It might sound more like the kind of idle daydream billionaires like Elon Musk would have, but could flooding the Sahara actually be the best way of tackling climate change in the future? The idea of creating a new “sea” in Africa is being discussed, and it’s not the first time that the notion of a great oasis in the Sahara has been discussed among the scientific community. As the ongoing climate crisis continues to worsen, the notion of flooding vast areas of the desert is being returned to once again [via IFL Science]. A new “sea” was first proposed following the study of the Messinian salinity crisis – which saw a dried-out area of the Mediterranean rejuvenated by the Zanclean flood, reconnecting the Mediterranean Sea to the Atlantic Ocean around 5.33 million years ago. Sign up to our free Indy100 weekly newsletter Given how the Mediterranean was transformed by the flood, the idea of flooding the Sahara to achieve similar results has been thrown around in the scientific community as far back as 1877, the Scottish engineer Donald McKenzie suggested flooding the El Djouf basin in Western Africa. The idea is now returning to popularity as the world looks for solutions to the climate crisis. One proposal centres on the Middle East’s Dead Sea and flooding the area using water from the Red Sea to the Dead Sea Depression. A vast sea in Africa could represent a hugely innovative step towards tackling climate change and fostering a new hub of life – but even the people suggesting work such a project acknowledge just how expensive and dangerous it is. Even Y Combinator is a US startup accelerator who has described “desert flooding” as “risky, unproven, even unlikely to work”. Only time will tell whether the notion of a new sea in the Sahara coud ever work, or whether it’ll remain the stuff of dreams. Have your say in our news democracy.

Nearly half of all internet traffic came from bots last year, according to new research. Figures from cyber security firm Imperva revealed a significant increase in automated and malicious web activity in 2022, with the proportion of human traffic falling to its lowest level in eight years. The company noted that so-called “bad bots” were at their highest level since it started tracking the trend in 2013. Bot activity is expected to increase even further this year, the researchers claimed, due to the arrival of generative AI tools like OpenAI’s ChatGPT and Google’s Bard. “Bots have evolved rapidly since 2013, but with the advent of generative artificial intelligence, the technology will evolve at an even greater, more concerning pace over the next 10 years,” said Karl Triebes, a senior vice president at Imperva. “Cyber criminals will increase their focus on attacking API endpoints and application business logic with sophisticated automation. As a result, the business disruption and financial impact associated with bad bots will become even more significant in the coming years.” Bad bot activity can include anything from spam that clogs up email inboxes, to advanced systems that carry out brute force attacks to hack into people’s emails or online accounts. Some bots even mimic human behaviour in order to avoid being detected by security software. Another worrying trend noted in the report was the rise of bots used in warfare, with a 145 per cent spike in automated attacks targeting Ukrainian web applications in early 2022. These were likely designed to disrupt the country’s critical infrastructure, ranging from energy and telecom, to transport and financial sectors. “Every organisation, regardless of size or industry, should be concerned about the rising volume of bad bots across the internet,” said Triebes. “Year-over-year, the proportion of bot traffic is growing and the disruptions caused by malicious automation results in tangible business risks – from brand reputation issues to reduced online sales and security risks for web applications, mobile apps, and APIs.” Read More Why tech bosses are doomsday prepping ChatGPT is finally connected to the web 75% of Irish data watchdog’s GDPR decisions since 2018 overruled – report Nasa’s AI gives ‘30 minutes of advance warning’ before solar superstorms strike Earth

A fifth-grade teacher said she is being investigated by the Florida Department of Education after she showed her students "Strange World," a 2022 animated Disney movie featuring a character who is biracial and gay.

A scientist has broken the world record for living underwater after spending 74 days living in a habitat 30 feet (9 metres) below a Florida lagoon. Former naval officer Dr Joseph Dituri is the first person to live that long that far underwater without depressurisation, with plans to remain in Jules’ Undersea Lodge in Key Largo until 9 June as part of a 100 day mission dubbed Project Neptune 100. The mission combines educational outreach with medical and ocean research, with scientists keen to see what impact sustained exposure to such pressure will have on the human body. One hypothesis is that the increased pressure – roughly 1.6-times that of the surface pressure – will lead to improvements in health, while also potentially having an impact on key indicators related to disease and longevity. “We know for sure that when you’re exposed to about half the pressure that I am right now, you double the number of circulating stem cells,” Dr Dituri told The Independent via video chat in April. “I will have longer telomeres – potentially reversing ageing – and I will also gain bone density and muscle when I’m down here.” Scientists also estimate he may lose around an inch in height during the mission due to the pressure exerted on his body – in the same way that astronauts grow around 3 per cent taller after spending time in the weightlessness of space. Dr Dituri’s 74th day residing in the underwater lodge was similar to previous days spent there since he submerged on 1 March. The university professor, who also goes by the moniker “Dr. Deep Sea,” ate a protein-heavy meal of eggs and salmon prepared using a microwave, exercised with resistance bands, did his daily pushups and took an hour-long nap. Unlike a submarine, the lodge does not use technology to adjust for the increased underwater pressure. The previous record of 73 days, two hours and 34 minutes was set by two Tennessee professors – Bruce Cantrell and Jessica Fain – at the same location in 2014. “The record is a small bump and I really appreciate it. I’m honoured to have it, but we still have more science to do,” Dr Dituri said. “The idea here is to populate the world’s oceans, to take care of them by living in them and really treating them well.” While he says he loves living under the ocean, there is one thing he really misses. “The thing that I miss the most about being on the surface is literally the Sun,” he said. “The sun has been a major factor in my life – I usually go to the gym at five and then I come back out and watch the sunrise.” During his time underwater, Dr Dituri also claims to have discovered a brand new species. “We found a single-cell ciliate, a single-celled organism that we believe is a brand new species to science,” Dr Dituri said. “People have dived in this area thousands and thousands of times – it’s been here, we just didn’t look.” Additional reporting from agencies Read More Woman talks to past self in ‘trippy’ conversation after feeding childhood journals to AI Nearly half of all internet traffic is now bots, study reveals ChatGPT is finally connected to the web 75% of Irish data watchdog’s GDPR decisions since 2018 overruled – report

More than a week after educators first hit the picket line, the Oakland Education Association, which represents public school teachers in Oakland, California, announced Monday morning it has reached a tentative agreement with the Oakland Unified School District, ending the strike and sending some 35,000 students back to class.
