Vancouver is a major city in western Canada, located in the Lower Mainland region of British Columbia. As the most populous city in the province, the 2016 census recorded 631,486 people in the city, up from 603,502 in 2011. The Greater Vancouver area had a population of 2,463,431 in 2016, making it the third-largest metropolitan area in Canada. Vancouver has the highest population density in Canada, with over 5,400 people per square kilometer. Vancouver is one of the most ethnically and linguistically diverse cities in Canada: 52 percent of its residents are not native English speakers, 48.9 percent are native speakers of neither English nor French, and 50.6 percent of residents belong to visible minority groups.
Vancouver is consistently named as one of the top five worldwide cities for livability and quality of life, and the Economist Intelligence Unit acknowledged it as the first city ranked among the top ten of the world’s most well-living cities for ten consecutive years. However, Vancouver also ranks as the most expensive city to live in Canada and as the fourth-most expensive housing market globally. In 2011, the city planned to become the greenest city in the world by 2020. Vancouverism is the city’s urban planning design philosophy. Wikipedia
With eight separate, flexible plates of shell held together by a skirt of muscle called a girdle, chitons look a bit like armored pebbles, ready for battle. The marine mollusks aren’t actually suited for action. They spend most of their time stuck in place, suctioned to rocks in the intertidal zone. While they’re clinging, their radula, a sort of tongue barbed with scores of sharp “teeth,” scrapes algae and other food from the surface. For chitons, that’s about as exciting as it gets.
They might seem simple, uncomplicated, even boring, but Lauren Sumner-Rooney, an evolutionary biologist at the Oxford University Museum of Natural History, thinks that reputation is a little unfair. “Even things that we’ve considered very, very simple,” she says, “may have a lot more going on.”
Sumner-Rooney roots for underdogs. She’s fascinated, for instance, by Astyanax mexicanus, a cave-dwelling tetra fish that evolved without eyes, and cave salamanders, whose ghostly pallor and gangly limbs are adapted to a lightless life. Her work focuses on brain structure in poorly understood animals such as chitons or tusk shells, which use tentacle-like organs called captacula to assist in gathering food.

The scene is a familiar one: an urban park, with young couples picnicking, dog owners playing fetch, parents chatting while their children scamper around. Marie – a young child – becomes entranced by a new wonder of her world – maybe a springtime butterfly, maybe another child throwing an impressive fit. Eventually, looking away from her intense focus, she realizes that the world has shifted around her and that her parents are no longer in sight. Interest and elation morph into concern and fear, as she holds back her tears and begins to search. Just around the corner, she finds her father, who scoops her up, and, as quick as her fear started, it dissipates; her world is complete and safe again.
From the moment we are born, we are hardwired to seek attachment to others. Throughout our lives, relationships that involve attachment serve as sources of emotional security, joy, and companionship, while at other times, pain and grief. Compared with those of other animals, human relationships are staggeringly multifaceted. Yet despite this, what lies at the core of our relationships is an elaboration of a phenomenon whose roots across the species spectrum are wide and deep. As we wend our way through life’s course – from infancy to adolescence to adulthood to loss – attachment holds a strong grip on our lives, shifting to accommodate our changing needs. While the roots of this phenomenon tell us much about who we are, they tell us just as much about mysteries that remain unanswered in evolution, psychology, neuroscience, and more.
The Baltic Sea is an arm of the Atlantic Ocean, enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden, and the North and Central European Plain.
The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt, and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga, and the Bay of Gdańsk.
The Baltic Proper is bordered on its northern edge, at latitude 60°N, by the Åland Islands and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula.
The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea-Baltic Canal and to the German Bight of the North Sea via the Kiel Canal. Wikipedia
In late June, when temperatures climbed to 115 degrees in Portland, Oregon, houses and buildings across the Pacific Northwest were caught way off guard. Most were designed for much cooler temperatures, with insulation and ventilation tuned to handle moderate highs and lows. Typically, even on hot days, the evening lows would be cold enough to bring down the overall temperature of buildings, keeping them from turning into roasting ovens. Air conditioning was typically irrelevant, and buildings could usually stay comfortable passively, or without much intervention.
But that was before. The heatwave showed that temperatures can and probably will continue to be higher than in previous decades. The low- or no-effort temperature control that has been designed into the region’s homes likely won’t be able to keep up, according to Mike Fowler, an architect at Seattle-based Mithun. “We’re going to phase out of that by the end of the decade. And this has been eye-opening for a lot of folks,” he says.
A new type of building design will be needed in the Pacific Northwest sooner than most people expected, he says, but design approaches that are regularly used in hotter, more extreme climates offer some clues for how architecture will need to evolve.
Are you an ecosystem? Your mouth, skin, and gut are home to whole communities of microscopic organisms, whose influence on your body ranges from digesting your food to training your immune system and, possibly, impacting your mood and behavior. What are these tiny tenants, and how do they change the way we think about human health, disease, and even identity?
The human body is made up of trillions of cells—well, trillions of human cells. Around the beginning of the 21st century, scientists learned that in fact, the human body contains many trillions more microbial cells—possibly three times as many. This is the microbiome: the collection of microorganisms (bacteria, fungi, and other microbes) living in and on the human body. It is an especially curious discovery—it has been with us, evolving, interacting, and helping to determine our fate as organisms, since before the emergence of the human species itself. And while scientists have known about the existence of some microorganisms on and in the human body since the discovery of E. coli, the magnitude, and importance of the microbiome has only recently begun to come to light.
Valencia, is the capital of the autonomous community of Valencia and the third-largest city in Spain after Madrid and Barcelona, surpassing 800,000 inhabitants in the municipality. The wider urban area also comprising the neighboring municipalities has a population of around 1.6 million. Valencia is Spain’s third-largest metropolitan area, with a population ranging from 1.7 to 2.5 million depending on how the metropolitan area is defined. The Port of Valencia is the 5th-busiest container port in Europe and the busiest container port on the Mediterranean Sea. The city is ranked as a Gamma-level global city by the Globalization and World Cities Research Network.
Valencia was founded as a Roman colony by the consul Decimus Junius Brutus Callaicus in 138 BC and called Valentia Edetanorum. In 714, Moroccan and Arab Moors occupied the city, introducing their language, religion, and customs; they implemented improved irrigation systems and the cultivation of new crops as well. Valencia was the capital of the Taifa of Valencia. In 1238 the Christian king James I of Aragon conquered the city and divided the land among the nobles who helped him conquer it, as witnessed in the Llibre del Repartiment. He also created the new Kingdom of Valencia, which had its own laws (Furs), with Valencia as its main city and capital. In the 18th century, Philip V of Spain abolished the privileges as punishment to the kingdom of Valencia for aligning with the Habsburg side in the War of the Spanish Succession. Valencia was the capital of Spain when Joseph Bonaparte moved the Court there in the summer of 1812. It also served as the capital between 1936 and 1937, during the Second Spanish Republic. Wikipedia
It’s a good time to look up. One of the year’s most spectacular skywatching shows, the annual Perseid meteor shower, is back to light up the night sky.
The Perseid meteor shower peaks in mid-August, when up to 100 meteors can be seen per hour, but the celestial event will be active beginning Wednesday, which means shooting stars may be visible on clear nights starting this week. The Perseids are considered “the best meteor shower of the year,” according to NASA.
In the Northern Hemisphere, the best way to view the Perseids is to head out in the predawn hours, though some meteors may be visible earlier, from 10 p.m. onward, according to NASA. Meteor showers are best viewed from places that are away from city lights, as light pollution can drown out the shooting stars.
The Perseid meteor shower is called that because the shooting stars appear to stream from a point in the sky where the constellation of Perseus is located. While the constellation is not the source of the meteors, it can help skywatchers figure out where to look.

In the world, human beings are facing various problems. People who are full of greed, anger, and ignorance are seen to be fighting with each other in words and deeds. As the fighting continues, various problems such as civil wars, wars of aggression, and wars of aggression are occurring. As world peace is being destroyed, humans are facing unbearable problems. Innocent children and women are not getting the rights they deserve and deserve. I can't think of one thing every time. What is it? The United Nations. If we look at the responsibilities and duties of the United Nations, I think it is not suitable for solving the problems that are happening in the world today. In fact, the United Nations and the World Security Council, such an organization must rule the world, must be able to give orders, and must have various ways to obey orders. There must be no organization that can influence more than that organization. There should be experts from each country. They can even dominate the superpowers like the US, China, and Britain. Only then will global peace be achieved quickly. Now, if a country with power develops more militarily, economically, or socially than its own country, then powerful countries will jealously seek out enemies and wage war. Or they will attack with fighter jets. In this, innocent people are losing their lives. No one understands the value of a life. You should think about how to achieve global peace by controlling these. If the US continues to be the permanent president of the UN, world peace will never be achieved. If you think carefully, no one sees that they are working for the common good, but for their own benefit, for the benefit of their own country. The permanent president of the UN and the Security Council has rejected this, As a young Rohingya, I have come to realize that only by electing the president and secretary from among the countries in the world through a secret ballot system and governing the world fairly can we achieve global peace. The United Nations and the Security Council are organizations in which any country must govern, give orders, and make them obey their orders. For example, only when a defendant is tried in court can we hold the leaders of the countries in check and control them, can we achieve global peace smoothly. Otherwise, it will not be easy for powerful countries to use various excuses to end this war every year, every year, for the benefit of themselves and their countries. No country's leaders pay any attention to the words of the United Nations and the Security Council. If we look at it in practice, look at the Rohingya issue. Myanmar is a small country. Even that country has been under siege for 8 years. What action can be taken? Why is the UN and the Security Council Powerless? Without such Power, how can the organization bring about global peace? Everyone should think about it. Whether there is a veto or a strong one, all countries in the world can only achieve global peace if they are subject to the UN and the Security Council. Seek peace in the quiet embrace of nature. Peace is an indispensable need of the human race. It is not as if one person can kill another person, and it is as if one country can attack another country, but instead of trying to build peace, we must try to destroy the peace now, and the world is getting hotter and is on the verge of collapse. I especially appeal to all the world experts to urgently try to bring about peace in all parts of the world. Mr, Noor Muhamed Arkhan Rohingya Youth Myanmar
