NASA spacecraft vaporized after crashing into the moon at 3,600 mph — as planned

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) – A robotic U.S. spacecraft ended a pioneering mission to map dust and gases around the moon with a planned, kamikaze crash into the lunar surface early on Friday, NASA officials said. The Lunar Atmosphere and Dust Environment Explorer, or LADEE, had been…

Scientist warns that the robot apocalypse really is coming unless steps are taken now

From HAL 9000 to the Terminator — all those Hollywood movies in which artificially intelligent robots end up turning on their human masters might not be too far from the truth. Noted artificial intelligence researcher Steve Omohundro published a paper in the April edition of the Journal of Experimental &…

Study: Global warming is due to carbon dioxide emissions, not chlorofluorocarbon

A paper published in the International Journal of Modern Physics B by the University of Waterloo’s Qing-Bin Lu last year claimed that solar activity and human chlorofluorocarbon (CFC) emissions, not carbon dioxide emissions, could explain the observed global warming over the past century. The journal has now published a rebuttal of that paper by myself…

Oklahoma students know less about evolution after Biology I than they did before taking it

A study published in the latest edition of Evolution: Education and Outreach demonstrated “the average student…completed the Biology I course with increased confidence in their biological evolution knowledge yet with a greater number of biological evolution misconceptions and, therefore, less competency in the subject.” The study, conducted by Tony Yates…

Life-giving vitamin B3 may have come from space on meteorites, NASA researchers say

Earth may have received vitamin B3 supplied by carbon-rich meteorites, according to NASA-funded researchers, supporting the theory that earthly life may have originated with extraterrestrial assistance. Vitamin B3, also known as nicotinic acid or niacin, is a precursor to compounds essential to metabolism, and has long been believed to have…

Kepler-186f: NASA discovers first Earth-sized planet orbiting in life-friendly zone

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) – For the first time, scientists have found an Earth-sized world orbiting in a life-friendly zone around a distant star. The discovery, announced on Thursday, is the closest scientists have come so far to finding a true Earth twin. The star, known as…

Cloning breakthrough: Scientists create patient-specific stem cells from adults’ skin tissue

By Sharon Begley NEW YORK (Reuters) – Scientists have moved a step closer to the goal of creating stem cells perfectly matched to a patient’s DNA in order to treat diseases, they announced on Thursday, creating patient-specific cell lines out of the skin cells of two adult men. The advance,…

Fox host Elisabeth Hasselbeck: Climate science is just a ‘product that’s sold’ to Americans

Fox News host Elisabeth Hasselbeck on Thursday morning declared that climate change was just another “product” being “sold” to the American people, which might explain why a recent study found that the network was wrong about the subject 72 percent of the time.
