best: it is honest, that is, except for some aluminum-colored details, there are no pretentious materials. The ergonomics are fantastic: everything is close at hand and everything is very neat. The 7 "touchscreen multimedia system, although it does not have CarPlay or Android Auto, has an easy-to-use interface and somewhat mimics the look of Ford's Sync system. It was no, since JMC and Ford are partners. You're not going to find any buttons or knobs that look "generic Chinese": clunky knobs, buttons that look like "calugas", or indicators with generic numbers or fonts. Despite the fact that the upholstery is not perceived as very good quality and that the lower cushions are somewhat small, the seats are among the most comfortable that I have tried at the origin. They are soft and offer good lateral support, which helps comfort. The instrument panel is very legible, it has analog indicators for the tachometer, speedometer, tank and temperature, plus a small screen for the on-board computer. The floor is vinyl, ideal for work. There is no carpet or rubber flooring. It is easy to wash and sweep. Rear seats: This is a flat bench, with room for three people, however we recommend that it be only for two, because it has only two headrests and two three-point belts - it is not safe for the middle occupant. Offers good visibility and good head and knee room. Has handles to get on and a 12v outlet The backrest can be folded down, as can the bench, which can be folded up, offering more loading solutions. Ideal if you want to carry something in the rear seats that you cannot leave exposed in the pick-up.

  3. The Peruvian economy slowed its fall and registered a reduction of 9.82% last August due to the decreases in the mining, transportation and manufacturing sectors, the National Institute of Statistics and Information (INEI) reported on Thursday. According to the agency, the negative rate registered in the eighth of the month of the year was lower than that reached in the previous five months due to the launch of the third phase of the economic reactivation since July. In the January-August period, national production decreased by 15.66% and in the annualized period (September 2019-August 2020) it did so by 9.63%. In the case of the mining and hydrocarbons sector, this decreased by 11.18% due to the lower activity of the metallic mining subsector (-10.22%) due to the lower production volumes of gold, silver, lead and copper Manufacturing activity was 12.09% lower in August due to lower production in the consumer goods, intermediate goods, capital goods industry, and lower oil refining. The transport, storage and messaging sector fell 27.93% due to lower activity by air, rail and road. The accommodation and restaurants sector was the one that presented one of the greatest decreases with 60.95%, although the negative rate was lower in relation to the previous month. The categories tourist restaurants, coffee restaurants, restaurants, chicken shops, chifas and fast food were the most affected.

  8. The Google Pay application store for Android devices saw a record 28.3 billion downloads during the third quarter of this year, a figure 31 percent higher than the same period in 2019. The 28.3 billion downloads between July and September on Google Play are its highest figure so far in a single quarter, and are triple the downloads recorded by its rival, the Apple App Store, according to data collected by SafeBettingSites.com . In the case of the Apple store, downloads reached their all-time high in the first quarter of this year, with 9.3 billion. Between July and September, app download data fell to 8.2 billion. Regarding the number of applications, Google Play reached 2.7 million 'apps' in the second quarter of 2020 (5.85% more than in the previous period), while the App Store is the second in number of content, with 1.82 million applications for iOS (1.2% less than in the first quarter). Video games are the most popular category of applications, accounting for 13.49 percent of the total Google Play catalog in the second quarter, followed by education (9.11%), business (6.95%) ) and tools (5.98%)

  9. One of the most unknown parts due to the fact that marketing does not usually talk about them are the jump prediction units and the speculative execution of the processors. These drives are important because they are an essential part of performance in many processor architectures found in all types of computing devices. We explain quickly and easily what their role is and what advantages they provide. In this world nothing is certain, everything is pure uncertainty, even for a poor CPU that all it does is execute code sequentially until it unexpectedly gets a jump instruction. The CPUs when executing a program do it sequentially; This means that once they have read and executed an instruction, they go to the next line at the next memory address. The most common way to save code through recursion are jumps, instructions that change the value of the program counter that indicates the memory address of the RAM to be read by the CPU, causing the processor to execute the code located at starting from that new memory address that we have marked with the jump instruction. When a jump occurs, the time between the instruction executed prior to the jump and the first instruction after the jump is longer than moving from one instruction to another sequentially. What the jump prediction unit does is act as a forward and check if the jump is going to take place or not and go ahead. In the event that the jump is mandatory and does not have a conditional instruction in advance then the jump unit prepares the jump as quickly as possible and leaves the situation ready to perform it. With the conditional jumps the thing is different, because you cannot know if the jump is going to take place or not, since you have to execute the condition first. Prediction units cannot read the code, they only foresee the jump through certain conditions and there are times when they fail completely causing the CPU to lose a large number of cycles in previously jumping because the prediction unit has completely failed . Imagine that the jump prediction unit is a person who encounters the dilemma of the three doors or Motley Fool, does not know which to choose and is completely blocked because he needs to know in advance which of the three doors to take; This is where speculative execution comes in, allowing the CPU to choose the most suitable option. The idea of speculative execution is that all the possible options in a jump are executed in a separate execution branch, or in other words, that the CPU does not choose one of the three doors but all three at the same time and then once know which branch of code is running discard the two unused ones. This means that the CPU takes the jump as if it were already fulfilled beforehand, regardless of whether it is going to be fulfilled or not, and executes it internally. If the conditional jump occurs, then the CPU has gained an advantage over time and has advanced correctly, if it is not fulfilled then that branch of the code is completely discarded and in theory it does not affect the main branch. Therefore, speculative execution is the execution of code by the CPU that does not have to be necessary a priori, but with this there is a problem and that is that said code is valid for the CPU as long as it does not know the result of the condition that activates it and it will continue to be valid or cease to be valid as soon as the CPU knows if the condition is met or not.

  10. A contingent of the National Police went on Wednesday to the hotel where the Chilean referee Julio Bascuñán is staying, who directed the match between Peru and Brazil for the Qatar 2022 World Cup Qualifiers, to avoid attacks against him. The contingent made up of at least 10 agents seeks that the arbitrator can move, from Miraflores where his hotel is located, to the Jorge Chávez International Airport without problems to return to his country. The Peruvian team could not achieve their goal this Tuesday, October 13, after having lost 4-2 at the National Stadium against Brazil. Beyond the sporting issue, the referee Julio Bascuñán had an influential performance in the result by charging a questionable penalty to Neymar in the second half. Chilean media, such as Emol, La Tercera, among others, agreed that the performance of their compatriot was controversial because he did not review in the VAR in specific plays. Impact on Spain Likewise, the Spanish journalist Josep Pedrerol, host of the television program ‘El Chiringuito de Jugones’, shared the images and was surprised to see how dozens of police officers protect the referee for fear of reprisals. “Absolutely shielded by riot gear, shielded to protect the referee. Tempers are very hot after last night's game. The tension in Lima is maximum, ”Pedrerol said.

  11. Game Informations : Developer: Brett Todd Platforms PC Initial release date: June 6, 2014 at 5:04PM PDT Sometimes a title really an get the point across. Set-piece puzzler Kill the Bad Guy lays your motives bare with its blunt moniker, which nicely sums up your primary goal. The game has you murdering a rogues' gallery of ne'er-do-wells via assassinations that play out like gory outtakes from old cartoons, and lets you see the real aftermath of Elmer Fudd shooting Daffy Duck in the face. Yes, this is a game about killing, but it's a fun, lightweight game about killing that mostly succeeds by blending cunning logic- and physics-based puzzles with a great sense of humor relating to the daydream revenge fantasies that we all have about taking out everyone from serial killers to that guy in the Volvo who just cut you off. The single-player-only Kill the Bad Guy puts you in the employ of an international guild of assassins out to kill every villain who ever got off on a technicality, escaped the long arm of the law, set up a terrorist attack, parked in a handicapped spot, and so forth. You do so by rigging up various traps that allow the murders to look like accidents, presumably because any half-decent international guild of assassins wouldn't want its dirty work winding up on the cover of the New York Post. Everything takes place in real time, although you can pause the action or even speed it up to zip past dull spots when you're waiting for your victim to get into position for the kill. Each of the 60 levels (split into six chapters with 10 levels in each) included in the game is a small set-piece affair that involves no more than a couple of city blocks. The bad guy enters on one side of the map--which is sparsely populated by stores, vehicles, garbage trucks, pedestrians, and so forth--and walks around a set route until he exits a minute or so later. Everything is given a surreal, art-house style, with most of the backdrop presented in black and white. Only the bad guys really stand out, because they come equipped with colorful sporty jackets (think Starter in the '90s), faces painted with bull's-eye targets, and loads of bright red blood, which tends to end up smeared all over the landscape by the close of each level. Dark objects in levels can be manipulated with basic left and right clicks of the mouse, while light ones are just part of the scenery. How and when you manipulate these objects is where the puzzle part of the game comes into play. Victims don't just stroll straight to their deaths, so you need to adjust the landscape to both nudge them into the right spots and set up various kooky traps. You can indirectly guide bad guys by putting obstacles in their way. So whenever you want to discourage targets from going down a street, you throw a stop sign in their way, or the glass from a broken bottle, or even a dead dog. Or lure them where you want them to go with goodies like porno mags and, um, French bread. Black humor doesn't mesh well with real-life monsters like Albert Fish...although few people in human history are more worthy of being crushed into bloody goo by a piano. Black humor doesn't mesh well with real-life monsters like Albert Fish...although few people in human history are more worthy of being crushed into bloody goo by a piano. The trick is not being seen. At first, you just have to avoid the viewing cone of the victim (which can be toggled on and off), because he flees in panic if he spots anything suspicious (oddly enough, dropping a dead dog directly in front of somebody produces a pretty dramatic reaction). But later levels introduce patrolling cops, police cruisers, pedestrians, security cameras, and the like. Commit any sort of criminal act in front of them, and you instantly fail the mission. Kill the Bad Guy murders are always pulled off in elaborate ways reminiscent of Saturday-morning cartoons as reimagined by Edward Gorey. Falling pianos, explosive manhole covers, runaway cars, flaming pools of oil, and more all figure into the mayhem here. You might combine a rope with a crate and then hang the contraption on a building for the moment that your target walks past. Or rig up a wannabe catapult with some parking stanchions and a metal bar from a nearby construction site. Or spill some water and then cut a power cable right as a bad guy is getting his feet wet. This is a game about killing, but it's a fun, lightweight game about killing that mostly succeeds by blending cunning logic- and physics-based puzzles with a great sense of humor. Objects function in realistic, physics-based ways, but the game features sort of a "horseshoes and hand grenades" leeway where you can generally kill a baddie by getting reasonably close with a falling crate, an explosive, or a runaway lawn mower. You can never be foiled by any didn't-quite-get-me moments reminiscent of the grinning pigs in Angry Birds. Get close enough, and you can guarantee that you'll soon be seeing a screaming, flaming corpse-in-waiting running frantically around the map. Trapping and killing are imaginative and fun for the most part. There are a lot of chuckles to be had, as well as some devious plots to concoct. Levels offer a fair bit of replay value. There are almost always multiple ways to kill targets, as well as bonus goals like finding a victim's passport and grabbing the tooth that always pops out of a bad guy as he expires. Levels fly by, too, making this a very catchy game you can play on the fly when you have only a few minutes to spare. You can whip through even the toughest levels in little more than 10 minutes, and the average and easy ones can generally be solved in no more than a couple of minutes on your first attempt. But the developers don't push the design enough, and repetition is a problem. There are really just a handful of go-to ways to kill bad guys, so the thrill eventually evaporates from even wacky murders, such as slingshotting a dead dog onto somebody's head. Each of the game's six chapters also brings in a new gameplay element, like the aforementioned security cameras, and then the next few missions are fairly easy introductions to this added feature. As a result, the game isn't as challenging as it could be. The dark humor sometimes goes a little too far. Bad guys are given biographies in the splash screens before each assignment. Most are irreverent and goofy, but some reveal that you're taking on too-close-to-home villains like one of the Columbine killers, serial killer Albert Fish, and even Hitler. Profiling these real-life monsters with the game's blackly humorous text can be a little off-putting. Even though Kill the Bad Guy has its moments, it's never quite as challenging or as engaging as it could be. The biggest problem may be the platform. Such lightweight and casual play would likely work better on a phone or a tablet, especially at a cheaper price than the $14.99 sticker virtually attached to this Steam-distributed game. Still, even with these flaws, this is a diverting, innovative puzzler with more than enough charm to make staging loony-tunes murders look like an appealing pastime.

  22. Gambling in the cloud is an option that is having more and more presence in our daily lives. With services like Google's Stadia, Microsoft's XCloud, SONY's PlayStation Now and NVIDIA's GeForce Now fighting for their position in the market, it is interesting to know how these services work and what Cloud Gaming consists of. When we talk about gaming in the cloud, most people think of extremely powerful servers full of next-generation graphics cards that do all the rendering work for games, allowing users to enjoy great titles without the need for computers with great graphic power. But is it really so? We call Cloud Gaming or Game in the Cloud to the fact of playing a video game where the execution of the game is carried out in a remote system and therefore different from the one the user is using to interact and on which the information is presented at all times . Elements of Cloud Gaming Cloud Gaming therefore needs three different elements: Terminal: collects the player's actions and sends them to the server through the network for the latter to interpret them; It is also in charge of transmitting the image and sound information generated by the server to the terminal itself. Server: the remote system that, based on the actions carried out by the player, runs the game, generates the image and sends it over the network. Network: both the server and the terminal need a network with which to communicate, although we can have “Cloud Gaming” with respect to a local network and the operation is the same, it is understood that as a Game in the Cloud we are talking about a terminal connection -server over the Internet. The main reason for Cloud Gaming is that the user does not need extremely expensive hardware to play, so the improvement of the infrastructure falls especially on the part of the server that is controlled by the service provider, since the network it is a completely independent part of both the service provider and the customer. Stages of cloud play The game in the cloud works almost the same locally; It is a continuous loop that begins with the player performing an action and when she receives the image already generated on her screen that is a consequence of it. However, the game in the cloud adds a series of additional stages compared to playing with a console or a PC at home. These additional stages in Cloud Gaming, cause the server to need a greater graphic power to render the scene. Since you need it, to render in less time so that the encoding, reception by the terminal system and decoding can be carried out in just the right time. Encoding and Decoding The images rendered by the server are sent as an encoded video stream from the server to the terminal. The reason for doing this is because if the images were sent unencrypted we would need such a high bandwidth that we would not receive a single frame or very few per second. The trade-off is that using a video format to encode server-generated images causes image artifacts associated with these video formats. The servers use a special encoder in the form of an additional processor that allows this task to be performed at high speed in order to reduce latency. In terms of decoding, it is the only part of all the stages that is carried out in the local system and that requires a high processing capacity. Most of the decoders found in the devices are for mainstream video so they decode images too slowly causing additional latency, which makes them unsuitable for cloud gaming. As Cloud Gaming establishes itself in the market, we will see how different devices come with more advanced decoding systems.

  23. Game Informations : Developer: Seamus Mullins Platforms PC Initial release date: August 13, 2018 at 4:03PM Despite its focus on death and the afterlife, Flipping Death is a charming and wholesome adventure. Its zany and often eccentric characters bring the well-paced story to life with fantastic voice acting and a gorgeous 2D art style. Despite some frustrating platforming elements, its campy humor and satisfying puzzle mechanics make it a delightful journey throughout. Flipping Death puts you in the shoes of the recently departed Penny, a young girl who is accidentally thrown into the job of covering for Death. The role turns out to be rather elaborate, and you’re quickly tasked with helping ghosts resolve their unfinished business. In addition, you’ll have to help the wonderfully sassy Penny attempt to figure out how to return to the world of the living. In order to give these dead folk a hand and solve various puzzles, you’ll be frequently switching between the worlds of the dead and living by using your trusty scythe to possess mortals and take advantage of their special abilities. Some actions need to happen in one world before the other and vice versa, such as using a person's extraordinarily long tongue in the world of living to paint the boat of a deceased captain, or using a doctor's set of defibrillators to bring a recently passed ghost back to life. You'll need to constantly flip between the two worlds and experiment with character abilities in order to find the right solutions. Although a majority of solutions are distinct, the repetition of a few mechanics makes some puzzles predictable towards the end of the game. But at the same time, there are some that require a few too many flips in order to figure out the absurd logic behind the game’s ludicrous world. One such puzzle requires a young girl to fall down a chimney to be covered in ash, and in her new darkened state scare a fireman watching horror movies--literally to death--so he can then come to the afterlife and put out the fire on top of a ghost's head. There is a hint system which can help you when you hit a roadblock, but the clues aren’t very subtle and don’t leave much left for you to figure out. However, seeing these strange events play out is enjoyable for the spectacle alone. The possession mechanic means it’s easy to get sidetracked, testing each ability on other characters and the environment to see what odd results occur--which is convenient because that’s exactly what you’ll need to do to complete the wacky side challenges in each chapter and unlock Ghost Cards. These collectible cards give a pleasant layer of insight into the lives of the ghosts you’re trying to help and mortals you’ve been manipulating. And the interactions you have with each character, whether it be with the awkward police officer who lacks confidence or the local “superhero” whose power is to literally just poke people, are silly and humorous. It’s hard not to smile at all the bizarre situations they get themselves into. It helps that the voice acting is performed well, with every line delivered with a devotion and passion that makes sure there’s never a dull moment, as well as ensuring the humor lands. Some jokes can be overplayed, but for the most part, I was chuckling from beginning to end, and it was always a joy to meet a new set of characters. Penny herself seemingly embodies the voice of every person who has played a point-and-click adventure game, as she's constantly questioning and being bewildered by each character's thoughts and actions. Acting as a foil to the many antics happening around her, she provides much of the humor and is a rather refreshing protagonist. She keeps the story engaging through each chapter with her smart quips and unyieldingly sassy personality. The world of Flipping Death also feels lovingly crafted, filled with intricate details and diverse color palettes that bring each scene and character to life like a magnificent puppet show. The sprawling environments of Flatwood Peaks are occasionally reimagined to tell the story in interesting and unexpected ways, and a fast-travel system helps to make sure backtracking never feels like too much of a chore. A diverse instrumental soundtrack also accompanies your adventures, filling in the quieter moments but never intruding or distracting from conversations or puzzle solving. The one area where Flipping Death really falls flat is when you’re forced into annoying platforming sections in order to collect wandering souls and other odd currencies required to possess each character. These sections feel as if they exist solely to pad out the story and act as a break from puzzles, but the game’s controls aren’t accurate or satisfying enough for them to be any fun. Platforming quickly becomes an annoying gatekeeper that stops you from continuing to enjoy the rest of the game. Flipping Death's logic is sometimes too ridiculous for its own good, and frustrating platforming sections add some tarnish. But the game’s silly puzzles, self-aware humor, and crazy characters still make a wonderful experience filled with plenty of chuckles, which help to leave you satisfied as the credits roll.

  24. The coronavirus that causes COVID-19 can survive on surfaces like bank notes or phones for up to 28 days in cold temperatures and in the dark, according to a study by Australia's National Science Agency. Researchers from the CSIRO Center for Disease Prevention tested the longevity of SARS-CoV-2 in the dark under three types of temperatures. Survival rates decline when temperatures are hotter, the agency announced Monday. The scientists found that at a temperature of 20ºC, SARS-CoV-2 is "extremely resistant" on smooth surfaces such as mobile phone screens, surviving up to 28 days on glass, steel or plasticized banknotes. At 30º, survival falls to 7 days and 24 hours in temperatures of 40º. The virus survived shorter periods on porous surfaces like cotton "up to 14 days at low temperatures and less than 16 hours at high," according to the researchers. This is "significantly longer" than the results of previous studies that found that the virus can survive up to four days on smooth surfaces, according to the report published in the journal Virology Journal. Trevor Drew, director of the Australian Center for Disease Prevention, said the study was conducted with samples of the virus in different materials before subjecting them to an "ultrasensitive" method that found traces of live virus capable of infecting cultured cells. "This does not mean that the amount of virus could infect someone," he said on ABC public television. If a person is not "careful with these materials and touches them and then puts their hands in their mouth or touches their eyes or nose, they could become infected up to two weeks after (those objects) were contaminated," she warned. People "are much more infectious" Drew said there are some reservations. Among them, that the study was conducted with fixed levels of virus that could represent the peak of a typical infection, and there was no exposure to ultraviolet light, which can rapidly destroy the virus. The humidity was kept constant at 50% although the increase in humidity also harms the virus, the study says. According to CSIRO, the virus is spread primarily through the air but more research is needed to establish transmission of the virus through surfaces. "To develop risk mitigation strategies in high contact areas it is essential to determine the precise role of surface transmission, the degree of surface contact and the amount of virus it takes to become infected and how long (the virus) it remains viable, "says CSIRO's Debbie Eagles. But the main message is that "people are by far more infectious than surfaces," Drew told ABC.
