Michael Le Page explains how this “multi-region brain organoid” contains 80 per cent of the cell types found in a 40-day-old fetal brain.
The team behind it aims to study conditions like autism and schizophrenia — with some suggesting they could one day be used in artificial intelligence. But this all throws up major ethical issues…

In the world of medicine, the ability to listen to the intricate symphony of sounds within the human body has long been a vital diagnostic tool. Physicians routinely employ stethoscopes to capture the subtle rhythms of air moving in and out of the lungs, the steady beat of the heart, and even the progress of digested food through the gastrointestinal tract.
These sounds hold valuable information about a person’s health, and any deviations from the norm can signal the presence of underlying medical issues. Now, a groundbreaking development from Northwestern University is set to transform the way we monitor these vital sounds.
Researchers at Northwestern University have introduced a revolutionary soft, miniaturized wearable device that transcends the episodic measurements typically obtained during periodic doctor examinations. These innovative devices adhere gently to the skin, enabling continuous, wireless monitoring of crucial body sounds across multiple regions of the body simultaneously. This groundbreaking research was published in the prestigious journal Nature Medicine.
New therapies for managing aging could emerge from research into a new gene, which scientists have identified as a key driver of degeneration.
Age-related diseases are strongly linked to inflammation which, when chronic, albeit low-grade, contributes to conditions such as cardiovascular disease, diabetes, neurodegeneration, and sarcopenia, significantly impacting health and longevity.
In a study published in Nature Communications, Dr. Ildus Akhmetov, a geneticist at Liverpool John Moores University’s School of Sport and Exercise Sciences, along with colleagues from Italy, Switzerland, and the Netherlands, uncovered groundbreaking insights into the role of the Ectodysplasin A2 Receptor (EDA2R) in this process.
The Earth’s magnetic field, a constant presence in our environment, has a subtle yet profound impact on human health. It operates at extremely low frequencies (around 7.83 Hz, known as the Schumann resonance) and low intensities (30−60 microTesla). Generated by electric currents in the conductive iron alloys in Earth’s core, this magnetic field protects us from a blast of solar particles (solar wind) that could literally obliterate life on Earth if allowed to enter our atmosphere (Figure 1). It also plays a crucial role in regulating our circadian rhythms and supporting overall cellular function. Our cells are used to living bathed in this interactive field of magnetism and electricity, and therapeutically, we can turn this into our advantage.

Microbes, Ecology And Medicine — Dr. Sean M. Gibbons, Ph.D. — Associate Professor, Institute for Systems Biology (ISB)
Dr. Sean Gibbons, Ph.D. is Associate Professor at the Institute for Systems Biology (ISB — https://isbscience.org/people/sean-gibbons-phd/?tab=biography where his lab investigates how the structure and composition of evolving ecological networks of microorganisms change across environmental gradients, with a specific focus on how ecological communities in the gut change and adapt to individual people over their lifespans (i.e. host genotype, host development and host behavior) and how these changes impact human health (https://gibbons.isbscience.org/). His lab develops computational and experimental tools for investigating host-associated microbial communities to explore the interactions between ecology, evolution and ecosystem function, applying these insights to develop personalized interventions for improving human health and well-being.
Dr. Gibbons received his PhD in biophysical sciences from the University of Chicago in 2015, dual-advised by Jack Gilbert and Maureen Coleman. His graduate work focused on using microbial communities as empirical models for testing ecological theory.
Dr. Gibbons completed his postdoctoral training in Eric Alm’s laboratory in the Department of Biological Engineering at MIT from 2015–2018. His postdoctoral work focused on developing techniques to quantify individual-specific eco-evolutionary dynamics within the human gut microbiome.
Dr. Gibbons was awarded a Fulbright Graduate Fellowship to study microbiology and synthetic biology at Uppsala University in Sweden, where he earned a master’s degree in 2010. His PhD work was supported by an EPA STAR Graduate Fellowship. Upon joining the ISB faculty in 2018, his startup package was supported, in part, by a Washington Research Foundation Distinguished Investigator Award.
Yeast cells can be used to convert agricultural and forestry residues, as well as industrial byproducts, into valuable bioproducts. New and unexplored yeast strains may have properties that can enhance the commercial competitiveness of this sustainable production. In a study recently published in Applied and Environmental Microbiology, researchers collected and examined the biotechnological potential of 2,000 West African yeast strains.
The study—the first of its kind—is a collaboration between the University of Nigeria, Chalmers University of Technology, and the University of Gothenburg. It is based on a nationwide collection of samples from fruit, bark, soil, and waterways in Nigeria. This approach, known as bioprospecting, involves exploring various plants or microorganisms in nature to identify properties that can be utilized for different industrial or societal applications.
In this study, researchers searched for new yeast species with the potential use in industrial production of biochemicals, pharmaceuticals, and food ingredients.
You can learn a lot from a little slime mold. For Nate Cira, assistant professor of biomedical engineering in Cornell Engineering, the tiny eukaryotic organism provided inspiration for modeling “traveling networks”—connected systems that move by rearranging their structure.
Understanding these networks could help explain the structures and movements of certain biological systems and human organizations, from protein units that reassemble themselves to corporations expanding their product lines.
The findings were published Feb. 26 in Nature Communications.
