Extraoral expression and characterization of bitter taste receptors in (Mexican tetra fish).

The chemical senses of olfaction and taste are well developed in fish and play a vital role in its various activities such as navigation, mate recognition, and food detection. The small teleost fish consists of interfertile river-dwelling and cave-dwelling populations, referred to as "surface fish" and "cavefish" respectively. An important anatomical feature of cavefish is the lack of eyes leading them to be referred to as blind fish and suggesting an enhanced functional role for other senses such as taste.

Development of a ghatti gum/poly (acrylic acid)/TiO hydrogel nanocomposite for malachite green adsorption from aqueous media: Statistical optimization using response surface methodology.

The primary goal of this study is to prepare and characterize a ghatti gum/poly(acrylic acid)/TiO (GG/poly(AA)/TiO) hydrogel nanocomposite for adsorption of the dye malachite green (MG) from the aqueous phase in a discontinuous system. A variety of approaches were used to investigate the structure, morphology, and thermomechanical characteristics of the synthesized hydrogel nanocomposite. Response surface methodology (RSM) was performed to analyze the impact of three processing parameters, namely adsorbent dosage, dye concentration, contact duration, and their interactions on MG dye adsorption capacity.

Evidence of Large Recoil Velocity from a Black Hole Merger Signal.

The final black hole left behind after a binary black hole merger can attain a recoil velocity, or a "kick," reaching values up to 5000  km/s. This phenomenon has important implications for gravitational wave astronomy, black hole formation scenarios, testing general relativity, and galaxy evolution. We consider the gravitational wave signal from the binary black hole merger GW200129_065458 (henceforth referred to as GW200129), which has been shown to exhibit strong evidence of orbital precession.

Synthesis of silver nanoparticles from red and green parts of the pistachio hulls and their various in-vitro biological activities.

In this study, synthesis of silver nanoparticles (AgNPs) was carried out utilizing the red and green parts of the pistachio hulls then their several biological activities were investigated.
