The surprising discovery of "square ice" which forms at room temperature was made by an international team of researchers last week.

The study was published in Nature by a team of scientists from UK and Germany led by Andre Geim of University of Manchester and G. Algara-Siller of University of Ulm. The accompanying review article was done by Alan Soper of Rutherford Appleton Laboratory in UK.

"We didn't expect to find square ice ... We found there is something strange in terms of water going through [nanochannels]. It's going too fast. And you can't explain that by just imagining a very thin...

Forskere har kontrolleret luften bevægelser af frit-flyvende insekter ved hjælp af en radiosender og en miniature rygsæk af elektronik båret af "link".

Biller blev gjort at tage ud og lander, flyver til højre eller venstre, og endda at hover i midten flyvning afhængigt af radio kommandoer, link.

Hvis teknologien kan være yderligere raffineret, det ville være muligt i fremtiden at bruge flyvende insekter som miniature drones fyldt med bittesmå elektroniske sensorer for flyver over og søge vanskeligt terræn, de sagde.

Selv om elektronik tidligere har været anvendt til at kontrollere...
