The Arctic ground squirrel hibernates near death. Scientists want to replicate the trick

No other mammal survives such low body temperatures. Researchers are studying the mechanism to develop new treatments for heart attacks, strokes and brain injuries.

  • The Arctic ground squirrel survives hibernation at body temperatures close to freezing.
  • Its biological mechanisms could inspire treatments for heart attacks and strokes.
  • Researchers aim to replicate the squirrel's neuroprotection through pharmacology.

A well-preserved Byzantine city found in Egypt's Western Desert

The site, buried under desert sands for centuries, offers a rare glimpse into Byzantine urban life in North Africa.

  • A well-preserved Byzantine city has been discovered in Egypt's Western Desert.
  • Egypt's Byzantine period spans roughly the 4th to 7th centuries AD, before the Arab conquest.
  • Full excavation details are pending official publication by Egyptian heritage authorities.

Digital tool detects cancer patients at risk of severe immunotherapy side effects

Australian scientists have built a digital tool that quickly and accurately flags cancer patients likely to develop serious adverse reactions to immunotherapy.

  • Australian researchers built a digital tool to flag serious immunotherapy side effects early.
  • Immunotherapy is effective but causes severe adverse reactions in a subset of cancer patients.
  • Broader clinical validation will determine whether the tool enters standard oncology protocols.

Marigolds emerge as unlikely source of plant protein

A University of Georgia study finds that the common garden flower could have a role in the food industry as a vegetable protein source.

  • University of Georgia researchers found marigolds have a promising protein profile.
  • The plant's hardiness and availability make it a practical candidate for food use.
  • The study is preliminary; commercial applications require further testing.

ISS holds on, but its cracks can no longer be ignored

After 25 years in orbit, the International Space Station is accumulating structural defects for which no long-term fix exists.

  • The ISS is accumulating irreversible structural cracks, mainly in Russia's Zvezda module.
  • NASA plans to retire the station by 2030 and bring it down in a controlled Pacific splashdown.
  • Commercial successor stations are not on track to be operational in time for the handover.

Ancient asteroid impacts may have sparked the emergence of life on Earth

Scientists at the Southwest Research Institute argue that violent collisions in Earth's distant past could have created the chemical conditions needed for life to arise.

  • Asteroid impacts generated heat and pressure capable of synthesizing complex organic molecules.
  • SwRI researchers modeled in detail the chemical processes triggered by ancient collisions.
  • Asteroids are now a strong candidate in the scientific debate over the origin of life on Earth.

Who made the weapons that killed mammoths? Nobody knows

For decades, the Clovis culture was assumed to be North America's first great mammoth hunters. Researchers are no longer so certain.

  • The Clovis culture was long seen as North America's first major hunting civilization.
  • New research questions whether Clovis people were the sole makers of these lethal weapons.
  • The answer could rewrite the timeline of human settlement across the Americas.

Earth could remain habitable for another 1.8 billion years

A new scientific estimate pushes back the deadline for life on Earth, offering a more optimistic outlook than previous calculations.

  • Earth could support life for approximately another 1.8 billion years.
  • The limit is set by the Sun's increasing luminosity and the eventual loss of liquid water.
  • The estimate is significantly more optimistic than previous scientific models predicted.

Ancient human DNA extracted from cave paintings for the first time

Scientists have recovered human genetic material from prehistoric rock art pigments, opening a new path to identifying the artists behind Europe's cave paintings.

  • Ancient human DNA has been extracted for the first time from cave painting pigments.
  • The method expands archaeogenetics beyond bones and sediments.
  • Modern contamination risk remains the main technical challenge of the approach.

A fuel additive cuts diesel pollution by 60%

Researchers say a simple tweak to diesel fuel composition could slash harmful emissions without any changes to the engine itself.

  • Diesel pollution drops by over 60% through a change in fuel composition.
  • No engine modifications are needed, keeping adoption costs low.
  • Heavy transport is among the hardest sectors to decarbonize; this method could accelerate progress.
