Did you know that some people cannot draw a mental picture because they have a recently-characterized condition that causes a lack of visual memory? A new study has examined how this rare condition called aphantasia causes blind spots in the mind’s eye. In fact, the phrase “mind’s eye” may be meaningless to aphantasic individuals, suggests the study published in the journal Cortex.
This condition can be congenital or acquired through trauma. “Some individuals with aphantasia have reported that they don’t understand what it means to ‘count sheep’ before going to bed,” said Wilma Bainbridge, Assistant Professor at the University of Chicago in the US.

“They thought it was merely an expression and had never realized until adulthood that other people could actually visualize sheep without seeing them.” Bainbridge, who is an expert on the neuroscience of perception and memory, decided to experimentally quantify the differences between aphantasic individuals and those with typical imagery on a specific set of visual memory tasks.
The goal was to better characterize aphantasia, which is little-studied and tease apart differences between object and spatial memory. For the study, Bainbridge and colleagues showed photographs of three rooms to dozens of individuals with both typical and limited imagery. They then asked the participants in both groups to draw the rooms, once from memory and once while looking at the photo as a reference.
The differences in the memory experiment were striking: Individuals with typical imagery usually drew the most salient objects in the room with a moderate amount of detail, like color and key design elements — a green carpet, rather than a rectangle. Individuals with aphantasia had a harder time — they could place a few objects in the room, but their drawings were often simpler and relied at times on written descriptions on.
For example, some wrote the word “window” inside an outline of a window rather than drawing the windowpanes.
While people with aphantasia lack visual imagery, they appear to have intact spatial memory, which is distinct from imagery and may be stored differently, according to Bainbridge. People who are congenitally blind, for example, can still describe the layout of a familiar room. As such, individuals with aphantasia were able to place the objects that they did remember in the correct location within a room most of the time, just like those with typical imagery, even though they couldn’t remember many details.

And surprisingly, even though people with aphantasia remembered fewer objects overall, they also made fewer mistakes, said the study. Recognition is also not affected: People with aphantasia knew which pictures of rooms they had already seen when shown them a second time, and also recognize family and friends — though they cannot visualize their faces without seeing them.
Aphantasia has only come to light recently as a psychological phenomenon. Since aphantasia affects only a small percentage of the population, the researchers recruited participants from online forums where people with the condition have shared their experiences to ensure a large sample size of 61 aphantasic individuals and 52 controls with typical imagery. The drawings of both groups were scored objectively by almost 2,800 online volunteers. (IANS)
Just three minutes of exposure to deep red light once a week, when delivered in the morning, can significantly improve declining eyesight, finds a new study. The study, published in the journal Scientific Reports, found there was, on average, a 17 per cent improvement in participants' colour contrast vision when exposed to three minutes of 670 nanometre (long wavelength) deep red light in the morning and the effects of this single exposure lasted for at least a week.
However, when the same test was conducted in the afternoon, no improvement was seen. "We demonstrate that one single exposure to long wave deep red light in the morning can significantly improve declining vision, which is a major health and wellbeing issue, affecting millions of people globally," said lead author, Glen Jeffery from the University College London.

For the study, the team involved a small yet significant number of participants aged between 34 and 70, had no ocular disease, completed a questionnaire regarding eye health prior to testing, and had normal colour vision (cone function). This was assessed using a 'Chroma Test' -- identifying coloured letters that had very low contrast and appeared increasingly blurred, a process called colour contrast.
Using a provided LED device, all participants were exposed to three minutes of 670nm deep red light in the morning between 8 a.m. and 9 a.m. Their colour vision was then tested again three hours post exposure and 10 of the participants were also tested one week post exposure. On average there was a 'significant' 17 per cent improvement in colour vision, which lasted a week in tested participants; in some older participants, there was a 20 per cent improvement, also lasting a week.
A few months on from the first test (ensuring any positive effects of the deep red light had been 'washed out') few participants, carried out the same test in the afternoon, between 12 p.m. to 1 p.m. When participants then had their colour vision tested again, it showed zero improvement.

As the world reopens after 18-20 months of the Covid-19 pandemic and lockdowns, a new variant of the coronavirus -- called B.1.1.529 -- has been identified in South Africa that has left the scientific community worried, as they fear that this new strain could fuel outbreaks in several countries and cripple health systems once again. Over 100 cases have been detected in South Africa, where the new strain is slowly becoming the dominant one.
Here are five things you should know about this deadly super Covid variant that has forced a number of countries, including the UK, Israel, Italy and Singapore, to restrict travel from South Africa and other countries in the region.
1. According to South African health officials, the 'B.1.1.529' variant has many more mutations than scientists expected, especially after a severe third wave, which was driven by the Delta variant. Many of the mutations are of concern for immune evasion and transmissibility.
2. B.1.1.529 carries a high number of mutations in its spike protein, which plays a key role in the virus' entry into cells in the human body. The B.1.1.529 variant has 50 mutations overall, including more than 30 on the spike protein alone which is the target of most current Covid vaccines.

3. The World Health Organisation (WHO) has said it will take a few weeks to understand the impact of the new variant. Scientists have said it is the most heavily mutated version yet, which means vaccines, which were designed using the original strain from Wuhan in China, may not be as effective. The WHO has called a meeting to discuss B.1.1.529 and decide if it will be officially designated a variant of concern.
4. First identified in South Africa this week, the strain has spread to nearby countries, including Botswana. Israel has identified a case of a Covid-19 variant with a large number of mutations "in a person who returned from Malawi". Two cases have been detected in Hong Kong. India has called for rigorous screening of passengers from South Africa, Botswana, and Hong Kong.
5. There are still speculations floating around the variant's origin. According to Francois Balloux, Director of the London-based UCL Genetics Institute, the new strain "likely evolved during a chronic infection of an immuno-compromised person, possibly in an untreated HIV/AIDS patient".

Many industries have been shut down to the global covid-19 pandemic; betting is one of the most affected industries.
By August of last year, most betting shops were closed due to the lockdown issued by the government worldwide. It was announced recently that the pre-tax profits fell by 91% and the betting operators are facing great struggles due to this pandemic.

One of the great things betting industries have accomplished during this pandemic is changing betting from land-based to digital wagering. Online betting has offered better odds and features to the modern bettor and has given betting industries good profits. How does this affect betting shops? Will they stand a chance is of surviving during this pandemic? Should they give way to online betting to take over?
You have to check on online betting websites and windows of land-based bettors to understand how much they depend on professional sporting events. Sports like football, tennis, horse racing, golf, cricket, basketball, dart, and baseball stopped due to covid-19, thus greatly affecting the income of betting.
Brick and Mortar casinos are also remained closed due to this pandemic and it's also not easy to being back bettors to a land-based casino because of all the regulations that have to be followed. The online casino did not greatly suffer during this pandemic compared to the land-based casino. They saw an increase since most bettors used online casinos. To understand how massive the online betting industry has become, Wetten.com explains more. But the question is, what is the future of the betting industry post-covid-19?
The future looks bright in sports betting; some major events such as the PGA tour and English premier league have resumed despite the outbreak of covid-19. The events are taking place, although the fans are not allowed inside the venue; they have allowed online and offline bookmakers to accept bets.
There is a possibility of a second outbreak of this pandemic. So the betting industry should be ready for anything because there is a possibility of sports events being discontinued in the future. It is worth introducing casino games and eSports to online bookmakers that don't offer these services. It's a good time for land-based bookmakers to offer online sports betting as they can be asked to close again in the future.

Online casinos have the chance to operate despite the lockdown situation. But they can also suffer a loss since most people are out of work and can't spend their money on entertainment. Betting is always resilient, even in worse financial status, but there is no assurance that the trend continues since the world is dealing with something that has never occurred before.
The betting industry, just like any other great industry, must consider taking things step by step. Hopefully, things will get back to normal if the pandemic improves. Still, if it is the opposite, online betting websites must be ready with other alternatives for sports betting, just like casino games.
How can betting shops stay in business?
There are two things betting operators have to do to stay afloat. The first one is changing into the digital side, for that is the only option they have. Despite them changing to the digital side, they also have to find ways to help their customers switch over to mobile betting.
Operators should also create an exclusive privilege for VIP players by sectioning their shops where the VIP players can sit and enjoy extra perks. By practicing these two things, the chances of survival for the betting industry will increase.
Practices to use to maintain the betting shops.
Change the payment methods by avoiding cash, instead let the clients use banking methods, credit cards and PayPal to reduce contact with clients.
Make sure players have a proper social distance.
Ensure players spend time in one sector, and this is possible by offering games that don't require movement within the building.
Always decontaminate the building.
How will Virtual Reality Technology help the betting industry?
Gaming machines are the best to make sure that your betting business success. Terminals used in the Virtual Reality Tech allow players to enjoy slots and virtual sports using the same machine. Players feel more secure being able to bet on every game on the same device. With one machine only being used, it reduces contamination since the machine will be contaminated between players.
It's been a whole year since the pandemic began and though it's not over yet, things will get back to normal. The betting industry is not a stranger to the problems caused by the pandemic. The online betting industry is still operating and has also grown, but the retail sector has gone through economic losses. The retail sector can survive the pandemic by following the above measures.
