The frequency combs generate 5 mW of terahertz power covering a frequency range of almost 500 GHz and produce more than 70 lines at 3.5 THz.

Spontaneous parthenogenesis in sunflower has been used to develop a scalable doubled haploid breeding system.

Phase matching in the backward direction—the so-called nonlinear mirror effect—is demonstrated experimentally between the fundamental and second harmonic, using two distinct modes in a metal–dielectric–metal waveguide.

A genome-wide association meta-analysis of individuals with clinically assessed or self-reported depression identifies 44 independent risk loci. Comparisons with other psychiatric disorders and candidate gene analyses provide new insights into major depressive disorder.

In analogy with quantum Hall systems, it may be possible to find non-abelian anyons in the higher bands of Chern insulators. Now, the phase diagram of the second moiré band of twisted MoTe₂ is explored, laying the groundwork for such investigations.

Magnesium silicate perovskite, the dominant mineral in the lower mantle, is thought to transform into a post-perovskite phase in the mantle’s lowermost region. Laboratory experiments suggest substantial weakening could occur during the transformation from perovskite to post-perovskite, which could explain the anomalous physical properties of the lowermost mantle.

Fine-mapping of causal variants and integration of epigenetic and chromatin conformation data identify likely target genes for 150 breast cancer risk regions.

Whole-genome sequencing (WGS) can support drug resistance surveillance, but is rare in low- and middle-income countries. Here, the authors integrate WGS within the national antimicrobial resistance surveillance program in the Philippines and conduct a retrospective sequencing survey to characterize bacterial populations and dissect resistance phenotypes.

Shuman et al. report that epileptic mice harbor desynchronized hippocampal interneuron activity and unstable spatial representations, revealing that precise intrahippocampal synchronization is critical for spatial coding.

A multi-ancestry genome-wide association study meta-analysis, combined with transcriptome- and methylome-wide association analyses, identifies risk loci associated with colorectal cancer. Credible effector genes and their target tissues are also highlighted, showing that over a third probably act outside the colonic mucosa.

In a large-scale, international, multicenter, phase 1/1b trial, treatment of patients with advanced solid tumors with the B7H3-targeting antibody–drug conjugate YL201 was safe and showed preliminary clinical efficacy.

By simulating realistic doctor–patient conversations, a framework can be applied to large language models to investigate shortcomings and bias in patient interactions, providing insight before actual clinical deployment.

Most genetic studies have been done on European cohorts, which affects the efficacy of polygenic risk scores in non-European populations. Here, the authors demonstrate that a colorectal cancer PRS including Asian and European ancestries has improved performance over the European-centric PRS across racial and ethnic groups.
