Accuracy of AI in estimating best-corrected visual acuity from fundus photographs in eyes with diabetic macular edema

JAMA Ophthalmology

2023-06-08

(Press-News.org) About The Study: The results of this investigation suggest artificial intelligence (AI) can estimate best-corrected visual acuity directly from fundus photographs in patients with diabetic macular edema, without refraction or subjective visual acuity measurements, often within one to two lines on an Early Treatment Diabetic Retinopathy Study chart, supporting this AI concept if additional improvements in estimates can be achieved.

Scientists map complete genome of millet

2023-06-08

An international team of researchers has unlocked a large-scale genomic analysis of Setaria or foxtail millet, an important cereal crop. The study, led by researchers at the Chinese Academy of Agricultural Sciences and including scientists at NYU, advances our understanding of the domestication and evolution of foxtail millet, as well as the genetic basis for important agricultural traits. “Foxtail millet is considered to be the foundation for early Chinese civilization,” said Michael Purugganan, the ...

Improving market design for energy storage

2023-06-08

New York, NY—June 8, 2023—Energy storage plays a crucial role in our transition to cleaner and more sustainable energy sources. It enables us to store excess energy when it’s available, from renewable sources like wind and solar, and use it when demand is high or supply is limited. This helps stabilize the grid, reduces reliance on fossil fuels, and mitigates the impact of intermittent energy sources. Balancing consumer demands with power system capacities In many parts of the ...

DNA discovery highlights how we maintain healthy blood sugar levels after meals

2023-06-08

A study of the DNA of more than 55,000 people worldwide has shed light on how we maintain healthy blood sugar levels after we have eaten, with implications for our understanding of how the process goes wrong in type 2 diabetes. The findings, published today in Nature Genetics, could help inform future treatments of type 2 diabetes, which affects around 4 million people in the UK and over 460 million people worldwide. Several factors contribute to an increased risk of type 2 diabetes, such as older age, being overweight or having obesity, physical inactivity, and genetic predisposition. If untreated, type 2 diabetes can lead to complications, including eye and foot problems, ...

Confinement effects of carbon nanotubes on polyoxometalate clusters enhance electrochemical energy storage

2023-06-08

Carbon nanotubes (CNTs) are considered ideal electrochemical energy storage materials due to their high electrical conductivity, large theoretical surface area, and good chemical stability. However, CNTs tend to aggregate due to strong van der Waals forces, which reduces their electrochemically active area. This problem is even worse for single-walled carbon nanotubes (SWNTs) due to their high length-to-diameter ratio. Recently, a joint research team led by Dr. WANG Xiao from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese ...

When water temperatures change, the molecular motors of cephalopods do too

2023-06-08

Cephalopods are a large family of marine animals that includes octopuses, cuttlefish and squid. They live in every ocean, from warm, shallow tropical waters to near-freezing, abyssal depths. More remarkably, report two scientists at University of California San Diego in a new study, at least some cephalopods possess the ability to recode protein motors within cells to adapt “on the fly” to different water temperatures. Writing in the June 8, 2023 edition of Cell, first author Kavita J. Rangan, ...

A potential milestone in cancer therapy

2023-06-08

Prostate cancer is the most common non-skin cancer in men worldwide. According to international estimates about one in six men will get prostate cancer during their lifetime and worldwide, over 375’000 patients will die from it each year. Tumor resistance to current therapies plays an essential role in this and new approaches are therefore urgently needed. Now an international research team from the University of Bern, Inselspital Bern and the University of Connecticut (USA) has identified a previously unknown weak spot in prostate cancer ...

Comparing doctors to peers doesn’t make them hate their jobs and may improve quality of care, new USC Schaeffer study finds

2023-06-08

June 8, 2023 — Showing people how their behavior compares to their peers is a commonly used method to improve behavior. But in the wake of a global pandemic that exacerbated health care providers’ job dissatisfaction and burnout, questions remain about the potentially negative effects of peer comparison on the well-being of clinicians. A new study from the USC Schaeffer Center for Health Policy & Economics reveals fresh insights into the relationship between peer comparison and job satisfaction among clinicians. Published in JAMA Network Open, the study challenges prior findings that such feedback increases job dissatisfaction and burnout. Researchers ...

Scientists discover how plants fight major root disease

2023-06-08

Researchers led by CHEN Yuhang and ZHOU Jianmin from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences have shown how plants resist clubroot, a major root disease that threatens the productivity of Brassica crops such as rape. The study, which uncovers novel mechanisms underlying plant immunity and promises a new avenue for crop breeding, was published in Cell. Clubroot, a soil-borne disease, is the most devastating disease of Brassica crops. In China, approximately 3.2–4 million hm2 of agricultural land is affected by clubroot each year, resulting in a 20%–30% yield ...

The IL-17 protein plays a key role in skin ageing

2023-06-08

A team of researchers from IRB Barcelona and CNAG identifies the IL-17 protein as a determining factor in skin ageing. Blocking the function of IL-17 reduces the pro-inflammatory state and delays the appearance of age-related features in the skin. Published in the journal Nature Aging, the work opens up new perspectives in the development of therapies to improve skin ageing health. A team of scientists from the Institute for Research in Biomedicine (IRB Barcelona) in collaboration with the National ...

University of Cincinnati study examines role of metabolites in disease treatment

2023-06-08

Each year, about 200,000 people in the United States are diagnosed with a bulge in the lower part of the aorta, the main artery in the body, called an abdominal aortic aneurysm (AAA). New research from the University of Cincinnati examines the role a particular metabolite plays in the development of AAA and could lead to the first treatment of the condition. The research was published in the journal Circulation. “We started the study by examining whether AAA patients themselves had an increase in trimethylamine N-oxide (TMAO). We examined an American and Swedish ...
