An early warning system for damage in composite materials

A team at the National Institute of Standards and Technology (NIST) has developed a tool to monitor changes in widely used composite materials known as fiber reinforced polymers (FRPs), which can be found in everything from aerospace and infrastructure to wind turbines. The new tool, integrated into these materials, can help measure the damage that occurs as they age.

Protection of cochlear synapses from noise-induced excitotoxic trauma by blockade of Ca2+-permeable AMPA receptors [Neuroscience]

Exposure to loud sound damages the postsynaptic terminals of spiral ganglion neurons (SGNs) on cochlear inner hair cells (IHCs), resulting in loss of synapses, a process termed synaptopathy. Glutamatergic neurotransmission via α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)-type receptors is required for synaptopathy, and here we identify a possible involvement of GluA2-lacking Ca2+-pe

Proteins containing ubiquitin-like (Ubl) domains not only bind to 26S proteasomes but also induce their activation [Biochemistry]

During protein degradation by the ubiquitin–proteasome pathway, latent 26S proteasomes in the cytosol must assume an active form. Proteasomes are activated when ubiquitylated substrates bind to them and interact with the proteasome-bound deubiquitylase Usp14/Ubp6. The resulting increase in the proteasome's degradative activity was recently shown to be mediated by Usp14's…

A new study by the University of Houston Institute for Research on Women, Gender & Sexuality (IRWGS) reports that women lag far behind men on multiple fronts in Harris County. Women are almost 50% more likely to live in poverty than men and the wage gap for men and women by race and ethnicity is considerably greater here than nationally. The report presents both new and summary analyses of select

Sudden cardiac death often a woman's first sign of heart disease

New research from the Center for Cardiac Arrest Prevention at the Smidt Heart Institute at Cedars-Sinai shows that rates of sudden cardiac arrest are rising following decades of a downward trend. While this disturbing uptick was observed in both sexes, in women the increase was mostly among those whose sudden cardiac arrest was the first manifestation of heart disease. In men, the increase was mos

Survey finds Americans strongly support organ and tissue donation for research

A strong majority of Americans agree that organ and tissue donation for research contributes to health and medical breakthroughs and acknowledge significant shortfalls for donation. This is according to a new survey released today commissioned by Research!America in partnership with The National Disease Research Interchange (NDRI).

Synaptotagmin 1 oligomers clamp and regulate different modes of neurotransmitter release [Neuroscience]

Synaptotagmin 1 (Syt1) synchronizes neurotransmitter release to action potentials (APs) acting as the fast Ca2+ release sensor and as the inhibitor (clamp) of spontaneous and delayed asynchronous release. While the Syt1 Ca2+ activation mechanism has been well-characterized, how Syt1 clamps transmitter release remains enigmatic. Here we show that C2B domain-dependent…

Synonymous codon substitutions perturb cotranslational protein folding in vivo and impair cell fitness [Biophysics and Computational Biology]

In the cell, proteins are synthesized from N to C terminus and begin to fold during translation. Cotranslational folding mechanisms are therefore linked to elongation rate, which varies as a function of synonymous codon usage. However, synonymous codon substitutions can affect many distinct cellular processes, which has complicated attempts to…

Tailoring spontaneous infrared emission of HgTe quantum dots with laser-printed plasmonic arrays

Near-to-mid infrared colloidal quantum dots offer a promising platform towards the realization of many useful devices including emitters, detectors, security and sensor systems. Normally, physics imposes some fundamental limitations at longer wavelengths, and their performance decreases as the radiative emission rate of the quantum dots drops. Scientists from Hong Kong/China, Russia and Australia

Technique can label many specific DNAs, RNAs, or proteins in a single tissue sample

A new technique can label diverse molecules and amplify the signal to help researchers spot those that are especially rare. Called SABER (signal amplification by exchange reaction), Peng Yin's lab at Harvard's Wyss Institute first introduced this method last year and since have found ways to apply it to proteins, DNA and RNA. Yin will explain how engineered DNA nanotechnology, including SABER, can

Tesla Computer Hardware Stuns Competitors: "We Cannot Do It"

Teardown Japanese business newspaper Nikkei Asian Review recently conducted a teardown of a Tesla Model 3, and engineers were shocked at how advanced the electric car company's onboard computer technology was. "We cannot do it," an unnamed Japanese engineer at a rival car company said after analyzing the Model 3's integrated central control unit, as quoted by Nikkei — referring to legacy automake

The {alpha}-synuclein hereditary mutation E46K unlocks a more stable, pathogenic fibril structure [Biophysics and Computational Biology]

Aggregation of α-synuclein is a defining molecular feature of Parkinson's disease, Lewy body dementia, and multiple systems atrophy. Hereditary mutations in α-synuclein are linked to both Parkinson's disease and Lewy body dementia; in particular, patients bearing the E46K disease mutation manifest a clinical picture of parkinsonism and Lewy body dementia,…
