Summary: Researchers have uncovered genes essential for learning, memory, aggression, and other complex behaviors originated around 650 million years ago.

The study utilized computational methods to trace the evolutionary history of these genes involved in the production, modulation, and reception of monoamines like serotonin, dopamine, and adrenaline. This discovery suggests that this new method of modulating neuronal circuits could have played a role in the Cambrian Explosion, contributing to the diversification of life.

The finding offers new research avenues to understand the origins of complex behaviors and their relation to diverse processes like reward, addiction, aggression, feeding, and sleep.

The immune system is an incredibly complex network that has some amazing capabilities. It can eliminate dangerous cells that may lead to cancer, and defend the body against a wide variety of pathogenic invaders. It also has the ability to remember those encounters with pathogens so if they happen again, the immune system is primed to respond more quickly and forcefully against the offender. Scientists have now learned more about how the immune system memory is created at the molecular level. The findings have been reported in Science Immunology.

When immune cells are exposed to an invader, they can recognize structures called antigens on the surface of the pathogen. In this study, the researchers compared immune cells that had never been exposed to an antigen, so-called naive cells, to immune cells that had been in contact with an antigen, known as memory cells. The investigators wanted to identify the epigenetic differences between these cell types, which are changes in DNA that can impact gene expression, such as structural shifts or chemical tags, but do not alter the sequence of the genome. Epigenetic changes might explain why memory cells can react so quickly while naive cells are comparatively slow.

Working to integrate theology, ethics and science, ISCAT Fellow and renowned author Dr. Brian Edgar discusses the future of humanity.

The immune system is one of the most complex parts of our body. It keeps us healthy by getting rid of parasites, viruses or bacteria, and by destroying damaged or cancer cells. One of its most intriguing abilities is its memory: upon first contact with a foreign component (called antigens) our adaptive immune system takes around two weeks to respond, but responses afterwards are much faster, as if the cells remembered the antigen. But how is this memory attained?

In a recent publication, a team of researchers coordinated by Dr. Ralph Stadhouders, from Erasmus MC, and Dr. Gregoire Stik, Group Leader at the Josep Carreras Leukemia Research Institute, provides new clues on immune memory using state-of-the-art methodologies.

In their research paper, published in the journal Science Immunology, the first-author Anne Onrust-van Schoonhoven and colleagues compared the response of immune cells that had never been in contact with an antigen (called naïve cells) with cells previously exposed to antigen (memory cells) and sort of knew it. They focused on the differences in the epigenetic control of the cellular machinery and the nuclear architecture of the cells, two mechanisms that could explain the quick activation pattern of memory cells.

A national study, led by researchers at Tufts Medical Center, has found whole genome sequencing (WGS) to be nearly twice as effective as a targeted gene sequencing test at identifying abnormalities responsible for genetic disorders in newborns and infants. The Genomic Medicine in Ill Infants and Newborns (GEMINI) study did, however, find that time to results was longer when carrying out WGS, when compared with a commercially available targeted neonatal gene-sequencing test.

“More than half of the babies in our study had a genetic disorder that would have remained undetected at most hospitals across the country if not for genome sequencing technologies,” said Jonathan Davis, MD, chief of newborn medicine at Tufts Medical Center and co-principal investigator of the study. “Successfully diagnosing an infant’s genetic disorder as early as possible helps ensure they receive the best medical care. This study shows that WGS, while still imperfect, remains the gold standard for accurate diagnosis of genetic disorders in newborns and infants.”

The study, “A Comparative Analysis of Rapid Whole Genomic Sequencing and a Targeted Neonatal Gene Panel in Infants with a Suspected Genetic Disorder: The Genomic Medicine for Ill Neonates and Infants (GEMINI) Study,” is reported in The Journal of the American Medical Association (J AMA).

Connected technology tools can be stepping-stones to a new world in diverse areas such as genetic engineering, augmented reality, robotics, and renewable energies. But they need cyber protection.

Last year, the chemist – who is an emeritus professor at the University of Strasbourg – published a book titled The Elegance of Molecules. In the pages, he lets his imagination run wild. “Over time, most of the chemical reactions that govern nature could be controlled or imitated by a nanorobot: counter-offensives by the immune system, the production of antibodies, hormones on demand, the repairing of damaged cells and organs [or] the correction of anomalies in the genetic text,” Sauvage writes. “None of this will belong in the realm of science fiction in the long-term.”

Sitting in the hotel’s restaurant, however, the researcher’s realism contrasts with his futuristic fantasy. “Today, we can’t do much. Molecular machines are a somewhat new concept: we can make molecules that move as we choose [and] we can make a fairly complex molecule perform a rotary motion. Or we can make it behave like a muscle, stretching and contracting. The applications will arrive in the future, but we’re not there yet,” he stresses.

The French researcher has been developing these molecular muscles since 2002 alongside a Spanish chemist – María Consuelo Jiménez – from the Polytechnic University of Valencia. “The first thing was to show that we can make a molecule that contracts and stretches. Now, you can think of making materials – especially fibers – that can contract and stretch. Perhaps artificial muscles could be made to replace damaged muscles in people, but that will be in the future. At the moment, there are no real applications,” Sauvage clarifies.
