One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes over 85% of the matter in the Universe), but we have never seen it directly and still do not know what it is. A new study published in JCAP has examined traces of antimatter in the cosmos that could reveal a new class of never-before-observed particles, called WIMP (Weakly Interacting Massive Particles), which could make up dark matter. The study suggests that some recent observations ...

Nearly three out of four kids in Chicago had no swimming lessons in summer of 2022, with significant racial and ethnic differences, according to a parent survey from Ann & Robert H. Lurie Children’s Hospital of Chicago published in Pediatrics. Black and Hispanic/Latine kids were disproportionately affected (85 percent and 82 percent, respectively), compared to white kids (64 percent). The most common reasons for not getting swimming lessons also differed among racial and ethnic groups. Parents of White kids reported they ...

□ Professor Jongmin Choi’s team from the Department of Energy Science and Engineering at DGIST (President Kunwoo Lee) conducted joint research with Materials Engineering and Convergence Technology Professor Tae Kyung Lee from Gyeongsang National University and Applied Chemistry Professor Younghoon Kim from Kookmin University. The researchers developed a new method to improve both the performance and the stability of solar cells using “perovskite quantum dots.” They developed longer-lasting solar cells by addressing the issue of distortions on the surface of quantum dots, which deteriorate the ...

Rehearsing alternative outcomes of discarding through imagery rescripting shows promise as a treatment strategy for people who hoard, a study by UNSW psychology researchers has shown. Hoarding disorder is a highly debilitating condition that worsens with age. People who hoard form intense emotional attachments to objects, accumulate excessive clutter, and have difficulty discarding possessions. Many avoid treatment. People who hoard also experience more frequent, intrusive and distressing mental images in their daily lives, says Mr Isaac Sabel from the Grisham Research Lab, an experimental clinical psychology research group at UNSW Sydney. “Negative ...

The dental health benefits of adding fluoride to drinking water may be smaller now than before fluoride toothpaste was widely available, an updated Cochrane review has found. The team of researchers from the Universities of Manchester, Dundee and Aberdeen reviewed the evidence from 157 studies which compared communities that had fluoride added to their water supplies with communities that had no additional fluoride in their water. They found that the benefit of fluoridation has declined since the 1970s, when fluoride toothpaste became more widely available. The contemporary studies were conducted in high-income countries. The impact of community water fluoridation ...

Toddlers in the UK obtain nearly half (47%) of their calories from ultra-processed foods (UPFs), and this rises to 59% by the age of seven, according to a new study led by UCL researchers. The study, published in the European Journal of Nutrition, looked at data from 2,591 children born in the UK in 2007 and 2008 whose parents recorded what their children ate and drank over three days. The most common UPFs consumed by the toddlers – who were 21 months when their parents recorded their diets – were flavoured ...

DETROIT — A new grant will help Wayne State University researchers explore the links between bacterial infections, the environmental factors that increase their susceptibility and the risk of preterm birth. The five-year, $2,858,821 grant from the National Institute of Environmental Health Sciences of the National Institutes of Health, “PFAS increases susceptibility to infection-mediated preterm birth,” will be led by Michael Petriello, Ph.D., assistant professor in Wayne State’s Institute of Environmental Health Sciences and Pharmacology in the School of Medicine. Petriello hopes that the team’s studies will identify critical pathways responsible ...

Highlights: Antimicrobial resistance is a growing threat. Bacteria exchange AMR genes in the gut via circular genetic material called plasmids. In lab experiments, bacteria transferred plasmids with AMR genes in the presence of zinc at reduced or nonexistent rates. Stopping the transfer without killing microbes may help reduce AMR without disrupting the gut microbiome. Washington, D.C.—Genes responsible for antimicrobial resistance (AMR) can spread from microbe to microbe through circular genetic material called plasmids, and ...

MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request. Images and Podcast EAST LANSING, Mich. – In recent years, some states have prioritized purging their voter rolls of those who have passed away or moved out of state. During election season, there is often increased discussion about the necessity and impact of these actions. Voter purging can be an important step for creating election integrity, but others have raised concerns about how the process is conducted and who it targets. So, are there negative effects of voter purging? Researchers from Michigan State University wanted to find out — especially ...

In this study, the Cancer Research UK-funded scientists will establish the targets for the vaccine. They will find out which proteins on the surface of early-stage ovarian cancer cells are most strongly recognised by the immune system and how effectively the vaccine kills mini-models of ovarian cancer called organoids. If this research is successful, work will then begin on clinical trials of the vaccine. The hope is that in the future, women could be offered this vaccine to prevent ovarian cancer in the first place. There are around 7,500 new ovarian ...

COLUMBUS, Ohio – Researchers have developed a way to make one type of plastic material more durable and less likely to shed dangerous microplastics. The study identified a secure way to attach chemical additives to polyvinyl chloride (PVC).  Found in everything from toys, construction supplies and medical packaging, PVC plastics currently rank third among the most used plastics worldwide. Despite its widespread use, pure PVC is brittle and sensitive to heat, and manufacturers can only utilize it after stabilizing its properties with other chemicals.  However, these additives, or plasticizers, ...

The nearly $600,000 grant by the NIH’s National Institute of Dental and Craniofacial Research will address this critical pain issue that significantly impairs quality of life. Many head and neck carcinoma patients require opiate pain management, but tolerance develops quickly, requiring new pain ...

Public health degree programs provide key competencies demanded by employers, but graduate employability could be improved by using more real-time data from employer job postings, according to a new study at Columbia University Mailman School of Public Health. This could help public health schools and programs ensure that graduates obtain specific technical skills listed in job postings, meet current employer needs, and prepare graduates for the demands of today’s labor market. The findings are published in the American Journal of Public Health. The competencies required for the ...

Since the 2020 murder by Minneapolis police of George Floyd brought nationwide calls for change amid concerns that prevailing practices were not grounded in evidence and created harm, policing has been in turmoil. Implementation science (IS) involves integrating effective and evidence-based innovations into routine practice in fields like health care. Yet despite its potential, IS—and specifically, evidence-based policing (EBP)—remain vastly understudied and unused in police settings. In a new article, researchers provide an orientation to these issues ...

Looking deep into the early universe with NASA’s James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas outshining its stars. Found approximately one billion years after the big bang, galaxy GS-NDG-9422 (9422) may be a missing-link phase of galactic evolution between the universe’s first stars and familiar, well-established galaxies. “My first thought in looking at the galaxy’s spectrum was, ‘that’s weird,’ which is ...

Moscow, Idaho, October 3, 2024:   New research showing the association between greater bean and pulse consumption and improved shortfall nutrient intakes and a higher diet quality in American adults will be presented during the Academy of Nutrition and Dietetics (the Academy) Food & Nutrition Conference & Expo (FNCE) 2024 in Minneapolis, MN. The poster session is scheduled for Tuesday, October 8, 2024, from 10:45 – 11:45 AM CT at the Minneapolis Convention Center.   Researchers assessed the effect of increased bean and pulse consumption, in the typical US dietary pattern, on shortfall ...

Auditory hallucinations are likely the result of abnormalities in two brain processes: a “broken” corollary discharge that fails to suppress self-generated sounds, and a “noisy” efference copy that makes the brain hear these sounds more intensely than it should. That is the conclusion of a new study published October 3rd in the open-access journal PLOS Biology by Xing Tian, of New York University Shanghai, China, and colleagues. Patients with certain mental disorders, including schizophrenia, often hear voices in the absence of sound. Patients may fail to distinguish between their ...

When humans began farming crops thousands of years ago, agriculture had already been around for millions of years. In fact, several animal lineages have been growing their own food since long before humans evolved as a species. According to a new study, colonies of ants began farming fungi when an asteroid struck Earth 66 million years ago. This impact caused a global mass extinction but also created ideal conditions for fungi to thrive. Innovative ants began cultivating the fungi, creating an evolutionary partnership that became even more tightly intertwined 27 million years ago and continues to this day. In a paper published today, Oct. 3, in the journal Science, scientists at the Smithsonian’s ...

The extinction of hundreds of bird species caused by humans over the last 130,000 years has has led to substantial reductions in avian functional diversity – a measure of the range of different roles and functions that birds undertake within the environment –  and resulted in the loss of approximately 3 billion years of unique evolutionary history, according to a new study published today in Science.  Whilst humans have been driving a global erosion of species richness for millennia, the consequences of past extinctions for other dimensions of biodiversity are poorly known. ...

Researchers from DZNE and Otto von Guericke University Magdeburg have identified individuals with increased risk for dementia using mobility data, recorded during a smartphone-based wayfinding task on the university campus. The findings, reported in the journal PLOS Digital Health, show the potential of smartphone data, collected in conditions close to everyday life, for the early detection and monitoring of Alzheimer’s disease. The study included 72 adults; about a third of them with subjective cognitive decline (SCD), a condition that is a known risk factor for dementia. Alzheimer’s disease usually develops unnoticed over years and eventually ...
