7,000 years of farming actually boosted plant biodiversity

A study on prehistoric Switzerland finds that traditional agriculture increased plant diversity for millennia — the collapse came only with industrial farming.

  • Swiss farming increased plant diversity for roughly 7,000 years.
  • Biodiversity decline began with the industrial intensification of agriculture.
  • The study suggests traditional practices could serve as a model for biodiversity recovery.

New study finds far more insects on Earth than previously estimated

Scientists have revised global insect population estimates upward, challenging decades of established calculations.

  • A new study suggests previous estimates of global insect numbers were significantly too low.
  • Updated calculation methods produced figures that exceeded scientific expectations.
  • The findings could reshape how researchers measure and interpret insect population decline.

Freud's century-old theory finds unexpected echoes in neuroscience

A study published in the journal Entropy draws structural parallels between Freudian psychoanalysis and the influential "predictive brain" model in contemporary neuroscience.

  • A study in Entropy compares psychoanalysis with the neuroscientific predictive brain model.
  • Freudian concepts such as the unconscious and repression can be reframed in computational terms.
  • The study has theoretical value only — it does not validate psychoanalysis as a therapy.

2.5 million years ago, a star passed close enough to trigger a comet shower

An unknown star swept through the Solar System's neighbourhood, close enough for its gravity to disturb the Oort Cloud and send comets raining inward.

  • An unidentified star passed near the Sun approximately 2.5 million years ago.
  • The flyby likely disturbed the Oort Cloud, sending comets toward the inner planets.
  • Gravitational effects from such stellar encounters can persist for millions of years.

The Antarctic volcano that dusts the atmosphere with gold

Mount Erebus has been releasing microscopic gold crystals into the air for decades — a phenomenon observed nowhere else on Earth and still not fully explained.

  • Mount Erebus releases an estimated 80 grams of microscopic gold particles into the air every day.
  • The phenomenon is unique on Earth and has been documented for more than three decades.
  • Particles spread over hundreds of kilometres but in concentrations far too low to be harvested.

Slow breathing reshapes the brain and influences decision-making

A study published in Neuron shows that conscious breathing control reprograms brain circuits and alters the choices we make.

  • A Neuron study shows slow breathing reprograms brain activity.
  • Circuits involved in decision-making are directly shaped by breathing rhythm.
  • The finding gives a neuroscientific basis to conscious breathing practices.

A lunar base as quarantine station for samples from space

Researchers argue that NASA's planned Moon base should act as a biosecurity checkpoint before any space material reaches Earth.

  • Researchers propose that NASA's lunar base also serve as a quarantine station for space samples.
  • The goal is to prevent potential extraterrestrial microbes from reaching Earth's biosphere.
  • The proposal comes as multiple sample-return missions are planned for the coming decade.

Study: AI systems reproduce age-related stereotypes

Researchers quantitatively analyzed responses from generative AI models and found systematic biases against certain age groups embedded in the outputs.

  • Researchers detected systematic age stereotypes in the responses of generative AI models.
  • AI replicates bias patterns from training texts without automatic correction.
  • Age bias remains less studied than gender or racial bias in AI research.

A rare supernova peeled a dying star and exposed its core

The blast stripped away the star's outer layers one by one, giving astronomers a direct look at how the universe forges the chemical elements that make up everything around us.

  • A rare stellar explosion exposed the internal layers of a dying star in sequence.
  • Observations confirm how massive stars produce heavy chemical elements.
  • The data allow direct testing of theoretical models of cosmic nucleosynthesis.

Scientists find the unexpected deep inside Yellowstone's supervolcano

A new study of the magmatic system beneath Yellowstone yields data that existing models had not predicted.

  • A new study on Yellowstone's magmatic reservoir has revealed unexpected structural characteristics.
  • Supereruptions can release over 1,000 km³ of volcanic material, with global climate impact.
  • The last supereruption at Yellowstone occurred roughly 640,000 years ago.
