Osaka, Japan - Despite what some people think, bone is not merely a passive component of the body. The skeleton is structurally dynamic and responds to life's physical stresses with continual equilibration between bone mass loss and reformation. This ensures healing and remodeling in tune with the ebb and flow of calcium and phosphorus in the bloodstream.
Below the verdant surface and organic rich soil, life extends kilometers into Earth's deep rocky crust. The continental deep subsurface is likely one of the largest reservoirs of bacteria and archaea on Earth, many forming biofilms - like a microbial coating of the rock surface. This microbial population survives without light or oxygen and with minimal organic carbon sources, and can get energy by eating or respiring minerals.
A team from the Department of Agronomy at the UCO has demonstrated, through field tests carried out during 8 agricultural seasons, that foliar feeding with fertilizer increases the concentration of zinc in wheat more than if it is applied to the soil
Scientists at the Victor Chang Cardiac Research Institute in Sydney have discovered a critical new gene that it is hoped could help human hearts repair damaged heart muscle after a heart attack.
Researchers have identified a genetic switch in zebrafish that turns on cells allowing them to divide and multiply after a heart attack, resulting in the complete regeneration and healing of damaged heart muscle in these fish.
Animals are remarkably diverse in their sleep and activity patterns due to foraging strategies, social behavior and their desire to avoid predators. With more than 3,000 types of cichlids, these freshwater fish may just be one of the most diverse species in the world. Lake Malawi alone, which stretches 350 miles through eastern Africa, is home to more than 500 cichlid species. They evolved from a few species that likely entered the lake about 3 million years ago and now display very different behaviors and inhabit well-defined niches throughout the lake.
Expressive language sampling (ELS) is a useful tool for measuring communication development in youth with Down syndrome, a new multi-site study has found.
Cyberbullying already accounts for one in four cases of bullying and, according to the latest UNICEF report issued on the occasion of 'Safer Internet Day', it affects at least two students per class in Spanish schools.
In all adult vertebrates, neural stem cells can be recruited to produce new neurons in the brain. However, little is known about these so-called "activation" processes.
Scientists at the Institut Pasteur, CNRS, and Tel Aviv University working in collaboration with the École Polytechnique and INRAE have successfully performed 3D visualization and spatial and temporal distribution analysis of neural stem cell activation in the adult brain of a zebrafish vertebrate model.
Researchers from Tokyo Medical and Dental University (TMDU) demonstrate an mRNA delivery system that effectively produces BDNF protein in rat brain to protect neurons from ischemia
A Curtin University study has found the introduced European honeybee could lead to native bee population decline or extinction when colonies compete for the same nectar and pollen sources in urban gardens and areas of bush.
Published in the 'Biological Journal of the Linnean Society', the research found competition between the native bees and the introduced European honeybee could be particularly intense in residential gardens dominated by non-native flowers, and occurred when the bees shared the same flower preferences.
Researchers at GMI - Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences - uncover an ingenious mechanism by which Arabidopsis safeguards the integrity of its genome. The paper is published in the journal Nature Cell Biology.

A team of archaeologists in north-west the Kingdom of Saudi Arabia has uncovered the earliest evidence of dog domestication by the region's ancient inhabitants.
The discovery came from one of the projects in the large-scale archaeological surveys and excavations of the region commissioned by the Royal Commission for AlUla (RCU).
The researchers found the dog's bones in a burial site that is one of the earliest monumental tombs identified in the Arabian Peninsula, roughly contemporary with such tombs already dated further north in the Levant.
It's like something out of science fiction. Research led by Bigelow Laboratory for Ocean Sciences has revealed that a group of microbes, which feed off chemical reactions triggered by radioactivity, have been at an evolutionary standstill for millions of years. The discovery could have significant implications for biotechnology applications and scientific understanding of microbial evolution.
Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. An international program conducted for nearly 20 years by scientists from the CNRS, the Université Paris-Saclay and the National museum of natural history with the support of the French polar institute, has determined that 5,200 tons per year of these micrometeorites reach the ground.
