To get the best care for her three autistic children, Mandi Larkin would drive three hours from her family’s home in Tifton, Ga., to Marcus Autism Center in Atlanta. The drive to and from Atlanta was exhausting. Missed work, missed school and the long drive were constant sources of stress. (more…)
Physicists have experimentally encoded one quantum bit (qubit) in entangled states distributed over several particles and for the first time carried out simple computations on it. The 7-qubit quantum register could be used as the main building block for a quantum computer that corrects any type of error. The researchers’ results have now been published in Science. (more…)
A track about one-third of a mile (500 meters) long on Mars shows where an irregularly shaped boulder careened downhill to its current upright position, seen in a July 3, 2014, image from the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter.

Verschränkte Photonen bilden ein Objekt ab, ohne in seine Nähe zu kommen
Normalerweise bildet man einen Gegenstand ab, indem man ihn mit Licht bestrahlt und anschließend die von ihm kommenden Lichtquanten oder Photonen mit einer Kamera auffängt. ForscherInnen um Gabriela Barreto Lemos und Anton Zeilinger von der Universität Wien sowie des Vienna Center for Quantum Science and Technology (VCQ) konnten nun ein Bild mit roten Photonen gewinnen, obwohl diese nie in der Nähe des Objekts waren. Dieses Abbildungsverfahren, das die verblüffenden Möglichkeiten der Quantenphysik auf neuartige Weise nutzt, könnte in der Medizin Anwendung finden. Die ForscherInnen publizieren dazu im renommierten Fachmagazin “Nature”. (more…)
AUSTIN, Texas — A team of researchers at the Cockrell School of Engineering at The University of Texas at Austin has developed a tiny, low-power device that mimics a fly’s hearing mechanism.
The new device could be used to build the next generation of hypersensitive hearing aids with intelligent microphones that adaptively focus only on those conversations or sounds that are of interest to the wearer. (more…)
Wrongly ID’d since ’74, Only Three Specimens Known
Collectors found the first two specimens of the prickly plant in 1974 and 1990 in west Texas. Then, for two decades, the 14-inch-tall plant was identified wrongly as one species, then another and then a third. (more…)
Scientists have found the fossilized remains of the brain of the world’s earliest known predators, from a time when life teemed in the oceans but had not yet colonized the land.
An international team of paleontologists has identified the exquisitely preserved brain in the fossil of one of the world’s first known predators that lived in the Lower Cambrian, about 520 million years ago. The discovery revealed a brain that is surprisingly simple and less complex than those known from fossils of some of the animal’s prey. (more…)
ANN ARBOR — In chambers that mimic Mars’ conditions, University of Michigan researchers have shown how small amounts of liquid water could form on the planet despite its below-freezing temperatures.
Liquid water is an essential ingredient for life as we know it. Mars is one of the very few places in the solar system where scientists have seen promising signs of it – in gullies down crater rims, in instrument readings, and in Phoenix spacecraft self portraits that appeared to show wet beads on the lander’s leg several years ago.
