What is Nano Medicine ?

The existing situation in the sphere of medicine, therapeutic methods of treatment and clinical psychology is determined to a considerable degree by discontent by practical means they have at their disposal. This actively prompts researches to search of new approaches to development of higher mental performance models and technologies of medical practice in the field of general therapy, contributing to creation of new effective methods of prevention and treatment of human diseases.  Modern medicine begins active use of nano-technologies gains and thus develops its new direction i.e. so called nano-medicine .  This article is a short analytic survey of nano-technologies that underwent clinic tests and have prospects of practical use in medical practice and pharmacy. In this article I will try to systemize and generalize problems and achievements of nano-medicine, a science that is not really wide existing, but only an incipient one. Leading scientists predict, it is this branc

Islam Contribution to Science World

Astronomy The most precise solar calendar, superior to the Julian, is the Jilali, devised under the supervision of Umar Khayyam. The Quran contains many references to astronomy: "And it is He who created the night and the day and the sun and the moon; all [heavenly bodies] in an orbit are swimming." [Noble Quran 21:33] These references, and the injunctions to learn, inspired the early Muslim scholars to study the heavens. They integrated the earlier works of the Indians, Persians and Greeks into a new synthesis. Ptolemy's Almagest (the title as we know it today is actually Arabic) was translated, studied and criticized. Many new stars were discovered, as we see in their Arabic names - Algol, Deneb, Betelgeuse, Rigel, Aldebaran. Astronomical tables were compiled, among them the Toledan tables, which were used by Copernicus, Tycho Brahe and Kepler

Penelitian : Ternyata Tumbuhan Juga Saling Berkomunikasi

Penelitian menyimpulkan bahwa tumbuhan ternyata saling berkomunikasi. Para peneliti memodifikasi gen kubis yang memicu keluarnya gas saat permukaan tanaman dipotong atau dilubangi. Modifikasi gen itu demi membuktikan bahwa tanaman "saling berbicara". Peneliti menambahkan luciferase protein ke DNA sehingga emisi tanaman 'dapat dipantau di depan kamera. Luciferase protein menimbulkan cahaya kunang-kunang dalam gelap. Tanaman kubis yang daunnya dipotong dengan gunting mulai memancarkan gas - jasmonat metil - yang 'memberitahu' tumbuhan di lain bahwa ada bahaya di sekitar mereka. Dua tanaman kubis di dekat tanaman yang dipotong itu menerima pesan untuk melindungi diri. Mereka melindungi diri dengan memproduksi bahan kimia beracun pada daun untuk menangkis predator seperti ulat. Ini adalah untuk pertama kalinya proses tersebut tertangkap kamera. Para ilmuwan mengatakan penelitian itu makin memperbesar dugaan bahwa semua tanaman berkomunikasi satu
