Transcranial ultrasound is an essential tool for monitoring patients with various neurological conditions. Although it is commonly used in a protocolized fashion in consultative studies, the brain has been overlooked in many protocols utilizing point-of-care ultrasound (PoCUS). This study proposes a PoCUS image acquisition protocol.

Periodic Classification of the Elements

The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

lncRNA - Long Non-coding RNAs

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)...

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.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human color vision is impressive. People with normal color vision can tell apart millions of individual hues. Most amazingly, this ability is achieved with fairly simple hardware. Part of the power of human color vision comes from a clever bit of engineering in the human brain. There, color perception relies on what is known as an 'opponent system.' This means that the presence of one kind of stimulus is treated as evidence for...
FAQs
Color provides an immediate visual cue for atom identity, allowing viewers to separate elements while examining a structure’s connectivity and spatial arrangement. When combined with the positions of spheres or other model features, these cues make it easier to interpret which atoms contribute to a molecule and how they are organized in three dimensions.
Element colors are conventions rather than fixed physical properties, so palettes may vary between modeling systems, educational materials, and graphics programs. The CPK scheme offers a common reference, but viewers should check the displayed legend or stated convention before interpreting a color, especially when comparing structures from different sources.
The color assignments retain their role as element identifiers in both formats, but the surrounding visual information changes. Ball-and-stick models emphasize connections and arrangement through visible bonds and separated atoms, whereas space-filling models emphasize the occupied molecular shape. Color therefore works with each representation to support composition and structural interpretation.
Begin by matching each displayed color with the model’s element key or stated palette. Then examine how the colored atoms are connected and arranged in space, using the model type to guide interpretation. This sequence helps distinguish composition from three-dimensional organization and supports clearer reading of molecular graphics.
A legend is especially important when presenting molecular graphics to an audience that may not know the selected palette or when comparing images created with different conventions. It identifies the colors assigned to elements and reduces ambiguity, helping readers interpret structural-analysis figures, simulations, and other chemical visualizations consistently.
In education, color supports rapid recognition of atoms while learners study molecular structures. In research, the same visual convention helps communicate structural-analysis results, simulation outputs, and molecular or reaction data. Its value lies in making composition, connectivity, and three-dimensional arrangement easier to inspect and discuss across these chemistry contexts.
