Discovery of ‘molecular machine’ brings new immune therapies a step closer

Posted by in categories: biotech/medical, nanotechnology

Guanylate binding proteins (GBP) were discovered by YSM’s John MacMicking, PhD, and colleagues over a decade ago as major organizers of cellular immune response.

In a recent study, MacMicking’s team used advanced cryo-and electron microscope technology to visualize in high resolution the way GBPs…

Advances in understanding bat infection dynamics across biological scales

Posted by in categories: biological, biotech/medical

Bats are an important group of mammals to understand the ecology, diversity, and transmission of associated microbes – including viruses, bacteria, and fungi.


Over the past two decades, research on bat-associated microbes such as viruses, bacteria and fungi has dramatically increased. Here, we synthesize themes from a conference symposium focused on advances in the research of bats and their microbes, including physiological, immunological, ecological and epidemiological research that has improved our understanding of bat infection dynamics at multiple biological scales. We first present metrics for measuring individual bat responses to infection and challenges associated with using these metrics. We next discuss infection dynamics within bat populations of the same species, before introducing complexities that arise in multi-species communities of bats, humans and/or livestock. Finally, we outline critical gaps and opportunities for future interdisciplinary work on topics involving bats and their microbes.

Studies of bat-associated microbes (i.e. microorganisms detected in or isolated from bats) date back to rabies virus investigations in the early 1900s [1]. In the past two decades, following the emergence of Severe Acute Respiratory Syndrome (SARS) coronavirus (CoV) in 2003 and SARS-CoV-2 in 2019, there has been a dramatic increase in research on bat-associated microbes, including viruses, bacteria, haemosporidians and fungi [2–5]. These microbes may or may not cause disease in bats, and thus we broadly use the term ‘microbes’ rather than ‘pathogens’ throughout this paper to acknowledge that detecting microorganisms in bats is distinct from the process of determining pathogenicity [6].

Nanotech and Molecular Advances in Fighting Inflammation and Diabetes

Posted by in categories: biotech/medical, nanotechnology

Emerging nanotechnology and molecular innovations present promising strategies in combating inflammation and diabetes, aiming to transform treatment methods and improve patient outcomes significantly.


The intersection of nanotechnology and biomedicine has sparked significant advances in the treatment and understanding of both inflammatory and metabolic diseases. These advances have brought about innovative solutions to longstanding medical challenges, such as rheumatoid arthritis (RA) and type 2 diabetes mellitus (T2DM), diseases that collectively affect millions worldwide.

AI Reveals Brain Oscillations for Memory and Disease

Posted by in categories: biotech/medical, neuroscience, robotics/AI

Summary: A recent study showcases a significant leap in the study of brain oscillations, particularly ripples, which are crucial for memory organization and are affected in disorders like epilepsy and Alzheimer’s. Researchers have developed a toolbox of AI models trained on rodent EEG data to automate and enhance the detection of these oscillations, proving their efficacy on data from non-human primates.

This breakthrough, stemming from a collaborative hackathon, offers over a hundred optimized machine learning models, including support vector machines and convolutional neural networks, freely available to the scientific community. This development opens new avenues in neurotechnology applications, especially in diagnosing and understanding neurological disorders.

Newly discovered protein prevents DNA triplication

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

Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that, millions of times a day, a biochemical wonder takes place in the body: the copying of the DNA molecule. It is a high-precision job carried out by specific proteins and includes systems to protect against potential errors that could lead to diseases such as cancer.

One of these anti-failure systems has just been discovered by researchers in the DNA Replication Group at the Spanish National Cancer Research Centre (CNIO), led by Juan Méndez. It is based on a protein that ensures that DNA is copied only once, as it should be, and not twice or more.

The work is published in The EMBO Journal.

Using generative AI to improve software testing

Posted by in categories: biotech/medical, robotics/AI

Generative AI is getting plenty of attention for its ability to create text and images. But those media represent only a fraction of the data that proliferate in our society today. Data are generated every time a patient goes through a medical system, a storm impacts a flight, or a person interacts with a software application.

Using generative AI to create realistic around those scenarios can help organizations more effectively treat patients, reroute planes, or improve software platforms—especially in scenarios where real-world data are limited or sensitive.

For the last three years, the MIT spinout DataCebo has offered a generative software system called the Synthetic Data Vault to help organizations create synthetic data to do things like test software applications and train machine learning models.

Shape-shifting ultrasound stickers detect post-surgical complications

Posted by in categories: biotech/medical, health

Researchers led by Northwestern University and Washington University School of Medicine in St. Louis have developed a new, first-of-its-kind sticker that enables clinicians to monitor the health of patients’ organs and deep tissues with a simple ultrasound device.

When attached to an organ, the soft, tiny sticker changes in shape in response to the body’s changing pH levels, which can serve as an sign for post-surgery complications such as anastomotic leaks. Clinicians then can view these shape changes in real time through ultrasound imaging.

Currently, no existing methods can reliably and non-invasively detect anastomotic leaks—a life-threatening condition that occurs when gastrointestinal fluids escape the digestive system. By revealing the leakage of these fluids with high sensitivity and , the non-invasive sticker can enable earlier interventions than previously possible. Then, when the patient has fully recovered, the biocompatible, bioresorbable sticker simply dissolves away—bypassing the need for surgical extraction.

The Flu’s Hidden Weakness: New Antibodies Target “Dark Side” of Virus Protein

Posted by in categories: biotech/medical, health

Scientists at the National Institutes of Health have discovered antibodies that attack a difficult-to-detect area of the influenza virus, shedding light on the relatively unexplored “dark side” of the neuraminidase (NA) protein head. The antibodies target a region of the NA protein that is common among many influenza viruses, including H3N2 subtype viruses, and could be a new target for countermeasures. The research, led by scientists at the National Institute of Allergy and Infectious Diseases’ Vaccine Research Center, part of NIH, was recently published in the journal Immunity.

Influenza, or flu, sickens millions of people across the globe each year and can lead to severe illness and death. While vaccination against influenza reduces the burden of the disease, updated vaccines are needed each season to provide protection against the many strains and subtypes of the rapidly evolving virus. Vaccines that provide protection against a broad range of influenza viruses could prevent outbreaks of new and reemerging flu viruses without the need for yearly vaccine reformulation or vaccinations.

Alzheimer’s disease: Researchers devise experimental blood test

Posted by in categories: biotech/medical, neuroscience

A simple blood test picking up on biomarkers of Alzheimer’s disease could help experts diagnose this condition sooner and less invasively. However, the test has not yet been brought to market.
