Medical Xpress / Cerebrospinal fluid motion in the brain captured in remarkable detail

Cerebrospinal fluid (CSF) is a clear and watery liquid that flows in and around the brain and spinal cord. Its functions include protecting parts of the nervous system, delivering nutrients and removing metabolic waste.

Phys.org / Climate change is now warming the deepest parts of the Arctic Ocean

While it is well known that climate change is heating the world's oceans, it was thought that the deep sea was safe from its effects—until now. Researchers have discovered that a rapidly warming part of the Atlantic is ...

Phys.org / Atoms passing through walls: Quantum tunneling of hydrogen within palladium crystal

At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy than the energy of the ...

Phys.org / Unlocking the genome's hidden half with new DNA sequencing technology

Cornell researchers have found that a new DNA sequencing technology can be used to study how transposons move within and bind to the genome. Transposons play critical roles in immune response, neurological function and genetic ...
