First mRNA flu shot approved by FDA bodes well for improving drugs of the future few hurdles remain before mRNA can move beyond vaccines
From COVID-19 vaccines to Moderna’s mRNA flu vaccine, using mRNA as medicine has shown promise. But before mRNA drugs can go beyond vaccines, researchers need to identify the right diseases to treat.
Frequency and Causes of Hospital ReAdmissions among PostKidney Transplant Recipients at Specialized Centers in Khartoum, Sudan A CrossSectional Study
Background: Hospital readmissions after kidney transplantation are common and may predict future adverse outcomes. Previous studies using claims data have been limited. A better understanding of the risk factors associated with readmissions is necessary to develop accurate predictive models. Objective and Rationale: To determine the frequency, causes, and duration of hospital readmissions among post-kidney transplant recipients in specialized centers in Khartoum State, Sudan. Study Design: A descriptive, cross-sectional study. Setting and Participants: Three hundred post-kidney transplant recipients at Ahmed Gasim and Ibn Sina centers were enrolled in this study. Data on recipient, donor, and transplantation characteristics were collected. Readmission frequency, duration, causes, sites, and length of hospital stay were recorded using structured questionnaires and medical record reviews. Results: The hospital readmission rate was 39% (n = 117). Of these, 72.6% (n = 85) were readmitted only once, and infection was the leading cause of readmissions. Recipient male gender (P-value = 0.031), high body mass index (P-value = 0.014), chronic lung diseases and diabetes mellitus among comorbidities (P-value = 0.000), prior dialysis before kidney transplantation, especially peritoneal dialysis and peritoneal combined hemodialysis (P-value = 0.003), missed post-transplantation follow-up (P-value = 0.000), older-aged donor above 60 years (P-value = 0.003), kidney transplantation from second-degree related donors (P-value = 0.034), and intermediate & high immunological risks (P-value = 0.000) were major predisposing factors for hospital readmission post kidney transplantation. Conclusion: The hospital readmission rate after kidney transplantation among Sudanese recipients was high and mainly due to infection; a specific preventive program based on infection prevention and graft function monitoring should be established.

‘Only One Conclusion’: Radical Study Suggests Life on Earth Arose Twice
The fact that you, or I, or any living creature, is here at all is a series of astonishing strokes of luck stretching back more than 4 billion years.
One of the biggest hurdles was the very first one: How did life emerge from a primordial soup of stuff that very much wasn’t alive?
A radical new study, published in Science Advances, suggests that this unlikely threshold may actually have been crossed not once, but twice.
Sticky alpine flower confirms Darwin’s 150-year-old carnivorous plant prediction
A flowering plant has been confirmed as a new carnivorous lineage, according to research published in Nature Communications. The findings show that Saxifraga candelabrum can attract, trap, digest and absorb nitrogen from insects, supporting a prediction made by Charles Darwin more than 150 years ago.
While many plants exhibit carnivorous traits such as prey capture, to be formally classified as carnivorous, they must show adaptations for attracting and catching, digesting and absorbing nutrients from prey. In 1875, Charles Darwin posited that some species from the genus Saxifraga—a group of flowering plants typically found in alpine environments—may be carnivorous because of their sticky glandular hairs, which can trap insects. However, there has been a lack of conclusive evidence to support this hypothesis.
Hang Sun and colleagues studied S. candelabrum, which grows in alpine areas of the Qinghai–Tibet Plateau–Hengduan Mountains in China. Field observations and surveys of existing plant samples showed that insect prey were present on the glandular hairs of 43 out of 45 surveyed specimens, with mature plants displaying an average of 71 trapped insects in total (predominantly found on these hairs). The authors then looked for evidence of digestion and nutrient absorption to support their hypothesis.
