New Study Pinpoints Which US Metropolitan Areas Will Be Hottest. Unsplash

A new study predicts major U.S. population hot areas will be seeing the most extreme increases in heat in the coming decades, some of which could experience 30 times more extreme heat than previously predicted.

The study was conducted by researchers at Arizona State University and was published Monday in the Proceedings of the National Academy of Sciences.


Researchers made projections for extreme heat and cold exposure in 47 major cities in the U.S., accounting for population size, warming caused by urban development, and local standards for extreme heat.

To break down the local effects of global temperature rise, the research team measured the effect of heat in “person-hours” — defined as a human being exposed to extreme heat for one hour. They incorporated three metrics:

1. Local definitions of what an “extreme” temperature is;

2. How city environments change the effects of extreme heat;

3. the effect of population migration and growth.

The researchers considered local standards for extreme heat when making their calculations because, for example, a 100-degree day in locations like Pheonix or Austin, Texas, would feel not feel extreme to locals. The same heat in New York City could result in fatalities — especially among more vulnerable populations, like people who are elderly and homeless.

With that in mind, the researchers came up with two categories — absolute increases and relative increases in extreme heat.

Their top three cities for absolute increases in people affected by extreme heat include New York, Los Angeles, and Washington. The most intense relative increase — calculated by combining temperature factors with population growth — will be in places like Orlando, Miami, and Austin.

The researchers say because those cities are growing rapidly, more residents inevitably will be exposed to extreme heat, creating a bigger change relative to the beginning of this century. Atlanta, Georgia, made both lists.

The study team argues that cities must prepare at the local level to avoid the most serious illness and death resulting from extreme heat. They say key safety measures include having cooling centers and water available, as well as reliable sources of energy, as extreme heat can contribute to power outages. (VOA)

Fashion's biggest extravaganza, The Met Gala 2021, made a comeback with a vengeance after a skip in 2020 due to the pandemic.

Fashion's biggest extravaganza, The Met Gala 2021, made a comeback with a vengeance after a skip in 2020 due to the pandemic. The theme for this year's gala was 'In America: A Lexicon of Fashion', and as usual in attendance were a long list of celebrities including actors, musicians and sportpersons. Many fashion houses and celebrities chose to dazzle with the dark side of fashion as capes, leather, face masks and all kinds of drama unfolded at the event, as black ruling the red carpet with its darker vibe.

Met Gala regulars like Jennifer Lopez, Rihanna, Sharon Stone, Emily Blunt, Irina Shayk, Gigi Hadid and the Kardashian-Jenner siblings were spotted alongside debutantes like 18-year-old British tennis star Emma Raducanu who recently won the US Open, Rose Leslie from 'The Game of Thrones', gymnast Nia Dennis and Justin and Hailey Beiber who walked the Me carpet together for the first time.

The event is hosted by Vogue's Dame Anna Wintour and is held annually at The Metropolitan Museum of Modern Art in New York City. Here's a look at some of the stars who chose to walk on the darker side:

Are we just focused on post-heart attack action? Or should we be focused more on prevention?

Many young and middle-aged people today are dying of sudden heart attacks. Studies show that cardiovascular diseases (CVD) strike Indians a decade earlier compared to their Western counterparts. Why is this happening? How can we prevent it? Are we just focused on post-heart attack action? Or should we be focused more on prevention?

Luke Coutinho, Holistic Lifestyle Coach -- Integrative and Lifestyle Medicine shares an input that could prevent heart attacks at a young age:

Cholesterol is not the culprit, inflammation is: Many people believe that high levels of cholesterol and triglycerides are the sole culprits behind their heart attacks. The main reasons behind most heart attacks are inflammation and oxidative damage in the heart, blood vessels, endothelial lining, arteries, and more. While maintaining healthy cholesterol levels is important, we cannot blame heart attacks on cholesterol levels alone. What then can you do to keep inflammation in check and your heart strong? Adopt simple lifestyle changes.

When it comes to burgers, its not just the patty that makes it all worthwhile... one can't forget the cheese or the crunchy lettuce either.

When it comes to burgers, its not just the patty that makes it all worthwhile... one can't forget the cheese or the crunchy lettuce either. In India, McDonald's ensures their burgers use the freshest produce, which means that don't use any ordinary lettuce. The iceberg variety was first introduced in India by McDonald's, as early as the 90s, at a time when not many people were familiar with lettuce and used cabbage instead. Lettuce is a key ingredient known for its crunch, its odourless and is ideal for salads, sandwiches and burgers.

The fast food giant collaborated with local Indian suppliers and pioneered the local production of iceberg lettuce in the country. Their lettuce undergoes 30 quality and food safety checks. After harvesting, the lettuce is pre-cooled to a temperate of below 40C at the farm gate to maintain its freshness. It is then transported in refrigerated vehicles to the world-class processing plant where it is shredded to a measured length and width and then washed and cleaned thoroughly before being vacuum-packed.
