The World Health Organization (WHO) has sounded the alarm on the long-term health repercussions of the COVID-19 pandemic in its newly released World Health Statistics Report 2025. The report reveals a staggering decline in global life expectancy, which dropped by 1.8 years between 2019 and 2021 – the sharpest fall in recent history, effectively reversing [...]
How are we able to recall a word we want to say? This basic ability, called word retrieval, is often compromised in patients with brain damage. Interestingly, many patients who can name words they see, like identifying a pet in the room as a "cat", struggle with retrieving words in everyday discourse. Scientists have [...]
Melting sea ice changes not only how much light enters the ocean, but also its color, disrupting marine photosynthesis and altering Arctic ecosystems in subtle but profound ways. As global warming causes sea ice in the polar regions to melt, it is not just the amount of sunlight entering the ocean that changes. The color of [...]
A new study reveals that biofilms in washing machines may contain potential pathogens and antibiotic resistance genes, posing possible risks for laundering healthcare workers’ uniforms at home. Washing healthcare uniforms at home could be inadvertently aiding the spread of antibiotic-resistant infections within hospitals, according to new research led by Katie Laird of De Montfort [...]
Researchers found the PHGDH gene directly causes Alzheimer’s and discovered a drug-like molecule, NCT-503, that may help treat the disease early by targeting the gene’s hidden function. A recent study has revealed that a gene previously identified as a biomarker for Alzheimer’s disease is not just a marker, it is a direct cause of the disease. [...]
Introduction The human brain contains nearly 86 billion neurons, constantly exchanging messages like an immense social media network, but neurons do not work alone – glial cells, neurotransmitters, receptors, and other molecules form a vast communication web that governs everything from thought to behavior. Inside each neuron, electrical impulses travel rapidly, while communication between neurons [...]
A landmark study by scientists at the University of Oxford, has unveiled crucial insights into the way that COVID-19 vaccines mitigate severe illness in those who have been vaccinated. Despite the global success of COVID-19 vaccination campaigns, concerns remain around the continued spread of this disease including in vaccinated individuals. For this reason, researchers [...]
A single blood test, designed to pick up chemical signals indicative of the presence of many different types of cancer, could potentially thwart progression to advanced disease while the malignancy is still at an early stage and amenable to treatment in up to half of cases, suggests a modelling study published in the open access [...]
Lining the shelves of American supermarkets are food products with chemicals linked to health concerns. To a great extent, the FDA allows food companies to determine for themselves whether their ingredients and additives are safe. Companies don't have to tell the FDA about those decisions, and they don't have to list all ingredients on [...]
The number of lives lost around the world due to infections that are resistant to the medications intended to treat them could increase nearly 70% by 2050, a new study projects, further showing the burden of theongoing superbug crisis. Cumulatively, from 2025 to 2050, the world could see more than 39 million deaths that [...]
