The dinosaurs may have been extinct for more than 65 million years but scientists have suggested that they could still exist as aliens on other planets. Researched published in the Monthly Notices of the Royal Astronomical Society suggests that dinosaurs might not only be on other planets but that we could also find them. The study suggests that if scientists researched compounds that are not currently on Earth but ones that were around during the age of the dinosaurs then it may yield some results. One key element that scientists believe could unlock what would be a groundbreaking discovery is oxygen. The levels of oxygen on Earth at the moment are around 21 per cent but during the time of dinosaurs it was higher at 30 per cent. This, in theory, allowed the dinosaurs to flourish and rule the planet for millions of years. The study suggests that if similar levels of oxygen can be discovered on faraway planets then the conditions could be right for alien like dinosaurs to exist. The study's co-author Lisa Kaltenegger said in a statement: "Modern Earth's light fingerprint has been our template for identifying potentially habitable planets, but there was a time when this fingerprint was even more pronounced — better at showing signs of life." She adds: "This gives us hope that it might be just a little bit easier to find signs of life — even large, complex life — elsewhere in the cosmos." One clue that could unlock this discovery which scientists are looking for are signs of a Phanerozoic stage on a planet which would allow creatures like dinosaurs to evolve. The study's lead author, Rebecca Payne of Cornell University, said: "The Phanerozoic is just the most recent 12 per cent or so of Earth's history, but it encompasses nearly all of the time in which life was more complex than microbes and sponges. These light fingerprints are what you'd search for elsewhere if you were looking for something more advanced than a single-celled organism." If they are successful in finding these conditions on other planets then Kaltenegger believes it could lead to the discovery of dinosaurs that have never been found on Earth. "Hopefully we'll find some planets that happen to have more oxygen than Earth right now because that will make the search for life just a little bit easier," she said. "And, who knows, maybe there are other dinosaurs waiting to be found." Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Among the 52 companies that MSCI categorizes as semiconductor makers, only Intel has avoided a share-price decline as the month draws to a close.

Researchers in China have invented a device that can connect people’s brains to a computer via their inner ear. The SprialE brain-computer interface (BCI), developed by a team from Tsinghua University in Beijing, uses a flexible in-ear material to establish a digital connection to the brain. It follows recent advances into BCI technology, which has seen company’s like Elon Musk’s Neuralink test brain chips capable of reading the minds of pigs and monkeys. Ultimately, the technology could offer “full-bandwidth data streaming” to the brain. Unlike Neuralink’s device, the latest invention does not require surgery or other microneedle-based invasive methods to install, which the scientists claim make it suitable for daily use. Current methods of connecting BCIs via the ear involve support systems like earplugs or 3D printed attachments, however the spiral design means it can be slid in and out without blocking the wearer’s hearing. “The hollowness of SpiralE ensures that all subjects could hear audio stimuli in the outside world in real time,” the researchers noted, adding that its unique structure demonstrates that “natural and discreet wearable electronics can be integrated into real-life applications.” The research was detailed in a study, titled ‘Conformal in-ear bioelectronics for visual and auditory brain-computer interfaces’, was published in the scientific journal Nature Communications. The technology could allow applications like translating thoughts into text, control digital objects with thought alone, or even augmenting human memory. A 2019 report from the Royal Society said the technology had the potential to “transform medicine and fundamentally change how we interact with technology and each other”, however it warned that BCIs raise critical ethical concerns relating to privacy and human rights. “Neural and brain-computer interfaces may challenge the very essence of what it is to be human,” the report stated. “Working out how, and even if we want to use them requires an open and inclusive debate involving many voices and all sectors of society.” Read More What is superintelligence?

Some female frogs will go to the extent of faking their own deaths to avoid sex with their male counterparts, a new study has revealed. Researchers in Berlin and Finland focused on the European common frog for their investigation owing to the often alarming nature of the species' mating process. The short breeding season means that several males often cling to a single female – in a pile-on that can cause the female to drown. (So, pretty understandable that they might want to avoid this.) For the research published in the Royal Society Open Science, European common frogs were collected and divided into tanks where there were two females and one male in each. Before this research, it was thought that the females couldn't defend themselves against the aggressive amorous act. However, a number of the wily participants displayed the three avoidance behaviours. A rotation technique to escape mating was a popular option – carried out by 83 per cent of the females. While nearly half of them (48 per cent) mimicked how male frogs sound to trick them into letting them go. In 33 per cent of the females, the researchers recorded a stiffening of arms and legs for two minutes, in a convincing bid to play dead. Out of the females who got mounted by a lustful male, almost half were able to escape thanks to at least one of these avoidance behaviours. “The smaller females also showed the full repertoire of behaviours more often than the larger females," the researchers noted, and younger females were more likely to pretend they were dead. However, question marks remain on whether the frogs fake their death as a conscious choice or whether it is a stress response or even a means to test the male’s strength and endurance. “I think even if we call this species a common frog and think we know it well, there are still aspects we don’t know and perhaps haven’t thought about," Dittrich explained to The Guardian.
