Suicide Rates May Rise After Natural Disasters

Content warning: This article discusses suicide and potential risk factors of suicide. Natural disasters can continue to cause pain long after homes have been rebuilt and businesses reopened. According to a recent U.S.-based study, rates of suicide increase somewhat during the first 3 years postdisaster. “These are, in a sense, preventable deaths.” “These […]

Geographic factors that affect HPV vaccination rates — ScienceDaily

Human papillomavirus (HPV) is the most common sexually transmitted infection, with an estimated 79 million Americans currently infected with the virus, according to the Centers for Disease Control and Prevention. If a high-risk HPV infection does not go away, it can lead to the development of a variety of cancers, including 91% of all cervical […]

European Colonists Dramatically Increased North American Erosion Rates

Everything wears away in time, but human activities like farming can dramatically accelerate natural erosion rates. The arrival of European colonists in North America, for instance, sped up the rate of erosion and river sediment accumulation on the continent by a factor of 10, according to a new study. An international team of […]

Study finds rising rates of food insecurity among older adults

From 2007 to 2016, food insecurity–or limited access to nutritious foods because of a lack of financial resources–increased significantly from 5.5% to 12.4% among older US adults, and the increase was more pronounced among individuals with lower income. The findings come from a study published in the Journal of the American Geriatric Society. The study, […]

Community spread of COVID-19 tied to patient survival rates at area hospitals

PHILADELPHIA and MINNETONKA, Minn. — High rates of COVID-19 in the county where a hospital is located appears to reduce survival rates among hospitalized patients with the virus, according to a new study from researchers in the Perelman School of Medicine at the University of Pennsylvania and at UnitedHealth Group. These findings were published in […]

A Robust Proxy for Geomagnetic Reversal Rates in Deep Time

North is north, until it isn’t. Earth’s magnetic field has repeatedly reversed itself, with magnetic north sometimes residing closer to today’s South Pole and vice versa. The time between these global-scale swaps has ranged from tens of thousands to millions of years, and the frequency of reversals may be linked to processes in […]

Electric ‘knob’ tunes chemical reaction rates in quantum gas — ScienceDaily

Building on their newfound ability to induce molecules in ultracold gases to interact with each other over long distances, JILA researchers have used an electric “knob” to influence molecular collisions and dramatically raise or lower chemical reaction rates. These super-chilly gases follow the seemingly counterintuitive rules of quantum mechanics, featuring exact units, or quanta, of […]

More than one in three respondents reported clinically significant levels of depression, exceeding rates seen before 2020 — ScienceDaily

Though childbirth is often anticipated with optimism and enthusiasm, approximately 10 to 20 percent of pregnant individuals also experience mental health challenges during the weeks immediately before and after birth. Depression, anxiety and trauma-related disorders can all be exacerbated by increased stress related to pregnancy and postpartum experiences. But it’s unknown how the stressors of […]
