Mechanism by which exercise strengthens bones and immunity
Scientists have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study also shows that movement-induced stimulation is required for the maintenance of this niche, as well a.....»»
Preclinical study uncovers two proteins" crucial role in causing cancer cell growth
Scientists at City of Hope, one of the largest cancer research and treatment organizations in the United States, have discovered a new cellular mechanism that plays an important role in cancer cells' ability to cause disease. The study is published i.....»»
Team discovers mechanism that protects tissue after faulty gene expression
A study at the University of Cologne's CECAD Cluster of Excellence in Aging Research has identified a protein complex that is activated by defects in the spliceosome, the molecular scissors that process genetic information. Future research could lead.....»»
The secrets of tea plant immunity: Research identifies key phenolamides in battle against anthracnose
Tea anthracnose significantly impacts China's tea production, with no effective control methods currently available. Research has shifted towards phenolamides, secondary metabolites with potential disease resistance properties. Although these compoun.....»»
Plant receptors that control immunity and development share a common origin, study finds
Plants are continuously evolving new immune receptors to ever-changing pathogens. Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) have traced the origin and evolutionary trajectory of plant immune receptors. Their discovery wi.....»»
Researchers discover molecular mechanism that influences the symmetrical shape of the style
Humans are attracted to symmetry: in our buildings, our gardens, in our potential partners. For plants, the symmetrical shapes of organs are a matter of survival because the form directly impacts the function......»»
To stick or not to stick? Mixed sand columns illuminate design of better materials
Scientists from Tokyo Metropolitan University have been studying the strength and toughness of sand columns made of a mixture of sticky and non-sticky grains. They have uncovered the mechanism behind how the strength changes as grains are mixed in di.....»»
Scientists Just Discovered a New Type of Magnetism
In an atomically thin stack of semiconductors, a mechanism unseen in any natural substance causes electrons’ spins to align......»»
New simulation tool advances molecular modeling of biomolecular condensates
A University of Massachusetts Amherst team has made a major advance toward modeling and understanding how intrinsically disordered proteins (IDPs) undergo spontaneous phase separation, an important mechanism of subcellular organization that underlies.....»»
Ancient "relaxant-inflammatory" mechanism gets sponges moving
Did you know that sponges can move? While not exactly the champions of underwater acrobatics, sponges exhibit coordinated movements—despite not having muscles or neurons......»»
Team unravels activation mechanism of a protein that combats bacteria
The human immune system is constantly fending off a wide range of invaders—a feat that requires a diverse array of cellular troops and molecular weaponry. Although a great deal is already known about immune defense cells and the strategies they emp.....»»
Syphilis-like diseases were already widespread in America before the arrival of Columbus, new study finds
Researchers at the Universities of Basel and Zurich have discovered the genetic material of the pathogen Treponema pallidum in the bones of people who died in Brazil 2,000 years ago. This is the oldest verified discovery of this pathogen thus far, an.....»»
Study of gigantism in whales provides clues to genomic mechanism involved in tumor suppression
The functioning of certain regions of a few genes in cetaceans (whales, porpoises and dolphins) may explain why the Blue whale (Balaenoptera musculus) can reach lengths of up to 30 meters—almost 10 m more than a bus—while the Bottlenose dolphin (.....»»

Energy supply in human cells is subject to quality control, researchers discover
Researchers at the University Medical Center Göttingen (UMG) have discovered a new quality control mechanism that regulates energy production in human cells. This process takes place in mitochondria, the power plants of the cell......»»
Chilled-out tadpoles defy climate odds
University of Queensland researchers have discovered a previously unknown mechanism that allows tadpoles in cold environments to mitigate the detrimental effects of ultraviolet (UV) radiation......»»
It’s Time to Design for Repair
A Conversation With Jude Pullen Trying to repair almost anything can be a frustrating exercise. Repair is made more difficult by the way devices are designed and the ability to repair a device could be improved greatly if different design decisions.....»»
There’s a Huge Covid Surge Right Now and Nobody Is Talking About It
The US is in the midst of the largest Covid surge since Omicron, but with minimal testing and good population immunity, the wave is largely being ignored......»»

Elucidating the biosynthetic mechanism for protoberberine alkaloids from Coptis chinensis
Protoberberine alkaloids are a group of tetracyclic isoquinoline compounds known for their well-established antimicrobial and anti-inflammatory properties. Although protoberberine alkaloids are broadly found in various plant families such as Ranuncul.....»»
Climate change threatens fish supply: Tiny phytoplankton, big consequences
A research team that includes Dr. Angus Atkinson of the Plymouth Marine Laboratory and Dr. Axel Rossberg from Queen Mary University of London has discovered a hidden amplifying mechanism within the ocean's food web. Their findings, published in Natur.....»»
