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.....»»

Ocean currents threaten to collapse Antarctic ice shelves, study finds
A new study published in Nature Communications has revealed that the interplay between meandering ocean currents and the ocean floor induces upwelling velocity, transporting warm water to shallower depths. This mechanism contributes substantially to.....»»
Fox bones found in ancient Argentinian burial site might have been from a human pet
A team of archaeologists, anthropologists and evolutionary specialists from Argentina, the U.K. and Germany has found possible evidence of a tamed fox living with a human hunter/gatherer companion, approximately 1,500 years ago in what is now Argenti.....»»
In some classrooms in Senegal, deaf and hard-of-hearing students now study alongside everyone else
Mouhamed Sall stepped to the chalkboard with a glance and quick question in sign language to an assistant. Then he solved the exercise to the silent approval of his classmates, who waved their hands in a display of appreciation......»»
Mysterious bones may have belonged to gigantic ichthyosaurs
Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study carrie.....»»
Researchers develop mechanism of electrical 180° switching of Néel vector in spin-splitting antiferromagnet
A research team led by The Hong Kong University of Science and Technology (HKUST) and Tsinghua University has theoretically proposed a new mechanism of electrical 180° switching of Néel vector and experimentally realized it in antiferromagnetic mat.....»»
Scientists discover new phage resistance mechanism in phage-bacterial arms race
One of the most abundant and deadliest organisms on Earth is a virus called a bacteriophage (phage). These predators have lethal precision against their targets—not humans, but bacteria. Different phages have evolved to target different bacteria an.....»»
Chinese scientists reveal the spinning mechanism of the silkworm
Mulberry silk is a natural protein fiber that is light, soft and fine in nature, known as the "second skin of the human body" and "Queen of fibers." China is the origin of the world's sericulture industry......»»
Temple bones in the skulls of dinosaurs and humans alike were formed by feeding habits, study suggests
Whether human or reptile, in the skull of most terrestrial vertebrates there is a gaping hole in the temple; in the case of most reptiles, there are two. Scientists have been looking for explanations for this for 150 years......»»
Researchers discover corn reduces arsenic toxicity in soil
When crops grow in arsenic-contaminated soil, this toxic element accumulates in the food chain. A study involving the University of Basel has now discovered a mechanism used by corn plants to reduce arsenic uptake: the key factor is a special substan.....»»
Golfers" risk from pesticides used on turf grass is likely low, studies find
For many, spring heralds fresh air and exercise on the golf course. But do players risk exposure to unsafe levels of pesticides used to beautify and maintain a golf course's green grass?.....»»
Researchers observe anomalously bright single-molecule upconversion electroluminescence phenomenon
A research group has developed a new and highly efficient upconversion luminescence mechanism by scanning tunneling microscopy (STM) induced luminescence to observe an extraordinarily bright single-molecule upconversion electroluminescence (UCEL) phe.....»»
How to design and deliver an effective cybersecurity exercise
Armed forces have always utilized war-gaming exercises for battlefield training to prepare for times of conflict. With today’s digital transformation, the same concept is being applied in the form of cybersecurity exercises – tests and simulation.....»»
