PRIMER CELULAR CHARGABLE CON SOLAR

El segundo fabricante mundial de teléfonoscelulares, el surcoreano Samsung Electronics, ha producido el primer móvil del mundo equipado con un panel solar para recargar su batería, informó hoy la agencia local Yonhap.El móvil, denominado “Blue Earth” (Tierra Azul), será presentado durante el Congreso Mundial de Celulares, que se celebrará en Barcelona entre los días 16 y 19 de este mes, reseñó Efe.Se trata del primer celular del mundo equipado con una batería que se carga mediante un panel solar incorporado en la parte trasera del propio aparato, que genera energía suficiente para realizar llamadas.El teléfono está fabricado además con materiales ecológicos, según la compañía, que afirma que una carga de 10 minutos en el panel solar es suficiente para realizar una llamada de tres minutos.La parte exterior del teléfono está compuesta de material reciclado a partir de botellas de agua de plástico lo cual, según la compañía, ayuda a reutilizar los recursos.

WHO INVENTED THE TEA BAG?

The first tea bags were made from hand-sewn silk muslin bags and there are tea bag patents of this sort dating as early as 1903. First appearing commercially around 1904, tea bags were successfully marketed by tea and coffee shop merchant Thomas Sullivan of New York, who shipped his tea bags around the world. A machine was soon invented to replace the hand sewing of tea bags.

WHO DISCOVERED DNA?

It was Crick and Watson who worked out the structure of DNA in the 1950's, but its discovery was made nearly 100 years previously by a Swiss physician called Frederick Miescher.

The man who discovered DNA, Frederick Miescher, was a young physician who worked in the laboratory of physiological chemistry of eminent scientist Felix Hoppe-Seyler. At the time of the discovery he was in his 25th year and had not long graduated from his studies.
His research interest was focused on understanding the chemistry of the cell, because of his belief that it would help to solve the problems of tissue development.

The Discovery of DNA
Miescher discovered DNA in 1869 whilst studying pus-ridden bandages that were being sent to the laboratory by the local clinic. At this time the lab was working on the chemistry of body fluids, particularly blood. To that end the young physician was studying lymphocytes, though these were hard to obtain. So he was isolating leukocytes (which were thought to be derived from lymphocytes) from pus. Once these cells were prepared he managed to isolate pure nuclei, and from there he extracted a high-phosphorus containing substance, and described it.

The man who discovered DNA did not know that it was the hereditary material and he also did not call it DNA. He referred to it as 'nuclein' because it had come from the nucleus. He expected it to be present in organs such as the liver and kidney, and he also believed it to be an acid. He wrote to his uncle, "With experiments using other tissues, it seems probable to me that a whole family of such slightly varying phosphourous-containing substances will appear, as a group of nucleins, equivalent to the proteins." Thus he had discovered nucleic acid, but it was two years before his work was published because his laboratory head wanted to replicate the results.

Nuclein
So Miescher had shown that the material inside the nucleus was different from the material inside the cell cytoplasm, and indeed was not present there. This was an unconventional view at the time because scientists would have expected the same material i.e. protein to be present throughout the cell.

Miescher also managed to chracterise the chemical components of this 'nuclein' acid - although not with the familiar names of bases that we're used to. He identified the components as N, C, H, O and P.
The man who discovered DNA also worked with salmon cells and managed to isolate nuclein from salmon spermatozoa. Again he did not really know what this material was for. The discovery of its true nature came many years later and by other scientists.

WHO INVENTED THE BANANA SPLIT

A banana split is an ice cream-based dessert. In its classic form it is served in a long dish called a "boat". It was reportedly invented in 1904 by David E. Strickler a 1906 graduate of the University of Pittsburgh. A banana is cut in two lengthwise (hence the split) and laid in the dish. Variations abound, but the classic banana split is made with scoops of vanilla, chocolate and strawberry ice cream served in a row on the split banana. Pineapple topping is spooned over the vanilla ice cream, chocolate syrup over the chocolate ice cream and strawberries over the strawberry ice cream.

THE USB HAMSTER WHEEL

The more you work, the more the hamster sweats! No one should do without this new invention. You can spend all day watch an artificial hamster run as the wheelk goes roung and round. There is only one small trick to all this. the wheel only spins IF you are typing and the faster you type, the faster it spins. as we haven´t tried it , we can´t tell if the hamster goes flying from the wheel if the speed increases but that could be a great final some people think. I for one think that would be very sad.

Mientras más trabajes más sudará el hámster.¡Por supuesto que sí! A nada le puede faltar este último resultado de la tecnología actual. Con esta rueda de hámster puedes pasarte todo el día mirando como un animalejo artificial corre sobre una rueda. Pero tiene un truco. La rueda no gira por sí sola, sino que gira dependiendo de qué tan rápido escribas en el teclado. Eso quiere decir que mientras más rápido escribas, más rápido correrá el animalito. Como no lo hemos probado no sabemos si al final el hámster sale volando, pero sería un gran final creen unas personas. Pero no estoy de acuerdo con eso.

WHO INVENTED THE VENTILATING KEYBOARD ( WRITTEN IN ENGLISH AND SPANISH)

THANKO Co. seem to have no end for their creativity. In this case, they have thought up how to deal with sweaty hands working on a computer. The Cooler Keyboard has three tiny ventilators which given air to the hands causing them to remain dry from perspiration.The ventilators work with the help of an additional USB Cable and it can be yours for 62 dollars or 39.51 Euros.


La gente de Thanko no para y su creatividad parece no conocer límites. En este caso aportan una solución a las sudorosas manos consecuencia de las temperaturas estivales. El teclado Cooler Keyboard incorpora tres pequeños ventiladores que airen la base de nuestras manos de forma que secan convenientemente el sudor de nuestras manos. Los ventiladores son alimentados vía un cable adicional USB. Puede ser tuyo por 62 dólares (39,51 euros).

WHO INVENTED THE MOUSE

The History of the Computer Mouse and the Prototype for Windows - Douglas Engelbart
By Mary Bellis
"It would be wonderful if I can inspire others, who are struggling to realize their dreams, to say 'if this country kid could do it, let me keep slogging away'." - Douglas Engelbart
Douglas Engelbart changed the way computers worked, from specialized machinery that only a trained scientist could use, to a user-friendly tool that almost anyone can use. He invented or contributed to several interactive, user-friendly devices: the computer mouse, windows, computer video teleconferencing, hypermedia, groupware, email, the Internet and more.
In 1964, the first prototype computer mouse was made to use with a graphical user interface (GUI), 'windows'. Engelbart received a patent for the wooden shell with two metal wheels (computer mouse U.S. Patent # 3,541,541) in 1970, describing it in the patent application as an "X-Y position indicator for a display system." "It was nicknamed the mouse because the tail came out the end," Engelbart revealed about his invention. His version of windows was not considered patentable (no software patents were issued at that time), but Douglas Engelbart has over 45 other patents to his name.
Throughout the '60s and '70s, while working at his own lab (Augmentation Research Center, Stanford Research Institute), Engelbart dedicated himself to creating a hypermedia groupware system called NLS (for oNLine System). Most of his accomplishments, including the computer mouse and windows, were part of NLS.
In 1968, a 90-minute, staged public demonstration of a networked computer system was held at the Augmentation Research Center -- the first public appearance of the mouse, windows, hypermedia with object linking and addressing, and video teleconferencing.
Douglas Engelbart was awarded the 1997 Lemelson-MIT Prize of $500,000, the world's largest single prize for invention and innovation. In 1998, he was inducted into the National Inventors Hall of Fame.
Currently, Douglas Engelbart is the director of his company, Bootstrap Institute in Fremont, California, which promotes the concept of Collective IQ. Ironically, Bootstrap is housed rent free courtesy of the Logitech Corp., a famous manufacturer of computer mice.
