Are gun owners more or less afraid than people who do not own guns? A new study from researchers at Florida State University and the University of Arizona hopes to add some empirical data to the conversation after finding that gun owners tend to report less fear than non-gun owners.
The study, led by sociology doctoral student Benjamin Dowd-Arrow, used the Chapman University Survey of American Fears to examine both the types and the amount of fear that gun owners had in comparison to non-gun owners.
Fossil animal droppings, charcoal from ancient fires and bone fragments litter the ground of one of the world's most important human evolution sites, new research reveals.
The latest evidence from southern Siberia shows that large cave-dwelling carnivores once dominated the landscape, competing for more than 300,000 years with ancient tribes for prime space in cave shelters.
A team of Russian and Australian scientists have used modern geoarchaeological techniques to unearth new details of day-to-day life in the famous Denisova Cave complex in Siberia's Altai Mountains.
Study Highlights:
A simple test of walking speed may be a reliable tool to evaluate whether young stroke survivors are ready to return to work.
Walking faster than 3 feet per second predicted a stroke survivor's likelihood of returning to work.
DALLAS, Sept. 26, 2019 -- A simple walking speed test may help predict whether young adult stroke survivors are ready to return to work, according to new research published in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.
Scientists have confirmed for the first time that bacteria can change form to avoid being detected by antibiotics in the human body.
Studying samples from elderly patients with recurring urinary tract infections, the Newcastle University team used state-of-the art techniques to identify that a bacteria can lose its cell wall - the common target of many groups of antibiotics.
CAMBRIDGE, MA -- Our brains contain millions of synapses -- the connections that transmit messages from neuron to neuron. Within these synapses are hundreds of different proteins, and dysfunction of these proteins can lead to conditions such as schizophrenia and autism.
One fundamental problem of quantum electrodynamics is the fate of the superheavy atomic nucleus, which is proposed to collapse when the atomic number exceeds certain value. However, this intriguing supercritical collapse phenomenon remains elusive in experiments. Discrete scale invariance (DSI) is a scale anomaly with the violation of the continuous scale symmetry. The intriguing log-periodicity is the characteristic signature of DSI, which exists in rupture, growth processes, turbulence, finance, and so on.
A research team led by Dr Xiang David Li, Associate Professor from the Department of Chemistry, in collaboration with Dr Karen Wing Yee Yuen from the School of Biological Sciences and Dr Jason Wing Hon Wong from the School of Biomedical Sciences at The University of Hong Kong (HKU), revealed a new fundamental mechanism by which a cell can make necessary changes in its chromatin structure in response to different DNA-associated processes such as gene expression and DNA damage repair. The findings were recently published in the prestigious scientific journal Molecular Cell.
WASHINGTON, D.C., September 25, 2019--Substantial school spending cuts triggered by the Great Recession were associated with sizable losses in academic achievement for students living in counties most affected by the economic downturn, according to a new study published today in AERA Open, a peer-reviewed journal of the American Educational Research Association.
In a first-of-its-kind study, Children's Hospital Los Angeles researchers piece together a road map of typical brain development in children during a critical window of maturation. The study shows how a "wave of brain maturation" directly underlies important social and behavioral changes children develop during the transition from childhood to adolescence.
CLEVELAND, Ohio (September 24, 2019)--Thanks to increased media attention, sexual assaults occurring in the military are finally getting the attention they deserve. However, most reports involve reproductive-aged women Veterans from recent service eras. A new study confirms the problem has a long history with assaults linked to numerous mental and physical problems. Study results will be presented during The North American Menopause Society (NAMS) Annual Meeting in Chicago, September 25 to 28, 2019.
CINCINNATI -- Three new studies by scientists at Cincinnati Children's Hospital Medical Center, in collaboration with researchers at the University of Cincinnati, highlight the relationship between air pollution and mental health in children.
Children with asthma have a higher likelihood of also suffering from anxiety and depression, and when all three conditions are present, patients are almost twice as likely as those with asthma alone to seek care in the Emergency Room.
CORVALLIS, Ore. - Ocean-based actions have greater potential to fill in gaps in climate change mitigation than previously appreciated, an Oregon State University scientist and two co-authors explain in a paper published today in Science.
The article by OSU distinguished professor Jane Lubchenco and her collaborators aims to connect the dots between two new international reports, one highlighting the devastating impact of climate change on the ocean, the other an analysis of ocean-related solutions to climate change.
PITTSBURGH, Sept. 25, 2019 - The research community is increasingly recognizing video as more than just a medium to disseminate scientific findings after a study's conclusion. A powerful tool, film can engage study participants and become an integral part of the scientific process, when deployed thoughtfully.
To guide this emerging practice, University of Pittsburgh Graduate School of Public Health scientists performed the first review of studies on use of film in public health research, reporting their findings in the journal Qualitative Health Research.
Artificial intelligence (AI) appears to detect diseases from medical imaging with similar levels of accuracy as health-care professionals, according to the first systematic review and meta-analysis, synthesising all the available evidence from the scientific literature published in The Lancet Digital Health journal.
