DAVIS, CA, December 14, 2023 – A recent study published online in the journal, Nutrients[1], suggests daily tree nut consumption reduces the risk of metabolic syndrome (MetSx) by improving waist circumference, lipid biomarkers, and/or insulin levels, without requiring calorie restriction, in young adults.   In a randomized, parallel arm, dietary intervention study design, researchers at Vanderbilt University Medical Center enrolled 84 men and women, ages 22-36, most of whom were either overweight or obese (BMI 24.5 to 34.9 kg/m2) and had at least one MetSx risk factor ...

Those who binge drink and have a certain genetic makeup are six times more likely to develop alcohol-related cirrhosis, according to new research from UCL, the Royal Free Hospital, the University of Oxford and the University of Cambridge. The study, published in Nature Communications, is the first to assess how an individual’s pattern of drinking, their genetic profile (via a polygenic risk score) and whether or not they have type-2 diabetes affects their risk of developing alcohol-related cirrhosis (ARC). The observation that pattern of drinking is more important than volume, coupled with the increased risk when genetic makeup and type-2 diabetes are also present, ...

PITTSBURGH, Dec. 14, 2023 – Spinal cord stimulation can elicit sensation in the missing foot and alleviate phantom limb pain in people with lower limb amputations, University of Pittsburgh School of Medicine rehabilitation scientists report today. Pressure sensors on the insole of a prosthetic foot triggered electrical pulses that were then delivered to a participants’ spinal cord. Researchers found that this sensory feedback also improved balance and gait stability. The proof-of-concept study was done in collaboration with Carnegie Mellon ...

Cardiovascular diseases are the leading cause of death in the world according to the Global Burden of Disease study, with 18.6 million annual deaths in 2019, of which around 7.9 are attributable to diet. This means that diet plays a major role in the development and progression of these diseases. The modern lifestyle of Western societies has led to specific eating habits such as eating dinner late or skipping breakfast. In addition to light, the daily cycle of food intake (meals, snacks, etc.) alternating with periods of fasting synchronizes the peripheral clocks, or circadian rhythms, of the body’s various organs, thus ...

All dog owners think that their pup is special. Science now has documented that some rare dogs are…even more special! They have a talent for learning hundreds of names of dog toys. Due to the extreme rarity of this phenomenon, until recently, very little was known about these dogs, as most of the studies that documented this ability included only a small sample of one or two dogs. In a new study published in the Journal Scientific Reports, researchers from the Family Dog Project (ELTE Eötvös Loránd  University, Budapest) shed new light on the characteristics of these exceptional dogs. In ...

  Researchers at IRB Barcelona reveal the pivotal role of iron accumulation in the development of fibrotic diseases and propose that iron detection via MRI can serve to diagnose fibrosis. Fibrotic diseases account for 45% of all mortality in developed countries. Published in Nature Metabolism, the study points to new therapeutic opportunities that target iron. Barcelona, 14 December 2023 – Fibrosis is associated with various chronic and life-threatening conditions, including pulmonary fibrosis, liver cirrhosis, kidney disease, and cardiovascular diseases, ...

If you thought blurry eyes were to blame for the “beer goggles” phenomenon, think again. Scientists from the University of Portsmouth have tested the popular theory that people are more likely to find someone attractive while drunk, because their faces appear more symmetrical.  The term “beer goggles” has been used for decades to describe when a person finds themselves sexually attracted to someone while intoxicated, but not sober. One possible explanation for the effect is that alcohol impairs the drinker’s ability to detect facial asymmetry, ...

CORVALLIS, Ore. – Oregon State University scientists have sequenced the chia genome and in doing so provided a blueprint for future research that capitalizes on the nutritional and human health benefits of the plant. In the just-published paper, the researchers identified chia genes associated with improving nutrition and sought after properties for pharmaceuticals that could be used to treat everything from cancer to high blood pressure. The seeds of the chia plant have received widespread attention in recent years because of the nutritional punch they pack. Others have sequenced the chia genome, but this paper provides a more detailed look at the molecular ...

A new paper in Genome Biology and Evolution, published by Oxford University Press, finds that genetic material from Neanderthal ancestors may have contributed to the propensity of some people today to be “early risers,” the sort of people who are more comfortable getting up and going to bed earlier. All anatomically modern humans trace their origin to Africa around 300 thousand years ago, where environmental factors shaped many of their biological features. Approximately seventy-thousand years ago, the ancestors ...

Mice with human immune cells are a new way of testing anti-cancer drugs targeting the immune system in pre-clinical studies. Using their new model, the Kobe University research team successfully tested a new therapeutic approach that blindfolds immune cells to the body’s self-recognition system and so makes them attack tumor cells. Cancer cells display structures on their surface that identify them as part of the self and thus prevent them from being ingested by macrophages, a type of immune cell. Cancer immunotherapy aims at disrupting these recognition systems. Previous studies showed that a substance that blinds macrophages to one of ...

Batteries that exploit quantum phenomena to gain, distribute and store power promise to surpass the abilities and usefulness of conventional chemical batteries in certain low-power applications. For the first time, researchers including those from the University of Tokyo take advantage of an unintuitive quantum process that disregards the conventional notion of causality to improve the performance of so-called quantum batteries, bringing this future technology a little closer to reality. When you hear the word “quantum,” the physics governing the subatomic world, developments in ...

Do you celebrate your birthday in the same month as your mum?  If so, you are not alone. The phenomenon occurs more commonly than expected – a new study of millions of families has revealed.    Siblings also tend to share month of birth with each other, as do children and fathers, the analysis of 12 years’ worth of data shows, whilst parents are also born in the same month as one another more often than would be predicted.    Previous research has found that women’s season of ...

Bat numbers declined as Britain’s trees were felled for shipbuilding in the early colonial period, new research shows. The study, by the University of Exeter and the Bat Conservation Trust (BCT), found Britain’s Western barbastelle bat populations have dropped by 99% over several hundred years. Animals’ DNA can be analysed to discover a “signature” of the past, including periods when populations declined, leading to more inbreeding and less genetic diversity. Scientists used this method to discover the historic decline ...

Due to the merits of low cost, low installation requirements, and high-level safety, aqueous rechargeable batteries (ARBs) offer an ideal option for dealing with future energy-demand pressure. Traditional aqueous batteries are mostly concentrated on mono-valent metal-ion, such as Li+, Na+, and K+. Compared to mono-valent carriers, multivalent cations have the capability to transfer more than one electron, and thereby to potentially provide better energy storage. To date, aqueous multivalent ion batteries based on Zn2+ have received a lot of attention. However, the investigations on aqueous ...

Research led by Professor John McGrath from the University of Queensland found that the concentration of the C4 protein, an important part of the immune system, was not associated with risk of mental disorders.  However, the research also showed that a higher concentration of the C3 protein reduces the risk of schizophrenia in women, and studies based on the genetic correlates of C4 found strong links with several autoimmune disorders.   Professor John McGrath from UQ’s Queensland Brain Institute said his colleagues at Aarhus University in Denmark looked at ...

A clinical trial reported in 2021 and conducted by a team of researchers from Washington University School of Medicine in St. Louis and the International Centre for Diarrhoeal Disease Research in Dhaka, Bangladesh, showed that a newly designed therapeutic food aimed at repairing malnourished children’s underdeveloped gut microbiomes was superior to a widely used standard therapeutic food. Now, another study from the same research team at Washington University School of Medicine has identified key, naturally occurring biochemical components of this new therapeutic food and the important bacterial strains that process these ...

This facility will enable us to care for more children, retain and attract top pediatric physicians ...

The genetic alphabet contains just four letters, referring to the four nucleotides, the biochemical building blocks that comprise all DNA. Scientists have long wondered whether it’s possible to add more letters to this alphabet by creating brand-new nucleotides in the lab, but the utility of this innovation depends on whether or not cells can actually recognize and use artificial nucleotides to make proteins. Now, researchers at Skaggs School of Pharmacy and Pharmaceutical Sciences at the University of California San Diego have ...

A decades-long decline in smoking prevalence in England has nearly ground to a halt since the start of the pandemic, according to a new study led by UCL researchers. The study, funded by Cancer Research UK and published in the journal BMC Medicine, looked at survey responses from 101,960 adults between June 2017 and August 2022. Before the Covid-19 pandemic, from June 2017 to February 2020, smoking prevalence fell by 5.2% a year, but this rate of decline slowed to 0.3% during the pandemic (from April 2020 to August 2022), the study ...

Fossil fuels are at the heart of most human activities, contributing to the increase in greenhouse gas emissions and the ever-rising atmospheric carbon dioxide (CO2) levels. CO2 levels are projected to increase exponentially in future, resulting in severe environmental and ecological impacts. A beacon of hope amidst this chaos are eco-friendly alternatives to fossil fuels. Green energy sources can be developed using advanced biotechnological techniques. One such intervention is the use of biorefineries or microbial cell factories, that convert biomass (organic matter like plants and solid waste) into energy and valuable by-products. The first (1G) ...

The personal yet global struggle with mental health may be more visible now than ever before. Yet many people still find it difficult to access the support they need. In Japan, suicide is sadly the leading cause of death for young people. Researchers, including from the University of Tokyo, have carried out a six-year study to better understand the myriad of factors which can impact adolescent mental health. After surveying 2,344 adolescents and their caregivers, and using computer-based deep learning to process the results, they were able to identify five categories which the young people could be grouped into. Nearly 40% of those involved were ...

Improving the mental health and wellness of Black Americans requires acknowledging and confronting systemic racism underlying the US political, social, and healthcare systems that create and maintain racial inequality in every aspect of life for Black people in the USA.  The new Series of three papers on Black mental health in the USA, plus an essay from Black Americans with lived experience, published inThe Lancet Psychiatry journal, outlines the overwhelming evidence for the role racism plays in producing, maintaining, and amplifying mental health disparities for Black Americans. Against this background, the authors call for a comprehensive analysis of the conditions and systems in ...

UK organisations responsible for protecting the public from prescription-only drug adverts are putting patients at risk from the harms of weight loss drugs by not enforcing the law, reveals an investigation published by The BMJ today. Legal responsibility for regulating adverts for medicines in the UK rests with the Medicines and Healthcare products Regulatory Agency (MHRA) on behalf of health ministers. But there is also a system of self-regulation with a number of bodies operating their own codes of practice, including the Advertising Standards Authority (ASA). But The BMJ has found that the MHRA has not issued a single sanction for prescription drugs in the last ...

Researchers at Sinai Health have unearthed vital information about the relationship between insulin levels after eating and long-term heart and metabolic health. The research upends the notion that insulin surge following food intake is a bad thing. On the contrary – it could be an indicator of good health to come. Led by Dr. Ravi Retnakaran, Clinician-Scientist at the Lunenfeld-Tanenbaum Research Institute, part of Sinai Health, the study set out to explore how insulin levels after meals impact cardiometabolic health. While past ...

Body dissatisfaction at age 11 is linked to increased risk of depression by age 14, finds a new longitudinal study led by UCL researchers. The findings, published in The Lancet Psychiatry, show that body image concerns explain a large proportion of an association between body mass index (BMI) and depression in children, particularly in girls. The study, supported by Wellcome, involved 13,135 participants of the Millennium Cohort Study, a UCL-led nationally representative birth cohort study of people born between 2000 and 2002. The researchers found that high BMI at age seven was linked with increased depressive symptoms (which can include low mood, loss of pleasure ...
