Scientists discover gene therapy provides neuroprotection to prevent glaucoma vision loss

Eurekalert - Jul 22 2021 - 00:07
A form of gene therapy protects optic nerve cells and preserves vision in mouse models of glaucoma, according to research supported by NIH's National Eye Institute. The findings suggest a way forward for developing neuroprotective therapies for glaucoma, a leading cause of visual impairment and blindness.

Geneticists reveal how mutation causes childhood cancer; use drug to reverse its effects

Eurekalert - Jul 22 2021 - 00:07
Geneticists from Trinity College Dublin have discovered how a specific genetic mutation (H3K27M) causes a devastating, incurable childhood cancer, known as diffuse midline glioma (DMG), and - in lab studies working with model cell types - successfully reverse its effects to slow cancer cell growth with a targeted drug. Their landmark work - just published in leading international journal, Nature Genetics - translates crucial new understanding of the genetics of DMG progression into a highly promising, targeted therapeutic approach and offers significant hope of improved treatments in the future.

Disagreement may be a way to make online content spread faster, further

Eurekalert - Jul 22 2021 - 00:07
Disagreement seems to spread online posts faster and further than agreement, according to a new study from the University of Central Florida.The finding comes from an examination of posts labeled controversial on social news aggregation site Reddit. To perform the study, the researchers analyzed a Reddit dataset that was collected by DARPA.

'Golden nail': Quarry near Salzgitter becomes global geological reference point

Eurekalert - Jul 22 2021 - 00:07
Scientists from Goethe University Frankfurt, University of Warsaw, State Authority for Mining, Energy and Geology in Hanover, and from other institutions have found in Salzgitter-Salder what researchers have been searching for for more than 20 years: A geological formation that perfectly represents the transition from the Cretaceous Turonian to the Coniacian Age. The former limestone quarry is now considered a global reference point (GSSP) for the turn of the ages 89.4 million years ago.

3D imaging reveals neural 'vicious cycle' in fatty liver disease

Eurekalert - Jul 22 2021 - 00:07
With the application of a novel three-dimensional imaging technology, researchers at Karolinska Institutet in Sweden have discovered that one portion of the autonomic nervous system in the liver undergoes severe degeneration in non-alcoholic fatty liver disease. The study, which is conducted in mice and human liver tissue, shows that the degeneration of nerves is correlated with the severity of liver pathology. The results are being published in the journal Science Advances.

NTU Singapore scientists develop tougher, safer bicycle helmets using new plastic material

Eurekalert - Jul 22 2021 - 00:07
Researchers from Nanyang Technological University, Singapore (NTU Singapore), in collaboration with French specialty materials leader Arkema, have developed a tougher, safer bicycle helmet using a combination of materials. The new helmet prototype has higher energy absorption, reducing the amount of energy transferred to a cyclist's head in the event of an accident and lowering the chances of serious injury.

HKU scientists harness the naturally abundant CRISPR-Cas system to edit superbugs with the hope of treating infections caused by drug resistant pathogens

Eurekalert - Jul 22 2021 - 00:07
A joint research team from the University of Hong Kong reported the development of a transferrable and integrative type I CRISPR-based platform that can efficiently edit the diverse clinical isolates of Pseudomonas aeruginosa, a superbug capable of infecting various tissues and organs and a major source of nosocomial infections. The technique can accelerate the identification of resistance determinants of multidrug resistant (MDR) pathogens and the development of novel anti-resistance strategies.

Alzheimer-linked enzyme complex 'buckles up' for safe trip through the cell

Eurekalert - Jul 22 2021 - 00:07
A research team led by Wim Annaert (VIB-KU Leuven) uncovered the early assembly of gamma-secretase, a protein complex linked to numerous cellular processes including the development of Alzheimer's disease. In a first step, two dimeric subcomplexes are formed, which independently exit the ER and only afterwards assemble into a four-subunit complex. This 'buckle up' mechanism is thought to prevent premature assembly and activity.

Infrared held in a pincer

Eurekalert - Jul 22 2021 - 00:07
Many applications, from fiber-optic telecommunications to biomedical imaging processes require substances that emit light in the near-infrared range (NIR). A research team in Switzerland has now developed the first chromium complex that emits light in the coveted, longer wavelength NIR-II range. In the journal Angewandte Chemie, the team has introduced the underlying concept: a drastic change in the electronic structure of the chromium caused by the specially tailored ligands that envelop it.

Scientists come up with new method for simultaneous processing of different types of waste

Eurekalert - Jul 22 2021 - 00:07
An international research team has come up with an innovative method for metal recovery from industrial waste. The new method allows the simultaneous recovery of multiple metals from waste oxides in a single process. This novel route will lower the burden on waste storage facilities with significant contributions to the economic and environmental sustainability of industrial waste management. The study was published in Journal of Environmental Management.

Defect engineering assisting in high-level anion doping towards fast charge transfer kinetic

Eurekalert - Jul 22 2021 - 00:07
Titanium dioxide, promising anode materials for sodium ion batteries, nonetheless, suffers from its inferior charge transfer kinetics owing to low diffusion coefficient and electronic conductivity, which will result in unsatisfactory high-rate capability. Here, an oxygen vacancy (OV) engineering assisted in high-content anion (S/Se/P) doping strategy to enhance its charge transfer kinetics for ultrafast sodium-storage performance is proposed to address these issues and expectative results have been obtained.
