While he was examining algae from a nearby lake through his homemade microscope, a creature "with green and very glittering little scales," which he estimated to be a thousand times smaller than a mite, had darted across his vision. Two years later, on October 9, 1676, he followed up with another report so extraordinary that microbiologists today refer to it simply as "Letter 18": Van Leeuwenhoek (lay-u-when-hoke) had looked everywhere and found what he called animalcules (Latin for "little animals") in everything. He found them in the bellies of other animals, his food, his own mouth, and other people's mouths. When he noticed a set of remarkably rancid teeth, he asked the owner for a sample of his plaque, put it beneath his lens, and witnessed "an inconceivably great number of little animalcules" moving "so nimbly among one another, that the whole stuff seemed alive." After a particularly uncomfortable evening, which he blamed on a fatty meal of hot smoked beef, he examined his own stool beneath his lens and saw animalcules that were "somewhat longer than broad, and their belly, which was flat-like, furnished with sundry little paws"--a clear description of what we now know as the parasite giardia. With his observations of these fast, fat, and sundry-pawed creatures, Van Leeuwenhoek became the first person to ever see a microorganism--a discovery of almost incalculable significance to human health and our understanding of life on this planet.

Back in 2015, before Brexit, before Trump, before Macedonian internet trolls, before QAnon and Covid conspiracy theories, before fake news and alternative facts, the disagreement over the Dress was described by one NPR affiliate as "the debate that broke the internet." The Washington Post called it "the drama that divided the planet." If you buy something using links in our stories, we may earn a commission. This helps support our journalism. The Dress was a meme, a viral photo that appeared all across social media for a few months.

Facebook is testing a new video speed dating app called Sparked which emphasises'kindness' and a'positive dating experience' between users. Developed by the social media giant's New Product Experimentation (NPE) team, the app requires users to have a Facebook profile, The Verge reported. The app requires users to type out what makes them a kind dater when signing up, and these responses will reportedly be "reviewed by a human at Sparked" before people can go on the video dates. The social media giant noted that Sparked would not contain any public profiles, or swiping, or DMs, and is likely to be free to use. Users also have to choose whether they want to date men, women, or nonbinary people, according to The Verge which reportedly accessed the app's website.

Facebook is testing a video speed dating app that lets potential matches meet for four minutes to see'if sparks fly.' Called Sparked, the service is described as'video dating with kind people' and promises no swiping, no DMs and is free to use, but requires a Facebook profile to create an account, as first reported on by The Verge. The app cycles users through four-minute sessions, then a 10-minute second date can be setup and after that, the conversation can move to Instagram, iMessage or email.

Facebook is dipping its toes further into the world of dating. The company's New Product Experimentation (NPE) Team, which creates experimental apps, has released a video speed-dating app called Sparked. It sounds a little like both Chatroulette and the video chat features that major dating apps have added since the onset of the COVID-19 pandemic. You'll go on a rapid-fire series of four-minute dates and, if you and the other person enjoy your time together, you can go on a 10-minute second date. At that point, you'll need to exchange contact details if you want to stay in touch.

Last week Leticia Stoc was watching TV at her home in Amsterdam and texting her friend, when something started to bother her. You may know the feeling. She was worried the friend didn't like spending time with her, so she sent another message saying so point blank. It's because I'm weird, she added. The friend quickly reassured her.
