Scientists Take Graphene to the Next Level

"Graphene! Graphene! Miracle of miracles! Savior of technology! At least, that’s been the chatter for the last nine or so years, ever since scientists isolated the single-atom-thick carbon derivative. According to a post today in MIT Technology Review, a group of really smart people appear to have solved a major problem with using graphene in transistors by making it act like a switch. There used to be a lot of hand-wringing that we were running up against the upper limits of Moore’s Law when it came to processing power. If we’re talking about silicon, that may be true. But if this graphene stuff is legit, tomorrow’s processors will make today’s look as they were made by Fisher-Price." Continue reading →

Man gets drunk randomly because his own body brews beer from carbs

"A Texas man who was struggling with episodes of sudden and unexplained drunkenness was found to have alcohol-producing microbes in his gut, which were busily making beer. Health care workers were baffled. Initially they assumed that the man was being dishonest and was drinking on the sly. They checked the patient in to a hospital room for 24 hours and made absolutely sure that he had not smuggled in any alcohol. They fed him foods rich in carbohydrates. Sure enough, his blood alcohol content began to spike on its own. The man, who was an avid home brewer, had an abundance of brewer’s yeast in his gut, making his intestines act as their own small brewery." Continue reading →

Pot And Pregnancy: It’s Harmless, So Why Are Moms Still Prosecuted?

"Weighing decades of research, it’s fairly safe to say that marijuana during pregnancy has very little to no effect on the developing fetus. Unfortunately, child welfare laws in many states do not agree. Some states equate smoking marijuana while pregnant — whether to alleviate nausea, vomiting, stress or depression — with felony child neglect or abuse. Given that marijuana is the most widely used drug by women of child-bearing age, and the potential for women to use marijuana without knowing they’re pregnant, this is a women’s rights issue. Why should a woman surrender autonomy over her body, her children and her approach to motherhood to civil authorities, whether she uses cannabis or not?" Continue reading →

Toshiba’s quantum cryptography network that even the NSA can’t hack

"A quantum network uses specially polarized photons to encode an encryption key—a very long series of numbers and letters that can unlock a digital file. The photons are then sent down a fiber optic cable until they reach their destination, a photon detector, which counts them, and delivers the key to the intended recipient. If the photons are interfered with, the individual packets of information are forever altered and the recipient can see the telltale signs of tampering. The next step toward mainstreaming quantum crypto is increasing the distance that photons can travel before they degrade—currently the record is 200 km (124 miles) using a dedicated fiber optic cable."

Turn Your Desk Into a Pharmaceuticals Factory

"The Week's Chris Gayomali frets that '[t]oday's primitive psychedelics and artificial mood-boosters may be just the beginning' once 3D printing transforms chemical engineering. The Customs Minister from the land o' hobbits, Maurice Williamson, worries on Radio New Zealand, 'If people could print off ... sheets of Ecstasy tablets at the party they're at at that time, that just completely takes away our border protection role in its known sense.' Cronin, among others, suggests that controlling the 'chemical ink' is the key to preventing DIY recreational chemistry with 3D printers. But much current research uses bathroom sealant as the ink, and that's not the easiest material to restrict." Continue reading →

Taxpayers funding study of link between marijuana, domestic violence

"The National Institute on Drug Abuse, a part of the Department of Health and Human Services, is granting $1.86 million to the University of Buffalo’s Research Institute on Addictions to investigate the drug’s link to aggression. The study will run from 2013 to 2017 and will follow couples in which one or both partners use marijuana to determine whether its use 'results in affective, cognitive, or behavioral effects consistent with partner aggression.' NIDA has a $1.05 billion budget for 2013 and has publicly acknowledged that it does not fund research into the potential benefits of medical marijuana." Continue reading →

Harvard Study: No Correlation Between Gun Control and Less Violent Crime

"The authors of the study conclude that the burden of proof rests on those who claim more guns equal more death and violent crime; such proponents should 'at the very least [be able] to show a large number of nations with more guns have more death and that nations that impose stringent gun controls have achieved substantial reductions in criminal violence (or suicide).' But after intense study the authors conclude 'those correlations are not observed when a large number of nations are compared around the world.' In fact, the numbers presented in the Harvard study support the contention that among the nations studied, those with more gun control tend toward higher death rates." Continue reading →

Radio wave-treated water could change agriculture as we know it

"A groundbreaking new Irish technology which could be the greatest breakthrough in agriculture since the plough is set to change the face of modern farming forever. The technology – radio wave energised water – massively increases the output of vegetables and fruits by up to 30 per cent. Not only are the plants much bigger but they are largely disease-resistant, meaning huge savings in expensive fertilisers and harmful pesticides. Extensively tested in Ireland and several other countries, the inexpensive water treatment technology is now being rolled out across the world. The technology makes GM obsolete and converts excess CO2 into edible plant mass." Continue reading →

Ambient Backscatter Energy Harvester

"Ambient Backscatter transforms existing wireless signals into both a source of power and a communication medium. It enables two battery-free devices to communicate by backscattering existing wireless signals. Backscatter communication is orders of magnitude more power-efficient than traditional radio communication. Further, since it leverages the ambient RF signals that are already around us, it does not require a dedicated power infrastructure as in RFID." Continue reading →

Energy harvester that creates power from ambient vibrations comes to market

"MicroGen’s energy harvester, dubbed Bolt, provides power like a battery — but uses a very different means to get there. Housing a piezoelectric microelectromechanical system (MEMS) inside the casing pictured above, the unit creates energy from vibrations in the surrounding environment. Ambient vibrations cause a flap on the device (pictured below) to move back and forth, which in turn creates a current that dumps energy in to either a capacitor or a thin rechargeable battery next to the flap. The Bolt requires a source vibrating at around 120Hz in order to charge, and an LED on the outer casing will blink to let you know it’s full." Continue reading →
