  • Invention of optical instrumentsplugin-autotooltip__plain plugin-autotooltip_bigInvention of optical instruments

    The invention of the telescope and microscope are usually cited as being around the early 1600s.

    But sophisticated lenses, easily accurate enough for use in such instruments were being made far earlier. It seems highly unlikely that during a period of at least 500 years, no-one would have thought of putting two or more lenses together to form an optical instrument of some kind.
  • Effort gruntingplugin-autotooltip__plain plugin-autotooltip_bigEffort grunting

    An 'Effort Grunt' is the name given to the short gruff exhalation noises which people often make when exerting themselves.

    The noises are not restricted to humans, and are heard in many other primate species (ref. ) - suggesting an early evolutionary trait.
  • 'Lost' cometsplugin-autotooltip__plain plugin-autotooltip_big'Lost' comets

    It's usually possible to compute (with good accuracy) the paths of Solar System comets from observational data. Sometimes, however, they don't behave as expected, and are classified as 'lost'.

    There are a number of reasons why a comet might not adhere to its previously calculated path :
  • Musicogenic seizuresplugin-autotooltip__plain plugin-autotooltip_bigMusicogenic seizures

    A Musicogenic Seizure is a rare medical condition featuring epileptic-like seizures after exposure to music.

    The seizures can be immediate, or delayed by a few minutes after heaing music - occasionally hours.

    The mainstream current viewpoint is that the condition may be associated with a strong emotional response to the music rather than the musical sounds themselves. And that these emotional responses somehow cause adverse bio-chemical and/or bio-electrical changes in th…
  • The Folkton Drumsplugin-autotooltip__plain plugin-autotooltip_bigThe Folkton Drums

    The Folkton Drums are decorated solid chalk 'drums' form the neolithic period, The first example was found in 1889 in the northern UK, and since then others have been unearthed in the south. All are now in the British Museum. ( ref. with photos )

    Note: This article is currently in the 'proposed content' section.

    Several brands of toothpaste attempt to desensitize exposed dentine (see Dentin hypersensitivity). They typically use potassium nitrate, potassium chloride or potassium citrate. They can be an effective 'home treatment' - but the 'mechanism of action' has not been definitively confirmed

  • Southwest Paleohispanic Scriptplugin-autotooltip__plain plugin-autotooltip_bigSouthwest Paleohispanic Script

    Southwest Paleohispanic Scripts ( a.k.a. South-Lusitanian, Tartessian or Bastulo-Tartessian scripts ) are a set of undeciphered engravings - in an unknown language - that have been discovered in the south of Portugal, mainly Algarve and southern Alentejo. There are 90 or so individual examples on stone and pottery.
  • Electrical activity in fungiplugin-autotooltip__plain plugin-autotooltip_bigElectrical activity in fungi

    It's been established that many species of fungi generate small electric potentials (c. 100 mV) in their webs of underground fibres.

    It's unknown what significance these electrical potentials may or may not have. Some research groups have suggested that they could form the basis of 'signals' between fungi - or even between the fungi and nearby plants.
  • Microsaccadesplugin-autotooltip__plain plugin-autotooltip_bigMicrosaccades

    Microsacaddes (lit. trans. 'tiny pulls') are very small involuntary eye movements that are ubiquitous in mammalian vision. They've been known-about and studied since the mid 1880s.

    When fixed on any particular scene, the eyes tend to rapidly and repeatedly 'scan' the scene over a tiny range of less than 1 degree of the visual field.
  • Acrochorda (skin tags)plugin-autotooltip__plain plugin-autotooltip_bigAcrochorda (skin tags)

    "Acrochordons are 1 mm to 1 cm (rarely giant sized) papules that may or may not have stems. Their color ranges from skin color to dark brown. Although acrochordon development has been associated type 2 diabetes mellitus (DM), glucose intolerance, hyperinsulinemia, obesity, pregnancy, acromegaly, aging, colonic polyps and genetic predisposition,
  • Aeroplanktonplugin-autotooltip__plain plugin-autotooltip_bigAeroplankton

    The atmosphere of Earth is permanently teeming with countless numbers of microscopic organisms - including :

    * bacteria * viruses * fungi * algae * archaea * yeasts * spores of mosses, ferns, fungi, etc etc. * ( and, in addition, raw DNA and RNA fragments )

  • Sleepplugin-autotooltip__plain plugin-autotooltip_bigSleep

    "The purposes and mechanisms of sleep are only partially clear and are the subject of intense research"

    Source Wikipedia"

    Although extensive research in humans and animals has shown unequivocally that sleep is essential, the reasons why it's required are as yet unknown. Long term sleep deprivation not only severely impairs cognitive and motor skills, it's now been shown that it can cause physical damage to brain structure - and, in extreme cases, irreversible damage.

  • Positron excessplugin-autotooltip__plain plugin-autotooltip_bigPositron excess

    A 'Positron Excess' in cosmic emissions from deep space have recently been logged by various observation satellites ( PAMELA, Fermi-LAT and AMS-02 ).

    As yet, there is no agreed explanation for the source of the positrons (i.e. 'anti' electrons ) in the numbers in which they are found.
  • Roman dodecahedraplugin-autotooltip__plain plugin-autotooltip_bigRoman dodecahedra

    The first Roman Dodecahedron was found in 1739. Since then, more than 100 more have been discovered across Europe. ( example with photo )

    As the name suggests, they are 12-sided objects - and are hollow, usually with circular holes on each pentagonal face. They are normally made from copper alloy (i.e. bronze like).
  • Dentin hypersensitivityplugin-autotooltip__plain plugin-autotooltip_bigDentin hypersensitivity

    "Dentin hypersensitivity (DH, DHS) is dental pain which is sharp in character and of short duration, arising from exposed dentin surfaces in response to stimuli, typically thermal, evaporative, tactile, osmotic, chemical or electrical; and which cannot be ascribed to any other dental disease.

  • Peto's paradoxplugin-autotooltip__plain plugin-autotooltip_bigPeto's paradox

    Peto's Paradox was introduced by the UK epidemiologist Richard Peto in 1977. It is still generally considered unsolved.

    Simply stated : All animal cells have the potential to turn cancerous. Large animals have many more cells, therefore larger animals should be subject to higher rates of cancer. But they're not. In mammals for example, the larger animals in general have broadly similar rates to the smaller ones.
