Whether you are a morning person or a night owl may be influenced by genes connected to the circadian rhythm, a new study suggests. In a paper published in Nature Communications, researchers from consumer genetics company 23andMe and San Jose State University report the discovery of 15 gene regions linked to our preference for or against "morningness."

deodorant-020316.jpg According to new research, the type of antiperspirant you use determines the type and quantity of the thousands of bacteria species that live on your skin. 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.

marijuana-020216.jpg Those who habitually use marijuana could experience declines in verbal memory later in life, according to a new study from researchers at the University of Queensland in Australia and Kings College, London. For the study the researchers collected data from the Coronary Artery Risk Development in Young Adults (CARDIA).

pinkribbon-020216.jpg Those who consume a diet high in fiber earlier in life may be at a decreased risk for breast cancer, according to new data collected from the Harvard T.H. Chan School of Public Health. For the study the researchers collected data from 90,534 participants of the Nurse's Health Study II. The researchers found that the breast cancer risk was 12-19 percent lower for women who ate these diets.

Scientists may be inching closer to a better understanding of what causes schizophrenia. The new study, from researchers at Harvard Medical School, Boston Children's Hospital and the Broad Institute, looked closely at a brain process called synaptic pruning. This process sheds redundant connections between neurons in the brain over the course of a lifetime.

A new wearable electric eye patch may help reduce some symptoms for PTSD suffers, according to researchers at the Semel Institute for Neuroscience and Human Behavior at UCLA's David Geffen School of Medicine in Los Angeles. The small electric patch sends jolts of electricity into the eye while a patient is sleeping and enables a treatment referred to as "trigeminal nerve stimulation" (TNS).

Sleepwoman-012916.jpg Overuse of social media could have a negative impact on sleep cycles, according to a new study from researchers at University of Pittsburgh School of Medicine. For the study the researchers collected data from 1,800 U.S. citizens between the ages of 19 and 32. They found that overall the respondents spent an average of 61 minutes a day on social media sites.

Coffee-012916.jpg Regularly consuming moderate amounts of caffeine is not linked with increased risk for heart palpitations, according to a new study from researchers at UC San Francisco. For the study the researchers collected data from 1,388 participants from the National Heart, Lung, and Blood Institute (NHLBI) database. They tested the heart beats of heavy caffeine consumers over the course of one year.

Some forms of colorectal cancers could be found before standard screening begins at the age of 50, according to a new study from researchers at the University of Michigan in Ann Arbor. For the study the researchers examined records from 258,000 people in the colorectal cancer registry between the years of 1998 and 2011.

hookah-012616.jpg The secondhand smoke exposed to workers in hookah bars may be as dangerous as that from regular cigarette smoke, according to a new study from researchers at the NYU Langone Medical Center. For the study the researchers collected air samples from during work shifts of ten hookah bar workers. They found that the air showed similar pollutants to cigarette secondhand smoke.

Labrador-012616.jpg A strain of dog flu is quickly spreading across the U.S. this flu season, according to data released by the Washington Animal Disease Diagnostic Laboratory and the American Veterinary Medical Association (AVMA). According to the AVMA, the outbreak started in Chicago in April and the specific thread of flu is the H3N2 virus.
