Statin therapy not associated with cognitive decline, dementia in older adults, study says
The use of statin therapy in adults 65 years old or older is not associated with incident dementia, mild cognitive impairment (MCI) or decline in individual cognition domains, according to a study published in the Journal of the American College of Cardiology (JACC).

Study shows registry data could support clinical trials
Data captured in NCDR registries is similar in quality, depth and granularity when compared to data captured through clinical trials, according to research in JACC: Cardiovascular Interventions that compared data from the DAPT Study to NCDR CathPCI Registry data. This is good news for streamlining data collection and supports recent efforts to standardize data elements and definitions used in clinical trials and registries.

Childhood BMI may influence poorer health outcomes in adulthood
A high body mass index (BMI) during adolescence is a significant risk factor for Type 2 diabetes, early heart attack and overall poorer health for young adults, regardless of BMI in adulthood, according to a research letter published today in the Journal of the American College of Cardiology.

Researchers discover how the intestinal epithelium folds and moves by measuring forces
An international team led by Xavier Trepat at IBEC, with support from "La Caixa Foundation, measures the cellular forces in mini-intestines grown in the laboratory, deciphering how the inner wall of this vital organ folds and moves. The study, published in Nature Cell Biology, opens the doors to a better understanding of the bases of diseases such as celiac disease or cancer, and to the ability to find solutions for gut diseases through the development of new therapies.

Japanese, Italian, US physicists reveal new measurements of high-energy cosmic rays
New findings published this week in Physical Review Letters suggest that cosmic ray nuclei of hydrogen, carbon and oxygen travel through the galaxy toward Earth in a similar way, but, surprisingly, that iron arrives at Earth differently.

New research unlocks the mystery of New England's beaches
Until now, the factors governing which beaches slope gradually to the sea and which ones end abruptly in a steep drop-off have been largely unknown. However, new research from the University of Massachusetts Amherst reveals, with unprecedented detail, how the grain size of beach sand relates to the slope of the beach itself. These new findings are critical to understanding how New England's beaches will respond to both rising sea levels and increased storm activity.

Physicists made photons be friends with magnons
A team of scientists from NUST MISIS and MIPT have developed and tested a new platform for realization of the ultra-strong photon-to-magnon coupling. The proposed system is on-chip and is based on thin-film hetero-structures with superconducting, ferromagnetic and insulating layers. This discovery solves a problem that has been on the agenda of research teams from different countries for the last 10 years, and opens new opportunities in implementing quantum technologies.

Third of Americans use gray market caregivers to aid the elderly and those with dementia
The rapid aging of the US population is expected to increase the demand for long-term care and supports to help with the activities of daily living. A new study finds that nearly a third of Americans who arranged for paid care for an older person or someone with dementia employed workers who were not hired through a regulated agency.

Antibody disease enhancement of COVID-19 does not appear to occur in animal models
In a study published in the journal Cell, Duke investigators demonstrated in mice and monkeys that human antibodies lacked the ability to make SARS-CoV-2 infection worse and, instead, exerted their defensive powers against the infection. The findings help reinforce evidence that antibodies are safe when given as treatments or induced by COVID-19 vaccines.

Computers help researchers find materials to turn solar power into hydrogen
A Penn State-led team of researchers reports that it has taken a step toward overcoming the challenge of inexpensive hydrogen production by using supercomputers to find materials that could help accelerate hydrogen separation when water is exposed to light, a process called photocatalysis.

Gene profile in blood predicts risk of poor outcomes, death for patients with COVID-19
A blood gene profile associated with a high risk of dying from a severe lung disease can also predict poor outcomes in patients with COVID-19, a multicenter retrospective study led by the University of South Florida Health (USF Health) demonstrated. The risk profile based on 50 genes could help customize how COVID-19 is treated, improve allocation of limited health care resources such as intensive care beds and ventilators, and potentially save lives.

Blaming the pandemic for stress leaves couples happier
When the COVID-19 pandemic hit during the winter of 2020, locking down entire countries and leaving people isolated in their homes without outside contact for weeks at a time, many relationship experts wondered what that kind of stress would do to romantic couples. What they found was that when couples blamed the pandemic for their stress, they were happier in their relationships.

Better reporting of studies on artificial intelligence: CONSORT-AI and beyond
An increasing number of studies on artificial intelligence (AI) are published in the dental and oral sciences but aspects of these studies suffer from a range of limitations. Standards towards reporting, like the recently published CONSORT-AI extension, can help to improve studies in this emerging field. Watch authors discuss the Journal of Dental Research (JDR) article 'Better Reporting of Studies on Artificial Intelligence: CONSORT-AI and Beyond.'

New model simulates the tsunamis caused by iceberg calving
A team of scientists has developed a new model for simulating both iceberg calving and the tsunamis that are triggered as a result. Their method can help improve hazard assessment in coastal areas and refine the empirical calving models used to evaluate rising sea levels.
