Our cells are surrounded by a fragile membrane that’s only 5 nanometers thick, 1/20 of a soap bubble. Cells are easily damaged by physiological activities, including muscle contraction and tissue injury. To cope with such damage, cells are equipped with mechanisms that can repair membrane damage to a certain degree. Mechanical damage to the cell membrane was previously believed to trigger two simple cellular outcomes: recovery or death. In this study, however, the researchers uncovered a third outcome – cellular senescence.  “When I started this project, I simply aimed to understand ...

Australia can lay claim to two new species of native rodent thanks to a study from The Australian National University (ANU).  The aptly named delicate mouse was previously thought to be a single species spanning a massive stretch of the country from the Pilbara in Western Australia, across parts of the Northern Territory and through Queensland down to the New South Wales border.   But researchers at ANU and CSIRO thought there might be more to the story.   Lead author Dr Emily Roycroft, from ANU, said we now know there ...

Today, a team of scientists from Trinity College Dublin and investigators from FutureNeuro announced a major discovery that has profound importance for our understanding of brain fog and cognitive decline seen in some patients with Long COVID. In the months after the emergence of the novel coronavirus SARS-CoV2 in late 2019 a patient-reported syndrome termed Long-COVID began to come to the fore as an enduring manifestation of acute infection.    Long COVID has up to 200 reported symptoms to date, but in general patients report lingering symptoms such as fatigue, ...

The annual rate of carbon emissions due to the degradation of carbon stocks in mangrove forests is predicted to rise by nearly 50,000% by the end of the century, according to a new study published in IOP Publishing’s journal Environmental Research Letters. Mangroves in regions such as southern India, southeastern China, Singapore and eastern Australia are particularly affected.   Mangrove forests store a large amount of carbon, particularly in their soils, however human development in these areas has led to the degradation of these carbon ...

Scientists at the University of Zurich have developed an innovative neural cell culture model, shedding light on the intricate mechanisms underlying neurodegeneration. Their research pinpointed a misbehaving protein as a promising therapeutic target in the treatment of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neurodegenerative diseases cause some of the neurons in our brains to die, resulting in different symptoms depending on the brain region affected. In amyotrophic lateral sclerosis (ALS), neurons in the motor cortex and spinal ...

A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event’s magnitude. As a result, the Kobe University research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far. In addition to lava, volcanos eject large amounts of pumice, ashes and gases as a fast-moving flow, known as “pyroclastic flow,” and its sediments are a valuable data source on past eruptions. For volcanoes on land, geologists understand the sedimentation mechanism of pyroclastic flows well, but the sediments themselves get lost easily ...

Imagine doubling the processing power of your smartphone, tablet, personal computer, or server using the existing hardware already in these devices.  Hung-Wei Tseng, a UC Riverside associate professor of electrical and computer engineering, has laid out a paradigm shift in computer architecture to do just that in a recent paper titled, “Simultaneous and Heterogeneous Multithreading.”  Tseng explained that today’s computer devices increasingly have graphics processing units (GPUs), hardware accelerators for artificial intelligence (AI) and machine learning (ML), or digital signal processing units as essential components. These components ...

Home health care use in the last three years of a patient’s life is associated with a higher likelihood of hospice care at the end of life, according to a Rutgers Health study.   Researchers, whose findings are published in the Journal of Palliative Medicine, examined the home health care and hospice care experiences of more than 2 million people.   “In addition to benefits for the patient, hospice care also provides resources and support to help family caregivers cope with the physical, emotional and practical challenges of caring for a loved one at the end of life,” said Olga Jarrín, senior author of the ...

For the first time researchers have identified patterns of risk for several different types of cancer in men with fertility problems and their families.   The study, which is published today (Thursday) in Human Reproduction [1], one of the world’s leading reproductive medicine journals, found that families of men who have very few or no sperm in their semen have a higher risk of developing cancer, including developing cancer at younger ages, compared to families of fertile men.   The risk and the type of cancer varied greatly depending on whether the men had low numbers of sperm (oligozoospermic) or none (azoospermic), with several cancers identified ...

1. Background Many proteins within the body form complexes with other proteins, determining the fate of cells. Therefore, the analysis of protein-protein interactions (PPI) is a crucial process for understanding the biological function of target proteins. Membrane proteins, which account for over 30% of human genes, play a vital role in cell functions. Many membrane proteins are known to form complexes to exert their functions, making the elucidation of membrane protein PPIs essential for understanding protein function. However, the development of technologies to analyze PPIs, especially extracellular protein–protein interactions (exPPIs) of living cells, has ...

PHILADELPHIA—(Feb. 21, 2024)—The Wistar Institute’s associate professor Mohamed Abdel-Mohsen, Ph.D., has demonstrated, with his lab and collaborators, a connection between viral damage to the gut and premature biological aging. The group found that this pro-aging connection can contribute to both gut permeability and premature systemic & intestinal tissue aging in people living with chronic HIV infection, and their discovery is detailed in the newly published paper titled, “Distinct Intestinal Microbial Signatures Linked to Accelerated Systemic and Intestinal Biological Aging,” published in the journal Microbiome. When people's bodies age faster ...

Key points: Chronic exposure to fine particulate air pollutants (PM2.5) may increase seniors’ risk of cardiovascular hospitalization, with disproportionate impacts on residents of socioeconomically deprived neighborhoods. The findings suggest that to protect heart health, there is no safe threshold for chronic PM2.5 exposure, and that the EPA’s newly updated standard for the U.S.’s annual average PM2.5 level isn’t low enough to reduce the burden of cardiovascular disease or protect public health overall. Boston, MA—Chronic exposure to fine particulate air pollutants ...

A UCL-developed app that provides speech therapy for people with the language disorder aphasia has been found to significantly improve their ability to talk. iTalkBetter, developed by the Neurotherapeutics Group at the UCL Queen Square Institute of Neurology, provides users the digital platform to practice over 200 commonly used words, in their own time and without any limits on the amount of therapy they receive. While employing games to maintain engagement, the app’s integrated speech recogniser analyses speech in real time to give the user feedback on whether they have named the displayed item correctly. A new study, published in eClinicalMedicine, ...

Using intravascular imaging to guide stent implantation during percutaneous coronary intervention (PCI) in heart disease patients significantly improves survival and reduces adverse cardiovascular events compared to angiography-guided PCI alone, the most commonly used method. These are the results from the largest and most comprehensive clinical study of its kind comparing two types of intravascular imaging methods (intravascular ultrasound, or IVUS, and optical coherence tomography, or OCT) with angiography-guided PCI. The study, published Wednesday, February 21, in The Lancet, is the first to show that these two methods of ...

Short and long term exposure to fine particulate matter (PM2.5) air pollution is linked to an increased risk of hospital admission for major heart and lung diseases, find two large US studies, published by The BMJ today. Together, the results suggest that no safe threshold exists for heart and lung health. According to the Global Burden of Disease study, exposure to PM2.5 accounts for an estimated 7.6% of total global mortality and 4.2% of global disability adjusted life years (a measure of years lived in good health). In light of this extensive evidence, the World Health Organization ...

Children born in October are both more likely to be vaccinated against influenza and least likely to be diagnosed with influenza compared with children born in other months, finds a US study published by The BMJ today. The results suggest that birth month is associated with both timing of flu vaccination and the likelihood of a flu diagnosis - and that October is the optimal time for young children to have a flu shot, in line with current recommendations. Annual influenza vaccination is particularly important for young children, who are at higher risk of flu and severe ...

UNDER EMBARGO UNTIL 6:30 PM EST, Feb. 21, 2024 A UCLA Health-led study found a combination of interventions of one-on-one telehealth coaching, peer support forums, and automated text messages more than doubled the use of the HIV prevention strategy, called PrEP, among younger, at-risk Americans, a group that historically has had low use of the medication. The randomized controlled trial results, published in the journal Lancet Digital Health, tested combinations of interventions to improve HIV prevention behaviors, including pre-exposure prophylaxis, or PrEP, among younger Americans who have historically ...

Seaports act as hubs for the global spread of MtrBTN2,1 a rare contagious cancer affecting mussels. In this disease, cancer cells can be transmitted, like parasites, from one mussel to another nearby. While, in nature, such contagion mainly occurs between mussels in the same bed, ports and maritime transport facilitate the spread of MtrBTN2 to other locations, through biofouling, whereby diseased mussels attach themselves to ship hulls. This finding, the fruit of research by a team led by scientists from the CNRS and the University of Montpellier,2 will be published in Proceedings of the Royal Society B ...
