Nighttime light data shows inequities in restoring power after Hurricane Michael
2024-08-14
Among the many devasting impacts in the aftermath of a hurricane are power outages, which can take days or even weeks to restore. Communities grappling with the loss of electricity may encounter obstacles in accessing vital services, including food, fuel and health care.
In 2018, Hurricane Michael, a Category 5 storm, wreaked havoc in Florida as it made landfall in the United States. It was strongest recorded to hit the Florida Panhandle with winds of nearly 161 miles per hour and storm surge reaching heights ...
Rising mercury pollution in soil could be related to climate change, study says
2024-08-14
In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty’s provisions might not be enough. The study published in ACS’ Environmental Science & Technology estimates that soil stores substantially more mercury than previously thought, and it predicts that increases in plant growth due to climate change may add even more.
Mercury is a persistent environmental pollutant, moving through air, water and soil, and accumulating within plants ...
Exploring the structures of xenon-containing crystallites
2024-08-14
Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it’s difficult to grow sufficiently large crystals that contain noble gases, some of their structures — and therefore functions — remain elusive. Now, researchers have successfully examined tiny crystallites of noble gas compounds. They report structures of multiple xenon compounds in ACS Central ...
Oral cancer screening: Insights into epidemiology, risk factors, and screening programs for improved early detection
2024-08-14
Cancer is a complex disease characterized by uncontrolled cell growth, significantly impacting global health. Head and neck cancers rank as the sixth most prevalent cancers worldwide, with a higher incidence in South-central Asia. Oral squamous cell carcinoma (OSCC) is the predominant malignancy in this category, posing a significant health concern due to its high mortality and often late-stage diagnosis. The significance of early detection and appropriate screening measures cannot be overstated, as they play a pivotal role in improving survival rates and reducing the disease burden.

How air-powered computers can prevent blood clots
2024-08-14
A new, air-powered computer sets off alarms when certain medical devices fail. The invention is a more reliable and lower-cost way to help prevent blood clots and strokes — all without electronic sensors.
Described in a paper in the journal Device, the computer not only runs on air, but also uses air to issue warnings. It immediately blows a whistle when it detects a problem with the lifesaving compression machine it is designed to monitor.
Intermittent pneumatic compression or IPC devices are leg sleeves that fill with air periodically and ...
Fear of appearing prejudiced can inhibit accurate performance feedback to women
2024-08-14
PULLMAN, Wash. – Evaluators who want to avoid appearing prejudiced may overcorrect and give women inflated performance feedback, new research indicates, which is a practice that could ultimately hinder their ability to improve and advance.
A Washington State University-led research team investigated the connection between overly positive performance reviews and “protective paternalism,” the belief that women need to be handled carefully and shielded from harm.
While it may be well-intentioned, ...
Chromatin structure plays a key role in canine social behavior evolution
2024-08-14
A new study on dogs found that chromatin's spatial structure has a significant role in the evolution of social behavior. Chromatin, the compact form of DNA, not only packages genetic material but also plays a crucial role in gene regulation. This study demonstrates that both the linear sequence of DNA and its three-dimensional configuration are linked to friendly behavior shaped by dog domestication, providing new insights into the molecular mechanisms underlying social traits.
Behavioral traits such as sociability are influenced by numerous genes, their interactions, environmental factors, and individual life experiences.
Because ...
Work-related stress may increase the risk of an irregular heart rhythm
2024-08-14
Research Highlights:
Adults in white-collar jobs in Canada with high job strain and for whom significant efforts are met with low rewards (such as low salary or recognition) may face a 97% increased risk for developing the irregular heart rhythm condition known as atrial fibrillation, or AFib or AF, compared to workers not exposed to these work stressors.
Separately, high job strain alone was associated with an 83% higher risk of developing AFib, and effort-reward imbalance alone was associated with a 44% greater risk.
Recognizing and addressing these stressors at work may be an effective strategy ...
Massive biomolecular shifts occur in our 40s and 60s, Stanford Medicine researchers find
2024-08-14
If it’s ever felt like everything in your body is breaking down at once, that might not be your imagination. A new Stanford Medicine study shows that many of our molecules and microorganisms dramatically rise or fall in number during our 40s and 60s.
Researchers assessed many thousands of different molecules in people from age 25 to 75, as well as their microbiomes — the bacteria, viruses and fungi that live inside us and on our skin — and found that the abundance of most molecules ...
Study reveals that memories of the COVID-19 pandemic lockdowns predict declines in psychological well-being of children and adolescents
2024-08-14
The COVID-19 pandemic and the lockdown measures to prevent contagion resulted in extensive disruptions in children’s and adolescents’ everyday lives. A new study in Child Development from the Aarhus University Hospital in Denmark, University of California, Riverside and University of California, Davis in the United States, investigated personal memories (i.e., memories for episodes experienced in one’s own life) about the first lockdown in Denmark in Spring 2020 among children and adolescents and how this may have impacted their psychological well-being over the following year.
For context, in ...

Trojan horse method gives malaria parasites a taste of their own medicine
2024-08-14
More than a quarter of Australians over the age of 50 take cholesterol-lowering drugs to prevent heart disease and strokes, but our bodies also need cholesterol to survive. Now, scientists from The Australian National University (ANU) say its role as a basic building block of life holds the key to treating deadly diseases caused by parasites, including malaria.
The researchers have developed a trojan horse method that tricks malaria parasites into ingesting a fatal dose of drugs by exploiting the parasite’s need for cholesterol to survive. By attaching ...
Singapore scientists discover breakthrough method to activate dormant stem cells in the brain
2024-08-14
Scientists from Duke-NUS Medical School and the Mechanobiology Institute (MBI) at the National University of Singapore (NUS) have discovered a novel pathway to wake up dormant neural stem cells, offering potential new therapies for neurodevelopmental disorders such as autism, learning disabilities, and cerebral palsy.
In the mammalian adult brain, most neural stem cells, which originate from the nervous system and can grow into various types of brain cells, stay dormant until they receive specific signals that activate them. Once woken up, they produce new neurons, aiding in brain repair and growth.
Defects in neural stem cell activation ...
Rare archaeological site reveals ‘surprising’ Neanderthal behaviour at Pyrenees foothills
2024-08-14
An unchartered area in the foothills of the Southern Pyrenees in Spain is providing insights into a poorly known period of Neanderthal history, offering clues that could help archaeologists uncover the mystery of their downfall, according to new research from The Australian National University (ANU).
Abric Pizarro is one of only a few sites worldwide dating from 100,000 to 65,000 years ago during a period called MIS 4. The researchers have gathered hundreds of thousands of artefacts, including stone tools, animal bones and other evidence, providing significant data about the Neanderthal way of life during that time -- largely unknown in human history until now.
The findings ...
How our biases are reflected in how fast we make decisions
2024-08-14
Quick decisions are more likely influenced by initial biases, resulting in faulty conclusions, while decisions that take time are more likely the result in better information, according to new research led by applied mathematicians at the University of Utah.
A team that included Sean Lawley, an associate professor of mathematics, and three former or current Utah graduate students used the power of numbers to test a decision-making model long used in psychology.
They developed a framework to study the decision-making processes in groups of people holding various levels of bias.
“In large populations, what we see is that slow deciders are making more accurate ...

2024-08-14
A new study led by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, found that an episode of shingles is associated with about a 20 percent higher long-term risk of subjective cognitive decline. The study’s findings provide additional support for getting the shingles vaccine to decrease risk of developing shingles, according to the researchers. Their results are published in Alzheimer's Research & Therapy.
"Our findings show long-term implications of shingles and highlight the importance of public health efforts to prevent and promote uptake of the shingles vaccine," said ...
Australians outlive their peers in high income Anglophone countries by 1-4 years
2024-08-14
Australians outlive their peers in 5 high income English speaking countries, including the UK and the US, by between 1 to 4 years, finds an analysis of international longevity data, published in the open access journal BMJ Open.
Most of this advantage accrues between the ages of 45 and 84, with death rates from drug and alcohol misuse, screenable/treatable cancers, and cardiovascular and respiratory diseases all lower, the analysis shows.
While high income countries achieved good life expectancy gains during the 20th century, the trends have been much less favourable in the 21st century, even before the COVID-19 pandemic, note ...
Lack of purpose and personal growth may precede mild cognitive impairment
2024-08-14
Feeling that your life lacks purpose and that there are few opportunities for personal growth in older age may precede the development of mild cognitive impairment (MCI), a frequent precursor of dementia, suggests research published online in the Journal of Neurology Neurosurgery & Psychiatry.
These aspects of psychological wellbeing noticeably decline 2 to 6 years before MCI is diagnosed, even in the absence of evident signs, and irrespective of whether those affected go on to develop dementia, the findings ...
Australia offers lessons for increasing American life expectancy
