  1. B cells are critical to the proper functioning of the immune system. However, researchers at Karolinska Institutet have shown that they can sometimes do more harm than good, as their numbers greatly increase after bowel damage, preventing the tissue from healing. The results, which are presented in the journal Immunity, can be of significance to the treatment of inflammatory bowel disease.
  2. A new study led by UCL researchers has identified patterns in how common health conditions occur together in the same individuals, using data from 4 million patients in England.
  3. Photoacoustic microscopy (PAM) is a relatively new imaging technique that uses laser light to induce ultrasonic vibrations in tissue. These ultrasonic vibrations, along with a computer that processes them, can then be used to create an image of the structures of the tissue in much the same way ultrasound imaging works.
  4. Gold standard treatment plans for people with early psychosis have a patchy success rate, suggesting the need to develop more tailored approaches.
  5. A large team of researchers affiliated with a host of institutions across the U.S., working with two colleagues from Sweden, reports promising results in a phase I clinical trial aimed at testing the efficacy and safety of an HIV vaccine.
  6. During the first months of the COVID-19 pandemic, clinicians across Mayo Clinic transitioned to virtual modes of care to continue to treat patients safely—resulting in an increase of over 10,000% in video telemedicine visits between patients and clinical care team members across the organization. These monumental shifts in care delivery also made for an opportunity to conduct some of the largest video telemedicine studies to date.
  7. A gene linked to autism spectrum disorders plays a critical role in early brain development and may shape the formation of both normal and atypical nerve connections in the brain, according to a new study by Weill Cornell Medicine investigators.
  8. Changes in a single gene open the door for harmful gut bacteria to set off the inflammation that drives Crohn's disease, according to a new study led by Weill Cornell Medicine and NewYork-Presbyterian investigators. These findings could one day help doctors better select targeted treatments for patients with this immune disorder.
  9. Intensive care doctors in Germany warned Thursday that hospital pediatric units in the country are stretched to breaking point in part due to rising cases of respiratory infections among infants.
  10. All that balding Indian television executive Athar Rasheed wanted was to look handsome and get married. But the 30-year-old's seemingly harmless hair transplant went fatally wrong.
  11. Cities across China further unwound COVID restrictions Friday, loosening testing and quarantine rules in the wake of nationwide protests calling for an end to lockdowns and greater political freedoms.
  12. About 80% of people with cancer suffer from significant muscle wasting, or loss of muscle tissue, and 30% of these patients die from this condition. New research in mice finds that the severity of muscle wasting is related to the type, size and location of the tumor.
  13. In a new study published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine, researchers sought to determine the percentage of COVID-19 patients discharged from the hospital who had a type of fibrotic lung damage, known as interstitial lung disease, that requires ongoing follow-up care. These patients had varying degrees of COVID-19 severity at hospital admission.
  14. The adoption of best practice front-of-pack nutrition labeling in more countries of the Americas can help reduce poor-nutrition related non-communicable diseases (NCDs) such as cardiovascular disease, type-2 diabetes, high blood pressure and some cancers in the region, a recent study led by researchers at the University of Nevada, Reno and the Pan American Health Organization (PAHO) suggests.
  15. Adding a daily ounce of peanuts or about a teaspoon of herbs and spices to your diet may affect the composition of gut bacteria, an indicator of overall health, according to new research from Penn State. In two separate studies, nutritional scientists studied the effects of small changes to the average American diet and found improvements to the gut microbiome.
  16. Exposure to traffic related air pollution is associated with an increased likelihood of having multiple long-term physical and mental health conditions, according to a new study of more than 364,000 people in England.
  17. Gamers who buy "loot boxes" are up to two times more likely to gamble, shows new research published today in the journal Addiction Research & Theory.
  18. Emergency visits for stroke are elevated after a heatwave, according to research presented today at ESC Asia, a scientific congress organized by the European Society of Cardiology (ESC), the Asian Pacific Society of Cardiology (APSC), and the Asean Federation of Cardiology (AFC).
  19. A vision for building sustainable, self-driven health care spanning primary care, secondary care and the wider health and social care system has been set out by medical innovators writing in the Journal of the Royal Society of Medicine.
  20. Rates of heart failure associated with the growing illicit use of the stimulant drug methamphetamine, or meth for short, are rising worldwide and now affect a wide range of socio-economic and racial groups, finds a review of the available evidence, published online in the journal Heart.
