A few weeks ago, we heard the first reports about Lenovo's Legion Pro, the company's planned answer to handheld PC gaming machines like the Steam Deck and ROG Ally (not to mention the upcoming Ayaneo Kun). Now, the first photos of the device (via Windows Report) show at least one major feature that should set it apart from that competition: Switch-style detachable controllers.

The Legion Pro wouldn't be the very first portable PC gaming device with removable controllers; the crowd-funded OneXplayer sported a similar design last year, for instance. But few other PC-based portables have similarly mimicked the Switch Joy-cons in their ability to slide smoothly off from the main screen of the system for detached play.

Combined with a nice, wide kickstand shown in the leaked images, you should be able to give your arms a rest by setting the bulky-looking Legion Pro's screen on a tabletop. The slide-off controls also mean you don't need to purchase and/or drag out a separate controller when docking the device to a TV or monitor (which we assume will be a main use case of the device's two USB-C ports). And completely detachable controls for each hand means you can keep your hands as far apart as you want while you hold each "half-controller" separately (one of our favorite unique use cases on the Switch).

People who enroll in genetic studies are genetically predisposed to do so.

According to the Catalogue of Bias, ascertainment bias occurs when a sample being studied is not representative of the target population. This can produce misleading or even false conclusions, and it can be hard to detect since it cannot usually be identified by examining the sample alone. This is why many studies try to use variables other than participation in the study to make sure their samples are as representative as possible.

Studies examining how a particular treatment affects a particular health outcome often try to handle ascertainment bias by adjusting for “covariates,” things like education level or socioeconomic status, that could affect health outcomes independently of the treatment. But Stefania Benonisdottir and Augustine Kong at Oxford’s Big Data Institute have just demonstrated that we can determine if genetic studies are biased using nothing but the genes of the participants.
