New PET tracer shows promise for uPAR-targeted therapy of neuroendocrine neoplasms

A novel PET radiotracer can accurately assess the presence of a biomarker that indicates the level of tumor aggressiveness in neuroendocrine neoplasms (NENs). According to new research, the detection of the biomarker provides useful information for physicians to provide personalized care for patients with NENs and may also serve as a potential target for peptide radionuclide therapy (PRRT) for NEN...

System to create bioplastics

A team of scientists has developed a system that uses carbon dioxide, CO2, to produce biodegradable plastics, or bioplastics, that could replace the nondegradable plastics used today. The research addresses two challenges: the accumulation of nondegradable plastics and the remediation of greenhouse gas emissions.

Extreme nonlinear wave group dynamics in directional wave states

Deep-water wave groups are known to be unstable and become rogue. Such unstable wave groups propagate independently regardless of interference. Results seem to support the concept of an unperturbed nonlinear water wave group focusing in the presence of counter-propagating waves, suggesting wave states are directional.

Myotonic dystrophy: GABA receptors implicated in sleepiness, via mouse model

People with the inherited disorder myotonic dystrophy (DM) often experience excessive daytime sleepiness and fatigue, as well as altered responses to anesthetics that can put them at risk for complications when hospitalized. Researchers now have evidence from a mouse model of DM's central nervous system symptoms, indicating a link to the inhibitor neurotransmitter GABA -- and a potential...

Keeping cool: A common refrigerant shows promise for metal recycling

It's not uncommon in the scientific world for a process to have many unique applications. Researchers have taken a water treatment technology and adapted it for another environmentally important function -- selectively separating rare earth elements and transition metals. This chemical process significantly reduces both the energy and product consumption involved with rare earth element recovery.

Less bird diversity in city forests

A new study shows that cities negatively affect the diversity of birds. There are significantly fewer bird species in urban forests compared with forests in the countryside -- even if the forest areas are of the same quality.

New light for shaping electron beams

A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for adaptive electron microscopy, maximizing sensitivity while minimizing beam-induced damage.

Hackmanite mineral changes color also upon exposure to nuclear radiation

Researchers have long studied the color-changing properties of the natural mineral hackmanite upon exposure to UV radiation or X-rays. Now, the research group studied the reactions of synthetic hackmanite to nuclear radiation. The researchers discovered a one-of-a-kind and novel intelligent quality, gamma exposure memory, which allows the use of hackmanite as e.g. radiation detector.
