Eight years after the technology was approved by government authorities, it can be reported that at least one child with DNA from three different people has been born to parents in the United Kingdom.

The announcement isn’t exactly ‘new’ knowledge, but reporters at The Guardian were able to prompt an official confirmation with a freedom of information request.

The University of Newcastle in collaboration with the Newcastle Fertility Center are pioneers in what is known as mitochondrial replacement therapy (MRT), a special form of in vitro fertilization (IVF) designed to prevent severe genetic diseases in future babies.

A new study in Nature hunted down another piece to the aging puzzle. In five species across the evolutionary scale—worms, flies, mice, rats, and humans—the team honed in on a critical molecular process that powers every single cell inside the body and degrades with age.

The process, called transcription, is the first step in turning our genetic material into proteins. Here, DNA letters are reworked into a “messenger” called RNA, which then shuttles the information to other parts of the cell to make proteins.

Scientists have long suspected that transcription may go awry with aging, but the new study offers proof that it doesn’t—with a twist. In all five of the species tested, as the organism grew older the process surprisingly sped up. But like trying to type faster when blindfolded, error rates also shot up.

The new version of the human genome could lead to better diagnostics and treatment of genetic diseases.

High spatial and temporal resolution

The scientists performed all these analyses on organoids that were of different ages and thus at different stages of development. In this way, they were able to create a time series of images and genetic information that describes the entire 39-week development of retinal organoids.

Year 2022 These animals have fire resistance which could allow humans to essentially be more fire resistant. I still believe the best gene hack would be a tardigrade essentially because they gave so many survival genes.

Echidnas are among the last mammals on Earth to lay eggs, but that’s not what makes them so miraculous.

Human lifespan is intricately connected to the aging process of individual cells, and this means that scientists have spent decades trying to unravel the mysteries of cellular aging and exploring methods to slow down the ticking of the aging clock.

Longevity. Technology: In 2020, a group of researchers from the University of California San Diego identified two distinct mechanisms of cellular aging and genetically manipulated them to extend cell lifespan [1]. Now, their research has progressed to employ synthetic biology and gene circuits to delay the deterioration associated with cellular aging [2]. The team’s innovative approach could revolutionize scientific methods of aging prevention and contribute to reprogramming aging pathways in various human cell types.

Publishing in Science, the researchers describe how cells in yeast, plants, animals and humans all contain gene regulatory circuits responsible for several physiological functions, including aging. These gene circuits, akin to electric circuits controlling household devices, can operate in different ways, and the UC San Diego team discovered that cells don’t necessarily age the same way – it all depends on their genetic material and environment. The researchers found that cells can age either through DNA stability decline or mitochondrial decline.
