Covalent bonding is a widely understood phenomenon that joins the atoms of a molecule by a shared electron pair. But in ...

Now, researchers have found the first evidence of changes taking place over the past 20 years in the shape of the inner core. Signs of the core’s deformation appeared in waves from earthquakes ...

The international team describes their results and the underlying molecular mechanism in Cell Metabolism. Ergothioneine is a natural compound found in certain fungi such as oyster or shiitake ...

The monomers were made up of molecules holding four extended aromatic groups, which gave them their X shape. Next, they layered these sheets in a crystalline structure and coaxed the ends of all ...

The universe could be boundless, continuing in all directions without end, or it could be sealed up in a compact shape such as a sphere or doughnut. Of course, modern scientists have wondered about ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

Rapid evolution creates uncertainty, however, which is why most communications leaders ponder these questions at the beginning of every year: What will shape the next 12 months, and how will our ...

Molecular evolution is the area of evolutionary biology that studies evolutionary change at the level of the DNA sequence. It includes the study of rates of sequence change, relative importance of ...

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules such as nucleic acids and proteins that carry out the biological ...

They have two dimensions – length and width. A polygon is a closed 2D shape with straight sides that meet at vertices. Polygons can be regular or irregular. If all the straight sides of a shape ...
