Bacteria can be found everywhere, but did you know we each have different bacterial colonies living on our skin? With the help of their distinctive qualities, perhaps they can aid us in solving crimes.
Identity, parentage, innocence. These are some of the things that can be determined with even just a small amount of DNA. But what if… we can do more? What if I can infer what you look like without ever having met you, just by looking at your DNA? Scientists strive to do just that.
The organs in pigs can be suitable for human transplantation. They are nearly identical to human organs in terms of activity and size. However, every animal’s genome is loaded with integrated viruses. The viruses that are present in pigs are mostly harmless to them, but could lead to tumor growth and defects in the immune system if they were to be passed on to humans. A recent research paper tried to tackle these problems with the use of molecular scissors to edit the viruses out of the pig genome.
The secret to a long life has always been a topic of intrigue and fascination. Genome-wide studies of people with different life spans have revealed key genes that contribute to a longer life. Moreover, genes involved in longevity were found to be correlated with coronary heart disease, type 2 diabetes and father’s age at death.
Viruses are more prevalent than once thought, with a significant role in development of humanity. A recent consensus approach based on whole genome and whole transcriptome sequencing reveals which human cancers are caused by viral infections.
A growing problem doctors face is that the primary cell type that produces cancer is sometimes undetermined. This leaves patients with generalized treatment options and a lower survival chance. However, with the use of neural networks and DNA sequencing, there seems to be hope for identifying these primary sites and providing specialized treatment. But what aspects of the genome gives us the best clues and why might some cancer types be harder to identify?
Recent studies in genomics have made a step towards personalized care for cancer patients. Loss of essential genes may limit the effectiveness of treatments that activate the immune system to fight cancer.
For generations, biologists have aimed to understand every single process of life. The key to moving closer to this goal is to further understand the compounds that govern almost all life processes, i.e. proteins. AlphaFold, a revolutionary new AI tool holds the potential to give us the power to evaluate protein structures like never before, further breaking barriers for advancements in research as well as medicine.
Alzheimer’s is a devastating disease. Does it have to stay that way? A recent genomics study suggests it may not.
Well, not exactly. Ancient birds are theorized to have evolved from dinosaurs over 150 million years ago. But exactly how similar were they? While analyzing chromosomal-level differences, researchers revealed the genomic characteristics of an ancient common ancestor.
