Scientists have probed the molecular origins of recombination in RNA viruses. Hiccups during the copying process of viruses cause recombination to take place: the exchange of segments of viral RNA. While this can lead to the emergence of new virus variants, the mechanism can also be exploited to induce non-viable defective viruses

With the WASA detector, a very special instrument is currently being set up at GSI/FAIR. Together with the fragment separator FRS, it will be used to produce and study so-called hypernuclei during the upcoming experiment period of FAIR Phase 0 in 2022. For this purpose, the assembly, which weighs several tons, is being transferred to the facility in a complex installation procedure.

A Hox gene, a major developmental gene that regulates the identity of structures on the segments of black-tailed bumblebees (Bombus melanopygus), turns on a complex set of downstream genes that ultimately drive segmental changes in bumblebees’ pigmentation, according to new research. Bumblebees exhibit exceptional color diversity, with the approximately 260 species displaying more than 400 [...]

Researchers found that inhaling unfragmented hyaluronan improves lung function in patients suffering from severe exacerbation of chronic obstructive pulmonary disease (COPD). Hyaluronan, a sugar secreted by living tissue that acts as a scaffold for cells, is also used in cosmetics as a skin moisturizer and as a nasal spray to moisturize lung airways. Utilized as a treatment, hyaluronan decreased the number of days in the hospital.

With age, the human heart gradually loses its ability to repair itself following injury. Damage wrought by injuries such as cardiac ischemia and heart attack, which are associated with decreased oxygen levels in the heart, can cause the heart to function below normal capacity, making it difficult for patients to carry out day-to-day activities. To augment heart repair after ischemic injury, researchers have turned to stem cell-based therapies, which replace dead heart tissue with new, functional tissue.

These two houses have been built through a long process of research, design, and experimentation on materials, technology, and program. The binding element of this process was the courage and trust of the client who accepted to be part of a journey of which these two buildings are only a fragment. 

People with more severe obstructive sleep apnea and reductions in blood oxygen concentrations are more likely to have elevated concentrations of triglycerides in the blood, according to new research. “Obstructive sleep apnea (OSA) is a syndrome characterized by partial or complete obstruction of the upper airways, resulting in intermittent hypoxia, variably accompanied by sleep fragmentation [...]

Consumption of ultra-processed foods has increased over the past two decades across nearly all segments of the U.S. population, according to a new study.

Plans to auction the fragment, which depicts the head of an ancient ruler, sparked a row in 2019.
