In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Reaching for objects, walking without hitting obstacles, landing on a chair as you sit (instead of falling to the floor), these and all our physical actions depend on an ability to perceive our own bodies in space, to know where our limbs are relative to one another and relative to the rest of the world. One way that the human brain encodes this information is called proprioception, the brain relies on its own control and feedback...

We present three new methods to study gustatory coding. Using a simple animal, the moth Manduca sexta (Manduca), we describe a dissection protocol, the use of extracellular tetrodes to record the activity of multiple gustatory receptor neurons, and a system for delivering and monitoring precisely timed pulses of tastants.

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms. Hand washing...
FAQs
A predefined coding scheme establishes which behavioral events to identify and how to classify their characteristics. Applying the same categories across videos, transcripts, field notes, or other observations makes records more comparable. This consistency helps researchers examine patterns rather than allowing changing labels or personal interpretations to determine the apparent results.
Manual observation is especially valuable when a behavior depends on context, unfolds through an interaction, or appears subtle in a recording or transcript. A human coder can use surrounding events and situational information when assigning a category. This flexibility complements automated systems and makes hand-coded observations useful for capturing details those systems may overlook.
Training helps coders apply category boundaries in the same way, while reliability checks assess whether their records agree sufficiently. Together, these practices make the coding process more dependable and help reveal ambiguity in the scheme. In behavior research, that quality control strengthens interpretation by showing that observed patterns are not solely products of one coder's judgment.
Timestamps and structured data sheets convert observations into organized records of when events occur and how they relate to one another. They can preserve sequence, frequency, duration, and interaction patterns for later comparison. This structure allows behavioral analysis to move beyond narrative description while retaining information about the timing and organization of conduct.
A practical workflow begins by setting the coding categories, reviewing the selected videos, transcripts, field notes, or other data, and recording each relevant event with its characteristics. Researchers can then organize the entries by timestamps or on structured data sheets, examine recurring patterns, and apply training and reliability checks before interpreting the results.
Hand-coded observations can provide data for testing behavioral hypotheses and for checking whether computational coding methods identify the same events and characteristics. Because manual records preserve context-dependent details, they can serve as a comparison point when evaluating automated approaches. The results also help connect computational outputs with interpretable behavioral patterns.
