Just three minutes a day of moderate activity may be enough to boost better heart health in older adults, according to a study. Previous studies have shown that as people age, many do not engage in physical activity, increasing their chances of experiencing a cardiovascular event. In the new study, researchers from the UK and Australia noted that doing household chores or shopping for groceries -- referred to as incidental activities -- may also be enough to boost health. Incidental physical activity (IPA) encompasses activities of daily living outside the leisure-time domain and includes preparing meals, keeping the house clean, mowing the lawn, or gardening. “Any daily IPA amount of vigorous or moderate-intensity was associated with lower cardiovascular disease risk in a dose-response...

While eating chicken, known as lean meat, has long been considered healthier than red meat, a new study shows that regularly eating poultry may lead to early death due to gastrointestinal or digestive system cancers. The study, led by researchers at the National Institute of Gastroenterology, in Italy, is based on an analysis of health-related data for 4,869 adults living in Italy over 20-years. The findings showed that the risk of digestive system cancers including oesophageal, stomach, colon, pancreatic, and liver, is higher for men than for women. Poultry meat (mainly chicken) is currently among the most widely consumed meats worldwide. It is reasonably affordable and accessible, explaining the high global consumption rates. Prior research has suggested chicken as a protein source a...

A study has suggested that age 36 is when the ill-effects of having unhealthy habits as a young adult -- smoking, drinking and physical inactivity -- start becoming apparent. Researchers from the University of Jyvaskyla tracked about 370 residents of the Finnish city for over 30 years. Data was collected via surveys and medical tests at ages 27, 36, 42, 50 and 61. Three bad habits -- smoking, heavy drinking and a lack of exercise -- can lead to declines in health in people as young as 36, according to findings published in the journal Annals of Medicine. The team said that unhealthy behaviours in mid-life -- 40s and 50s -- are known to increase chances of developing health disorders in old age. However, their analysis showed that the ill-effects of unhealthy behaviours remained similar...

Imbalance in the digestive system may disrupt brain signals and influence behavioural symptoms in children with autism, according to a study on Monday.  Researchers from the University of Southern California (USC) demonstrated that gut metabolites impact the brain, and the brain, in turn, affects behaviour. The study, published in the journal Nature Communications, adds to a growing body of science implicating the “gut-brain” axis in autism. “The brain acts as the intermediary between gut health and autism-related behaviours,” said first author Lisa Aziz-Zadeh, professor at the Brain and Creativity Institute at the USC Dornsife College of Letters, Arts, and Sciences. “Previous studies highlighted differences in gut microbiomes and brain structures in autism, but our research connects t...

There has been a spike in male infertility cases, largely driven by increasing stress levels, obesity, poor lifestyle choices, and growing environmental pollution. These factors affect sperm quality, hormone balance, and overall reproductive health. This growing trend is a cause for concern, especially among couples aged 25-35 trying to conceive. Early diagnosis, maintaining a healthy weight, regular exercise, reducing stress, and avoiding smoking and alcohol can significantly help manage and improve male fertility. Every year, National Infertility Awareness Week is observed between April 20 and April 26. It is done to raise awareness about infertility and the need for more people to be educated about it. Infertility affects both men and women. Male infertility refers to problems in a man...

Outbreaks of vaccine-preventable diseases such as measles, meningitis, and yellow fever are on the rise globally amid misinformation and cuts to international aid, the United Nations and the Gavi vaccine alliance warned Wednesday. "Vaccines have saved more than 150 million lives over the past five decades," WHO chief Tedros Adhanom Ghebreyesus said in a statement. "Funding cuts to global health have put these hard-won gains in jeopardy." Tedros added that the increasing outbreaks around the world are "putting lives at risk and exposing countries to increased costs in treating diseases." Measles, for example, is making an "especially dangerous comeback," with cases rising every year since 2021 and reaching an estimated 10.3 million in 2023, which is a 20 percent increase since 2022. The...

By combining artificial intelligence (AI) with electrical recordings of brain activity, researchers have been able to track the language exchanged during conversations and the corresponding neural activity in different brain regions, according to a new study. The team from Department of Neurosurgery at Massachusetts General Hospital in the US investigated how our brains process language during real-life conversations. “Specifically, we wanted to understand which brain regions become active when we`re speaking and listening, and how these patterns relate to the specific words and context of the conversation,” said lead author Jing Cai in a paper published in Nature Communications. They employed AI to take a closer look at how our brains handle the back-and-forth of real conversations. Th...

Researchers from Tokyo Metropolitan University in Japan on Saturday said they have found that the motion of unlabelled cells can be used to tell whether they are cancerous or healthy.  They observed malignant fibrosarcoma cells and healthy fibroblasts on a dish and found that tracking and analysis of their paths can be used to differentiate them with up to 94 per cent accuracy. Beyond diagnosis, their technique may also shed light on cell motility related functions, like tissue healing, according to the study published in the journal PLOS One. The team of researchers, led by Professor Hiromi Miyoshi, came up with a way of tracking cells using phase-contrast microscopy, one of the most common ways of observing cells. Phase-contrast microscopy is entirely label free, allowing cells to mo...

A team of US scientists has found that a common pinworm medication may stop and reverse cancer growth in Merkel cell carcinoma, an aggressive form of skin cancer.  The research led by University of Arizona Cancer Center and published in the Journal of Clinical Investigation, found that in laboratory models of Merkel cell carcinoma, pyrvinium pamoate inhibited cancer cell growth and reversed the cancer’s neuroendocrine features. In mouse models of Merkel cell carcinoma, pyrvinium pamoate reduced tumour growth. Merkel cell carcinoma is a rare but fast-growing neuroendocrine cancer that is three to five times more likely than melanoma to be deadly. Response rates to current therapies – surgery, radiation and immunotherapy – are limited, resulting in a need for effective and broadly applica...

In a significant study, researchers have linked fatty and sugary diets to impaired cognitive function. The team from University of Sydney looked at the relationship between high-fat, high-sugar (HFHS) diets, particularly those high in refined sugar and saturated fat, and first-person spatial navigation. Spatial navigation is the ability to learn and remember a path from one location to another, a process that can approximate the health of the brain’s hippocampus, said the study published in the International Journal of Obesity. Dr Dominic Tran from the Faculty of Science’s School of Psychology led the research, which found HFHS diets have a detrimental effect on some aspects of cognitive function. It is likely those effects centre on the hippocampus, the brain structure important for s...
