Finding life beyond the Earth would be a major scientific discovery with significant implications for all areas of science and human thought. Yet, only one direct search for extraterrestrial life has ever been conducted.

At the eastern end of the Strand, opposite the Royal Courts of Justice, William Gladstone stands atop a plinth. Four times Queen Victoria’s Prime Minister, this eminent, emblematic Victorian is flanked by four female effigies testifying to the virtues of education, inspiration, courage, and brotherhood. Gladstone himself looks stately and solemn, as is fitting, but also mildly outraged, all clenched fists and frowns.

Well might he: he’s staring straight down what was, in his day, variously described as “a foul sink of iniquity”, “a place where dirt and darkness meet and make mortal compact” and, in the words of the Times, “the most vile street in the civilized world”. This was Holywell Street, the meridian of London’s booming pornography trade and, throughout the century, a byword for the dirty book trade long before Soho.

We highlight taxonomic misidentifications to show that coelacanth specimens from the British Rhaetian have been confused as far back as the late 1800s.

Numerous morphotypes of many bones in the sample hint at a complex community structure, with individuals of varying age, size, and likely several species, supported within the ecosystem.

The fossil occurrences suggest these Triassic coelacanths preferred shallow water environments, matching our observation that many specimens pertain to Mawsoniidae, a clade elsewhere reported from brackish, near-shore conditions.

In light of recent findings, the new specimens reinforce a European Triassic diversification for Mawsoniidae, which probably influenced their subsequent diversification and dispersion during the Jurassic.

These aren’t your everyday protons and neutrons; they are composite particles that hint at a richer, more intricate spectrum of matter dictated by the fundamental forces that govern reality. The journey into this exotic realm, led by a dedicated team of physicists, promises to revolutionize our perception of how quarks can combine, potentially rewriting chapters in the physics textbooks we’ve relied on for decades.

The Pc states, discovered a few years ago, immediately presented a tantalizing puzzle to the particle physics community. Unlike the well-established mesons and baryons, these particles appear to be composed of five quarks – a configuration that, according to the simplest models, should either be unstable or not form at all. The implications of their existence are profound, suggesting that the strong nuclear force, the glue that binds quarks together, can operate in ways far more sophisticated than previously understood. Imagine a Lego structure built not just with two or four bricks, but with an unexpected and seemingly improbable five. This is the kind of conceptual leap we are talking about.

The first interstellar object to visit the solar system may have been a fragment of an icy exoplanet, research suggests.

Everything about this object is consistent with it being a slab of nitrogen ice like you see on the surface of Pluto.

Instead of being a mix of water ice, rock and carbon-rich material left over from the formation of the solar system, 'Oumuamua appears to be almost pure nitrogen ice. And rather than being a compact ball, the visitor is more elongated than any known body in the solar system and starkly different from the interstellar Comets 2I/Borisov and 3I/ATLAS, the only other known interstellar visitors.

Is there a scientific reason why the universe exists? In other words, what is the science of why there is anything at all, instead of only nothing?

The answer has to do with opposites. Scientists have found that the universe exists because it began with a slight imbalance between matter and antimatter. Particles of matter — that is, all of the electrons, protons and neutrons in the atoms and molecules of regular stuff — differ from particles of antimatter, which carry the opposite electric charge but are similar in many ways.

Matter and antimatter do not get along. When their particles collide, they annihilate each other in an intense burst of gamma-rays. Fortunately, antimatter is now extremely rare. Although antimatter had a foundational role in the formation of the universe, the fact that there is now so little of it is one of cosmology's great mysteries.

This digest covers UFO and UAP-related developments from August 31, 2025 to September 6, 2025, summarizing key reports, sightings, disclosures, investigations, and policy responses from across the globe.

Key Takeaways

This week’s events reinforce growing institutional and public interest in the systematic monitoring, investigation, and disclosure of anomalous aerial phenomena. Government-led inquiries, sensor-based evidence, and legislative discussions continue to shape how the UFO/UAP topic is handled globally.

A universe full of white dwarfs

A white dwarf has about half the mass of the Sun, but that mass is compressed into a volume roughly the size of Earth, with its electrons pressed as close together as the laws of physics will allow. The sun has a radius 109 times the size of Earth's – this size difference means that an Earth-like planet orbiting a white dwarf could be about the same size as the star itself.

White dwarfs are extremely common: An estimated 10 billion of them exist in our galaxy. And since every low-mass star is destined to eventually become a white dwarf, countless more have yet to form. If it turns out that life can exist on planets orbiting white dwarfs, these stellar remnants could become promising and plentiful targets in the search for life beyond Earth.

But can life even exist on a planet orbiting a white dwarf? Astronomers have known since 2011 that the habitable zone is extremely close to the white dwarf. This zone is the location in a planetary system where liquid water could exist on a planet’s surface. It can’t be too close to the star that the water would boil, nor so far away that it would freeze.

The habitable zone around a white dwarf would be 10 to 100 times closer to the white dwarf than our own habitable zone is to our Sun, since white dwarfs are so much fainter.

It could be a legendary version of Etemenanki, a Mesopotamian ziggurat built to honor the god Marduk at such a scale that it inspired tall tales, as it were, spread far and wide in the ancient world, such as the rumor that its construction required mobilizing the manpower of all humanity. But it really did exist, as evidenced by its ruins discovered at the site of the ancient city of Babylon — which, in Hebrew, was called Babel.

Here, we present archaeobotanical data for ancient barley grains in association with sickle blades and grinding stones from the cave of Toda in the foothills of southern Uzbekistan.

This finding helps shed light on one of the greatest mysteries in central Asian archaeology—how did the Kelteminar people live?

We complement our data with a suite of radiocarbon dates, a detailed palynological study, an analysis of wood charcoal remains, and a detailed analysis of all aspects of the archaeological remains.

These data, collectively, paint the clearest picture thus far of the prehistory of this poorly studied corner of the ancient world.

Astronomers have captured a stunning image of a tail growing on interstellar invader Comet 3I/ATLAS. The image was captured on Aug. 27, 2025, by a team of scientists and students using the Gemini South telescope located on Cerro Pachón in Chile.

All of these objects offer scientists a unique opportunity to study material from another planetary system, and the growing tail of 3I/ATLAS is a tantalizing glimpse at the material that lies within this comet. But this opportunity is limited; as happened with 'Oumuamua and 2I/Borisov, 3I/ATLAS' orbit will eventually carry out of the solar system.
