- Imaging of nanoscale polar textures in quantum paraelectric SrTiO3
Cryo-STEM revealed periodic polar nanodomains in quantum paraelectric SrTiO3 below 105 K, but these domains fragmented below 40 K.
- Insulator-free topological photonic multi-lane highways
An insulator-free topological waveguide architecture comprising four inequivalent photonic valley half-semimetals arranged in a parallel, cyclic configuration and stacked very close to one another demonstrates robust, multi-lane, unidirectional light transport with 100% spatial efficiency.
- Google DeepMind: $40M commitment to the Genesis Mission for accelerating scientific discovery
Google DeepMind commits $40 million to the Genesis mission to accelerate scientific discovery.
- Programming the Internal Architecture of Synthetic Compartments by Coassembling Filamentous and Liquid DNA Phases
We demonstrate that DNA nanotubes and DNA condensates can be co-assembled within cell-sized compartments, including water-in-oil droplets and giant unilamellar vesicles (GUVs).
- Nova Capital invests $100m in UAE longevity platform
UAE-backed venture bets future of longevity lies not in standalone wellness brands, but in building ecosystem people never have to leave.
- Regulatory blind spots in the longevity economy
Nadine Esposito from Wellthspan Advisory explains why resilient longevity companies will outlast fast-growing ones.
- Dynamic hybrid-hydrogel lung models decouple matrix composition, stiffness, and fibroblast memory to define distinct drivers of fibrotic progression
The study separates the effects of matrix composition, stiffness, and fibroblast memory on fibrotic progression. This will help in better understanding the factors driving this disease progression.
- Randomized Spatial Barcoding for Time-Lapse Flow Cytometry
A new hydrogel-based platform enables tracking of suspended cells over multiple time points at the single-cell level using flow cytometry.
- Transmissible Cancer Discovered in Freshwater Fish
Researchers identified a form of transmissible cancer in freshwater fish species, where the cancer cells behave more like parasites than conventional tumors.
- New programmable photonic chip can control how fast light moves
Scientists have created a programmable optical chip that can slow down light on demand, giving engineers greater control over the propagation of optical signals in circuits.
- MIT Creates New Lidar Chip for Autonomous Cars with Wider View
MIT engineers have developed a new lidar chip that gives self-driving cars a wider view without relying on moving parts.
- The Computer That Helped Win World War II
One summer day in 1941, a British radio operator heard something unexpected in her headphones. A later report called it 'strange new music'. Sounding unlike the familiar Morse dit-dit-dah of enciphered messages sent over the German Enigma network, the 'new music' was a rhythmic warble of binary teletype code being transmitted at high speed.
- Continuous target-specific mutagenesis and rapid gene evolution by diversity-generating retroelements in Escherichia coli
Sequence-programmable directed evolution systems have great potential to accelerate bioengineering. Diversity-generating retroelements (DGRs) are natural hypermutation systems widely distributed in prokaryotes and bacteriophages with the capacity to introduce diverse mutations at template-specified sites of target genes.
- Author Correction: Multi-antigen-targeting T cells in pediatric central nervous system tumors: a phase 1 trial
This author correction note addresses an error in the original article published in Nature Medicine. It discusses the use of multi-antigen-targeting T cells for treating pediatric central nervous system tumors, highlighting its potential as a new therapeutic approach.
- Nature Medicine: Governing the social production of care: the hidden foundation of health systems
Health systems rely on unpaid care that is poorly measured and governed. We argue that unpaid care, and the wider social production system behind it, is a productive input whose breakdown drives avoidable admissions, delayed discharge, and labor-force exit.
- Beckett the Prophet
Author describes their typical day, starting with daily run at YMCA and ending with attention to a fellow club member.
- Using a Gaming PC's RTX 5070 from a Separate Linux Workstation
A user of HackerNews describes the process of using an RTX 5070 video card from a gaming PC on a separate Linux workstation.
- CRISPR–Cas regulates expression of embedded anti-phage defence systems
New approach using CRISPR–Cas allows transcriptional regulation of diverse innate defenses, balancing antiviral protection with fitness.
- The Heart Has a ‘Little Brain’ — and It Protects Against Stress
A subset of cardiac neurons keeps the heart from malfunctioning in stressed mice. The researchers found that certain subsets of these neurons are capable of protecting the heart against stress, even when the mouse is under extreme conditions.
- Semiconducting and magnetic lanthanide MXenes from intercalated halides
A bottom-up synthesis strategy creates lanthanide MXenes (Ln2CT2) that combine semiconducting behaviour with ferromagnetism, offering a promising new class of two-dimensional materials for spintronic applications.
