It’s happened to us all. Maybe you’re walking down the street, or sitting on the bus, or even just sending an email – then suddenly, you realise you’ve been here before. Déjà vu can be a puzzling thing. It literally means already seen in English, and it remains pretty mysterious as to why we feel it. Now, scientists have a couple of theories. Sanam Hafeez, a clinical psychologist, told Fox News: "It refers to the eerie and distinct feeling that one has already experienced the current situation or event, even though it’s a new and unfamiliar occurrence. "It feels like a powerful wave of familiarity with the present moment as if the person is re-living a past experience. "Some suggest it may be linked to how memories are processed in the brain, potentially involving delays or errors in memory retrievals." She added that it may be because the brain is processing information through multiple pathways at the same time, creating the illusion of a memory when you are living in the present moment. She said: "Regardless of the precise mechanism, déjà vu is a transient and common experience that lasts only briefly, affecting people of all ages and not considered a pathological condition. "While it remains a puzzle, déjà vu continues to be a fascinating facet of human consciousness." "It is also important to note that déjà vu is not associated with any particular medical or psychological condition. It is usually a brief and transient experience and is considered a normal aspect of human perception and memory." About two-thirds of people in good health experience déjà vu during their lifetime, according to WebMD, though it is more likely to happen to people aged 15 to 25. The website explains: "A familiar sight or sound can trigger the feeling. You may walk into a room in a building you’ve never visited yet feel like you know it intimately." Health.com adds: "People with more education, those who travel a lot and people who can recall their dreams are also more likely to experience déjà vu."

A newly discovered species of beetle that has sex organs shaped like a bottle opener has been named Carlsberg after the beer giant. Many animals face an uncertain future thanks to changes to their habitats. So, when a brand new species is discovered it is an exciting thing for scientists. It allows experts an opportunity to get creative with the name, with some previous examples including a new rainbow fly species named after RuPaul and an ancient egg-laying mammal named after Sir David Attenborough. Now researchers from the University of Copenhagen have discovered six new South American beetle species of the rove beetle genus Loncovilius, one of which caught the eye. Because the insect’s penis was shaped like a bottle opener. The unusual shape led to researchers giving it the very apt name – Loncovilius carlsbergi. Biologist Aslak Kappel Hansen, from the Natural History Museum of Denmark, explained: “This species is characterised, among other things, by the fact that the male’s sexual organ is shaped remarkably like a bottle opener. "Therefore, we thought it is obvious to dedicate this species to the Carlsberg Foundation, which has generously supported independent research for many years. “Their support for various projects, expeditions, or purchase of the scientific instruments at the Natural History Museum of Denmark contributes to the discovery of new species on our planet.” Hansen explained that the beetles’ penises evolve to be differently shaped, allowing them to only reproduce with members of the same species. “As such,” Hansen explained, “they are often the best way to identify a species. That’s why entomologists like us are always quick to examine insect genitalia when describing a species. The unique shape of each species’ genitals ensures that it can only reproduce with the same species”.

Whilst repairing external parts of the International Space Station (ISS) last week, astronauts dropped a toolbag. And it turns out you just need a pair of binoculars to see it. The bag is tiny compared to the ISS, but it's reflective enough that when it catches the Sun's light it reaches 6th magnitude from Earth according to Earthsky. Under very dark skies, some powerful binoculars or a small telescope might allow you to see the toolbag. The bag is moving at almost exactly the same speed as the ISS on the same path and about a minute ahead of it. Over time, however, its distance from the ISS will grow, making it harder to find. Eventually, its orbit will become low enough that it burns up from friction with the outer atmosphere. You can find out if you have the ISS passing overhead here if you want to have a chance of seeing the bag. The ISS can only be seen easily when it's dark on the ground and sunlight is still catching it. It means it's usually best seen when the skies are not fully dark - so around dusk or dawn. Here is what the toolbag looks like from space: Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

A recent study has found that eating strawberries daily could reduce the risk of developing dementia. Researchers at the University of Cincinnati claim that by eating the fruit every day, certain people of middle age could reduce their risk of dementia. The 12-week study published in Nutrients had 30 overweight patients - who had complained of mild cognitive impairment - abstain from eating berries, aside from a daily packet of supplement powder mixed with water and consumed with breakfast. Half of the participants, who were 50 to 65 years old, received a powder that contained the equivalent of one cup of whole strawberries (the standard serving size), whilst the other half received a placebo. Participants' long-term memory, mood, and metabolic health were measured by researchers. The team found that those who had taken the strawberry powder had performed better on a wordlist learning test, as well as having a significant reduction in depressive symptoms. "Both strawberries and blueberries contain antioxidants called anthocyanins, which have been implicated in a variety of berry health benefits such as metabolic and cognitive enhancements," said Robert Krikorian, professor emeritus in the UC College of Medicine's Department of Psychiatry and Behavioural Neuroscience. "There is epidemiological data suggesting that people who consume strawberries or blueberries regularly have a slower rate of cognitive decline with ageing." Ellagitannins and ellagic acid are also found in strawberries, which are known to possess anti-inflammatory, antioxidant, antimicrobial, and anticancer properties. Krikorian went on to explain that strawberries may have improved cognitive function by reducing inflammation in the brain. "Executive abilities begin to decline in midlife and excess abdominal fat, as in insulin resistance and obesity, will tend to increase inflammation, including in the brain," he explained. The university did, however, acknowledge that Krikorian's research was partly funded by the California Strawberry Commission. Although said that the group had no role in the design of the study, data collection and analysis, or publication of the results.

Google Earth has brought attention to some of the weirdest things we’ve ever seen on the internet – and that’s really saying something. But at times, it really helps to shine a light on truly awe inspiring places that most people would otherwise never even hear about. That’s certainly the case with Vostok island, which people on the internet have been focusing on recently. The uninhabited island is found in the Pacific Ocean and it’s become the subject of much speculation over recent times. But why are people suddenly obsessed with this random island in the middle of nowhere? Well, it’s because the way it’s presented on Google Earth, it looks like the island is “hollow”. Taking an initial look on there, it does look like the island could contain a deep lake or another unusual landform. However, it’s pretty common for areas to be blocked out on Google Earth for a number of reasons. Sometimes, the site just doesn’t have access to different places, or people have requested places to be removed. In the years since it first appeared on Google Earth, there have been all kinds of conspiracies surrounding the Island. Over more recent times, though, it’s become more and more clear that there’s nothing that mysterious about Vostok – and no, it’s not hollow. In fact, it’s part of the Republic of Kiribati, and it’s a remote haven for nature lovers. It’s still a relatively obscure island, given its location, but one National Geographic video does show a diver discussing the idyllic conditions among the island’s coral reefs. Strange things do, though, continue to fascinate people on Google Earth. From mysterious "pyramids” in Antarctica to a "UFO" near the home of Harry and Meghan, there's plenty for conspiracy theorists to get excited about.

An ancient egg-laying mammal named after Sir David Attenborough that was thought to be extinct is actually alive and well, scientists have proved. Attenborough’s long-beaked echidna, which is thought to have been around since the dinosaur era, was caught on camera by an Oxford University expedition to Indonesia. The spiky, furry, beaked creature has been described as a “living fossil” because of how long it has been walking the Earth, about 200m years. Until the video, scientists had relied on a dead, decades-old museum specimen of the creature, as evidence that it was still around. Dr James Kempton, who led the expedition, said: “I was euphoric, the whole team was euphoric.” “I’m not joking when I say it came down to the very last SD card that we looked at, from the very last camera that we collected, on the very last day of our expedition.” Dr Kempton said he had been in touch with Attenborough about the rediscovery, and that the broadcaster was “absolutely delighted”. The expedition also discovered new species of insects and frogs on the trip, which took them through previously unexplored stretches of the Cyclops Mountains, a steep, high-altitude area of Papau, Indonesia. Scientists were twice affected by earthquakes over the course of their expedition, and had to climb narrow ridges with cliffs either side, often in heavy rain. Dr Kempton added: “You're slipping all over the place. You're being scratched and cut. There are venomous animals around you, deadly snakes like the death adder. “There are leeches literally everywhere. The leeches are not only on the floor, but these leeches climb trees, they hang off the trees and then drop on you to suck your blood.” He said he hopes the rediscovery will help promote conservation efforts in the Cyclops Mountains. The species is not currently protected in Indonesia, and scientists don’t know how many there are. “Given so much of that rainforest hasn't been explored, what else is out there that we haven't yet discovered? The Attenborough long-beaked echidna is a symbol of what we need to protect - to ensure we can discover it.” How to join the indy100's free WhatsApp channel Sign up to our free indy100 weekly newsletter Have your say in our news democracy.
