Urgent need to find safe ways for patients to withdraw from antidepressants, survey finds

More than 4 million Australians received mental health-related prescriptions in 2018-19 some 70% of which were for antidepressants Despite millions of Australians taking antidepressants each day – using them at the second highest rate out of all OECD countries – there is little high quality evidence on safe and effective ways to stop treatment.The findings come from the latest review published...

Transient grating spectroscopy with ultrafast X-rays

Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in looking inside materials using the method of transient grating spectroscopy with ultrafast X-rays at SwissFEL. The experiment at PSI is a milestone in observing processes in the world of atoms. The researchers are publishing their research results today in the journal Nature Photonics.

Plastic: What we eat and breathe

Take a deep breath, drink a glass of water, eat a snack. If you do any of these things, it's likely that you are also inhaling and ingesting tiny particles of plastic, as much as a credit card's weight each week. Plastic pollution is everywhere, including in our bodies.

Under pressure: Manipulating protein-mimicking molecules with hydrostatic pressure

Stimulus-responsive supramolecular structures have emerged as an alternative to conventional ones, owing to their applications in sensing, drug delivery, and switchable memory systems. Now, scientists at Tokyo Institute of Technology explore the hydrostatic-pressure response of 'foldamers'—artificial molecules that mimic protein folding—and report a shift in their preferred conformation with...

Photoexpansion: Bio-based polyesters hard film

Polymers that exhibit their functions by light have been studied for a few decades because they enable device miniaturization, energy saving, and precise signal control. Polymers based on azobenzene, diarylethene, etc. are the pioneers, and many examples of light-driven motors and artificial muscles have been reported. On the other hand, cinnamic acid, which is a constituent of lignin in natural...
