Researchers have developed a robotic sensor that incorporates artificial intelligence techniques to read braille at speeds roughly double that of most human readers. The research team, from the University of Cambridge, used machine learning algorithms to teach a robotic sensor to quickly slide over lines of braille text. The robot was able to read the braille at 315 words per minute at close to 90% accuracy. Although the robot braille reader was not developed as an assistive technology, the researchers say the high sensitivity required to read braille makes it an ideal test in the development of robot ...

Overweight and obesity are contributing to rising death rates from bowel cancer among people aged 25-49 years in the European Union (EU) and the UK, although death rates from this type of cancer are decreasing overall across Europe.   These findings are from a new study published in the leading cancer journal Annals of Oncology [1] today (Monday), which predicts death rates from cancer in the EU and UK for 2024. It is the first time that an increase in bowel cancer death rates among young adults has been predicted for the EU, and it confirms a trend in the UK that the researchers first noted in 2021.   Researchers led by Carlo La Vecchia (MD), ...

Engaging in music throughout your life is associated with better brain health in older age, according to a new study published by experts at the University of Exeter. Scientists working on PROTECT, an online study open to people aged 40 and over, reviewed data from more than a thousand adults over the age of 40 to see the effect of playing a musical instrument – or singing in a choir - on brain health. Over 25000 people have signed up for the PROTECT study, which has been running for 10 years. The team reviewed participants’ musical experience and lifetime exposure ...

A study of pediatric heart surgery centers across the United States has demonstrated that, when it comes to successful surgery, it’s not just the size of the program that matters in determining quality outcomes. Historically, hospitals with a “low volume” of pediatric heart operations—in this case, those that perform 103 surgeries or fewer a year—have been associated with worse outcomes for patients. However, a team led by D. Chauhan, MD, from WVU Medicine Children’s ...

Despite national guidelines recommending surgical aortic valve replacement (SAVR) for patients under age 65 with severe aortic stenosis, many hospitals are still opting for a nonsurgical approach in patients under 60—possibly with poorer survival rates. In a study presented at The Society of Thoracic Surgeons’ 2024 Annual Meeting in San Antonio, Texas, researchers from the department of cardiac surgery in the Smidt Heart Institute at Cedars-Sinai in Los Angeles and the department of population health science and policy at Mount Sinai New York compared ...

The research, spanning from 2008 to 2019 and involving over one million patients undergoing isolated CABG with more than two bypass grafts, found that multi-arterial grafting CABG ...

Tokyo, Japan – Scientists from Tokyo Metropolitan University have been studying the strength and toughness of sand columns made of a mixture of sticky and non-sticky grains. They have uncovered the mechanism behind how the strength changes as grains are mixed in different ratios, and how a mixture can help keep the column more resilient to deformation. Non-sticky grains are also easily replaceable with other materials, enabling the design of stronger, tougher, functional matter.   Granular matter consists of vast numbers of small grains, like sand and powders. Such grains can be made to stick to each other, yielding strong materials ...

Recording the activity of large populations of single neurons in the brain over long periods of time is crucial to further our understanding of neural circuits, to enable novel medical device-based therapies and, in the future, for brain–computer interfaces requiring high-resolution electrophysiological information. But today there is a tradeoff between how much high-resolution information an implanted device can measure and how long it can maintain recording or stimulation performances. Rigid, silicon ...

Our sensory systems are highly adaptable. A person who cannot see after turning off a light in the night slowly achieves superior power to see even small objects. Women often attain a heightened sense of smell during pregnancy. How can the same sensory system that was underperforming can also exceed the expectation based on its prior performance? Since nature has perfected its sensory systems over evolutionary time scales, an interdisciplinary team of researchers in the McKelvey School of Engineering at Washington University in St. Louis tapped into ...

About 55 million people worldwide are living with dementia, according to the World Health Organization. The most common form is Alzheimer’s disease, an incurable condition that causes brain function to deteriorate. In addition to its physical effects, Alzheimer’s causes psychological, social and economic ramifications not only for the people living with the disease, but also for those who love and care for them. Because its symptoms worsen over time, it is important for both patients and their caregivers to prepare for the eventual need to ...

 The United States House of Representatives held more than 700 votes in 2023, but fewer than 30 bills were signed into law. Partisan politics may explain why, with polarization potentially causing enough friction to slow down the legislative process and make the passage of fewer, farther-reaching public laws likelier, according to researchers. The collaborators from Penn State and Colorado State University studied levels of polarization and patterns in the passage of budget bills and public laws from 1948 through ...

Scientists at La Jolla Institute for Immunology (LJI) have found direct evidence that exposure to common cold coronaviruses can train T cells to fight SARS-CoV-2. In fact, prior exposure to a common cold coronavirus appears to partially protect mice from lung damage during a subsequent SARS-CoV-2 infection. The new research, published recently in Nature Communications, provides an important first look at how "cross-reactive" T cells—which can fight multiple viruses from the same family—develop in an animal model. "We are learning how these immune cells develop ...

If life ever existed on Mars, the Perseverance rover’s verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the crater.   In new research published in the journal Science Advances, a team led by UCLA and The University of Oslo shows that at some point, the crater filled with water, depositing layers of sediments on the crater floor. The lake subsequently shrank and sediments carried by the river that fed it formed an enormous delta. As the lake dissipated over time, the sediments in the crater were eroded, forming ...
