Alzheimer’s: Abdominal fat linked to poor brain health, cognition

Posted by in categories: biotech/medical, health, neuroscience

A new study suggests abdominal fat could impact brain health and cognition among people with a high risk of developing Alzheimer’s disease. Researchers found that middle-aged males at risk for Alzheimer’s who had higher amounts of pancreatic fat had lower cognition and brain volumes.

Ink Alert: Discrepancies Found in Tattoo Ink Composition

Posted by in categories: biotech/medical, chemistry, government, health

Dr. John Swierk: “This is also the first study to explicitly look at inks sold in the United States and is probably the most comprehensive because it looks at the pigments, which nominally stay in the skin, and the carrier package, which is what the pigment is suspended in.”


Do the ingredients in tattoo inks match the labels on their respective bottles? This is what a recent study published in Analytical Chemistry hopes to address as a team of researchers from Binghamton University investigated the accuracy of ink ingredients and what’s labeled on their containers. This study holds the potential to help scientists, artists, and their customers better understand the health risks, to include allergic reactions and other risks, of using the wrong ink ingredients for tattoos.

For the study, the researchers examined ingredients from 54 inks emanating from nine common brands within the United States with the goal of ascertaining their exact chemical compositions compared to what was labeled on their respective bottles. In the end, the researchers identified that 45 of the 54 inks possessed a myriad of pigments and/or additives that were not properly labeled on the bottles that could pose health risks to customers receiving ink tattoos, including allergic skin reactions and other long-term health risks, including non-skin-related risks, such as cancer. Despite the alarming findings, the researchers could not ascertain which unlisted ingredients were intentionally or accidentally added to the inks.

Graphene research: Numerous products, no acute dangers

Posted by in categories: health, neuroscience

Think big. Despite its research topic, this could well be the motto of the Graphene Flagship, which was launched in 2013: With an overall budget of one billion Euros, it was Europe’s largest research initiative to date, alongside the Human Brain Flagship, which was launched at the same time.

The same applies to the review article on the effects of graphene and related materials on health and the environment, which Empa researchers Peter Wick and Tina Bürki just published together with 30 international colleagues in the journal ACS Nano; they summarize the findings on the health and ecological risks of graphene materials, the reference list includes almost 500 original publications.

A wealth of knowledge—which also gives the all-clear. “We have investigated the potential acute effects of various graphene and graphene-like materials on the lungs, in the and in the placenta—and no serious acute cell-damaging effects were observed in any of the studies,” says Wick, summarizing the results.

The Last Piece of Our Genome: Sequencing the Y Chromosome

Posted by in categories: biotech/medical, genetics, health

Groundbreaking research led by a global group of over 100 researchers will enable a more in-depth exploration of human genetic variation as fully sequencing the Y chromosome, a feat that has challenged scientists for years, has been accomplished for the first time. In this interview, we speak to Dylan Taylor about this impactful research and how it may shape our understanding of human genetics.

Please could you introduce yourself and your current research activities?

I am Dylan Taylor, a Ph.D. candidate and NIH F31 fellow in the Department of Biology at Johns Hopkins University. My work with the T2T consortium focuses on exploring how a complete reference genome can improve our ability to study human genetic variation and how it impacts human traits and health.

Measles is a ‘heat-seeking missile’ experts warn as Florida outbreak grows

Posted by in categories: biotech/medical, health

The Florida measles outbreak is expanding. On Friday, health officials in Broward County confirmed a seventh case of the virus, a child under age 5.

The patient is the youngest so far to be infected in the outbreak, and the first to be identified outside of Manatee Bay Elementary School in Weston, near Fort Lauderdale.

It’s unknown what connection the youngest measles case has to the school, but the spread beyond school-age kids was expected.

Next Generation Neural Interfaces: Research on Emerging Technologies at Imperial College London

Posted by in categories: biotech/medical, health, neuroscience

The era of bioelectronic healthcare is dawning upon us. As electronic systems shrink in size and improve in functionality, we see more and more emerging devices that can track vital signs, such as heart rate and blood pressure, realising the grand vision of highly connected sensor nodes monitoring patients’ health beyond the hospital doors. The real revolution in digital healthcare, however, lies in bringing not only the diagnostics but also the therapy to the patient which requires interfacing the world of electronics with biology.

Interfacing the nervous system provides an immense opportunity to observe (through recording) and modify (through stimulation) the functional state of the biological system to fundamentally understand various diseases and health conditions, and to ultimately develop suitable therapies through closed-loop systems [1]. Consequently, a host of neural interface modalities, with varying levels of invasiveness, have been developed over the past decades. Among all, interfacing at the individual neuron level allows the highest level of information transfer from the brain.

Despite the success of devices such as Cochlear Implants, interfacing at the individual neuron level is still severely limited due to challenges such as selectivity (for stimulation) and thermal-limitations imposed on data transmission to prevent neural tissue damage. The latter is a major bottleneck in improving information transfer rate of neural recording systems as they scale up. Hence, there is currently a tremendous drive to develop new enabling technologies for neuroscience to provide insightful views on how motor or sensory information is represented and transformed by the brain, as well as revealing how this complex system is affected by neurological injuries and disease.

Researchers create more realistic synthetic human mini hearts

Posted by in categories: biotech/medical, engineering, health

Thanks to advancements in the development of patented synthetic human-like hearts first created at Michigan State, researchers can study human heart development and congenital heart disease on highly accurate models. This is facilitating the development of new therapies and pharmaceutical drugs to treat a variety of heart-related diseases just in time for the observance of American Heart Month in February.

Similar in size and development to fetal human hearts, these mini heart organoids are becoming increasingly complex and realistic. The MSU research team that created the mini hearts first published their findings in 2020. They have quickly become a world leader in this field and their latest advancements have been published in Nature Communications and Stem Cell Reports.

Aitor Aguirre, associate professor of biomedical engineering and chief of the division of developmental and in MSU’s Institute for Quantitative Health Science and Engineering, explained that the introduction of realistic models is essential to the discovery of effective and clinically translatable solutions to . An estimated 21 million annual deaths are related to this condition, including disorders of the heart and blood vessels. And that number is growing.

Vision impairment in older adults tied to symptoms of depression, anxiety and social isolation: JAMA

Posted by in categories: biotech/medical, health, neuroscience

USA: A cross-sectional study comprising 2,822 US adults revealed that worse examination-based and self-reported vision impairment is associated with anxiety and depressive symptoms, and worse examination-based vision impairment is linked with severe social isolation.

These findings, published in JAMA Ophthalmology, provide evidence to support prioritizing research aimed at enhancing the health and inclusion of people with vision impairment.

Vision impairment and psychosocial function, including symptoms of anxiety, depression and social isolation, are a major cause of morbidity in the US. However, there is a lack of nationally representative studies evaluating associations between subjective and objective vision impairment with psychosocial function following the COVID-19 pandemic.
