From One Cell review: Embryology and the future of medicine

Posted by in categories: biotech/medical, health

From marigolds to human babies, most complex organisms start as a single-celled embryo. In his new book, Ben Stanger explores what our humble origins could teach us about health and disease.

Consumer Health: Are you considering contact lenses?

Posted by in categories: biotech/medical, health

Contact Lens Health Week will be observed Aug. 21–25, which makes this a good time to learn more about contact lenses and whether they might be right for you.

Eyeglasses can be fun and fashionable. And they’re a safe and effective way to provide vision correction for most people. Contact lenses also can provide a safe and effective way to correct your vision, and more than 45 million people in the U.S. wear contact lenses, according to the Centers for Disease Control and Prevention.

If you’re considering switching to contact lenses, here are some things you should consider.

Postdoctoral Fellow in Microbial Genomics, Bacterial Pathogenesis and Antimicrobial Resistance Unit

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

The National Institute of Allergy and Infectious Diseases (NIAID), one of the largest institutes in the National Institutes of Health (NIH), part of the Department of Health and Human Services (HHS), conducts and supports basic and applied research to better understand, treat, and ultimately prevent infectious, immunologic, and allergic diseases. The Bacterial Pathogenesis and Antimicrobial Resistance Unit (chief John Dekker) in the Laboratory of Clinical Immunology and Microbiology in the Division of Intramural Research (DIR) within NIAID seeks candidates for a postdoctoral fellowship position in microbial genomics.

This position will offer a unique opportunity to work at the intersection of pathogen genomics, systems biology, and clinical infectious diseases. The lab uses a variety of genomics, transcriptomics, metabolomics, imaging, and molecular approaches to study bacterial pathogens and antimicrobial resistance, with a focus on intra-host evolution in the context of infection. Access to state-of-the-art short-and long-read sequencing, metabolomics, optical, and computational resources is available. See more information about the Bacterial Pathogenesis and Antimicrobial Resistance Unit under chief John P. Dekker and an example of their recent work.

Neuropsychiatric behavioral symptoms are associated with divorce, study finds

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

Older adults with more severe behavioral symptoms, including agitation, aggression, and disinhibition, are more likely to become divorced than those with less severe symptoms. However, increasing stages of dementia are associated with a low likelihood of divorce. These are some of the conclusions of a new study published August 16 in the open-access journal PLOS ONE by Joan Monin of the Yale School of Public Health and colleagues.

In recent years, divorce has been on the rise among older adults. Moreover, can be difficult for married couples for many reasons, including the introduction of caregiving burden, loss of intimacy, and financial strain.

In a new study, researchers analyzed data from 37 NIA/NIH Alzheimer’s Disease Research Centers (ADRCs) across the US. The final study included 263 married or living-as– who were divorced or separated during their follow up period at an ADRC, as well as 1,238 age-matched controls.

Following chronic fatigue mechanisms to the source: WASF3 and mitochondrial respiration

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

Researchers at the National Heart, Lung, and Blood Institute at NIH, Bethesda, have discovered a potential breakthrough for people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), marked by extreme exhaustion, post-exertional malaise and cognitive issues.

In a paper, “WASF3 disrupts and may mediate exercise intolerance in /,” published in PNAS, the team details the influence of increased WASF3 proteins on the assembly of mitochondrial proteins, hampering energy production.

The study focused on a woman (S1) who experienced severe long-term fatigue. Measuring her muscles for phosphocreatine regeneration after exercise revealed a significant delay in mitochondrial ATP synthesis capacity. This discovery was followed up with a cell assay which found increased phospho-activation of an enzyme in a signaling pathway (MPAK).

Researchers study the intricate processes underpinning gene expression

Posted by in categories: biotech/medical, health, information science, robotics/AI

A new study led by University of Maryland physicists sheds light on the cellular processes that regulate genes. Published in the journal Science Advances, the paper explains how the dynamics of a polymer called chromatin—the structure into which DNA is packaged—regulate gene expression.

Through the use of machine learning and statistical algorithms, a research team led by Physics Professor Arpita Upadhyaya and National Institutes of Health Senior Investigator Gordon Hager discovered that can switch between a lower and higher mobility state within seconds. The team found that the extent to which chromatin moves inside cells is an overlooked but important process, with the lower mobility state being linked to gene expression.

Notably, (TFs)—proteins that bind specific DNA sequences within the chromatin polymer and turn on or off—exhibit the same mobility as that of the piece of chromatin they are bound to. In their study, the researchers analyzed a group of TFs called , which are targeted by drugs that treat a variety of diseases and conditions.

Google’s Apparently Building an AI That Tells You How to Live Your Life

Posted by in categories: biotech/medical, finance, health, law, robotics/AI

Google DeepMind researchers have finally found a way to make life coaching even worse: infuse it with generative AI.

According to internal documents obtained by The New York Times reports, Google and the Google-owned DeepMind AI lab are working with “generative AI to perform at least 21 different types of personal and professional tasks.” And among those tasks, apparently, is an effort to use generative AI to build a “life advice” tool. You know, because an inhuman AI model knows everything there is to know about navigating the complexities of mortal human existence.

As the NYT points out, the news of the effort notably comes months after AI safety experts at Google said, back in just December, that users of AI systems could suffer “diminished health and well-being” and a “loss of agency” as the result of taking AI-spun life advice. The Google chatbot Bard, meanwhile, is barred from providing legal, financial, or medical advice to its users.

Genetic determinants of retinol circulation and their impact on health

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

In a recent pre-print study posted to the medRxiv* server, researchers conducted a comprehensive genome-wide association study (GWAS) to elucidate the genetic architecture of circulating retinol, identify its potential causal relationships with various clinical phenotypes, and evaluate its therapeutic or nutritional implications.

A simple mouth rinse could spot early heart disease risk

Posted by in categories: biotech/medical, health

What if we could identify the earliest warning signs of cardiovascular disease from a simple saliva sample? Scientists think they have found a way to do so. Gum inflammation leads to periodontitis, which is linked with cardiovascular disease.

The team used a simple oral rinse to see if levels of —an indicator of —in the saliva of healthy adults could be linked to warning signs for cardiovascular disease. they found that high levels correlated with compromised flow-mediated dilation, an early indicator of poor arterial health.

“Even in young healthy adults, low levels of oral inflammatory load may have an impact on cardiovascular health—one of the leading causes of death in North America,” said Dr. Trevor King of Mount Royal University, corresponding author of the study published in Frontiers in Oral Health.

Google reportedly building A.I. that offers life advice

Posted by in categories: health, robotics/AI


One of Google’s AI units is using generative AI to develop at least 21 different tools for life advice, planning and tutoring, The New York Times reported Wednesday.

Google’s DeepMind has become the “nimble, fast-paced” standard-bearer for the company’s AI efforts, as CNBC previously reported, and is behind the development of the tools, the Times reported.
