Dhaka, the overcrowded capital city of Bangladesh, has ranked 20th on the list of cities with the worst air quality with an AQI score of 82 at 10:25 am this morning (July 17, 2025). Today Dhaka’s air was classified as ‘moderate,’ referring to a light health threat, according to the AQI index. When the AQI value for particle pollution is between 50 and 100, air quality is considered ‘moderate’, usually sensitive individuals should consider limiting prolonged outdoor exertion, between 101 and 150, air quality is considered ‘unhealthy for sensitive groups’, between 150 and 200 is ‘unhealthy’, between 201 and 300 is said to be 'very unhealthy', while a reading of 301+ is considered 'hazardous', posing serious health risks to residents. Egypt’s Cairo, Dubai of United Arab Emirates, and Democratic Republic of the Congo’s Kinshasa cities respectively occupied the first, second and third spots on the list, with AQI scores of 220, 164, and 161 respectively. Dhaka’s air ‘unhealthy for sensitive groups’ this morning The AQI, an index for reporting daily air quality, informs people how clean or polluted the air of a certain city is and what associated health effects might be a concern for them. The AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone. Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon. As per World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, mainly due to increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.  

A small group of bottlenose dolphins in Shark Bay, Australia, has developed an unusual hunting method: using marine sponges as tools to catch fish. But new research shows that mastering this skill is far from easy. The dolphins wear the sponge on their beaks like a protective mask, allowing them to dig through the seabed without injury and flush out fish like the elusive barred sandperch. This technique, passed down from mother to calf, disrupts the dolphin’s echolocation abilities, making it harder to locate prey. “It has a muffling effect, in the way that a mask might,” explained Ellen Rose Jacobs, a marine biologist at Aarhus University and co-author of the study, published Tuesday in Royal Society Open Science. Despite this, dolphins adapt and continue using echolocation clicks to guide their foraging. Southern Europe scorched by extreme heatwaves as wildfire risks escalate Only about 5% of the local dolphin population—roughly 30 individuals—have mastered this behavior, likely because of the years of practice required. Sponge hunting, researchers say, is a rare cultural behavior passed exclusively from mother to offspring. Marine biologist Janet Mann of Georgetown University called it a delicate, inherited skill that not every dolphin learns to master. Source: Agency
