Earth has a new symmetry line: east and west hemispheres reflect sunlight equally

Scientists have identified an overlooked axis dividing the planet into eastern and western halves — revealing a surprising balance in Earth's reflectivity.

  • A new axis divides Earth into eastern and western hemispheres, separate from the classical ones.
  • Both hemispheres reflect approximately equal amounts of solar radiation into space.
  • The symmetry is surprising given the uneven distribution of land and oceans.

Earth's energy imbalance has doubled in two decades, scientists warn

A report by 74 researchers worldwide finds the planet is absorbing heat at an unprecedented rate, with the 1.5°C threshold potentially breached around 2030.

  • Earth's energy imbalance has more than doubled over two decades, hitting an all-time record.
  • The critical 1.5°C threshold above pre-industrial levels may be crossed around 2030.
  • 74 scientists: choices made this decade will define the pace of warming for generations.

Why Earth has no rings like Saturn

Saturn, Jupiter and Neptune all have ring systems. Earth does not. The reasons are rooted in physics, not coincidence.

  • Saturn, Jupiter, Uranus and Neptune have rings; Earth never accumulated stable orbital material.
  • The Moon's gravity disrupts any particles that might otherwise form a ring around Earth.
  • Planetary rings typically form from massive collisions or the break-up of a moon.

NASA defends all-male crew for Artemis 3 lunar mission

All four astronauts assigned to the Artemis 3 mission are men, prompting the agency's chief to publicly justify a selection once billed as a historic first for women.

  • NASA has assigned an all-male, four-person crew to the Artemis 3 lunar mission.
  • Agency leadership insists the selection was merit-based, not gender-driven.
  • Artemis 3 was originally presented as the mission to land the first woman on the Moon.

Four days of rain wiped out 7% of the world's rarest orangutans

A new study links an extreme rainfall event and landslides in Sumatra to the deaths of a significant share of an already critically endangered primate population.

  • Four days of rain and landslides in Sumatra killed 7% of the orangutan population.
  • Sumatran orangutans are among the rarest and most endangered primates on Earth.
  • Researchers warn extreme weather will increasingly threaten species already on the brink.

A fragment of a lost planet found in the Sahara Desert

The meteorite discovered in the desert may come from a planetary body destroyed in the early years of the Solar System, some 4.6 billion years ago.

  • The Saharan meteorite originates from an embryonic planet destroyed 4.6 billion years ago.
  • Its composition indicates a differentiated body with its own core, mantle and crust.
  • Such fragments are rare and provide direct insight into the formation of the Solar System.

A star exploded so completely it left no trace behind

Unlike typical supernovae, this stellar explosion produced neither a neutron star nor a black hole — a total annihilation with no cosmic remnant.

  • The star left behind no neutron star or black hole after its explosion.
  • The event confirms pair-instability supernova theory for extremely massive stars.
  • The finding offers clues about the chemical evolution of early-universe galaxies.

Hayabusa2 heads for an asteroid — and may find something unexpected

Japan's veteran space probe Hayabusa2 is closing in on a small, fast-spinning asteroid that could hold more surprises than scientists anticipate.

  • Hayabusa2, veteran of the Ryugu mission, is now targeting a small, rapidly spinning asteroid.
  • Fast-rotating asteroids may have unexpected internal structures and chemical compositions.
  • Findings could force revisions to current models of Solar System body formation.

Psilocybin tested in high doses as a potential dementia treatment

No drug has yet managed to stop or reverse dementia. Researchers are now exploring a psychedelic compound with early but promising results.

  • Psilocybin produced observable cognitive and behavioural effects in preliminary trials involving dementia patients.
  • The mechanism under study is neuroplasticity — the compound may stimulate the formation of new neural connections.
  • Trials remain small-scale; large randomised studies are required before any clinical application can be considered.

Physical punishment stunts school results and breeds aggression, study finds

A UCL study tracking nearly 19,000 British children finds that corporal punishment leaves lasting marks on academic performance and social behaviour.

  • UCL study of 19,000 children links physical punishment to lower exam scores.
  • Physically punished children show significantly higher aggression levels.
  • Effects are documented long-term, persisting well into adolescence.
