A new artificial intelligence system called a semantic decoder can translate a person’s brain activity — while listening to a story or silently imagining telling a story — into a continuous stream of text. The system developed by researchers at The University of Texas at Austin might help people who are mentally conscious yet unable to physically speak, such as those debilitated by strokes, to communicate intelligibly again. The study, published in the journal Nature Neuroscience, was led by Jerry Tang, a doctoral student in computer science, and Alex Huth, an assistant professor of neuroscience and computer science at UT Austin. The work relies in part on a transformer ...

In 2010 Prof. Shlomo Havlin and collaborators published an article in the journal Nature proposing that the abrupt electricity failure causing the famous 2003 Italy blackout was a consequence of the inter-dependency of two networks. According to Havlin's theory the dependency between the power network and its communication system led to cascading failures and abrupt collapse. Havlin's seminal work ignited a new field in statistical physics known as “network of networks” or "interdependent networks" and paved the way for understanding and predicting the effects of the ...

An unusually well-preserved "Marine Dwarf World" from 462 million years ago was found at Castle Bank, Wales by a team led by the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS).

Among them are Jonathan Rothberg, who pioneered the next-generation of human DNA sequencing, enabling low-cost decoding of human and other living organisms’ genomes; and Daniel Joseph, whose advances in special effects and illusion at Disney Imagineering have revolutionized the theme park experience ...

Efforts to combat climate change have contributed to the rise of renewable energy production through solar panels, windmills, and other technologies. Because of this, consumers have now become “prosumers,” capable of producing their own electricity. While the prosumers’ use of distributed renewable energy increases the energy sector’s resilience, their decreased reliance on the bulk electricity market has led to new and unintended consequences. It is anticipated that these avenues will push traditional consumers to become prosumers, making it difficult to recover lumpsum infrastructure investments ...

Magnesium diboride (MgB2), a binary compound, behaves as a superconductor – a substance that offers no resistance to electric current flowing through it – at a moderate temperature of around 39 K (-234°C). This temperature can be achieved using relatively inexpensive liquid hydrogen or neon coolants. In addition, MgB2 is inexpensive, lightweight, and non-toxic, and its precursors – magnesium (Mg) and boron (B) – are abundantly available. As a result, it can replace conventional low-temperature ...

At the end of 2022, the federal government eliminated the “X waiver,” a major hurdle to providing addiction treatment, but progress needs to be continued, according to the authors of a new Perspective piece published in the New England Journal of Medicine. The X waiver required a special license and uncompensated training for physicians and other prescribers, creating a regulatory barrier to offering lifesaving buprenorphine treatment for opioid use disorder. Ending the X, the authors write, is necessary but not sufficient to achieve overdose-prevention goals. Sarah Wakeman, MD, Medical Director for Substance Use Disorder at Mass General Brigham, and her co-author ...

CHAMPAIGN, Ill. — The mechanics behind the collapse of soft materials structure have befuddled researchers for decades.

Photonic chips have revolutionized data-heavy technologies. On their own or in concert with traditional electronic circuits, these laser-powered devices send and process information at the speed of light, making them a promising solution for artificial intelligence’s data-hungry applications. In addition to their incomparable speed, photonic circuits use significantly less energy than electronic ones. Electrons move relatively slowly through hardware, colliding with other particles and generating heat, while photons flow without losing energy, ...

INDIANAPOLIS – A new study conducted by researchers from Regenstrief Institute and the universities of South Carolina and Indiana has found that the most commonly prescribed blood pressure medications, taken for at least six months prior to an intensive care unit (ICU) admission, did not protect against developing delirium in the ICU, regardless of patient age, gender, race, co-morbidities or insurance status. Delirium, an acute brain failure, affects approximately seven million hospitalized patients in the U.S. annually and is associated with longer hospital and ICU length of stay, higher likelihood ...

[LOS ANGELES (May 1, 2023) — While Wilms tumor—also known as nephroblastoma-- is rare, it is the most prevalent childhood kidney cancer. Researchers at Children’s Hospital Los Angeles have now pinpointed a disruption in early kidney progenitor cell development that can be linked to the formation of Wilms tumor. In a study published in Advanced Science, researchers at the GOFARR Laboratory in Urology compared kidney progenitor cells from a tumor with precursor cells from a healthy kidney. Normally, these precursor cells mature into kidney cells, but when their early development is dysregulated, they behave like cancer stem cells. While most children ...

Researchers, including from NTNU, are breeding bacteria-free fish fry. This pursuit is more important than you might think. “We’re managing to keep the fry bacteria-free for up to 12 weeks after the eggs hatch,” says Ingrid Bakke. She is a professor at NTNU’s Department of Biotechnology and Food Science. This step has now helped researchers on the trail to figuring out how bacteria and fish affect each other. Understanding their interaction could one day also lead to a method ...

Acute kidney injury (AKI) is a clinical syndrome characterized by a decrease in kidney function. AKI is very common in the United States' Medicare population, particularly among hospital intensive care unit (ICU) admissions. Furthermore, AKI is associated with the incidence of end-stage renal disease, which eventually increases the burden of long-term care, higher health-care costs, and increased mortality. In several instances, kidney diseases have been linked to air pollution exposure. Inhaling air pollutants, including gases like nitrogen dioxide (NO2), ozone (O3), and fine particulate matter (PM2.5) that remains suspended in ...

Statement Highlights: More than half of people who survive a stroke develop cognitive impairment within the first year after their stroke, and as many as 1 in 3 may develop dementia within 5 years. The high risk of cognitive impairment and dementia after a stroke suggests early screening is essential for determining initial treatment, such as multidisciplinary care, cognitive rehabilitation or increased physical activity. It’s also important to assess stroke survivors for cognitive changes over time to offer appropriate treatment modifications and support for longer-term care. Cognitive impairment after stroke may fluctuate, particularly ...

Different market products give very different results when it comes to liberating the antioxidant lutein from spinach in smoothies. Researchers at Linköping University, Sweden, have examined 14 common dairy and plant-based products and found that only four of these increased lutein liberation. Compared to water, some drinks had a negative effect on the lutein content in spinach smoothies.   Most people know that spinach is good for your health. One substance found in, for instance, spinach and kale is lutein. Several experimental studies have shown that lutein can suppress processes linked to inflammation, and there is now ample research indicating ...

It’s generally accepted we will lose muscle strength and slow down as we age, making it more difficult to perform simple tasks such as getting up, walking and sitting down.   But new Edith Cowan University (ECU) research indicates this could also be a signal for another sinister health concern of ageing: late-life dementia.   To investigate the relationship between muscle function and dementia, the research teams from ECU’s Nutrition & Health Innovation Research Institute and Centre for Precision Health used data from the Perth Longitudinal Study of Ageing in Women to examine more than 1000 women with an average age of 75.   In collaboration with the ...

Does air pollution affect your heart? Acute exposure to air pollution was found to be associated with an increased risk of arrythmia — irregular heartbeat — in a large study of 322 Chinese cities published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.220929. The common arrhythmia conditions atrial fibrillation and atrial flutter, which can progress to more serious heart disease, affect an estimated 59.7 million people globally. Air pollution is a modifiable risk factor for heart disease, but the evidence linking it with ...

The United States is in the midst of a mental health crisis with rising rates of hospitalization for suicide and self-harm events among children and adolescents. A study, “Characteristics Associated with Serious Self-Harm Events in Children and Adolescents,” set to be published in the June issue of Pediatrics, looked at how best to determine which children are at elevated risk for self-harm. Researchers identified four separate profiles to help medical professionals better assess children at elevated ...

The way our senses adjust while playing high-intensity virtual reality games plays a critical role in understanding why some people experience severe cybersickness and others don’t. Cybersickness is a form of motion sickness that occurs from exposure to immersive VR and augmented reality applications. A new study, led by researchers at the University of Waterloo, found that the subjective visual vertical – a measure of how individuals perceive the orientation of vertical lines – shifted considerably after participants played a high-intensity ...

In the race to make the world more livable for people and nature, progress on land outpaced successes in the seas, raising red flags that wealthier countries’ advantages may be upsetting a balance, a Michigan State University study shows. Progress in oceans actually slowed after the United Nations member states adopted the 17 Sustainable Development Goals in 2015. That action aims to facilitate global partnerships among developed and developing countries in sustainable development. So far, though, a new study in the open-access journal iScience reveals evidence that ...
