અભિવ્યક્તિ એ ગુજરાતીઓનું અને ગુજરાતી જાણનારા ઓ નું પોતીકું છે. જેમાં આપણે સહુ આપણી માતૃભાષા માં ઉદ્ભવતી ઊર્મિ ઓ, કલ્પનાઓ, વિચારો ને અભિવ્યક્ત કરી શકવાની સ્વતંત્રતા ધરાવીએ છીએ. છતાં પણ અહીં અભિવ્યક્તિ ને ભાષા બંધનો નથી........
An Evolutionary Perspective of Weakening of Y Chromosomes through Male Attitude to Females Introduction The Y chromosome the marker defining masculinity is shrinking steadily. Having lost thousands of genes over millions of years, probably it will vanish someday, a prospect raising debates about how this may eventually affect males' physicals and behavior. Testosterone, a hormone under the control of male gonads, testes, is integral to all those traits considered by convention to be masculine and thus encompassing physical strength, competitiveness, and dominance. Weakened Y chromosome strength invites speculation about its influence on testosterone levels and how it may shape male behavior and roles in society as well as fitness in evolution. The weakening Y chromosome, testosterone, and male social behavior are related through the aspect of genetics, evolution and societal tendency. Weakening Y chromosome: This sex determinant has lost genetic material over millions of years. Oth...
K2-18b and the Mystery of Life’s Origins Hearing about K2-18b reignited my long-standing thoughts about the origin of life. I couldn't stop myself from expressing this excitement at such a meaningful moment. How lucky we are, and how fortunate our planet is, to be placed so perfectly at just the right distance from the Sun. Because of this precise positioning, Earth has been able to maintain an environment suitable for life. Our planet held onto its atmosphere, nurtured its oceans, and provided the conditions necessary for life to emerge. At the same time, Mars was not so lucky. It was severely affected by the powerful solar tides and the gravitational influence of Jupiter. Mars, once potentially capable of accommodating life, lost its atmosphere and became the barren desert we see today. Meanwhile, Earth survived and continued to evolve, creating a safe environment where life could grow and flourish. The origin of life on Earth happened gradually. Complex molecules began to form a...
