We use letters every day of our lives, but apparently, there's one lowercase letter that we do not recognise. Psychologists at Johns Hopkins University have discovered that most people aren't aware that there are two types of the lowercase letter g. One of them is the open tail 'g' which most of us would have written out by hand with its image comparable to "a loop with a fishhook hanging from it.

There were 38 volunteers in the study published by the Journal of Experimental Psychology: Human Perception & Performance and they were asked to list letters that they thought had two variations in print. In the first experiment, "most participants failed to recall the existence of looptail g" while only two people could write looptail g accurately. "They don't entirely know what this letter looks like, even though they can read it," co-author Gali Ellenblum said. Next participants were asked to look for examples of the looptail g in the text and were asked to reproduce this letter style after this and in the end, only one person could do this while half the group wrote an open tail g. Finally, those taking part in the study were asked to identify the letter g in a multiple-choice test with four options of the letter where seven out of 25 managed to do this correctly. So how can we know a letter but not recognised it? It could be to do with the fact we are not taught to write this kind of 'g," according to Michael McCloskey, senior author of the paper. "What we think may be happening here is that we learn the shapes of most letters in part because we have to write them in school. 'Looptail g' is something we're never taught to write, so we may not learn its shape as well," he said. "More generally, our findings raise questions about the conditions under which massive exposure does, and does not, yield detailed, accurate, accessible knowledge." In a play-along video on John Hopkin's YouTube channel, four different g's labelled from one to four appear on the screen where it asked viewers to guess which is the correct looptail 'g'. (*Spoiler ahead*) The correct answer is number 3. Meanwhile, this study has also led research to question the impact that writing less and using more devices has on our reading abilities. "What about children who are just learning to read? Do they have a little bit more trouble with this form of g because they haven't been forced to pay attention to it and write it?" McCloskey said. "That's something we don't really know. Our findings give us an intriguing way of looking at questions about the importance of writing for reading..." Have your say in our news democracy.

A TikTok that has a filter on to show what the world looks like to people who are colour blind has caused people to ponder whether they themselves are too after believing the filter to be "normal". Colour vision deficiency (CVD) is believed to affect 300 million worldwide, and around three million people in the UK (about 4.5% of the the country's population). The condition where people struggle to tell various colours apart affects approximately 1 in 12 men (8 per cent) and 1 in 200 women. Yellow, red and green are the colours which those with CVD struggle to distinguish and are known as 'red-green' colour vision. While 'blue-yellow' deficiency does too exist where blue, greens and yellows are trickier to differentiate, this is less common. A recent viral TikTok by Tess (@tessromie) used a filter that could filter that demonstrate how colourblind people view the world. In text captions she wrote: "Discovering how my colour blind husband sees the world." “I’m in shock and I’ll never recover," she added. @tessromie I’m in shock and I’ll never recover #colorblind #husband #dogvision Since sharing the video, it now has over 3.6m views with people flocking to the comments section where they realised they too may be colourblind. One person said: "...it literally looks normal to me." "Yo that’s how I see," another person wrote. Someone else added: "Yeah I seriously don’t notice a thing that's different, colorblind gang." "I'm colorblind and I literally watched the video over and over trying to figure out what they were talking about," a fourth person commented.

A spokesman for the White House National Security Council (NSC) has flatly rejected a report which claimed that China and Cuba have reached an agreement in principle to host a surveillance post. John Kirby appeared on MSNBC shortly after the publication of The Wall Street Journal’s report on Thursday; the report claimed that the cash-strapped Cuban government had accepted an offer by Beijing to set up a listening post on Cuban soil, within range of some US military installations. The article went on to claim that such a listening post could theoretically scoop up communications across much of the southeastern United States. “Officials familiar with the matter said that China has agreed to pay cash-strapped Cuba several billion dollars to allow it to build the eavesdropping station and that the two countries had reached an agreement in principle,” read the report. It continued: “An eavesdropping facility in Cuba, roughly 100 miles from Florida, would allow Chinese intelligence services to scoop up electronic communications throughout the southeastern U.S., where many military bases are located, and monitor U.S. ship traffic.” But Mr Kirby said that the Journal’s assertions were inaccurate when confronted by NBC’s Andrea Mitchell. "China and Cuba have now reached a secret agreement, we’re told, for China to establish an electronic facility which would allow Chinese intelligence agents to scoop up electronic communications throughout the southeastern US,” Mitchell began to Mr Kirby. “I’ve seen that press report, it’s not accurate,” Mr Kirby contended. “What I can tell you is that we have been concerned since day one of this administration about China’s influence activities around the world, certainly in this hemisphere and in this region, we’re watching this very, very closely.” Mitchell tried again: “You’re saying it’s not accurate that they’re planning this?” “I’m saying we’ve seen the report, it’s not accurate,” said Mr Kirby in response. It was a much stronger statement than he himself had made to the Journal initially. The paper quotes him as saying in response to their request for comment, “While I cannot speak to this specific report, we are well aware of – and have spoken many times to – the People’s Republic of China’s efforts to invest in infrastructure around the world that may have military purposes, including in this hemisphere.” “We monitor it closely, take steps to counter it, and remain confident that we are able to meet all our security commitments at home, in the region, and around the world,” he added in that statement. At a news briefing on Thursday, a spokesman for the Pentagon echoed Mr Kirby’s denial. “I’ve seen that reporting, I can tell you, based on the information that we have, that that is not accurate,” said Air Force Brig Gen Pat Ryder. The report’s publication comes at a time of tension between Washington and Beijing, with both sides accusing the other of purposefully inflammatory actions. Some of those actions have included trips to Taiwan by senior US officials, which have enraged the Chinese government as they mark the US’s continued defiance of China’s claims of sovereignty over the island. It also comes as many in the US, particularly on the left, argue that the time has come for an end to the US embargo of Cuba, the socialist nation shunned by the US since the Cold War, when it was firmly allied with the Soviet Union. The decades-long trade prohibition has left Cuba’s economy in a delicate state, and many argue serves no purpose in the modern era.
