Study finds children eat healthier at daycare centers than at home

A recent study by Cincinnati Children's Hospital Medical Center found that preschool-age children consume more calories and fewer fruits, vegetables, and milk outside of child-care centers. The study suggests excess calorie consumption away from the center is significantly associated with being overweight.

Penn team: Sustained remission of multiple myeloma after personalized cellular therapy

A multiple myeloma patient experienced complete remission after receiving a personalized cellular therapy called CTL019, which targets cancerous white blood cells. The treatment was combined with chemotherapy and an autologous stem cell transplant, and the patient remains in remission over 12 months after infusion.

Postoperative delirium results in poor outcomes in older adults

A study published in JAMA Surgery found that postoperative delirium significantly increases adverse outcomes in older adults, including prolonged hospital stays and institutional discharge. Delirium alone exerts the highest risk of adverse outcomes at the population level compared to other major surgical complications.

New research confirms how to take better workday breaks

A new study by Baylor University researchers reveals that taking mid-morning breaks is more beneficial than traditional afternoon breaks for boosting energy, concentration, and motivation. The research also suggests that preferred break activities, such as work-related tasks, are key to restful recovery and improved job satisfaction.

Study points to a possible new pathway toward a vaccine against MRSA

A new study by NYU Langone Health has found that the presence or absence of dueling toxins in Staphylococcus aureus bacteria explains why hospital-acquired MRSA is more deadly than community-acquired forms. The study reveals a key toxin that counteracts another, more deadly toxin, opening up possible new pathways for vaccine development.

Pitt researcher lands the cover of Developmental Cell by uncovering an evolutionary secret

A Pitt researcher used gene regulatory networks to uncover the origins of a recently evolved structure in male fruit flies, finding that it was created by reusing existing networks during development. This discovery sheds light on how complex animal forms arose and challenges the idea that new structures must be encoded by new genes.

Should countries honor their climate debts?

A new study reveals countries with higher per-capita CO2 emissions, like the US and Russia, have accumulated large carbon debts. India is the largest creditor, while Brazil and Indonesia switch from being creditors to debtors due to deforestation and agriculture.

Pitt researchers developing a novel way to identify pathogens

Researchers at the University of Pittsburgh have developed a new method for identifying pathogens using spectroscopy and protein hydrogels. This technique allows for rapid detection and identification of specific pathogens, enabling targeted antibiotic treatment and reducing the risk of misdiagnosis. The broader implications of this wo...

Earthquake baseline set to inform future fracking

A new study published in Marine and Petroleum Geology has established a national baseline for earthquakes caused by human activity in the UK. Since 1999, an average of at least three onshore earthquakes per year with local magnitude greater than or equal to 1.5 have been linked to anthropogenic activities.

Blood and teeth samples accurately predict a criminal's age

Forensic examiners can use blood or teeth samples to estimate an individual's age with great accuracy, helping track down criminals or identify human remains. Researchers at KU Leuven developed a test based on four age-associated DNA methylation markers, achieving margins of error of 3.75 years for blood and 4.86 years for teeth.

Shouldering the burden of evolution

Researchers at UC San Francisco show that early humans' tool use led to changes in their shoulders, which helped the emergence of human-specific traits like high-speed throwing. The study's findings suggest that the common ancestor of modern humans and African apes looked more like a chimp or gorilla.

Arthritis may be a major driver of poverty

Women with arthritis face a 87% higher risk of multidimensional poverty compared to nonarthritic females. Arthritis also affects men, increasing their poverty risk by 22% and 29% for multidimensional poverty, respectively.
