Water forms ‘spine of hydration’ around DNA, group finds

How water relates to and interacts with biological systems — like DNA, the building block of all living things — is of critical importance, and a research group has used a relatively new form of spectroscopy to observe a previously unknown characteristic of water.

Paper test strip could help heart failure patients monitor their condition at home

Contrary to the condition’s name, heart failure doesn’t mean the heart has stopped pumping — it’s just not working at full strength. It can often be managed with medications and lifestyle changes, but its progression needs to be monitored closely. Now scientists have developed a new test strip that could potentially allow patients to do this at home for the first time.

Special X-ray technique allows scientists to see 3-D deformations

Researchers have used an X-ray scattering technique called Bragg coherent diffraction imaging to reconstruct in 3-D the size and shape of grain defects. These defects create imperfections in the lattice of atoms inside a grain that can give rise to interesting material properties and effects.

Atomic structure of irradiated materials is more akin to liquid than glass

Materials exposed to neutron radiation tend to experience significant damage. At the nanoscale, these incident neutrons collide with a material’s atoms, which then collide with each other. The resulting disordered atomic network resembles those seen in some glassy materials, which has led many in the field to use them in nuclear research. But the similarities between the materials may not be as useful as previously thought.
