DNA double helix on a light blue background with stylized human figures and skulls that read Homo sapiens, Neanderthals, Denisovans, Superarchaics, and Unknown hominins

Study points to two hidden human lineages in modern DNA

Researchers reported evidence for two previously unknown extinct human lineages in modern genomes.
One inferred lineage appears to have contributed DNA to all present-day people.
The second lineage is described as super-archaic and dates back nearly 2 million years.
The work uses living DNA to probe periods and regions where ancient DNA is scarce.

The genome of a long-extinct ancient human is hiding within us | New Scientist

Scientists say modern humans preserve DNA from a ghost ancestor

A new method suggests living humans collectively preserve nearly the full genome of a ghost ancestor.
Each person carries only a small fraction, but the inherited segments appear broadly distributed across the genome.
The approach could help reconstruct ancient lineages even when no fossil DNA is available.

AI trial shows retina imaging system improves inherited disease diagnosis

AI trial shows retina imaging system improves inherited disease diagnosis

Retina4IRD predicts 17 genotype categories from retinal images.
The model was trained and validated on data from 1,843 genetically confirmed patients across three countries.
In a randomized trial, AI-assisted specialists achieved 88.5% top-5 genetic accuracy versus 67.3% without the tool.

Genetically distinct avocados discovered in Nicaragua

Ancient migration may explain Nicaragua’s unusual avocados

Researchers analyzed avocado DNA from Nicaragua, Honduras and southern Mexico.
The study links Nicaragua’s avocados to a dispersal event tied to human migration about 5,000 years ago.
Scientists say the region’s avocado diversity may be useful for future conservation and disease resilience work.

Personalized RNA therapy shows early gains in rare SCN2A epilepsy

Personalized RNA therapy shows early gains in rare SCN2A epilepsy

Nature Medicine published two individualized SCN2A antisense case studies on July 21, 2026.
Researchers designed allele-selective ASOs to suppress mutant SCN2A transcripts while preserving the healthy copy.
The two patients showed seizure reductions, lower use of other medications, and developmental improvement.
Authors say longer-term follow-up is required to confirm disease-modifying benefit and scalability.

Links between genetics and cognition change across childhood

How Genetic Influences on Cognition Shift from Rare to Common Variants as Children Age

Rare DNA changes are most strongly linked to cognition in early childhood, but the link fades as children age.
Common DNA changes show stronger links to cognition later in childhood.
The study analyzed exome sequencing data from 6,495 children in the Children of the 90s cohort.
Findings may explain incomplete penetrance of rare variants associated with intellectual disability.

New tumor map identifies high-risk B-cell lymphoma standard therapy may miss

New Tumor Map Identifies High-Risk B-Cell Lymphoma Standard Therapy May Miss

Researchers combined genetic and proteomic analyses to identify aggressive DLBCL subtypes.
Standard R-CHOP therapy fails in over one-third of DLBCL patients due to molecular heterogeneity.
New tumor map can flag high-risk patients who may need alternative treatments like CAR T-cell therapy.
Experimental lab work identified potential therapeutic targets for aggressive subtypes.

More than 600 schizophrenia-associated genes uncovered by network model

Researchers link schizophrenia risk to 641 additional genes

Researchers analyzed data from more than 102,000 individuals and brain tissue from six regions.
The network model identified 641 previously unrecognized genes associated with schizophrenia.
Highlighted pathways include glutamate signaling, synaptic function, brain-cell communication, and immune processes.

These tiny genetic fragments may be critical for telling a brain when to rest

Microexons Linked to Hyperarousal and Sleep Loss in Zebrafish

Researchers linked altered neural microexons to hyperarousal in zebrafish.
Affected larvae showed heightened neural activity, changed swimming, and reduced sleep.
The work connects alternative splicing to the biological control of arousal.
Because arousal regulation is evolutionarily conserved, the findings may inform autism and schizophrenia research.

Newborn neurons routinely break then repair DNA during brain cortex formation, study reveals

Why Newborn Neurons Break and Repair DNA as the Brain Takes Shape

Researchers report that migrating newborn neurons in the developing cortex routinely incur double-strand DNA breaks.
The study links the damage to mechanical stress during migration and to the enzyme Topoisomerase IIβ.
Most of the observed DNA breaks were repaired within 24 hours through nonhomologous end joining.
The findings suggest severe DNA damage can be a normal, repairable part of brain development rather than only a sign of pathology.

I read the fine print on at-home DNA and health tests - watch out for these risks

At-home DNA kits promise insight but leave major privacy gaps

Policy disclosures for at-home test companies vary on privacy, regulation, and follow-up care.
Lab accreditation does not automatically answer questions about data rights or HIPAA coverage.
Genetic data can affect not only users but also relatives, making consent and disclosure more consequential.

What really happened when ancient humans migrated out of Africa

Rethinking the Out-of-Africa Migration: A Slow, Complex Journey

Genetic evidence confirms modern humans originated in Africa and spread globally, but the timing and nature of the migration are debated.
Archaeologist Huw Groucutt's study in Quaternary Science Reviews highlights a mismatch between genetic and archaeological data.
The out-of-Africa migration may have been a slow, prolonged process rather than a single event around 60,000 years ago.
A gradual dispersal would imply more complex interactions with other hominins like Neanderthals and Denisovans.

Genetic variants may blunt blood-sugar response to GLP-1 drugs

Researchers linked certain variants to weaker glycemic response to GLP-1 drugs.
The study estimates roughly 10% of people carry these variants.
The finding may help move diabetes treatment toward precision medicine.

Are we getting to the point where it's safe to gene-edit babies?

Base editing improves embryo CRISPR safety, but not enough

Base editing reduces the unwanted mutations associated with older CRISPR approaches.
Editing embryos requires near-perfect success because every cell descends from the embryo.
The reported advance is significant, but not enough to justify clinical use.

Adding a lower cutoff value for CA19-9 may identify additional high-risk cases of pancreatic cancer

Pancreatic Cancer Study Suggests Lower CA19-9 Threshold Could Catch More High-Risk Patients

Researchers say some pancreatic cancer patients are misclassified by the standard CA19-9 cutoff.
About 10% of patients may not elevate CA19-9 because of genetic nonproducer status.
The study examined 615 patients using whole-exome sequencing for FUT2 and FUT3 genotypes.
A dual-threshold model could help identify high-risk disease hidden within the normal range.

Study links loss of the X chromosome to lower odds of natural pregnancy

Researchers found higher loss of the X chromosome in blood cells among women with infertility.
A LOX level above roughly 0.9% was associated with reduced chances of natural pregnancy.
The study found no association between LOX and AMH, a common ovarian reserve marker.
The authors suggest LOX could eventually help guide timing for fertility treatment.
