A new study by researchers at the University of Oxford suggests that producing organic and free range eggs may have a greater impact on the environment than eggs produced by hens kept in conventional cage systems.

According to the research if all egg production switched to organic and free range farming carbon emissions could increase by about 60%.

The amount of land needed for egg production would also nearly double.

The researchers estimated that producing only organic and free range eggs would release around 2.316 million tonnes of carbon dioxide equivalent greenhouse gases.

In comparison producing eggs only from caged hens would generate about 1.184 million tonnes.

The study explains that while organic and free range systems are often considered better for animal welfare they require more hens to produce the same number of eggs.  This is because hens kept in cage systems generally lay eggs more efficiently.

Researchers also warned that organic and free range farming may require more land and could have a greater impact on water pollution.

The study’s lead author, Dr. Harriet Bartlett said that future decisions about egg production should carefully balance three important factors animal welfare environmental impact and the need to produce enough food.

    Begging has become a growing problem in many cities of Pakistan. It is common to see children women and elderly people begging at traffic signals markets and public places.   While some are genuinely poor many are forced into organized begging networks that exploit them for money. Instead of encouraging begging by giving cash, society should support charities, shelters and welfare programs that help people become self reliant.   The government must also take strict action against begging mafias provide vocational training and create employment opportunities for those in need. By addressing the root causes of poverty and exploitation we can help people live with dignity rather than depend on begging

  • Why your brain may need a phone break

    Smartphones have become a major part of everyday life. Many people check their phones as soon as they wake up and continue using them until bedtime. But have you ever wondered how constant phone use may affect your brain? A new study suggests that limiting smartphone use for just 72 hours may lead to changes in brain activity. What did the study find? Researchers from Heidelberg University and the University of Cologne in Germany studied 25 young adults between the ages of 18 and 30. The participants were asked to reduce their smartphone use for three days. They could still use their phones for essential tasks and important communication. Before and after the three-day period the participants underwent MRI brain scans and psychological tests. The researchers noticed changes in brain areas linked to the brain’s reward system and addictive behaviors. How did smartphones affect brain activity? During the brain scans participants were shown different pictures, including smartphones as well as everyday objects such as boats and flowers. After just three days of limited smartphone use researchers observed changes in how certain areas of the brain responded to these images. The findings suggest that our relationship with smartphones may involve more than simple communication.  The desire to check a phone can also be connected to social interaction and the brain’s reward system. Should you take a break from your phone? The study raises an interesting question about how regular smartphone use may affect the brain over time. If reducing phone use for only 72 hours can be linked to changes in brain activity researchers say it is worth exploring what might happen when people reduce their screen time for longer periods. Could a digital detox help? Taking regular breaks from smartphones may be a useful habit. Spending less time on your phone can give you more opportunities to focus on other activities spend time with people and take a break from constant notifications. A simple digital detox may also help you create healthier phone habits and give your mind some much needed time away from the screen. The bottom line Smartphones are useful tools but using them constantly may not be ideal.  Taking short regular breaks from your phone could be a simple way to build a healthier relationship with technology.

  • The tragic fate of Aurangzeb’s rebellious daughter

    In the residential quarters of Nawan Kot in Lahore stands a crumbling Mughal monument. To a casual bystander, it appears as little more than a neglected relic surrounded by modern brick houses and the distant roar of traffic from Multan Road. Yet, local legend fiercely protects this spot as the resting place of Princess Zeb-un-Nissa, the eldest daughter of the orthodox Mughal Emperor Aurangzeb. Historians, however, tell a very different story. Official records indicate that Zeb-un-Nissa died in Delhi at the Salimgarh Fort after two decades of imprisonment and was buried outside the Kashmiri Gate at the Tees Hazari gardens. Her original tomb was later dismantled during the British era to make way for a railway line. So how did a city hundreds of miles away come to claim this defiant, romantic princess as its own? The answer lies not in verified architectural blueprints, but in the psychological and political pulse of 17th-century Lahore. Zeb-un-Nissa was an anomaly in the puritanical Mughal court of her father. She was highly educated, exceptionally wealthy, a scholar of theology, and a devout patron of the arts. Under the secret pen name Makhfi (The Hidden One), she wrote expressive, Sufi-inspired poetry that directly challenged the orthodox ethos. Her political inclinations further alienated her from her father. Zeb-un-Nissa had strong affinities for her uncle, Prince Dara Shikoh: Aurangzeb’s primary rival for the throne. It was originally betrothed to his son, Prince Suleiman Shikoh. After Aurangzeb executed both Dara and Suleiman during the violent war of succession, Zeb-un-Nissa reportedly vowed never to marry. Later in life, her secret correspondence supporting her rebellious younger brother, Prince Muhammad Akbar, ultimately led to her downfall and life imprisonment. Lahore’s local folklore transformed her political tragedy into a narrative of star-crossed love. Popular stories in the city recount a passionate, poetic romance between Zeb-un-Nissa and Akil Khan Razi, the Governor of Lahore. According to local legend, after Emperor Aurangzeb forbade their union, the heartbroken princess renounced her royal luxury and retreated to a self-imposed prison in her private estate near Chauburji. In this garden sanctuary, she allegedly ran a massive public kitchen (langar) to feed dervishes, beggars, and travelers, using poetic riddles on slips of paper to communicate with the needy and eventually, to secretly reconnect with her disgraced lover. When Aurangzeb discovered their continued meetings, legends claim he ordered Akil Khan’s brutal execution and permanently confined his daughter within the garden walls. While these romantic tales lack strict historical evidence, they reflect a deeper cultural reality. Lahore had been the favorite city of Dara Shikoh, who poured immense imperial funds into its cultural and architectural enrichment. When Aurangzeb seized power, executed Dara, and shifted the imperial capital away from the city, Lahore was left politically marginalized and financially neglected. In an age where open political dissent against an absolute monarch was impossible, the citizens of Lahore used rumors, myths, and urban legends as their primary medium of protest. Zeb-un-Nissa: a brilliant woman who shared Dara Shikoh’s inclination toward Sufism, loved the city of Lahore. She publicly defied her father’s authority became the ultimate symbol of the city’s lost artistic spirit. By adopting her memory, attributing the Chauburji gardens to her patronage, and declaring the tomb in Nawan Kot as her final resting place, Lahore claimed the rebellious princess as its own. In doing so, the city permanently etched her spirit of resistance into its own historical identity.  

  • Scientists propose nuclear plan to stop Earth-bound asteroids

    Beijing: Chinese scientists have proposed a new planetary defense strategy to deflect or destroy potentially hazardous asteroids that could collide with Earth. According to the proposed approach, placing a nuclear device inside an asteroid and detonating it could be one of the most effective ways to deal with a major impact threat. According to a report, researchers at the China Academy of Launch Vehicle Technology said that large asteroids have always posed a serious threat to human civilization. In the distant past, asteroid impacts caused mass extinctions and triggered devastating environmental changes. The scientists noted that astronomers have discovered several asteroids hundreds of meters wide passing very close to Earth in recent years prompting increased research into new planetary defense methods. The study suggests that a nuclear explosion could be the most effective strategy for either destroying a large asteroid or deflecting it away from Earth particularly when there is very little time to respond. Under the proposed plan, a spacecraft would first create a deep crater on the asteroid. A nuclear device would then be placed inside the crater and detonated to alter the asteroid’s trajectory or break it into smaller pieces. According to the research, a 100-meter-wide asteroid could be completely destroyed by an explosion with a yield equivalent to 200 times the atomic bomb dropped on Hiroshima. Similarly, detonating a nuclear device at a depth of 20 meters inside an asteroid about one kilometer wide could change its velocity enough for it to safely miss Earth. The researchers said the study could help pave the way for future planetary defense strategies against large near-Earth asteroids.

  • How far can you drive after low fuel light comes on?

    ByJustpaste.in

    If you fail to keep an eye on your fuel level while driving, your car could eventually come to a stop. When a car is about to run out of fuel, a warning indicator commonly known as the low fuel light illuminates on the dashboard. But how far can you actually drive once this light comes on? The answer can be useful if there isn’t a fuel station nearby. However, there is no single answer as it depends on several factors including the car’s make and model, model year, driving habits, fuel efficiency and road conditions. According to experts, once the low fuel warning light turns on, the vehicle cannot travel very far. The good news, however, is that it can usually go farther than many people expect. Experts say the warning light typically comes on when the fuel tank has around 10 to 15 percent of its capacity remaining. On average, small cars can travel about 20 to 30 miles (32–48 km) after the light comes on while larger vehicles may cover up to 50 miles (80 km). However, if the vehicle is old or the road conditions are poor, the remaining driving range may be significantly shorter. Cold weather can also increase fuel consumption reducing the distance the car can travel after the warning light appears. Experts further caution that continuing to drive for an extended period after the low fuel light comes on may damage the engine although driving a few additional miles is generally unlikely to cause any harm.

    Chiniot: A family in Chiniot is still waiting for justice in a theft case that was reportedly registered shortly after Pakistan came into being in 1947. The case dates back nearly 80 years. According to the affected family, a large amount of gold silver expensive clothes and other valuables were stolen from their home on the night between August 14 and 15, 1947. The family says the case was among the first cases registered in Chiniot after independence and was recorded as FIR No. 8. According to the family, around 112 to 120 tolas of gold, silver items, Boski fabric and other expensive clothes were stolen.  The value of these items would be worth millions of rupees today. Despite the passage of almost eight decades the stolen property has never been recovered and the family says there is still no clear record of what happened to the case. To mark 80 years of waiting for justice the family held a unique protest. They had a cake made featuring the text of the old FIR and cut it to draw the attention of the authorities. Family members say their elders spent years visiting police stations and courts in the hope of recovering their belongings.  However several generations have passed without any clear result. A family member Sajid Ismail Dar, said that applications had also been submitted to senior Punjab Police officials in the past.  Some officials took notice of the matter but the case later went quiet again. The family has now appealed to the Inspector General of Punjab Police and the Chief Minister of Punjab to review the decades old case investigate whether the stolen property can still be traced and provide justice to the family.
