Structure-property relationships in nanoporous and amorphous iridium oxides

South Korean-based researchers have used first-principles quantum mechanical simulations to better understand the structure-property relationships in various polymorphic phases of iridium oxides to elucidate their outstanding performance in catalyzing the oxygen evolution reaction (OER). The OER is an important half-cell reaction where water is catalytically split to evolve oxygen. However, due to the intrinsic sluggish kinetics of the OER, this leads to an overall poor catalytic performance in general.

Creating heat-tolerant, stable boron nitride nanotube fibers

A Rice University team led by professors Matteo Pasquali and Angel Martí has simplified handling of the highly valuable nanotubes to make them more suitable for large-scale applications, including aerospace, electronics and energy-efficient materials. The researchers reported in Nature Communications that boron nitride nanotubes, aka BNNTs, assemble themselves into...

Microbiologists' work adds to research on microbiome fungi and childhood disease

A surge in research projects on the human microbiome—the complex ecosystem of microorganisms in the human gastrointestinal tract—is bolstering scientific understanding of health, disease and environment. Much of the research has focused on gut bacteria and viruses, leaving a third factor—fungi—little studied. An international consortium of...

Inside the jellyfish's sting: Exploring the micro-architecture of a cellular weapon

Summertime beachgoers are all too familiar with the painful reality of a jellyfish sting. But how do the stinging cells of jellyfish and their coral and sea anemone cousins actually work? New research from the Stowers Institute for Medical Research unveils a precise operational model for the stinging organelle of the starlet sea anemone, Nematostella vectensis. The study, published online in Nature Communications on June 17, 2022, was led by Ahmet Karabulut, a predoctoral researcher in the lab of Matt Gibson, Ph.D. Their work involved the application of cutting-edge microscopic imaging technologies along with the development of a biophysical model to enable a comprehensive understanding of a mechanism that has remained elusive for over a century. Insights from the work could lead to beneficial applications in medicine, including the development of microscopic therapeutic delivery devices for humans.

Finally, a Reason To Explain Why You Remember Scary Memories Most Vividly

When you think back on your most vivid memories, there are some obvious biggies that probably stick out, like, say, your graduation day and when you got married. But not all strongly remembered memories are ones you'd necessarily classify as positive. For instance, maybe you got in a car accident, and you find reminders of tough to shake. Well, according to recent research, there's a reason why you can likely remember scary memories in particular.

Hydrology controls lithium isotopes in rivers and seawater

Seawater lithium isotopes (δ7Li) record changes over Earth history, including a ~9‰ increase during the Cenozoic, which is interpreted as the reflection of either a change in continental silicate weathering rate or weathering feedback strength, associated with tectonic uplift. However, mechanisms controlling the dissolved δ7Li remain debated.

Chemists Reveal How Tau Proteins Form Alzheimer’s Disease Brain Tangles

Two types of tau proteins mix together in a nearly random way to generate the tangles seen in the brains of people with Alzheimer’s Disease. One of the hallmarks of Alzheimer’s disease is the presence of neurofibrillary tangles in the brain. These tangles, made of tau proteins, impair neurons’ ability to function normally and can cause the cells to die.
