    ایک تازہ ترین تحقیق میں خبردار کیا گیا ہے کہ پروٹین سے بھرپور غذائیں (بالخصوص وہ جن سے روزانہ 22 فی صد سے زیادہ کیلوریز ملتی ہوں) ایتھروسلیروسِس یا شریانوں کے اکڑ جانے کا سبب بن سکتی ہیں جس سے قلبی مسائل کا سامنا کرنا پڑ سکتا ہے۔

     

    جانوروں اور چھوٹے پیمانے پر انسانوں پر کیے جانے والے ٹرائلز میں یونیورسٹی آف پٹسبرگ کے محققین کو معلوم ہوا کہ پروٹین کی کھپت میں زیادتی (بالخصوص امائنو ایسڈ لیوسن جو کہ گوشت اور انڈوں میں پائے جاتے ہیں، میکرو فیجز میں ایم ٹی او آر سگنلنگ کا سبب بنتے ہیں) اور اہم مدافعتی خلیے شریانوں میں مواد کے جمع ہونے کا سبب بنتے ہیں۔

    جرنل نیچر میٹابولزم میں شائع ہونے والی تحقیق میں سربراہ مصنف ڈاکٹر بابک رازانی نے بتایا کہ ایسے غذائیں کھانا جو پروٹین کا تقریباً 22 فی صد کلوکیلوریز رکھتے ہیں، یہ وہ حد ہے جس پر پروٹین اور اس کے لیوسن خطرات بڑھا دیتے ہیں۔

    ماہرِ امراضِ قلب ڈاکٹر اسٹیفن ٹینگ (جو اس تحقیق میں شامل نہیں تھے) کا کہنا تھا کہ یہ تحقیق کوئی نتیجہ اخذ کرنے کے لیے بہت چھوٹی ہے۔ پھر بھی انہوں نے اس بات سے اتفاق کیا کہ تحقیق اس بات کی جانب اشارہ کرتی ہے کہ ماہرینِ قلب کی پودوں پر مبنی غذاؤں کی جانب رغبت بڑھتی جا رہی ہے

    Current scientific consensus does not support the idea that sugar substitutes in beverages are effective against cancer. In fact, the research is primarily focused on whether they cause cancer or have other negative health effects, and the findings are complex and sometimes conflicting.
    Here’s a summary of what the major health organizations and research suggest:
    * No strong evidence of causing cancer: Many regulatory bodies, like the FDA, and organizations like Cancer Research UK and the World Cancer Research Fund, generally state that there is no strong evidence that approved artificial sweeteners cause cancer in humans at typical consumption levels.
    * “Possibly carcinogenic”: The International Agency for Research on Cancer (IARC) classified aspartame as “possibly carcinogenic to humans” (Group 2B) in 2023. This classification means there is limited, but not convincing, evidence of cancer in humans, or convincing evidence in experimental animals but not both. It’s not a definitive link and highlights the need for more research.
    * Some studies suggest a link: Some observational studies, like a 2022 study of over 100,000 French adults, have suggested a potential link between higher consumption of artificial sweeteners (particularly aspartame and acesulfame-K) and an increased overall cancer risk, including breast and obesity-related cancers. However, these are observational studies, which means they can show an association but not necessarily a direct cause and effect. Other factors could be at play.
    * Focus on reducing sugar: A more established link is between high sugar consumption (especially from sugar-sweetened beverages) and an increased risk of weight gain and obesity, which in turn is a known risk factor for many cancers. Therefore, the general recommendation from health organizations is to limit sugar-sweetened drinks and prioritize water or unsweetened alternatives.
    * Not a “cure” or “treatment”: There is no evidence whatsoever that sugar substitutes act as a treatment or are “effective against” cancer. Cancer treatment involves specific medical interventions.
    In conclusion, while sugar substitutes are often used to reduce calorie intake and manage weight (which can indirectly impact cancer risk by preventing obesity), there is no scientific basis to claim they are “effective against cancer” in a direct sense. The ongoing research is mainly concerned with their safety and potential long-term effects on human health.

    A significant discovery in maritime archaeology has been announced: the wreck of the Imperial Japanese Navy destroyer Teruzuki has been found on the seafloor of the Pacific Ocean, more than 80 years after it sank during World War II.
    The Teruzuki, an Akizuki-class destroyer, was located on July 12, 2025, by a team aboard the Ocean Exploration Trust’s Exploration Vessel (E/V) Nautilus. The discovery was made in Iron Bottom Sound near the Solomon Islands, an area notorious for the numerous naval vessels and aircraft lost during intense battles between August and December 1942.
    The destroyer was commissioned in 1942 and was designed to defend aircraft carriers from aerial attacks. It was lost in December 1942 after being hit by American torpedoes while transporting supplies to Japanese soldiers on Guadalcanal. While nine sailors were killed, most of the crew, including Rear Admiral Raizō Tanaka, survived the attack.
    The exploration team used advanced seafloor mapping tools and remotely operated vehicles (ROVs) to confirm the identity of the ship. Notably, the discovery of the stern section, severed from the main hull and found over 200 meters away with intact depth charges, has led researchers to revise the long-held theory that the ship sank due to an explosion in its depth charge magazine. Instead, the evidence suggests the American torpedoes were the primary cause of the ship’s demise.
    This finding provides valuable insights into the war and the ship’s final hours, as detailed blueprints and images of Japanese naval vessels were kept secret during the war, making this the first visual examination of the Teruzuki for this generation. The discovery is part of an ongoing multinational mission supported by NOAA Ocean Exploration and various institutions from Japan, Australia, New Zealand, and the USA, which has already documented 12 World War II maritime heritage sites in the area.

    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.

    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.

    To detect thyroid problems, healthcare providers typically use a combination of tests. The most common and often first-line tests are blood tests that measure the levels of certain hormones related to thyroid function.
    Here’s a breakdown of the key tests:
    1. Blood Tests:
    * Thyroid-Stimulating Hormone (TSH): This is usually the first test ordered. TSH is produced by the pituitary gland and tells the thyroid how much thyroid hormone (T3 and T4) to make.
    * High TSH: Often indicates an underactive thyroid (hypothyroidism), meaning your thyroid isn’t producing enough hormone. The pituitary gland is working harder to stimulate it.
    * Low TSH: Usually indicates an overactive thyroid (hyperthyroidism), meaning your thyroid is making too much hormone, so the pituitary slows down TSH production.
    * T4 (Thyroxine) and Free T4 (FT4): T4 is one of the main hormones produced by the thyroid.
    * High T4/FT4: Can indicate hyperthyroidism.
    * Low T4/FT4: Can indicate hypothyroidism.
    * “Free T4” is often preferred because it measures the active form of the hormone that is not bound to proteins in the blood, giving a more accurate picture.
    * T3 (Triiodothyronine) and Free T3 (FT3): T3 is another main thyroid hormone.
    * High T3/FT3: Often used to diagnose hyperthyroidism, especially in cases where T4 levels might be normal.
    * T3 is generally less helpful for diagnosing hypothyroidism as it’s one of the last hormones to become abnormal in that condition.
    * Thyroid Antibody Tests: These tests look for specific antibodies in your blood that can indicate an autoimmune thyroid disorder, such as:
    * Thyroid Peroxidase Antibodies (TPOAb): Common in Hashimoto’s thyroiditis (a common cause of hypothyroidism).
    * Thyroglobulin Antibodies (TgAb): Also seen in Hashimoto’s.
    * Thyroid-Stimulating Immunoglobulin (TSI): Often present in Graves’ disease (a common cause of hyperthyroidism).
    * Thyroglobulin (Tg) Test: While not a primary diagnostic test for general thyroid function, it’s used to monitor patients with thyroid cancer after treatment.
    * Calcitonin Test: This measures calcitonin, a hormone produced by C-cells in the thyroid. It’s primarily used to screen for or monitor medullary thyroid cancer.
    2. Imaging Tests:
    * Thyroid Ultrasound: Uses sound waves to create images of the thyroid gland. It can help detect nodules (lumps) or goiter (enlargement of the thyroid) and assess their size, shape, and characteristics. It’s often used when nodules are felt during a physical exam.
    * Thyroid Scan (Nuclear Medicine Scan): Involves taking a small amount of radioactive material (usually iodine), which is absorbed by the thyroid. A special camera then takes pictures to show how much is absorbed and where. It can help:
    * Determine the cause of hyperthyroidism.
    * Evaluate thyroid nodules (e.g., whether they are “hot” or “cold” – indicating how active they are).
    * Radioactive Iodine Uptake (RAIU) Test: Often done in conjunction with a thyroid scan. It measures how much radioactive iodine the thyroid gland takes up over a specific period. This helps differentiate between different causes of hyperthyroidism.
    * CT Scans: Less commonly used for initial thyroid detection, but may be used to get a more detailed view of the thyroid and surrounding structures, especially if there are concerns about compression or extension of a mass.
    Initial Approach:
    Typically, a doctor will start with a TSH test. If the TSH level is abnormal, further blood tests (like T4, Free T4, T3, Free T3, and/or antibody tests) will likely be ordered to pinpoint the specific thyroid condition. Imaging tests are usually reserved for specific situations, such as when nodules are suspected or to determine the cause of hyperthyroidism.
    It’s important to consult with a healthcare professional for proper diagnosis and management of any suspected thyroid issues. They will consider your symptoms, medical history, and test results to determine the best course of action.
