Day One 3.0 Update Adds Audio Recording, Dark Mode, and New Editor Interface

Popular journaling app Day One reached version 3 today and introduced a number of new features for both free and premium users.

Headlining version 3 of the app is an all-new editor interface that the developers say has been built from the ground up. The action of editing an entry has been simplified so that now it’s just a matter of tapping wherever in the entry text that you want to place the cursor.

Tapping the “Aa” icon now brings up a new Editor menu with entry formatting options including Headers, Bold, Italic, Lists, Quote Block, Code Block, Rule Line, and indents. Meanwhile, Markdown support continues to include auto-conversion of Headers, Lists, Bold, and Italic into rich text.

In addition, Advanced Markdown like tables and HTML are also now supported by means of a Code Block option that auto-detects existing content wrapped in a code block and remembers your viewing preference (code/HTML rendered).

Elsewhere in the new UI, there’s a new entry content menu for for adding Photos, Camera, Audio, and Tags, a dynamic photo group collection grid, and entry checklists.

For Premium subscribers, Day One 3 brings a new Dark Mode that can be set to change with the local sunset/sunrise times. There’s also a new Audio Recording feature that supports transcription using Apple’s Speech dictation service and allows users to record 30 minutes of audio.

Day One 3 is a free download for iPhone and iPad from the App Store. [Direct Link] The Day One Premium subscription costs $34.99/year and is available via in-app purchase, while paid-app users of 2.0 get a lifetime discount for $24.99/year, also available via in-app purchase.

Walmart continues push against Amazon with Walmart eBooks store

It looks like Walmart is ramping up its efforts to take on Amazon. In partnership with Kobo, the company has announced a new ebook store called Walmart eBooks by Rakuten Kobo. The new service brings ebooks to Walmart customers both in-store and online, but perhaps more importantly it represents Walmart’s continued push against the likes of Amazon, which continues to bite chunks out of Walmart’s bottom line.

Thanks to the partnership with Kobo, Walmart eBooks will boast Kobo’s 6-million-title-strong library, as well as access to a $9.99-per-month audiobook subscription (which only gets users one audiobook per month), and more. Of course, customers will also be able to buy Kobo’s e-readers in Walmart stores or on Walmart.com, as well as purchase so-called digital book cards in any of 3,500 Walmart stores. Forty titles will be available at launch.

Thankfully, if you want to take advantage of the new service, you don’t have to buy a Kobo ebook reader — customers can also access ebooks through a Walmart eBooks and Kobo co-branded app, which will be available through both iOS and Android.

New customers will get a few perks, too. Those who sign up online will get $10 off their first ebook or audiobook through the service, and those interested in the audiobook subscription will also get a 30-day free trial.

It makes sense that Walmart would launch its ebook effort in conjunction with Kobo, rather than on its own. Kobo already has an established customer base, as well as its own series of e-readers. We’ve reviewed the Kobo Clara HD, one of the company’s flagship ebook readers, and scored it an impressive 4.5 stars out of 5. We also featured the Kobo Aura One as our top ebook reader to buy, thanks largely to its EPUB support and waterproof design. Walmart specifically will be selling the Kobo Aura, a lower-cost version of the Aura One.

In general, we’re likely to see more efforts like this from Walmart — though that doesn’t mean that it’ll help in the company’s push against online retailers. As Walmart mentions in its press release, the company has been building out its offerings through Walmart.com in general, including the launch of new categories like the ebook store.

POCO F1 review: Incredible performance at an unbeatable price

The POCO F1 is the most affordable Snapdragon 845 phone, and that isn’t likely to change ever.

poco-f1-review-1.jpg?itok=UoQ30MDC

Xiaomi has done a magnificent job carving out a name for itself in the smartphone segment. The manufacturer continues to be the largest handset maker in India, no mean feat considering the Indian market is one of the most competitive in the world.

A large part of Xiaomi’s success in India has to do with impressive numbers in the budget segment, where Xiaomi dominates. The Redmi and Redmi Note series make up a huge chunk of sales for the brand, and an unfortunate side effect of that budget-focused push is that Xiaomi is now perceived as a budget brand. Even a device like the Mi A2 — which retails for ₹16,999 ($250) in India — is a hard sell when a majority of Xiaomi’s phones sell for ₹10,000 ($150) or less.

That’s one of the main reasons why Xiaomi doesn’t launch its flagships in the country. The Mi Mix 2 was the exception to the rule, but the phone did little to sway customers looking to pick up a OnePlus 5T.

Xiaomi is once again making its foray into the mid-range segment, but this time it’s taking a different route. Instead of bringing the Mi 8 or the Mi Mix 2S to India, the Chinese manufacturer has created a sub-brand called POCO, which gives it the ability to start afresh in this category.

The POCO sub-brand is helmed by Xiaomi’s Lead Product Manager Jai Mani, who has been integral to Xiaomi’s growth in India over the years. Xiaomi is trying to attract a younger audience with POCO, and it’s clear from the marketing spiel that the focus will be on speed. Furthermore, the POCO brand will primarily cater to a global audience, and to that effect, the POCO F1 won’t be launching in China. The device — and subsequent phones that follow — will be unveiled in India and other global markets.

The brand isn’t trying to hide the fact that it’s a part of Xiaomi — the branding at the bottom of the phone says “POCO by Xiaomi”, and POCO will leverage Xiaomi’s existing after-sales network. Now that we have a better idea of what POCO is about, it’s time to take a look at the device itself.

POCO F1

poco-f1-review-15.jpg?itok=rr-Zy_mU

Price: ₹20,999 ($300)

Bottom line: The POCO F1 is the ideal upgrade for those using the Redmi Note 4 or Redmi Note 5. The performance on offer is right up there with the likes of the OnePlus 6, and the F1 is in a class of its own when it comes to battery life. But where it excels most is at delivering value — for ₹20,999 ($300), there really isn’t anything that comes close to the Poco F1.

Pros:

Unmatched value
Rugged design
Top-notch performance
Outstanding battery life

Cons:

Average camera
No water resistance

About this review

I (Harish Jonnalagadda) am writing this review after using the POCO F1 in New Delhi and Hyderabad, India for seven days. The phone was running MIUI 9.6 (9.6.11.0) based on Android 8.1 Oreo and hasn’t received any updates over the course of the review. The unit was provided to Android Central for review by Xiaomi.

poco-f1-review-10.jpg?itok=8nkW5DjI

POCO F1 Hardware

While the POCO F1 is using an identical panel as the Mi 8 series, it doesn’t share any design similarities at the back as the phone comes with a polycarbonate chassis instead of a glass finish. However, the F1 shares one key attribute that made Xiaomi phones stand out over the years: value for money. The POCO F1 will be sold in three variants, and all three options — including the one with 8GB of RAM and 256GB of storage — will be available for under ₹30,000.

The model with 6GB of RAM and 64GB of storage will retail for ₹20,999 ($300), the variant with 6GB of RAM and 128GB of storage will be available for ₹23,999 ($345), and the high-end option with 8GB of RAM and 256GB of storage will go on sale in the market for ₹28,999 ($415). Then there’s an Armored Edition with a kevlar back and 8GB/256GB for ₹29,999 ($430). Xiaomi is offering LPDDR4X RAM and UFS 2.1 flash memory as standard on all three variants.

POCO is taking aggressive pricing to a whole new level.

So if you’re looking to get your hands on the Snapdragon 845 on a budget, the POCO F1 is virtually unchallenged. ASUS’ ZenFone 5Z also offers similar hardware, but even that particular device costs ₹29,999 ($430). To put things into context, the OnePlus 6 starts off at ₹34,999 ($500), making it seem expensive by comparison.

Simply put, the POCO F1 is the most affordable phone to feature the Snapdragon 845, and that isn’t likely to change anytime soon.

Coming to the design side of things, the POCO F1 deviates from the mold with a polycarbonate back. We haven’t seen many polycarbonate designs in recent years — the budget segment has moved to metal, and the mid-range category is full of glass-backed phones. The POCO F1 doesn’t look premium by any stretch of the imagination, but what it lacks in looks it makes up for in durability.

POCO says a glass back increases manufacturing costs and reduces durability, so it went with a polycarbonate chassis that’s much more rugged in day-to-day usage. POCO also mentioned that a majority of customers using glass-backed phones opted to put a case on their devices anyway, and that a polycarbonate back negates that purchase. And should you need one, Poco bundles a clear case in the box.

Personally, I’ve had zero issues with POCO’s choice of materials. Sure, the device isn’t nearly as premium as the ZenFone 5Z or the OnePlus 6, but it should hold up to daily wear and tear much better. The phone will be available in four options — black, blue, red, and kevlar. The blue and red color options look interesting enough that it makes the F1 stand out, and the Armored Edition with kevlar is in a league of its own.

The kevlar option will be exclusive to the 8GB/256GB model, and the pattern will be immediately familiar if you’ve used OnePlus’ Carbon Fiber case. POCO is using DuPont’s Kevlar aramid fiber, and the material is wonderfully grippy and doesn’t attract smudges. The kevlar edition in particular feels great to hold and use daily, and although the back looks like a removable shell, it isn’t. There’s no way to switch out back covers, and the battery is non-removable as well.

As you’d imagine for a phone in this segment, the F1’s fit and finish are top-notch, and Poco hasn’t missed out on any essential features. The F1 comes with a 3.5mm jack that’s located at the top, a hybrid SIM card tray with the secondary SIM slot doubling up as a MicroSD slot, and USB-C charging. The power and volume buttons are located on the right, and they offer decent tactile feedback.

The POCO F1 has a sizeable notch at the top of the display, and the cutout holds the earpiece and an IR module that facilitates facial recognition. The speaker is one of the best you’ll find at this price point, and the F1 gets loud — playing games and watching videos is a delight on this phone. A major reason for that has to do with the fact that the phone has Dirac HD Sound — a mainstay on Xiaomi phones in the past. The earpiece also doubles up as a secondary speaker.

The POCO F1 features a 6.18-inch FHD+ 19:9 display with a resolution of 2248 x 1080. It also has a layer of Gorilla Glass 3 for protection against tumbles. Xiaomi has been making decent IPS LCD panels in this category for some time now, and the screen on the F1 is identical to that of the Mi 8SE. Colors seem muted out of the box, but you get the option to adjust the contrast levels. Switching to the increased contrast mode made colors much more vibrant, and I had zero issues with reading the contents on the screen under harsh sunlight.

Face unlock on the POCO F1 is incredibly fast.

Another noteworthy feature on the F1 is facial recognition. The phone has a dedicated IR sensor at the front that enables face unlock, and POCO is quoting a time of just 0.1ms. The feature itself is identical to the Mi 8, and with that phone unlikely to debut in global markets, it’s great that POCO is bringing the same facial recognition tech to its phone.

POCO said it considered getting rid of the fingerprint sensor because face unlock was so reliable, and this statement holds up in real-world use. The POCO F1’s face unlock feature is one of the fastest I’ve used to date, and it could just take the fight to the OnePlus 6 — and win — in this area. One particular area where it does better is low-light scenarios — the F1 fared much better at recognizing my facial features in the dark.

POCO’s main focus is on speed, so it’s no surprise that the F1 features the latest hardware available today. The phone is powered by the 10nm Snapdragon 845, and POCO is using the 2.80GHz bin. That’s the same chipset we’ve seen on the OnePlus 6 and ZenFone 5Z, and it delivers blistering performance day in, day out. MIIUI is well-optimized for the platform, and doesn’t feel bloated anymore.

The phone also has 6GB of RAM as standard, and comes with an 8GB option as well. To further differentiate the F1, POCO is incorporating liquid cooling in the device, which is designed to boost sustained peak performance times. There’s a vapor chamber next to the chipset that siphons heat and dissipates it over a wider area, preventing the phone from overheating during prolonged gaming sessions.

POCO is touting a decrease of up to five degrees Celsius because of liquid cooling, and playing PUBG on the device for over two hours didn’t produce an excessive amount of heat. I played a few rounds on the OnePlus 6 as well, and the back heated up considerably more. In that context, the F1 manages its thermals much better.

As for calls, the F1 had zero issues on Airtel and Jio’s 4G networks. POCO also worked with Qualcomm on enabling 4G+ on the device, allowing for faster throughput. Dual VoLTE is enabled out of the box as well.

Liquid cooling ensures the F1 doesn’t overheat during extended gaming sessions.

With the F1 primarily targeted to gamers, POCO slotted in a 4000mAh battery in the device. As we’ve seen on the Redmi Note 5 series, a 4000mAh battery and MIUI makes for outstanding battery life, and the F1 outmatches even the Redmi Note 5 in this category.

The Redmi Note 5 and Note 5 Pro are powered by 14nm Snapdragon chipsets, whereas the POCO F1 is running the 10nm Snapdragon 845. The node shift combined with the huge battery means you’ll easily get two days’ worth of use out of the F1. You’ll see anywhere between eight and nine hours of screen-on-time spread out over the course of two weeks, and even after heavy usage on a particularly hot day, I wasn’t able to get the battery to go below 30%.

The F1 supports Quick Charge 3.0, and Poco is bundling an 18W charger in the box. It takes just under two hours to charge the device fully, and you’ll be able to go from flat to a 50% charge in just under 30 minutes. Honestly, there isn’t a single flagship that comes close to the F1 in terms of battery life.

poco-f1-review-3.jpg?itok=bYQjKPYf

POCO F1 Software

On the software side of things, the POCO F1 is running MIUI 9.6 with a few extra additions. The notable one — and a feature that has been oft-requested by the Mi community — is the app drawer. The F1 comes with an app drawer that’s similar to what you’ll find on the Pixel 2, and POCO added a few customizations as well. You can access the full list of apps with a swipe up gesture, and there’s a shortcut to search apps along with a new sort feature that works surprisingly well.

The feature automatically sorts apps into various categories — Communication, Entertainment, Games, Tools, Lifestyle, and the like — and you have the ability to move the personalize the categories based on your usage. A swipe left gesture lets you go through the selected categories, and the feature comes in handy if you have a ton of apps installed. You’re essentially getting a similar functionality as folders, but the process is automatic.

That said, there’s no way to add an app to a particular category manually, and that poses its own set of problems. On my unit, games like PUBG and PinOut automatically showed up in the Games folder, but Alto’s Odyssey did not. Similarly, Slack showed up in the Finance & Business section and not the Communication category, so it’s clear that there’s still some work to be done in optimizing the sort function.

The POCO F1 runs MIUI, but you get a launcher and other extras.

There’s a secondary sort feature that lets you organize apps by color. You’ll see a list of colors at the bottom of the app drawer, and selecting one lists all the apps that prominently feature that hue. When I sorted using the green color, it pulled up the likes of Spotify, WhatsApp, Maps, Starbucks, Uber Eats, and so on. It’s definitely an interesting way to sort apps on the phone, but I didn’t get much usage out of it in the week I’ve used the phone.

Another nifty addition is the ability to install third-party icon packs directly from the launcher. There’s an option in the settings to do so, and this is also another feature that I was particularly looking for in MIUI for some time.

Aside from that, it’s the same MIUI experience as on any other Xiaomi phone. There’s enough customization on offer to satiate even the most die-hard fan, and the interface itself doesn’t feel bloated anymore. Far from it. If anything, the phone feels as fluid as the OnePlus 6 in the week I’ve used it.

On the downside, it comes with a ton of bloatware: you get everything from the usual UC Browser, Amazon, and Facebook, to Microsoft apps like Word and Excel, and plenty more. The good news is that all of these apps can be uninstalled.

Oreo for now, but Android 9.0 Pie is coming in under three months.

And because the MIUI experience is never entirely complete without some sort of issue with notifications, the POCO F1 has its share of bugs. This time around, the issue primarily revolved around Newton Mail and Slack — notifications for either app just didn’t show up, and I had to manually toggle Autostart for both to receive notifications. I had the same issue in MIUI 9 with Gmail, and to its credit Xiaomi has fixed that particular problem in a subsequent update. That’ll likely be the case here as well.

The current MIUI 9.6 stable build (9.6.11.0) is based on Android 8.1 Oreo and has the June 01, 2018 security patch. POCO has mentioned that it will roll out the Android 9.0 Pie update in under three months, with a beta build ready for enterprising users shortly.

The Pie-based build will feature MIUI 10, which has a new notification pane that offers similar functionality to that of the Pixels. The pane in the current MIUI 9.6 build also has a similar white-and-blue aesthetic, and POCO says it will refine the feature-set in the coming months.

And as is the case with all phones running Android 8.1 Oreo out of the box, the POCO F1 offers Treble, and POCO says it will honor the warranty for those users that tinker with custom ROMs. Kernel files for the F1 will be released before the end of the month, and POCO is actively encouraging the modding community to build custom ROMs for the phone.

POCO F1 Camera

It should be clear by now that POCO shares a lot of the internal hardware with the likes of the Mi Mix 2S and the Mi 8 series. That continues with the camera as well, with the device featuring a 12MP IMX363 sensor from the Mi Mix 2S and a 5MP secondary shooter. There’s EIS to stabilize videos, and a front 20MP f/2.0 camera with portrait mode and pixel binning.

poco-f1-camera-6.jpg?itok=poo92CEW

poco-f1-camera-5.jpg?itok=wT-FK5gC poco-f1-camera-4.jpg?itok=tHDcd9FT

POCO is leveraging Xiaomi’s AI scene detection feature, with the AI able to detect over 25 scenes and 1000 scenarios and automatically adjust the shooting mode. The feature isn’t as aggressive as that on Huawei/Honor devices, but it does make a difference in a few scenarios.

The camera itself is decent for what the phone costs. Most photos taken in daylight come out with plenty of detail and high dynamic range, but there are a few instances where the images look oversaturated. And while the phone takes decent shots in low-light conditions, it misses out on a lot of details in the background.

poco-f1-review-2.jpg?itok=8pqYTSTc

Should you buy it? Absolutely

With the F1, POCO isn’t going after the likes of OnePlus 6 or even the ASUS ZenFone 5Z. The price point is more in line with that of the Nokia 7 Plus, and the company is targeting current Redmi Note 5 Pro or Redmi Note 4 users looking for an upgrade.

Considering both devices have sold millions of units over the last two years, there’s no shortage of potential customers. POCO is in a win-win situation here: it’s starting off with a clean slate that’s free from any connotations around brand perception, and at the same time it is able to tap into Xiaomi’s supply chain.

The phone itself is superb, offering unmatched value for money in this category. The design won’t win any awards, but it is great to use on a day-to-day basis. Battery life is outstanding, as is the performance. MIUI feels much more polished than before, and the introduction of a launcher has eliminated a major point point for customers.

It comes down to how the camera holds up against the likes of the OnePlus 6 and other devices in this segment, but ultimately, you’re getting more than your money’s worth with the POCO F1.

As for when you’ll actually be able to get your hands on one, POCO is set to kick off sales from August 29. The phone will be available in weekly flash sales, but POCO says it will ramp up manufacturing to meet initial demand as the weeks go by.

As for other markets, POCO says it will bring the F1 to over 50 markets in the coming weeks and months.

4.5
out of 5

The POCO F1 once again demonstrates just how cognizant Xiaomi is of the Indian market. By launching a Snapdragon 845-powered device at this price point, Xiaomi is able to effectively shift the conversation away from whether the Poco F1 can hold up to the OnePlus 6 and the ZenFone 5Z.

It’s another matter entirely that it manages to do so, but the fact that it costs just ₹20,999 ($300) makes it one of the best options in the market if performance is what you’re after.

Watch DOTA 2 pros fight for millions at The International 8

Watch live video from dota2ti_newcomer on http://www.twitch.tv
Oh, how games have changed. In 1989, a film called The Wizard depicted kids competing in a video game tournament for a $50,000 grand prize. The film was panned at the time for being ludicrous, essentially an extended commercial for Nintendo games. This August 20-25, competitors from around the world will take the stage at Rogers Arena in Vancouver to compete in an actual video game tournament with stakes far grander than any ’80s film could have ever predicted. The winners will leave the arena as millionaires, if they weren’t already.

The game is Dota 2, and the tournament is known as The International, a name that conveys the sort of respectability to which esports aspire. This year will mark the eighth International. Hosted by Dota 2’s developer, Valve, The International has grown in stature at a remarkable rate since its inception. The first International was held in a hall at Gamescom with a grand prize of $1 million, but this year, the eighth installment of the spectacle will fill Vancouver’s Rogers Arena — instead of the usual venue of KeyArena in Seattle — as teams fight for a prize pool totaling almost $25 million.

Tournament Schedule

Wednesday, Aug. 15, through Saturday, Aug. 18: Group stage, starts at 9 a.m. PST

This year’s tournament changed format from previous Internationals, with teams qualifying for the main event through the Dota Pro Circuit tournaments played during the last year. The top eight teams qualified automatically for the International. Ten more teams received enough qualifying points to make it to the tournament as well.

At the start of the International, all 18 teams compete in round robin play to decide bracket seeding. The teams are split into two groups, with each team playing every other team in its group twice. The top four teams in each group advance to the upper bracket, while the fifth through ninth teams in each proceed to the lower bracket. The bottom team from each group is eliminated.

Monday, Aug. 20, through Saturday, August 25: The main event, starts 10 a.m. PST

The International proper is a double elimination tournament (teams that lose in the upper bracket are knocked down to the lower bracket, in which another loss means elimination.) Nearly all series will be best-of-three, with the only exceptions being the first lower bracket matches (best-of-one) and the grand finals (best-of-five).

Where to watch The International 8 live

Eager to ensnare the widest audience possible, Valve is providing many ways to watch the tournament (most of which are free!) There will be a number of streams available in different languages, each featuring different broadcasters commenting on the game. New players may find it helpful to watch the “Newcomer Stream,” a stream focused on walking viewers through the basics of the game and what is occurring during each match.

Watch in-game

Dota 2 is free-to-play, and that includes all the gameplay features available, including the ability to spectate games and watch replays. Dota’s spectator mode is also robust, probably one of the nicest of any video game. One can watch the game from the perspective of any broadcaster or players, or simply control the camera themselves. Spectator mode also provides real-time graphs and stats, allowing viewers to analyze the game as it progresses.

YouTube or Twitch

Maybe you don’t want to install the game to watch it — perhaps you simply want to watch it on your smart TV. Regardless of why you might be unable or unwilling to watch in-game, Valve has you covered. All the games will be streaming for free on their official Youtube and Twitch channels.

Replays

If you miss a game and want to see how it played out, Valve will provide replays both in-game and on the company’s official website. The replays also allow you to pause and rewind.

Go to a pubstomp

Like classic sports, esports are just a bit more fun to watch with a pint in hand, surrounded by cheering friends. Thanks to some enterprising bar owners, you can get that experience while watching TI5. The International’s website has a list of pubs that will be showing the tournament, making it easy to search for locations in your area.

Notable Teams

Team Liquid

A long-running esports organization that competes in a number of games, Team Liquid managed to fight its way through 2017’s The International despite things looking dire at the start of the tournament. After its first main stage bout, Team Liquid found itself knocked down to the single elimination lower bracket. It clawed its way back with five straight wins, fighting through the lower bracket to emerge into the finals against a long-running rival: Chinese team Newbee. Despite a dominant run in the tournament, Newbee couldn’t handle its resurgent opponents, and Team Liquid became the champion of last year’s TI7. This year, Team Liquid is the defending champion, which paints a massive target on its back — especially because Newbee is back this year, as well.

Newbee

Newbee took the championship spot in 2014, but struggled after some bad breaks and a tough TI5. Things were tough for a few years, until Newbee adjusted its roster and came back with a vengeance in the 2017 tournament win. “Vengeance” is a defining theme for Newbee this year, as well. The team was a powerful force in the TI7 tournament, blasting its way through the upper bracket, until it came up against Team Liquid in the finals. Newbee had struggled against Team Liquid for a while — it hasn’t beaten its rival since 2016 — and Team Liquid proved to be too much in The International as well. Newbee took second in 2017, but maintained its full team from last year and is out for revenge in in TI8.

Virtus.pro

Virtus.pro struggled in its early years of Dota 2 play, even dropping out of the game on two different occasions, but formed a new five-player team in 2016 to become something more. The Russian team has been incredibly dominant in the run-up to TI8, winning much more than any other team in the Dota Pro Circuit tournaments throughout the year. In fact, Virtus.pro has been such a force in the DCP that it garnered more than twice the qualifying points of the next best team, Team Liquid (last year’s winner of The International), and has taken home nearly $1 million more in winnings, as well. The team has been on a roll since adding RodjER, who competed in TI7 for Team Empire, in February, winning the ESL One Kowtice in February, the Bucharest Major in March, and ESL One Birmingham in May. Notably, they placed second in the China Dota2 Supermajor in June — a loss to Team Liquid, creating an interesting dynamic for a rematch at TI8.

Women may be immune to brain damage from cosmic rays, study finds

All things considered, outer space is a pretty terrifying place. It’s utterly silent, unfathomably vast, and it experiences weather extremes that make Earth’s seem mild in comparison.

And then there’s the radiation. We’re pretty much protected from hazardous levels galactic cosmic rays (GCRs) by our planet’s magnetic field but, just past low orbit, high-energy protons and charged particles can cause serious health and cognition problems.

But new NASA-funded research out of the University of California, San Fransisco and Brookhaven National Laboratory in New York suggests that not everyone’s brain is impacted by cosmic rays. In fact, the brains of female astronauts may be completely immune. In a paper published earlier this month in the journal Brain, Behavior, and Immunity, the researchers showed that female mice are immune to the cognitive damage that results from simulated space radiation. The study may pave the way toward treating this hazardous consequence of space travel.

“These results demonstrate that female mice are protected from the deleterious consequences of deep space exposure,” Susanna Rosi, a neuroscientist at UCSF and one of the study’s lead authors, told Digital Trends. “More in detail, we found that male mice develop a large range of cognitive deficits that are not present in females after exposure to galactic cosmic ray simulation.”

These cognitive deficits included changes in sociability, social memory, anxiety-like behaviors, and memory.

“When we look carefully in the brain we found fundamental differences between male and female,” Rosi said. Only male brains had an increase in inflammatory cells and a loss of neural synapses. “These results are compelling because they show fundamental sex differences.”

GCRs are not an immediate concern for today’s astronauts. The International Space Station is still within low-Earth orbit and no human has made it beyond the planet’s magnetic field since the Apollo missions. But with the way the new space race is shaping up, we may soon be headed back to the moon and Mars, where protection from cosmic rays is a top priority.

Rosi and her lab, including postdoctoral researcher and first author of the study, Karen Krukowski, have put forward the hypothesis that inflammatory cells called microglia account for the disparity between female and male mice by protecting female but not male brains. However, it’s unclear if or why this is the case.

The researchers note that this is just the beginning of what is likely to be a long investigation into safety measures for future space missions. They will continue to test more complex combinations of simulated space radiation and research ways to modify microglia to potentially treat these cognitive deficits.
