Current guidelines for managing osteoporosis specifically call out hip or spine fractures for increasing the risk for subsequent bone breaks. But a new UCLA-led study suggests that fractures in the arm, wrist, leg and other parts of the body should also set off alarm bells. A fracture, no matter the location, indicates a general tendency to break a bone in the future at a different location,

A study involving researchers at Karolinska Institutet and Gothenburg University in Sweden has found that low levels of a protein called PDGFRb are associated with particularly good results of radiotherapy in women with early-stage breast cancer. The study, which is published in the journal Clinical Cancer Research, also suggests that the efficacy of radiotherapy can be improved with drugs that block this protein.

Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.

We here describe a new species of pelomedusoid turtle from a geological formation in Madagascar otherwise known for its exquisitely preserved fossil birds, dinosaurs, and crocodilians. The new turtle possesses an unusually flattened skull combined with a particularly gracile lower jaw and enlarged tongue bones, which not only must have given it a frog-like appearance, but also suggests that it was a specialized suction feeder that fed on small-bodied living prey using quick strikes.

Stress levels of moms with preschoolers soared during the pandemic, with twice as many of the mothers reporting they lost sleep during the COVID-19 outbreak than before it. Mothers, especially those with preschoolers, need a lot more than flowers on Mother's Day.... What moms really need is more support, from their family, workplaces and communities.

Consumers are less forgiving of brand failures when algorithms are anthropomorphized, use machine learning, or are used for subjective or interactive tasks.

The population growth of an endangered butterfly species is greatest in habitats with microclimatic variability, demonstrates a study carried out collaboratively by the Faculty of Biological and Environmental Sciences and the Helsinki Institute of Life Science of the University of Helsinki as well as the Finnish Environment Institute.

To improve our own health and the health of our planet, dietary habits will need to change. Because the composition of an optimal diet changes depending on the combination of location, season, and personalized dietary needs, investigators have built a tool that uses an extensive database of food items, nutrients, and environmental-impacts to develop optimized diets specific to an individual in a given country and month.

A new study published in the British Journal of Educational Technology has identified the different needs of students across primary, middle, and high school related to online learning during the COVID-19 pandemic.

When investigators in the UK recorded the calls of migratory birds called thrushes at night, they found that call rates were up to five times higher over the brightest urban areas compared with darker villages.

A new study provides a profile of teachers around the world who provide English Medium Instruction (EMI) in higher education, in which the English language is used to teach academic subjects (other than English itself) in countries where the first language is not English.

An analysis of published studies indicates that Twitter may be a useful learning tool in dental education.

Virtual care provided through telephone or videoconference has been broadly implemented in recent months because of the COVID-19 pandemic. A new analysis of published studies has examined the accuracy and reliability of virtual compared with in-person cognitive assessments for diagnosing dementia or mild cognitive impairment.

Erythropoietin (EPO) is a medication used to stimulate the production of new red blood cells, which is impaired in individuals with kidney failure. Unfortunately, however, the treatment may increase the risk of hip fractures.

Investigators found similarities in the bacterial composition of the mouth among patients with early rheumatoid arthritis and those at risk of developing the disease, compared with healthy individuals who were not at risk. The findings come from a study published in Arthritis & Rheumatology.

Untreated mental health disorders can be a serious problem for women and their children during pregnancy and after giving birth, during the postpartum period. A recent analysis funded by the Agency for Healthcare Research and Quality (AHRQ) and published in Psychiatric Research & Clinical Practice notes that few studies have examined the benefits of medications for mental health disorders in pregnant and postpartum women.

A new study published in Arthritis Care & Research indicates that few individuals with the autoimmune disease lupus who were publicly insured through Medicaid received recommended vaccines in 2000-2010. Also, those who were unvaccinated needed more acute care for vaccine-preventable illnesses.

A new study published in the British Journal of Clinical Pharmacology ¬provides insights on how common hospitalized patients develop liver injury from taking different medications.

Vitamin D is a critical part of a healthy diet. Among other benefits, it has been shown to protect against bone disease and maintain soft tissue health. A new study suggests that it may also play a role in the degree of postoperative pain postmenopausal women experience after undergoing total knee replacement. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

Chronic kidney disease is when a person's kidneys progressively lose their ability to filter waste from the blood and eliminate fluids.
