1 . As the COVID-19 pandemic continues, healthcare workers continue to risk their lives to treat patients. Under the current system, diagnosing, monitoring, and managing COVID-19 are contributing to its spread through contact. In an effort to improve this situation, data analytics company SDG Group has announced a new smartphone application called Docdot to help doctors collect relevant clinical data through telemonitoring.
Docdot uses facial recognition technology on smartphone cameras to detect a patient’s vita signs and process them using artificial intelligence. This recognition and processing technology (photoplethysmography) was developed by Binah. ai. It enables smartphone cameras to use the light reflected by blood vessels (血管) under the skin to detect and record changes in the volume of blood flowing in blood vessels under the skin, and that occur due to variations in respiration (呼 吸), blood pressure, etc. The app converts this into measurements reportedly 90 percent as accurate as hospital-grade monitors.
Docdot enables people to look into their smartphone’s screen and share early indicators of infection .It gives health workers the information they need to triage (分诊) patients at a safe distance, preventing unnecessary visits to hospitals and reducing the risk of exposure among health workers and patients. This maximizes the availability of healthcare resources for those who need them most, and contributes to slowing the spread of the virus.
“Use of this technology for virus monitoring and detection is new,” says Heather Beardmore, SDG Group UK chief executive. “This healthcare innovation is the first remote-monitoring and triage tool with potential to transform diagnosis and management.” It is also recognized by World Health Organization (WHO) and Forbes as being one of the most innovative digital health solutions worldwide. Docdot has undergone clinical trials in Canada India and Japan, and is now used in the USA hospitals.

2 . It is generally acknowledged that the older we get, the more slowly we react. However, the new findings suggest that mental speed — the speed at which we can deal with issues requiring rapid decision-making — does not change substantially over decades.
Under the leadership of Dr Mischa von Krause and Dr Stefan Radev, psychologists at Heidelberg University evaluated data from a large-scale online experiment with over a million participants. They came to the conclusion that the speed of cognitive information processing remains largely stable between the ages of 20 and 60, and only deteriorates at higher ages.
In the online experiment, subjects had to press a button to sort pictures of people into the categories “white” or “black” and words into the categories “good” or “bad”. According to Dr Mischa von Krause, the content focus was of minor importance. Instead, the researchers used the large number of data as an example of a response-time task to measure the duration of cognitive decisions.
When evaluating the data, Dr Mischa von Krause and his colleagues noted that, on average, the response time of the test subjects rose with increasing age. However, with the aid of a mathematical model, they were able to show that this phenomenon was not due to changes in mental speed. They think that older test subjects are slower mainly because they reply more cautiously and concentrate more on avoiding mistakes. At the same time, motor function speed slows down during the course of adult life: older participants in the experiment needed longer to press the appropriate key after they had found the right answer.
Another finding of the study was that average information processing speed only progressively declined with participants over the age of 60. “It looks as though, in the course of our life, we don’t need to fear any substantial losses of mental speed — particularly not in the course of a typical working life,” says Dr Mischa von Krause.

3 . One day, Vinod Menon, the head of the physics department at the City College of New York, who had to face the unpleasant task of going through almost a year of COVID-lockdown office mail, opened a 9-month-old package, only to find it contained $180,000.
Piled notes in 50s and 100s wrapped in paper bands, a letter, and a return address to an alias were all that accompanied the parcel addressed to “Head of the Physics Department.” “I’ve never seen this kind of money in real life in cash form except in movies,” Menon told CNN. “That really floored me, so I just did not know how to react.”
The sender evidently had unshakable faith in the US postal system, and desired to send the cash to poor students looking to pursue physics and other sciences. City College of New York is one of the most-productive public university systems, and the physics department is particularly outstanding. Three Nobelists in physics received their education there, and in 1921 Albert Einstein gave one of his first lectures at the campus.
“Assuming that you are a bit curious as to why I am doing this, the reason is straightforward,” the letter read, continuing to explain that its writer had, many years ago, taken advantage of the “excellent educational opportunity” available at City College to study physics, earn a master’s, and pursue a “long, productive, rewarding scientific career.”
The alias return address was to Kyle Paisley, a name absent from the university’s graduation logs, at a house in Pensacola, Florida, whose owners apparently had no idea of the donation. After a two-month long investigation revealing nothing linking the money to criminal activity, the Board of Trustees held a vote and decided to keep the money. Dr Menon noted that the gift would provide for two fully-funded scholarships every year for a decade.

4 . The 2022 Olympic Winter Games have come to an end but the legacy of this showcase event that took place over two glorious weeks will last a lifetime.
Chloe Kim wins in the snowboard halfpipe
USA snowboard star Chloe Kim entered Beijing 2022 as the youngest athlete ever to have won snowboard Olympic gold after claiming the halfpipe title at Pyenong Chang 2018. Kim scored 94.00 points on her very first run to take the gold on February 10.
Arianna Fontana becomes Italy’s most decorated Winter Olympian
Italy’s short track star Arianna Fontana began her Beijing 2022 campaign needing two medals to equal the record as the most-decorated Italian Winter Olympian of all time. Not only did she do that, but she also surpassed the mark with a silver in the 1500 m that put her in a league all of her own with 11 Winter Olympic medals.
Su Yiming thrills the hosts in men’s snowboard big air
The Winter Olympic hosts had something special to celebrate when Su Yiming won the first-ever snowboard gold medal for China. A pair of huge 1800s in his first two runs was enough to see the 17-year-old (now 18) beat off competition from seasoned competitors and take his place at the top of the Olympic podium.
Ireen Wust makes history in Olympic Winter Games
Qualifying for one Olympics is a big feat, but speed skater Ireen Wust of the Netherlands has won an individual gold medal at five different Olympics, becoming the first athlete in history to do so. The 36-year-old attended her first Olympics in 2006. Since then, she has 13 medals, six being gold.

5 . Nowadays, a multilingual voice app helping Indians shop online. India is a country where 1.3 billion people speak 22 officially recognized languages and hundreds of dialects, communication can be a problem online. Despite the number of Indian internet users who don’t speak English as a first language is large, 60% won’t buy online due to language barriers, according to a 2017 report.
Niki, a voice-enabled e-commerce platform, is trying to solve this, providing a virtual assistant that lets people use voice commands to do their shopping, pay utility bills and users speak to the app in their preferred languages, getting products or services.
The company’s target market is people who don’t live in cities and do not speak English in the northern Indiana states. It is planning to introduce seven more languages and hopes to carry out its business in 10 more states.
Thanks to a machine learning algorithm, Nikiis able to understand variations and dialects within a language with increasing accuracy. When the app first appeared, it had a 65% accuracy rate. Now with a bank of 250 million conversations, Niki can process voice commands with 95% accuracy, he says.
The app differs from typical online marketplaces. It limits the number of buying choices. Rather than offering many similar products as the supermarkets do, Niki presents a few quality-controlled objects from providers. That is more like a local store.

6 . The sun is setting, brightening your kids’ faces as they play in the waves. You reach for your phone for this perfect moment. But before you do, here’s a bit of surprising science: Taking photos is not the perfect way to keep memory as you think.
Taking too many pictures could actually harm the brain’s ability to keep memories, says Elizabeth Loftus, a psychology professor at the University of California. So we get the photo but kind of lose the memory.
Photography “outsources” memories. It works in two ways: We either shake off the responsibility of remembering moments when taking pictures, or we’re so distracted by the process that we miss the moment altogether.
The first explanation is the loss of memory. People know that their camera is recording that moment, so they don’t try to remember. The other is distraction. We’re distracted by the process of taking a photo-how we hold our phone, composing the photo, such as smiling faces, the background to our liking and clear image, all of which uses up our attention that could otherwise help us memorize.
However, taking photos can help memory when done mindfully. While taking a photo may be distracting, the act of preparation by focusing on visual details around has the opposite. When people take the time to take clear pictures, memories become strengthened.
Another advantage is that we recall moments more exactly with the photos. Memory has been reshaped with the help of new information and new experiences. Thus, photos or videos help us recall moments as if they really happened.
Memories die away without a visual record backing them up. Therefore, a photo is an excellent tool to help remember when done purposefully, which is worth exploring further.

8 . Attitude actually is mental energy and from the moment you awake in the morning until you fall asleep at night, you are continuously producing this mental energy, or attitude. There is never a time when you can have a neutral attitude. Your attitude right now is either positive or negative.
Your attitude determines your altitude. For example, as a plane is in the air, it has an altitude indicator. The indicator tells the pilot in which direction the plane is going, up or down. Just like the plane, you too have an altitude indicator and you’re the pilot of your plane. The feeling that you gain when something is wrong or what you are doing is not right serves as your altitude indicator. We all have an attitude to our thinking which determines our destiny.
In fact, attitude is a matter of choice. It determines the size of our dreams and influences our determination when we face new challenges and the thing is, no one can control your attitude but you. No one can make us angry. We make ourselves angry when we give in to that control of our attitude and when people do things to anger us. All it does is put our attitude to the tests. We have that choice every morning of what kind of attitude we are going to have for the rest of the day.
Attitude is everything. To begin with every problem is an adventure. To fall, rise and try again is what we call adventure and that’s the real fun of life. Failure is not a bad thing but another chance for success. Dreaming of becoming successful is not enough. There’ ll be a lot of things you hate doing, but you have to do them all and that’s a success.
With a positive attitude, you’ll have the ability to be happier every day, make others around you happier, and live a good life.
