The Wellcome Trust — a London - based medical inquiry Greek valerian — has just announced the success of its 2012 double competition , and they are positively sensational . Take the scanning electron micrograph feature above , for example . Can you guess the subject of the picture ? It may be the most widely consume psychotropic drug on Earth , but it reckon awfully unfamiliar at this level of detail .
Figure it out ? They ’re caffein crystal , throw together together into structures that measure just 40 micrometer in distance . ( As a point of address , 1 mm = 1,000 microns ) . conquer byAnnie Cavanaugh and David McCarthy , it ’s just one of this year ’s 16 winning images . We ’ve sport a handful of this year ’s best below , but you could contain out the relief ( via a coolheaded , interactive effigy drift ) atThe Wellcome Image Awards .
Chicken conceptus vascular system
Vincent Pasque / University of Cambridge
This fluorescence micrograph shows the vascular scheme of a developing wimp conceptus ( Gallus gallus ) , two days after fertilisation . Injecting fluorescent dextran revealed the entire vasculature used by the embryo to feed itself from the fat underlying vitellus inside the egg . At this microscope stage of development , the embryo and its surround vasculature are a little minor than a 5p coin .
Moth fly ( Psychodidae )
Kevin MacKenzie / University of Aberdeen
This sour - dark scanning negatron micrograph shows a moth fly ( Psychodidae ) , also known as a waste pipe tent flap . As its name suggests , the tent flap ’s larvae commonly live and grow in domesticated drains ; the grownup fly emerges near sinks , bathing tub and privy . The moth flies ’ bodies and wing are covered in tomentum , which gives them a ‘ bleary ’ , moth - like appearance . The fly is 4 - 5 mm long , and each eye is roughly 100 microns encompassing .
Diatom frustule
Anne Weston / London Research Institute
This put on - coloured scanning electron micrograph shows a diatom frustule . diatom are unicellular organisms and a major mathematical group of algae . Diatoms are incase within a knockout cell paries made from silica . Frustules have a variety of patterns , pores , pricker and ridges , which are used to determine genus and species . diatom are one of the most common types of phytoplankton , and their community are often used to measure environmental conditions such as water character . This diatom is more or less 80 microns in diameter .
Microneedle vaccine
Peter Demuth
This scanning electron micrograph shows an array of ‘ microneedles ’ made from a biodegradable polymer . Researchers have shown these material can be used to deliver vaccines and therapeutics to the out layer of the skin in a safe and painless style . Each microneedle is approximately 700 microns high and 250 microns blanket at the theme and can be utilise to the hide as a one centimetre - squared patch .
Cell division
Kuan - Chung Su and Mark Petronczki / London Research Institute
This composite confocal micrograph uses time - lapse microscopy to show a malignant neoplastic disease cell ( HeLa ) undergoing cell part ( mitosis ) . The deoxyribonucleic acid is shown in red , and the cadre tissue layer is shown in cyan . The round cellular telephone in the centre has a diameter of 20 microns .
Intracranial transcription for epilepsy
Robert Ludlow / UCL Institue of Neurology
This exposure read the surface ( cortex ) of a human brain belong to an epileptic affected role . The icon displays the bright crimson arteries that ply the brain with nutrients and oxygen and the imperial venous blood vessel that remove deoxygenate blood . This photograph was taken before an intracranial electrode recording routine for epilepsy , in which electrical activity is measured from the give away aerofoil of the learning ability .
