Scientists surveying ocean floor turn up new fish off Alaska

ANCHORAGE, Alaska (AP) — Federal biologist Jay Orr never knows what's going to come up in nets lowered to the ocean floor off Alaska's remote Aleutian Islands, which separate the Bering Sea from the rest of the Pacific Ocean. Sometimes it's stuff he has to name.

Trump's denial of climate science at odds with world leaders

WASHINGTON (AP) — If elected president, Donald Trump would be the only head of state in the world to contend that climate change is a hoax, according to a study.

Prenatal Multivitamins Don't Help Much, Study Says

For pregnant women, taking prenatal vitamins may be a waste of money, a new review of previous research suggests. Instead of taking multivitamin and mineral supplements, pregnant women should focus on improving the overall quality of their diets, and should take just two vitamins: folic acid and vitamin D, according to the review, conducted by researchers in the United Kingdom. "We found no evidence to recommend that all pregnant women should take prenatal multinutrient supplements beyond the nationally advised folic acid and vitamin D supplements, generic versions of which can be purchased relatively inexpensively," the authors wrote in the report, published today (July 11) in the journal Drug and Therapeutics Bulletin.

Too Many People 'Self-Prescribe' Antibiotics, Experts Say

Many Americans store leftover antibiotic drugs in their homes and say that if they got sick, they would take the antibiotics without going to their doctor first, a new study finds. The findings are troubling, experts say, in part because when people self-diagnose and treat themselves, they often end up taking antibiotics when they don't need to, which may further the spread of antibiotic resistance, the researchers said. "When people self-diagnose and self-prescribe antibiotics, it is likely that the therapy is unnecessary, because most often, these are upper-respiratory infections that are mostly caused by viruses," study researcher Dr. Larissa Grigoryan, an instructor of family and community medicine at Baylor College of Medicine in Texas, said in a statement.

Zoo aims to help chimps hang on to their wild side

University of Birmingham researchers have introduced a forest canopy-like environment in the chimpanzee enclosure at Twycross Zoo using the software, which provides data on wild chimpanzee behavior and allows researchers to analyze changes. "A key part of the tool is that it's based on replicating the mechanical challenges that chimpanzees experience in the wild in their daily lives," Susannah Thorpe, senior lecturer at the University of Birmingham, told Reuters. "So when they're moving around forest canopy they have to deal with branches flexing under their weight, they have to deal with planning routes in advance so they know where to go to get to the next food source and we're trying to emulate these mechanical challenges into the lives of captive chimpanzees." Straps and other structures have been installed to make the chimps bend and move around off the ground.

Simian Stone Age: Monkeys Used Rocks as Tools for Hundreds of Years

A group of wild capuchin monkeys in Brazil have used stones as tools to prepare their favorite meal of cashew nuts for more than 700 years, according to a new study. Archaeologists found evidence that capuchin monkeys in Brazil?s Serra da Capivara National Park have used stones to smash open the shells of cashew nuts and seeds for at least 100 monkey generations. The researchers observed young monkeys learning to use stones as tools from older monkeys at recognizable "cashew-processing sites," such as around the base of a cashew tree.

Evidence of Cannibalism: Did Neanderthals Eat Each Other?

Neanderthal bones uncovered in a Belgium cave show unmistakable signs of butchery, and scientists said they are the first evidence of Neanderthal cannibalism in northern Europe. "The big differences in the behavior of these people on the one hand, and the close genetic relationship between late European Neanderthals on the other, raise many questions about the social lives and exchange between various groups," Hervé Bocherens, one of the lead researchers, told CBS News.

Raytheon cautiously optimistic on satellite control station

Raytheon Co on Tuesday said it was cautiously optimistic after hitting key milestones in recent months on a long-delayed and over-budget program to develop a ground control system for next-generation GPS satellites. Wajsgras said Raytheon would continue to work closely with the U.S. Air Force to ensure the success of the program, which is facing a "live or die" Pentagon review after breaching critical cost thresholds earlier this year. "We feel good about the progress we've made." Defense Undersecretary Frank Kendall told reporters this week that Raytheon's work on the program was "a mixed bag", showing progress in some areas but continuing problems in others.
