Brazil’s Genomas Brasil aims to bring precision medicine into public healthcare

Brazil’s Genomas Brasil aims to bring precision medicine into public healthcare

Brazil is embedding genomics into its universal public healthcare system through Genomas Brasil.
The effort combines sequencing, infrastructure and clinical implementation at national scale.
The program could become a model for genomic equity and precision public health in the global south.

South African genomics projects direct 10% of budgets to community-chosen benefits

South African genomics projects put 10% of budgets under community control

South African researchers described a genomics benefit-sharing model that allocates 10% of project budgets to community-selected initiatives.
The framework was presented at the World Congress of Bioethics and detailed in a Nature Communications paper led largely by African researchers.
The approach gives funders and institutions a concrete template for embedding ethical reciprocity into project design.

Long-read DNA test lifts rare disease diagnoses and could replace 15 other tests

Long-read DNA test boosts rare disease diagnoses

Long-read genome sequencing produced 3% more diagnoses in 1,000 patients.
Researchers say the test could replace 15 other standard diagnostics.
The study recommends using the method first for rare genetic disorders.

Koala population crash came before humans, genomic study reveals

Koala Population Crash Occurred 100,000 Years Ago, Before Humans Arrived, Genomic Study Finds

Koala population declined severely 100,000 years ago due to climate change, before humans arrived.
All modern koalas descend from a single ancestral population that survived glacial periods.
Genomic analysis of mutation rates allowed researchers to reconstruct population history.
Findings overturn earlier studies blaming human arrival for koala decline.

These tiny fish have a clever strategy to hide in plain sight – thanks to their food

Golden sweeper fish steals its bioluminescence from prey

Researchers say the fish lacks the luciferase gene needed to make its own light.
Whole-genome sequencing found no evidence of horizontal gene transfer.
The fish appears to acquire the light-producing protein from luminous ostracod prey.
The finding is presented as the first known case of this kind of kleptoproteinism.

Doubling their genomes may have helped plants survive mass extinctions

How duplicated genomes may have helped flowering plants outlast ancient catastrophes

Researchers identified 132 ancient genome-duplication events across 470 angiosperm species.
Those events clustered around major environmental disruptions, including the end-Cretaceous extinction era.
Extra genetic material may have given some plants more room to adapt during periods of extreme stress.

Saliva and gut microbes emerge as early warning signs for gastric cancer

Researchers found microbial signatures in oral and gut samples linked to gastric cancer.
Many enriched gut bacteria in cancer patients are typically found in the mouth.
Strain analysis suggested oral bacteria migrate into the gastrointestinal tract.
The microbial network was associated with lactic acid fermentation and a more tumor-friendly environment.

Study points to overlooked non-coding genes in newborn diabetes cases

Researchers say new causes of diabetes in babies were found in non-coding genome regions.
Older genetic studies focused mainly on protein-coding DNA.
The work could widen how neonatal diabetes cases are genetically investigated.

Evidence of monkeypox virus clade IIb lineage A.2.2 in the Republic of the Congo and co-circulation of clade Ia, Ib and clade IIb - Nature Medicine

Mpox surveillance in Congo identifies three viral clades circulating at once

Researchers report a confirmed mpox clade IIb lineage A.2.2 case in Pointe-Noire.
Passive surveillance in 2025 also identified clade Ia, clade Ib, and another clade IIb introduction.
The study argues for stronger surveillance, diagnostics, contact tracing, and affordable vaccines.

Mysterious RNA led scientists to a hidden layer of cancer

Mysterious RNA Discovery Reveals a Hidden Layer of Cancer Biology

Scientists discovered approximately 260,000 cancer-specific small RNAs across 32 tumor types, forming unique molecular barcodes
Machine learning models classified cancer types from RNA signatures with over 90 percent accuracy
About 5 percent of tested oncRNAs actively drive cancer progression, including metastasis
Roughly 30 percent of oncRNAs are secreted into the bloodstream, enabling potential liquid biopsy detection
Patients with high residual oncRNA levels after chemotherapy had nearly four-fold worse survival outcomes
