Smart dust: A complete computer that’s smaller than a grain of sand

"Nobody’s ever written a Star Trek episode about the world’s smallest microchip, only about the world’s smallest computer. Now, a team from the University of Michigan has built not just a very small microchip, but a whole functioning computer, and it’s less than a cubic millimeter in size. Called the Michigan Micro Mote, or M3, this tiny computer features processing, data storage, and wireless communication. Researcher Pabral Dutta thinks it will be the 'next revolution in computing.' The technology works with a very low-powered and low-range wireless standard to broadcast its latest state every few minutes. To power the M3, researchers fitted it with a tiny solar cell."

France announces e-cigarette ban, then French study finds e-cigarettes harmful

"French Health Minister Marisol Touraine announced in May that the ban on smoking in public places would be extended to cover electronic cigarettes, and that they would be subject to the same controls as tobacco. The move has sparked outrage among sellers and users of the battery-powered devices which contain liquid nicotine that is turned into a vapor when inhaled. Ms Touraine said: 'The e-cigarette is not an ordinary product. We need to apply the same measures as there are for tobacco. That means making sure it cannot be smoked in public places, that its sale is restricted to over 18s and that firms are not allowed to advertise the products.'" Continue reading →

UW Researcher Moves Another Human’s Finger with his Thoughts

"Many new studies have shown that people can control things -- like video games or a cursor on a screen -- only with their thoughts, but a new project takes this to the next level: people controlling other people with their thoughts. A new study by University of Washington researchers created the first human-to-human brain interface that is noninvasive. It allowed the thoughts of one researcher to manipulate movement of another. The study used electroencephalography (EEG) -- which is used to record brain activity noninvasively from the scalp -- and transcranial magnetic stimulation, which is a noninvasive way of delivering stimulation to the brain to obtain a response."

‘The U.S. effect’: Researchers encouraged to report exaggerated or eye-catching results

"Scientists who study human behaviour are more likely than average to report exaggerated or eye-catching results if they are based in the United States, according to an analysis of more than 1,000 research papers in psychiatry and genetics. This bias could be due to the research culture in the US, authors of the analysis said, which tends to preferentially reward scientists for the novelty and immediate impact of a piece of work over the quality or its long-term contribution to the field. One of the authors said that there was intense competition in the US for research funds and, subsequently, pressure to report novel findings in prestigious, high-impact scientific journals."

UK’s former top drug official: Coke-head bankers caused financial crisis

"The former top drugs adviser to Britain’s parliament told UK newspaper The Telegraph on Sunday that risk-taking behaviors behind the financial crisis of 2008 were driven by excessive cocaine consumption by the world’s banking elite. Nutt was fired from his post as Britain’s top drugs adviser in 2009, after he criticized the government’s drug policies for inhibiting research into Schedule I substances like psilocybin, which Nutt has studies for its potential to alleviate symptoms of depression. At the time he’d said that consuming the unadulterated, pure form of the drug ecstasy is safer than riding a horse. Nutt was ordered to apologize for his statement on ecstasy." Continue reading →

Plants use underground fungus network to send ‘distress signals’ to each other

"The scientists isolated the plants from each other above ground, covering them with bags and thereby preventing airborne chemicals (one form of plant communication) from traveling from one plant to the other. Then, the team introduced the aphids. In the plants that were connected by fungi, when a single plant was infected with aphids, the other two plants began to mount their chemical defenses, secreting aphid-repelling substances that also attract the wasps that feed on aphid larvae. The plants that were not connected by mycorrhizae were apparently not warned of the attack on the single plant in their group because they secreted no defensive chemicals." Continue reading →

Scientists: Plants communicate with one another through ‘nanomechanical vibrations’

"A study reveals that plants are able to communicate with each other even when light, scent and touch have been removed from the equation, leading scientists to speculate that there’s a wholly different mechanism they use to encourage each other’s growth. It’s long been known that planting basil near other species can tend to encourage its neighbor’s growth, and it’s not new that plants communicate with each other through shade, chemical smells, root structures and other forms of touch. By planting chili pepper next to basil, then separating them from all known methods of plant interaction, the chili plant still grew as if it knew the basil was there." Continue reading →

Egyptian iron artifacts, earliest ever found, made from meteorite

"The earliest iron artefacts ever found — funeral beads strung around bodies in a 5,000-year-old Egyptian cemetery — were made from a meteorite, archaeologists said on Monday. The nine small beads come from two burial sites dated to around 3,200 BC, where they were found in necklaces along with exotic terrestrial minerals such as lapis lazuli, agate and gold. X-ray scanners, meanwhile, showed that the meteorite iron had been repeatedly heated and hammered to make the precious jewels for the afterlife. This shows that in the fourth millennium BC, the Egyptians were already advanced in the art in smithing, say the researchers." Continue reading →

Scientists release test to combat counterfeiting of legendary ‘cat poop’ coffee

"The Asian palm civet eats coffee cherries, the fruit of the coffee plant. They digest the soft fruit and excrete the seeds in their feces, which, according to connoisseurs, gives the coffee a flavor unlike any other in the world. The fact that people will pay exorbitant amounts for real Kopi Luwak has led to a thriving black market in fake Kopi Luwak. Some people sell regular coffee beans and claim they are the famous civet coffee. Others adulterate Kopi Luwak beans with regular coffee beans, hoping drinkers won’t notice the inferior quality. Scientists have developed a test that checks for the unique chemical fingerprint on Kopi Luwak." Continue reading →

Can You 3-D Print An Airplane?

"It’s a new phase in the 3-D printing revolution. 'We’re transitioning now to a stage where not only can the machine make something, but the machine can actually make its own parts,' said Gershefeld. Rather than laying down materials flatly, layer after layer, it will be possible to print stronger, interlocking parts that build into huge structures. Just as pixels of different colors come together to form a picture, 3-D pixels will come in different 'colors' or shapes. It’s incredible. If a simple 'Can you 3-D print an airplane?' leads down the road to such innovation, imagine what other inventions are stemming from other questions." Continue reading →
