The wealthiest 10% cause trillions in environmental damage each year

A new study puts a price tag on high-end consumption — and finds the US and EU bear a disproportionate share of responsibility.

  • The top 10% of consumers cause trillions of dollars in annual environmental damage, the study finds.
  • Consumers from the US and EU are overrepresented among the highest-impact group.
  • Researchers call for fiscal tools targeting luxury consumption, not just mass-market behaviour.

Earth's most hostile places, where survival is barely possible

From Death Valley to salt flats and ice caps, some places on Earth push human endurance to its limits — yet people keep returning to explore them.

  • Death Valley holds the temperature record: 56.7°C, set in 1913.
  • The Atacama Desert, Antarctica and the Danakil Depression rank among Earth's harshest environments.
  • Scientists study these sites for extremophiles and planetary modelling.

Astronomers pinpoint source of mysterious long-period radio signals in the Milky Way

A type of slow, repeating radio burst from inside our galaxy finally has a confirmed origin — a finding researchers are calling a potential Rosetta Stone for a whole class of cosmic phenomena.

  • Astronomers have located the source of slow, repeating radio bursts inside the Milky Way.
  • The signals may originate from neutron stars, white dwarfs, or a previously unknown compact object type.
  • Researchers compare the find to the Rosetta Stone, calling it a key to a new class of cosmic phenomena.

300-million-year-old fossils rewrite the history of land vertebrates

Newly discovered fossils of creatures resembling hatchling crocodiles challenge long-held assumptions about how aquatic vertebrates first conquered land.

  • Fossils 300 million years old are changing our understanding of how vertebrates moved onto land.
  • The creatures resemble hatchling crocodiles, pointing to unexpected diversity in early terrestrial life.
  • The new specimens contradict the classic model of vertebrate land colonisation.

Divers spots new 'walking shark' species off Papua New Guinea

The shark moves along the seafloor using its fins as limbs — a rare behaviour now documented in a previously unknown species.

  • A new walking shark species has been discovered in waters off Papua New Guinea.
  • The animal uses its pectoral and pelvic fins to move across the seafloor.
  • Researchers confirmed it is a distinct species, previously unknown to science.

"The Hum": the global low-frequency drone millions claim to hear

Researchers now suggest the persistent, low-pitched sound reported worldwide for decades may be an unrecognised form of tinnitus.

  • The Hum is a persistent low-frequency sound reported globally for at least five decades.
  • A new hypothesis links it to a low-frequency variant of tinnitus not yet clinically defined.
  • Seismic, industrial and biological theories have all been proposed but none confirmed.

Scientists find a hidden weakness in forever chemicals

PFAS compounds, notorious for their near-indestructible nature, have a structural flaw that researchers say could be key to breaking them down.

  • PFAS compounds persist indefinitely in the environment and human body without breaking down.
  • Researchers identified a molecular vulnerability that could, in principle, allow neutralisation.
  • Translating the finding into practical decontamination technology will take years of further work.

Inflammatory bowel disease mystery solved after 30 years

Scientists say they have uncovered the deep biological causes of a painful digestive condition that had resisted explanation for three decades.

  • Inflammatory bowel disease covers severe chronic conditions, including Crohn's disease and ulcerative colitis.
  • Researchers have identified the biological mechanisms behind the disease after three decades of study.
  • The discovery may pave the way for treatments that address the root cause, not just symptoms.

The world's first nuclear clock works. What it might detect

Physicists have demonstrated a clock that keeps time using an atomic nucleus rather than electrons — a breakthrough that could reveal a fifth fundamental force of nature.

  • The first nuclear clock uses the thorium-229 nucleus transition, not electrons.
  • It is potentially more precise than current atomic standards, less prone to electromagnetic interference.
  • It could detect variations in nature's constants and signs of a fifth fundamental force.
