Gene that controls early social behavior may help to understand Autism: Study | Health

A new animal study has identified a gene essential for the early development of basic social behaviors. The study was published in the journal Science Advances. The work also suggests that exposure to certain drugs and environmental risk factors during embryonic development can cause changes to this gene, leading to alterations in social behavior that … Read more

Researchers discover a new function of CRISPR/Cas9 gene scissors

For several years now, the CRISPR/Cas9 gene scissors have been causing a sensation in science and medicine. This new tool of molecular biology has its origins in an ancient bacterial immune system. It protects bacteria from attack by so-called phages, ie viruses that infect bacteria. Researchers from the Institute of Structural Biology at the University … Read more

Scientists investigate the evolutionary origin of SARS-CoV-2 using recombination-aware phylogenetic analysis

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and severe acute respiratory syndrome coronavirus (SARS-CoV) are members of the subgenus Sarbecovirus, whose genomic length is around 30,000 base pairs. These viruses encode four structural proteins, namely spike (S), envelope (E), membrane (M), and nucleocapsid (N). Study: Recombination-aware phylogenetic analysis sheds light on the evolutionary origin of … Read more

The potential of Sofosbuvir against COVID-19 neurological symptoms

On 11th March 2020, the World Health Organization (WHO) announced the global spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as the coronavirus disease 2019 (COVID-19). Despite the discovery of effective COVID-19 vaccines and the subsequent commencement of vaccination programs globally, SARS-CoV-2 infections have been widely reported due to the emergence of new … Read more

BW.1- a new Omicron subvariant that escapes immunity

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of the coronavirus disease 2019 (COVID-19), continues to evolve through genomic mutations. Emerging SARS-CoV-2 variants have been categorized as variants of interest (VOI) and variants of concern (VOC) based on their infectiousness, virulence, and capacity to evade immune responses induced through both natural infection … Read more

Fossils of a tiny sea creature solve century-old debate over brain evolution in arthropods

Fossils of a tiny sea creature that died more than half a billion years ago may compel a science textbook rewrite of how brains evolved. A study published in Science – led by Nicholas Strausfeld, a Regents Professor in the University of Arizona Department of Neuroscience, and Frank Hirth, a reader of evolutionary neuroscience at … Read more

Wearable activity tracker data can be used to obtain metrics associated with the user’s physical health

A new Johns Hopkins study shows that data gathered from wearable activity trackers can be used to obtain several metrics associated with the user’s general physical health and cardiovascular health status. While these sensors are generally marketed as daily step counters, the Johns Hopkins research team believes they could potentially serve a greater purpose: supporting … Read more

As STDS proliferate, companies rush to market at-home test kits. But are they reliable?

Among the more remarkable legacies of the covid-19 pandemic is how quickly federal regulators, the health care industry, and consumers moved to make at-home testing a reliable tool for managing a public health crisis. But that fast-track focus is missing from another, less publicized epidemic: an explosion in sexually transmitted diseases that can cause chronic … Read more

Lower methionine intake may decrease postmenopausal cancer risk

Evidence indicates the role of dietary composition in driving systemic environmental changes, or epigenetics, which sustain cancer cell progression. Methionine is an amino acid found in meat, nuts, eggs, and grains that is important for metabolic health, but overconsumption can stimulate changes in DNA methylation, leading to cancer cell proliferation. However, in vivo tests demonstrate … Read more
