Artificial lightning can improve the yield of shiitake mushroom growers

Researchers have found that shockwaves produced from lightning strikes homogenously break internal filaments called hyphae, transitioning the mushrooms from a vegetative growth to a fruiting phase. Repeated minor shocks near mushroom logs mimicked this effect.

Radio waves are used in broadcasting, weather radar, telecommunications, and GPS

Its ability to bend around obstacles and reflect off the ionosphere—an electrified layer of Earth's upper atmosphere—allows this type of light to travel long distances without damaging living things due to its low energy. MRI scanners, WiFi, and Bluetooth technologies are also applications of this form of light.

Wireless charging uses a magnetic field to move charged particles in a battery

Based on the concept of electromagnetic induction, when a compatible device is placed on a charging pad with correct alignment, the alternating current flowing through the pad creates a changing magnetic field. This magnetic field induces a current in the device, recharging the battery without a connecting wire.

Hacking the body for a future that didn't happen

Journalist Adi Robertson experimented with one of the most accessible biohacks: magnets. Having a tiny magnet in their right ring finger meant they could sense magnetic fields, attract small metal objects, and more. But magnets weaken over time, eroding this new sense. Such implants do more than offer a new way of interacting with the world, they also pose new complications, such as the inability to get an MRI.

During flights, cell phones can act like signal jammers as they search for service

When farther from cell towers, these devices expend more energy to emit more powerful signals, which can overwhelm any ground-based tower or radio telescope they fly past. Rather than protecting the flight, airplane mode conserves a cell phone's battery.

The history of many kitchen appliances involves unexpected discoveries and applications, including wartime radar turned hamster defroster and replacing an 'ice king' with heat-stealing boxes.

In 1898, Nikola Tesla wowed a crowd by controlling a boat with no visible connection

Some onlookers thought it was a trick, such a a monkey being inside the boat, rather than mind control or some other metaphysical phenomenon. In reality, Tesla was pioneering radio waves, proving wireless control was possible.

The history of many kitchen appliances involves unexpected discoveries and applications, including wartime radar turned hamster defroster and replacing an 'ice king' with heat-stealing boxes.

The applications and industrial uses of graphene, the single-atom-thick material

Shortly after its discovery in 2004, the strength, flexibility, optical properties, and conductivity of this thin layer of carbon atoms earned it the designation of a "wonder material," but breakthroughs in its use have taken decades of research. As of 2026, graphene-enhanced electronic sensors, optical microchips, concrete, and supercapacitors are available, though scale production challenges remain.

How spoiled meat helped uncover a bacterium that can survive the vacuum of space

When a can of ground beef and pork spoiled despite attempts to sterilize it with gamma radiation, researcher Arthur Anderson isolated the bacteria in the food and discovered Deinococcus radiodurans. The polyextremophile has since been found on the walls of nuclear reactors and overcomes radiation damage through highly optimized DNA repair mechanisms.

Scientists turn alchemists, transforming transform lead into gold

Fulfilling alchemists' dreams, scientists at the Large Hadron Collider (LHC) transmute lead into gold. While the 86 billion gold nuclei produced were short-lived, the experiment sheds light on how electromagnetic fields can play a critical role in nuclear transmutation.

Lasers have been used to create natural adhesives for paper

German researchers at four Fraunhofer institutes have developed a method to seal paper packaging using a carbon monoxide laser. Without the need for glue or plastic adhesives, the Papure project is expected to improve the recyclability of paper. (Some readers may experience a paywall.)

13 unconventional ways to stay cool during heat waves

While air conditioning is the default solution for many in a heat wave, it can get expensive while requiring the consumption of fossil fuel energy. So, how else can you stay cool during a heat wave? This list compiles some practical, at times quirky, suggestions, including an ice-pack-filled aubergine hat.

High-altitude kites can perform airborne collection of energy from high-speed winds

Winds at high altitude are stronger and more consistent than those near Earth's surface, where natural and artificial barriers disrupt airflow. Kites pulled by the wind can extend a tether like a yo-yo, creating electricity in an attached ground generator.

Old credit cards can be made into guitar picks, phone stands and more

Experts recommend always cutting through the chip and the card number when disposing of expired credit cards, as the magnetic strip, the chip, and the card number all contain information that thieves might be interested in.

Onion routing disguises internet traffic in layers resembling a nesting doll

Data is encrypted at least three times before being sent to a node—a server that can only decrypt one layer. Then, the underlying encrypted data is relayed to another node, and the process repeats until all layers are decrypted. Thousands of possible nodes make it extremely difficult to trace activity within the system.

LIGO boosts its signal sensitivity by manipulating quantum uncertainty

According to the uncertainty principle, the amplitude, or height of a wave's peak, and its phase—the point in time when the first peak is observed—are inversely linked. Based on the frequency of the gravitational waves of interest, scientists sacrifice precision in one optical property to reduce noise in another.

How fecal transplants work

A professor explains how podcasts built on radio's strengths

When podcasts were first produced in the early 2000s, they were often recordings of radio shows aimed at listeners who wanted to listen outside of the broadcast windows. Siobhan McHugh, an associate professor of journalism at Australia's University of Wollongong, argues that the form is built on radio's intimacy, amplifying the connection listeners feel with their favorite hosts.

The microplane zester, mortar and pestle, and other underrated kitchen tools

Eight chefs weigh in on the most helpful culinary tools they often don't see in people's kitchens. The very specific fish fork, for example, not only delicately moves fragile filets but can double as an olive or soft cheese server.

Watch Apple Watch cases be 3D printed from titanium powder

Apple Watch Ultra 3 cases are 3D printed entirely from recycled, aerospace-grade titanium powder using lasers to fuse particles. Over 400 metric tons of raw titanium were saved in 2025, with two watches fabricated from the same amount of raw material that would have previously been used to make one.
