Asterisk robot

Asterisk robot

It was revealed Asterisk robot inspired by a spider
Asterisk is a robot developed by Osaka University, Japan, and inspired by the body of a spider. Certainly not the only creation inspired by the animal world, but is one of the best projects ever seen.
Robot-spider (which is only 6 feet but unlike true spiders, which have eight) has four degrees of freedom for each member and can move either with small metal plates attached to the ends of the legs, either by means of wheels, depending on the environment in which it is located. By means of video cameras and infrared sensors embedded in the “knee”, the robot can avoid obstacles can be high or stoop to pass under low lift objects.
Like an ant, the robot can stand on four legs, and the other two uses to perform certain tasks. The most impressive thing that Asterisk can do is climb on walls and nets arranged vertically. Because it does not distinguish between up and down, the robot spider legs can easily twist 180 degrees, landing on the 6 States safely.

Japanese laboratories Asterisk stood for six years, and its creators hope that one day the spider robot can be used in disaster situations, such as those that have befallen Japan this year.
It was invented microrobot walking on water!
Scientists have developed a new aquatic microrobot that mimics the amazing capabilities of a water strider – the long-legged insect moving on the surface of ponds or lakes.
Bionic microrobot has undergone improvements over previous models, and is now targeted as the first option in military intelligence missions, water pollution monitoring, and other operations. The study was recently published in ACS Applied Materials & Interfaces.
“For humans, walking on water is just a dream, but for some insects this is a way of life,” the researchers wrote in their paper. This ability is due, in large part, their feet waterproof (superhydrophobic).

So far, countless researchers have tried to develop such robots to be used in monitoring water supply or to conduct military spy missions. However, until now, no one has managed to find a way to create such robots that prove practices and agile.
The new prototype is the size of a US 25-cent coin (25 mm) and has thin legs propelled by two miniature motors. Despite the weight of the robot is equal to 390 water spiders, insects that a copying machine, it moves very easily with water.

Philae robot continues

Philae robot continues

Philae, launched Wednesday aboard the Rosetta space probe to the comet’s surface, came in a shaded area of it. A video camera on board the spacecraft, orbiting at less than 16 km altitude of comet captured in pictures last minutes of descent Philae on its surface, which lasted a total of seven hours. The footage is observed ESA months where Philae comet reached and reached the region where, finally, after jumping like a ball on the body surface space.
Jump the robot, which was not foreseen was the consequence of the failure of the fastening system of Philae, which did not go off properly and not anchored. Philae thus reached a shaded area where you can not recharge its batteries using solar light energy as needed for expanded mission.0

ESA scientists waited anxiously information as Philae started a series of automated experiments, including drilling, and, fortunately, had enough energy to transmit information by radio waves to probe Rosetta, who then forwarded them to the Terra.
Before their stop systems and to enter into a state of hibernation, Philae has changed little position to try to gain access to more sunlight for photovoltaic panels covering one of the robot body, but immediately after rotation remained without power, and its systems were closed.
Comet 67P / Ciuriumov – Gherasimenko are turning to the sun, accompanied by the Rosetta probe.
Increasing the amount of light could be useful for charging batteries Philae. As the comet is heated jets of gas are released from its depths, which could result in moving the robot and moving it where the shaded region.
The first results of Rosetta mission are expected in December, when they will be presented at the American Geophysical Union conference in San Francisco.
Launched in 2004, the ESA Rosetta mission is dedicated to staying more data on the origins of the solar system, and the robot’s mission Philae collection of organic molecules that could play a role in the emergence of life on Earth.

Comets are the most primitive bodies in the Solar System. Rosetta probe has already sent the first images ever made of the surface of a comet.
Little robot could radiography inside comet to study magnetism to achieve images with the ground, to analyze complex molecules from the surface.
According to experts from the Centre National d’Etudes Spatiales (CNES), French space agency, its mission is achieved in 80%. After three days of work, “the results are extraordinary Philae”, says Marc Pircher, Director of CNES.
If restoring contact, if everything works as planned, Philae should “hot mill” in March 2015, when the comet will approach the sun.
But Rosetta will continue its mission of “accompanying” comet-Gherasimenko Ciuriumov at least until August 13, 2015, when the comet will pass to the shortest distance from the sun. Its mission is scheduled to last until the end of December 2015.
Placing a robot on a comet at a distance of 500 million kilometers from Earth is a first in the history of space exploration and a highlight of a mission that began 20 years ago.
With a total cost of 1.3 billion euros, the equivalent of three Airbus 380, Rosetta mission has deployed approximately 2,000 researchers over 20 years. Over 50 companies from 14 European countries and the United States participated in making this space probes.

Enjoying The PlayStation Network

These are some of the basics that are going to culminate in beginning your experience with the PlayStation Network.


PlayStation video game console, the first of its kind made by Sony Computer Entertainment, was released on 3 December 1994 in Japan. It is the first console distributed more than 100 million units, nine and a half years after launch.

Its successor was the PlayStation 2, put up for sale in 2000. The PS2 had to beat every sales record in the field, with over 155 million units sold by 28 December 2012. Since December 2012, the PS2 is no longer delivered to Japan and according to the Guardian, the console has been removed from production in January 2013. All of these consoles until now there have been very popular because a single program, it is called PSN code generator. It can create codes for purchasing original games.

Inventor of dynamite

Inventor of dynamite

   On the other hand, neither Alfred was simply overwhelmed by the first failures of his career, which seems to be an exception. After the Swedish authorities have forbidden to do experiments across the capital Stockholm, Alfred arranged his laboratory near Lake Malaren, an isolated area without human settlements. Profoundly affected not only his brother but also the thousands of deaths of miners from all over Europe, who used mainly as dangerous explosive nitroglycerin, Alfred Nobel devotes an explosive discovery efforts safely and effectively.



Start with all nitroglycerin as a starting material, which adds ameliorating various types of substances. Version proved lucky diatomaceous site, called diatomite (a siliceous sedimentary rock), which he mixed with nitroglycerin, thereby converting dangerous explosive liquid into a paste which later solidified.

Nobel chuckle. New substances have the same devastating explosive power of nitroglycerin, just that it was much more stable and resistant to mechanical shocks.

Alfred Nobel christened it the first time, dynamite and patented it in 1867.

To be successfully detonated safely, the brilliant scientist invented and classic detonation system – blasting caps are attached to the end of sticks of dynamite and was activated by the wick lit.

In the same historical period, were invented and pneumatic hammer drill, drill the head with artficial Diament. The mining industry has taken on new proportions. With the pneumatic hammer and drill special holes could be made in most hard rock, and the holes created were placed explosive dynamite sticks created by Swedish inventor.

The first demonstrations took place in mine Redhill in Surrey, England.

In order to separate the company names above in connection with explosives dangerous Nobel insists containers with new explosives to be engraved original logo “Nobel’s Safety Powder” was later changed to dynamite, a term that originates in a word from the ancient Greek that means power, force (also here we have the term dynamism or, if you will, Dinamo …)

Nobel previously combined nitroglycerin with various nitrocellulose compounds but, dissatisfied with the results, then added to the mixture nitrates, finally obtaining an explosive substance stronger than the dynamite. It’s gelignite, an explosive gelatin patented in 1877 Very stable and easily molded into various shapes, gelignite was one that enriched the Nobel.

However, searches and his research in the field has not been curbed by financial success, Alfred Nobel discovered and ballistics, a chemical precursor of today’s explosive powders, still used to launch missiles.

Scientist and florist

Its success exceeded all estimates and expectations. Nobel traveling the world, founding over 90 labs and production centers in 20 countries. Although chose Paris as the official residence was on the road all the time. Victor Hugo, one of his close friends, he used to tease him calling it “Europe’s richest vagabond”.

Spirit Seeker, Nobel arficial contributed to the invention of rubber, artificial skin and artificial silk. Until his death in 1896, Nobel patented 355 inventions.

Although he remained married until his death, according to data collected by his biographers, the brilliant scientist remained indifenent to charm the fair sex, having at least three memorable love. The first was held in Russia relationship with a young woman named Alexandra, who rejected the request for marriage.

Intensive work and research have not left much time for love life. At 43 years, as testified to close, already felt old and tired.

However, a notice posted by the illustrious scholar in a newspaper of the time tells us much about Alfred Nobel, the man behind the inventor:

“Gentleman rich and highly educated, looking for a middle aged lady, cunoscătoarea several languages​​, the role of secretary and maid …”

The only scholar who meet the criteria proved Bertha Kinsky, an Austrian countess, that Nobel was love. After a brief relationship, Countess left him to marry her former lover, Baron Arthur von Suttner Gundaccar.

Despite the separation, the Countess gave a continuous correspondence with Nobel scientist until death. In the letters, it is believed that Bertha Kinsky had a major influence on the peace prize idea.

The last and longest Nobel’s emotional relationship was with a simple florist in Vienna named Sofie Hess. The relationship lasted 18 years, and Alfred often called “Lady Sophie Nobel”.

Alfred Nobel – Man. Dynamite. Awards

Alfred Nobel – Man. Dynamite. Awards

It was one of the most famous personalities of the nineteenth century. Inventions, vision and generosity would mark the profound and development of human civilization. He was a visionary but also – perhaps a greater extent – a full-fledged patron. He remained a reference point, a living symbol and an inspiration to many. Today, his name remained attached to the most coveted and prestigious award in the world, whose award continues to be the most important event of its kind in the political, cultural and international science.

Alfred Nobel

A inventors family

Fate decided that the great inventor and visionary later to see the light of day on October 21, 1833, in a family where science and knowledge were at a premium. He was the third son of Immanuel Nobel and the Nobel Ahlsell Andriettei. His father, a renowned scientist and inventor of the time, was a descendant of the famous Swedish scientist Olof Rudbeckia.

Born in Stockholm, Alfred breakfast with all the family moved to St. Petersburg, where his father (who, among other things, invented plywood wood), have several contracts honored.

Alfred inherited the family’s appetite for science and research.

He was attracted, during adolescence, the mysteries of chemistry, which he studied with one of the most prestigious teachers of the time, Nikolai Nikolaevich Zinin. Young was already a versatile man, being endowed with a great capacity to learn all sorts of things (at the age of only 17 years was fluent in Swedish, Russian, French, English and German), but his great love remained chemistry. After the age of 18 years, Alfred traveled to the United States for a period of four years, has depth study of chemistry under the guidance of Professor John Ericsson, who, among others, conceived and designed armored ship USS Ironclad, became famous during the American Civil War.

At home, on the Old Continent, the family business is down, factory run by his older brother, Ludvig, finally entering bankruptcy. Back in his native Sweden, with his father, Alfred decides to pursue research in France.

Fire very smart and pragmatic, the young Swedish predicts the value and importance of explosives in various fields of fresh plant industrial age.

It grabs so research on explosives, while nitroglycerin marketing, the most powerful explosive at the time, discovered in 1847 by Ascanio Sobrero.

Experience and new formula combines the powerful liquid explosive, trying to create a type of nitroglycerin as stable as possible, not explode at the smallest movement. The terrible explosion in 1864 at its plant explosives Heleneborg in Stockholm, leading to the tragic death of five people, among them the youngest Nobel and his brother Alfred, Emil.

Deeply shocked and considering moral culprit behind the tragedy, Alfred Nobel receives a blow from the Swedish authorities, who take the decision to close the plant, considering the explosive activities as too dangerous to still be allowed.

However, his father and brother continue their business in Russia, delivering explosives for military Tsarist Empire and venturing success filled with oil exploitation in the North Caucasus. At least financially, fortune began to smile again, tried Nobel families, tsarist army contracts and oil wells in Azerbaijan and Chechnya turning them into some of the richest people of that periode.

Drones affect privacy?

Drones affect privacy?

Some activists fear that the spread of drones will lead to violations of privacy.

Raoul Felder, a New York attorney specializing in divorces, says that “if the Israelis can use drones to track down terrorists, then surely a husband may use a drone to pursue his wife when she leaves the house at times the later “..


Moreover, the design professionals working for the military drones are already thinking about how they can be used by the population.



Missy Cummings, a former Navy pilot USA, currently a professor at MIT (Massachusetts Institute of Technology), works with his students to design a personal drone, the size of a pizza box. Boeing ordered drone role is to accompany the soldiers on the battlefield and warn when identifying a potential danger. Cummings says that the same drone could have many civilian applications. “A parent could use it to track children on their way to school, to ensure that they get there safely, and schools could use drones to monitor the perimeter.”

If drones could affect privacy by their ubiquity, the same could have positive consequences. Andrew Stobo Sniderman and Mark Hanis, Genocide Intervention Network co-founders, argued in a recent article in the New York Times that the drones could be used to prevent genocide in that it can shoot air incidents where human rights are violated, making it impossible to hidden massacres such as occurred in Srebrenica in 1995.

Future drones – autonomous robots?

The next step that the American military has in mind is equipping drones with the ability to identify one enemy targets without human assistance.

Currently, weapons are equipped drones patrolling the battlefields are released only after orders pilots, but American researchers working on the design of systems able to take autonomous decisions.

At the border between South Korea and North Korea are already “robotic guards” capable autonomous decisions. Turetele “Super Aegis 2” can detect a human from 2.2 miles away, whatever the weather, attacking enemies with a machine gun 12.7 mm caliber.

Specialists consider that not long before, and the drones will become autonomous and will identify enemies with sophisticated algorithms and then to attack with their weapons.

Ronald C. Arkin, author of the study “Governing Lethal Behavior in Autonomous Robots” funded by the research wing of the American army, states that “Lethal autonomy is inevitable”. USA is the only country that carries out research in this area, China is also investing significant sums.

Estimated that in 2030 the United States Army drones the size of insects, equipped with cameras and sensors will be used for espionage. This prediction may come true even sooner than 2030, a team of researchers at the Harvard lab microrobot created using a 3D printer, a mini-drone the size of a coin, called Mobe. All these efforts seem to outline a future where the sky is studded by thousands of drones, which will be integrated into everyday life in what promises to be “era drones”.

Also, the new drone could prove paparazzi dream tools, whose name comes from the idea of ​​”insects buzzing” during which this metaphor will come alive. Several personal drones are already scheduled to be built next year. In the UK, authorities are already using this type of drone to track the villains. Air robots measuring about half a meter between each two opposing propellers of four rotors that have and employ unmanned flying vehicle technology, originally designed for military reconnaissance missions. Battery-powered device is equipped with CCTV surveillance cameras and thermal lens detector. Drones are designed so as to fly over airspace quiet and transmit real-time images of police on the ground. Of course, machines can be stationed on different surfaces suspended prestandu their tasks with the same efficiency. Price drones used by the British authorities is around 45,000 euros each.

Lazar Edeleanu

Lazar Edeleanu

Lazar Edeleanu chemist who founded the oil processing.
“A man and nature, an ornament of science novels” – so described on the chemist, geologist Louis Mrazec Edeleanu Roman Lazar, who found an innovative method of coke, used worldwide.

The scientist was extremely prolific, having already won 212 patents.
Future chemist was born in Bucharest on September 1, 1862, in a large family, his father being a turner. Later, during his childhood, moved in Focsani.
But at age 12, Lazar Edeleanu was sent back to the capital, his parents recognizing the affinity for sciences.
He studied at the “Sf. Sava” and earn it in meditation and living in poor conditions, living in a basement. He worked hard for a year after sustaining baccalaureate (1882) to raise the money needed to continue their studies.
He went to Berlin to teach chemistry under the guidance of teachers of the time in May, including the AW Hofmann, C.F. Rammelsberg and H.L. Helmholtz. In 1887, he obtained his Ph.D. in chemistry with the thesis “On some derivatives of fatty fenilmetacrilici and fenilizobutirici” in which a synthesized substance later became known as amphetamine.
War amphetamine: discovered a novel, “stolen” by the Americans and used massive Wehrmacht
But the novel has not exploited this discovery as another invention became known worldwide: petroleum refining liquid sulfur dioxide, which provides selective extraction of aromatic hydrocarbons (benzene, toluene, xylene, etc.).
The method was applied for the first experimental Vega refinery in Romania, where he was also director, then in France and later industrial world. Starting in 1910, settled in Germany, where he focused on the industrialization of the process, being the director of a major research institution, which, in honor of the inventor novel was named “Edeleanu Gesellschaft” and is also currently in Frankfurt.
This company has registered the brand in 1932 “Edeleanu” (renewed until today) for product groups: hydrocarbons, motor fuels, oils, transformer oils and turbine switches, white oil, machinery and equipment elements for improving oil .
Scientific heritage is a rich Roman chemist as renowned scholar and distinguished colleague, Costin D. Nenitescu “Edeleanu process became and still is today, in the form of its many variations, the basic process of manufacturing high quality oils” .
Edeleanu obtained 212 patents in Romania, but also in the USA, Germany, France, Austria, Sweden, the Netherlands, was ordered King Leopold of Belgium, with the rank of officer, was a member of the “Society of Natural Sciences” in Moscow
and honorary member of the “Institute of Petroleum Technologists” in London, among others.
Great chemist died on April 7, 1941, in Bucharest, but he left behind a huge work of During the National Socialist regime in Germany Edeleanu company was bought by Deutsche Erdöl-AG company and then passed from hand to hand until it was bought in 2002 by the company Uhde, ThyssenKrupp owned corporation.research that started a million dollar industries: oil processing.
He made many studies in organic chemistry related to: unsaturated acids aromatic series, the action of sulfur chloride on aniline derivatives and fenilizobuteric fenilmetacrilic acid or cloralului action on oxiacizilor. Fenilizopropilamina synthesized in 1887 (he established formula), and in 1907 managed to achieve separation of Berka topping of sour crude oils, Campeni and Campina (benzene, toluene, xylene and pseudocumen). He showed quantitative and qualitative benefits of obtaining aromatic hydrocarbons from the oil from coal. He is the author process (which bears his name) selective refining petroleum fractions based on solubility specific to different classes of hidrocarduri in liquid sulfur dioxide. The procedure was first used in World Vega refinery in Ploiesti, the process was subsequently adopted by other countries.

3D mammography saves lives

3D mammography saves lives

3D Mammography allows detection of more breast cancers and reduce the number of erroneous diagnoses compared with conventional radiography, according to results of a large clinical trial.

Compared to 2D mammography, digital mammography tomosynthesis 3D 41% detection rate of invasive breast tumors and 29% detection of all breast cancers.


This three-dimensional imaging technique approved by the American Agency for Drug Administration (FDA) in 2011 led to a 15% reduction in the number of incorrect diagnoses (positive and negative), says the authors of the study published in the Journal of the American Medical Association (JAMA ).


The study, the largest conducted to date on the effectiveness of this technique for screening was performed on nearly half a million women hospitalized in 13 medical centers in the United States.


“This study confirms what we already knew: 3D mammography detects more cancers invasive and women relieve their anxiety and costs of further analysis to confirm that it was a false alarm,” said Donna Plech physician at Case Medical Center of the American city of Cleveland.


The new method, which combines digital mammography and tomosynthesis imaging allows to obtain more detailed images and more focused on breast cells. They are used to produce a series of collages with thickness of 1 mm, which can be viewed in a 3D reconstruction of the breast.

The technique is not much different from conventional mammography, since it takes only a few seconds longer than this.


When it is discovered breast cancer determines patient’s chances of survival. It is therefore very important that women over 40 have a mammogram annually.

If a cancer is detected early enough and has not spread beyond the breast, the survival rate for the next five years is 97%, the study authors stressed.

One woman in eight will suffer from breast cancer at some point in her life in the United States.

According to the American Cancer Society, 235,000 American women will be found in 2014 with breast cancer, and the disease will be fatal for 40,430 of them.

Approximately 232,000 new cases of breast cancer are diagnosed each year in the United States, where record 39,000 deaths per year, according to the National Cancer Institute. American women 12.3% risk of developing the disease at some point in life, and has a five-year survival rate of 89%.


In 2009, the Preventive Services Task Force (USPSTF), an independent expert group that enjoys broad authority in the United States changed the previous rules, recommending a mammogram every 1-2 years from age 40 years and this procedure every year after the age of 50 years.


That decision was based on new data that the report benefits – risks associated with mammography is higher for women over 50 years.


But this new recommendation remains controversial among the general public, as in the medical community and a series of recent data seem to indicate that the frequency of use of mammography has not changed in the United States after the changes made by the USPSTF.
