Eye Drops May One Day Replace Reading Glasses, and Could Help Our Vision as we Age– www.discovermagazine.com

As we age, we’ll all experience a decline in our vision and will likely need reading glasses. Instead of reaching for those glasses though, imagine taking 2 to 3 eyedrops a day to see something up close.
New research that experts will present at the 43rd Congress of the European Society of Cataract and Refractive Surgeons (ESCRS) explores presbyopia, the condition that makes it hard for the eye to focus on close objects and text, and how eye drops could one day replace eyeglasses.
For this study, lead researcher Giovanna Benozzi, who is also the director of the Center for Advanced Research for Presbyopia in Buenos Aires, Argentina, and her team followed a group of 766 presbyopia patients with an average age of 55 years. The team’s hope was to help find an alternative solution to glasses and eye surgery.
“We conducted this research due to the significant unmet medical need in presbyopia management. Current solutions, such as reading glasses or surgical interventions, have limitations, including inconvenience, social discomfort, and potential risks or complications,” Benozzi said in a press release.
“There is a group of presbyopia patients who have limited options besides spectacles, and who are not candidates for surgery; these are our primary focus of interest,” Bennozi added in the press release.
New graphene oxide super-material is on the way to delivering next-generation supercapacitors, researchers say – Australian Manufacturing Forum

Excerpt:
Australian researchers have identified “a new kind of carbon-based material” allowing supercapacitors to store as much energy as lead-acid batteries while also performing better than conventional batteries at delivering power quickly.
According to a statement from the university on Tuesday, the results are “a major leap forward” for fast, powerful energy storage devices, and are now being commercialised by Ionic Industries.
The new material is named as multiscale reduced graphene oxide (M-rGO) and was created from naturally-occurring graphite. It is described as being made using a “rapid thermal annealing process” and featuring a “highly curved graphene structure with precise pathways for ions to move quickly and efficiently”.
The promising new material is detailed in a new paper in Nature Communications.
Monash’s Professor Mainak Majumder, who was part of the research team and heads the ARC Research Hub for Advanced Manufacturing with 2D Materials (AM2D), said that M-rGO made much more surface area available for storing energy, and which was unlocked by the method of heat treatment.

Against the backdrop of high market demand for effective anti-ageing cosmetics, a team of Chinese researchers assessed the clinical effectiveness of a 0.1 % pterostilbene-containing skincare emulsion against a control emulsion over 28 days with 31 participants.
The study employed a double-blind, split-face design, comparing the left and right sides of the face and using advanced instruments along with subject self-assessments. The set of instruments used, together with the findings, is reported in the team’s published article in the Journal of Dermatologic Science and Cosmetic Technology.
“Our results indicated that the pterostilbene emulsion remarkably improved skin elasticity, firmness, and reduced wrinkles, such as forehead, undereye, and Crow’s feet wrinkles, shares co-author Zhiyuan Chen, Founder of Guangzhou Luanying Cosmetics Co., Ltd. “It also increased the thickness of the epidermis layer, enhanced collagen and elastic fibers, and minimized skin pores.”
Compared to the control emulsion, the pterostilbene emulsion brought about statistically significant improvements, and all subjects expressed higher satisfaction with the pterostilbene emulsion. These results collectively demonstrated the superior anti-aging efficacy of the pterostilbene emulsion through multiple mechanisms.

To date, his lab at the Yale Microbial Sciences Institute has uncovered the evolutionary trick used by bacteria to breathe through tiny protein filaments, called nanowires, to dispose of excess electrons from the conversion of organic waste to electricity.
The adaptation has enabled bacteria to send electrons over distances 100-times their size through what the scholars refer to as bacterial “snorkeling.”
From its base on Yale’s West Campus, the lab’s previous work revealed the role and atomic structures of the nanowires, but to explain how the electrons were moving so fast, Malvankar found himself returning to where he began—the world of quantum theory.
“Biological theory just couldn’t explain their speed,” explained the associate professor of molecular biophysics and biochemistry. “Either our measurements were wrong, or we needed a new theory.”
UP student develops 3D bio-printing alternative to skin grafts – The Witness | Your compass in the community

Research by a University of Pretoria (UP) PhD graduate has led to the development of a skin replacement product that paves the way for 3D bioprinting of “natural” skin replacement products, offering an alternative to traditional skin grafts.
Dr Hafiza Parkar, a lecturer in UP’s Department of Pharmacology, received her PhD in Pharmacology during UP’s Spring Graduation season in the first week of September.
She said her research is particularly significant for treating secondary intention wounds, which are wounds left open to heal by themselves rather than being stitched together, such as ulcers and burns.
“Creating advanced dermal substitutes that replicate human skin offers a promising solution for treating secondary intention wounds,” Parkar said.
Alzheimer’s breakthrough: Simple blood test hailed as ‘game-changer’ for diagnosis – Kursiv Media

A clinical trial in the U.K. is evaluating a new blood test that could reshape how Alzheimer’s disease is diagnosed, according to The National.
Participants showing early signs of dementia are being recruited through NHS memory clinics to evaluate the test’s effectiveness. Researchers expect to have conclusive results within the next three years.
The project, led by University College London, focuses on whether measuring levels of the protein p-tau217 in blood samples can lead to faster and more accurate detection of Alzheimer’s disease. Early studies indicate that the test can identify individuals with cognitive decline with about 80 percent accuracy as being likely to have the disease.
First identified in 1906 by German physician Alois Alzheimer, Alzheimer’s disease is the leading cause of dementia in older adults and is marked by a progressive decline in cognitive abilities.
Alzheimer’s is associated with the accumulation of amyloid and tau proteins in the brain. P-tau217 is considered a particularly strong biomarker because it signals the presence of both.
