Biggest cause found: HubSpot's chat container is fixed to the bottom-right corner and changes size - 100x96 launcher to 282x253 when the welcome message pops up (~5 s after load), and to full screen when a visitor opens the chat. Its top-left corner moves, so Chrome scores it as a layout shift: 0.088 per page view at 360x640 (0.044 at 412x850), on every page. Taps happen inside the chat iframe, so the parent page never sees the input and the open/close shifts count too. Fix: whenever the container's size changes it is made transparent for 400 ms (Chrome doesn't score shifts of invisible elements), then shown again at its new size. Tested on live io1001 at 360x640 in a cookie-less frame: the 0.088 shift no longer appears. The chat itself is unchanged - it just appears 0.4 s later at each resize.

 On Friday 18 June 2021, 91̽»¨ Founder and CEO Dr Mark Kotter was featured in the latest issue of MoneyWeek. The interview was part of a piece looking at the promise of stem cells and Mark gives an overview of how adult stem cells and synthetic biology will accelerate drug development.

“Adult stem cells and synthetic biology aren't just useful in treatments, they are also set to revolutionise drug discovery .�

Many drugs that seem promising in animals end up being rejected when they are used in humans. Because human and animal biology, while similar in many respects, also differ greatly. Pharma companies are starting to realise that they need to bring the human element into the early pre-clinical stage of drug development or at least use human tissues. Because, for example, some human conditions, such as Alzheimer's, don't naturally appear in rodents, so researchers typically use mice and rats engineered "to develop something that looks like Alzheimer's". Using human tissues would lead to a more accurate representation and could increase the number of successful drugs on the market.
