In a new study, Yale researchers show that seeing tasks as a chance for children to learn reduces overparenting by about 50%. Parents are much less likely to intervene when their young children are getting dressed or performing other simple chores if those tasks are framed as learning opportunities, according to a new study by Yale researchers.

Yale physicist Eduardo H. da Silva Neto led an experiment that supports the existence of a new type of superconductor.

Most fatal pediatric opioid poisonings among children occur in their home with many following a history of maltreatment, a new Yale study finds. At least a quarter of children in the United States who died from opioid poisoning between 2004 and 2020 were victims of prior abuse or neglect, a new Yale study finds, and over two-thirds of 10- to 17-year-olds who suffered fatal poisonings had a history of substance use.

Ancient "gold" bug fossils, infused with pyrite, have been identified as a new species of arthropod.

Yale paleoanthropologist Jessica Thompson proposes guidelines for the ethical study of ancient human DNA. The study of ancient DNA provides valuable insights into human history, including how ancient populations migrated and merged with each other. But discoveries drawn from this ancient genetic data can directly impact the living in unexpected and even harmful ways.

Mental disorders can be characterized by many symptoms, but certain symptom combinations are more common than others, researchers find. Mental disorders like depression and anxiety are characterized by a variety of different symptoms, and individuals receiving the same diagnosis may experience different combinations of those symptoms.

An extended-release version of buprenorphine, a treatment for opioid use disorder, can be used earlier than other medication.

In a new study, Yale researcher Alison Sweeney found that giant clams in the Western Pacific may be the most efficient solar energy system on the planet. Solar panel and biorefinery designers could learn a thing or two from iridescent giant clams living near tropical coral reefs, according to a new Yale-led study.

When health care costs rise, employers outside the health care sector cut jobs, leading to higher unemployment among healthy middle-class wage earners. Rising health care prices in the U.S. are leading employers outside the health care sector to reduce their payroll and decrease their number of employees, according to a new study co-authored by Yale economist Zack Cooper.

Yale scientists say KL-50, their lead "chameleon" compound, effectively targets tumors without harming healthy surrounding tissue. In a new study, Yale researchers describe how a novel chemical compound attacks drug-resistant brain tumors without harming healthy surrounding tissue. The research, published in the Journal of the American Chemical Society , is a crucial step in the development of so-called "chameleon compounds" that may be used to target an array of pernicious cancers.

A new study co-authored by Yale economist Zack Cooper links rising prices for hospital care to lax antitrust enforcement.

A new Yale analysis of the economic toll of mental illness considers a host of adverse economic outcomes not considered in earlier estimates.

A new Yale study is the first to describe the shortand longer-term risk of hospital readmission for older persons who have had major surgery. A new Yale study finds an increased risk of hospital readmission for older Americans within 180 days of undergoing major surgery - a risk that is particularly acute for individuals who are frail or have dementia.

Non-medication-based treatments for opioid use disorder may be more harmful than no treatment at all, a new Yale study finds.

Recollections of traumatic events among people with PTSD trigger markedly different brain activity than when remembering sad or -neutral- experiences. It is well known that people who have lived through traumatic events like sexual assault, domestic abuse, or violent combat can experience symptoms of post-traumatic stress disorder (PTSD), including terrifying flashbacks, severe anxiety, and uncontrollable thoughts about the incident.

Helioscopus dickersonae lived in North America in the late Jurassic period, 100 million years earlier than any previously known early gecko relative.

Yale paleontologists have identified a -problematic- fossil as an ancient sea creature that lived in the plankton 420 million years ago. The mystery of Ezekiel's Wheel - the extinct sea creature, not the Biblical vision - may have taken its final turn, thanks to Yale paleontologists. In so doing, the researchers have also finally put a scientific name to the favorite fossil of a beloved amateur fossil hunter.

In a major new work, Yale ichthyologist Thomas Near revises branches of the Tree of Life concerning most fish species based on the latest scientific knowledge.

Air pollution has decreased across the U.S., but new research finds health burdens remain unequal among racial groups. Health benefits that have resulted from reductions in fine particulate air pollution aren-t distributed equally among populations in the U.S., a new Yale-led study finds. Racial and ethnic minorities - and Black people in particular - still experience disproportionately high rates of cardiovascular disease-related deaths caused by exposure to fine particulate matter, according to the research.

A group of researchers at Yale School of Medicine has found that levels of diversity of blood stem cells are determined during the development of the embryo. All humans have a diverse set of blood stem cell types which dictate the composition and function of our blood and immune cells and ultimately help govern overall health.

Transitioning to independent research is an important career junction in biomedicine. A new study finds women make this transition at lower rates than men.

Using a particular type of sedimentary rocks as their guide, researchers begin to tackle the question of when animals first appeared on Earth.

Yale researchers, colleagues say pandemic rise in proportion of Black prisoners highlights racial disparities in sentencing. The U.S. prison population plummeted during the early months of the COVID-19 pandemic but the percentage of incarcerated Black people rose, according to a new analysis of prison data published April 19 in the journal Nature.

Manufacturers, through a loophole in the law, can use an unsafe medical device as a basis for FDA authorization to bring it to market.

Yale researchers have uncovered a driver of the chronic inflammation that damages lungs in cystic fibrosis. It could be a target for treatment. Yale researchers have identified a possible driver of the persistent inflammation that causes irreversible lung damage in patients with cystic fibrosis, a genetic disorder that impairs breathing and digestion.

The Northern Treeshrew defies two of the most widely tested ecological -rules- of body size variation within species, a new study finds.

Yale-led study links higher weight in children with structural and functional brain impairments, which could contribute to reduced academic performance. The relationship between weight and brain health in children is less clear than that of obesity in adults, which has consistently been linked to reduced brain health.

A new study by Yale paleontologists charts the radical evolutionary changes to the thigh bones of dinosaurs and birds that allowed them to stand on two feet. Dinosaurs - and birds - wouldn't have been able to stand on their own two feet without some radical changes to their upper thigh bones. Now, a new study by Yale paleontologists charts the evolutionary course of these leggy alterations.

Imagine being able to morph your legs into flippers before you jump in the water. Yale researchers have created a robot that accomplishes this feat through a process they dubbed -adaptive morphogenesis. The project is described in the Oct. 12 edition of Nature and is featured on the issue's cover. The robot, ART (Amphibious Robotic Turtle), takes inspiration from water and land turtles, a group whose fossil record spans over 110 million years.

An extinct reptile's oddly shaped chompers, fingers, and ear bones may tell us quite a bit about the resilience of life on Earth, according to a new study. In fact, paleontologists at Yale, Sam Houston State University, and the University of the Witwatersrand say the 250-million-year-old reptile, known as Palacrodon, fills in an important gap in our understanding of reptile evolution.

In a new analysis, investigators at the Yale Center for Outcomes Research and Evaluation (CORE) and Harvard indicate that in Massachusetts, a state with a high vaccination rate, the most recent wave of SARS-CoV-2 infection was not associated with an increase in mortality. The analysis, published in the journal The Lancet Infectious Diseases , is based on data vaccination and hospital data from Massachusetts, where about 80% of its 6.9 million residents are fully vaccinated.

Most children in the United States diagnosed with obesity do not receive recommended laboratory tests for co-occurring conditions such as diabetes and liver disease, a new Yale study finds. Many also receive potentially unnecessary tests, and both can be harmful to patients, the researchers say. The study was published July 14 in JAMA Network Open.

Illnesses like the common cold and the flu have become endemic in human populations; everyone gets them every now and then, but for most people, they aren-t especially harmful. COVID-19 will eventually transition to endemic status at some point - but when? Possibly within two years, according to a new Yale study published July 5 in the journal PNAS Nexus.

Yale ornithologist Richard Prum has spent years studying the molecules and nanostructures that give many bird species their rich colorful plumage, but nothing prepared him for what he found in hummingbirds. The range of colors in the plumage of hummingbirds exceeds the color diversity of all other bird species in total, Prum and a team of researchers report June 23 in the journal Communications Biology.

Global climate change has already exacerbated the risk of fire and is likely to fuel even more change as accelerating feedback loops create disastrous consequences for both biodiversity and human populations. Yet accurately predicting the risks and impact of bush and wildfire globally is still a work in progress.

While the U.S. spends twice as much on cancer care as the average high-income country, its cancer mortality rates are only slightly better than average, according to a new analysis by researchers at Yale University and Vassar College. The results were published May 27 in JAMA Health Forum.
