أظهرت دراسات حديثة أن الجزيئات التي قد تنشأ من تحلل المنتجات البلاستيكية اليومية، يمكن أن تجعل النحل أكثر عرضة للبكتيريا والفيروسات البلاستيكية الدقيقة التي تنتقل إلى الدماغ وتتداخل مع إدراك النحل، وقد تؤدي إلى موتها. وحسب الدراسة التي نشرت في مجلة “ساينس دايركت” (sciencedirect) أظهرت التجارب أن تناول النحل لهذه المواد البلاستيكية الدقيقة أو استنشاقها قد يُلحق الضرر بأمعائها ويصل إلى أدمغتها، مما يؤثر على ذاكرتها وقدرتها على التعلم، كما قد يؤدي إلى قتلها مباشرة. وأشارت الدراسة أيضا إلى أن الأزهار يمكن أن تصاب بالاختناق بسبب هذه الجسيمات البلاستيكية الدقيقة، مما يدمر عملية التلقيح بكاملها، ويؤدي إلى خسائر اقتصادية فادحة،…
Former Northampton fly-half Hepher has been part of Exeter’s coaching team since Baxter took over as director of rugby in 2009, while Hunter moved to Sandy Park in 2013 after a successful spell as England Under-20s head coach.The pair have been part of the backroom team that helped the Chiefs win two Premiership titles and the 2020 European Champions Cup as they reached six consecutive Premiership finals between 2016 and 2021. But form has dipped in recent seasons and Hepher was removed as head coach on 20 March and tasked with overseeing the backs and attack strategy until the end…
In the end, Canada’s election was as much about the man in the White House as the one who would be prime minister in Ottawa. The margin was thin, but the verdict from Canadians was clear. With President Donald Trump’s tariffs threatening the foundations of their economy, voters wanted Canada’s leader to be the central banker who navigated the global financial crisis and Brexit. Mark Carney, who until Monday evening was not even a member of parliament, is now on track to lead a minority government with a mandate to confront Trump. He has promised a “broad renegotiation of our…
According to the Financial Times, which cites sources “familiar with the matter,” Apple plans to assemble in India all iPhones intended for the US by the end of 2026. The majority of Apple’s iPhones are currently made in China, but Chinese-made products have become a toxic asset for US import.The US government has imposed a 145 percent tariff on goods from China. While smartphones are included in a 90-day reprieve, announced in early April, President Trump has indicated this exclusion is indeed a temporary one. Ready to pay $2,949 for a base storage iPhone 17 Pro Max?Apple’s supposed shifting of…
أكمل الرئيس الأميركي دونالد ترامب 100 يوم في البيت الأبيض منذ إعادة انتخابه وتوليه منصبه، وهي فترة حملت العديد من القرارات على الصعيدين الداخلي والخارجي، مما جعل ترامب في واجهة التفاعلات، خصوصا بين جمهور منصات التواصل الاجتماعي الذي شاركوا بآرائهم مع مرور هذه المدة الأولى من حكمه. وشهدت المنصات ردود فعل واسعة على أداء ترامب خلال 100 يوم خاصة انتقادات لسياساته وتأثيرها السلبي: فقد عبر مغردون عن استيائهم قائلين إن ما بنته أميركا خلال 100 عام في مجالات البحث العلمي والتميز الجامعي، إلى جانب انفتاحها على الأجانب والمهاجرين، بات مهددا بالضياع خلال 100 يوم فقط من رئاسة ترامب. تقييم رائع…
Mohamed Salah’s selfie celebration during Liverpool’s Premier League title-clinching win over Tottenham Hotspur has become an iconic moment.The Egyptian scored the Reds’ fourth goal in Sunday’s 5-1 victory at Anfield and, after celebrating his strike, borrowed a phone from a staff member before taking a photograph of himself and the cheering Liverpool fans behind him.But some have asked could it have been a marketing idea, because the phone Salah used is made by one of Liverpool’s sponsors.”At the beginning of the season I always take selfies with players [who score], so for this one I said ‘OK, I have to…
Meta has a lot at stake in the current FTC lawsuit against it. In theory a negative verdict could result in a company breakup. But CEO Mark Zuckerberg once faced an even bigger existential threat. Back in 2006, his investors and even his employees were pressuring him to sell his two-year-old startup for a quick payoff. Facebook was still a college-based social network, and several companies were interested in buying it. The most serious offer came from Yahoo, which offered a stunning $1 billion. Zuckerberg, though, believed he could grow the company into something worth much more. The pressure was…
تشير دراسات حديثة إلى أن أنظمة الغذاء في العالم تشهد تحولا خطيرا بسبب تغير المناخ، حيث تؤدي ارتفاع درجات الحرارة إلى خلق بيئة مثالية لتكاثر البكتيريا والجراثيم في الإمدادات الغذائية. وكشفت دراسة نشرت في مجلة “إي بيو ميديسين” (eBiomedicine) أن كل ارتفاع في الحرارة بدرجة واحدة تزيد معدل الإصابة بعدوى”السالمونيلا” و”الكامبيلوباكتر” (عدوى العطيفة) وترفع خطر الإصابة بالتسمم الغذائي بنسبة 5%. وتتعدد الآليات التي يجعل فيها تغير المناخ الغذاء أكثر عرضة للتلوث، حيث تسرع موجات الحر الشديد من نمو البكتيريا مثل “السالمونيلا” و”العصوية الشمعية” في الأطعمة، خاصة تلك المخزنة بعد الطهي. كما تؤدي الفيضانات المتكررة إلى تلوث المحاصيل بمياه الصرف الصحي،…
Success in the form of silverware had proved elusive.Liverpool had achieved an impressive 97 points in 2018-2019 and, even though that would have won them the league title in most other seasons, they were pipped to the top-flight crown by a point by Manchester City.The Reds had also been beaten in the League Cup final and Europa League final in 2016, as well as the 2018 Champions League final.However, the work Klopp had done with his players was eventually rewarded when he won the first trophy of his Liverpool reign with a 2-0 victory against Tottenham in the 2019 Champions…
As the US struggles to contain its worst measles outbreak in years, cases have spilled over into Mexico. In an April 25 report, Mexico’s Ministry of Health reported there have been 583 confirmed cases in the country this year, with 560 recorded in the border state of Chihuahua. On April 27, the Chihuahua Health Secretariat pushed the state’s number of confirmed cases even higher, to 713. In comparison, the Pan American Health Organization reported only 7 confirmed cases in the whole of Mexico in 2024.The outbreak in Chihuahua is partly due to its proximity to Texas, which it borders to…
