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. Now a new study has found that people with reduced kidney function may have an increased risk of developing dementia. The study is published in the May 5, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology.

A group of researchers at the Hong Kong University of Science and Technology (HKUST) has uncovered the mechanism of how DNA is being melted to start bacterial gene transcription and how one class of antibiotics inhibits this process - an important way in killing bacteria. This discovery provides useful insight on the development of new antibiotics for bacteria that is antimicrobial resistance.

Pediatric Academic Societies 2021 Virtual Meeting session will bring together policy and physician experts to predict major child health legislative and policy changes.

Researchers from the UCLA School of Dentistry have discovered a key molecule that allows cancer stem cells to bypass the body's natural immune defenses, spurring the growth and spread of head and neck squamous cell cancers. Their study, conducted in mice, also demonstrates that inhibiting this molecule derails cancer progression and helps eliminate these stem cells.

When light hits certain molecules, it dislodges electrons that then move from one location to another, creating areas of positive and negative charge. This "charge transfer" is highly important in many areas of chemistry, photosynthesis and semiconductor devices and solar cells. A new study reveals how a molecule's structure changes as charge is redistributed, with some chemical bonds getting longer and some shorter, before finally relaxing back into its original state.

New research from Carnegie Mellon University's Bin He demonstrates that noninvasive neuromodulation via low-intensity ultrasound can have cell-type selectivity in manipulating neurons.

Paid video streaming services on your television, smart phone or other devices are increasingly replacing traditional video entertainment platforms of cable, satellite and broadcast TV. The growth of these services, known in the industry as over-the-top (OTT) media services, may be accompanied by a rise in pirated content, particularly where access to those services may be restricted, a group of researchers has found.
