bugün bunlarla geçti. sabah 10′dan akşam 17′e kadar uğraştık ama ortaya bir şey çıkmadı çünkü birisi mikroskopu kirletmiş ve temizlemeden gitmiş. bir de şu eldivenlerin 200 tanesi için 45 lira verdim, üniversitenin verdiği eldivenler elimden fırlayacak gibi emanet duruyordu. mecbur daha esnek eldiven almak zorunda kaldım. fotoğraflarda gördüğünüz şeyler ise agat kristalinden bir havanda şişe camlarına yaptığımız birkaç işlem sonrasında elde ettiklerimizi dövmek. günün yarısını havan döverek geçirdik diğer yarısı da işte mikroskopla uğraşıp görüntüler alarak geçti. sabah içtiğimden başka kahve içemedim, mal gibi dolanıyorum.

THANK YOU FOR AGREEING W MY BLORBO TAGS my brain is full of idiotic content for enstars and i need to study all of them under a microscope <333

and i am studying the microscope slides you prepare out of these characters because you are good at making the cross sections!!!! idk if this metaphor makes sense but the point is i am trying to convey enthusiasm<3

Eye of a locust

To achieve this result, you have to put a bit of transparent varnish on a dead locust's eye, then wait a minute until it dries, eventually take it delicately off with your nails.

These little hexagons are the surfaces of ommatidia, which are composed of photoreceptor cells and structure a compound eye. Each ommatidium has its cornea, crystalline cone — such as ours, except that they're thousands of them in a compound eye — photoreceptor cells and pigment cells, linked to an optic nerve.

Microscope

BY- K. Sai Manogna (MSIWM014)   The microscope is an instrument that creates enlarged photographs of small objects, enabling the viewer to display minute structures in a too near manner at a scale that is convenient for observation and study. Although optical microscopes are the focus of this article, many other types of wave, like acoustic, X-ray, or electron beam, can also enlarge the image…

A new method for fluorescence microscopy

- By Tokushima University -

Scientists have developed a fluorescence "lifetime" microscopy technique that uses frequency combs and no mechanical parts to observe dynamic biological phenomena.

Conventional fluorescence microscopy provides poor quantitative information of the sample because it only captures fluorescence intensity, which changes frequently and depends on external factors. Now, scientists from Japan have developed a new fluorescence microscopy technique to measure both fluorescence intensity and lifetime. Their method does not require mechanical scanning of a focal point; instead, it produces images from all points in the sample simultaneously, enabling a more quantitative study of dynamic biological and chemical processes.

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific wavelength range and then re-emit it at the longer wavelength range. However, the major limitation of conventional fluorescence microscopy techniques is that the results are very difficult to evaluate quantitatively; fluorescence intensity is significantly affected by both experimental conditions and the concentration of the fluorescent substance. Now, a new study by scientists from Japan is set to revolutionize the field of fluorescence lifetime microscopy.

A way around the conventional problem is to focus on fluorescence lifetime instead of intensity. When a fluorescent substance is irradiated with a short burst of light, the resulting fluorescence does not disappear immediately but actually “decays” over time in a way that is specific to that substance. The “fluorescence lifetime microscopy” technique leverages this phenomenon—which is independent of experimental conditions—to accurately quantify fluorescent molecules and changes in their environment. However, fluorescence decay is extremely fast, and ordinary cameras cannot capture it. While a single-point photodetector can be used instead, it has to be scanned throughout the sample’s area to be able to reconstruct a complete 2D picture from each measured point. This process involves movement of mechanical pieces, which greatly limits the speed of image capture.

Fortunately, in this recent study published in Science Advances, the aforementioned team of scientists developed a novel approach to acquire fluorescence lifetime images without necessitating mechanical scanning. Professor Takeshi Yasui, from Institute of Post-LED Photonics (pLED), Tokushima University, Japan, who led the study, explains, “Our method can be interpreted as simultaneously mapping 44,400 ‘light stopwatches’ over a 2D space to measure fluorescence lifetimes—all in a single shot and without scanning.” So, how was this achieved?

One of the main pillars of their method is the use of an optical frequency comb as the excitation light for the sample. An optical frequency comb is essentially a light signal composed of the sum of many discrete optical frequencies with a constant spacing in between them. The word “comb” in this context refers to how the signal looks when plotted against optical frequency: a dense cluster of equidistant “spikes” rising from the optical frequency axis and resembling a hair comb. Using special optical equipment, a pair of excitation frequency comb signals is decomposed into individual optical beat signals (dual-comb optical beats) with different intensity-modulation frequencies, each carrying a single modulation frequency, and irradiated on the target sample. The key here is that each light beam hits the sample on a spatially distinct location, creating a one-to-one correspondence between each point on the 2D surface of the sample (pixel) and each modulation frequency of the dual-comb optical beats.

Because of its fluorescence properties, the sample re-emits part of the captured radiation while still preserving the aforementioned frequency–position correspondence. The fluorescence emitted from the sample is then simply focused using a lens onto a high-speed single-point photodetector. Finally, the measured signal is mathematically transformed into the frequency domain, and the fluorescence lifetime at each “pixel” is easily calculated from the relative phase delay that exists between the excitation signal at that modulation frequency versus the one measured.

Thanks to its superior speed and high spatial resolution, the microscopy method developed in this study will make it easier to exploit the advantages of fluorescence lifetime measurements. “Because our technique does not require scanning, a simultaneous measurement over the entire sample is guaranteed in each shot,” remarks Prof. Yasui, “This will be helpful in life sciences where dynamic observations of living cells are needed.” In addition to providing deeper insight into biological processes, this new approach could be used for simultaneous imaging of multiple samples for antigen testing, which is already being used for the diagnosis of COVID-19.

Perhaps most importantly, this study showcases how optical frequency combs, which were only being used as “frequency rulers,” can find a place in microscopy techniques to push the envelope in life sciences. It holds promise for the development of novel therapeutic options to treat intractable diseases and enhance life expectancy, thereby benefitting the whole of humanity.

Guiding Sight

Your eyes look at the world but it's your brain that sees it. This is thanks to your optic nerve, which connects to nerve cells in the backs of your eyes (retina) to deliver their messages to your brain for interpretation. Development of the optic nerve involves the gene Dcc. Researchers now probe what Dcc is doing here using confocal microscopy (pictured) to image nerve cells in the eyes. In mutant mice lacking Dcc in their eyes, projections from nerve cells within the retina failed to connect up to the optic nerve (bottom) as occurs in normal mouse eyes (top, left). Instead, projections stalled or went in the opposite direction, similar to mutant mice lacking the protein, netrin, which is known to guide nerve cells (top, right). Dcc is therefore vital in properly wiring up the eyes to the brain.
