ڈائنوسارز بھی اسانوں کی طرح کینسر کا شکار ہوتے تھے
جی ہاں، ڈائنوسارز بھی انسانوں کی طرح کینسر کا شکار ہوتے تھے۔ سائنسدانوں نے ڈائنوسارز کی باقیات (فوسلز) میں کینسر کی علامات دریافت کی ہیں۔ یہ اس بات کا ثبوت ہے کہ یہ بیماری لاکھوں سال پہلے بھی موجود تھی اور صرف انسانوں تک محدود نہیں تھی۔ ہڈیوں کے کینسر (جیسے اوسٹیوسارکوما) کے کیسز ڈائنوسارز کی فوسلزاقرأ المزيد
جی ہاں، ڈائنوسارز بھی انسانوں کی طرح کینسر کا شکار ہوتے تھے۔
سائنسدانوں نے ڈائنوسارز کی باقیات (فوسلز) میں کینسر کی علامات دریافت کی ہیں۔ یہ اس بات کا ثبوت ہے کہ یہ بیماری لاکھوں سال پہلے بھی موجود تھی اور صرف انسانوں تک محدود نہیں تھی۔ ہڈیوں کے کینسر (جیسے اوسٹیوسارکوما) کے کیسز ڈائنوسارز کی فوسلز میں پائے گئے ہیں، جو یہ ظاہر کرتے ہیں کہ انہیں بھی ٹیومر اور دیگر کینسر سے متعلقہ بیماریاں ہو سکتی تھیں۔
یہ دریافت ہمیں قدیم زندگی اور بیماریوں کے ارتقاء کے بارے میں مزید سمجھنے میں مدد دیتی ہے۔

Pakistan’s relationship with cryptocurrency is a complex and evolving one, with signs of both significant adoption and ongoing regulatory challenges. The analogy of a “crypto balloon flying too close to the sun” might be apt, given the enthusiasm for crypto in the country juxtaposed with the inherent risks and the government’s cautious, often contradictory, stance.
Here’s a breakdown of the situation:
High Adoption Despite Ambiguity:
The Evolving Regulatory Landscape – A Mixed Signal:
Risks and Challenges (The “Too Close to the Sun” Part):
Conclusion:
Pakistan’s crypto balloon is undoubtedly flying high, fueled by strong public interest and a recognition of the technology’s potential. However, it’s also navigating a turbulent regulatory atmosphere. The “too close to the sun” analogy highlights the inherent risks of this high-flying adoption without a clear, comprehensive, and consistent regulatory framework.
The current move towards regulation, particularly with the establishment of the PDAA and PCC, suggests a more pragmatic approach from the government. If successful, this could help mitigate the risks and allow Pakistan to harness the benefits of digital assets. However, until a robust and unified legal framework is firmly in place, the journey remains fraught with uncertainty for crypto users and businesses in the country.

Plastic bags indeed pose significant urban problems, impacting various aspects of city life and the environment. Here’s a breakdown of the major issues:
قراءة أقل1. Environmental Pollution and Litter:
* Visual Blight: Plastic bags are highly visible litter, accumulating in streets, parks, and waterways, making urban areas look unsightly and neglected.
* Drainage Systems Clogging: They easily get into storm drains and sewer systems, causing blockages that lead to localized flooding during rain events. This can damage infrastructure, disrupt traffic, and create unhygienic conditions.
* Harm to Wildlife: Animals, particularly birds and marine life, often mistake plastic bags for food, leading to ingestion that can cause internal injuries, blockages, starvation, and death. They can also get entangled in bags, hindering movement and causing suffocation.
* Soil and Water Contamination: As plastic bags break down into microplastics over time, they contaminate soil and water sources, potentially entering the food chain and posing risks to human health.
2. Waste Management Challenges:
* Bulky and Lightweight: Despite their light weight, plastic bags take up significant volume in landfills, reducing their lifespan. Their lightweight nature also makes them easily airborne, contributing to litter.
* Difficult to Recycle: Many types of plastic bags are difficult and expensive to recycle due to their low density and tendency to jam recycling machinery. Contamination from food residue or other materials also makes them unsuitable for many recycling processes.
* High Collection Costs: Cleaning up littered plastic bags requires significant municipal resources, including labor and equipment, increasing waste management budgets.
3. Economic Impacts:
* Tourism and Property Values: A polluted urban environment due to plastic bag litter can deter tourism and negatively impact property values, reducing economic opportunities.
* Infrastructure Damage: The costs associated with clearing clogged drains and repairing flood damage caused by plastic bags can be substantial for municipalities.
* Agricultural Impact (Peri-Urban Areas): In areas where urban sprawl meets agricultural land, plastic bags can blow into fields, affecting crop growth and potentially being ingested by livestock.
4. Social and Health Issues:
* Disease Vectors: Clogged drains and standing water caused by plastic bags can create breeding grounds for mosquitoes and other disease-carrying vectors.
* Aesthetic Degradation: A visually polluted environment can negatively impact the mental well-being and sense of pride among urban residents.
Solutions and Mitigation Efforts:
Many cities worldwide are implementing strategies to combat the plastic bag problem, including:
* Bans or Levies: Imposing outright bans or charging fees for plastic bags to discourage their use.
* Promoting Reusable Bags: Encouraging citizens to use cloth or other durable reusable bags.
* Improved Waste Management: Investing in better collection systems, street cleaning, and advanced recycling technologies.
* Public Awareness Campaigns: Educating the public about the environmental impact of plastic bags and the importance of responsible disposal.
* Developing Biodegradable Alternatives: Research and development into truly biodegradable and compostable bag alternatives.
Addressing the plastic bag problem requires a multi-pronged approach involving government policy, industry innovation, and public cooperation.

As of Sunday, June 15, 2025, the tensions between Iran and Israel have escalated significantly, marking the third day of overt conflict. Here’s a summary of what we know:
قراءة أقلInitiation of Conflict:
* Friday, June 13, 2025: Israel launched major airstrikes on Iran, codenamed “Operation Rising Lion.” These attacks targeted Iran’s nuclear facilities, military installations, and reportedly killed several top Iranian military leaders and nuclear scientists, including IRGC commander Hossein Salami and Major General Mohammad Bagheri. Explosions were reported in Tehran and near nuclear sites like Natanz and Esfahan. Israel stated its aim was to “degrade, destroy, and remove the threat” of Iran’s nuclear weapons program.
* Friday, June 13, 2025 (Evening): Iran quickly retaliated with a large-scale attack on Israel, launching over 150 ballistic missiles and more than 100 drones, codenamed “Operation True Promise III.”
Escalation and Continued Strikes:
* Saturday, June 14, 2025: Both sides continued their strikes. Israel expanded its targets to include Iran’s energy industry, while Iranian missile and drone attacks on Israel continued, reportedly hitting cities like Haifa and Tel Aviv.
* Sunday, June 15, 2025: The exchange of strikes has continued for a third day. Israel has unleashed further airstrikes across Iran, threatening greater force. Some Iranian missiles have reportedly evaded Israeli air defenses and struck buildings in central Israel. Iran’s Revolutionary Guard Corps (IRGC) claimed to have targeted Israel’s fuel infrastructure in response to Israeli strikes on its oil facilities.
Casualties and Damages:
* Iran: Iranian media has reported significant casualties, with unofficial tolls on Saturday stating 78 people killed and 329 injured in Tehran alone. Al Jazeera reports at least 80 people killed and 800 wounded across Iran over the past two days, including 20 children and nine nuclear scientists. Israeli strikes have caused fires at oil storage facilities in Tehran and other areas.
* Israel: Iran’s retaliatory strikes have also caused casualties. Israel’s Magen David Adom rescue service reported at least 10 people killed overnight and into Sunday, bringing Israel’s total death toll to 13. Reports indicate strikes hitting residential areas, with one attack in Bat Yam (a Tel Aviv suburb) killing at least six people, including two children, and wounding 180.
International Reaction:
* The United Nations Security Council held a meeting on Friday, June 13, to discuss the rising tensions.
* Calls for de-escalation are mounting from world leaders.
* The conflict has closed Israel’s main international airport and airspace for a third day.
Context and Broader Implications:
* This direct military confrontation marks a significant escalation in the long-standing “shadow war” between Israel and Iran, which previously involved proxy conflicts, cyberattacks, and targeted assassinations.
* The immediate catalyst was Israel’s initial strikes, which it justified by claiming Iran was close to developing a nuclear weapon, a day after the UN nuclear watchdog declared Iran wasn’t complying with nonproliferation agreements. Iran responded by stating it would create a new uranium enrichment facility.
* Experts are concerned about the potential for this conflict to escalate into a wider regional war, with implications for global energy markets.
* There are reports of discussions regarding regime change as a potential Israeli goal.
Why did you leave the coaching of the Pakistani team? Gary Kirsten opened his mouth

Gary Kirsten recently opened up about his reasons for leaving his coaching role with the Pakistan cricket team, citing a significant lack of influence and external interference. He was the white-ball coach, while Jason Gillespie was the Test coach, and both saw their tenures cut short.
Here are the key points from Gary Kirsten’s statements:
Lack of Influence in Selection: Kirsten stated that a primary reason for his departure was being removed from the selection panel. He felt that once he was “taken off selection and asked to take a team and not be able to shape the team, it became very difficult as a coach then to have any sort of positive influence on the group.” This lack of authority over team composition made his role largely ineffective.
External Interference: He hinted at significant “external influential noise” and “other agendas” that made it difficult to lead the team effectively. Kirsten emphasized that “Cricket teams need to be run by cricket people” and that when there’s a lot of outside interference, it’s hard for leaders to guide the team where it needs to go. He explicitly stated, “I’m too old now to be dealing with other agendas; I just want to coach a cricket team and work with the players.”
“No Unity” in the Team: Reports from during his tenure, specifically after Pakistan’s early exit from the T20 World Cup 2024, quoted Kirsten as saying there was “no unity” in the Pakistan team and that he had “never seen such a situation” in his coaching career. He reportedly stated that players were not supporting each other and were separated.
Short and Tumultuous Stint: Kirsten took over as Pakistan’s white-ball coach in April 2024 but resigned just six months into his job. He described these as “tumultuous few months.”
Despite the frustrating experience, Kirsten has not ruled out a potential return to coach Pakistan in the future, but only “under the right circumstances” and without the external interference he experienced previously. He expressed his fondness for the Pakistan players, acknowledging the immense pressure they face

ایک نئی تحقیق میں بتایا گیا ہے کہ یورپ، چین اور امریکا کو برقی گاڑیوں کے لیے لیتھیئم کی مقامی سطح پر پیداوار میں مشکلات کا سامنا کرنا پڑے گا۔
شینگھائی کی ایسٹ چائنا نارمل یونیورسٹی اور سوئیڈن کی لُنڈ یونیورسٹی کے محققین نے اس متوقع بحران کی نشان دہی کی جو ممکنہ طور پر موسمیاتی تبدیلی اور توانائی کے لیے تعین کیے گئے اہداف کے حصول میں مزید تاخیر کا سبب ہو سکتا ہے۔
تحقیق میں خبردار کیا گیا کہ 2030 تک مقامی سطح پر لیتھیئم کی پیداوار کو 10 گُنا تک بڑھا دینے کے باوجود تیزی سے بڑھتی طلب کو بغیر کسی ٹیکنالوجیکل جدت یا درآمدات میں اضافے کے پورا نہیں کیا جا سکے گا۔
عام طور پر کان کنی سے حاصل کیا جانے والا لیتھیئم برقی گاڑیوں کی بیٹریوں کے لیے بہت اہم ہوتا ہے۔ روایتی گاڑیوں سے ہونے والے کاربن اخراج میں کمی کے لیے برقی گاڑیوں کو بہت اہم دی جا رہی ہے، جس کے سبب یورپ، امرکا اور چین میں ان کی مانگ میں اضافہ ہو رہا ہے۔
