Energetic shield
In fiction, this item consists of an invisible hull of force, meant to protect a certain body against weapons or elements by rejecting or absorbing their impact. The force field is projected onto the surface of or in the space around an object and works through absorption or reflection of an attack’s energy.
Can it be realized? It is debatable. Scientists take this possibility into account, however, there are a number of impediments to overcome. The issue would mean firstly projecting energy in a solid shape. The concerned costs would be enormous and the concept would go beyond the present technologic capacity. Efforts have been undertaken towards setting up protecting shields in case of spaceships which penetrate Earth’s magnetic field. They have regarded the production of a positively charged plasma cloud around the ship, which would prevent the sun’s positively charged particles from coming into contact with the ship’s steel structure. However, the exact developing status of the project is not known. Read the rest of this entry »

Interstellar travel
We have become familiar with the concept of interstellar travel by means of literature and science-fiction movies. It basically consists in the movement of a spatial vehicle through the galaxy at light speed over huge distances. This form of transportation is by far more complex than interplanetary travel, mainly due to the superior distances between stars. The possibility of managing such technology would allow the human race to reach new horizons and colonize faraway spaces of the galaxy.
Is it possible? NASA researchers believe so, as long as two major scientific conquests can take place: inventing a propulsion method which can allow reaching the maximum possible speed in the Universe and a new means of producing energy on board of the spaceship, which would give it indefinite sustenance and assure continuous functioning of all the devices. The issue of foodstuff resources is less discussed as human crew is not yet taken into account to be aboard the ship undertaking such a journey. Read the rest of this entry »

Computer expert Aubrey de Grey, author of the bestselling non-fiction “ Ending aging” is sure of having drawn, in his work, the theoretical basis of scientific conquests meant to allow people to control their biologic aging and live hundreds to thousands of years. Read the rest of this entry »

A
ccording to a new expertise, about half of American doctors regularly treat their patients by aid of the Placebo method. The process consists of the usage of medicine or vitamins which don’t actually help the ailing in their conditions to improve their help, relying exclusively on their power of suggestion to healing.
” It is an impressive discovery” says Franklin G. Miller, director of the ethical research program from the US National Institutes Health and one of the study’s authors.”Placebo has gone beyond the bounds of typical treatment in medicine with help of the sugar pill applied in experiments. Now, any treatment useless to the patient is a Placebo.” Scientists have known the Placebo effect for quite some time, procedure by which the patients are given a fake or inefficient treatment, which often improves their health state, only because they expect to get better.” Read the rest of this entry »

The close photograph of a faraway primordial galaxy has revealed that what was thought to be one single galaxy was actually made up of two, one of which incorporates black holes seemingly assimilating the other.
One of the two galaxies generates new stars while her twin seems to steal away their gas and dust. It is assumed that this way the two galaxies will entwine at some point. The clear image has been obtained by using the high-performance sub-millimeter radio telescope Array from Hawaii, which, unlike other telescopes, is able to perceive radio waves of a higher frequency and intercept carbon monoxide emissions which are peculiar to celestial bodies all over the universe.

An initial performance experiment has taken place in Berkshire, England, with the purpose of testing and recognizing intelligent thinking tendencies at robots. During the experiment, five robots have maintained free conversations for several minutes.
Researchers from Reading University have tested five machines in order to find out whether they would be able to pass for humans in the context of a basic conversation. The program was drafted in 1950 by British mathematician Alan Turing, who affirms that, if a machine may not be distinguished from a human being at this level, it can be considered capable of thinking.
Of five testes robots, only Elba has approached the minimum necessary level, attaining five points beneath the differential limit. However, none of the robots has passed the Turing test, which demanded that the robot should try and cheat on 30% of his human interlocutors in the context of a conversation.

Scientists have come to the conclusion that evolution is over in this age, at least in what regards Homo Sapiens. The future humans will look identical physically with the present ones, states a group of British researchers who have been studying this matter for a couple of years.
For centuries, scientists have been trying to imagine the aspect of the “ man of the future.” According to some, humans are destined to evolve into super-beings endowed with a range of paranormal abilities, while other scientists would imagine us developing into degenerated midget beings surrounded by screens and buttons, incapable of physical motion.
