A multi-center randomized controlled trial with critically ill adults aged 50 years and older admitted to intensive care units (ICUs) found that twice-daily slow-tempo music (60 to 80 beats per minute) did not shorten the duration of delirium or coma, or reduce delirium severity, pain or anxiety compared with a silence-track control. While the trial did not mitigate delirium, it showed a trend to fewer days with delirium/coma among patients who received at least seven doses of slow-tempo music. There was also a trend toward fewer days of delirium/coma among patients ...

Sepsis, or infection causing life-threatening organ dysfunction, is a leading cause of death in children worldwide. In efforts to prevent this rare but critical condition, researchers developed and validated AI models that accurately identify children at high risk for sepsis within 48 hours, so that early preemptive care can be provided. These predictive models used routine electronic health record (EHR) data from the first four hours the child spent in the Emergency Department (ED), before organ dysfunction was present. The multi-center study, led by Elizabeth Alpern, MD, MSCE, from Ann & Robert H. Lurie Children’s Hospital of Chicago, is the first to use ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the production of blood stem cells. Human blood stem cells, also known as hematopoietic stem cells, are immature cells that can develop into any type of blood cell, including red blood cells that carry oxygen and various types of white blood cells crucial to the immune system. The embryo-like structures, which the scientists have named ‘hematoids’, are self-organising and start producing blood after around ...

Near-death experiences can have lasting, life-changing effects, and new University of Virginia School of Medicine research sheds light on the types of counseling and support that can best help people cope. The research, from UVA’s Division of Perceptual Studies, is believed to be the first to explore the most common and effective ways to assist people grappling with potentially profound changes to their world view. For most, near-death experiences, or NDEs, have a positive effect; the brush with ...

A new report out today shows that companies taking action for gender equality see lower staff turnover, more women in leadership and better shareholder value. The 10th report in the Gender Equity Insights Series from Bankwest Curtin Economics Centre (BCEC) and the Workplace Gender Equality Agency (WGEA) also warns Australian businesses could fall behind their competitors if they don’t take strong action to address gender balance. The report investigates what drives gender balance. Gender balance means having at least ...

Kiwifruits, rye bread and high mineral-content water could all help alleviate chronic constipation. That’s according to the first ever evidence-based dietary guidelines for adults with chronic constipation, led by researchers at King’s College London. The new guidelines also show that taking psyllium fibre supplements, certain probiotic strains and magnesium oxide supplements can help to improve constipation. In contrast, other widely recommended approaches, including generic “high-fibre diets,” and senna supplements (a type of laxative) were found to lack strong evidence ...

A new open-source tool is reshaping how engineers design multi-material objects. Charles Wade, a PhD student in the Department of Computer Science at the University of Colorado Boulder, has created a design system software package that uses functions and code to map not just shapes but also where different materials belong in a 3D object. The project, called OpenVCAD, was developed in the Matter Assembly Computation Lab led by Assistant Professor Robert MacCurdy of the Paul M. Rady Department of Mechanical Engineering. A new paper, published October 13 in the journal Additive Manufacturing, highlights the design tool and its potential to ...

Cancer is a challenging enough diagnosis, but many patients are dealt a second blow, even as they heal: “chemo brain.” Also called “brain fog,” this mix of cognitive issues — memory problems, struggling to find words, an inability to concentrate — affects up to three-in-four cancer patients, according to multiple studies. For many, the effects last years beyond cancer treatment. A new study offers new models for studying causes of chemo brain and points to the effects of chemotherapy drugs on the brain’s lymphatic system, which ...

A new fossil fuel site approved for development off Western Australia’s coast is estimated to contribute 876 million tonnes of carbon dioxide (CO2) emissions over the course of its lifetime, according to new research led by The Australian National University (ANU) in collaboration with the ARC Centre of Excellence for the Weather of the 21st century.   The level of emissions from the Scarborough project – with liquified natural gas production from the site expected to start in 2026 and continue for at least the next 31 years – will cause, on average, 0.00039 degrees Celsius of additional global warming.    The ...

Heatwaves in the UK have led to unseasonable drying of vegetation bypassing natural ecological processes that limit the spread of wildfires, a new study has found.   In a paper published in the journal Communications Earth & Environment, a team of researchers led by the University of Birmingham have been studying moisture levels in plant life and carbon-rich soil around the UK to understand variations that affect the risk of wildfire. Alongside their three-year sampling period, the first long term survey ...

The infrared spectrometer, named Enfys, will be a part of the suite of remote sensing instruments onboard the ExoMars Rosalind Franklin Rover. The Rosalind Franklin Rover is part of the European Space Agency’s ExoMars programme and Europe’s first Mars rover. Designed to be operated remotely across the planet’s rugged terrain, it will drill up to two metres beneath ...

Most scientific data never fuel the discoveries they should.  For every 100 datasets created, around 80 remain in the lab, 20 are shared but rarely reused, fewer than two meet FAIR standards, and only one typically drives new findings.  The result: delayed cancer treatments, climate models short on evidence, and research that cannot be reproduced.  Frontiers, the open-science publisher, is tackling this problem with the launch of Frontiers FAIR² Data Management, the world’s first all-in-one, ...

Scientists have discovered that mental health patients who have skin conditions may be more at risk of worse outcomes, including suicidality and depression. This work, which may aid in identifying at-risk patients and personalising psychiatric treatment, is presented at the ECNP meeting in Amsterdam. The researchers looked at 481 patients with a first episode of psychosis (which is the first time an individual experiences a psychotic episode, such as loss of contact with reality, hallucinations and delusions).  On testing, 14.5% were found to have dermatological symptoms (24% female, 9.8% male) such as rash, itching, photosensitivity, etc.  All patients were given ...

Researchers have discovered that the ability to have an erection or to orgasm is related to the levels of serotonin in the brain, but this relation only applies to depressed patients taking SSRI antidepressants. At the moment, there is no test for who might experience sexual problems during treatment for depression, but this discovery may help depressed patients to choose antidepressants which allow them to maintain or regain an active sex life when treated with antidepressants. This work is presented at the ECNP conference in Amsterdam. Sexual dysfunction is a common symptom of ...

SAN ANTONIO — Older patients who primarily speak a language other than English may face a greater risk of developing delirium after surgery in U.S. hospitals, according to new research presented at the ANESTHESIOLOGY® 2025 annual meeting. The study also found that a lower socioeconomic status further increased patients’ risk. Postoperative delirium is a change in mental function that can cause confusion in up to 15% of surgical patients. In certain high-risk patients, such as those with hip fractures, the incidence can be even higher. It is a significant complication in older adults. “Our study provides evidence that speaking a first or ...

SAN ANTONIO — Most children — including nearly 80% of infants — go without clear liquids before surgery for at least twice as long as guidelines recommend, according to an analysis of data on more than 70,000 children presented at the ANESTHESIOLOGY® 2025 annual meeting.   Healthy infants and children may safely drink clear liquids, including water, fruit juices without pulp and carbohydrate-containing beverages, until two hours before receiving anesthesia, according to guidelines from the American Society of Anesthesiologists ...
