The human body is a marvel of science and researchers have discovered a strange reoccurring mathematical pattern within its cells. Our bodies are made up of a massive variety of individual cells with countless different functions, from neurons in our nervous system to the oxygen carriers that all work in harmony to keep us alive. Experts from scientific research institutions in Germany, Canada, Spain, and the US have worked together on a study to determine just how many cells of each type there are in the human body and the results are staggering. They found that most adult males possess around 36 trillion cells, while adult females have in the region of 28 trillion cells. For a 10-year-old child, they have around 17 trillion. Interestingly though, scientists discovered that, regardless of the total number of cells, if they are grouped according to their function, the proportions for each individual remain the same. The researchers explained in their findings: “These patterns are suggestive of a whole-organism trade-off between cell size and count and imply the existence of cell-size homeostasis across cell types.” Scientists believe there is a natural balancing act at play between different cell types with new cells being produced to maintain the balance. The body produces fewer larger cells (such as muscle fibres) and more smaller cells (like blood cells). It is hoped that future studies will be able to uncover exactly how this happens and how bodies seem to naturally regulate cells. They explained that all cells are perfectly sized for their roles and any deviation from their scale can indicate the presence of disease. Experts have made their data, analysis and results public in the hopes that future studies into biology will be able to utilise their research.

Google Bard, the tech giant’s generative AI platform, can now link with other Google services such as Gmail, Maps and YouTube in order to provide more in-depth responses to prompts from users. Launched earlier this year, Bard is part of the new wave of AI-based chatbots which offer detailed written replies to questions and queries. Google has now announced a major update to the program, called Bard Extensions, which will allow users to link other Google services to collaborate with Bard to provide a response to a prompt – for example, when asking Bard to help plan a holiday, users can ask Bard to get the dates that work for family members from Gmail, use Google Maps to get directions to the airport and find YouTube videos to watch about the best things to do at the destination. It said the update made Bard “the most capable” version of the program so far and would help more people use the app to collaborate. The tech giant said the update would have a strong focus on user privacy, with users required to actively give permission to Bard to access their Google services, and any content lifted would not be reviewable by a human unless the user specifically asked Bard to flag it for review. In a further expansion of the chatbot, Google said it would now also enable users to double-check the responses they receive from Bard using a new “Google it” button, which will check the response against linked Google search results and highlight passages it is confident about the validity of, as well as those where it found differing results. Some experts have raised concerns about the possible spread of misinformation within generative AI platforms, warning some information is being presented to users in an authoritative way when it may be based on inaccurate or outdated information used to train such chatbots. A report by the UK’s Competition and Markets Authority (CMA) published on Monday which looked into the potential impact of the AI market noted that without proper guiding principles, people and businesses could be harmed through exposure to significant levels of misinformation and AI-enabled fraud. In a blog post on the updates to Bard, Google’s director for product management of Bard, Yury Pinsky, said: “One of the biggest benefits of Bard, an experiment to collaborate with generative AI, is that it can tailor its responses to exactly what you need. “For instance, you could ask Bard to start a trip planning doc for you and your friends, draft up your online marketplace listing, or help explain a science topic to your kids. And now Bard is getting even better at customising its responses so you can easily bring your ideas to life. “Today we’re launching Bard Extensions in English, a completely new way to interact and collaborate with Bard. With Extensions, Bard can find and show you relevant information from the Google tools you use every day — like Gmail, Docs, Drive, Maps, YouTube, and Google Flights and hotels — even when the information you need is across multiple apps and services.” Elsewhere in the update, Google also confirmed that when a link to a Bard conversation is shared online, others will be able to click on that link and continue the same conversation themselves.
