Micro- and nanoplastics facilitate the propagation of antimicrobial resistance in mixed microbial consortia
Zhen et al. show that micro-/nanoplastics increase antimicrobial resistance gene abundance and mobilization in mixed microbial consortia. Nanoplastics intensify oxidative stress and SOS responses and strengthen ARG-MGE co-localization, promoting dense horizontal gene transfer networks and turning plastisphere biofilms into resistance hotspots.
Telomere-to-telomere assembly detects genomic diversity in Canadian strains of Borrelia burgdorferi
Amin et al. present telomere-to-telomere assemblies of nine Borrelia burgdorferi strains from Canada, uncovering the diversity at chromosome ends and plasmid profiles. They identify an lp28-1a plasmid subtype and detect plasmid-chromosome recombination, offering insights into genomic plasticity and potential mechanisms of adaptation in Borrelia.
Purified diets enable experimental rigor through compositional control in animal research
Purified diets offer compositionally defined platforms that improve causal inference in nutrition studies. When aligned with the biological question, they enable targeted nutrient loss- and gain-of-function experiments, systematic lipid-source swaps, and the discovery of diet-microbiome-drug interactions. We recommend complementary validation in grain-based chow or human-relevant diets to maximize translational relevance.
Could a niche 80s technology be the key to better quantum computers?
Superconducting computing circuits were briefly heralded as the future of computing in the 1980s. Columnist Karmela Padavic-Callaghan visits a quantum chip foundry where one company is betting this technology’s second act will revolutionise quantum computers.

Wastewater Methane Gaps Found in National Climate Reports
“If you don’t know exactly how much emissions you have, then it’s really difficult to make effective policies or technologies or methods to reduce the emissions,” said Dr. Z. Jason Ren.

Are national climate reports missing crucial data points regarding wastewater greenhouse gas (GHG) emissions? This is what a recent study published in Nature Climate Change hopes to address as a team of researchers investigated the accuracy of national inventory reports (NIRs) for wastewater GHG. This study has the potential to help researchers, climate scientists, legislators, and the public better understand the methods for tracking climate change and steps that can be taken to fill the gaps in report lapses.
For the study, the researchers obtained data from 38 countries regarding wastewater GHG emissions with the goal of ascertaining existing data gaps in NIRs. The motivation of this study comes from the lack of consistent data methods and large changes that occur over many years and in global regions. The overarching goal of the study was to ascertain where the data gaps exist and how to fill them.
In the end, the researchers discovered massive data gaps in wastewater GHG emissions, including an unreported gap of 52.0–73.2 million metric tons (MMT) of CO2-equivalent (CO2e) annually across the 38 countries. Additionally, they found that global gap of 94–150 MMT CO2e annually.
Engineered immune therapy could help fight brain aging
Researchers at Stanford University engineered a modified version of the immune protein interleukin-10 (IL-10) that retains only its anti-inflammatory properties while eliminating its pro-inflammatory ones. When injected into aged mice, this modified protein stimulated the growth of new neurons and improved performance on memory and learning tasks, such as maze navigation and object recognition. The study, published in Immunity, suggests that age-related cognitive decline is linked to the accumulation of exhausted T-lymphocytes in the brain, chronic inflammation, and impaired microglial function — all of which reduce neurogenesis. The findings indicate that selectively modulating immune signaling could open new avenues for treating neurodegenerative diseases. The team plans to further investigate the protein’s mechanisms and explore ways to target specific cell types more precisely to minimize potential side effects.
A modified immune protein developed by Stanford researchers points to a novel strategy for combating age-related cognitive decline.
The unbearable hardness of deciding about magic
Identifying the boundary between classical and quantum computation is a central challenge in quantum information. In multi-qubit systems, entanglement and magic are the key resources underlying genuinely quantum behaviour. While entanglement is well understood, magic — essential for universal quantum computation — remains relatively poorly characterised. Here we show that determining membership in the stabilizer polytope, which defines the free states of magic-state resource theory, requires super-exponential time $\exp( n^2)$ in the number of qubits $n$, even approximately. We reduce the problem to solving a $3$-SAT instance on $n^2$ variables and, by invoking the exponential time hypothesis, the result follows. As a consequence, both quantifying and certifying magic are fundamentally intractable: any magic monotone for general states must be super-exponentially hard to compute, and deciding whether an operator is a valid magic witness is equally difficult. As a corollary, we establish the robustness of magic as computationally optimal among monotones. This barrier extends even to classically simulable regimes: deciding whether a state lies in the convex hull of states generated by a logarithmic number of non-Clifford gates is also super-exponentially hard. Together, these results reveal intrinsic computational limits on assessing classical simulability, distilling pathological magic states, and ultimately probing and exploiting magic as a quantum resource.
