Há exatos 70 anos, o químico suíço Albert Hofmann experimentou a primeira viagem de LSD da história. Ele já havia sintetizado a droga em 1938 e testado a substância em animais, como parte de uma investigação de anos com derivados de ácidos lisérgicos. Mas em 16 de abril de 1943 ele decidiu cozinhar mais uma dose daquele que ele chamava de LSD-25 – e acidentalmente acabou provando a substância. Não demorou para que ele começasse a sentir algumas coisas estranhas, antes de pegar sua bicicleta de volta para casa. Pouca gente sabe, mas é por causa dessa pedalada de Hofmann que um dos  dos apelidos do LSD é “bike”. Conheça a história da invenção dessa droga e entenda como ela ajudou a escrever a história do século 20 nessas 5 páginas do Almanaque das Drogas publicadas como cortesia aqui embaixo.

Desert rose is the name given to rosette formations of crystal clusters of gypsum or baryte which contain an abundance of included sand grains. The rosette crystal habit tends to occur when the crystals form in arid sandy conditions. Gypsum roses usually have better defined, sharper edges than baryte roses. Celestine and other bladed evaporite minerals may also form rosette clusters.

Nature: Iron-60 is produced in tiny amounts by cosmic rays and in large amounts by supernovae. Given that ⁶⁰Fe does not form naturally on Earth, any significant concentration of the isotope is most likely have come from a past supernova. In 2004 researchers found ⁶⁰Fe in a sample of deep-ocean crust 2.2 million years old and attributed it to a nearby supernova. Now, Shawn Bishop of the Technical University of Munich and his colleagues believe they have found further evidence of the supernova in fossilized bacteria. From core samples dating to between 1.7 million and 3.3 million years ago, they took samples from strata formed roughly 100 000 years apart. They washed the slices with a chemical that would remove ⁶⁰Fe that was present in any nonbiological sources. Then they examined the slices in a mass spectrometer and found what appeared to be ⁶⁰Fe, but only in the layer corresponding to 2.2 million years ago. Bishop says that the isotope was likely incorporated into magnetite (Fe₃O₄) chains by bacteria on the sea floor.

(Phys.org) —In most demonstrations of quantum teleportation between remote atomic qubits, the atoms exist in free space. In a new study, scientists have discovered that trapping the atoms in optical cavities can overcome some of the previous obstacles facing matter teleportation, which enables an improvement in efficiency of almost 5 orders of magnitude and teleportation across a record-breaking distance of 21 m. These improvements in quantum teleportation could open the doors to realizing quantum networks with many nodes for teleporting qubits to various destinations.

Engineers have developed a method of creating and controlling plasma that could revolutionize American energy generation and storage.

Leap Motion announced today that it's partnering with Hewlett Packard to release the first line of built-in gesture controlled computers. The companies declined to say whether the models would be laptops or desktops, or pin down an exact release date, except to say the computers would be the first models hitting the market with gesture devices embedded directly in the computer shell. It's a good sign, as Leap Motion rushes towards its official release date on May 13th and tries to build enough interest in its app store to keep both developers and users happy.

Nearly ten years ago, well before Android became the dominant smartphone operating system it is today, Andy Rubin and his colleagues were designing it as a software platform for cameras. That revelation came from Rubin himself during a presentation at Japan's New Economy Summit. According to PCWorld, Android in its earliest days was intended to improve the connection between digital cameras and PCs. Bringing new app experiences to cameras — a relatively stubborn market at the time — also seemed to be on the radar.

"We thought it would be good if we could build a camera platform with third-party apps," Rubin said. Ultimately though, even before Apple's iPhone had launched to consumers, the mobile trend became clear. "We decided...

Spanish industry is leading the Proba-3 mission, a world first in precise formation flying. This European Space Agency (ESA) project aims to demonstrate that two satellites can move as one single object with sub-millimetre precision. This configuration will enable the creation of enormous space telescopes with the lens and detector hundreds of metres apart.
