Mount Sinai researchers develop novel method to identify patterns among patients with multiple chronic conditions

The study found that high blood pressure, high cholesterol, and diabetes were the most common triplet of chronic conditions, while lung disease and heart attacks were a surprisingly common pair. Patients living in lower-income areas developed a second chronic condition 15 years earlier than their counterparts in higher-income areas.

The first Cr-based nitrides superconductor Pr3Cr10-xN11

Researchers from Chinese Academy of Sciences report discovery of Pr3Cr10-xN11, a chromium-based nitride superconductor with bulk superconductivity at 5.25 K, exhibiting a large upper critical field and strong electronic correlations. The material is the first Cr-based superconductor found in Chromium Nitrides.

Time for a nuclear clock

A four-investigator team led by University of Delaware physicist Marianna Safronova has won a prestigious Synergy Grant to build a nuclear clock, which will be far more sensitive than atomic clocks. The project aims to search for undiscovered physics effects and detect dark matter particles.

Scientists should have sex and gender on the brain

Researchers argue that incorporating sex and gender into scientific studies can improve experiments, reduce bias, and lead to new discoveries. Examples include advancements in climate change research, facial recognition systems, and social robots. The goal is to increase transparency and promote inclusion in research.

Study examines depression in the last year of life

A recent study published in Journal of the American Geriatrics Society found that 59.3% of individuals had depression in the last month before death. Depression symptoms escalated gradually from 4 to 1 months before death, with certain groups experiencing higher rates, such as women and younger adults.

Not so quiet, please

Researchers found that early exposure to sounds can restore molecular, cellular, and functional properties in the auditory cortex of mice with Fragile X Syndrome. This discovery suggests that facilitating exposure to sounds during early development could be a novel approach to treat hypersensitivity associated with FXS.

Shortened sleep may negatively affect women's bone health

A recent study found that postmenopausal women who slept 5 hours or less per night had lower bone mineral density at all four sites assessed. Women reporting 5 hours or less per night were also at higher risk of experiencing low bone mass and osteoporosis, particularly in the hips and spine.

Membrane intercalation enhances photodynamic bacteria inactivation

Researchers have developed a new assembly that enhances photodynamic inactivation of bacteria, achieving significantly improved efficiency against gram-negative E. coli. The assembly combines a photosensitizer and a membrane-intercalating peptide, resulting in nearly 0% survival rate of E. coli upon light irradiation.

Factors during pregnancy may affect early childhood weight

A study of 71,892 children born between 2007-2011 found strong associations between pre-pregnancy obesity in mothers and their children's high body mass index between ages two and six. Modest links were also identified with maternal diabetes and excessive weight gain during pregnancy.

Jaw-some wombats may be great survivors

A recent study reveals that wombat jaws appear to change in relation to their diets, allowing them to adapt to tougher plants due to climate change. The research suggests that individual shapes of wombat skulls are related to an individual's diet and feeding preferences, enabling short-term adaptations.

Web-based calculator predicts risk of death, complications from diabetes and obesity

A new web-based calculator predicts a patient's likelihood of dying from complications or experiencing serious health issues due to type 2 diabetes and obesity, whether they undergo metabolic surgery or continue with standard medical therapy. The Individualized Diabetes Complication Risk Calculator provides a personalized risk score ba...

Perovskite solar cells get an upgrade

Rice University scientists have overcome a major hurdle keeping perovskite-based solar cells from achieving mainstream use by engineering defects and retaining efficiency. They replaced lead with indium, resulting in cells that can be made in open air and last for months.
