Ultrasound (US) imaging is a widely employed diagnostic tool used for real-time imaging of various organs and tissues using ultrasonic sound waves. The waves are sent into the body, and images are created based on how the waves reflect off internal tissues and organs. It is used for guiding many medical procedures, including biopsies and injections, and is important for dynamic monitoring of blood vessels. When the US is combined with photoacoustic (PA) imaging, where laser light pulses are used to produce sound waves in tissues, the resulting ...

PULLMAN, Wash. -- Bacteria that cause intestinal infections typically avoid a stinky chemical — one that can kill them at high enough concentrations — inside human intestines, but they may actually swim toward it when a hearty meal is the reward. “Imagine you’ve made a long journey and you’re starving,” said Arden Baylink, assistant professor. “You look for a place to eat, only to find it crowded with others and a line out the door. To make things worse, the crowd is hostile and pretty stinky. You face a dilemma: Is it worth staying to eat or should you leave?” This is the problem faced by disease-causing ...

Researchers from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and ETH Zürich have created the first integrated map detailing the metabolic and molecular changes in human blood stem cells as they age, specialize, or turn cancerous.

This work offers profound insights into stem cell health and disease, suggesting ...

Air pollution across the UK dropped between 2015 and 2024, but dangerous levels are still reached too often, shows new research published today (Tuesday, 15 July) in Environmental Science: Atmospheres. Scientists from the University of Reading studied pollution at more than 500 monitoring sites around the UK. They looked at three main types of air pollution which harm people's health. Two types of pollution got better over the decade. Nitrogen dioxide (NO2), which is mainly produced by traffic, fell by 35% on average at monitoring sites. Fine particles called PM2.5, which are small enough to get deep into lungs, dropped ...

Magnetic hysteresis loss or iron loss is an important magnetic property that determines the efficiency of electric motors and is therefore critical for electric vehicles. It occurs when the magnetic field within the motor core, made up of soft magnetic materials, is repeatedly reversed due to the changing flow of current in the windings. This reversal forces tiny magnetic regions called magnetic domains to repeatedly change their magnetization direction. This change is, however, not perfectly efficient and results in energy loss. ...

New research explains how low levels of the electrolyte sodium in the blood can disrupt the timing of the heartbeat in patients taking widely used rhythm-control medications such as flecainide, which is commonly prescribed for atrial fibrillation and other fast or irregular heart rhythms. The study, by Virginia Tech researchers at the Fralin Biomedical Research Institute in the journal Heart Rhythm, was conducted using guinea pig hearts and showed that blocking cardiac sodium channels with commonly prescribed medicine such as flecainide can make the heart’s electrical conduction unusually sensitive to even modest reductions ...

CORVALLIS, Ore. – Following a large-scale wildfire, more jaguars migrated to a study site in the Brazilian wetlands that already had the largest population density of jaguars in the world, a new study found. “Finding even more jaguars and other mammals in the study area following the 2020 wildfire and extreme drought suggests that it may serve as a climate refuge, buffering the effects of extreme climate events,” said Charlotte Eriksson, a post-doctoral scholar at Oregon State University. The 36,700-acre site is a seasonally ...

Can you imagine a life-saving molecule whose “twin” is a deadly poison? As surprising as it may seem, this chemical reality is known as “chirality”. Like a right hand and a left hand, two molecules can have the same composition, but a different shape and arrangement in space. And this difference can change everything. Understanding and controlling this phenomenon is crucial to drug design. A team from the University of Geneva (UNIGE), in collaboration with the University of Pisa, has developed a new family of remarkably stable chiral molecules. This work opens up new prospects ...

A new paper in Environmental Toxicology and Chemistry, published by Oxford University Press, finds that efforts to eradicate invasive molluscs in Idaho’s Snake River may kill off valuable freshwater species. Dreissenid mussels such as zebra and quagga mussels are invasive aquatic species that disrupt freshwater ecosystems and cause major economic and social damage. In the United States, observers first found Dreissenid mussels in the Great Lakes, likely introduced via international shipping vessels, in 1988. In subsequent decades Dreissenid mussels spread to lakes and rivers throughout the eastern and central United States, causing dramatic shifts in food chains, collapsed fisheries, ...

Every day, your body replaces billions of cells—and yet, your tissues stay perfectly organized. How is that possible? A team of researchers at ChristianaCare’s Helen F. Graham Cancer Center & Research Institute and the University of Delaware believe they’ve found an answer. In a new study published today in the scientific journal Biology of the Cell, they show that just five basic rules may explain how the body maintains the complex structure of tissues like those in the colon, for example, even as its cells are constantly dying and being replaced. This research is the product of more than 15 years of collaboration between mathematicians and cancer biologists ...

Feline infectious peritonitis, or FIP, is a serious and historically fatal disease in cats caused by a coronavirus. It behaves in many ways like severe coronavirus infections in humans, causing widespread inflammation, T cell exhaustion, and chronic immune dysfunction. Scientists at the University of California, Davis, have found that mesenchymal stromal cells, or MSC therapy, in combination with antiviral drugs, helped cats’ immune systems recover and reduced systemic inflammation. The study was published in STEM CELLS Translational Medicine. “Our findings support the idea that FIP in cats is a useful model for studying long-term immune problems after a viral infection — ...

Progress towards universal access to safe, affordable surgical care is dangerously off track as at least 160 million patients each year are unable to receive surgery - with Low- and Middle-income Countries (LMICs) bearing the brunt of the crisis, a new study reveals.  A global coalition of 60 health experts representing 20 countries is calling for urgent action to resolve the crisis – warning that only 26% of LMICs are on track to meet a target for everyone to be able to access essential surgery within 2 hours, and ...
