If you’re anything like us, you were probably absolutely obsessed with dinosaurs as a child. However, did you ever stop to think about the sheer number of dinos that were wandering around the planet before they met their untimely end at the hands of an asteroid? A new study has been published which states that a whopping 1.7 billion T-Rex roamed the Earth in total across the Late Cretaceous period. It comes after researchers calculated their average lifespan, which measured up to a whopping 40 feet in length and 12 feet in height. Sign up to our free Indy100 weekly newsletter They cross referenced this with the number of eggs which survived and the sexual maturity of the animals to come up with the figure. It’s a huge number, but it’s actually far less than previously thought. A previous study from 2021 estimated that there were 800 million more of them that existed between about 90 to 66 million years ago. The research was published in Palaeontology, and evolutionary ecologist Eva Griebeler from the Johannes Gutenberg University of Mainz in Germany wrote about the findings. "Unlike my model, the generation time as well as life expectancies, gross reproduction rates, and reproductive values of individuals calculated from the previous model all strongly contradicted our current understanding of the biology of T. rex and of other theropods,” she said. "Their values also disagreed with those of large extant reptiles, birds, and mammals. All of these shortcomings of the previous model favor the assessment of individual and population characteristics of T. rex and of other extinct species using my model." Griebeler also explained how the findings suggest a lower T-Rex survival rate, as well as fewer generations of the animal and less egg laying. "All of these shortcomings of the previous model favor the assessment of individual and population characteristics of T. rex and other extinct species using my model," she wrote.

SpaceX’s Starship blew itself up in the air, Elon Musk’s private space company has said. Starship underwent its second flight test over the weekend, when the company attempted to send the rocket almost into orbit and then have it land in the ocean. It completed the first part of that mission – but disappeared around eight minutes into its flight. Now the company has confirmed that it lost data from the flight at that moment, which came near the end of the burn of the second stage of the rocket. At that point, the spacecraft used a “safe command destruct” that meant that it caused itself to explode in the air, the company said. It did not say why that had been issued, but did indicate that it had been “appropriately triggered based on available vehicle performance data”. SpaceX noted that until that moment the flight appeared to have been going as planned. The Super Heavy Booster on the bottom of the spacecraft completed a full burn for the first time, for instance, and the two pieces of Starship separated successfully. The booster also managed to flip after it had separated from the upper part of the rocket, SpaceX said. It started another burn then but then “experienced a rapid unscheduled disassembly”, as SpaceX refers to explosions. That came three and a half minutes into the flight and happened around 90 kilometres above the Gulf of Mexico, SpaceX said. The company said that the explosions would prove useful in adjusting future builds of the Starship spacecraft. Before the flight it had explicitly said that the launch was intended as a test and could go wrong – and it reiterated that “while it didn’t happen in a lab or on a test stand, it was absolutely a test”. “With a test like this, success comes from what we learn, and this flight test will help us improve Starship’s reliability as SpaceX seeks to make life multiplanetary,” SpaceX said. “Data review is ongoing as we look for improvements to make for the next flight. The team at Starbase is already working final preparations on the vehicles slated for use in Starship’s third flight test, with Ship and Booster static fires coming up next.” Read More SpaceX launches “limitless” ‘zero fuel’ engine into space SpaceX hints next Starship launch attempt could be soon SpaceX launches world’s most powerful rocket – and then it disappears

Twitter says it has launched new, more secure messages – but even chief executive Elon Musk has warned users not to “trust it”. The social network has long been working on encrypted messages, which ensure that messages cannot be intercepted while they are being delivered. That is already possible on most other major messaging platforms, such as WhatsApp and iMessage. Now Twitter has released what it says is the first step towards integrating that security technology into its own product. But it says that it is not fully safe, and that users should not rely on it to keep messages secure. “Early version of encrypted direct messages just launched,” Mr Musk wrote on Twitter. “Try it, but don’t trust it yet.” On its support pages, Twitter’s aim is that “if someone puts a gun to our heads, we still can’t access your messages”. But it says it is “not quite there yet” and still “working on it”. That suggests that the messages are not end-to-end encrypted. While messages are secured from some attackers, anyone at Twitter or with access to its servers may still be able to access them. What’s more, Twitter’s implementation comes with a host of other limitations. It is only available when both of the users are verified and pay for Twitter’s $8 a month service, and users must turn it on rather than it being enabled by default. The messages also cannot be sent to groups, include pictures or other attachments, cannot be joined by new devices, are only supported on a limited number of devices per account and do not have proper protection against certain cyber attacks. When those various conditions are satisfied, users will be informed they are having an encrypted conversation by a message that appears within the chat. The other user’s profile picture will also show a lock icon over it. Twitter said that it would be updating the feature to remove some of those limitations, and would provide more information about the technology underpinning it in releases later this year.

A new report claims that Strava could be used to track people down – despite the platform’s efforts to make their data anonymous. Strava is a fitness tracking platform that allows people to log their exercises as well as engage with other based on their workouts. But it also includes other tools, such as its heatmap feature, which is intended to anonymously gather together people’s journeys and show them on one map. The tool is intended to allow people to see which parts of the world are particularly active, which can be helpful for finding particularly good areas for workouts or trips. But it can also be used to find out people’s personal information, according to a new report. That heatmap data is anonymised, so that it shows more general trends and cannot be used to track specific people who might mark their routes private. But the new research suggests that it is possible to de-anonymise that data, at least in some cases, to work out who lives where. The paper, published by three computer science researchers at North Carolina State University, says that “the home address of highly active users in remote areas can be identified, violating Strava’s privacy claims and posing as a threat to user privacy”. They detailed a complicated process that they claimed was able to find addresses and then combine that with other data from Strava to find the home address of a certain individual. In short, they were able to use the heat map to identify locations where people lived, and then take other location data to work out who might live at that specific house. The attack will not work on everyone: they need to live in remote areas where people’s houses stand on their own, those users need to have the heat map setting switched on, and might run in patterns that do not identify their home addresses, for instance. But the researchers claimed that a significant number of users could be identified based on publicly available information on Strava. That is a “violation of user privacy”, the researchers said. And it could also pose a threat to those users, by allowing people’s addresses to be made public, and then matched to certain activities, such as when they work out or where they tend to travel. The researchers suggested two ways to avoid the attack. One would be to remove heat map data that is clearly near a home, and another would be to add Strava’s existing “privacy zones” tools that block out data from certain locations to its heat map, which is not currently the case. Strava said that it looks to ensure users’ data stays private, and suggested that people concerned about potential issues turn off the use of aggregated user data on their account. “The safety and privacy of our community is our highest priority. We’ve long had a suite of privacy controls (including Map Visibility Controls) that give users control over what they share and who it’s shared with,” the company said. “Strava does not track users or share data without their permission. When users share their aggregated, de-identified data with the Heatmap and Strava Metro, they contribute to a one-of-a-kind data set that helps urban planners as they develop better infrastructure for people on foot and bikes, and makes it easy to plan routes with the knowledge of the community. “The Global Heatmap displays aggregated data from a subset of Strava activities and will not show ‘heat’ unless multiple people have completed an activity in a given area. Any Strava user who does not wish to contribute to the Heatmap can toggle off the Aggregated Data Usage control to exclude all activities or default their Activity Visibility to be only to themselves (’Only You’) for any given activity. “We are consistently strengthening privacy tools and offering more feature education to give users control over their experience on Strava. This includes simplifying our Privacy Policy with our Privacy Label at the top.” Read More Breakthrough could soon allow us to actually use quantum computers, scientists say Three and Vodafone are merging.
