Chiropractic, homeopathy, acupuncture, juice diets, and other forms of unproven alternative medicine cannot cure cancer, no matter what some quacks might claim.
Unfortunately, vulnerable cancer patients turn to these charlatans every year rather than visit real doctors, hoping for a miracle treatment to purge them of their monstrous disease. But as a new study published in the Journal of the National Cancer Institute makes painfully clear, as a treatment for cancer, alternative medicine does not cure; it kills. A team of scientists from Yale University perused the National Cancer Database, a collection of 34 million records of cancer patients along with their treatments and outcomes, to identify patients who elected to forgo conventional cancer treatments like chemotherapy, radiotherapy, and surgery in favor of alternative medicine. Why IQs Rise When Nations Experience Rapid Economic Development. By Louis Putterman Just in case you haven’t heard this before, I’ve got some information for you that you might find a bit troubling.
In their 2006 book titled IQ and Global Inequality, intelligence experts Richard Lynn and Tatu Vanhanen report that setting the average measured IQ in the U.K. at 100, people in the U.S. had average IQs of 100 and 98, respectively. People in the Central African Republic, Mali and Kenya had average IQs of 64, 69 and 72. People in India, Indonesians, and Iraq scored somewhat higher than those in the poorer countries but lower than those in the richer countries: their average IQs were 82, 87, and 87 respectively. Are country incomes and IQs correlated? Could this really be true?

New AI can work out whether you're gay or straight from a photograph. Artificial intelligence can accurately guess whether people are gay or straight based on photos of their faces, according to new research that suggests machines can have significantly better “gaydar” than humans.
The study from Stanford University – which found that a computer algorithm could correctly distinguish between gay and straight men 81% of the time, and 74% for women – has raised questions about the biological origins of sexual orientation, the ethics of facial-detection technology, and the potential for this kind of software to violate people’s privacy or be abused for anti-LGBT purposes. The machine intelligence tested in the research, which was published in the Journal of Personality and Social Psychology and first reported in the Economist, was based on a sample of more than 35,000 facial images that men and women publicly posted on a US dating website. “It’s certainly unsettling.

Se não conseguir dormir, levante-se. What's Really Warming the World? Climate deniers blame natural factors; NASA data proves otherwise. Climate scientists tend not to report climate results in whole temperatures. Instead, they talk about how the annual temperature departs from an average, or baseline.
They call these departures "anomalies. " They do this because temperature anomalies are more consistent in an area than absolute temperatures are. For example, the absolute temperature atop the Empire State Building may be different by several degrees than the absolute temperature at New York’s LaGuardia Airport. But the differences from their own averages are likely to be about the same. Estudo indica que jogos de tiro causam danos cerebrais.
