In a new multidisciplinary study, researchers at Texas A&M University showed how quantum computing—a new kind of computing that can process additional types of data—can assist with genetic research and used it to discover new links between genes that scientists were previously unable to detect.

Their project used the new computing technology to map gene regulatory networks (GRNs), which provide information about how genes can cause each other to activate or deactivate.

As the team published in npj Quantum Information, quantum computing will help scientists more accurately predict relationships between genes, which could have huge implications for both animal and human medicine.

Advancements in genetic engineering, gene therapies, and anti-aging research may eventually allow for age reversal and the restoration of youthful health and longevity.

Every cell in the human body contains the same genetic instructions, encoded in its DNA. However, out of about 30,000 genes, each cell expresses only those genes that it needs to become a nerve cell, immune cell, or any of the other hundreds of cell types in the body.

Each cell’s fate is largely determined by chemical modifications to the proteins that decorate its DNA; these modification in turn control which genes get turned on or off. When cells copy their DNA to divide, however, they lose half of these modifications, leaving the question: How do cells maintain the memory of what kind of cell they are supposed to be?

A new MIT study proposes a theoretical model that helps explain how these memories are passed from generation to generation when cells divide. The research team suggests that within each cell’s nucleus, the 3D folding pattern of its genome determines which parts of the genome will be marked by these chemical modifications.

Researchers at the University of Pittsburgh and KU Leuven have discovered a suite of genes that influence head shape in humans. These findings, published this week in Nature Communications, help explain the diversity of human head shapes and may also offer important clues about the genetic basis of conditions that affect the skull, such as craniosynostosis.

By analyzing measurements of the cranial vault —the part of the skull that forms the rounded top of the head and protects the brain—the team identified 30 regions of the genome associated with different aspects of head shape, 29 of which have not been reported previously.

“Anthropologists have speculated and debated the genetics of cranial vault shape since the early 20th century,” said co-senior author Seth Weinberg, Ph.D., professor of oral and craniofacial sciences in the Pitt School of Dental Medicine and co-director of the Center for Craniofacial and Dental Genetics.

Researchers from the Faculty of Medicine and Surgery at the Catholic University, Rome and the Fondazione Policlinico Universitario A. Gemelli IRCCS have developed an engineered protein that boosts memory.

Neuroscientists at the Faculty of Medicine and Surgery of the Catholic University, Rome, and the Fondazione Policlinico Universitario Agostino Gemelli IRCCS have genetically modified a molecule, the protein LIMK1, which is normally active in the brain, with a key role in memory.

They added a “molecular switch” that is activated by administering a drug, rapamycin, known for its several anti-aging effects on the brain.

Compact genetic testing device created for Covid-19 could be used to detect a range of pathogens, or conditions including cancer.

A virus diagnosis device that gives lab-quality results within just three minutes has been invented by engineers at the University of Bath, who describe it as the ‘world’s fastest Covid test’

The prototype LoCKAmp device uses innovative ‘lab on a chip’ technology and has been proven to provide rapid and low-cost detection of Covid-19 from nasal swabs. The research team, based at the University of Bath, say the technology could easily be adapted to detect other pathogens such as bacteria — or even conditions like cancer.

In a world first, regulators in the U.K. approved Crispr’s gene-editing treatment for two blood diseases on Thursday, and CRSP stock surged.

Findings lay the groundwork for developing targeted therapies aimed at regulating epigenetic factors in cancer therapy.

The one-time treatment helped relieve symptoms of disease and could free patients from the need for bone marrow transplants or regular blood transfusions, Beach said, adding that the drug hopefully offers a permanent fix for the condition.

The MHRA said it identified no significant safety concerns during the trials and will continue to closely monitor Casgevy’s safety after approval.

Vertex CEO and President Reshma Kewalramanit celebrated Casgevy’s approval as “a historic day in science and medicine” and Samarth Kulkarni, CEO and Chairman of Crispr Therapeutics, said it will hopefully mark “the first of many applications of this Nobel Prize winning technology to benefit eligible patients with serious diseases.” The two companies are hoping for similarly positive decisions from the MHRA’s counterparts in the Europe Union and the U.S., which are in the process of evaluating Casgevy, also known as exa-cel. The Food and Drug Administration is expected to make a decision in early December and has a deadline of December 8. The agency appears poised to follow the MHRA and approve the treatment, with its advisors confident of the drug’s efficacy and benefit but wary of theoretical unintended consequences of genetic modifications.
