Astronomers can map dark matter's inferred gravitational effects without knowing what it is. Here is the evidence and the search for its identity.

A family-tree match can reopen a cold case. It cannot establish guilt. This guide follows the forensic steps and the distinct UK rules.

Physicists at the National University of Singapore have created a lutetium-ion atomic clock described as the most accurate timekeeper ever built.

Its accuracy has been verified at the nineteenth digit, with an error equivalent to roughly one second over more than 260 billion years.

The breakthrough could influence the future definition of the second while opening new possibilities in gravity measurement, navigation and fundamental physics.

Scientists have created a landmark atlas of gene activity in the human brain using samples from almost 1,500 donors spanning infancy to extreme old age.

The project maps individual cell populations and molecular changes associated with ageing, Alzheimer’s disease and other neurological and psychiatric disorders.

It could give researchers a far more precise guide to where disease begins and which biological pathways deserve investigation.

Perseverance has revealed ancient water activity, intriguing chemistry and potential biosignatures. Explore the major habitability findings, including September 2026 research, and why none yet establishes life on Mars.

Ancient teeth from Sulawesi may reveal the earliest known habitual drug use. Discover how physical wear and chemical traces support the betel-nut interpretation, and what the evidence cannot tell us about prehistoric lives.

Sleep paralysis can make waking feel frighteningly unfamiliar. Explore how awareness, muscle control and dream-like perceptions overlap, why episodes do not automatically mean narcolepsy, and what the small treatment studies can actually establish.

Plastic-to-food research uses chemical breakdown and engineered microbes to produce new ingredients. Understand the conversion, the August conference evidence and why safety, nutrition and practical production must each be assessed separately.

Human heart regeneration research points to a natural cellular response, not complete repair. Understand what the mitosis study reports, why its dates matter and what would be needed to turn biological capacity into treatment.

UCLA’s experimental cord-blood T-cell platform tackles cancer recognition and manufacturing together. Learn why consistent batches matter, what off-the-shelf means in research, and why human outcomes remain the decisive test.

Injectable nanoantenna research offers an experimental approach to glioblastoma. Understand what laboratory and mouse studies can show, why patient-derived cells are not a patient trial, and what clinical translation still requires.

MIT’s ammonia-to-hydrogen research targets recovery and purification within a larger energy chain. Understand why a lower-temperature process is interesting and why materials, scale and upstream emissions still matter to its usefulness.

Animal studies can reveal real effects without establishing a benefit in people. Learn how models, outcomes, delivery and trial design shape the journey from promising experiments to evidence that can support treatment.

A new science headline can describe an older paper or a fresh interpretation. Learn to separate research dates, publication stages and independent confirmation using concrete examples from the current news cycle.

General anaesthesia alters nervous-system activity through known drug actions. Explore why unconsciousness, memory and movement differ, how clinicians monitor patients, and what remains unresolved about the loss and return of conscious experience.

The Antikythera mechanism encoded astronomical cycles in bronze gears. Discover how imaging and inscriptions reveal its functions, why reconstruction remains difficult, and what the ancient calculator does—and does not—show about lost technology.

Placebo and nocebo effects can shape symptoms without explaining every change after treatment. Explore controlled trials, expectations and the crucial difference between feeling better and altering an underlying disease process.

Prions are disease-associated protein forms that can promote further misfolding. Understand how they propagate, why classic and variant CJD differ, and why rare transmission routes should not be confused with everyday contagion.

Understand accumulated sleep loss, what recovery sleep may improve and why weekend catch-up is not a guaranteed reset, with careful distinctions between sleepiness, performance, research findings and persistent sleep problems.

Explore the link between sleep, dream reports and memory, including maze-learning research, the limits of causal claims and why personal dream meanings differ from a scientifically validated decoding system.
