Light-Based Technique Reveals How Extracellular Vesicles Interact With Cells

The tiny bubbles that carry signals between cells throughout the body were discovered decades ago, but precisely what they contain and how their cargo affects recipient cells is still largely a mystery.

Visualizing How Cancer Seed Cells Evade Brain Immunity

Metastasis occurs when cancer cells break away from the original tumor and travel through the bloodstream to form new tumors in other parts of the body. It is the leading cause of cancer-related death. Brain metastasis is particularly severe and affects 10-30% of patients with advanced lung, breast, and melanoma cancers.

OIST Study Illuminates Cancer's Avoidance of Cellular Stress Responses

When cell division (mitosis) takes too long, it can be a sign that something is wrong with the cells, for example DNA damage or chromosomal instability.

Scientists Discover First Human DNA-Cutting Enzyme That Responds to Tension

An international research team at the University of Hong Kong has discovered a human protein known as ANKLE1, which is recognized as the first DNA-cutting enzyme (nuclease) in mammals that can detect and respond to physical tension in DNA.

Breaking the Interspecies Immune Barrier to Advance Human Organ Generation

Failure of human pluripotent stem cells (PSCs) to survive when grown with the PSCs of distantly related species occurs because of an innate immune reaction in the nonhuman cells, a study led by UT Southwestern Medical Center researchers suggests.

MiniVolt Microscope Captures Neuron Voltage Signals in Freely Moving Animals

Researchers have built a tiny, lightweight microscope that captures neuron activity with unprecedented speed that can be used in freely moving animals.

Researchers Capture the Most Detailed Images of Molecules in Chromatin Condensates

A team of researchers led by HHMI Investigator Michael Rosen has captured the most detailed images yet of the molecules in chromatin condensates — droplet-like structures of compacted DNA.

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.

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.

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.

Decoding the Interaction Between SV2A Protein and Anti-Epileptic Drugs

A multi-institute team led by St. Jude Children's Research Hospital and UT Southwestern Medical Center investigators established for the first time how certain drugs used to treat epilepsy affect their target.

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.

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.

Researchers Uncover How Methamphetamine Suppresses Dopamine Clearance

Dopamine brings on a surge of pleasure, but too much dopamine in a synapse can ultimately lead to mood disorders and addiction.

Scientists Reveal How Memory T Cells Persist Across the Body

Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again.

Optogenetic Tool Uncovers Key Role of Mechanical Forces in Early Embryonic Development

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear.

New Study Finds Higher Levels of Antimicrobial Resistance (AMR) in Surface Water During Winter

A new study from The James Hutton Institute, Scotland’s pre-eminent interdisciplinary scientific research institute for the sustainable management of land, crop and nature resources, has found that the levels of antimicrobial resistance (AMR) present in surface water increase during winter.

Chaperone-Shielding Mechanism Regulates Protein Glycosylation

Proteins are often called the building blocks of cells, but even those building blocks need to be built. One of the most important steps in the process of building proteins is glycosylation, when sugar molecules (glycans) are attached to the maturing protein.

Newly Identified Mitochondrial DNA Damage Sheds Light on Cellular Stress

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress.
