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......»»
Bat data study reveals conservation priorities in San Diego County
A team of wildlife managers at the U.S. Geological Survey in San Diego, California, working with a colleague from the San Diego Natural History Museum, have uncovered the areas in San Diego County that need the most scrutiny if bat populations in the.....»»
Scientists discover how innate immunity envelops bacteria
The protein GBP1 is a vital component of our body's natural defense against pathogens. This substance fights against bacteria and parasites by enveloping them in a protein coat, but how the substance manages to do this has remained unknown until now......»»
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.....»»
Is COVID-19 infecting wild animals? Researcher test species from bats to seals to find out
Over the course of the COVID-19 pandemic, researchers have found coronavirus infections in pet cats and dogs and in multiple zoo animals, including big cats and gorillas. These infections have even happened when staff were using personal protective e.....»»
New nanotherapy targets artery inflammation in cardiovascular disease
Inflammation of the arteries is a primary precursor and driver of cardiovascular disease—the No. 1 killer of people in the United States. This inflammation is associated with the buildup of dangerous plaque inside the arteries. Advanced treatments.....»»
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.....»»

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.....»»
The transition to a circular bioeconomy requires getting prices right, study says
Conventional food and agricultural production systems employ a linear "take, make, waste" approach: taking natural resources from the Earth to make food and fuel, generating waste that contaminates the soil and water, and emitting harmful pollutants......»»
Researchers link El Niño to accelerated ice loss in tropics
Natural climate patterns such as El Niño are causing tropical glaciers to lose their ice at an alarming rate, a new study has found......»»
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.....»»
New book brings prehistoric mammals to life
