  1. Cardio-oncology is the name given to the comparatively new field of research into the connections between cardiovascular diseases and cancer, the two most common causes of death in industrialized Western countries such as Austria. As the prognosis for cancer patients improves, the phenomenon of cardiotoxicity is becoming increasingly significant. This is damage to patients' hearts caused or exacerbated by chemotherapy and/or radiotherapy.
  2. A study, recently published in the European Journal of Social Psychology and completed at the University of Helsinki, investigated people's judgments toward decisions made by nursing robots.
  3. Scientists have identified immune cell types that could be targeted to develop specific immunotherapies in chemotherapy-resistant breast cancers.
  4. In the early stages of the COVID-19 pandemic, the coronavirus was everywhere—stuck to our cellphone screens, smeared on our mail, dangling from doorknobs, even clinging to our cereal boxes. Except that it wasn't.
  5. Research conducted by Western Sydney University reveals young people in Australia are not receiving adequate information or education about periods and menstrual management.
  6. Demand for donor livers for transplant patients outstrips supply with over 15% of waitlist patients dying after a year. A new international study offers support for increasing the use of living donor liver transplantation (LDLT) in Western countries and reducing the imbalance between organ supply and demand. This study is reported in the Journal of Hepatology.
  7. A new study conducted by University of Malaga researcher Inés Moreno, in collaboration with the University of Texas, has identified a potential non-invasive therapy that could check the progress of Alzheimer's disease, the major form of dementia in the elderly population.
  8. The flow velocity in our digestive system directly determines how well nutrients are absorbed by the intestine and how many bacteria live inside it. This is the result of a new study by researchers from the Technical University of Munich (TUM) and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS). The researchers revealed the physics mechanisms of how the intestine can regulate itself to optimize nutrient absorption while limiting unwanted bacterial growth at the same time.
  9. Pediatric Early Warning Systems (PEWS)—bedside tools used by nurses to assess the health of hospitalized children and identify urgent medical issues—are not widely used in resource-limited hospitals, in part due to challenges with implementation. A recent article published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society, reports on a successful collaboration to support implementation of a PEWS for children with cancer in Latin American hospitals.
  10. Patients with chronic heart failure who received collaborative, home-based palliative care were less likely to die in hospital and more likely to die at home than people who received usual care, according to new research in Canadian Medical Association Journal (CMAJ).
  11. From 2019 to 2020, more than 11,000 people who had been using drugs were treated in U.S. emergency departments for injuries that occurred while riding a bicycle, according to a new report in the Journal of Studies on Alcohol and Drugs.
  12. Simple computer exercises using positive words and images designed to boost self-worth can prolong the antidepressant effects of ketamine in people with depression. That's what my research team and I found in our new study.
  13. Babies in the womb are big fans of carrots but not so much leafy green vegetables—and show it in their faces, scientists said in a new study published Thursday.
  14. Neutrophils, the most abundant type of white blood cell, are the body's first line of defense against infection. Foreign pathogens can stress the body and activate neutrophils. When activated, neutrophils employ various weapons to protect the body. But if overactivated, these weapons can damage the body's own tissues. Lung tissue is saturated with blood vessels, making them very susceptible to neutrophil attacks. If severe enough, acute lung injuries can lead to acute respiratory distress syndrome (ARDS), the leading cause of death due to COVID-19.
  15. Many asexual individuals, those with little to no sexual attraction, are in long-term satisfying romantic relationships, but there has been little study on how and why they last and thrive. New research from Michigan State University found that, despite asexuals' lack of or dislike for sexual attraction, the ingredients that make for a successful relationship among asexual individuals are virtually the same as those in any other relationship.
  16. Scientists at Rensselaer Polytechnic Institute (RPI), through biomolecular research and testing, have discovered a potential topical therapeutic to treat monkeypox. The research stems from years of study spent on investigating the structures of viruses such as zika, Dengue, herpes, coronaviruses, and hepatitis. The past research and expertise in the interaction of virus proteins and polysaccharides, including existing drugs, aided researchers in the rapid discovery of a potential therapeutic. The work is in its early stages; however, the researchers believe that because the drugs used in the work are FDA-approved, there would be a rapid pathway for clinical testing and potential approval as a monkeypox therapy. This timely research has been published in Molecules recently.
  17. In a new paper, University of California, Irvine researchers explain how precision genome editing agents have enabled precise gene correction and disease rescue in inherited retinal diseases (IRDs). The study, titled, "Precision genome editing in the eye," was published this week in the Proceedings of the National Academy of Sciences.
  18. The gurus of the psychedelic era of American pop culture extolled the experience of the "acid trip." But the U.S. government and much of the public remained leery of LSD, with President Richard Nixon declaring it and assorted other drugs "public enemy No. 1."
  19. The way in which we experience music and speech differs from what has until now been believed. This is the conclusion of a study by researchers at Linköping University, Sweden, and the Oregon Health and Science University, U.S. The results have been published in Science Advances, and may make it possible to design better cochlear implants.
  20. Formulas for toddlers are a burgeoning business in the United States: Sales of the drinks more than doubled in recent years as companies convinced parents that their little ones needed the liquid boost. But many experts warn that these products, designed for children ages 1 to 3, fill no nutritional needs beyond what is available in a typical toddler diet, are subject to less regulation than infant formula, and are expensive.
