Microsoft Store 2018 Black Friday ad

While we saw a couple of Microsoft Surface deals courtesy of Best Buy’s Black Friday ad, Microsoft itself is offering more options to save with the Black Friday ad for its own store. On top of those, it has several specials on Windows laptops from its PC partners.

Microsoft has six different deals on its various Surface device, from the Surface Go to the Surface Laptop 2. The Go is the 10-inch tablet that most closely competes with the 9.7-inch iPad, and it will see $50 taken off the $399 price for its base model (Intel 4415Y processor, 4GB of RAM, 64GB storage). There’s also significant savings on the last-generation Surface Pro, which comes with a seventh-generation Intel Core m3 processor, 4GB of memory, 128GB SSD, and a Platinum Signature Type Cover for $599, $310 off the regular price. (Note, however, that you can obtain this deal right now from the Microsoft Store.)

That price reduction is no doubt related to the introduction of a refreshed Surface Pro 6, which is the Surface device discounted in Best Buy’s ad. The Microsoft Store adds three more deals on the new tablet, starting with the base version with Core i5, 8GB of RAM, 128GB SSD, and Type Cover for $799 ($260 off current price) and then taking $330 off the version with twice the solid-state storage, lowering the price to $999. That same $330 amount is also being slashed from a higher-end Surface Pro 6 stacked with Core i7, 16 gigs of RAM, and 512GB of solid-state storage, which brings the price to a still formidable $1,569. Finally, Microsoft is taking $300 off the new Surface Laptop 2, though it only vaguely says the discount applies to “select” configurations.

Microsoft is also happy to sell you some other manufacturers’ laptops that run its Windows 10 operating system. It has nine specials on Windows notebooks, in fact, from the likes of Dell and HP. At the low end, there’s an HP Stream configuration with Intel Celeron N4000 CPU, 4GB of RAM, 64GB of storage, and a 14-inch full HD display for $229 ($70 off current price), or a budget 2-in-1 in the form of an Asus VivoBook Flip with Intel Pentium Silver N5000 processor, 4GB of RAM, 64GB SSD, and 14-inch full HD touchscreen for $279 ($120 off). A final sub-$300 laptop deal is for an HP 15-DA0071MS with a last-generation Core i3 processor, 8 gigs of RAM, terabyte hard drive, and 15.6-inch touchscreen for $299 ($200 off).

If you want to step up to a Core i5 CPU, you’ll have a half-dozen choices, including the HP 15-DA0073MS for $349 and the HP Pavilion 15-cc610ms for $399, both of which are built around 15.6-inch touchscreen displays and pack 8GB of RAM, but the cheaper model comes with a last-generation Core i5 — albeit with a 2TB hard drive — while the pricier one has an eighth-generation Core i5, terabyte hard drive, and a full HD screen. There are also a pair of systems for $499: a Dell Inspiron 15 with Core i5, 8GB of RAM, 1TB hard drive, and 15.6-inch full HD touchscreen; and a Lenovo Flex 2-in-1 with Core i5, 8GB of memory, 128GB SSD, and 14-inch full HD touchscreen.

Rounding things out is another 2-in-1 in the HP Pavilion x360, which offers ismilar specs as the Lenovo but with a slightly larger 15.6-inch display and $599 price tag. If you’re looking for a gaming laptop on the cheap, Microsoft will be selling the Dell G3 with Core i5, 8GB of RAM, terabyte hard drive, 15.6-inch full HD display, and Nvidia GeForce GTX 1050 Ti graphics for $599.

Kids 5-11 appear safely protected by small doses of COVID vaccine, Pfizer says

Published

Small doses of Pfizer’s COVID-19 mRNA in children ages 5 to 11 appeared to produce strong antibody responses and comparable side effects to those seen in older age groups, according to the first top-line results from a Phase 2/3 clinical trial released by Pfizer and its partner BioNTech early Monday.

The trial data involved 2,268 children ages 5 to 11 years, and these children were given a series of two 10-microgram doses of the vaccine, 21 days apart. The dosage is just a third of the 30-microgram doses given to people ages 12 and above.

One month after their second dose, researchers measured the children’s levels of antibodies able to neutralize SARS-CoV-2 virus in a lab experiment. The geometric mean titer of antibody in the 5 to 11 year olds was 1,197.6 (95 percent confidence interval of 1,106.1 to 1,296.6), which is comparable to the geometric mean titer of 1,146.5 seen in people ages 16 to 25.

Pfizer described the vaccine as being well tolerated in children, with side effects generally comparable to what’s seen in people ages 16 to 25. But the company did not provide further data on the side effects.

It also did not provide any further data on vaccine efficacy, though experts expect that comparable neutralizing antibody levels will provide comparable levels of protection against infection, hospitalization, and death.

In an announcement this morning, Pfizer said it plans to submit the data to the US Food and Drug Administration, European Medicines Agency, and other regulators as soon as possible and “before the start of the winter season.” William Gruber, Pfizer’s senior vice president of vaccine clinical research and development, told Stat news that the company aims to submit the data for emergency use authorization to the FDA by the end of this month.

Once data is submitted to the FDA, it will take regulators several weeks to review the data and make a decision. That places the earliest estimates for vaccine authorization and availability for the 5-to-11 group at the end of October.

That timeline is largely in line with what Pfizer and US officials have said before. The company has also estimated that it will be ready to submit vaccine data for even younger children—ages 6 months to 5 years—about a month later, in the early November timeframe. If all goes well, that could put vaccine availability for that youngest group around the start of December.

“Since July, pediatric cases of COVID-19 have risen by about 240 percent in the US—underscoring the public health need for vaccination,” Pfizer CEO Albert Bourla said in a statement. “These trial results provide a strong foundation for seeking authorization of our vaccine for children 5 to 11 years old, and we plan to submit them to the FDA and other regulators with urgency.”

After Inspiration4, SpaceX sees high demand for free-flyer missions

Four amateur astronauts returned from a three-day private spaceflight this weekend overflowing with enthusiasm about the experience. “Best ride of my life,” said Dr. Sian Proctor, shortly after emerging from the Crew Dragon capsule.

Future customers for such a free-flying orbital experience, however, weren’t waiting for the initial reviews to express their interest in going to space. Even before the Crew Dragon spacecraft splashed down on Saturday night the Inspiration4 mission had already ignited a firestorm of interest.

“The amount of people who are approaching us through our sales and marketing portals has actually increased significantly,” said Benji Reed, Senior Director of Human Spaceflight Programs for SpaceX, during a call with reporters after the space tourism mission landed. “There’s tons of interest rolling in now.”

The company has declined to release pricing information for the Inspiration4 flight, which was purchased by billionaire Jared Isaacman. However, according to sources, the cost of an individual seat on future orbital flights is expected to be less than $40 million, and SpaceX will seek to drive prices down further for human orbital flights.

“If you look at the track record of SpaceX, we’ve driven down launch costs overall,” Reed said. “When you look at what it really costs for us to be servicing the NASA or other things that we’re doing, we’re trying very hard to drive that down. And in opening up the market to these kinds of visions, we’re doing something nobody’s ever been able to do before. But you’ve got to keep driving that cost down.”

SpaceX first flew humans on its Crew Dragon spacecraft in May 2020, with a demonstration launch for NASA carrying astronauts Doug Hurley and Bob Behnken to the International Space Station. Since then, the vehicle has launched two more operational crew missions for the space agency in addition to the first private mission.

Reed declined to speak about how many of the reusable vehicles SpaceX plans to build, but it currently has Endeavour, which is presently at the space station and has flown two flights; Resilience, also a veteran of two flights, which has been modified with a cupola for free-flying missions and does not got to a specific destination; and a third unnamed vehicle to be used for space station missions. With these three vehicles, SpaceX can likely accommodate at least six crew flights a year.

SpaceX could build more Crew Dragons for purely space tourism missions, Reed said. “If the demand is there, then we’ll want to to look at what we can do to continue to grow that,” he said. “And then, on the horizon of course, is Starship. Starship will be able to carry a lot more people at once. So, you know, there’s really both options and we have interest for both Dragons and Starships, which is pretty exciting.”

Demand for SpaceX's orbital tourism missions seems to be skyrocketing.

Starship remains under development, and it will launch to orbit on a Super Heavy rocket. It is not clear how soon the vehicle could be ready for human launches and landings—this seems at least a couple of years away, given the challenge of demonstrating propulsive landing coming back from orbit. However, a single Starship could easily carry dozens of people to orbit, instead of the four inside a Crew Dragon. NASA’s space shuttle holds the record for most people launched on a single spacecraft, with eight astronauts on the STS-61-A flight in 1985.

As it prepares for future customer missions, SpaceX will debrief the four amateur astronauts who flew on Crew Dragon to gauge their experiences over the three-day flight. Aside from a “minor” issue with a waste management fan, there appear to have been no technical glitches. SpaceX founder Elon Musk said he’s planning to add more amenities to future flights, such as a means to to heat up food, and wifi service from Starlink satellites already orbiting around the Earth.

Fire weather is getting worse in the American West

Published

on

California is famous for its beach weather, but it’s also growing increasingly infamous for its “fire weather,” which is when high temperatures, strong winds, and low humidity combine to prime the landscape to burn. It’s no accident that you’ve been hearing so much about wildfires in recent years: Thanks to climate change, fire weather is on the rise, a new analysis shows.

“It’s not just that it’s hot. It’s not just that it’s dry. It’s that all these conditions are happening at the same time,” says Kaitlyn Weber, a data analyst at Climate Central, a nonprofit news group that published the analysis. “There’s very clearly an increase in these fire weather days that’s been happening since the early 1970s across most of the western United States.”

Weber analyzed data from 225 weather stations from 17 western states going back to 1973, looking at temperature, humidity, and wind speeds, the three main variables that drive catastrophic fires. High temperatures and low humidity suck the moisture out of vegetation to create dry fuels, so one spark easily ignites a wildfire, which swift winds can then push across a landscape with incredible speed. The Camp Fire of 2018, for instance, moved so quickly that it overwhelmed the city of Paradise, killing 86 people, many in their cars trying to get out of town.

In the maps above, we can see the percentage change in annual days when these three variables exceeded the thresholds Weber used for her analysis. (Bluer colors mean fewer days, redder colors mean more days.) So with wind, for instance, that means speeds over 15 miles per hour, and for temperature it’s above 45 to 55 degrees Fahrenheit, depending on the season.

You’ll notice that the southwest, in particular, has gotten much hotter and drier—perhaps no surprise there. But at the same time, the region is seeing far more windy days, when an ignition is liable to turn into a speedy, intense blaze.

The map above visualizes when these three variables—temperature, humidity, and wind—combined to produce fire weather days, shown as percent change since 1973. All parts of Colorado have experienced at least 100 percent more fire weather days. Texas is looking gnarly, too, with the southern tip of the state seeing a 284 percent increase. And Central California is similarly troubled, with a 269 percent jump in fire weather days. “The Southwest was really coming out on top,” says Weber. “We’re even seeing some parts of Oklahoma and Kansas, some of these places where we don’t traditionally think of fires.”

But if you’re wondering why we don’t often hear about catastrophic fires in the plains states like we do in California, Oregon, and Colorado, that’s because “fire weather” just means the conditions are right for a blaze—it doesn’t mean they necessarily happen. “We’re not talking about the ignition of fires,” says Weber. “We’re talking about the number of days per year that the weather elements have primed the landscape for these high-risk fires that are really more dangerous to fight, and really more difficult to fight.”

Atmospheric conditions aren’t the only variables that exacerbate the likelihood of wildfires. Land management decisions in California and Oregon, for instance, play a role. These coastal regions are covered in forests that once regularly burned in a healthy way: Lightning would spark a relatively small fire that chewed through brush, clearing way for new growth but leaving many mature trees alive. Historically, Native Americans also set purposeful fires to strategically reset ecosystems. The landscape burned a lot, but that also meant it burned less intensely, since flammable brush didn’t have a chance to pile up between burns.

But in the past century or so, land managers have taken the opposite approach: fire suppression, or immediately putting out anything that might encroach on residential areas. That’s allowed the buildup of dry vegetation—more fuel. And with more human communities living in the “wildland-urban interface,” where the forest meets towns, people are also setting more accidental fires, whether from a cigarette butt thrown out a window or electrical infrastructure malfunctioning.

This is part of the reason fires are so much more catastrophic in California than in Kansas or Oklahoma: There’s just way more forest with way more accumulated fuel, and way more people living in harm’s way. To adapt, land managers in western states need to do more controlled burns, which will do the brush-clearing work that frequent, smaller wildfires used to do.

Climate change has also forced some seemingly contradictory seasonal changes. Because a warmer atmosphere holds more water, the amount of precipitation may actually increase in the future, while the length of the wet season is shrinking. In California, rains typically arrive in October and last until March. Now they are coming later in the year. “The dry season will expand into the normal wet season,” says climate scientist Ruby Leung, of the Pacific Northwest National Laboratory. “When we look at climate models projecting into the future, the fire season will become longer.”

Firefighters are already seeing this happen. California used to get its biggest blazes in the autumn, right before the seasonal rains arrived, when the landscape was extra parched from half a year without water. This coincided with ferocious seasonal winds that would drive huge wildfires. But now, because the rainy season is so short and the landscape has more of the year to dry out, fire season comes even earlier. “What we are seeing more consistently and more regularly is the fact that these fires are growing larger and larger, sooner than they typically would have in the past,” Issac Sanchez, battalion chief of communications for the California Department of Forestry and Fire Protection, told WIRED earlier this month. “So when August rolls around, late July rolls around, we’re seeing these dry conditions that are absolutely a result of climate change.”

Oregon, too, has had increasingly catastrophic wildfires of late, driven by the relentless increase in fire weather days. And Weber thinks things will only get worse until we slow global warming. “I think we can definitely expect fire weather days to increase as the climate continues to warm,” she says. “No matter what we do, there is no easy way out of this. We should just call it for what it is: There’s no substitute for reducing our emissions, and that’s really the name of the game.”
