A new report, commissioned by the federal government, finds the field is rife with poorly done studies, misdiagnoses and tests that can give misleading results.
While there is no doubt that people can be allergic to certain foods, with reproducible responses ranging from a rash to a severe life-threatening reaction, the true incidence of food allergies is only about 8 percent for children and less than 5 percent for adults, said Dr. Marc Riedl, an author of the new paper and an allergist and immunologist at the University of California, Los Angeles.
Yet about 30 percent of the population believe they have food allergies. And, Dr. Riedl said, about half the patients coming to his clinic because they had been told they had a food allergy did not really have one.
Dr. Riedl does not dismiss the seriousness of some people’s responses to foods. But, he says, “That accounts for a small percentage of what people term ‘food allergies.’ “‘ (New York Times )
Scientists in China have succeeded in teleporting information between entangled photons further than ever before — 16 km (10 miles), much further than the few hundred meters previously achieved — bringing us closer to transmitting information over long distances without the need for a traditional signal.’ (KurzweilAI.net)
Bush’s former strategist is secretly seizing control of the GOP: ‘One afternoon in late April, Karl Rove welcomed an elite group of conservative political operatives and moneymen into his home in Washington, D.C. Along with his protégé Ed Gillespie, who succeeded him as George W. Bush’s top political adviser, Rove had gathered together the heavyweights of the GOP’s fundraising network. In attendance were the political director of the U.S. Chamber of Commerce, as well as the leaders of two new megadollar campaign groups loyal to Rove: American Crossroads and the American Action Network. Rove’s plan was straightforward: to seize control of the party from Michael Steele, whose leadership of the Republican National Committee was imploding in the wake of a fundraiser at a lesbian bondage club. By building a war chest of unregulated campaign cash – an unprecedented $135 million to be raised by these three groups alone – Rove would be able to wage the midterm elections on his own terms: electing candidates loyal to the GOP’s wealthiest donors and corporate patrons. With the media’s attention diverted by the noisy revolt being waged by the Tea Party, the man known as “Bush’s brain” was staging a stealthier but no less significant coup of the Republican Party.’ (Rolling Stone)
Researchers at government institutions in the U.S. have created a vaccine that successfully immunises monkeys against the two most lethal strains of the disease, and have found that it also protects against a newer strain not represented in the vaccine.’ (Cosmos)
‘”The Star That Ate My Planet” may sound like a B-grade science fiction movie title, but this is really happening 600 light-years away. Like a moth in a candle flame, a doomed Jupiter-sized planet has moved so close to its sunlike parent star that it is spilling its atmosphere onto the star. This happens because the planet gets so hot that its atmosphere puffs up to the point where the star’s gravity pulls it in. The planet will likely be completely devoured in 10 million years. Observations by Hubble’s new Cosmic Origins Spectrograph measured a variety of elements in the planet’s bloated atmosphere as the planet passed in front of its star. The planet, called WASP-12b, is the hottest known world ever discovered, with an atmosphere seething at 2,800 degrees Fahrenheit.’ (HubbleSite)
‘I was intrigued by the “mind reading” aspects of vision. In a nutshell, how does this work, and how do humans benefit from this ability?’
‘Our color vision fundamentally relies upon the cones in our retina, and I argue in my research that color vision evolved in us primates for the purpose of sensing the emotions and states of those around us. We primates have an unusual kind of color vision – our cones sample the visible spectrum in a peculiar fashion – and I have shown that one needs that kind of peculiar color sense in order to pick up the color modulations that occur on our skin when we blush, blanch, redden with anger, and so on. Our funny primate variety of color vision turns out to be optimized for seeing the physiological modulations in the blood in the skin that underlies our primate color signals.
So, we evolved special mechanisms designed for sensing the emotions and states of others around us. That sounds a lot like the evolution of a “mind-reading” mechanism, which is why I (only half in jest) describe it that way.’ (N e u r o n a r r a t i v e)
