Hidradenitis Suppurativa and Smoking, Obesity, Psoriasis, Inflammatory Bowel Disease, and Systemic Sclerosis
Higher BMI and inflammatory bowel disease were causally linked to increased risk of HidradenitisSuppurativa, while the association with smoking was inconclusive after sensitivity analyses.
Question Is there an effect of body mass index (BMI, calculated as weight in kilograms divided by height in meters squared) and/or smoking on the risk of developing hidradenitis suppurativa (HS)?
Findings This mendelian randomization study including 3 592 596 patients found an effect of BMI on HS risk. Although initially a similar risk of smoking on HS was found, sensitivity analyses revealed inconclusive results potentially due to lack of power.
Meaning The findings of this study support a causal effect of increased BMI on the risk of developing HS; this information may help physicians better inform patients about disease risk contributed by modifiable lifestyle behaviors, knowledge that can be beneficial for planning subsequent lifestyle interventions.
Growing up with solid cooking fuels linked to long-term brain health risks
Exposure to indoor air pollution during childhood tends to be linked to poorer cognitive health in older adulthood. This suggests that access to clean energy early in life might help protect the brain as it ages. These findings come from a recent study published in Social Science & Medicine, which provides evidence that growing up in homes using solid fuels for cooking can set off a chain of disadvantages that affect memory and thinking skills decades later.
Xu Zong conducted the new study to explore a gap in our understanding of how early environmental exposures shape aging. While many scientists have established that breathing polluted air during adulthood increases the risk of cognitive decline, the long-term impact of breathing indoor air pollution during childhood remained mostly unexplored. Around the world, billions of people still rely on solid fuels like coal and wood for daily cooking and heating. This practice fills homes with toxic pollutants.
“I am interested in understanding how early-life living conditions, specifically indoor air pollution, may have long-term consequences for cognitive health. Air pollution has been highlighted by The Lancet as one of the modifiable risk factors for dementia. While much research has focused on adult exposures or urban outdoor pollution, there was a gap in linking childhood indoor environments to cognitive outcomes later in life,” said Zong, a researcher at the Max Planck – University of Helsinki Center for Social Inequalities in Population Health.

All-in-Focus Fourier Ptychographic Microscopy via 3D Implicit Neural Representation
Microscopy has long been essential to biomedical research, enabling detailed analyses of complex samples. Fourier ptychographic microscopy (FPM), a computational imaging technique, provides high-resolution, wide-field images without requiring extensive hardware modifications. However, current FPM algorithms struggle with samples exhibiting depth variations, such as tilted or 3-dimensional (3D) objects. The limited depth of field (DoF) leads to images with only focal-plane areas in sharp focus, while regions outside appear blurred. To address this limitation, we propose an all-in-focus FPM algorithm using physics-informed 3D neural representations to reconstruct sharp, wide-field images of 3D objects under limited DoF. Unlike previous methods, our approach samples the full depth range to create a 3D feature volume that incorporates spatial and depth information.
Novel prosthetic design combines AI and 3D printing to improve fit
A new, fully customizable 3D printed socket design is set to transform the prosthetics industry. The reimagined limb socket interface combines highly personalized pressure mapping with AI software and a lighter infill, creating a highly customized prosthetic that’s more comfortable to wear, for much longer, say researchers at Simon Fraser University.
Porcine IRF2 suppresses the cGAS-STING-mediated antiviral IFN signaling by competing IRF3 for binding to the IFN promoter
Sen Jiang et al. identify porcine IRF2 as a potent inhibitor of innate immune cGAS-STING-IRF3-IFN antiviral signaling pathway via systemic screenings, and they further dissected the mechanism of action by porcine IRF2 for negative regulation. This research unveiled a distinct function of IRF2 and provides justification for intervention of porcine viral diseases.
Consciousness Creates the Universe Says Roger Penrose
Read “” by James P. Kowall on Medium.
Watch this very interesting video in which Roger Penrose argues that Consciousness is fundamental and came first before it created the universe through a process of observation that turns potentiality into actuality:
For 400 years, we’ve believed that mindless matter eventually evolved into conscious minds. But what if we have the causation completely backwards? What if consciousness is the precondition for the universe?
In this video, we dive deep into the quantum paradox, wave function collapse, and the radical scientific theory that consciousness isn’t an accident of evolution — it’s the fundamental building block of reality itself. From the Copenhagen interpretation to the mysteries of the biological brain, we explore how quantum mechanics suggests the physical world is simply what appears when consciousness observes itself.
Large-Scale Neuromorphic Spiking Array Processors: A Quest to Mimic the Brain
Neuromorphic engineering (NE) encompasses a diverse range of approaches to information processing that are inspired by neurobiological systems, and this feature distinguishes neuromorphic systems from conventional computing systems. The brain has evolved over billions of years to solve difficult engineering problems by using efficient, parallel, low-power computation. The goal of NE is to design systems capable of brain-like computation. Numerous large-scale neuromorphic projects have emerged recently. This interdisciplinary field was listed among the top 10 technology breakthroughs of 2014 by the MIT Technology Review and among the top 10 emerging technologies of 2015 by the World Economic Forum.
