Researchers optimized portable low-field MRI with machine learning to improve brain morphometry and white matter hyperintensity detection, making Alzheimer’s diagnosis more accessible and cost-effective.
Respiratory syncytial virus (RSV) is a common, contagious virus that affects your respiratory system. It spreads easily and leads to cold-like symptoms such as a runny nose and cough.
Most people with RSV have mild symptoms that go away on their own in a week or two. But RSV can lead to serious complications, especially for babies, older adults, and people with certain conditions.
If you have RSV and you can’t breathe well or you’re dehydrated, you may need to go to the hospital. You may need IV fluids, oxygen, or ventilation (which helps with your air flow).
Just 37% of kids have gotten flu shots this year, according to new CDC data. That’s down seven percentage points, from 44% of kids getting shots by this same time last year.
The data concerns health officials, especially since a record number of children died of flu-related causes last year.
Ultimately, 55% of kids got vaccinated against the flu during the 2023–24 flu season, which was the lowest rate in 12 years, a CDC official told NBC News. Vaccination rates have fallen for a variety of childhood vaccines in recent years. The trend has been blamed on vaccine fatigue after the pandemic as well as misinformation about the safety of childhood shots.
A cutting-edge X-ray method reveals the 3D orientation of nanoscale material structures, offering fresh insights into their functionality.
Researchers at the Swiss Light Source (SLS) have developed a groundbreaking technique called X-ray linear dichroic orientation tomography (XL-DOT). This method reveals the three-dimensional arrangement of a material’s structural building blocks at the nanoscale. Its first application focused on a polycrystalline catalyst, enabling scientists to visualize crystal grains, grain boundaries, and defects—critical features that influence catalyst performance. Beyond catalysis, XL-DOT offers unprecedented insights into the structure of various functional materials used in information technology, energy storage, and biomedical applications.
Research from Washington University shows that glioblastoma, a type of brain cancer, has its own internal clock that synchronizes with the host’s circadian rhythms to optimize its growth by responding to daily hormone releases like cortisol.
Targeting these circadian signals in treatment slowed tumor growth significantly in both lab and animal studies. This synchronization could explain the mixed effects of dexamethasone, a common treatment, depending on the timing of its administration. The study highlights the potential of chronotherapy, aligning treatment with the body’s natural rhythms, to improve cancer outcomes.

Air pollution is associated with increased risk of venous thromboembolism: the Multi-Ethnic Study of Atherosclerosis https://ashpublications.org/blood/article/doi/10.1182/blood.…ed-risk-of
A comprehensive longitudinal study has shown a clear link between long-term exposure to air pollution and an increased risk of developing blood clots in deep veins, known as venous thromboembolism.
The study, which followed over 6,000 U.S. adults across major cities, revealed that exposure to particulate matter, oxides of nitrogen, and nitrogen dioxide significantly heightened the risk, with those in the highest quartile of exposure facing the most severe risks.

Regarding oral HSV-1 infections, the global prevalence in 2020 among individuals aged 0–49 years was 58.6% (95% UI: 53.5–62.1%), equating to approximately 3.4 billion people. The African region exhibited the highest oral HSV-1 prevalence, while the Western Pacific had the largest number of infected individuals.
Conclusions
To summarize, in 2020, 26 million individuals aged 15–49 acquired new HSV-2 infections, with 520 million living with HSV-2 and 188 million experiencing HSV-2-related GUD. Similarly, 17 million acquired new genital HSV-1 infections, with 376 million living with genital HSV-1 and 17 million experiencing HSV-1-related GUD.
