The surprising world of coal seam fires

The world's longest-burning fire

This coal fire in New South Wales, Australia, a common occurrence at coal mines, has been burning for at least 5,500 years, and shows no signs of stopping.

The resurgence of Black lung disease in coal miners

Black lung disease is a preventable condition long associated with coal miners who regularly breathe in toxic coal dust. Simple workplace safety procedures make the disease entirely preventable, but cases are rising. Due to lax enforcement of rules, miners in Central Appalachia are increasingly diagnosed with cases stemming from silica dust inhalation.

Spontaneous combustion involves an object igniting on its own

Even without matches, sparks, or external flames, exothermic chemical or biological reactions can increase the internal temperature of objects to the point where they reach a threshold temperature that can cause them to catch fire. Running batteries and fermenting bacteria within compressed materials can build this heat and cause combustion.

Exploring carbon compound pore structures contributed to improved gas mask filtration

During World War II, the British Coal Utilisation Research Association sought to improve the efficiency of coal as an energy source and studied the effectiveness of charcoal filters to keep soldiers safe. Rosalind Franklin's research there formed the basis of her PhD and led to five scientific papers.

Across a 20-year period, methane has more than 80 times the warming potential of CO₂

However, this greenhouse gas lasts only about 12 years in the atmosphere, much less than the centuries or more that carbon dioxide can persist. Methane is produced primarily during the production, storage, and transmission of coal, natural gas, and oil, as well as from the digestive processes of domestic livestock.

Barbecue is a cooking style practiced across the globe

How many ways are there to cook meat over a fire? Tons, it turns out. Every continent, barring Antarctica, has a local version (or versions) of barbecue. For instance, in Japan, it’s meat-laden skewers cooked over Japanese oak charcoal. Head down to Argentina, and you’ll find parillas—open-flame grills that impart a smoky char to the ingredients.

Understanding the causes and environmental impacts of crude oil spills and leaks

Although some oil regularly leaks from the bottom of the oceans through the gradual erosion of sedimentary rock, major spills result from accidental ruptures of pipelines or damage to transportation vessels or rigs. Oil can break down the water-repelling ability of feathers, remove the insulation of fur, and poison food chains if ingested.

How a polluted New York City waterway created extremophiles hungry for 'black mayonnaise'

In the 19th century, coal processing plants, oil refineries, a tannery, and other industries lining the Gowanus Canal contaminated its waters with coal tar, sewage, and other pollutants, forming the toxic sludge. Samples taken from the site before clean-up efforts revealed over 450 species of microbes with metabolisms adapted to break down these contaminants.

What happens if you throw trash into lava?

Each year, the world generates more than 2 billion tons of waste. Some have wondered: Could we dispose of it in lava? This video explores the science behind that idea, from lava lake temperatures to steam explosions and toxic emissions, and why the risks outweigh the benefits.

How fighting wildfires works

Firefighters use sophisticated strategies to control wildfires that sometimes cover thousands of acres. This video breaks down how teams set up fire lines to isolate the fires by cutting down brush and trees around the existing fire, among other...

The hidden engineering of gas stations

Contemporary gas stations are the result of a century of engineering progress. In the early 1900s, only a few thousand cars drove around, and they used kerosene. As vehicles and cheaper gasoline became more popular, fire hazards grew, forcing the invention of fuel pumps, underground storage tanks, and the automatic shutoff valve—all engineering marvels.

Watch David Attenborough’s documentary on bioluminescent creatures

Sea creatures can make their bodies glow to camouflage themselves by mimicking the appearance of the night sky as seen from underwater. Species without this ability can form a symbiotic relationship with bioluminescent bacteria or eat other organisms with relevant biochemicals.

Experts argue that nuclear war is more likely than is commonly believed

The podcast highlights that many of the world's roughly 12,000 nuclear weapons—capable of triggering global collapse and nuclear winter—remain on high alert. Experts warn that this status, combined with limited public awareness, makes nuclear war disturbingly plausible.

Supervolcanoes can eject enough material to fill one-fourth of the Grand Canyon

Although extremely rare, their released material can trigger winters by blocking the sun and cooling the Earth’s surface for years. The Toba supereruption 74,000 years ago disrupted food chains and reduced the human population to a few thousand.
