Study maps genes essential for metabolic function of two common bacteria

A study in Cell Reports maps genes essential for the metabolic function of M. agalactiae and M. pneumoniae, two common bacteria that infect livestock and humans respectively.

SARS-CoV-2 emergence could be due to genetic selection and recombination

Researchers have found that genetic selection and recombination could be behind the emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that leads to acute respiratory distress syndrome (ARDS) or COVID-19 disease. This research could explain COVID-19 pandemic and its emergence. The study titled, “Emergence of SARS-CoV-2 through recombination and strong purifying selection,” was published in the journal Science Advances.

A moving target identified in small cell lung tumors

Lung cancers account for approximately 25 percent of all cancer deaths. Even among those who do not smoke, 1 in 15 men and 1 in 17 women are expected to develop lung cancer in their lifetime, according to the American Cancer Society.

Neanderthal gene in women boosts infertility

It is still unclear why some women go into labor for long periods, and some face a high risk of childbirth. Also, some women fall pregnant quickly, while others may take years before they conceive. The answer may be due to a gene inherited from the Neanderthals, an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago.

Genetic shuffling and evolutionary selection may have led to SARS-CoV-2 emergence

A combination of genetic shuffling and evolutionary selection of near-identical genetic sequences among specific bat and pangolin coronaviruses may have led to the evolution of SARS-CoV-2 and its introduction into humans, a new study suggests.

Study explores how parasites respond to climate change

Warming events are increasing in magnitude and severity, threatening many ecosystems worldwide. As the global temperatures continue to climb, it also raises uncertainties as to the relationship, prevalence, and spread of parasites and disease.

Origin of SARS-CoV-2 virus well-suited to jump from animals to humans

A team of scientists studying the origin of SARS-CoV-2, the virus that has caused the COVID-19 pandemic, found that it was especially well-suited to jump from animals to humans by shapeshifting as it gained the ability to infect human cells.

New genetic engineering technique sets the stage for advances in medicine and beyond

From bacteria-made insulin that obviates the use of animal pancreases to a better understanding of infectious diseases and improved treatments, genetic engineering of bacteria has redefined modern medicine. Yet, serious limitations remain that hamper| progress in numerous other areas.

Newer treatment approaches may reduce risk of therapy-related hematologic cancers

While breakthrough treatments have emerged for several cancers over the last two decades, driving striking improvements in survival and other clinical outcomes, too little is known about the risk of therapy-related hematologic cancers following targeted and immunotherapeutic approaches.

New tool predicts COVID-19 peaks around the world

As of late May, COVID-19 has killed more than 325,000 people around the world. Even though the worst seems to be over for countries like China and South Korea, public health experts warn that cases and fatalities will continue to surge in many parts of the world.

Genomic variation and descent of SARS-CoV-2 strains in India

The pandemic of COVID-19 that is still affecting over 188 countries and territories the world over has taken over 359,000 lives in just under five months, while affecting at least 5.8 million people. Different strains have diverged from the original strain detected in Wuhan, China.

Scientists from gnomAD Consortium release first set of discoveries on human genetic variation

For the last eight years, the Genome Aggregation Database Consortium (and its predecessor, the Exome Aggregation Consortium, or ExAC), has been working with geneticists around the world to compile and study more than 125,000 exomes and 15,000 whole genomes from populations around the world.

Research provides important insights into genetic adaptation of SARS-CoV-2 to humans

In their groundbreaking paper available on the preprint server medRxiv, University of Pittsburgh researchers were appraising signals of SARS-CoV-2 genome evolution and found that purifying selection (i.e., removal of deleterious mutations) represents the dominant trait during early coronavirus disease (COVID-19) pandemic - suggesting that the virus will evolve as it diversifies in a growing number of hosts.
