An artist’s experimental approach to Rosalind Franklin’s Photo 51 reveals the molecule’s intricate biochemistry.
Tensions are rising as the ocean’s great predators nab fish on the line, inciting a major new challenge in human–wildlife conflict.
Cheap and fast algorithms are matching—and surpassing—the world’s top models
NuScale Power’s small modular reactors promised cheaper nuclear power, but costs soared and utilities balked
Verve Therapeutics says its base-editing approach may help prevent heart disease in many people
Europe’s earliest Homo sapiens seemed to have vanished without a genetic legacy — but genomic studies now show otherwise.
IBM’s NorthPole processor sidesteps need to access external memory, boosting computing power and saving energy.
A cell census provides information on the source of human brain specialization
The brain is composed of multiple regions associated with distinct functions, which have become further specialized in the human lineage. To define how this specialization is implemented, how it arises during development, and how it has emerged over the course of human evolution, a detailed understanding of the cells that make up the human brain is required.
Some whale populations are exhibiting unexpected cycles of boom and bust
The wastewater releas e from the Fukushima Daiichi nuclear plant is expected to have negligible effects on people and the ocean
In 2011, the east coast of Japan suffered an earthquake and tsunami that resulted in the meltdown of three of the reactors at the Fukushima Daiichi nuclear plant. This led to an uncontrolled release of large amounts of radioactive material to the surrounding land and to the Pacific Ocean.
A debate about the age of ancient footprints continues
Dating the oldest evidence for the presence of Homo sapiens in the Americas is a matter of ongoing debate. One view is that the earliest such evidence is from 16,000 to 14,000 years ago, after the Last Glacial Maximum (LGM), when people would have crossed the Beringian strait from Siberia over a dry land bridge.
The object’s deep red colour suggests it existed when the Universe was less than 700 million years old.
The James Webb Space Telescope (JWST) has seen what is probably a quasar from the early Universe1.
The Scopus, Dimensions and Web of Science databases are introducing conversational AI search.
The conversational AI-powered chatbots that have come to Internet search engines, such as Google’s Bard and Microsoft’s Bing, look increasingly set to change scientific search, too. On 1 August, Dutch publishing giant Elsevier released a ChatGPT-like artificial-intelligence (AI) interface for some users of its Scopus database, and British firm Digital Science announced a closed trial of an AI large language model (LLM) assistant for its Dimensions database. Meanwhile, US firm Clarivate says it’s working on bringing LLMs to its Web of Science database.
The huge eruption of the Hunga Tonga–Hunga Ha‘apai volcano generated more than 2,600 lightning flashes per minute.
Freely accessible large language models have accelerated the pace of innovation, computer scientists say.
The craze for generative artificial intelligence (AI) that began with the release of OpenAI’s ChatGPT shows no sign of abating. But while large technology companies such as OpenAI and Google have captured the attention of the wider public — and are finding ways to monetize their AI tools — a quieter revolution is being waged by researchers and software engineers at smaller organizations.
It also shows that restoring the integrity of the epigenome reverses age-related symptoms.

Two million year-old DNA found in frozen soil has been sequenced, revealing a surprising picture of an ancient landscape. Extinct creatures including, unexpectedly, elephant-like mastadons turn out to be among the beasts roaming Greenland. Researcher Eske Willerslev explains how DNA found in the environment can be used to reconstruct the past as so-called ‘eDNA’ becomes a vital tool for palaeontologists.
