The first questionnaire survey to identify possible separation-related problems in cats found 13.5 percent of all sampled cats displayed potential issues during their owner's absence, according to a study published April 15, 2020 in the open-access journal PLOS ONE by Daiana de Souza Machado, from the Universidade Federal de Juiz de Fora, Brazil, and colleagues.
DALLAS, April 15, 2020 -- Exposure to heavy smoke during recent California wildfires raised the risk of out-of-hospital cardiac arrests up to 70%, according to new research published today in the Journal of the American Heart Association, the open access journal of the American Heart Association.
NEW YORK -- Artificial sweeteners have never fully succeeded in impersonating sugar. Now, a Columbia study in mice has identified a brain mechanism that may explain why.
In an effort to investigate conditions found at the Earth's molten outer core, researchers successfully determined the density of liquid iron and sound propagation speed through it at extremely high pressures. They achieved this with use of a highly specialized diamond anvil which compresses samples, and sophisticated X-ray measurements. Their findings confirm the molten outer core is less dense than liquid iron and also put values on the discrepancy.
A multi-institutional collaboration, co-led by scientists at the University of Cambridge and Okinawa Institute of Science and Technology Graduate University (OIST), has discovered the source of efficiency-limiting defects in potential materials for next generation solar cells and flexible LEDs.
In the last decade, perovskites - a diverse range of materials with a specific crystal structure - have emerged as promising alternatives to silicon solar cells, as they are cheaper and greener to manufacture, whilst achieving a comparable level of efficiency.
Lancaster physicists working on the T2K major international experiment in Japan are closing in on the mystery of why there is so much matter in the Universe, and so little antimatter.
The Big Bang should have created equal amounts of matter and antimatter in the early Universe but instead the Universe is made of matter. One of the greatest challenges in physics is to determine what happened to the antimatter, or why we see an asymmetry between matter and antimatter.
In the last decade, perovskites - a diverse range of materials with a specific crystal structure - have emerged as promising alternatives to silicon solar cells, as they are cheaper and greener to manufacture, while achieving a comparable level of efficiency.
However, perovskites still show significant performance losses and instabilities, particularly in the specific materials that promise the highest ultimate efficiency. Most research to date has focused on ways to remove these losses, but their actual physical causes remain unknown.
A new study has found young people are leaving it 'too late' to seek help for eating disorders, citing fear of losing control over their eating or weight, denial, and failure to perceive the severity of the illness as reasons not to get professional advice.
The recent online survey of almost 300 Australian young adults aged 18-25 years found a majority had eating, weight or body shape concerns, and even those with anorexia or bulimia reportedly found reasons to delay getting treatment or expert interventions.
Like a parent of teenagers at a party, Mother Nature depends on chaperones to keep one of her charges, the immune system, in line so that it doesn't mistakenly attack normal cells, tissues and organs in our bodies. A recent study by Johns Hopkins Medicine researchers has demonstrated that in mice -- and probably humans as well -- one biological chaperone may play a key role in protection from such attacks, known as autoimmune responses, which are a hallmark of diseases such as multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus and type 1 diabetes.
Especially in times of shortage of skilled workers, some companies do not offer continuing education that improves the employees' chances on the labour market. Behind this restraint is the employer's fear that employees who have undergone extensive training will use their improved opportunities to switch to other companies.
An international team of researchers have found a new way to speed up quantum computing that could pave the way for huge leaps forward in computer processing power.
Scientists from the University of Nottingham and University of Stockholm have sped-up trapped ion quantum computing using a new experimental approach - trapped Rydberg ions; their results have just been published in Nature.
Parkinson's disease (PD) is a debilitating neurodegenerative disorder which is characterized by the degradation and subsequent loss in activity of the motor nerve system in the body. The disease is incurable and patients also tend exhibit non motor function disabilities as the disease progresses. Current treatment modalities often focus on improving the symptoms of PD after its onset.
When you pour a bowl of cereal, you probably aren't considering how humans came to enjoy milk in the first place. But animal milk was essential to east African herders at least 5,000 years ago, according to a new study that uncovers the consumption habits in what is now Kenya and Tanzania -- and sheds a light on human evolution.
We live in a world of matter - because matter overtook antimatter, though they were both created in equal amounts by the Big Bang when our universe began. As featured on the cover of Nature on 16 April 2020, neutrinos and the associated antimatter particles, antineutrinos, are reported to have a high likelihood of differing behaviour that offers a promising path to explaining the asymmetry between matter and antimatter. These observations may explain this mysterious antimatter disappearance.
Imagine a single garment that could adapt to changing weather conditions, keeping its wearer cool in the heat of midday but warm when an evening storm blows in. In addition to wearing it outdoors, such clothing could also be worn indoors, drastically reducing the need for air conditioning or heat. Now, researchers reporting in ACS Applied Materials & Interfaces have made a strong, comfortable fabric that heats and cools skin, with no energy input.
