How SARS coronaviruses reprogram host cells to their own benefit
Coronavirus researchers led by Professor Rolf Hilgenfeld of the University of Luebeck and PD Dr. Albrecht von Brunn of the Ludwig-Maximilian Universitaet (LMU) in Munich have discovered how SARS viruses enhance the production of viral proteins in inf.....»»
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......»»
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.....»»
These five "post-truth" claims are fueling the water wars in Australia
The contest between truth and post-truth matters when trying to solve big public policy questions. One of these questions is how to sustainably manage water in Australia for the benefit of all......»»
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.....»»
How the "social cost of carbon" measurement can hide economic inequalities and mask climate suffering
The social cost of carbon (SCC) is an essential tool for climate decision-making around the world. SCC is essentially a large cost-benefit calculation that helps policymakers compare the benefits of reducing carbon dioxide (CO2) emissions to the soci.....»»
Astronomers race to capture image of exoplanet near star
Planet AF Lep b is a world of firsts. In 2023, it was the lowest-mass planet outside our solar system to be directly observed and have its mass measured using astrometry. This is a technique that charts the subtle movements of a host star over many y.....»»
NASA announces a new class of space missions: Probe explorers
NASA has sent a whole host of spacecraft across the solar system and even beyond. They range from crewed ships to orbit and to the moon to robotic explorers. Among them are a range of mission classes from Flagships to Discovery Class programs. Now a.....»»
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.....»»
Why using a brand nickname in marketing is not a good idea
Researchers from Western University, Stockton University, and University of Massachusetts Amherst have published a new study that examines whether firms benefit from adopting popular nicknames in their branding efforts......»»
Cryo-electron microscopy provides new insights into the cell"s repair system
The membrane that surrounds cells in living organisms is extremely flexible and sensitive. How it protects itself from damage and renews itself is crucial for many life processes, and is not yet fully understood in detail. Scientists at Forschungszen.....»»
Scientists discover novel series of SARS-CoV-2 Mpro inhibitors for potential new COVID-19 treatments
New research from The Wistar Institute's Salvino lab, led by professor Joseph Salvino, Ph.D., has identified a novel series of SARS-CoV-2 Mpro inhibitors that may lead to potential new COVID-19 treatments that—according to preclinical testing—eff.....»»
Physics team uncovers a quantum Mpemba effect with a host of "cool" implications
Initially investigating out of pure curiosity, researchers have made a discovery that bridges the gap between Aristotle's observations two millennia ago and modern-day understanding, while opening the door to a whole host of "cool"—and "cooling"—.....»»
Study reveals how parasites thrive by balancing specialization with exploiting diverse species communities
A single shift of a parasite from one host species to another can trigger catastrophic infectious disease outbreaks. Despite this, scientists continue to debate the role of species diversity in natural environments on the spread of these parasites......»»
Nanopore technique shows transport mechanism of chaperone proteins at the single-molecule level
Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality......»»
Single-celled eukaryote employs unconventional cytoskeletal components for dynamic shape-shifting
Recently, a research group led by Prof. Miao Wei from the Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences discovered that Lacrymaria cells utilize unconventional and novel components of the cytoskeleton to achieve their remarkable.....»»
Colleges could benefit from taking a data-driven look at hostility toward Jews on campus
In the year that has passed since the Oct. 7 attack by Hamas on Israel, college campuses have been embroiled in debates about the resulting conflict. A major focus of these debates has been the surge in reports of antisemitic harassment of Jewish stu.....»»
During visit to South LA, EPA head vows to address environmental injustices in Watts
The head of the U.S. Environmental Protection Agency has pledged to work alongside Watts residents to address a host of environmental issues in the South Los Angeles community......»»
Trees" own beneficial microbiome could lead to discovery of new treatments to fight citrus greening disease
Citrus trees showing natural tolerance to citrus greening disease host bacteria that produce novel antimicrobials that can be used to fight off the disease, our recent study shows. We found the trees at an organic farm in Clermont, Florida......»»
