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".

With 88 percent of Indian travellers indicating that they would be more likely to choose a specific accommodation that implements sustainable practices, it rewards and encourages providers to take the next steps on their individual sustainability journeys. "Building a truly sustainable travel industry will take time, coordination, and concerted effort," said Marianne Gybels, Director of Sustainability at Booking.com. "However, progress is possible through continued innovation, partner support, and industry collaboration."
"We are recognising the sustainability efforts of a broader range of properties globally in a credible and transparent manner for consumers." Displaying the practices they have in place allows everyone to make a more informed and hopefully more sustainable decision for their next trip, no matter where they want to go.

South Korean game developer has introduced a new initiative for Battlegrounds Mobile India (BGMI) which will enable a new level of parental control via time limitations and OTP confirmation. The 'Game Responsibly' initiative will also show warning messages along with break reminders, game limits and more. "Every player, below the age of 18, needs to register a parent or a guardian before they start playing for the first time. An OTP will be sent to the registered person's number, post which the minor is allowed to play the game," the company said in a statement.
Some games can get intense and make players lose track of time. However, with timely break-time reminders, the developer has made sure players get the required downtime. These reminders will help them look up from their game and get back to real life, maintaining a healthy game-life balance. In addition, with a strict gameplay limit in place players below 18 years must not indulge in gaming for more than 3 hours per day. This automatically helps them treat gaming as an activity performed in moderation.
The brand has also set an in-game daily spend limit of Rs 7,000 that automatically stops them from overspending and overgaming. Krafton recently announced that it has removed 25 lakh accounts in just over a month to eradicate cheating on Battlegrounds Mobile India (BGMI). Since the last announcement, between October 1 and November 10, Krafton banned 25,19,692 accounts permanently and 7,06,319 temporarily. "The company has cleaned out most of the cheaters in the game, making BGMI a much more fun experience, and will continue to take whatever step is necessary to keep BGMI fair and fun," it claimed.
