New Evidence Shows Complex Life Began Far Earlier Than Previously Believed

Complex life began to develop earlier, and over a longer span of time, than previously believed, a groundbreaking new study has revealed.

Single-Cell RNA Imaging Uncovers Four Distinct Neuron Bands in the Hippocampus

Researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have identified a previously unknown pattern of organization in one of the brain's most important areas for learning and memory.

Study Exposes Ancestry Biases in Current Gene Annotations

Human gene maps contain major blind spots because they were built largely from the DNA sequences of people with European ancestry, according to a study published today in Nature Communications.

Engineered Gut Bacteria With MiRNA Nanoparticles To Reverse IBD

Biomimetic nanoparticles delivering microRNA to gut bacteria enhance protective metabolites, repair intestinal barriers, and alleviate colitis symptoms.

Light-Activated AR3 Triggers Alkalinity-Driven Apoptosis in Cancer Cells

One of the hallmarks of cancer cells is their ability to evade apoptosis, or programmed cell death, through changes in protein expression.

Harnessing Triploid Loquat to Unlock Aneuploid Diversity for Advanced Breeding

Triploid plants are widely valued in horticulture for desirable traits such as seedlessness, yield improvement, and stress resilience.

New Label-Free Breakthrough for Studying Bacterial Shape Diversity

Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can't be grown in the lab.

Unraveling How GFAP Mutations Disrupt Mitochondria in Alexander Disease

Some brain disorders are straightforward, such as the direct frontal lobe assault of a concussion or traumatic brain injury. Others, like Alexander disease, are akin to guerilla warfare.

Study Reveals ATM-Driven Mechanism Behind Telomere-Induced Senescence

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres-the protective caps at the chromosome ends-those caps eventually become too short to prevent chromosome ends from being recognized as DNA breaks.

Ambiguous Stop Codons Expand the Genetic Code in Archaea

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that's added to a chain of amino acids to make a protein.

Study Uncovers How Polyploid Plants Harness Transposons for Evolutionary Innovation

Polyploidization, the combination and duplication of genomes, is a major driver of plant evolution and diversification. Yet this process causes "genome shock," leading to rapid activation of transposable elements (TEs).

New Insight Into Light-Guided Growth of Bristleworm Eyes

A new study, led by the University of Vienna and the Alfred Wegener Institute in Bremerhaven, shows how the eyes of adult marine bristleworms continue to grow throughout life – driven by a ring of neural stem cells reminiscent of vertebrate eyes.

Hidden Messengers in the Blood

Every second, countless minute packages circulate through the bloodstream, transporting crucial data between the body’s cells.

CRISPR Technologies Transform On-Site Detection of Animal Pathogens

The rapid spread of animal diseases and pathogen evolution have long posed significant threats to the healthy development of animal husbandry.

Real-Time Visualization Reveals the Transcriptional Gearbox

Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins.

Bird flu withstands human fever

Avian influenza viruses pose a specific risk to people, as they can multiply at temperatures exceeding a normal fever, which is a defense mechanism used by the body to halt viruses, according to new research conducted by Cambridge and Glasgow universities.

New Regulatory Pathway Enhances Key Aroma Compound in Wine Grapes

β-Damascenone is a key norisoprenoid compound responsible for characteristic floral and fruity aromas in grapes and wines, particularly those from non-aromatic varieties such as Cabernet Sauvignon and Merlot.

Study Identifies Adipogenin as Crucial Driver of Lipid Droplet Formation

A microprotein called adipogenin appears to play a key role in helping fat cells store lipid droplets – a phenomenon that's pivotal for metabolic health, a study co-led by UT Southwestern Medical Center researchers shows.

Gene Transcription Start Sites Identified as Hidden Mutational Hotspots

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we study genetics and disease.

UBQLN2 Liquid Droplets Found to Catalyze Early α-Synuclein Aggregation

Parkinson's disease (PD) is an age-related, progressive neurodegenerative disorder. The hallmark of PD pathogenesis is the Lewy bodies (LBs) that accumulate in neurons in the substantia nigra region of the brain, damaging these neurons and leading to the motor symptoms of the disease. α-synuclein (α-syn), a misfolded protein, aggregates and forms fibrils, which leads to the formation of LBs.
