Scientists have explored the hypothetical scenario of drilling through the Earth's layers to the other side. The process would require a massive drill and decades of work. The deepest human-made hole, the Kola Superdeep Borehole in Russia, is only 7.6 miles deep, far from reaching the mantle, which is about 50 miles away. The extreme pressures and temperatures, such as 2,570 degrees Fahrenheit in the mantle and 7,200 to 9,000 degrees Fahrenheit in the outer core, would pose significant challenges. Additionally, the drill would have to overcome the pull of gravity and work against it to reach the other side.

Hotshot fire crews, elite U.S. firefighters who battle the biggest wildfires in the American West, work in extreme conditions for long periods of time, often without access to basic amenities like showers or cellphone signals. They use hand tools and chain saws to carve out dirt tracks to control the spread of fires. Despite the dangers and low pay, hotshots are drawn to the camaraderie and the challenge of the job. A report by the University of Washington highlights the pay disparity between federal firefighters and their counterparts in state agencies, leading to legislation that aims to raise the base pay of entry-level federal firefighters.

A team of scientists from Argentina, Chile, Bolivia, and the United States have discovered 13 mummified mice at elevations above 6,000 meters in the Andes mountains, making them the world's highest dwelling mammal. The mice, called Phyllotis vaccarum, are commonly found at lower elevations but have been found at extreme heights on the Atacama Plateau. The harsh conditions, similar to those on Mars, create perfect conditions for preservation. The researchers are conducting further studies to understand how the mice survive in these extreme conditions and are exploring theories such as their diet of lichens or the transportation of food by wind. This discovery challenges previous beliefs about species' survival capabilities in high-altitude environments.

Scientists have discovered a new phase of high-density, ultra-hot ice called Ice XIX, which could exist in the interiors of gas giants like Uranus and Neptune. Using high-power lasers and X-ray laser facilities, researchers observed the body-centered cubic structure of Ice XIX, with freely moving hydrogen atoms that dramatically increase conductivity. This discovery provides insight into the complex magnetic fields observed by the Voyager II spacecraft and expands our understanding of water ice under extreme conditions.

The PGA Tour is taking additional measures to ensure player and caddie hydration and reduce health concerns during the ongoing heatwave. Coolers with water and electrolyte drinks, shade tents with misting fans, and CoolMitt devices are being provided on every third hole. The Tour has also reminded players that IV fluids over 200 ml are prohibited due to anti-doping policies. Trainers are emphasizing the importance of staying hydrated and replenishing electrolytes to combat the extreme heat and its effects on cognitive ability and energy loss.
