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.

Flexible high-density microelectrode arrays for closed-loop brain–machine interfaces: a review

Flexible high-density microelectrode arrays (HDMEAs) are emerging as a key component in closed-loop brain–machine interfaces (BMIs), providing high-resolution functionality for recording, stimulation, or both. The flexibility of these arrays provides advantages over rigid ones, such as reduced mismatch between interface and tissue, resilience to micromotion, and sustained long-term performance. This review summarizes the recent developments and applications of flexible HDMEAs in closed-loop BMI systems. It delves into the various challenges encountered in the development of ideal flexible HDMEAs for closed-loop BMI systems and highlights the latest methodologies and breakthroughs to address these challenges. These insights could be instrumental in guiding the creation of future generations of flexible HDMEAs, specifically tailored for use in closed-loop BMIs.

How Nanotech Made an Old Leukemia Drug 22,000x Stronger

Structural nanomedicine — what helped give us the COVID vaccine — may now be the key to a potent blood cancer treatment that’s had remarkable early results.

The findings, published in ACS Nano, show that just two doses of the experimental therapy achieved 97.5% tumor growth inhibition in a human AML xenograft mouse model — 59-fold more effective than standard 5-fluorouracil (5-FU) treatment, with no observable side effects.

For a disease with a grim 29% 5-year survival rate — and a cure rate of only 15% in patients older than 70 years — the findings offer a glimpse of how rethinking drug structure, not just chemistry, could advance cancer care.

Mirkin frames the findings within what he calls “the era of structural nanomedicine,” the idea that how you arrange medicinal components at the nanoscale matters as much as the molecules themselves.

Circulating Ketone Bodies and Incident Cardiovascular Outcomes and Mortality: Insights From the UK Biobank

Higher ketone body levels are associated with increased cardiovascular events and mortality in a large population cohort. @paragchevli @DrMichaelShapir @wakeforestmed @WFCardiology

BackgroundKetone bodies (KB) are endogenous energy sources synthesized by the liver in response to metabolic stress. Their associations with atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), and mortality and their potential beneficial or harmful effects have yet to be determined. This study aimed to examine the association between KB and incident cardiovascular outcomes and mortality in a large general population cohort free from ASCVD and HF at baseline.
