Pet ownership, living alone, and cognitive decline among adults age 50 and older

JAMA Network Open

2023-12-26
(Press-News.org) About The Study: Pet ownership was associated with slower rates of decline in verbal memory and verbal fluency among older adults living alone, but not among those living with others in this study of 7,900 participants age 50 and older. Pet ownership offset the associations between living alone and declining rates in verbal memory and verbal fluency. Further studies are needed to assess whether pet ownership slows the rate of cognitive decline in older adults living alone. 

Authors: Ciyong Lu, Ph.D., of Sun Yat-sen University in Guangzhou, China, is the corresponding author.

Scientists use organoid model to identify potential new pancreatic cancer treatment

Scientists use organoid model to identify potential new pancreatic cancer treatment
2023-12-26
A drug screening system that models cancers using lab-grown tissues called organoids has helped uncover a promising target for future pancreatic cancer treatments, according to a new study from researchers at Weill Cornell Medicine. In the study, published Dec. 26 in Cell Stem Cell, the scientists tested more than 6,000 compounds on their pancreatic tumor organoids, which contain a common pancreatic cancer-driving mutation. They identified one compound—an existing heart drug called perhexiline maleate—that powerfully suppresses ...

Risk of young-onset dementia could be reduced through targeting health and lifestyle factors - study

2023-12-26
December 21 Peer reviewed /observational study / in people* Strictly embargoed 4PM UK time on Tuesday December 26 Researchers have identified a wide range of risk factors for young-onset dementia. The findings challenge the notion that genetics are the sole cause of the condition, laying the groundwork for new prevention strategies. The largescale study identified 15 risk factors, which are similar to those for late-onset dementia. For the first time, they indicate that it may be possible to reduce the risk of young-onset dementia ...

They published their work on Dec. 20 in Energy Material Advances.   "Economic, efficient, and safe hydrogen storage methods play a crucial role in exploiting hydrogen energy, reducing carbon emissions, and improving the utilization efficiency of renewable clean energies," said paper author Jianxin Zou, professor in National Engineering Research Center of Light Alloys Net Forming & State Key Laboratory of Metal Matrix Composites. "Solid-state hydrogen storage in hydrides has been considered as a promising hydrogen storage technology. Although the industrial ...

Artificial intelligence predicts the influence of microplastics on soil properties

Artificial intelligence predicts the influence of microplastics on soil properties
2023-12-26
Plastic waste and its buildup in nature has become a major environmental concern in recent times. While plastic pollution in the oceans is undoubtedly a concern, the presence of plastics in soils around the world is also known to cause severe environmental and health issues. As plastics fragment into smaller pieces known as microplastics (MPs) in the soil through natural and anthropogenic processes, they drastically alter soil properties. Moreover, they are also absorbed by plants, potentially entering human ...

Electronic “soil” enhances crop growth

Electronic “soil” enhances crop growth
2023-12-25
Barley seedlings grow on average 50% more when their root system is stimulated electrically through a new cultivation substrate. In a study published in the journal PNAS, researchers from Linköping University have developed an electrically conductive “soil” for soilless cultivation, known as hydroponics.  “The world population is increasing, and we also have climate change. So it’s clear that we won’t be able to cover the food demands of the planet with only the already existing agricultural methods. But with hydroponics we can grow food also in ...

Unraveling the mystery of hereditary diffuse gastric cancer

Unraveling the mystery of hereditary diffuse gastric cancer
2023-12-25
Gastric cancer, a significant global health burden, claims over 7% of cancer-related deaths annually. Although only 1-3% of cases have a genetic basis, understanding these genetic drivers is crucial for developing preventative strategies. Gastric cancer, a formidable foe in the global health arena, casts a long shadow over millions of lives each year. While its tendrils reach far and wide, a distinct subset – hereditary diffuse gastric cancer (HDGC) – emerges as a particularly aggressive and enigmatic adversary. This group of cancers, accounting for roughly 10% ...

Power of illusion can help with learning new movements

Power of illusion can help with learning new movements
2023-12-23
Tokyo, Japan – Researchers from Tokyo Metropolitan University showed that visual aids which create the illusion of movement, like a screen placed in front of one’s hand showing the hand move, can improve motor performance and the early stages of motor learning. Compared to observing third-person motions, functional near-infrared spectroscopy data also showed greater changes in brain activity in regions associated with motor learning. Findings like this might inform new treatment strategies for hemiplegic stroke patients. Visual-motor illusion (VMI) is the curious illusion of watching your body move even while it is still. ...

Live Christmas trees affect indoor air chemistry, NIST researchers find

Live Christmas trees affect indoor air chemistry, NIST researchers find
2023-12-22
Every holiday season, Americans buy nearly 30 million live Christmas trees. Many families enjoy not only having a live tree inside their homes but also smelling the fresh fragrance it creates. That smell comes from chemicals called volatile organic compounds (VOCs). However, little is known about how much is emitted and whether they have any health impacts. “Our nose is a good chemical sensor,” said Dustin Poppendieck, an environmental engineer at the National Institute of Standards and Technology (NIST). “We know that these trees are emitting something, ...

Evolution of tuberculosis – in new light

Evolution of tuberculosis – in new light
2023-12-22
Recent research suggests that the emergence of tuberculosis infection in human populations dates back tens of thousands of years earlier than previously known cases in the Middle East. In collaboration with an international research team, Hungarian researchers have edited and published a special issue of the journal Tuberculosis. In July 2022, the Department of Anthropology of the University of Szeged organised a conference on the paleopathology and evolution of tuberculosis. The ICEPT3 conference was closely linked to the NRDI-best funded research project of György ...
