It's been 40 years since NASA launched Apollo 17, its final human mission to the moon. The commander of that mission says he'd love to give up his claim to fame as "the last man on the moon" but concedes that it probably won't happen in his lifetime. And future trips might be run by companies in the private sector.
Countries attending U.N. climate talks were not able to come up with any major agreements on reducing carbon emissions and slowing global warming. This comes after the World Bank issued a report predicting global temperatures could rise by 7.2 degrees Fahrenheit by the end of the century — possibly sooner if current promises to curb emission are not kept. Renee Montagne talks about this with World Bank President Jim Yong Kim.
Researchers found a surprising number of mutations, including several associated with disease, in the genes of normal healthy people. Their study raises questions about whether widespread genetic sequencing could end up scaring people for no good reason.
Although we can usually smell when food goes bad, humans just don't have the fruit fly's direct path from nose to brain that alerts it to food poison. But the detection of this pathway could someday lead to more research that could help us develop better bug repellants.
What a person remembers of a meal hours later, not the actual calories consumed, matters more when it comes to hunger. Eating while watching TV sets us up to eat more food than we should, but a new experiment shows how manipulating our memories of a meal can change how hungry we feel.
New research suggests older adults may have less activity in the area of the brain that processes risk and subtle danger. Another possible reason older adults don't pick up on warning signs is an increasing bias against negativity.
A study in Newark, N.J., found that homicides committed over a quarter century spread out very much like an infectious disease epidemic. Using this information, cities might be able to predict when and where murders will occur.
