Organic materials conduct ions in solids as easily as in liquids thanks to flexible sidechains

Normally, when liquids solidify, their molecules become locked in place, making it much harder for ions to move and leading to a steep decrease in ionic conductivity. Now, scientists have synthesized a new class of materials, called state-independent electrolytes (SIEs), that break that rule.

The paper is published in the journal Science.

Exclusive: Connectome Pioneer Sebastian Seung Is Building A Digital Brain

On a Sunday evening earlier this month, a Stanford professor held a salon at her home near the university’s campus. The main topic for the event was “synthesizing consciousness through neuroscience,” and the home filled with dozens of people, including artificial intelligence researchers, doctors, neuroscientists, philosophers and a former monk, eager to discuss the current collision between new AI and biological tools and how we might identify the arrival of a digital consciousness.

The opening speaker for the salon was Sebastian Seung, and this made a lot of sense. Seung, a neuroscience and computer science professor at Princeton University, has spent much of the last year enjoying the afterglow of his (and others’) breakthrough research describing the inner workings of the fly brain. Seung, you see, helped create the first complete wiring diagram of a fly brain and its 140,000 neurons and 55 million synapses. (Nature put out a special issue last October to document the achievement and its implications.) This diagram, known as a connectome, took more than a decade to finish and stands as the most detailed look at the most complex whole brain ever produced.

Efficacy of a Brief Cognitive Behavioral Treatment Across Body Image Distress Domains: Secondary Outcomes of the BRIGHT Randomized Clinical Trial

The BRIGHT program, a brief cognitive behavioral treatment, effectively reduced body image distress across multiple domains in head and neck cancer survivors.


This secondary analysis of a randomized clinical trial evaluates whether a brief, tailored cognitive behavioral treatment program is effective across multiple domains of head and neck cancer–related body image distress.

How ancient viral DNA shapes early embryonic development

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as “junk” plays a crucial role in the earliest moments of life. The research, published in Science Advances, begins to untangle the role of an ancient viral DNA element called MERVL in mouse embryonic development and provides new insights into a human muscle wasting disease.

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors’ genomes during infection. Today, these viral transposable elements make up around 8–10% of the mammalian genome.

Once disregarded as “junk” DNA, we now know that many transposable elements play an important role in influencing how genes are turned on and off, especially during early development. They have a variety of beneficial and harmful roles in the body, for example, some help regulate normal immune responses, while others can disrupt genes and contribute to diseases like cancer.

Epigenetic Age Prediction Remains Stable Across Common Variants and Diverse Ancestries

Epigenetic clocks, based on DNA methylation profiles at CpG sites, are widely recognized as reliable biomarkers of biological aging. However, common single-nucleotide polymorphisms (cSNPs), genomic variants that can overlap CpG sites, may affect DNA methylation profiles in ways that potentially interfere with the accuracy of epigenetic clocks. Moreover, because the prevalence of cSNPs varies across populations, such cSNP-CpG overlaps may differentially affect the age predictions of epigenetic clocks in diverse cohorts. Here, we present the first systematic cross-ancestry evaluation of cSNP robustness in the epigenetic clock, examining how cSNP-CpG overlaps affect the performance of epigenetic clocks across nine major genomic ancestry groups. We employed three complementary strategies: (a) testing whether cSNP-CpG overlaps are overrepresented in established epigenetic clocks or particular populations, (b) evaluating whether overlapping CpG sites correspond to the most influential aging predictors within clock models, and © simulating the effects of cSNP-associated methylation changes on predicted biological age. Our findings indicate that cSNP-CpG overlaps are not enriched among the CpG sites used in current epigenetic clocks, nor do they tend to involve the most influential sites. Furthermore, our simulation analysis revealed that current epigenetic clocks appear robust to cSNP-related methylation variations. Our findings underscore the overall stability of current epigenetic clocks, even in the presence of population-specific cSNP-CpG overlaps that are known to affect DNA methylation levels.

SpaceX sets plans for massive $20M H-E-B sized Texas project

So, essentially SpaceX’s new parking garage will be bigger than your local H-E-B (excluding the largest H-E-B in San Antonio of course). Construction on the garage began earlier this year in February, but it’s expected to be completed by January 7, 2027, according to the TDLR.

SpaceX’s Bastrop facility is a major manufacturing hub for its Starlink satellite internet service, producing terminals and components. It’s located across the street from Hyperloop Plaza, a Musk-owned shopping center which houses The Boring Company, and the new X (formerly Twitter) headquarters.

Number’s up: Calculators hold out against AI

The humble pocket calculator may not be able to keep up with the mathematical capabilities of new technology, but it will never hallucinate.

The device’s enduring reliability equates to millions of sales each year for Japan’s Casio, which is even eyeing expansion in certain regions.

Despite lightning-speed advances in artificial intelligence, chatbots still sometimes stumble on basic addition.
