Hidden craters suggest earth once had a Saturn-like ring

The rings of Saturn are some of the most famous and spectacular objects in the Solar System. Earth may once have had something similar. In a paper published last week in Earth & Planetary Science Letters, my colleagues and I present evidence that Earth may have had a ring. The existence of such a ring, forming around…

Exceptional new fish fossil sparks rethink of how earth’s geology drives evolution

Coelacanths are deep-sea fish that live off the coasts of southern Africa and Indonesia and can reach up to two metres in length. For a long time, scientists believed they were extinct. In new research published in Nature Communications, we reveal the best-preserved coelacanth fossil ever found from the ancient period hundreds of millions of years ago…

How skuas, frigatebirds, and gulls are helping spread avian influenza

It’s not easy finding food at sea. Seabirds often stay aloft, scanning the churning waters for elusive prey. Most seabirds take fish, squid, or other prey from the first few metres of seawater. Scavenging is common. But there are other tactics. Frigatebirds, skuas, and gulls rely on the success of other seabirds. These large, strong…

How quantum computing can make large language models even better

In recent years, the landscape of artificial intelligence (AI), particularly within the realm of natural language processing (NLP), has undergone a remarkable transformation. We have witnessed the rise of powerful large language models (LLMs) made by OpenAI, Google, and Microsoft, among others, and generative AI (Gen-AI), characterised by its unparalleled ability to generate data based…

New research rescues the dodo’s reputation from confusion and myth

The moment you hear the words “extinct” and “bird”, the dodo is probably the first creature on your mind, probably from an image in a school textbook you knew from years ago. The dodo’s significance transcended the boundaries of natural history. It has entered popular culture, immortalised in literature as a whimsical character with a…
