Cellular exclusion of mitochondria protects cells from damage
Mitochondria are cellular organelles that generate most of the energy cells need to function, and thus play an important role in maintaining cell health. In a new study, researchers from Osaka University discovered a novel mechanism by which cells tu.....»»
Calcium transport protein in bacteria offers insights for drug development and food safety
Researchers at Umeå University have revealed details on how bacteria use calcium to regulate vital processes in a way that differs from human cells. This breakthrough is significant in the fight against antibiotic resistance and for increasing safet.....»»
Cells From Different Species Can Exchange ‘Text Messages’ Using RNA
Long known as a messenger within cells, RNA is increasingly seen as life’s molecular communication system—even between organisms widely separated by evolution......»»
Ammonia fuel cells see performance gains with new catalyst layer
The pursuit of clean and efficient energy conversion technologies has led to significant advancements in fuel cell research. A study conducted at Fuzhou University and published in Frontiers in Energy, presents a novel approach to enhance the perform.....»»
Eyeing the damage of hurricane season
In the aftermath of hurricanes like Helene and Milton, the damaging effects of these natural disasters are the center of national conversations, including questions about the long-term impact to infrastructure. However, current methods for damage ass.....»»
Scientists develop a new method to study gene function in cells and tissue
The Gaublomme lab has developed a new optical pooled screening approach called CRISPRmap, which enables the coupling of optical properties of single cells to targeted genetic perturbations. Optical phenotypes are typically inaccessible for sequencing.....»»
Why hurricanes like Milton in the US and cyclones in Australia are becoming more intense and harder to predict
Tropical cyclones, known as hurricanes and typhoons in other parts of the world, have caused huge damage in many places recently. The United States has just been hit by Hurricane Milton, within two weeks of Hurricane Helene. Climate change likely mad.....»»
Study proposes that proteins can compartmentalize and form droplets inside cells
In physics, a system composed of two substances can be modeled in accordance with classical mixture theory, which considers the fraction corresponding to each constituent and the interactions among constituents. Examples include the coexistence of hi.....»»
Experts warn "crazy busy" Atlantic hurricane season is far from over
Millions of people in the southeastern U.S. still are reeling from the catastrophic damage caused by Hurricanes Helene and Milton, but scientists warn that the Atlantic hurricane season is far from over......»»
Plant stem cells: Understanding the biological mechanism of growth control
Researchers from the University of Freiburg have identified the HAN molecule as an important regulator that controls plant growth in conjunction with WOX5. Understanding this mechanism is relevant for breeding more resilient or higher-yielding crops......»»
Oxidative stress: How protein recycling protects against cell death
Researchers at LMU University Hospital have discovered a new molecular switch that protects against cell death......»»
Expansion technique to image nanoscale structures inside cells makes high-resolution imaging more accessible
A classical way to image nanoscale structures in cells is with high-powered, expensive super-resolution microscopes. As an alternative, MIT researchers have developed a way to expand tissue before imaging it—a technique that allows them to achieve.....»»
Claustrophobic cells slow their own growth, forming beautiful patterns of concentric circles
Like so many organisms on the planet, when cells experience mosh-pit-level crowding, they may just become stressed. Yet unlike most other life forms, cells subject to physical stress from crowding by neighbors can find some relief by dramatically slo.....»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
From chaos to structure: How a bunch of seemingly disorganized cells go on to form a robust embryo
Pipetting liquids into tiny test tubes, analyzing huge datasets, poring over research publications—all these tasks are part of being a scientist. But breaking this routine is essential. Time away from the usual work environment can spark creative i.....»»
Assessment of damaged archaeological sites suggests they require individual protection concepts
An analysis of the damage to archaeological sites documented after a heavy rainfall event in July 2021 in parts of Germany shows that several factors increase the risk of damage to archaeological sites due to heavy rainfall and flooding events. For e.....»»
Scientists explore whether smaller chromosomes lead to more segregation errors during egg cell division
Three RIKEN researchers have shed light on the cellular mechanisms underlying chromosomal abnormalities that can cause miscarriages and congenital disorders such as Down syndrome......»»
Psychedelic Mushrooms Are Getting Much, Much Stronger
Cultivators are turning to genetic sequencing and cellular-manipulation techniques to breed highly potent mushrooms—leaving some unprepared psychonauts in distress......»»
Why Tampa Is So Vulnerable to Hurricane Milton
Tampa, Florida is the most vulnerable US city to hurricane damage. Delays to floodwater defenses and relentless development only made the situation worse......»»
You get your energy from your mom. A new study explains why
It's one of the basic tenets of biology: We get our DNA from our mom and our dad. But one notable exception has perplexed scientists for decades: Most animals, including humans, inherit the DNA inside their mitochondria—the cell's energy centers—.....»»
How Chlamydia pneumoniae bacteria use molecular mimicry to manipulate the host cell
Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own advantage. A team of biologists from Heinrich Heine University Düsseldorf (HHU), together with medical professionals and exper.....»»
