Discovery

Nowadays, many technologies have been developed to help arthritis sufferers.

Then, bioengineers at Rice University recently discovered a new technology : using intense pressure to stimulates cartilage cells to grow new tissue with nearly all of the properties of natural cartilage, that’s why it’s called tissue-engineering method. It was reported in the ScienceDaily that the new method will no need stem cells, well, this is the unique advantage point, in my opinion.

Lead researcher Kyriacos Athanasiou, Rice’s Karl F. Hasselmann Professor of Bioengineering mentioned that this technology is very promising not only for cartilage but also for tissues to repair bladders, blood vessels, kidneys, heart valves, bones and more.
Great job, Prof!

Contact lenses known can correct the vision of people with nearsightedness, farsightedness, and astigmatism. One in five people in America found to use contact lenses. For more than 100 years of its discovery, many advancements have been found, allowing just about everyone to wear contact lenses.

Seeing this, biomedical engineers at UC Davis collaborating with Department of Ophthalmology at the UC Davis School of Medicine, developing “Smart Contact Lenses”, that can measure pressure within the eye and dispense medication.

What makes it smart?

The contact lenses made with a pattern of conductive silver wires could be used to measure pressure inside the eye and study glaucoma, a major cause of blindness. The silver has antimicrobial properties!

Besides, the researchers developed a method for placing powdered silver on the PDMS in a precise pattern, to create conductive wires.

Our universe began with the Big Bang about 13 billion years ago, and that soon after that event, matter began to form as small dust grains and gases. This is what our researchers believe for years.

Recently, it was reported that researchers has taken the study of primordial star formation to a new level with a new simulation on how star came into universe, but it still gets them only to the halfway point towards the final goal. It is like laying the foundation of a skyscraper.

Further researches needed, that they must continue the studies to understand how the initially tiny protostar grows, layer by layer, to eventually form a massive star. But here, the physics become much more complicated and even more computational resources are needed.

Research on adult stem cells has recently generated a great deal of excitement. Scientists have found adult stem cells in many more tissues than they once thought possible.

An adult stem cell is an undifferentiated cell found among differentiated cells in a tissue or organ, can renew itself, and can differentiate to yield the major specialized cell types of the tissue or organ. The primary roles of adult stem cells in a living organism are to maintain and repair the tissue in which they are found. Some scientists now use the term somatic stem cell instead of adult stem cell. Unlike embryonic stem cells, which are defined by their origin (the inner cell mass of the blastocyst), the origin of adult stem cells in mature tissues is unknown.

Recently, adult stem cells originate in a different part of the brain than is commonly believed, and with proper stimulation they can produce new brain cells to replace those lost to disease or injury, a study by UC Irvine scientists has shown.

The development of stem cells technology have been well implemented, for it has the remarkable potential to develop into many different cell types in the body.

Now, for the first time, the world scientists have succeeded in developing human embryonic stem cells (hESCs) from a single cell, or blastomere, of a 4-cell stage embryo, ScienceDaily reported.

From the results, it might be possible in the future to produce (human embryonic stem cells) hESC lines at an earlier stage without destroying the embryo. In the mean time, other researchers are about arguing on this research for two reasons :

1). They believe that it is morally wrong to use embryonic stem cells for research, and
2).They believe that it is morally wrong to use embryonic stem cells for medical treatment.

It is known that when a stem cell divides, each new cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Recently, a team of UC San Diego scientists have isolated more than two dozen promising and novel compounds from which new “designer drugs” might be developed to combat this disease. In some cases, the compounds appeared to be equal or stronger inhibitors than currently available anti-flu remedies.

Rommie Amaro, a postdoctoral fellow in chemistry at UC San Diego, the leader of the researcher said, they have a prior work that captured the nanosecond-by-nanosecond movements of a protein called neuraminidase 1 (or N1), needed by the avian flu virus to spread infection to new cells.

Well, there are so much urgency to find drugs to combat this virus, let’s hope that the results will assist what we are expecting for.

The new technology can be widely used for poultry, meat and egg processing industries.

In modern life, drinking coffee has become a lifestyle. It is now playing an important role to our life.
Recently, a new study find that regular coffee drinking (up to 6 cups per day) is not associated with increased deaths in either men or women. In fact, both caffeinated and decaffeinated coffee consumption is associated with a somewhat smaller rate of death from heart disease.

Many people avoid coffee for it is intimately linked to caffeine content. Depending on the type of coffee and method of preparation, the caffeine content of a single serving can vary greatly. But Esther Lopez-Garcia, PhD, the study’s lead author said that, coffee consumption was not associated with a higher risk of mortality in middle-aged men and women. The possibility of a modest benefit of coffee consumption on heart disease, cancer, and other causes of death needs to be further investigated.

It was revealed in Science Daily that, in IBM’s labs, the researchers are about creating a design that promises to extend Moore’s Law into the next decade and significantly reduce the energy consumed by data centers.

How could it be ?

The scientist unveiled a powerful and efficient technique to cool 3-D chip stacks with water. These so-called 3-D chip stacks presents one of the most promising approaches to enhancing chip performance beyond its predicted limits.

The prototype has been demonstrated in collaboration with Fraunhofer Institute in Berlin.

Electro-gravitics research seeking the nature of gravity and its control has reached a stage where profound implications for the entire human race have emerged. Perhaps the most startling and immediate involve aircraft, guided missiles, atmospheric and deep space flights.

If only one line of research achieves the goal and it now seems plausible that this has already happened gravitational acceleration as a structural, aerodynamic and medical problem will cease to exist. So will the task of providing massive volumes of combustible fuels in order to escape the earth’s gravity, the biggest headache facing NASA engineers.

There are now gravity research projects in every major country of the world; in fact hundreds, are deeply involved in anti-gravity and anti-mass research, much of it funded by military and federal intelligence agencies. Some are over 70 years old. Some are much newer. A few, purely theoretical,
seek their answers in Quantum, Relativity and Unified Field Theory mathematics.

Some of these now secret projects, mostly empirical, investigate gravitic isotopes, electrical phenomena and the statistics of mass while others combine both approaches in the study of matter in its super-cooled, super-conductive state, jet electron streams, peculiar magnetic effects or the electrical mechanics of the atom.

The concept of weightlessness in normally heavy conventional materials like steel, aluminium, barium, etc., is difficult enough, but some theories, so far proven empirically in the laboratory, postulate that not only can they be made weightless, they can in fact be given a negative weight. That is: the force of gravity will repel them and, when dropped, they will fall upward into the sky!

In this particular line of research, the weights of some materials have already been cut as much as 30% by “energizing” them. Security precludes disclosure of what is meant by “energizing” or in which country this work is being conducted.

By 1956 a localized gravitic field used as a motive force was created in the laboratory. Disc airfoils two feet in diameter and incorporating a variation of the simple two-plate electrical condenser charged with fifty kilovolts and a total continuous energy input of fifty watts achieved a speed of seventeen feet per second in a circular air course twenty feet in diameter. Later the discs were increased in diameter to
three feet and run in a fifty-foot diameter air course under a charge of a hundred and fifty kilovolts with results so impressive that the project quickly acquired the highest classification and laboratories were moved, lock, stock and barrel, to hastily prepared and prodigiously funded underground facilities throughout the world.

Variations of this work done under a vacuum have produced efficiencies that can only be described as startling. Researchers immediately began to develop generators producing power up to fifteen million volts! Such a generator would drive a vehicle of enormous size into deep space at near light speed, a clear indication of the intent of governments in this research.

That generative force raised exponentially to levels capable of pushing man-carrying vehicles through the air or outer space at ultra high speeds soon became the object of special interest in several countries. If achieved it will eliminate most of the structural difficulties encountered in the construction of high-speed aircraft. Importantly, the gravitic field that provides the basic propulsive force simultaneously reacts on all matter within the field’s influence. The force is not a physical one acting initially at a specific point in the vehicle then to be translated to all the other parts. It is an electro-gravitic field acting on all parts simultaneously. The gravitic engine generates an anti-mass field when charged and, thus, eliminates inertial forces completely.

Subject only to the laws of momentum, the vehicles are able to change direction, accelerate to hundreds of thousands of miles per hour, or stop. Changes in direction and speed of flight are effected by merely altering the intensity, polarity and direction of the charge.

The communications possible using electro gravitics stagger the imagination. There are aparently in the ether an entirely new unsuspected family of electrical waves similar to electro magnetic radio waves. Electro-gravitic waves have been created and transmitted through concentric layers of electro-magnetic and electro-static shielding without apparent loss of power in any way. There is evidence that these waves are not limited by the speed of light. The new science seems to strike at the very foundations of the Relativity Theory, however, rather than invalidating current basic concepts, the new knowledge of gravity will probably expand their scope, ramifications and usefulness. It is this expansion of knowledge into the unknown that emphasizes just how little we know and how vast is the area still awaiting research and discovery.

The most successful line of the electro gravitics research so far reported is that carried on by Townsend Brown, an American who began researching gravity in the 1920s. He conducted research projects in the U.S. and Europe, postulating that there is between electricity and gravity a relationship parallel and/or similar to that which exists between electricity and magnetism. And as the coil is the usable link in the case of electro-magnetics, so is the condenser that link in the case of electro-gravitics. Years of successful research lend great credence to this hypothesis.

Other than the obvious military significance of electro-gravitic engines, the development of the new science will most certainly alter the value of certain raw materials. Some are more prone to induced weightlessness than others. These are becoming known as gravitic isotopes. Some are difficult to find, but others are common and, for the moment, cheap. Since these ultimately may be the vital lofting materials required in the creation of anti-gravitational fields, their value might become extremely high with equivalent rearrangement of the wealth of national natural resources, balance of economic power and global strategies.

How soon all this happens is directly proportional to the amount of effort expended. Surprisingly, those countries normally expected to lead the field wasted years before showing real interest. Before 1956, Great Britain, with her Ministry of Supply and the National Physical Laboratory, apparently never seriously considered that the attempt to overcome and control gravity was worth practical effort and had to work overtime to catch up.

The U.S. Department of Defense had consistently considered gravity as the realm of science fiction and, until the mid 1960s, only put token amounts of money into research. The French, apparently a little more open-minded about such things, initiated a number of projects, but even those were not properly funded. The same was true throughout most of the western world and, until less than five years ago, we could only guess what was going on behind the Iron Curtain.

Government and private interest is growing with each passing day and we should not be surprised to learn that space vehicles with anti-gravity engines and anti-mass fields from America, Great Britain and Russia have been zipping back and forth between Earth and the moon, or Earth and Mars for a number of years, perhaps since as early as 1960.

If so, the military has clamped a lid of secrecy on the projects that is impossible to penetrate and, now that the cold war is over, it leaves us to wonder why.
