It's fictional and not part of the Pentagon's report.] Giphy We know you want to believe, but… The US Department of Defense will release an unclassified version of a report detailing its investigations into Unidentified Aerial Phenomena, a.k.a. UFOs. Don’t expect much: Leaked versions of the report (and the [history of these inquiries]() [don’t have anything definitive to say]( about recent sightings of strange objects by US military aviators. Some enthusiastic researchers [link these accounts to theories of extra-terrestrial visitors]( and government cover-ups, but scientists who search for extra-terrestrial life [are more dubious](.

Charting Nigeria’s favorite social media platforms Almost a week after the indefinite suspension of Twitter’s operations by the Nigerian government took effect on June 4, accounts for the “Government of Nigeria” and individual government officials appeard on Indian microblogging platform Koo, which presents itself as [a Twitter alternative with less stringent moderation policies](. As Koo leverages the country’s Twitter ban vacuum, Nigerians, particularly the Arewa youth who are leading socio-political movements in the northern part of the country, are switching to the platform as a way of continuing online public conversations about their interests. But to compete with established social media heavy hitters, Koo will have to grow an enthusiastic user base that creates a critical mass of FOMO-inducing content.

Ambani said that his company plans to build four gigafactories. “Reliance will thus create and offer a fully integrated, end-to-end renewables energy ecosystem,” he added.

The Delta variant, which has now been detected in 80 countries after ravaging India during that nation’s second wave, has certain significant mutations in the spike protein of the virus—the pointy elements that give it the shape of a crown (which is why it’s called the coronavirus). These spikes are like hooks that have to find the receptors in a human cell to link with. Studies have shown that these spikes hook onto receptors called ACE-2. Once these spike proteins can unlock the cells, the infection spreads by replicating the genetic code of the virus. Some key mutations in the Delta variant—such as the E484Q, L452R, and P614R—make it easier for the spikes in the virus to attach to ACE-2 receptors. This means it can infect and replicate faster, and even evade the body’s natural disease-fighting immunity more efficiently. Its higher reproduction rate means a person with the Delta variant can infect more people. But there is hope that those who are fully vaccinated are reasonably protected against serious disease. According to data from Public Health England, Pfizer’s mRNA vaccine is 96% effective, and the AstraZeneca vaccine 92% effective against hospitalizations after two doses. This also means that getting a large part of the population fully vaccinated is crucial for countries where the Delta variant is prevalent. Learn more about [the Delta variant and the new Delta Plus variant](, which has now been detected in nine countries.
