"Increasing the CO2 concentration to just 800 parts per million, a level widely identified as being a marker of good ventilation, significantly extended the life spans of multiple SARS-CoV-2 variants. At higher concentrations — like those you might expect to find in a crowded, poorly ventilated room — Haddrell’s team found that 10 times as much virus remained infectious after 40 minutes when compared to clean air."
Snippet: HERVs are “non-coding” sequences comprising of genetic material that originated from the infection of germ cells with ancient retroviruses during evolution, which now constitute approximately 8% of the human genome7,8,9.

Chronic asthma could be caused by cell overcrowding in the airways.
Science News reports: "A glitch in the mechanical process that drives normal turnover of epithelial cells lining the lungs could be to blame. ... Better understanding of this physical force underpinning chronic asthma attacks might lead to new ways of combating the disease."
Biodiversity Loss Increases the Risk of Disease Outbreaks, Analysis Suggests
"Researchers found that human-caused environmental changes are driving the severity and prevalence of disease, putting people, animals and plants at risk"
Diseases are used for swearing in Dutch – but how does that work? @sesquiotic analyses the idiom "sjouw me de tering" in a new post on the Strong Language blog:

Scientists have long known a #gene called #APOE4 is one of many things that can increase people’s risk for #Alzheimer's, including simply getting older. The vast majority of Alzheimer’s cases occur after age 65. But #research published Monday suggests that for people who carry not one but two copies of the gene, it's more than a risk factor, it's an underlying cause of the mind-robbing #disease.
Scientists have identified a genetic form of Alzheimer’s disease in older people, pinpointing a gene of which some people carry two copies. The gene, called APOE4, is not only a risk factor but an underlying cause for the disease when found twice in a person’s DNA, researchers say. Finding a way to target APOE4 in treatment is crucial because Leqembi, the only drug found to slow the disease, causes dangerous side effects in people with the gene. The Associated Press has more.
