Heat + Humidity Gets Dangerous Faster Than Many People Realize – So How Hot Is Too Hot For The Human Body?

Heat waves are becoming supercharged as the climate changes – lasting longer, becoming more frequent and getting just plain hotter. One question a lot of people are asking is: “When will it get too hot for normal daily activity as we know it, even for young, healthy adults?” The answer goes beyond the temperature you see on the thermometer. It’s also about humidity. Our research shows the combination of the two can get dangerous faster than scientists previously believed. Scientists and other observers have become alarmed about the increasing frequency of extreme heat paired with high humidity, measured as “wet-bulb temperature.” During the heat waves that overtook South Asia in May and June 2022, Jacobabad, Pakistan, recorded a maximum wet-bulb temperature of 33.6 C (92.5 F) and Delhi t...

Physicists Give Chances Of Faster-Than-Light Space Travel A Boost – Warp Drives

The closest star to Earth is Proxima Centauri. It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph. It would take just 20 seconds to go from Los Angeles to New York City at that speed, but it would take the solar probe about 6,633 years to reach Earth’s nearest neighboring solar system. Faster than light travel is the only way humans could ever get to other stars in a reasonable amount of time. Les Bossinas/NASA/Wikimedia Commons If humanity ever wants to travel easily between stars, people will need to go faster than light. But so far, faster-than-light travel is possible only in science fiction. In Issac Asimov’s Foundation series, humanity can travel from...

To safely explore the solar system and beyond, spaceships need to go faster – nuclear-powered rockets may be the answer

With dreams of Mars on the minds of both NASA and Elon Musk, long-distance crewed missions through space are coming. But you might be surprised to learn that modern rockets don’t go all that much faster than the rockets of the past. There are a lot of reasons that a faster spaceship is a better one, and nuclear-powered rockets are a way to do this. They offer many benefits over traditional fuel-burning rockets or modern solar-powered electric rockets, but there have been only eight U.S. space launches carrying nuclear reactors in the last 40 years. However, last year the laws regulating nuclear space flights changed and work has already begun on this next generation of rockets. Why the need for speed? The first step of a space journey involves the use of launch rockets to get a ship into...

Why teen depression rates are rising faster for girls than boys

We’re in the middle of a teen mental health crisis – and girls are at its epicenter. Since 2010, depression, self-harm and suicide rates have increased among teen boys. But rates of major depression among teen girls in the U.S. increased even more – from 12% in 2011 to 20% in 2017. In 2015, three times as many 10- to 14-year-old girls were admitted to the emergency room after deliberately harming themselves than in 2010. Meanwhile, the suicide rate for adolescent girls has doubled since 2007. Rates of depression started to tick up just as smartphones became popular, so digital media could be playing a role. The generation of teens born after 1995 – known as iGen or Gen Z – were the first to spend their entire adolescence in the age of the smartphone. They’re also the first group of teens...
