The male Lady Amherst's pheasant knows how to put on a show when it comes to attracting mates. As well as elaborate courtship displays, they will unfurl their golden feathers to form a cape around their neck, which can prove ...

The quantum world is famously weird—a single particle can be in two places at once, its properties are undefined until they are measured, and the very act of measuring a quantum system changes everything. But according to ...

Earlier in 2025, Chinese solar manufacturer Longi announced it had built the world's most efficient solar cell. The hybrid interdigitated back-contact (HIBC) cell achieved 27.81% efficiency, which was verified by Germany's ...

Lemurs, the small primates with bushy tails and large, expressive eyes, are among the world's most endangered species. According to the IUCN (International Union for Conservation of Nature) Red List, of the 112 species of ...

Cancer is a common disease among mammals, but some species, such as the naked mole rat and elephants, have evolved resistance. According to new research published in the journal Science Advances, this may be because these ...

The Atlantic Meridional Overturning Circulation (AMOC), a system of Atlantic Ocean currents that redistributes heat and nutrients between the tropics and the North Atlantic, is one of the planet's tipping points. That means ...

Ulcerative colitis (UC) is one of the most common inflammatory bowel diseases, a lifelong condition that can cause chronic inflammation and ulcers in the lining of the large intestine. This can lead to symptoms such as rectal ...

While it is well known that climate change is heating the world's oceans, it was thought that the deep sea was safe from its effects—until now. Researchers have discovered that a rapidly warming part of the Atlantic is leading ...

When it comes to innovation, engineers have long proved to be brilliant copycats, drawing inspiration directly from nature. But now some scientists are moving beyond simple imitation to incorporating natural materials into ...

Trials of a new cholesterol-lowering pill have shown promising results for people with heterozygous familial hypercholesterolemia (HeFH), a genetic disorder that leads to high levels of LDL cholesterol.

A study of some of the first net-zero-ready homes in the UK has found that their peak grid power demand is far lower than planners had anticipated. The research confirms that these all-electric homes can significantly cut ...

A long-standing debate in paleontology about whether the distinctive Neanderthal nose evolved purely for the cold weather may have finally been solved, and it's all thanks to an ancient, exceptionally preserved nasal cavity.

Bipedal (two-legged) robots are sophisticated machines, but they are not the most graceful when things go wrong. A simple push, fall or an obstacle can send them crashing to the ground, often resulting in expensive damage ...

Using common kitchen ingredients such as citric acid and sodium bicarbonate, scientists have created an edible pneumatic battery and valve system to power soft robots.

In recent years, perovskite has emerged as a promising solution for cheaper, more efficient solar energy. This advanced synthetic material is made from crystals that mimic the naturally occurring crystal perovskite (calcium ...
