Fat inside body worse for health, study says

Health
Feb. 1 (UPI) -- The fat that poses the biggest danger to a person's health isn't visible outside of the body, but inside of it, a new study says. Exercise and medicine are the most helpful for getting rid of visceral fat, according to a study published Friday in Mayo Clinic Proceedings. "Visceral fat can affect local organs or the entire body system. Systemically it can affect your heart and liver, as well as abdominal organs," said Ian J. Neeland, assistant professor of internal medicine University of Texas Southwestern Medical Center and study senior author, in a press release. "When studies use weight or body mass index as a metric, we don't know if the interventions are reducing fat everywhere in the body, or just near the surface." Visceral fats are also known as an "active organ," w...
Possible building block of life detected inside distant star

Possible building block of life detected inside distant star

Science
Jan. 23 (UPI) -- Scientists have detected the prebiotic molecule glycolonitrile inside a distant star for the first time. Researchers think the molecule may have played a role in the emergence of life on Earth. Glycolonitrile is considered an important precursor to adenine, one of the nucleobases that forms both DNA and RNA. Astronomers detected the organic chemical's signature inside a solar-type protostar named IRAS16293-2422 B. By studying the chemical makeup of infant stars, still enveloped by a thick blanket of gas and dust, scientists can gain a better understanding of how the chemical ingredients necessary for life come to exist inside a young stellar system. Researchers in Europe and the United States were able to locate glycolonitrile among the spectral signature recorded by the ...

Seeing but not believing: Inside the business of 'deepfakes'

Technology
In a video seen by millions, a man that looks and sounds just like President Obama gives an address. But instead of a polished speech, he spouts out controversial opinions -- and even a curse word. A split screen reveals that it's not our 44th president making these comments after all -- but actor and frequent Obama impersonator, Jordan Peele. In a Buzzfeed production, Peele imitates Obama's voice with video manipulation to match. It's what's called a "deepfake" -- a video created with artificial intelligence used to convert video of real people into potentially damaging doppelgangers, appearing to say and do things the real people never actually did. In this case, it's Peele and Buzzfeed using the technology to create an sort of PSA, and reveal their trick to the viewer at the end. B...
Neuroscientists identify the origins of 'free will' inside the brain

Neuroscientists identify the origins of 'free will' inside the brain

Science
Oct. 2 (UPI) -- Neuroscientists have pinpointed the origin of "free will" inside the human brain. Whether or not free will exists -- or whether such a distinction is meaningful -- will remain a point of contention among priests and philosophers. What matters to neuroscientists is the interpretation, or perception, of free will. And for the first time, scientists have identified its cognitive origins. Scientists define free will as the combination of volition, the will to act and agency, a sense of responsibility for one's actions. Through an analysis method called brain lesion network mapping, scientists were able to pinpoint the origins of the two cognitive processes responsible for the perception of free will. "Lesion network mapping is a recently validated technique that allows scient...
Inside the horrors of the Jonestown massacre, the day 918 Americans died

Inside the horrors of the Jonestown massacre, the day 918 Americans died

World
Tim Carter was in a state of absolute shock. He had been told to go on an errand in the midst of a big, hastily-called church meeting at the pavilion inside the Jonestown compound in the Guyanese jungle where he had been living for several months. When he returned to the pavilion, he found hundreds of people -- neighbors, friends, his wife and baby -- dead or dying, engaged in the largest ritual mass-murder suicide in history. "What I saw and heard were people screaming," Carter said. "There were people crying ... I know what I heard, and it was not some kind of joyful experience. That's a fact." Watch "Truth and Lies: Jonestown - Paradise Lost" on Friday, Sept. 28 at 8 p.m. ET on ABC. It was Nov. 18. 1978, and the bodies of more than 900 Americans were spread across the grounds o...
