Microscope is an instrument used to see objects that are too small to be seen by the naked eye. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the way the instruments interact with a sample to create images, either by sending a beam of light or electrons to a sample in its optical path, or by scanning across, and a short distance from, the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses light to pass through a sample to produce an image. Other major types of microscopes are the fluorescence microscope, the electron microscope (both, the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscopes. — Wikipedia

Science
Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy.
Optical microscopy and electron microscopy involve the diffraction, reflection, or refraction of electromagnetic radiation/electron beams interacting with the specimen, and the collection of the scattered radiation or another signal in order to create an image. This process may be carried out by wide-field irradiation of the sample (for example standard light microscopy and transmission electron microscopy) or by scanning a fine beam over the sample (for example confocal laser scanning microscopy and scanning electron microscopy). Scanning probe microscopy involves the interaction of a scanning probe with the surface of the object of interest. The development of microscopy revolutionized biology, gave rise to the field of histology and so remains an essential technique in the life and physical sciences. — Wikipedia

- Successful fertilization requires careful...on November 26, 2021 at 6:00 pm
RIKEN researchers have shown how the genomic sorting that occurs during fertilization—the incorporation of genomic material from both parents and the elimination of excess maternal DNA from the egg—takes place in mice. If the same process occurs in humans, the finding could help to improve some assisted reproductive technologies.
- Thermoelectric crystal conductivity reaches a new...on November 26, 2021 at 3:38 pm
Just as a voltage difference can generate electric current, a temperature difference can generate a current flow in thermoelectric materials governed by its "Peltier conductivity" (P). Now, researchers from Japan demonstrate an unprecedented large P in a single crystal of Ta2PdSe6 that is 200 times larger than the maximum P commercially available, opening doors to new research avenues and revolutionizing modern electronics.

Researchers have imaged a major component in conjugation—the process bacteria use to share DNA with each other.
- Fluorescence lifetime imaging to study DNA...on November 24, 2021 at 4:40 pm
Optical imaging is useful to investigate the structure and function of cellular genomes, but it is nevertheless challenging to image the immensely convoluted and irregular compacted DNA polymer. In a new report now published on Nature, Light: Science & Applications, Svitlana M. Levchenko and a team of researchers in China, Poland, and the U.S., developed fluorescence life-time imaging (FLIM) to advance the genomic structure during DNA compaction. During the work, they used two mechanisms, […]
- Enhancing the workhorse: Artificial intelligence,...on November 24, 2021 at 4:00 pm
Since artificial intelligence pioneer Marvin Minsky patented the principle of confocal microscopy in 1957, it has become the workhorse standard in life science laboratories worldwide, due to its superior contrast over traditional wide-field microscopy. Yet confocal microscopes aren't perfect. They boost resolution by imaging just one, single, in-focus point at a time, so it can take quite a while to scan an entire, delicate biological sample, exposing it light dosages that can be toxic.
