New TSRI study offers surprising twist on how life began on Earth Sep 30th, 2016 02:57 UTC, A new study led by scientists at The Scripps Research Institute (TSRI) offers a twist on a popular theory for how life on Earth began about four billion years ago. The study questions the “RNA world” hypothesis, a theory for how RNA molecules evolved ..

‘RNA World’ Hypothesis Questioned: Alternate Theory Of How Life Started Proposed by Scientists Sep 30th, 2016 01:00 UTC, – A group of scientists have presented an alternate theory of how life on Earth started about four billion years ago. The current the “RNA world” hypothesis, is based on the assumption that RNA molecules evolved to create proteins ..

Game theory research reveals fragility of common resources on 29th of Sep 2016, Credit: Purdue University photo/John Underwood The ongoing research harnesses the Nash equilibrium, developed by Nobel laureate John Nash, whose life was chronicled in the film “A Beautiful Mind,” and also applies “prospect theory,” which describes ..

Do Driverless Cars Favor Urban or Suburban Life? on 29th of Sep 2016, Here are two competing theories of how the coming transportation revolution could impact American life. Henry Grabar Henry Grabar is a staff writer for Slate’s Moneybox. One possibility is that easy mobility—driverless cars, on-demand deliveries, ..

New research undermines 'RNA world' of early evolution on 29th of Sep 2016, The theory holds water for a variety of reasons . It’s unlikely repair enzymes were around when the first life forms first emerged, which means there must have been some biochemical mechanism keeping DNA and RNA apart. Researchers believe their latest ..

New Theory on Origin of Life on Earth Questions 'RNA World' Hypothesis on 29th of Sep 2016, A new study from The Scripps Research Institute (TSRI) has offered a surprising twist of how life began on earth, questioning the likeability of the “RNA World” Hypothesis and proposing that DNA may have also existed when life began. According to the study ..

Team finds alternate theory for how life started on 29th of Sep 2016, For more than three decades, scientists have hypothesized that the origins of life on Earth can be traced back to a series of chemical reactions that gave rise to self-replicating RNA, and that RNA then went on to evolve to create proteins and DNA ..

The English word theory was derived from a technical term in Ancient Greek philosophy. The word theoria, , meant Quotation Quotations About This Subject Thoughts without content are empty, intuitions without concepts are blind. In theory there is no difference between theory and practice. In practice there is. An ounce of action is worth a ton of theory. It is theory that decides what can be observed. Socrates thought and so do I that the wisest theory about the gods is no theory at all. Some theories are good for nothing except to be argued about. In order to shake a hypothesis, it is sometimes not necessary to do anything more than push it as far as it will go. One must credit an ...
Life (cf. biota) is a characteristic that distinguishes objects that have signaling and self-sustaining processes (i.e., living organisms) from those that do not, either because such functions have ceased (death), or else because they lack such functions and are classified as inanimate. Biology is the science concerned with the study of life. nLiving organisms undergo metabolism, maintain homeostasis, possess a capacity to grow, respond to stimuli, reproduce and, through natural selection, adapt to their environment in successive generations. More complex living organisms can communicate through various means. A diverse array of living organisms (life forms) can be found in the biosphere on ...
