In the fight against climate change, solar power is a promising alternative to fossil fuels. Every second, Earth receives an enormous amount of energy from the sun. Yet solar cells capture only a fraction of it, constrained ...

Critical minerals such as those used in lithium-ion batteries come in limited supply and are concentrated in specific regions around the world. Securing a reliable supply of these materials is a priority for governments worldwide, ...

An international research team has reported an artificial nociceptor system that captures the temperature-dependent threshold modulation of biological nociceptors. Published in Advanced Functional Materials under the title ...

New research from the University of St Andrews reports sperm whales headbutting one another. The behavior was captured on film and described scientifically for the first time, confirming accounts by 19th century mariners ...

Rice is a vital crop that feeds more than half of the world's population. In the wild, many rice species are perennials that live for several years, but the varieties we eat today are typically annuals that must be replanted ...

Researchers leading a trial of active surveillance for ductal carcinoma in situ (DCIS) have described early results as "reassuring" in a presentation at the 15th European Breast Cancer Conference (EBCC15) in Barcelona.

Global maternal deaths have declined over the past three decades, yet progress has slowed in recent years and remains uneven across countries, according to new Global Burden of Disease (GBD) 2023 research published in The ...

For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979. On March 15, Arctic sea ice extent reached 5.52 million square ...

Research appearing in Communications Materials has shown that perovskite solar cells (PSCs) are remarkably resilient to dust during production, challenging the industry belief that high-performance solar technology must be ...

The soil beneath our feet is a huge carbon bank storing up to approximately three times more carbon than the entire atmosphere. That makes it a significant player in the future of our climate. If even a small fraction of ...

Earth's magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new international study has examined how a reduction of the magnetic field similar to the Laschamps excursion ...

Caltech scientists have developed a new way to produce optical frequency combs—important tools in devices that keep time and measure distances very precisely—at the chip scale, an advance that should make it easier to incorporate ...
