Treating the ‘root’ cause of baldness with a dissolvable microneedle patch

Posted: 11 Aug 2021 01:28 PM PDT

Although some people say that baldness is the 'new sexy,' for those losing their hair, it can be distressing. An array of over-the-counter remedies are available, but most of them don't focus on the primary causes: oxidative stress and insufficient circulation. Now, researchers have designed a preliminary microneedle patch containing cerium nanoparticles to combat both problems, regrowing hair in a mouse model faster than a leading treatment.

A robotic fish tail and an elegant math ratio could inform design of next-gen underwater drones

Posted: 11 Aug 2021 01:28 PM PDT

Researchers built a fishlike robot that uses a programmable artificial tendon to tune its own tail stiffness while swimming in a water channel. The results were impressive: The robot could swim over a wider range of speeds while using almost half as much energy as the same robot with a fixed-stiffness tail.

Physics researchers at the University of North Florida's Atomic LEGO Lab discovered a new electronic phenomenon they call 'asymmetric ferroelectricity'. The research demonstrated this phenomenon for the first time in engineered two-dimensional crystals.

Tiny bubbles: Treating asthma with gene silencing nanocapsules

Posted: 11 Aug 2021 10:14 AM PDT

Researchers are developing novel asthma therapeutics using gene-silencing nanocapsules in a bid to help patients who aren't benefiting from existing treatments.

Future battery cost: Crucial for the success of the mobility and energy transition

Posted: 11 Aug 2021 10:12 AM PDT

A group of researchers has published a comparative study of battery cost predictions from the past decade. In the study, assumptions from more than 50 scientific publications that analyze the costs of lithium-ion, solid-state, lithium-sulfur and lithium-air batteries, resulting costs are compared and the academic opinion is consolidated into a cost trend.

A clean US hydrogen economy is within reach, but needs a game plan, energy researchers say

Posted: 11 Aug 2021 08:31 AM PDT

Addressing climate change requires not only a clean electrical grid, but also a clean fuel to reduce emissions from industrial heat, long-haul heavy transportation, and long-duration energy storage. Hydrogen and its derivatives could be that fuel, argues a recent commentary , but a clean U.S. H2 economy will require a comprehensive strategy and a 10-year plan. The commentary suggests that careful consideration of future H2 infrastructure, including production, transport, storage, use, and economic viability, will be critical to the success of efforts aimed at making clean H2 viable on a societal scale.

Anatomy of an earthquake series

Posted: 11 Aug 2021 08:31 AM PDT

A new study focuses on the 2013 seismic sequence at the Castor platform of a former oil field, about 20 km offshore the coast of Valencia, Spain. During the initial phase of the development of a gas storage facility in the former oil field, thousands of earthquakes with magnitudes below 4.1 took place after the injection of gas into the depleted layers of the reservoir.

A novel virtual reality technology to make MRI a new experience

Researchers have created a novel interactive VR system to be used by patients when undertaking an MRI.

Striking gold: A pathway to stable, high-activity catalysts from gold nanoclusters

Posted: 10 Aug 2021 03:45 PM PDT

Precise metal nanoclusters (NCs) are ideal for developing practical catalysts for chemical reactions. However, their catalytic activity is reduced either due to protective molecules called 'ligands' surrounding them or aggregation resulting from ligand removal. In a new study, scientists elucidate the ligand removal mechanism for gold NCs and irradiate them with UV light to prevent aggregation, creating a high-functioning photocatalyst.

Computational evaluation of drug delivery reveals room for inhalers improvement

Posted: 10 Aug 2021 08:09 AM PDT

Increased air pollution in recent years has exacerbated health risks for people who suffer from pulmonary diseases and these dynamics underscore the importance of increasing the efficacy of drug delivery devices that administer active pharmaceutical ingredients to treat respiratory illnesses. Researchers describe developing a computational evaluation of drug delivery through both pressurized metered-dose inhalers and dry powder inhalers to determine how the process can be improved.

Novel molecular imaging technique casts complex coordination molecules in a new light

Posted: 06 Aug 2021 12:58 PM PDT

High-angle annular dark-field scanning transmission electron microscopy can be used to determine complex conformational structures of both crystalline and amorphous polynuclear non-planar coordination molecules, scientists have shown. Using iridium as a tracer metal, they were successful in determining the different conformations of a highly branched coordination compound molecule. This has opened up possibilities for imaging and designing of complex inorganic and organic molecules.
