يقوم باحثون حاليا بتطوير أطراف صناعية ذكية مغطاة بجلد صناعي لنقل أحاسيس كالبرودة والسخونة وغيرها تحاكي الأعضاء الطبيعية وذلك لتعويض مستخدمي الأطراف الصناعية عن فقدانهم لأعضائهم، وذلك وفق صحيفة فرانكفورت الغماينة

يعكف الباحثون، حسب جريدة فرانكفورت الغماينة الألمانية، على تطوير آليات الأطراف الصناعية وبالتحديد الأيدي، وذلك ليتمكن مستخدموها من الشعور بالألم والبرد والأحاسيس التي تنقل عبر اللمس. ويعمل الباحثون في جامعة سيول الكورية حاليا على تطوير جلد صناعي لنقل هذه الأحاسيس عبر اللمس في الأيادي الصناعية.

فإذا ما ركبت قطع من الجلد الصناعي على الأطراف الصناعية تتمكن ناقلاتها من إدراك البرودة والسخونة والرطوبة والجفاف. كما أن طبقة الجلد الصناعية تسجل إذا ما كانت اليد مضمومة القبضة أم منفرجة.

الأطراف الصناعية بشكل عام تساعد في تعويض الأفراد عن الأعضاء المفقودة، لكنها حتى الآن لا يمكنها أن تعوضهم الإدراك والمشاعر التي كانوا يشعرون بها حين كانوا يستخدمون أطرافهم الطبيعية، وهو ما يعكف الباحثون على تغييره، بحسب جريدة فرانكفورت الغماينة .

Plant represents "tubal" prankster who eats ants and grows in Indonesia living proof that savvy alone is not enough to trump the prey, but there are natural factors help to capture the prey and feeding them.



Scientists said that a plant to grow in Ahma lane on the island of Borneo Indonesian areas usually take advantage of the natural fluctuations in the weather for the monument to Fajakhh slippery snatch and feeds on swarms of ants once, instead of that feeds them individually. And ensures Find Asian types of tubal plant, which took its name from the trumpet-like shape of the leaves, which represents a trap in which slip insects. And when they are wet edge trumpet plant they become slippery dramatically, falling to the ants, which runs on the surface and it becomes an easy prey to this predator plant.

However, in the sunny weather warm, dry surface trumpet and is safe for the conduct of ants. Therefore, the teams of ants exploratory trips take the survey and collect nectar fresh from the plant "tubal" before it closed due to their nests to tell her peers whereabouts of this delicacy. Then going swarms of ants, which told the importance of nectar, then towards the plant "tubal" (trap) and is oblivious, in search of food, to be out of rhythm, because the plant would then deliberately to make the slippery trap can not escape from it. Therefore, the plant may be left members of the Boy Scouts of ants in the event of the process, but he cheated swarms over a number of Ilthmha in the end.
Exploitation of natural factors to catch prey
The plant produces "tubal" sugary sap to make a trap slippery and wet, through the intensification of water vapor at low levels of moisture compared to the surfaces of other plants. This contributes to the revitalization of the trap during the afternoon when the insects are most active during the day are still roaming the place.
He said Ulrike Bauer, a biologist at the University of Bristol, UK, who led the study, which was published in the journal (Proceedings Of The Royal Society B) competent to publish scientific reports of the Royal Society, that the plant is not intelligent human sense of the word, he is not able to draw up a plan, for example, , but naturally not take mercy and turn to one of the successful strategies to provide nourishment.


It is noteworthy that there are about 600 species of this broiler plant in the world, and usually grows tubal plant in the living places of scarce food, making it tends to grab a prey animal to feed them. Most of these species and catch insects, but few of them hunt small mammals and collect droppings to feed on them.

In a new innovation in the world of smart phone industry company wishing to launch Google phone component units demountable and installation, allowing the user to update the phone and use it for a longer period. The phone will be put on the market later this year.
Allows the project "Ara", launched by giant Google Inc., for each user installation to suit his requirements, and through the development of digital units demountable and installation allowing users to provide smart phones with the latest innovations and jobs.
Google and manufactures internal structure of the phone, while the rest of the removable installation such as batteries and screen and other components, will be developed and manufactured by another product.
Google began developing the project "Ara" in 2013, according to the company, the new Google phone will start marketing a pilot in the "Puerto Rico" at the end of the year 2015.
The internal structure of the device will be available in three sizes, and this structure can be installed in different units using a magnetic holder. Google will add a so-called unit development "Kate" digital tool which is necessary to add the appropriate units of information storage. Google intends to subsequently sell some units across the Internet, such as digital unit for measuring the level of sugar in the blood.
Referred to as the "Ara" project does not aim to develop smart phones with more features, but smart phones allow the user to replace the old parts and updated, allowing to use the phone for a longer period.

Most of the gold that has been discovered since the year 6000 is still Possession rights. Had this been assembled gold was melted Is a rib 59 cubic feet and weighs 103,000 metric tons
Oktralamaadn gold is softer and can voluntarily withdraw Per ounce in the form of wire length of 5 miles or roads In the form of a thin plate so highly covers an area
Of 100 square feet.

Sometimes golden chips are used for the work of decorative cake and often this is happening in Japan.
The first production of gold in the United States was in the north Karawlinaa and not in California, in 1799 and then followed by other yields in Georgia in 1828.

American and German scientists announced that a new dynamic is able to detect anti killed a large number of bacteria effectively, and said that these bacteria could mutate in the face of antibiotic new little, and called the name of the new article Taiksubaktin.


Scientists from the United States and Germany said they have discovered a new anti vital able to kill a large number of bacteria effectively. The researchers explained that these bacteria could mutate in the face of new antibiotic little. Experts called the new article name Taiksubaktin.
The researchers explained under the supervision of Kim Lewis of Boston University in their study - which published its findings Wednesday (the seventh of January 2015) in the journal "Nature," the British - that nature has a large stockpile of antibiotics.
And remained antibiotics discovered in the twentieth century of the most important scientific achievements in the field of medicine, despite the fact that most of these antibiotics discovered early in the period between 1940 and 1960. However, the germs that targeted antibiotics soon be a reluctance to antibiotics, which made medical scientists complain years ago from lack of discovery of new antibiotics defies germs.
Most of the antibiotics in the development of scientific laboratories using fungi and bacteria, but it's hard a lot of these antibiotics in agriculture laboratory conditions. Sometimes antibiotics are being developed in laboratory conditions only a small fraction of their capacity to kill germs do not appear.
The researchers under the direction of Lewis analyzed 10 thousand trunk from soil bacteria in the center looks like a natural environment in which they live, and analyzed the effectiveness of the materials produced by these bacteria to kill harmful to humans germs, and found during that a substance produced by bacteria Eleftheria Terry called it Taiksubaktin name, and show them that this active substance prevents the bacteria that infect the cell wall and through association with sugar molecules that contain fat. It is the same mechanism by which they operate vancomycin active substance that was discovered in 1953, while the material Taiksubaktin also effective against germs that have the ability of immune substance against vancomycin.
