Stories about: amino-acids |

I think it's funny how studies conducted lately are beginning to indicate that it may be possible that life never originated on Earth in the first place. In tune with those discoveries, a new study shows that amino acids can survive an impact between Earth and a comet.
Now that this has been demonstrated, it i... |

The same basic molecules that form the basis of life here on Earth have been discovered in carbon-rich meteorites that fell to Earth from outer space. The finding appears to suggest that the basic building blocks of life permeate the Universe, waiting for the proper conditions to develop. The study was led by experts... |

An international team of investigators believes it may have discovered one of the possible birthplaces of life here on Earth. The research took the group to the mud volcanoes of Isua, in southwestern Greenland. The location fulfilled all necessary conditions to support the development of life.
The team was led by e... |

In a recent series of experiments, experts were able to demonstrate that the 20 amino-acids currently making up the basis of all lifeforms were not selected at random. Of the 100+ such molecules, this set proved to be the most efficient. This hints at the fact that life can arise on a whim on other worlds too.For yea... |

Ever since the first lifeforms developed on our planet, their basic components were founded on a specific group of 20 molecules in a group called amino-acids. A particular set of combinations made life possible here, but it could be that different amino-acids did the same on other worlds, experts say.The reason why t... |

Molecules without which life would have not appeared and developed on Earth appear to be produced in large quantities on asteroids. The space rock then spread their “products” via meteorites through solar systems, and on nearby planets. The same thing happened on Earth. Even now, molecules produced by the... |

According to a new iteration of an old experiment, it could be that the earliest life-forms that developed here on Earth smelled very, very bad. Experts came to this conclusion after analyzing the residues left behind by a study carried out by renowned expert Dr. Stanley Miller in the 1950s.In the groundbreaking inve... |

Scientists recently published the results of a new analysis, showing that the appearance life has here on Earth may be inscribed in the very laws of nature and reality. This, the team says, happens because of the way life is coded to emerge and develop, and also due to its basic components. A mathematical analysis of... |

According to a new scientific investigation, the key ingredients for the development of life may in fact appear in space, aboard meteorites and other wandering space rock. This conclusion was drawn after experts discovered basic molecules on a meteorite, in a place where they shouldn't have existed. It goes with... |

A team of researchers at the University of North Carolina (UNC) School of Medicine is currently working on a genetics research project of massive proportions. The team here is trying to determine how various “flavors” of histone are influencing our DNA.Inside the nucleus of each of our cells lie stra... |

Understanding how basic molecules called enantiomers form in their purest state could provide us with critically important new data about the origins of life on our planet, Spanish researchers say.A team there recently managed to conduct a new series of investigations on these molecules, which are basically one of tw... |

New computer models that simulated possible chemical reactions in Titan's atmosphere concluded that the basic organic molecules need to create life may exist on the largest moon of Saturn.The investigation basically states that carbon-based life forms are possible on the space object, which is one of the most in... |

A team of investigators at the University College Cork is finally shedding some more light on the reasons why bacterial infections that cause food poisoning are so unpredictable.The team says that the microorganisms have over millions of years of evolution adapted to a lifestyle that follows a single goal – boo... |

For the first time ever, researchers at the Rutgers University managed to shed light on a mechanism that ensures the quality of newly-produced proteins. Such a pathway is of tremendous importance for the good functioning of cellular life. The quality-control mechanism is especially important for yeast cells, which us... |

According to a new series of scientific investigations, it could be that the first molecules underlying the development of life on this planet did not appear here at all. These molecules have chiralities, as in spins, that are predominantly oriented towards the left side, although theoretically right-oriented ones sh... |

For many years, researchers have been trying to model the external and internal structure of proteins, small molecules that play an extremely important role in the human body. Scientists say that no less than 25 percent of all drugs currently approved for human consumption target a family of proteins called G pr... |

Over the years, many researchers have argued against the primordial soup theory, saying that the seeds of life on our planet may have arrived on Earth via meteorites. As recent studies have suggested, both the atmosphere and the oceans on our planet may be of extraterrestrial origin, and so this new idea for the emer... |

Some four decades ago, a large meteorite made its way to the Earth, in one of the rare instances in which such a descent was observed. The Murchison rock has since become one of the most studied on Earth, because it is relatively large, weighing more than 100 kilograms, and also because it apparently carries millions... |

One of the most famous asteroids was, for the scientific community, a space rock known as 2008 TC3, which was among the first to be scientifically observed as it entered the Earth's atmosphere, and burned down on descent. It was first spotted in 2008, and tracked until there was nothing left of it. Its surface a... |

Studying the particular molecular orientation, or the “handedness,” of organic molecules is one of the fields of study that hold the promise to answering one of humankind's basic questions, namely where we came from. For a long time, astronomers have known that certain celestial bodies, comets includ... |

Since it was shown in chemical experiments that the “primordial soup” could have led to the formation of complex proteins and nucleic acid strands from amino-acids over time, experts have been trying to model this in the laboratory, with various degrees of success. Now, German researchers at the Universit... |

For a long time, researchers have been fascinated with how complex life was able to evolve in the first place. From the primordial soup, a mix of amino-acids and basic RNA molecules, proteins, and eventually more complex structures developed, over millions and billions of years. Expert Stanley Miller was the first to... |

Over the past years, a significant portion of the international astronomical community has come to the conclusion that life on our planet must have originally come from comets. Of course, it is not talking about bacteria or other types of microorganisms, but about the chemicals that were needed for the initial reacti... |

Scientists from the University of Wisconsin-Madison (UWM) have recently announced the creation of synthetic protein-like mimics, which have the ability to stop unnecessary and unwanted chemical communication channels between cells. The new structures, created with a little help from molecular engineering techniques a... |

Growth factors, or cytokines, protein-signaling agents, are usually the way in which cells communicate with each other, or at least that's what researchers have believed until now. Just recently, a team of experts from the Massachusetts General Hospital Center for Engineering in Medicine (MGH-CEM) have managed t... |

According to a new scientific study conducted by investigators at the Hebrew University of Jerusalem, people react differently to stress, mostly on account of their genetic differences. Another important factor that generates varying responses to stressors (factors associated with stress) is the gender of a person. T... |
