  A rare computer mouse, which inspired Steve Jobs to create Apple's first mouse, has been sold at an auction in New York for a whopping $178,936. The mouse and coding key set were made by computing legend Douglas Engelbart, the founder of the controller system, over 55 years ago. This rare mouse has three buttons and uses two metal discs to track the cursor's position, which was later replaced by a ball or optical light. The coding key set consists of five keys, allowing 31 key press combinations to type commands. Apple founder Steve Jobs bought Engelbart's patent for $40,000 after seeing this invention, and it took off, selling in the billions. In December 2020, the first prototype of the mouse was auctioned for $34,000, and in March 2022, another mouse and coding set by Engelbart sold for $46,000. Over time, the computer mouse has continued to improve and today it is in its most advanced form. The sale of this rare mouse at the auction highlights its historical s

  The desire to explore and settle on the moon has been a long-standing dream of humanity since man first stepped on the lunar surface. Now, the UK government has started official preparations towards making this dream a reality. The British space agency is making important progress towards building a nuclear reactor that will ensure human habitation on the moon. To achieve this historic project, Rolls Royce has been given a significant investment of 2.9 million dollars by the agency. Last year, the British space agency conducted research to build a nuclear reactor, which was successful and paved the way for progress towards the completion of the project. The British Minister of Science has expressed his opinion that this project is another testament to Britain's scientific prowess. Rolls-Royce engineers and scientists will use the microreactor to test how nuclear energy can be used to build a permanent base and human settlement on the moon. The company is aiming to produce t

  The Indian Council of Medical Research (ICMR) has issued a warning regarding the rapid spread of adenovirus, including liver cancer and scarlet fever in India. Influenza A subtype H3N2 is currently spreading rapidly in the country and has become a major cause of sickness among people. ICMR stated that 50% of patients undergoing treatment in hospitals were infected with this virus. Moreover, 92% of those infected with the virus have a fever, 86% have a cough, 27% have difficulty breathing, and 16% have chest tightness. About 16% of those infected experienced symptoms of pneumonia, and 6% had asthma attacks. Symptoms of H3N2 include cough, nausea, vomiting, sore throat, fever, and body ache, and fever can last for up to three days while coughing may persist for three weeks. Medical authorities in India recommend that people suffering from this virus do not need antibiotics. Instead, they should be treated with basic care as the use of antibiotics can lead to resistance. Medical

  Feelings of sadness, despair, and disgust are common human emotions that typically last for a week or two. However, when these symptoms persist for longer, it is referred to as depression, which is a disease like high blood pressure and diabetes that can affect anyone. Unfortunately, there is a common misunderstanding surrounding depression, with some people failing to recognize it as a disease. Depression is primarily related to psychological problems, and anxiety is often a significant component of it. However, psychologists have pointed out that anxiety can have benefits. In an article by Dr. and Psychologist David Rosemary published on "Be Psychology Today," he explained that stress resulting from anxiety can strengthen emotional relationships and restore love relationships. Stress can also improve a person's connection with others. Psychologists suggest that anxiety is not necessarily bad, and experiencing it can help enhance essential skills for building rel

  Japan has announced plans to launch a drone-powered postal system, marking a significant shift in the use of drones from military to philanthropic purposes. Despite being associated with fear worldwide, drones are set to play a vital role in delivering long-distance mail across Japan. The postal department, Japan Post, has completed all necessary preparations for the drone-powered system but is awaiting government approval to proceed. The officials are optimistic that the Model K drone, developed by ACSL, will receive clearance for delivering Level Four parcels within the next few days. The Japan Post expects that drones will eventually provide delivery services to customers residing in remote and mountainous areas, which are difficult to reach through traditional vehicles. The drone-powered postal system will help overcome the challenges conventional delivery systems face, particularly in remote areas with limited access. This innovative approach will not only improve the efficien

  Back and leg pain are common problems that affect many people, especially those with unhealthy lifestyles. During pregnancy, this type of pain can make things more challenging. Sciatica is a type of pain that follows the sciatic nerve's path from the lower back, through the hips and buttocks and down the leg. It can cause inflammation, pain, and sometimes numbness in the affected leg. Arthritis can also cause pain that spreads from the lower spine to the hips and the back of the leg. You may feel pain anywhere along the nerve pathway, but it's more likely to occur from your lower body to your hips and the back of your thighs and calves. Spinal pain can range from mild to severe and can cause a burning sensation or feel like an electric shock. Prolonged sitting can exacerbate these symptoms. Some people may also experience numbness, tingling, or muscle weakness in the affected leg or foot. Mild pain usually goes away on its own. However, if the pain is severe, it is

  Drinking tea is a common habit for many people, but health experts warn about the potential dangers of drinking tea on an empty stomach. While tea has many benefits, some side effects depend on when and how it is consumed. Dehydration is a common problem when drinking tea on an empty stomach. If you don't eat anything with your tea, you can suffer from dehydration, especially after sleeping through the night. Another potential side effect of drinking tea on an empty stomach is acidification. This can affect the balance of acid, base, and alkaline in your body fluids, leading to acid reflux and heartburn. Drinking tea on an empty stomach can also cause flatulence and indigestion, especially if milk is added. This can lead to constipation and bloating. Finally, daily tea consumption can increase the number of bacteria in the mouth, leading to tooth decay. To avoid this, it's better to include tea in your diet after breakfast. In summary, drinking tea can have many b

  Obesity is a serious medical condition caused by excess body fat that can lead to various health issues. Losing weight is essential for maintaining optimal health and avoiding health complications. For individuals struggling with weight loss, there is a simple yet effective method that can help reduce body weight without any special effort. Adequate sleep is the key to making diet and exercise routines more effective, according to a study conducted by the Tusburgh University in America. The study involved 125 overweight or obese adults who were placed on a one-year weight loss program. The researchers observed the participants' sleep duration and how it affected their ability to maintain a healthy diet and exercise routine. The results showed that those who slept longer were better able to control their dietary calories while incorporating exercise into their daily routine. Adequate sleep not only helped to reduce body weight but also improved overall health and well-bein

  Our daily habits profoundly impact our overall health, including our brain health. Certain bad habits can cause our brains to age prematurely, which can lead to various health issues. Here are some habits that you need to change if you want to keep your brain healthy and prevent premature ageing: 1.       Sedentary lifestyle: If you spend most of your time sitting on the couch and leading a sedentary lifestyle, it can harm your brain health. Regular physical exercise helps to increase blood flow to the brain, which keeps it healthy and active. 2.       Smoking: Smoking is one of the worst habits that harm your lungs and affects your brain health. A study has shown that heavy smokers have twice the risk of developing Alzheimer's disease compared to the general population. 3.       Lack of sleep: Sleep is crucial for our brain health, and getting less than seven to eight hours of sleep per day can cause stress and increase the risk of various health issues. 4.       Unh

  Kidneys are vital organs in the body responsible for filtering waste and excess materials, regulating salt, potassium, and acid levels, controlling blood pressure, and producing red blood cells. Unfortunately, kidney disease is prevalent in India, affecting around 15% of the population, with 8 to 10 thousand people requiring transplants yearly. The causes of kidney failure are numerous, including underlying health conditions such as diabetes, high blood pressure, and heart disease. Uncontrolled diabetes can increase glucose levels, causing rapid blood flow that may damage kidney tissues. Using indigenous medicines without medical advice or suffering from hypertension or stroke can also increase the risk of kidney failure. Diagnosing and treating kidney disease promptly is essential to avoid developing serious complications that could lead to the loss of life. While both kidneys' failure is severe, patients can survive through dialysis or transplantation. In comparison, thes

  A recent pooled analysis conducted by HealthDay Internet has found that consuming less than 2.5 grams of salt per day may increase the risk of death rather than providing benefits. This research is based on the analysis of mortality and hospitalization rates and the assessment of various sodium levels in approximately 3,500 people with heart failure. The study has shown that patients who consume less than 2.5 grams of sodium per day have an 80% higher risk of death than those who consume 2.5 grams or more of sodium per day. Although reducing sodium intake during heart failure treatment is a popular approach, the researchers suggest that the extent of this reduction should be carefully debated. The research has concluded that a moderate and careful reduction in sodium intake is required instead of a drastic reduction. Therefore, it is important to consult a healthcare professional to determine an appropriate sodium intake level that best suits your health needs.

  World Sleep Day: Importance of Restful Sleep for Optimum Performance Today, on the third Friday of March, the world is celebrating World Sleep Day to raise awareness about the importance of restful sleep for our overall well-being. Experts believe that lack of sleep can have a negative impact on our physical and mental health, affecting our performance in various aspects of life. One of the first effects of sleep deprivation is decreased physical energy and mental performance. It can make us feel tired, lethargic, and unable to perform daily tasks effectively. Lack of sleep can also limit our ability to think creatively and generate new ideas. Moreover, prolonged sleep deprivation can lead to obesity, depression, diabetes, and heart disease. Depression is one of the negative effects of sleep deprivation. It can make us irritable and affect our ability to perform daily tasks, leading to depression. Lack of focus is another effect of sleep deprivation, which can later develop i

  Rare Purple Honey Produced Only in North Carolina, USA North Carolina, USA, is home to rare honey not found anywhere else. Its unique feature is purple, which is not typically seen in honey. The reason behind the color is not yet known. This purple honey is produced by bees in the Sands Hill region of North Carolina and is becoming famous among consumers worldwide. However, it is extremely rare and difficult to find. The honey is made up of various components and has a sticky texture. Its color changes when viewed from different angles, and it has a less sweet taste than other honey types. Over the years, experts have analyzed various types of honey and discovered unusual ones, including the expensive and bitter "corbzolo" honey and the matte honey produced by vulture bees. However, none of this honey comes close to resembling the purple honey produced in North Carolina, which is completely genuine and pure. Despite its rarity, this unique honey is gaining popular

  Twitter is planning to launch a 'spin-up subscription' feature that will allow users to earn money through exclusive content, according to Elon Musk, CEO of Tesla and SpaceX. The new feature is expected to be a great opportunity for users to monetize their content and followers on the microblogging platform. Recently, Twitter announced that after March 20, it will no longer allow non-Twitter Blue users to use text messages as a two-factor authentication method. In addition, the company confirmed earlier this month that it will charge a monthly fee for its Bluetick service with web verification and Blue subscribers in the US will be able to tweet up to 4,000 characters.

In a bizarre incident that has left many puzzled, a 65-year-old man in Utah, USA, walked into a Wells Fargo bank in Salt Lake City and attempted to rob the bank but only asked for one dollar. According to police officials, the man handed the teller a handwritten note asking for a dollar, saying, "Please forgive me for doing this, but It's a robbery, give me a dollar, thanks."

Researchers at Northwestern University have developed an electric bandage that has the potential to revolutionize wound healing. Led by Professor Guillermo Amir, the team created an electric strip that, when applied to a wound, can speed up the healing process by up to 30%. The electric strip is designed to be applied easily to a cotton pad and generates a mild electric current when applied to the wound. In addition to promoting faster healing, the strip also has sensors and circuits embedded with microelectronics that transmit information about the wound to an external device, such as a smartphone or tablet. This is especially beneficial for elderly patients and diabetics, who are at a higher risk of developing chronic wounds that can turn into long-lasting canker sores. For diabetics, in particular, the risk of limb amputation due to chronic wounds is a significant concern. With this new technology, patients can receive early notifications about any infections or complication

  TikTok, the popular video-sharing app, has recently introduced a new feature called 'Series,' allowing users to earn extra income from their viral videos. This feature is expected to be a game-changer for content creators looking to monetize their videos on the platform. With Series, eligible users will be able to compile their videos into an album and sell it to their followers for a fee. Each album will consist of up to 80 videos lasting up to 20 minutes. Currently, this feature is available only to a select number of users, but it will be rolled out more widely soon.

TikTok will not take any share of this revenue, but users must pay a fee to be part of the Series. The exact fee charged by TikTok for this service is yet to be disclosed. It is not yet clear how a user will qualify for the Series feature, but according to the company, an application option to

By introducing integrated features, Google is making a strong push for using its Pixel watch in conjunction with smartphones. Recently, the company announced a major update to the Pixel Watch at CES 2023, which includes an option called Watch Unlock. This new feature allows users to unlock their smartphone with a simple gesture of their wrist, much like the Apple Watch's iPhone unlocks option. However, Google officials have stated that the Watch Unlock feature will only work if the fingerprint sensor or Face ID of the smartphone owner is not functioning. This new unlock feature is expected to be compatible with Android 13-based devices, as the new version includes an Active Unlock API that allows the feature to work with connected devices, such as the Pixel Watch. While Google's Smart Lock feature is already highly effective, Watch Unlock allows users to shift some of their security responsibilities to their smartwatch. With this new feature, the Pixel watch is becoming

Have you ever noticed that your computer keyboard's F and J keys have lines on them? These lines are also known as homing bars and serve a specific purpose. They are designed to help touch typists type without looking at the keyboard, using both hands to type quickly and efficiently. When you place your index finger on the F key and your middle finger on the J key, your other fingers should naturally fall into place on the adjacent keys. The lines on the F and J keys help your brain to identify the correct placement of your hands and fingers on the keyboard, allowing you to type more quickly and accurately without looking down. Interestingly, Not all keyboards have homing bars on the F and J keys. Some modern keyboards have replaced them with small raised bumps to indicate hand placement. However, the purpose remains to help touch typists navigate the keyboard without looking down. In conclusion, the lines on the F and J keys of your computer keyboard are homing bars that h
