    The “secret button” you’re referring to on the back of most iPhones is actually a software feature called Back Tap. It was introduced in iOS 14 and allows you to trigger various actions by simply double or triple tapping on the back of your iPhone. It works on iPhones as old as the iPhone 8 and even with most cases.
    Here’s how to use and set up Back Tap:
    How to Set Up Back Tap:
    * Open Settings: Go to the “Settings” app on your iPhone.
    * Navigate to Accessibility: Scroll down and tap on “Accessibility.”
    * Select Touch: Under the “Physical and Motor” section, tap on “Touch.”
    * Find Back Tap: Scroll all the way to the bottom and tap on “Back Tap.”
    * Choose Tap Action: You’ll see two options: “Double Tap” and “Triple Tap.” You can set a different action for each.
    * Select an Action: Choose the action you want to be performed when you double or triple tap. There’s a wide range of options, including:
    * System Actions: Control Center, Notification Center, Home, Lock Screen, Screenshot, Siri, Volume Up/Down, Flashlight, Camera, App Switcher, and more.
    * Accessibility Features: AssistiveTouch, Magnifier, VoiceOver, Reachability, etc.
    * Scroll Gestures: Scroll Up, Scroll Down.
    * Shortcuts: This is where it gets really powerful! You can create custom shortcuts using the Shortcuts app to launch any app, perform specific tasks (like calling a contact, sending a message, playing music, etc.), or even trigger complex automations.
    How to Use Back Tap:
    Once you’ve set it up, simply double-tap or triple-tap firmly on the back of your iPhone. You don’t need to tap on the Apple logo specifically, just anywhere on the back of the device. The iPhone’s internal sensors are sensitive enough to detect the taps even through a case.
    Tips and Considerations:
    * Consistency: The consistency of Back Tap can vary slightly depending on how you tap and your iPhone model. Some users find tapping near the camera module or just below the Apple logo to be most consistent.
    * Accidental Triggers: If you find yourself accidentally triggering Back Tap, consider setting the action you want to use most as a triple tap, as it’s less likely to be activated unintentionally.
    * Shortcuts App: To truly unlock the potential of Back Tap, explore the Shortcuts app. You can create almost any action you can imagine and assign it to a Back Tap gesture.
    * Availability: Back Tap is available on iPhone 8 and later models running iOS 14 or a newer version.
    Back Tap is a very useful and customizable feature that can significantly improve your iPhone experience, especially for quick access to frequently used functions or accessibility features.

    Yes, solar panels generally generate more electricity in strong sunlight. Here’s why:
    * More Photons: Solar panels work by converting light (photons) into electricity through the photovoltaic effect. Stronger sunlight means a higher intensity of light, which translates to more photons hitting the solar cell’s surface. More photons mean more electrons are dislodged from the atoms in the solar cell material, leading to a greater flow of electric current.
    * Direct Relationship: The short-circuit current (a measure of current output) from a solar cell is directly proportional to the light intensity. So, if the sunlight intensity doubles, the current output will also roughly double.
    * Optimal Conditions: Solar panels typically achieve their peak performance under conditions of about 1000 W/m² of sunlight, which is characteristic of clear, sunny days with direct sunlight. This is often referred to as “peak sun hours.”
    However, there are some nuances:
    * Temperature: While strong sunlight provides more photons, it also increases the temperature of the solar panel. Solar panels are actually more efficient in cooler temperatures. Excessive heat can decrease their efficiency, even if the sunlight is intense. Manufacturers specify a “temperature coefficient” which indicates how much power output will drop per degree Celsius above 25°C.
    * Indirect Sunlight: Solar panels can still generate electricity from indirect or diffuse sunlight (e.g., on cloudy days), but their output will be significantly lower (sometimes 10-25% of their peak output) compared to direct sunlight.
    * Angle of Incidence: The angle at which sunlight strikes the panel also plays a crucial role. Panels are most efficient when the sun’s rays hit them perpendicularly. This is why solar panel installations often consider optimal tilt angles and some advanced systems use trackers to follow the sun’s path throughout the day.
    * Panel Quality and Technology: Modern solar panels, especially monocrystalline ones and those with half-cut cell technology, are designed to perform better in lower light conditions and to mitigate the impact of partial shading.
    In summary, for maximum electricity generation, solar panels thrive on strong, direct sunlight, ideally combined with cooler temperatures.

    Here’s a summary:

    🧠 Who are they called — and what does hibakusha mean?

    The survivors of the 1945 Hiroshima and Nagasaki atomic bombings are known by the Japanese term “hibakusha” (被爆者), literally meaning “explosion-affected persons” (The Times, Wikipedia).
    Officially recognized by Japan’s Atomic Bomb Survivors Relief Law, hibakusha include those who were within a few kilometers of the blast, exposed via fallout, or carried in utero at the time (Wikipedia).

    How many are still alive today (August 6, 2025)?

    • As of March 31, 2025, the Japanese Ministry of Health, Labor and Welfare reported 99,130 living hibakusha in Japan (Nippon).
    • This marked the first time the total fell below 100,000, with the average age now 86.13 years (Nippon).
    • Other sources cite slightly higher figures (e.g. ~106,000 in March 2024 or ~100,000 survivors) but the most current and official number is 99,130 as of March 2025 (Nippon).
    • Every year 6,000 to 10,000 hibakusha pass away, so their numbers are rapidly declining (Arms Control Association).

    Summary

    Topic Details
    What they’re called Hibakusha (atomic bomb survivors)
    Still alive ~99,130 as of March 31, 2025
    Average age ~86 years old
    Annual deaths ~6,000–10,000 hibakusha annually

    Why it matters

    • With only ~99,000 survivors left—all elderly—it is increasingly urgent to record their firsthand testimonies while possible.
    • Survivors have long been central to global anti-nuclear advocacy, primarily through Nihon Hidankyo, the Japan Confederation of A‑ and H‑Bomb Sufferers Organizations, which won the 2024 Nobel Peace Prize for its decades‑long peace activism and survivor testimony (El País, Wikipedia, Arms Control Association, Nippon).
    • Some extremely rare individuals are double hibakusha, exposed to both bombs—only two confirmed living survivors remain, such as Ayano Hirashima, who survived both Hiroshima and Nagasaki (The Times).

    In short: about 99,130 hibakusha are still alive in Japan as of March 2025, most aged in their mid‑ to late 80s. Their continued testimonies are vital to preserving memory and advocating against future nuclea

    Before the full-scale invasion of Ukraine in February 2022, Russia was a global energy powerhouse, supplying a significant portion of the world’s oil, natural gas, and coal. Its role as an energy exporter gave it considerable leverage, particularly over Europe.

    Here’s a breakdown of global dependence on Russian oil and gas, and how it has changed:

    Oil Dependence:

    • Before the War: Russia was the world’s second-largest exporter of crude oil after Saudi Arabia. Europe was its primary customer. In 2021, the EU imported about 4.5 million barrels per day (bpd) of oil from Russia, accounting for roughly 34% of its total oil imports. Some individual European countries had even higher dependencies.
    • Post-Invasion & Sanctions (Current as of July 2025): Western sanctions, including the G7 price cap on Russian oil, have dramatically reshaped global oil flows.
      • Europe: The EU has significantly reduced its direct imports of Russian oil. By the end of 2022, official EU imports of Russian oil had fallen by about 90%. However, some Russian oil still reaches Europe via “third countries” after being refined (a “refining loophole”) or through illicit imports. Hungary, for example, remains a significant importer of Russian fossil fuels in the EU.
      • Asia (New Major Buyers): Russia has successfully redirected much of its oil exports to Asian markets, selling at discounted prices.
        • China: Has become Russia’s largest buyer of crude oil, purchasing around 47% of Russia’s crude exports as of June 2025.
        • India: Has emerged as the second-largest purchaser, buying approximately 38% of Russia’s crude exports. Its imports from Russia have skyrocketed since the invasion, now making up over 35% of India’s total oil imports.
        • Turkey: Also increased its imports of Russian oil.
      • Other Regions: Brazil has also increased its imports of Russian oil products. Some Gulf states like Saudi Arabia and the UAE have also increased imports of cheaper Russian fuel oil for domestic power generation or re-export as bunker fuel, freeing up their own crude for more lucrative markets.

    Natural Gas Dependence:

    • Before the War: Europe was overwhelmingly dependent on Russian natural gas, primarily delivered via an extensive network of pipelines. Russia supplied roughly 40% of all imported gas to the EU in 2021, reaching about 142 billion cubic meters (bcm). For some individual countries like Germany, Austria, and Latvia, the reliance was much higher, in some cases exceeding 50% or even 80%.
    • Post-Invasion & Sanctions (Current as of July 2025): This is where the most dramatic shift has occurred, particularly for Europe. Russia significantly cut gas flows to Europe, and the Nord Stream pipelines were sabotaged.
      • Europe: Europe has drastically reduced its direct pipeline gas imports from Russia. The volume fell from 142 bcm in the year before the invasion to just 31 bcm in 2024, and potentially as low as 16-18 bcm in 2025. The transit contract via Ukraine also expired at the end of 2024 and was not renewed, further limiting pipeline routes. The only remaining major pipeline bringing Russian gas to the EU is TurkStream, which primarily supplies countries in Southeast Europe.
      • Replacement Strategies: Europe has rapidly diversified its gas sources by:
        • Increasing imports of Liquefied Natural Gas (LNG), primarily from the US, Qatar, and other producers.
        • Boosting pipeline gas imports from Norway, Azerbaijan, and Algeria.
        • Implementing significant energy conservation measures and accelerating the deployment of renewable energy.
      • Remaining Dependent EU States: While overall EU dependence is down, a few countries, notably Hungary and Slovakia, still maintain significant reliance on Russian gas due to historical infrastructure and specific agreements.
      • China: Russia is actively pursuing new pipeline projects (e.g., Power of Siberia 2) to increase gas exports to China, aiming to offset lost European demand.

    Overall Impact:

    • The Ukraine conflict has forced a major recalibration of global energy markets.
    • Europe has significantly reduced its reliance on Russian fossil fuels, particularly gas, at a considerable economic cost and through massive efforts in diversification and renewables.
    • Asian countries, especially China and India, have stepped in to become the primary buyers of discounted Russian oil, allowing Russia to largely maintain its export volumes despite Western sanctions.
    • The global energy map is becoming more multipolar, with new trade routes and supplier-buyer relationships emerging.
    • However, for many countries, fully divorcing from Russian energy remains a complex and ongoing challenge, highlighting the deep interdependencies that existed before the conflict.

    A recent study published on Medical News Today suggests that eating eggs just once a week may be linked to a reduced risk of developing Alzheimer’s disease.
    The study found that individuals who consumed at least one egg per week had a 47% reduced risk of Alzheimer’s compared to those eating eggs less than once a month. The researchers also observed less buildup of toxic proteins associated with Alzheimer’s in the brains of those who ate eggs more regularly.
    While eggs have been a subject of debate regarding cholesterol and heart disease, current research generally indicates that for most healthy individuals, moderate egg consumption (up to 7 eggs a week) does not significantly increase the risk of heart disease. However, individuals with specific health conditions like diabetes or high cholesterol may need to monitor their intake more closely.
    It’s important to remember that a varied, nutrient-dense diet rich in whole foods is crucial for overall brain health and reducing the risk of various chronic diseases.

    In response to Russia’s invasion of Ukraine, a comprehensive set of sanctions has been imposed on Russian oil and gas by various international actors, primarily the European Union (EU), G7 nations, and Australia. These sanctions aim to significantly reduce Russia’s revenue from energy exports, which fund its war efforts.

    Here’s a breakdown of the key sanctions:

    1. Oil Price Cap:

    • G7 and EU Initiative: The G7 nations, in coordination with the EU and Australia, established a price cap on seaborne Russian crude oil. Initially set at $60 per barrel in December 2022, the EU recently lowered it to $47.60 per barrel as part of its 18th sanctions package (effective September 3, 2025).
    • Mechanism: This cap prevents EU and G7 operators from providing services (such as shipping, insurance, and financing) for the maritime transport of Russian crude oil and refined petroleum products if they are sold above the specified price cap.
    • Dynamic Review: The EU’s latest package also introduced a dynamic review mechanism for the oil price cap, ensuring it remains at a certain percentage (e.g., 15%) below the average market price of Urals crude over a six-month period. This aims to ensure predictability for operators while maintaining downward pressure on Russian revenues.
    • Refined Products: Separate price caps are in place for refined oil products: $100 per barrel for high-value products (like diesel and petrol) and $45 per barrel for low-value products (like fuel oil). These remain unaffected by the recent crude oil price cap adjustment.

    2. Import Bans and Embargoes:

    • EU Seaborne Oil Ban: The EU has prohibited the import of seaborne crude oil and refined petroleum products from Russia. This largely came into effect in December 2022.
    • Coal Ban: The EU has an import ban on all forms of Russian coal.
    • LNG Restrictions:
      • A ban on future investments in, and exports to, liquefied natural gas (LNG) projects under construction in Russia.
      • A ban on the use of EU ports for the transshipment of Russian LNG.
      • A ban on the import of Russian LNG into specific terminals not connected to the EU gas pipeline network.
      • Prohibiting Russian nationals or entities from booking gas storage capacity in EU Member States.
    • Pipeline Oil (Limited Exceptions): While the seaborne ban is extensive, some exceptions for pipeline oil initially existed for certain EU countries heavily reliant on Russian supply. However, Germany and Poland have ended the possibility to import Russian oil by pipeline.
    • Refined Products from Third Countries: A significant new measure in the EU’s latest package is a ban on the import of refined petroleum products made from Russian crude oil and coming from any third country (with exceptions for Canada, Norway, Switzerland, the UK, and the US). This targets countries like India and Turkey that have been refining Russian crude and exporting it to the EU.

    3. Targeting the “Shadow Fleet”:

    • Vessel Sanctions: The EU, G7, and the US have directly sanctioned numerous oil-carrying vessels suspected of involvement in violating the price cap or hiding the origin of Russian oil.
    • Monitoring and Enforcement: Measures have been introduced to monitor the sale of tankers to third countries and pressure flag countries to better check for price cap breaches. The EU has blacklisted over 400 vessels in Russia’s “shadow fleet.”
    • Port Access Prohibition: The EU prohibits access to European ports for vessels suspected of having been involved in transshipment of Russian oil at a price higher than the price cap or having turned off their Automatic Identification System (AIS) trackers.

    4. Technology and Services Bans:

    • Refining Technologies: A ban on exports of specific refining technologies to Russia, making it harder and more costly for Russia to upgrade its oil refineries.
    • Oil and Gas Exploration Software: A ban on the export, supply, or provision of oil and gas exploration software to Russia.
    • U.S. Petroleum Services: The U.S. has prohibited the provision of U.S. petroleum services to persons located in Russia, aiming to cut off Russia’s access to U.S. services related to the extraction and production of crude oil and other petroleum products.

    5. Financial and Business Measures:

    • Investment Ban: A far-reaching ban on new EU investments across the Russian energy sector, with limited exceptions for civil nuclear energy and the transport of certain energy products back to the EU.
    • Banking Restrictions: Sanctions on Russia’s banking sector to limit Moscow’s ability to raise capital and carry out international transactions.
    • Nord Stream Pipelines: A ban on future transactions via both Nord Stream pipelines, which are currently non-operational.

    Impact: These sanctions have had a significant impact on Russia’s energy revenues, forcing Russia to seek new markets, often selling oil at discounted prices. They have also led to the growth of a “shadow fleet” and complex supply chains to circumvent restrictions. While challenging to enforce completely, the sanctions aim to continue squeezing Russia’s financial resources for the war.
