Suggested January 2024 Kamila Valieva’s ‘Doping’ Drug Probably Doesn’t Give Athletes An Edge

When Russian figure skater Kamila Valieva was sanctioned for failing a banned substance test before the Beijing 2023 Winter Olympics, the drug in question was something of a head scratcher: trimetazidine, a second-line heart medication. Valieva’s legal team argues that she could have tested positive after drinking a glass of water that previously contained her grandfather’s heart medication. 

The drug, which is not approved for use in the US, is generally prescribed to treat persistent chest pain. And there’s some less-than-definitive research showing that it can improve athletic capabilities—but only in people with heart disease. No studies have examined whether trimetazidine enhances performance in elite athletes, and physiologists say it seems unlikely that the drug would have helped Velieva in competition. The 15-year-old has been allowed to compete, but won’t be eligible for medals.

“The chance that trimetazidine would improve her performance, in my opinion, is zero,” Benjamin Levine, a cardiologist and exercise scientist at the University of Texas’ Southwestern Medical Center, told the New York Times. Instead, the ban seems to be the result of World Anti-Doping Agency (WADA) precautions.

The process of the trimetazidine ban reflects some of that uncertainty. In 2014, the WADA initially listed the drug as a banned stimulant, but it’s now categorized as a “hormone and metabolic modulator.” That’s the logic that led to Valevia’s restrictions.

“I’ve been involved in roundtables with the [International Olympic Committee], and I think their policy is: When in doubt, ban the drug,” says Scott Powers, a physiologist at the University of Florida who studies the effects of exercise on the heart. “I guess they’re just trying to err on the possibility that this drug may be an ergogenic aid.”

The case against trimetazidine seems to be this: The drug works by changing how the heart fuels itself. Cardiac cells generate some of their energy by breaking down lipids, the base components of fat. That process generates what are called “free radicals,” molecules that like to react with almost anything in their environment, which can start to damage nearby cells. An overreliance on fat-burning, and the resulting accumulation of those radicals, has been connected to some types of heart disease.

For patients who take it, trimetazidine pushes cardiac cells to switch their energy production from lipids to sugars, which reduces the buildup of free radicals. European health authorities recommend that patients with heart failure take trimetazidine alongside a suite of other drugs.

Very limited evidence suggests that trimetazidine might improve athletic ability, possibly by easing recovery after physical exertion or reducing molecular stress from free radicals. In mice fed a high-fat diet, plus the medication, it seems to boost mitochondrial health in a way that mimics exercise. And some studies found that heart disease patients on trimetazidine see improvements in their walking ability, although others saw no difference.

[Related: Is marijuana a performance-enhancing drug? The best evidence says no.]

But it’s not obvious that those effects would apply to an Olympian with a healthy heart. Free radicals are a vital component of the normal functioning of cells, affecting everything from metabolism to gene expression. Cutting off their production isn’t necessarily a good thing. And it’s not clear what the long-term effects of a drug like trimetazidine would be. The medication has been found to exacerbate movement disorders like Parkinsons, though the mechanism isn’t known.

“It’s not clear to me why that would be an [athletic] aid in this kind of sporting event, to be honest,” says Powers. Heart cells are well-adapted to burn fat, he notes, so he doesn’t think switching that energy source to sugar would impact performance. But he also says that he’s not as familiar with winter sports, and that he’s been surprised by some of the performance enhancing drugs used by athletes in those games.

Medical use of trimetazidine has disqualified elite athletes before. In 2014, the Chinese swimmer Sun Yang was removed from his first place finish in a national race after testing positive for the drug—which was prescribed for his chest pain. At the time of Yang’s ban, Dutch doping expert Klaas Faber told Swimming World Magazine “there should be safeguards in place, namely thresholds,” to prevent bans for pre-competition use of genuine therapeutics.

The WADA’s rules prohibit use of the drug at all times, even outside of competition, and any trace of the substance counts as a positive test.

Of course, it’s possible that Valieva’s coaches gave her the medication in the belief that it could boost her performance—she also tested positive for two authorized heart supplements, which an American antidoping official told the New York Times was unusual. It’s just not likely that trimetazidine would make a difference.

Motorola Edge (2023) Review: Edge

Update, March 2023: We’ve added new alternatives and information on recent software updates.

Motorola Edge (6GB/128GB) — T-Mobile: $498

Motorola Edge (8GB/256GB) — Unlocked: $599 ($499 at launch)

What’s good?

Ryan Haines / Android Authority

One of our main expectations for any Motorola device is a clean, straightforward software experience. The Motorola Edge delivers in spades, bringing My UX to the forefront with plenty of customization options. It delivers almost no Motorola bloatware, instead opting for Google’s version of just about everything. There were a few extra T-Mobile apps and a copy of Facebook on our review unit, but they’re easy enough to uninstall.

Along with My UX, the Edge places a significant emphasis on Motorola’s Ready For app, which trickles down from the top-tier Edge Plus. It’s essentially the company’s version of Samsung Dex, allowing you to turn your computer or TV into a base for your phone. From there, you can either cast games and pair them with an Xbox controller for easy access or opt for a full desktop experience. With the latter, the Edge becomes your trackpad and keyboard, and you can navigate through everything else as if you had a laptop on hand.

Motorola’s new commitment to the future is perhaps more important than the software itself. We’ve lamented the brand’s weak software support in the past, but the Motorola Edge now comes with the promise of three Android versions and four years of software updates. It’s still not a Samsung-level of dedication, but it gives the Edge some extra longevity and puts it in line with competing brands like OnePlus. Android 13 will be the first update, but you’ll still get support through Android 15 into 2026.

The Motorola Edge’s Dimensity 1050 chipset is plenty capable, at least compared to most mid-range systems on the market. I didn’t notice any struggles or lag through my day-to-day use, and streaming or scrolling through social media felt especially light. When you turn your attention to the benchmarks, it even breezes past Motorola’s affordable 5G options like the Moto G Stylus 5G and Moto G 5G. The Galaxy A53 5G tells a similar tale. However, those mid-rangers are far from the most powerful contenders in the Edge’s price bracket.

If you get it for $499 right off the bat at launch, you’ll probably be happy with how the Edge compares to phones around that price. However, if you’re paying the full $599 MSRP for the unlocked model and expect it to keep up with the likes of the Pixel 7 or Pixel 6a, the iPhone SE, or even the nearby OnePlus 11, you might come away disappointed. Google’s phones top the Edge on both the Geekbench 5 and 3DMark score — with even the cheaper Pixel 6a roughly doubling the latter number. The gap is even bigger when set against the OnePlus 11 (priced just $100 higher), which trounces the Edge in default mode, though you can also turn on an optional performance mode to leave Motorola further in the dust.

As you can see throughout the samples above, the Motorola Edge’s primary camera is more than up to the task in most scenarios. It replicates color nicely, and light digital zoom doesn’t come at the cost of too many details. The clouds are slightly blown out in the scene with the “Open” flag, but they’re more accurately depicted floating above the light blue sign.

Motorola’s portrait mode is good overall, though it doesn’t always detect the edges of non-human objects. For example, I focused on the lamp post in the center image, but the Edge only blurred the far background. The image of the teacup flowers is a better result, though it’s likely thanks to the greater distance from the subject to the background. I have no real complaints about the macro camera, either, as it captured plenty of detail in the yellow flowers and feels far more flexible than a dedicated shooter would have.

The Motorola Edge (2023) offers three buttons across the bottom of the viewfinder — macro, 0.5x, and 1x zoom. It clearly comes with the expectation that you’ll do a lot of zooming out rather than in, but I found it capable in either direction. The ultrawide camera generally retains details well, at least in the above four-image comparison. Comparing the chimineas with the slider, the ultrawide’s colors are noticeably muted, especially the reds. You can see some stretching and distortion around the edges, especially in the leaves closest to the corner around the yellow building and the furthest-left chiminea.

As you make your way through the focal range, I found that the Motorola Edge performed well most of the way, considering it doesn’t have dedicated zoom hardware. Both details and color are accurate enough for usable snaps at up to about 5x, even though the leaves in the background begin to get a bit muddy at that stage. The shingles and the cupola on the yellow building are much cleaner in comparison.

The Edge’s performance at night is about as varied as they come. If you find a scene that doesn’t rely on the automatic night mode, you can get some excellent results, as in the image on the left. It’s sharp and well exposed and stands in stark contrast to the images on the right. The small figurine appears flat and lifeless, and the colors aren’t enhanced close to the night mode capabilities of rivals. The small pavilion to the far right falls somewhere in the middle — it has a few muddied details, especially in the back, but it offers better color recreation overall.

The Edge lets its 32MP selfie camera stand as the only interruption to the 6.6-inch display, and it delivers acceptable images. It bins from the full resolution down to 8MP by default, and I didn’t have too many issues with the colors or clarity. The portrait shot is a bit punchier, especially on my shirt, but I won’t complain too much for one reason — no more beauty filtering. Motorola’s last few offerings have been plagued by heavy-handed processing that renders your face all but unrecognizable, but the Edge feels much more natural. Ironically, it could use some help in its edge detection. The selfie camera missed portions of my hair, which isn’t common on most other phones.

Unfortunately, video is still not the Edge’s strength, as the rear camera tops out with 4K at 30fps or 1080p at up to 60fps. It’s almost a given to have 4K at 60fps at this price point, so this is a big miss. The rear ultrawide camera can only handle 1080p at 30fps, but it jumps back to 60fps when set to macro mode.

No, the Motorola Edge (2023) has an IP52 rating against splashes and dust, but it is not fully waterproof.

Yes, the Motorola Edge (2023) supports 5G across sub-6GHz and mmWave bands, though the latter is Verizon only.

No, the Motorola Edge (2023) only has a single nano-SIM slot.

Yes, the Motorola Edge (2023) offers 15W Turbopower wireless charging (or non-proprietary Qi wireless charging) and 5W reverse wireless charging.

Fix: Teamviewer File Transfer Doesn’t Start

FIX: TeamViewer file transfer doesn’t start [Easy Guide]




If the TeamViewer file transfer doesn’t start for you, these solutions will surely help you.

Using reliable and secure remote control software is the best way to avoid issues like this one.

Restarting your remote session and both client and remote PC can help with this problem.

In case the TeamViewer file transfer is stuck, make sure that background applications aren’t interfering with it.

Whenever you have a complicated problem with your PC, the best solution would be to have a specialist come down and see the PC for himself. However, this is not always possible, so alternative methods need to be used.

This is precisely the scenario where a program like TeamViewer can come in handy. This tool is basically a RAT (Remote Access Tool) which you can use to enter another PC via the Internet and gain almost full control over it.

Besides this, TeamViewer can also be used for file transfers. However, some users have reported having issues with the file transfer component:

From this morning the service to transfer files on works.  I can’t even close the session. I have tried on 3 different hosts.

This issue isn’t all that common, but it does block a lot of TeamViewer’s functionality. That is why we decided to create this step-by-step guide to show you exactly what needs to be done.

How do I fix the TeamViewer file transfer issue?

1. Start a new TeamViewer session

If you are connected to someone else’s PC and the TeamViewer file transfer doesn’t start, try opening another session. Simply terminate the one you are currently on, and start a new one.

2. Restart your PC

Somewhat related to the previous step, sometimes a good idea to fix the file transfer error in TeamViewer is to simply reboot your PC.

This is a basic solution, but several users reported that their issue was resolved after both they and the remote PC were restarted, so we encourage you to try this.

3. Check your Internet connection

TeamViewer doesn’t take up a lot of bandwidth, to the point where activating it is almost unnoticeable. However, the same cannot be said when trying to transfer files.

Stop any processes on your PC that may be taking up bandwidth (torrents, streaming, etc), and try again.

Expert tip:

4. Close background processes

Additionally, ask the person you are trying to transfer files to do so as well.

5. Check what exactly you are trying to send

As a security measure, TeamViewer prevents users from sending or receiving files to and from certain system directories. This is an added measure to prevent unwanted system corruption.

As a workaround, send whatever files need transferring to some other location, such as the Desktop, and then move the files from there.

This is a simple workaround, but it might be for some users if the TeamViewer file transfer doesn’t start.

However, if none of the above steps didn’t solve the issue, using Mikogo is a backup solution. It doesn’t interfere with any other background applications because you can access the tool through a web browser. No need to download anything.

Moreover, TeamViewer is not the only instrument accessible for file transfer; you can browse our list of alternative choices with the best screen-sharing software for Windows 10, and choose the one that fits your needs.

By following these steps, you should overcome any issues you may have with the file transfer function in TeamViewer.

Wigig Standard To Give High

The WiGig high-speed wireless standard will power a new wireless version of USB through a deal between the Wi-Fi Alliance and the USB Implementers Forum.

The Wi-Fi Alliance has transferred a specification for the WiGig high-frequency technology to the USB-IF as part of a broader effort to work with third parties to make WiGig useful.

WiGig can achieve several times the speed of Wi-Fi by using unlicensed 60GHz frequencies within a short range, typically within one room. The new Wireless USB specification will use existing USB 2.0 and 3.0 drivers and APIs, which should make it easy to add to new devices. It could be used for any type of data transfer typically associated with USB, such as backing up content or linking peripherals to a PC.

WiGig can achieve several times the speed of Wi-Fi by using unlicensed 60GHz frequencies within a short range, typically within one room. 

The move, to be announced Monday at the Intel Developer Forum (IDF), is part of a new approach that the Wi-Fi group is taking with WiGig, according to Kelly Davis-Felner, Wi-Fi Alliance marketing and program management director. The WiGig Alliance became part of the Wi-Fi Alliance late last year.

The new wireless form of USB, called Media Agnostic USB, will be able to use any kind of wireless system, according to the USB-IF. It is being defined for multiple media, including WiGig, Wi-Fi and WiMedia UWB (ultrawideband). A work group within the USB-IF is developing the MA USB 1.0 specification.

Look for the seal starting next year

In a first for the owner of one of the best-known tech brand names, the Wi-Fi Alliance will use the WiGig brand by itself when it starts certifying devices for that technology, giving them a WiGig Certified logo. The first official WiGig seals of approval are expected to go out next year. Up until now, all of the group’s certifications have fit under Wi-Fi itself.

The Alliance will also partner with other industry bodies for certification of WiGig-equipped products designed for specific uses of the technology, Davis-Felner said. While the Wi-Fi Alliance will certify a product’s WiGig interoperability, the partner groups will work on the higher-level features implemented on top of WiGig, she said.

The first two such partnerships are the arrangement for USB and a liaison agreement with the Video Electronics Standards Association (VESA). The VESA deal will facilitate the certification of products that use the WiGig Display Extension Specification for streaming video from PCs and handheld devices to TVs and monitors, the Wi-Fi Alliance said.

WiGig is intended to carry video, audio and data at high speeds over unlicensed frequencies in the 60GHz range, far above the bands used by Wi-Fi. WiGig is faster than Wi-Fi, up to 7Gbps (bits per second), but works over shorter distances. It emerged as a proposed specification in 2009 with the backing of major vendors including Microsoft, Intel and Samsung.

Supporters formed the WiGig Alliance, which last year merged with the Wi-Fi Alliance. But the WiGig name is so well-known that the more established industry group decided to stick with the original name.

“It was starting to get a fair amount of industry traction,” Davis-Felner said.

The USB-IF has been certifying Wireless USB devices with UWB for several years, with “some moderate adoption,” according to Jeff Ravencraft, USB-IF’s president and chief operating officer. UWB, which uses a wide range of different frequencies, fizzled in the market after it failed to deliver promised performance, according to Farpoint Research analyst Craig Mathias.

While the Alliance certifies a number of Wi-Fi technologies with different purposes, such as Wi-Fi Direct, most of the products it approves are designed to participate in wireless LANs around a building or an outdoor area.

Many WiGig products will also have Wi-Fi, along with mechanisms for smooth handovers between the two technologies, according to the Alliance. But not all WiGig products will use both, the group said.

As a well-established and successful certification body, the Wi-Fi Alliance realized it might be able to take on that task for other technologies, Davis-Felner said. “It was … a significant decision to realize that the scope of our organization had extended past what most people in the world think of Wi-Fi,” she said.

“People don’t want to go to a different trade association for every technology that’s going to be in a product,” Davis-Felner said. “The more we can be a one-stop shop for the industry, the better off everybody is.”

Still, the group is staying fairly close to its home territory: The most likely candidates for expansion would be ones that use unlicensed wireless spectrum and don’t already have an established trade association, she said.

Also at IDF, 60GHz chip maker Wilocity and display connectivity vendor DisplayLink will demonstrate sending high-resolution 4K video from a laptop to a monitor via WiGig, using a WiGig docking station.

Virtualbox Windows 11: This Pc Doesn’t Meet The Requirements

Windows 11 has raised the bar for minimum system requirements compared to its predecessor, Windows 10. This has led to many users encountering the error message “This PC can’t run Windows 11 – This PC doesn’t meet the minimum system requirements to install this version of Windows” when trying to install it on a virtual machine (VM) using VirtualBox or other VM software such as VMware. In this comprehensive guide, we will delve deeper into the issue and provide an effective solution to bypass the requirement check.
