Espresso coffee may prevent Alzheimer's symptoms, lab study finds

Compounds in espresso coffee may inhibit a process that is believed to be involved in the onset of Alzheimer's disease, according to early findings of a study conducted in lab. To make espresso coffee, hot water is forced through finely ground coffee beans, creating a concentrated extract. This is often used as a base for other drinks, including the trendy espresso martini. Recent research has suggested that coffee could also have beneficial effects against certain neurodegenerative diseases, including Alzheimer's disease. In healthy people, tau proteins help stabilise structures in the brain, but when certain diseases develop, the proteins can clump together into fibrils -- a process that is believed to be involved in the onset of Alzheimer's. The study, published in the Journal of Agricultural and Food Chemistry, nalaysed if compounds in espresso could prevent tau aggregation in vitro. Researchers from the University of Verona in Italy pulled espresso shots from store-bought bea

Climate change has shifted colour of over half of world's oceans: Study

The colour of over 56 per cent of the world's oceans, larger than Earth's total land expanse, has changed significantly over the last two decades and human-caused climate change is likely the driver, according to researchers. These colour changes, subtle to the human eye, cannot be explained by natural, year-to-year variability alone, the researchers from the Massachusetts Institute of Technology (MIT), US, and other institutes write in their paper published in the journal Nature. Ocean colour, a literal reflection of the life and materials in its waters, in regions near the equator was found to have steadily turned greener over time, indicating changes in the ecosystems within the surface oceans. The green colour of the ocean waters comes from the green pigment chlorophyll present in phytoplankton, the plant-like microbes abundant in upper ocean. Scientists are, therefore, keen to monitor phytoplankton to see their response to climate change. However, the authors of this study sho

Regular daytime naps linked to increased brain volume, reveals study

According to a new study conducted by academics at UCL and the University of the Republic in Uruguay, daytime napping may assist to protect brain function by slowing the speed at which our brains shrink as we age.The study, published in the journal Sleep Health, analysed data from people aged 40 to 69 and found a causal link between habitual napping and larger total brain volume - a marker of good brain health linked to a lower risk of dementia and other diseases.Senior author Dr Victoria Garfield (MRC Unit for Lifelong Health & Ageing at UCL) said: "Our findings suggest that, for some people, short daytime naps may be a part of the puzzle that could help preserve the health of the brain as we get older."Previous research has shown that napping has cognitive benefits, with people who have had a short nap performing better in cognitive tests in the hours afterwards than counterparts who did not nap.The new study aimed to establish if there was a causal relationship between ...

Easily spread virus exploits genomic weaknesses, causes cancer: Study

Researchers have described in a study how the Epstein-Barr virus (EBV), the ubiquitous virus easily spread through bodily fluids, not only exploits genomic weaknesses to cause cancer, but also reduces the body's ability to suppress it. The researchers at the University of California (UC) San Diego, US, said that more than 90 per cent of the world's population has been infected by the EBV, usually during childhood, and that while most of the infections it causes are mild and pass, the virus persists in the body, becoming latent or inactive, sometimes reactivating. The EBV spreads easily through bodily fluids, primarily saliva, through activities such kissing, sharing drinks or using the same eating utensils. The researchers' findings showed "how a virus can induce cleavage of human chromosome 11, initiating a cascade of genomic instability that can potentially activate a leukemia-causing oncogene and inactivate a major tumour suppressor," said senior study author Don Cleveland, ...

Over 10 million older adults in India likely have dementia: AI study

More than 10 million older adults aged 60 or over in India may have dementia, comparable to the prevalence rates for countries such as the US and the UK, according to a first-of-its-kind study. The research, published in the journal Neuroepidemiology, used an artificial intelligence (AI) technique known as semi-supervised machine learning to analyse data from 31,477 older adults. The international team of researchers found that the prevalence rate of dementia in adults aged 60 or over in India could be 8.44 per cent -- equating to 10.08 million older adults in the country. This compares to prevalence rates recorded in similar age groups of 8.8 per cent in the US, 9 per cent in the UK and between 8.5 and 9 per cent in Germany and France, they said. The prevalence of dementia was greater for those who were older, were females, received no education, and lived in rural areas, the researchers found. "Our research was based on the first and only nationally representative aging study in

Three million people in India at risk of flooding by glacial lakes: Study

Three million people in India are at risk of flooding caused by glacial lakes, the highest number of those exposed in the world, according to new study. The study by an international team led by scientists at UK's Newcastle University, UK is the first global assessment of areas at greatest risk of Glacial Lake Outburst Floods (GLOF). Published in the journal Nature Communications on Tuesday, it estimates that 15 million people around the world are at risk from flooding caused by glacial lakes. The researchers, which also identified priority areas for mitigation, said more than half the globally exposed populations are found in just four countries: India, Pakistan, Peru, and China. India and Pakistan contain the highest number of exposed people -- nearly three million and two million people respectively, or one-third of the global total combined -- while Iceland contains the least (260 people), they said. As the climate gets warmer, glaciers retreat and meltwater collects at the fr

Anti-inflammatory patterns explain fatigue in long Covid patients : Study

Researchers have detected an anti-inflammatory pattern in long Covid patients, which helps in understanding better what causes fatigue in patients with long term symptoms of the disease. The researchers at the University of Vienna, Austria, have now presented new evidence of triggers for fatigue following SARS-COV-2 infection. The team of researchers showed that an exaggerated anti-inflammatory response is likely to be responsible for long Covid syndrome (LCS). The study has been published in "iScience". Today, millions of people suffer from LCS, which significantly affects their quality of life. However, it is not easy to diagnose and treat due to a lack of understanding of the underlying disease mechanisms. The diagnosis and treatment of LCS is still very difficult, and there is only little knowledge about the factors causing accompanying symptoms. According to the study, the team of researchers, led by chemist Christopher Gerner, have now turned their attention to LCS using mass
