Combining simulations and experiments to get the best out of Fe3Al      (via sciencedaily.com)     Original source 

Researchers combined computer simulations and transmission electron microscopy experiments to better understand the ordering mobility and formation of microstructure domains in Fe3Al alloy. They were able to correlate structural changes with heat treatment to understand how particular mechanical behavior can be achieved. This is expected to allow the superelastic properties of Fe3Al to harnessed for the 3D printing of construction materials for absorbing seismic activity.

AIM algorithm enhances super-resolution microscope images in real time      (via sciencedaily.com)     Original source 

When trying to measure molecular structures with nanometer precision, every bit of noise shows up in the data: someone walking past the microscope, tiny vibrations in the building and even the traffic outside. A new processing technique removes noise from optical microscope data in real time, allowing scientists to track individual molecules over 10 times more precisely than was possible before.

Editing without 'cutting': Molecular mechanisms of new gene-editing tool revealed      (via sciencedaily.com)     Original source 

New research has determined the spatial structure of various processes of a novel gene-editing tool called 'prime editor.' Functional analysis based on these structures also revealed how a 'prime editor' could achieve reverse transcription, synthesizing DNA from RNA, without 'cutting' both strands of the double helix. Clarifying these molecular mechanisms contributes greatly to designing gene-editing tools accurate enough for gene therapy treatments.

Harnessing green energy from plants depends on their circadian rhythms      (via sciencedaily.com)     Original source 

Plant hydraulics drive the biological process that moves fluids from roots to plant stems and leaves, creating streaming electric potential, or voltage, in the process. A study closely examined the differences in voltage caused by the concentrations of ions, types of ions, and pH of the fluid plants transport, tying the voltage changes to the plant's circadian rhythm that causes adjustments day and night. According to the authors, this consistent, cyclic voltage creation could be harnessed as an energy source.

Observing mammalian cells with superfast soft X-rays      (via sciencedaily.com)     Original source 

Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.
