The study, published in the journal PeerJ, involved 17 study participants. Three men and four women used antiperspirant products, three men and two women used deodorant, and three men and two women used neither product.

beard-020316.jpg Bacteria collected from beard hair may help to develop new antibiotics that may be able to kill off infection-promoting strains, according to new research. Dr. Adam Roberts, a microbiologist from University College London, collected samples from the beards of 20 different men and sorted through roughly 100 types of bacteria he found.

Surgical residents who allowed more flexible hours as opposed to standard duty hour-limits, did not have worse patient outcomes, according to a new study. The study, published in the New England Journal of Medicine, split 115 surgical residency programs at 148 affiliated hospitals into two groups for a noninferiority trial to test duty-hour rules.

terrierdog-020216.jpg Man's best friend may be able to read human body language in much the same way that humans do, according to a new study conducted by researchers at the University of Helsinki in Finland. The researchers found that dogs were specifically adept at reading the emotions linked with human facial expressions. For the study the researchers used eye movement tracking to collect data on 31 dogs.

bedbug-020216.jpg Bed bugs in some regions may be developing a resistance to insecticides, according to new data collected by New Mexico State University. For the study the researchers examined on isolated populations of bed bugs in both Michigan and Ohio. They found that these populations of bed bugs required insecticide concentrations that were about 1,000 times larger than other non-resistant bugs.

womensleep-012016.jpg Extra hours of "catch-up" sleep may help reduce the risk of type-2 diabetes that is commonly associated with sleep loss, according to researchers at the Sleep and Chronobiology Laboratory at the University of Colorado in Boulder. For the study the researchers examined a pool of healthy, lean men by first taking diagnostics after a week of normal sleep.

Ixodusricinus-011916.jpg Ticks carrying Lyme disease have been reported in more than 45 percent of U.S. counties, compared to 30 percent of counties in 1998, according to new research.

mixed-breed-011916.jpg A new study suggests that dogs can tell if their owners are happy or sad. The study, published in the journal Biology Letters, featured 17 domestic dogs of various breeds with images of human or dog faces showing expressions of either happiness or sadness. The sound of a bark or a human voice in Portuguese (a language that none of the dogs knew) was also played.

Children-marbles-011116.jpg Increased social interactions could be an integral part of having a longer life, according to a new study from researchers at University of North Carolina (UNC) at Chapel Hill.
