Effect of electric fans on body core temperature in older adults exposed to extreme indoor heat

JAMA

2024-10-17

(Press-News.org) About The Study: Electric fan use did not lower peak core temperature in older adults exposed to extreme indoor heat. Reductions in end-exposure core temperature and heart rate were observed, but they were small and of questionable clinical importance. Neither exceeded previous suggestions for clinical significance. Consistent with recent modeling, these data do not support fans as an efficacious standalone cooling intervention for older adults in hot indoor environments (>33-35 °C).

Buprenorphine/naloxone vs methadone for the treatment of opioid use disorder

2024-10-17

About The Study: Individuals receiving methadone had a lower risk of treatment discontinuation compared with those who received buprenorphine/naloxone. The risk of mortality while receiving treatment was similar between medications. Corresponding Author: To contact the corresponding author, Bohdan Nosyk, PhD, email bnosyk@sfu.ca.

Astrobiology: Potential microbial habitats in Martian ice

2024-10-17

Dusty ice exposed at the surface of Mars could provide the conditions necessary for the presence of photosynthetic life, according to a modelling study. The findings, published in Communications Earth & Environment, suggest that ice deposits located in the planet’s mid-latitudes should be a key location in any search for life on Mars. High levels of harmful ultraviolet radiation from the Sun make current life on the surface of Mars almost certainly impossible. However, a sufficiently thick layer of ice can absorb this radiation and could protect cells living below its surface. Any life in these conditions ...

IChF tribute to the chemical imagination: the Dream Chemistry Award

2024-10-17

The Dream Chemistry Award (DCA) is a one-of-a-kind competition dedicated to recognizing young scientists who dream of tackling fundamental problems in chemistry and related disciplines with visionary ideas. Established in 2013 by the Institute of Physical Chemistry of the Polish Academy of Sciences (IChF), the award aims to support emerging talents in realizing their scientific dreams. Since 2017, it has been organized jointly with the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (IOCB Prague), with the finals alternating between Prague and Warsaw. The Dream Chemistry Award empowers those pursuing ...

New tool helps analyze pilot performance and mental workload in augmented reality

2024-10-17

In the high-stakes world of aviation, a pilot's ability to perform under stress can mean the difference between a safe flight and disaster. Comprehensive and precise training is crucial to equip pilots with the skills needed to handle these challenging situations. Pilot trainers rely on augmented reality (AR) systems for teaching, by guiding pilots through various scenarios so they learn appropriate actions. But those systems work best when they are tailored to the mental states of the individual subject. Enter HuBar, a novel visual analytics tool designed to summarize and compare task performance ...

Researchers advance ideas on abiotic organic synthesis

2024-10-17

Recently, a Chinese research team reported the discovery of abiotic organic compounds in the oceanic crust of the Southwest Indian Ridge and proposed a molecular mechanism for organic condensation. This breakthrough followed the team’s discovery of nanoscale abiotic organic matter in mantle rocks from the Yap Trench in 2021. It represents a significant advance in research on deep-sea carbon cycling and the origin of life, shedding light on key pathways for abiotic organic synthesis in nature. The scientists published their findings in the Proceedings ...

Visible light energy yields two-for-one deal when added to CO2 recycling process

2024-10-17

CHAMPAIGN, Ill. — By combining visible light and electrochemistry, researchers have enhanced the conversion of carbon dioxide into valuable products and stumbled upon a surprising discovery. The team found that visible light significantly improved an important chemical attribute called selectivity, opening new avenues not only for CO2 conversion but also for many other chemical reactions used in catalysis research and chemical manufacturing. One way that chemists recycle CO2 into valuable products is through a process called electrochemical reduction, where a stream of CO2 gas moves through an electrolysis cell that breaks the CO2 and water ...

Search continues for a treatment that reduces long COVID symptoms

2024-10-17

The first randomized, placebo-controlled clinical trial evaluating the impact of therapeutic monoclonal antibodies on the risk of developing long COVID was led by researchers at Weill Cornell Medicine. The study, published Sept. 1 in eClinicalMedicine, details an international, multicenter phase 2/3 clinical trial that found a combination of amubarvimab and romlusevimab did not reduce the occurrence of long COVID symptoms. Lasting weeks or even months after SARS-CoV-2 infection, long COVID is characterized by a variety of symptoms that affect each person differently. These include extreme fatigue, difficulty concentrating, ...

License to chill: Bond shows ‘regressive nostalgia’ can freeze a brand's future

2024-10-17

Super-spy James Bond is a prime example of ‘regressive nostalgia’ highlighting how certain consumer groups cling to idealised past versions of brands and resist attempts to move with the times, a new study reveals. Researchers examined the James Bond movie franchise - a cultural icon for over 70 years - and discovered that some ‘super-consumers’ react negatively to modern portrayals of the fictional British secret agent that reflect contemporary societal values. Whilst loyal to the brand, these consumers prefer traditional, more exclusionary, versions of Bond which most closely follow author Ian Fleming’s original 1950s and 1960s vision – ...
