Over the last four decades, warming climate and ocean temperatures have rapidly altered the Greenland Ice Sheet, creating concern for marine ecosystems and weather patterns worldwide. The environment has challenged scientists in their attempts to measure how water moves around and melts the ice sheet because equipment can be destroyed by icebergs floating near the glaciers. Collected using a novel approach, research from the University of Maine has unearthed new information to help scientists better understand circulation patterns of ocean water around glaciers. A group of pioneers in glacial research attached GPS devices to icebergs and used their mobility to understand fjord circulation, ...

COLUMBUS, Ohio – Putting off a burdensome task may seem like a universal trait, but new research suggests that people whose negative attitudes tend to dictate their behavior in a range of situations are more likely to delay tackling the task at hand. The psychological term to describe this mental process is called valence weighting bias, which describes people’s tendency to adapt in new circumstances by drawing more strongly from either their positive or negative attitudes – or, in the context of approaching an unpleasant task, whether negative or positive internal “signals” carry the most weight in guiding the final behavior.   “And ...

Suppose two speakers of the same language are playing a guessing game where each has the same color swatches, and Player 1 tries to get Player 2 to guess a hue by naming the color. If the second player consistently guesses correctly as often as possible, that indicates their language has an efficient color naming system. Past research has shown that efficient color vocabularies are constrained both by how people perceive colors and by how much they want or need to communicate about a given color. For example, Penn researchers found in a 2021 study that the need to communicate about reds and yellows is high across languages, while greens are more important in some languages. Now, ...

Score another one for artificial intelligence. In a recent study, 151 human participants were pitted against ChatGPT-4 in three tests designed to measure divergent thinking, which is considered to be an indicator of creative thought. Divergent thinking is characterized by the ability to generate a unique solution to a question that does not have one expected solution, such as “What is the best way to avoid talking about politics with my parents?” In the study, GPT-4 provided more original and elaborate answers than the human participants. The study, “The current state of artificial intelligence generative ...

Researchers from Tokyo Medical and Dental University (TMDU) find that the cells that make up aldosterone-producing adenomas become more transcriptionally active and express higher levels of genes linked to hormone production over intratumoral differentiation.   Tokyo, Japan – There is strength in teamwork, and it turns out that this applies to tumors, too. Researchers from Japan have reported that different types of cells within a single benign tumor may work together to promote the tumor’s growth.   In a study published this ...

Older drivers who have worse spatial orientation ability experience greater difficulty when making turns across oncoming traffic, according to new research from the University of East Anglia (UEA).  Spatial orientation skills are the combination of skills that enable us to mentally determine our position, or the position of our vehicle and other vehicles, relative to the environment.  Lead author Sol Morrissey, a PhD researcher at UEA’s Norwich Medical School, said: “Driving safety is typically reduced in older adults due to changes that take place during ...

Crown ethers were discovered in 1967. They were then modified by adding a metal-containing unit creating metallacrown ethers. These metallacrown ethers have been the subject of intensive research. Depending on the molecular makeup of the metallacrown ethers and their resultant architecture, the properties and therefore the uses of the metallacrowns can change. They have many different uses currently, and ongoing studies continue to expand their application. Just a few of these include magnetic refrigeration, imaging agents—specifically as potential contrast agents in magnetic resonance imaging—and single-molecular ...

The ongoing COVID-19 pandemic caused by SARS-CoV-2 has caused serious damage to public health and the global economy, and one strategy to combat COVID-19 has been the development of broadly neutralizing antibodies for prophylactic and therapeutic use. The most emergency-use authorized (EUA) therapeutic monoclonal antibodies, are more likely to lose their neutralizing activities as the viral epitopes (e.g. the receptor-binding domain, RBD) within spike protein of SARS-CoV-2 they target are more prone to mutate. By contrast, the S2 subunit of spike protein, has a much lower frequency of mutation than ...

Researchers have discovered how “leaky” mitochondria – the powerhouses of our cells – can drive harmful inflammation responsible for diseases such as lupus and rheumatoid arthritis. Scientists may be able to leverage the findings to develop better treatments for those diseases, improve our ability to fight off viruses and even slow aging. The new discovery reveals how genetic material can escape from our cellular batteries, known as mitochondria, and prompt the body to launch a damaging immune response. By developing therapies to target this process, doctors may one day be able to stop the harmful inflammation ...

The new research paper, published on Nov. 30 in the journal Cyborg and Bionic Systems, indicated the participants in the intervention group had higher activity levels after THR, compared to those in the control group. The Cohen’s effect ...

Zinc-air batteries are an inexpensive, powerful battery alternative that can be used on the small scale to power electronics or on the large scale for electric vehicles or energy storage. These batteries work when oxygen from the air oxidizes zinc, but the difficulty in oxygen activation which degrades battery performance has prevented their wide commercial adoption. Information presented in a paper published in Carbon Future on 19 January shows how fullerene- metalloporphyrin derived carbon materials as catalysts can improve the performance and stability of zinc-air batteries. “The sluggish kinetic characteristics caused by the difficulty ...

Highlights: A chemical called Bisphenol A (BPA) is used to make many durable plastics and resins. Previous studies suggest high BPA exposure can increase health risks and change gut microbiome structure. Researchers investigated links between BPA exposure, obesity and the gut microbiome. The study found that normal-weight children had more unique bacteria taxa, which may help degrade BPA. The findings may help point to microbial strains that neutralize BPA in the gut. Washington, D.C. — March 1, 2024 — A synthetic chemical called Bisphenol A, or BPA, is widely used in the production of durable plastic products including eyewear, ...
