Hello, and welcome to the #bioscinews round-up! This is the place where you can find all the important biosci new stories from the past week, in a short, digestible paragraph.

This week’s news

The Tardigrade genome was sequenced and found to contain more foreign genes than any previously sequenced animal genome. Tardigrades are extromophiles, meaning they can survive in conditions that would kill most organisms (they’ve even survived the cold and radiation of space!). It is thought that these wondrous little creatures pick up this foreign DNA when they dessicate (which helps them survive extreme conditions), in a similar way to Bdelloid rotifers. Since Bdelloids also dessicate to survive unideal conditions, there is a possibility that horizontal gene transfer is more common among extremophilic animals than previously thought.

Tardigrades!

A new immunotherapy method may change how Type I Diabetes is treated in the future, and may even help prevent the progression of the disease. Since Type I Diabetes is an autoimmune disease, the new approach targets the regulatory T (T-reg) cells of the immune system. In affected patients, the T-reg cells target the insulin-producing cells of the pancreas and destroy them, meaning that Type I diabetics need to inject insulin daily to combat this lack of insulin production by their bodies. By replacing the T-reg cells in a patient, researchers have prevented diabetic symptoms in early-onset patients and the slowing of the disease progression was also observed. Hopefully, further trials will continue to show promise.

This week’s news

Hypothesised fat-burning regulatory genes. Researchers have proposed a genetic pathway that is involved in adipocyte thermogenesis – in lamens terms – genes that regulate heat generation from fat in fat cells in the human body.

Vitamin D and Multiple Sclerosis. Some people are genetically prone to have low vitamin D levels (as Vit D is produced by the body when sunlight hits the skin), and this has now been associated with a higher risk of developing MS.

Novel antibiotic from chestnut leaves. Working on historical botanical cures for infections, a novel antibiotic has been discovered in chestnut leaves, which is active against super bugs – such as ones with high levels of antibiotic resistance.

Ants self-medicating. Despite being poisonous, for the first time, ants have been shown to consume foods rich in hydrogen peroxide, if they have a dangerous fungal disease, as a method to treat themselves.
