Stop counting sheep – and 13 more no-nonsense tips for getting back to sleep
Don’t count sheep Bad news for that old favourite, counting sheep. “It has been studied and it doesn’t work,” says Dr Eidn Mahmoudzadeh, a Manchester GP and co-founder of The Sleep Project, which offers support for sleeplessness at all ages. “It is too simple and mundane; people don’t carry on, they just get bored and their thoughts wander to worrying about sleep.” Counterintuitively, you should go for something more mentally challenging, he says, to distract the brain.

A Future Without Power Lines: America’s Successful Laser-Based Wireless Electricity Transmission
Imagine a world where the familiar sight of towering electricity poles and tangled power lines becomes a relic of the past. For over a century, our modern infrastructure has depended on overhead wires to deliver power to homes, industries, and cities. But now, a groundbreaking experiment in the United States is proving that electricity can travel invisibly—through beams of light in open air. This futuristic concept took a giant leap toward reality when America’s Defense Advanced Research Projects Agency (DARPA) announced a historic success. In a carefully designed test last month in the state of New Mexico, researchers transmitted 800 watts of power over a distance of 8.6 kilometers (approximately 5.3 miles) without a single wire connecting the source and receiver. Instead of copper cables or high-tension lines, DARPA used a high-powered laser beam to carry electricity across the desert. For 30 uninterrupted seconds, the system delivered enough power to operate essential equipment, setting a new record for the longest-distance, highest-energy laser-based wireless transmission to date. The implications of this achievement are profound. If perfected and scaled, laser power beaming could transform how we deliver electricity to remote locations, disaster zones, military operations, or even spacecraft and satellites. No longer would engineers have to build complex grid infrastructure across rugged terrain or rebuild power lines after hurricanes or earthquakes. Energy could simply be beamed through the air safely and efficiently. DARPA’s program, known as POWER (Persistent Optical Wireless Energy Relay), has been researching this technology for several years. The goal is to create a reliable system that can transmit power over long distances using laser beams aimed at special photovoltaic receivers, which convert the light back into electricity. This process is similar to how solar panels work, except instead of collecting sunlight, the panels absorb the focused laser energy. To achieve this latest milestone, engineers had to overcome significant challenges. First, transmitting such a high amount of energy without scattering or losing power required advanced laser optics and precise targeting systems. Even a slight misalignment could have caused the beam to miss the receiver entirely. Second, safety protocols had to be developed to ensure the powerful laser posed no threat to aircraft or unintended targets. During the New Mexico demonstration, DARPA’s team used automated tracking and adaptive optics to keep the beam steady across the 8.6-kilometer distance. Sophisticated sensors continuously monitored the beam’s alignment and environmental conditions such as heat shimmer, dust, and atmospheric turbulence, which could have degraded the signal. While the 800-watt transmission lasted only 30 seconds, it was enough to prove the concept at scale. Future experiments will focus on increasing the duration of power delivery and improving the system’s overall efficiency and reliability. One of the most exciting aspects of laser power beaming is its versatility. In the future, this technology could be used to send electricity to places that currently have no access to the grid—such as isolated villages, temporary camps, or disaster-stricken areas. Mobile receivers could be deployed rapidly, and energy could be transmitted without waiting months or years to build infrastructure. Space applications are also a major focus. NASA and other space agencies are exploring the possibility of beaming solar power collected by satellites down to Earth, providing a renewable energy source that works day and night. Similarly, spacecraft or lunar bases could be supplied with electricity without relying on heavy batteries or nuclear generators. Of course, many hurdles remain before laser power beaming can become part of everyday life. Engineers must develop safeguards to prevent accidental exposure to high-intensity beams, ensure the systems are resilient to weather, and scale production to make them cost-effective. But the success of DARPA’s demonstration is a powerful signal that this science-fiction dream is steadily becoming science fact. In the coming decades, electricity may no longer be something we pull from buried cables or overhead wires. Instead, it could arrive silently and invisibly—carried by focused light across vast distances. If this vision becomes reality, power poles and tangled lines could truly become relics of history.
