Nature, the master engineer, is coming to our rescue again. Inspired by scorpions, scientists have created new pressure sensors that are both highly sensitive and able to work across a wide variety of pressures.

When temperatures get too hot to handle, most of us crank up the air conditioning to keep cool. It does the job, but it's expensive and uses a significant amount of energy. But now an innovation by scientists, primarily from ...

The ancient Japanese art of paper-folding, or origami, is already inspiring the design of the next generation of space vehicles, but now there's a new family of origami shapes that could make them even more compact and reliable.

Practical fusion power that can provide cheap, clean energy could be a step closer thanks to artificial intelligence. Scientists at Lawrence Livermore National Laboratory have developed a deep learning model that accurately ...

A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical potential) and the ohm ...

When maize fields become too crowded, the plants signal each other to boost their defenses. A research team led by Dongsheng Guo of Zhejiang University found that in crowded conditions, maize plants release a volatile gas ...

Researchers in China claim to have achieved a significant breakthrough in lithium battery technology, doubling the energy density (the amount of energy a battery can store relative to its size and weight) of Tesla's most ...

Gazing at smartphone screens for even one hour a day can cause digital eye strain, especially when scrolling through social media. According to a new study published in the Journal of Eye Movement Research, it is not just ...

Scientists from Virginia Tech have discovered a way to make ice move on its own. It's not a magic trick or a supernatural occurrence but a clever engineering feat. The team designed a flat metal surface that allows ice disks ...

Nature often puts on incredible displays. A recent example caught on camera shows thousands of bumblebee catfish (Rhyacoglanis paranensis) climbing waterfalls in southern Brazil. This is the first time the species has been ...

When we are out in cold weather, we wear warm clothes to stay comfortable. But there is a snag. Regular warm clothing can't adjust to changes in our body temperature. If we start to sweat, we get too hot and sticky, which ...

In the not-too-distant future, the search for signs of life on Mars and the moon could see the next generation of robots exploring a new frontier: subsurface lava tubes. These missions could also help us determine the best ...

Science frequently draws inspiration from the natural world. After all, nature has had billions of years to perfect its systems and processes. Taking their cue from mollusk catch muscles, researchers have developed a low-voltage, ...

Human waste usually gets flushed away, but instead of going down the toilet, it can help the planet and solve global fertilizer shortages, according to a new study published in the journal Proceedings of the National Academy ...

One of the most significant moments in the evolutionary journey of life on this planet was the transition from water to land. This huge step required animals to adapt to new challenges, including supporting their body weight ...
