ሳይንስ እረጅናን ማቆም ይቻለው ይሆን?

እርጅና በዚች ምድረ ለመቀጠል ወይም ለመኖር እና ለመራባት አስፈላጊ የሆኑ አካላዊ ተግባራት  በጊዜ ሂደት ውስጥ መቀነስ ነው፡፡

እርጅናን ማቆም አይቻልም ነገር ግን ለማቆም ሳይንቲስቶች እየሰሩ መሆኑን ታውቋል፡፡

ሳይንቲስቶቸች እንደሚጠቁሙት እርጅናን ለማቆም ሚሥጥሩ ያለው ቴሎሜሬስ (telomeres) ላይ ነው፡፡ ቴሎሜሬስ የሚገኘው በኛ ክሮሞዞሞች ጫፍ ላይ ነው፡፡

ቴሎሜሬስ

  • ክሮመዞሙን ከጊዜዳ ጊዜ እየተበላሸ ከመምጣት ይታደገዋል ይጠብቀዋል
  • ርዝመታቸውም ምን ያህል ጊዜ እንደምንኖር ተፅኖ ያደርጋሉ

ፕሮጄሪያ (progeria) የተጠቁ ህፃናቶችን ቴሎሜሬስ ያጠኑ ዶክተሮች እንደተናገሩት በፕሮጄሪያ (progeria) የተጠቁ ሰዎች በጣም አጭር ቴሎሜሬስ ነው ያላቸው፡፡ ነገር ግን ዶክተሮቹ ቴሎሜሬሱን ረጅም ሲያደርጉት በፕሮጄሪያ (progeria) የተጠቁት ሴሎች ማርጀታቸውን አቁመዋል፡፡ እናም በእንዳንድ ሴሎች ላይ የነበርው እርጅና ሙሉ በሙሉ ማገገም ችሏል፡፡

ፕሮጄሪያ (progeria) ሶዎችን በቶሎ እንዲያረጁ የሚያደርግ ገዳይ በሽታ ነው፡፡ በፕሮጄሪያ (progeria) የተጠቁ ሰዎች ጎረምሳነት እንድሜያቸው የዘለለ ህይወት የላቸውም፡፡

ባጠቃለይ የተደረገው ጥናት ተደጋጋሚ ማጣራት ይፈልጋል ነገር ግን ጠናቱ እንዴት አንደምናረጅ ጠቋሚ ከመሆኑም በላይ የታመሙ ህፃናትን ለመርዳት ያገለግላል፡፡

አታርጁልኝ ብሎ ያስነበባችሁ ፡- Houston Methodist Research Institute Journal of the American College of Cardiology ጠቅሶ ያስነበበን የአለም ኢኮኖሚ ፎረም ነው

Cognizant of the major roles doctorate holders are said to have, the Ethiopian Science and Technology Information Center (STIC) conducted the study on doctorate holders residing within Ethiopia irrespective of their citizenship. Accordingly, they are expected to contribute to knowledge based economic growth and diffusion of innovation. Their role in science and technology is also believed to be vital. The study is principally based on the UNESCO manual, “Mapping Careers and Mobility of Doctorate Holders of 2012”. The central objectives include collecting internationally comparable statistics on their demographic and educational characteristics, employment situation, international mobility and contribution to R&D in Ethiopia. The second objective is assessing interdependency or association among some of the variables in the study. The results of the study woud have several significances. They would benefit policy makers as baseline for policy formulation. They would also help to draw the picture on the current situation of doctorate holders in the country. The target population of the study was doctorate holders below age 70. It involved 908 doctorate holders.

National Innovation Surveys


Innovation is quintessentially central to economic, environmental and social development. The planning and implementation of effective national innovation policy highly relays on reliable indicator reports. Innovation survey is one of the STI indicators that measure the state of innovation.

The results of the 2015, Ethiopian innovation survey conducted by the Ethiopian Science and Technology Information Center helps to better understand the level of innovation in the country and provided indicators for benchmarking national performance. Moreover, it provides informative data to policy makers in identifying innovation activities that have direct bearings on the performances of firms as well as factors that affect, motivate and influence their ability to innovate.
