Can cell phones increase the risk of tumors? | Digital Trends Spanish

Research carried out by the University of Berkeley in California establishes a strong link between radiation from mobile phones and tumors, especially in the brain. The researchers analyzed the statistical results of 46 different studies carried out around the world and found that using a cell phone for more than a thousand hours, that is, about 17 minutes a day for a period of ten years, increased the risk of developing tumors in 60 percent. The study leaders also indicated that mobile phone use for ten years or more doubled the risk of brain tumors. "The use of the mobile phone highlights a series of public health problems to which, unfortunately, the scientific community has paid little attention," says Joel Moskowitz, director of the Center for Family and Community Health at the Sch...

We are born with the brain “prewired” to see words | Digital Trends Spanish

Human beings are born with a part of our brain that is "pre-wired" to be receptive to words and letters, thus paving the way for us to later learn to read, says a new study. The researchers found this sector of the brain, called the word form visual area (VWFA), by analyzing brain scans of newborns. "That makes it fertile ground to develop a sensitivity to visual words, even before any exposure to language," said Zeynep Saygin, lead author of the study and assistant professor of psychology at the Ohio State University. In the study, which was published this October 22 in Scientific Reports, the researchers analyzed MRI scans of the brains of 40 newborns, all less than a week old. They compared them to similar scans of 40 adults. The VWFA would be next to another part of the visual ...

They discover the seat of male sexual desire in the brain | Digital Trends Spanish

A major study conducted by Northwestern Medicine has discovered where male sexual desire is located in the brain. The scientific team in charge of this research was led by Dr. Serdar Bulun. According to their findings, published in Endocrinology, the seat of sexual desire in men would be found in specific regions of brain tissue, where a key gene called aromatase is present, according to research carried out in mice. This gene regulates male sexual behavior, so it could be stimulated to increase its function in case of low sexual desire, or it can be conditioned with drugs when you have a compulsive sexual desire, according to scientists. Aromatase converts testosterone to estrogen in the brain, which drives male sexual activity. Previously, the full function of aromatase in the ...

Dogs process words like humans | Digital Trends Spanish

An interesting study published this August 3 in Scientific Reports indicates that dogs just as humans manage to process spoken language in a hierarchical way on two levels, thus assimilating the meanings and intonations of what their masters tell them. To carry out the research, scientists from the Eötvös Loránd University in Hungary used fMRI brain images of 12 companion dogs between the ages of 2 to 10 years from three different breeds. There were six border collies, five golden retrievers, and a German Shepherd. There they could distinguish what they called emotional prosody, a term used by researchers to describe the emotional feelings associated with the different inflections used in dog-directed speech. How does this experiment work to detect hierarchies in word...
