New archaeological discoveries challenge the classic "savanna hypothesis," suggesting early humans thrived in tropical forests far sooner than previously assumed.
New evidence places Homo sapiens in tropical forests hundreds of thousands of years earlier than thought.
The classic savanna-only hypothesis for human origins is being seriously questioned.
Ecological flexibility, not a single habitat, may be the key to our species' success.
Simulations published in Astronomy & Astrophysics suggest Earth could escape being swallowed when the Sun becomes a red giant — overturning the long-held consensus. Mercury and Venus won't be so lucky.
New simulations suggest Earth will not be swallowed when the Sun expands into a red giant.
Mercury and Venus face near-certain destruction; Earth's orbit may spare it.
The study, in Astronomy & Astrophysics, revises long-standing models of solar evolution.
Shelterbelts and hedgerows have long been seen as simple wins for nature, but new research suggests density and species mix matter just as much as planting itself.
Dense shelterbelts can undermine biodiversity rather than support it.
Species composition and planting density matter as much as the trees themselves.
Findings could reshape EU farmland afforestation policies if further validated.
New research proposes that the human body retains latent regenerative mechanisms capable of repairing damaged tissue — so far largely unexplored by medicine.
Humans may possess latent mechanisms for regenerating damaged tissue, researchers suggest.
The study offers a theoretical framework, not a clinical activation method.
Independent validation and further trials are needed before any medical application.
A team at Yonsei University developed lenses that deliver electrical signals through the retina to mood-regulating brain regions, with results matching a common antidepressant.
The lenses stimulate the retina electrically to influence mood-regulating brain circuits.
Effects observed in mice matched those of a commonly prescribed antidepressant.
The technology is non-invasive but remains in preclinical research stages.
Inbreeding didn't kill the Neanderthals, comet 3I/ATLAS is as old as the universe, and Max Planck's papers were mistakenly deleted by content algorithms.
A new study finds inbreeding was not responsible for the extinction of Neanderthals.
Interstellar comet 3I/ATLAS is estimated to be as old as the universe at roughly 13.8 billion years.
Automated algorithms mistakenly deleted Max Planck's scientific papers, raising alarms over academic archives.
Scientists propose that cosmic events — not just volcanoes or asteroid impacts — may lie behind the most devastating mass extinctions in Earth's history.
Cosmic events — supernovae, gamma-ray bursts — may have triggered mass extinctions on Earth.
The end-Permian extinction, the worst on record, wiped out over 90% of all species.
The hypothesis complements, rather than replaces, established extinction theories.
