Blue light is not the main cause of insomnia after all

Recent research overturns a decade-old belief: it is not the light from screens that disrupts sleep, but how and what we watch.

  • Blue light from screens has only a modest effect on sleep, contrary to popular belief.
  • Cognitive and emotional stimulation from content viewed is a stronger sleep disruptor.
  • Blue light filters do not fix insomnia if screen habits remain unchanged.

What heart rate variability reveals about your health

HRV — the time gap between heartbeats — is gaining traction as a marker of stress, recovery and the pace of biological ageing.

  • HRV tracks time variations between heartbeats, not overall heart rate.
  • A higher HRV signals better stress adaptation and faster recovery.
  • Consumer wearables have moved HRV from research labs into everyday use.

Carbon removal tech must scale at unprecedented speed to hold 1.5°C

Experts warn that carbon dioxide removal technologies are far behind the pace required to keep global warming within the Paris Agreement's upper safety limit.

  • The Paris Agreement's 1.5°C limit is at risk without active CO₂ removal, experts warn.
  • Current carbon removal technologies are well below the scale needed to meet climate targets.
  • Both biological and industrial capture methods are considered essential, not optional.

New supernova study confirms: the Universe is still accelerating

Researchers analysed fresh supernova data and dismissed an alternative theory that emerged in late 2025 questioning the standard cosmological model.

  • A new supernova study rejects the theory that challenged the acceleration of cosmic expansion.
  • Type Ia supernovae, used as cosmic distance markers, support the standard cosmological model.
  • Dark energy remains the leading explanation, though its precise nature is still unresolved.

Youth perfectionism hits an all-time high, study warns

Research spanning over 82,000 students across three countries finds unprecedented pressure on young people to be flawless.

  • The study covers more than 82,000 students across the US, Canada and the UK.
  • All three forms of perfectionism — self-, other- and socially prescribed — have increased.
  • The phenomenon is linked to anxiety, burnout and lower academic performance.

Chimpanzees reject unfairness more strongly when close allies are watching

A new study finds that chimpanzees' sensitivity to inequity intensifies in the presence of trusted partners — mirroring a deeply human social dynamic.

  • Chimpanzees refuse smaller rewards than those given to partners for equal effort.
  • The protest response intensifies when the favoured partner is a close social ally.
  • The study points to shared evolutionary roots for the sense of fairness in humans and chimpanzees.

Spacetime crystals could give rise to microscopic black holes

By extending general relativity into higher dimensions, three physicists have mathematically shown that repeating ripples in spacetime geometry can produce naked singularities and tiny black holes.

  • Repeating ripples in spacetime geometry can mathematically generate microscopic black holes.
  • The naked singularities found challenge Penrose's classical cosmic censorship conjecture.
  • The result is a mathematical demonstration only, with no observational confirmation yet.

British experimental drug makes tumours visible to the immune system

A compound developed in the UK has shown early promise across six cancer types by stripping away the camouflage that lets tumours evade immune detection.

  • The experimental compound makes tumour cells detectable by the patient's own immune system.
  • Preliminary positive results were recorded across six different types of cancer.
  • The drug targets patients with advanced disease resistant to standard immunotherapies.

2,000-year-old grape seeds rewrite the history of Roman wine

DNA extracted from ancient Tuscan wells reveals that Roman viticulture was far more organised and sophisticated than previously thought.

  • DNA from 2,000-year-old Tuscan seeds yields the most complete genetic profile of Roman grapevines from a single site.
  • Romans cultivated deliberately selected varieties within an organised agricultural network, not by chance.
  • Some ancient varieties may be direct ancestors of grapevines still grown across Europe today.

Scientists map a fan-shaped network of 30 basins buried under East Antarctica

Geophysicist Egidio Armadillo of the University of Genoa led the team that identified the vast interconnected structure hidden beneath the ice sheet.

  • A University of Genoa team discovered a system of ~30 interconnected basins under East Antarctica.
  • The fan-shaped structure extends across a vast area beneath the ice sheet.
  • The find could reshape understanding of subglacial water dynamics and ice-sheet stability.
