The temperature the human body cannot survive-what NASA, others said
09.08.2023 - 10:39 / tech.hindustantimes.com
Scientists have identified the maximum mix of heat and humidity a human body can survive.
Even a healthy young person will die after enduring six hours of 35-degree Celsius (95 Fahrenheit) warmth when coupled with 100 percent humidity, but new research shows that threshold could be significantly lower.
At this point sweat -- the body's main tool for bringing down its core temperature -- no longer evaporates off the skin, eventually leading to heatstroke, organ failure and death.
This critical limit, which occurs at 35 degrees of what is known "wet bulb temperature", has only been breached around a dozen times, mostly in South Asia and the Persian Gulf, Colin Raymond of NASA's Jet Propulsion Laboratory told AFP.
None of those instances lasted more than two hours, meaning there have never been any "mass mortality events" linked to this limit of human survival, said Raymond, who led a major study on the subject.
But extreme heat does not need to be anywhere near that level to kill people, and everyone has a different threshold depending on their age, health and other social and economic factors, experts say.
For example, more than 61,000 people are estimated to have died due to the heat last summer in Europe, where there is rarely enough humidity to create dangerous wet bulb temperatures.
But as global temperatures rise -- last month was confirmed on Tuesday as the hottest in recorded history -- scientists warn that dangerous wet bulb events will also become more common.
The frequency of such events has at least doubled over the last 40 years, Raymond said, calling the increase a serious hazard of human-caused climate change.
Raymond's research projected that wet bulb temperatures will "regularly exceed" 35C at several points around the world in the coming decades if the world warms 2.5C degrees above preindustrial levels.
Though now mostly calculated using heat and humidity readings, wet bulb temperature was originally measured by putting a wet cloth over a thermometer and exposing it to the air.
This allowed it to measure how quickly the water evaporated off the cloth, representing sweat off of skin.
The theorised human survival limit of 35C wet bulb temperature represents 35C of dry heat as well as 100 percent humidity -- or 46C at 50 percent humidity.
To test this limit, researchers at Pennsylvania State University in the United States measured the core temperatures of young, healthy people inside a heat chamber.
They found that participants reached their "critical environmental limit" -- when their body could not stop their core temperature from continuing to rise -- at 30.6C wet bulb temperature, well below the previously theorised 35C.
The team estimated that it would take between five to seven hours before such

Eying the iPhone 15 Pro? Here is what you are likely to get
The countdown to the release of the Apple iPhone 15 launch has begun, with expectations soaring for the September 2023 launch. Four models are set to debut in the lineup: the standard iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. The iPhone 15 series will be launched with Apple seeing a big slowdown in sales in the US as well as a global smartphone slowdown. In effect, that means, Apple will have to make sure its Pro smartphones pack the kind of game-changer tech that fans have come to expect from the tech major rather than the relatively minor changes that have been rolled out over the last few years.

What We Played #616 – Madden 24, Baldur’s Gate 3 & Blasphemous 2
We’re already halfway through August! How did that happen? What that means in terms of the gaming world is that it means Gamescom in Cologne is next week, and we’ll be at the conference to bring you coverage of as many games as possible (we’re seeing about 50 between us!). In the meantime I’ve been playing a lot of American football as the preseason of the NFL has started. That’s been lots of Legend Bowl, and then a heap of Madden 24 in the last two days. We’re not quite ready to put a score on it, but we’re impressed so far. Besides that I’m trying to get through Baldur’s Gate 3, and it is overwhelmingly big. It’s wonderful too.

AI to reduce aircraft emissions? Look what Google and American Airlines are doing
Artificial Intelligence (AI) is emerging as a promising avenue for a huge number of human activities - from plain and simple writing to top-notch medical intervention. Now, it is being deployed to curb aircraft emissions! The initiative has been announced by Google and it is collaborating with American Airlines for the purpose. The joint initiative aims to pioneer a novel technology capable of aiding pilots in minimising contrail emissions, those distinctive white streaks trailing across the sky left by aircraft that consist of water vapour and ice particles.

Chandrayaan-3 moon mission: Know what’s coming next
Indian Space Research Organization (ISRO)'s Chandrayaan-3 mission could not have had a better start, with the lander commencing its deboosting process today. The mission, which launched on July 14 from the Satish Dhawan Space Centre Second Launch Pad in Sriharikota, is India's second attempt to touchdown on the surface of the Moon. In its latest maneuver on July 17, the lander separated from the propulsion module and will now begin its descent towards the lunar south pole.

Scientist says AI will cause virus outbreak, nuclear war and human extinction
The fear of artificial intelligence (AI) endangering human existence is not new. Since AI first began making waves, experts have expressed concern about this technology that can hypothetically even gain sentience one day. In 1950, American writer Isaac Asimov published his book "I, Robot", which explored this theme. Then, in 1984, James Cameron's film The Terminator took the stage and showcased the killer AI that caused the apocalypse. However, in 2023, those who are expressing concerns are entrepreneurs that are working with this technology, governments, and AI scientists themselves. Recently, one AI expert stated that AI will cause the first extinction event for humans by triggering events such as nuclear war and virus outbreaks.
