A WWI war helmet outperformed modern gear in this study

Exploring World War I technology on the battlefield

Industrialization brought massive changes to warfare during the Great War. Newly-invented killing machines begat novel defense mechanisms, which, in turn spurred the development of even deadlier technologies. Nearly every aspect of what we would consider modern warfare debuted on World War I battlefields. Starting with soldiers on horseback carrying lances and ending in poison gas, machine guns, and aerial battles, this gallery shows the first tools of modern warfare.

John Riddell’s first helmet was adopted by college football teams in 1939

The early days of football were violent and there was little protection for players, especially their heads. When deaths became commonplace, John Riddell set out to invent a better way to protect football players. Eventually, the technology from Riddell’s helmets ended up on WWII battlefields.

Early excavations at Pompeii uncovered pristine gladiator helmets and armor, showing no signs of combat wear, which were likely used only in ceremonial processions. Many are now displayed at the National Archaeological Museum of Naples.

10 items that could have saved your life in the trenches

Soldiers settled into trenches to defend themselves against shrapnel and bullets, but weapons such as mustard gas crawled along the ground and settled in these low-lying areas. Here are 10 items that could have helped you survive the trenches, according to this article.

Repeated head injuries can lead to CTE and early dementia

Chronic traumatic encephalopathy is a progressive neurodegenerative disease caused by repeated trauma to the head. The condition has become a particular concern in sports like football and soccer, from youth to professional leagues, where repeated low-level concussive events are likely.

Resistance training is linked to better memory and cognitive function in older adults

Randomized control trials looking at structural neuroimaging and exercise suggest that resistance training in older adults induces structural brain changes that could reduce the risk of Alzheimer's Disease or mitigate its progression. The benefits have been documented when performed at least twice per week for at least six months.

Why human brains were bigger 3,000 years ago

Our modern civilisation may be the most advanced to ever exist on Earth, but around 100 generations ago, our ancestors had brains that were larger than our own.

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.

Brain death is a uniquely modern problem stemming from modern ventilators

Patients who would have once died from devastating brain injury can now live on a ventilator for a long period of time, creating ethical, medical, and legal dilemmas.

Santa Barbara divers helped innovate deepwater diving technology

Divers in the Santa Barbara channel innovated a more efficient type of diving helmet in the 1960s that used helium to allow for longer, deeper excursions for oil surveying, abalone collecting, and more. These innovators have since set the standard worldwide for military and industrial diving.

Early testing of the US Army's mixed reality headsets made soldiers perform worse

Soldiers involved in testing the Integrated Visual Augmentation System reported headaches, nausea, limited peripheral vision, and concerns about security due to the display backlighting, which could be viewed from hundreds of meters away. The difficulties led the Department of Defense to transfer the program's contract from Microsoft to Anduril Industries.

Medieval European winters were colder than ours, but peasants stayed warm

Medieval winters were colder than ours today while the continent was mired in the so-called Little Ice Age. Without modern technologies, peasants survived with simple, sometimes genius, solutions, including central, chimney-less fireplaces (vented by small, draftless vents) and decorative handwarmers.

Blindfolded people could identify objects by touch alone a week after encountering them

These touch memories are more complex and durable than previously thought. In research published in 2018, blindfolded volunteers touched over 150 household objects for about 10 seconds each, and afterward correctly identified the objects more than 90 percent of the time when presented with the object and a similar one. Participants still knew most of the objects a week later with about 85 percent accuracy. (Some users may experience a paywall.)

With no textbooks or antibiotics, this WWI surgeon pioneered facial reconstruction

New Zealand surgeon Dr. Harold Gillies made extraordinary advances in the field of reconstructive surgery during World War I and after. This 36-minute NPR podcast interviews historian Lindsey Fitzharris, author of Gillie's biography, The Facemaker, charting how the good doctor reconstructed the faces of numerous soldiers in an age before antibiotics and plastic surgery as we know it today.

After 25 people used virtual reality headsets to practice flying with virtual wings—flapping their arms—their visual cortex responded to the wings almost as if they were real arms, treating them as body parts.

See what loud noises do to inner ear hair cells

This animation illustrates how louder music can affect inner ear hair cells. Damage to these cells is generally considered permanent. Hearing protection like ear plugs can reduce the level of sound entering into the ear and help protect those cells.

Tinnitus is the most common compensated claim for US veterans

Since 2003, tinnitus has been the top-ranked compensated claim among US veterans. In 2024 alone, there were more than 3.2 million awards for tinnitus. (Some users may encounter a paywall.)

A World War I discovery about blocking ethylene, a plant hormone, now helps preserve our fruits

Listen to this in-depth podcast episode about discoveries that enabled fruits and vegetables to be preserved and appear fresh for months or longer and other scientific insights, including why iceberg lettuce was the salad staple people ate for most of the 20th century.

Ballistic experiments show that tardigrades are unlikely to be an alien species

Those fired from guns at speeds as high as 825 meters per second (1,845 mph) could be resuscitated after impact. Shock pressure from greater speeds tore apart the samples, suggesting they could not survive asteroid impacts if brought to Earth from outer space.

Metal fragments can create glowing rings when sand chips them off helicopter blades

The Kopp-Etchells effect—named after two soldiers who died in action in Afghanistan—may occur when kicked-up material shaves off fragments from a helicopter blade's abrasion strip. Due to a property called pyrophoricity, the fragments react with air and ignite, producing halos.
