LptM protein revealed as essential to outer membrane stability in bacteria

Gram-negative bacteria pose a significant threat to global health due to their high resistance to antibiotics compared to that of Gram-positive bacteria.

Bacteria use amyloids as molecular armor against predators

Amyloids are perhaps best known as a key driver of Alzheimer's disease.

High-resolution whole-cortex imaging reveals neurovascular dynamics in awake mice

Neurovascular coupling (NVC) is the dynamic regulation of cerebral blood flow in response to neural activity. Specifically, when neurons become active, nearby blood vessels dilate to increase blood supply, thereby meeting the heightened energy demands associated with neural activity.

AI-driven microscopy predicts and tracks protein aggregation in real time

The accumulation of misfolded proteins in the brain is central to the progression of neurodegenerative diseases like Huntington's, Alzheimer's and Parkinson's.

New insights reveal how FtsZ and ZapA cooperate during bacterial cell division

Bacterial cell division, a process wherein a single cell divides to form two identical daughter cells, represents one of the most essential biological processes.

New imaging technique reveals how cells organize glucose processing

In a scientific first, researchers from Vanderbilt University and the University of California, San Diego, have generated a high-resolution metabolic "map" of how cells orchestrate glucose processing, revealing a hidden world where organelles and molecular complexes collaborate when responding to a rush of nutrients.

Hungry bacteria choose food over danger in the human gut

Bacteria that cause intestinal infections typically avoid a stinky chemical - one that can kill them at high enough concentrations - inside human intestines, but they may actually swim toward it when a hearty meal is the reward.

Real-time protein misfolding detection by MiROM for cancer treatment monitoring

MiROM identifies proteins by using mid-infrared light to detect molecular vibrations – essentially the natural "dance" of molecules within protein structures. Unlike optical spectroscopy, which measures light attenuation, optoacoustics capture ultrasound waves generated when proteins absorb infrared light.

New imaging technique reveals mitochondrial activity inside live animals

In this study, researcher developed a new imaging approach that combines two powerful techniques to solve this problem. First, a special type of microscope called a two-photon microscope is used, which can look deep into live tissues with minimal damage.

New microchip tracks antibody-virus interactions from a single drop of blood

A new microchip invented by Scripps Research scientists can reveal how a person's antibodies interact with viruses-using just a drop of blood.

Scientists uncover hidden superfamily of lipid trapping proteins in bacteria

Scientists have identified a new type of protein in bacteria that could change our understanding of how these organisms interact with their environments.

Ireland's first and only BioBrillouin microscope installed at Trinity College Dublin

Trinity College Dublin now has Ireland's first and only BioBrillouin microscope, which will enable researchers to make giant strides in the fields of inflammation, cancer, developmental biology and biomedical materials, among others.

Real time imaging reveals how visual experience rewires the brain

Scientists have long known that the brain's visual system isn't fully hardwired from the start-it becomes refined by what babies see-but the authors of a new MIT study still weren't prepared for the degree of rewiring they observed when they took a first-ever look at the process in mice as it happened in real-time.

New tool reveals hidden water patterns in protein structures

Every protein in the body is encased in a water shell that directs protein structure, provides vital stability and steers function.

Study reveals intercellular flow as crucial factor in tissue mechanics

Water makes up around 60 percent of the human body. More than half of this water sloshes around inside the cells that make up organs and tissues. Much of the remaining water flows in the nooks and crannies between cells, much like seawater between grains of sand.
