Many people still believe that dogs see the world in black and white. This common myth has been around for decades, but modern science proves it wrong. In reality, dogs can see colors — just not in the same way humans do. Understanding how dogs see colors helps pet owners better communicate with their animals and improve their everyday life. This article explains how dogs see colors , why their vision is different , and what it means for your pet’s behavior, toys, and environment. Do Dogs See in Black and White? No, dogs do not see the world in black and white. Scientific studies confirm that dogs have color vision, but it is limited compared to humans. This difference is due to the structure of their eyes. Humans have three types of color receptors (cones) in the retina, allowing us to see a wide range of colors — red, green, and blue. Dogs, however, have only two types of cones. This means their vision is similar to a human with red-green color blindness. What Colors Can...

NASA’s $20B Moon Base: Why They Cancelled the Lunar Gateway and What It Means for Space Exploration NASA is making headlines again. The agency, under new Administrator Jared Isaacman , has announced it will spend $20 billion on a permanent NASA moon base on the lunar surface. At the same time, NASA is cancelling plans for the Lunar Gateway — the orbiting space station that was supposed to serve as a stepping stone for Artemis missions. Instead, those components will be repurposed directly for lunar base construction . This is not just a budget shift — it’s a game-changing pivot toward sustained human presence on the Moon. 5 6 Why NASA Is Building a $20 Billion Lunar Base Now The decision comes straight from the top. In a major address at NASA headquarters on March 24, 2026, Administrator Jared Isaacman explained: “It should not really surprise anyone that we are pausing Gateway in its current form and focusing on infrastructure that supports sustained operations on the lunar ...

The rapid expansion of ocean floor mapping has become one of the most important developments in modern geopolitics and oceanography .

In the world of Pompeii archaeology , few discoveries have captured the imagination like the recent revelation of traces of bombardment from a high-tech ancient crossbow on the city’s ancient walls. Italian researchers have uncovered compelling evidence that Roman forces deployed a revolutionary repeating weapon — the polybolos — during the siege of Pompeii in 89 BC. This “ancient machine gun” left distinctive marks that survived the catastrophic eruption of Mount Vesuvius nearly a century later. This groundbreaking Pompeii archaeology find rewrites our understanding of Roman military technology and offers a fascinating glimpse into the high-tech warfare of the past. Read on to discover how and why these traces were identified, who made the discovery, and what it means for history. The Siege of Pompeii: A Dramatic Chapter in Ancient History Long before the famous AD 79 eruption buried Pompeii under ash and pumice, the city faced a brutal siege during the Social War (91–88 BC)...

Meningitis B is one of the most dangerous bacterial infections affecting infants, teenagers, and young adults. It can progress rapidly and cause life-threatening complications within hours. That is why vaccination against meningococcal group B (MenB) is considered one of the most important preventive health measures today. According to global health experts and UK medical authorities, early vaccination can dramatically reduce the risk of severe illness, disability, and death. This article explains how and why the MenB vaccine works, the UK vaccination schedule, real-life examples, and expert opinions. What Is Meningitis B? Meningitis B is a bacterial infection caused by Neisseria meningitidis group B. It leads to inflammation of the membranes surrounding the brain and spinal cord. Symptoms often include fever, headache, stiff neck, vomiting, sensitivity to light, and confusion. In severe cases, it can cause sepsi...

In the heart of bustling cities, urban wildlife faces dangers we rarely consider. While many think of wildlife threats as happening in remote forests, everything is the opposite when it comes to animals in urban areas. Discarded human litter is now turning everyday city squirrels into unwitting "vapers." Yes, squirrels are 'vaping' e-cigarettes after mistaking fruity aromas for food. This alarming trend highlights growing threats to urban wildlife and shows how our daily habits endanger animals wildlife right in our neighborhoods. At Natural World 50 , we explore these hidden dangers to help protect nature in cities. The Viral Incidents: Squirrels Caught 'Vaping' in City Parks Recent videos circulating on social media have captured grey squirrels in south London’s Brixton park and Philadelphia holding disposable vapes between their paws and chewing on the mouthpiece. One squirrel perched on a fence, appearing to "vape" as it nibbled the...

Time is one of the most fundamental aspects of our existence. We measure it, feel it, and live by it. But what if time is not what we think it is? What if time is simply a construct of the human mind? Modern science , including physics and cosmology, still struggles to fully define what time actually is. Despite centuries of research, scientists are left with more questions than answers. What Is Time in Science? In classical physics, time is treated as a constant — something that flows uniformly, independent of everything else. However, this idea changed dramatically with the development of modern physics. According to relativity, time is not fixed. It can stretch, slow down, and even bend depending on speed and gravity. This means time is not absolute — it is relative. Learn more from this trusted scientific source: https://www.space.com/29859-the-illusion-of-time.html Why Time Feels Real Humans experience time as a continuous flow from past to pr...

Nature teaches and shocks at the same time! For centuries, people believed ravens simply trailed wolves across the wilderness, waiting for scraps from fresh kills. But groundbreaking research turns this myth upside down. Ravens do not just pursue wolves – they remember places of kills at huge distances using astonishing spatial memory . In the wild heart of Yellowstone National Park , these intelligent birds create mental maps of "resource landscapes" where wolf kills happen most often. They fly straight back to these hotspots – sometimes from 155 kilometers (96 miles) away – without needing to shadow the predators in real time. This discovery reveals the true depth of the ravens and wolves relationship and showcases remarkable animal intelligence that continues to amaze scientists. The Old Myth vs. the Shocking New Reality Long-standing folklore and early wildlife observations painted ravens as loyal followers of wolves. In many cultures, the two species appear t...

Listen to smart people! The USA and the White House should have heeded Pope Francis’ powerful call for alternative energy . In his groundbreaking encyclical Laudato Si’ , the Pope urged the world to move away from fossil fuels toward renewable energy and clean energy . Yet powerful interests stood in the way. Today, the environmental damage and economic costs scream louder than ever: why didn’t America listen? What Exactly Did Pope Francis Say About Clean Energy? In paragraph 26 of Laudato Si’ (May 24, 2015) , Pope Francis wrote clearly: “There is an urgent need to develop policies so that, in the next few years, the emission of carbon dioxide and other highly polluting gases can be drastically reduced, for example, substituting for fossil fuels and developing sources of renewable energy. Worldwide there is minimal access to clean and renewable energy.” He repeated the message in paragraph 165: “We know that technology based on the use of highly polluting fossil fuels — espec...

Seas and oceans hold the key to understanding one of the most pressing challenges of our time. What if the baseline for sea level rise calculations has been wrong all along? A groundbreaking 2026 study published in Nature reveals that actual coastal sea levels are significantly higher than most scientists previously assumed. This discovery by Dr. Philip Minderhoud and Katharina Seeger from Wageningen University & Research is forcing experts to rewrite projections for climate change impacts worldwide. Why does this matter? Because it means millions more people are already living in zones vulnerable to coastal flooding and rising sea levels than previously calculated. The findings don’t just tweak numbers — they completely reshape our understanding of future catastrophes in oceans and seas. How Did Scientists Get Sea Levels Wrong? The problem lies in a fundamental mismatch between how land elevation and ocean heights are measured. Most coastal hazard assessments rely on “ge...
