CovMT could help researchers to track evolution of SARS-CoV-2 mutations

A SARS-CoV-2 tracker uses publicly available sequencing data to show how the virus is changing and spreading over time. The tracker, called CovMT, was developed at KAUST and is expected to help researchers and policymakers understand the evolution of the virus's mutations.

Study illuminates the role of HAND2 gene in timing of human labor

A new study illuminates how a gene called HAND2 may have a hand in the timing of human labor.

Superspreader events trigger emergence of novel SARS-CoV-2 variants in USA

A team of scientists from the USA and Germany has recently studied the evolution of SARS-CoV-2 in a representative set of sequences from the USA collected between 2020 and 2021. The findings reveal that the viral genome has accumulated multiple mutations over time with only occasional loss of mutation. The main driving forces behind such genetic variations include widespread infection and superspreader events.

Salt reduction program will lead to health benefits, cost savings by 2050

England's salt reduction programme will have led to nearly 200,000 fewer adults developing heart disease and £1.64 billion of healthcare cost savings by 2050, according to research by Queen Mary University of London.

Evolution of the spike gene of SARS-CoV-2 for human adaptation

Researchers have found a 96% similarity in nucleotide sequence between bat coronavirus (RaTG13), isolated from Rhinolophus affinis bats in China in 2013, and SARS-CoV-2 and ~97% amino acid similarity with the Spike (S) protein. This S protein performs two essential roles, i.e., mediates receptor-binding and membrane fusion. Hence, spike protein is regarded as a key coronavirus determinant of host tropism.

Scientists describe genetic mechanisms behind mating process of ciliates

Conjugation (or mating) of ciliates is a unique phenomenon among living beings. They have sex not for reproduction or pleasure — they seek to increase genetic variation.

Researchers use zebrafish to study cancer-immune interactions

Cancer researcher Rita Fior uses zebrafish to study human cancer. Though this may seem like an unlikely match, her work shows great promise with forthcoming applications in personalized medicine.

New study to explore how Apple Watch can provide early warning for worsening heart failure

As part of the University Health Network, renowned cardiologist Dr. Heather Ross has launched a new clinical study, in collaboration with Apple to test if remote monitoring with Apple Watch can help with early identification of worsening heart failure.

Cone snail venom could potentially treat severe forms of malaria

Severe forms of malaria such as Plasmodium falciparum may be deadly even after treatment with current parasite-killing drugs.

One in five people lack protein α-actinin-3 in their muscle fiber, shows study

Almost one in five people lack the protein α-actinin-3 in their muscle fibers. Researchers at Karolinska Institutet in Sweden now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibers, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibers.

Where might future novel coronaviruses come from?

The researchers predicted many more associations between coronaviruses and host species than have been observed to date. They also predicted 30 times more potential recombination hosts of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Scientists examine DNA repair pathways and their impact on cancer evolution

DNA repair pathways exist to correct molecular damage caused by internal and external factors. However, any damage to these pathways can result in the creation of tumors and specific types of cancers.

Psychological variables account for anxiety and depression among pregnant women during COVID-19

Women who gave birth during the COVID-19 pandemic report having felt greater stress in the delivery process, and rate lower the quality of care received.

Drastic population collapse in Central Africa was caused by prolonged disease epidemic, indicates study

A new study published in the journal Science Advances shows that Bantu-speaking communities in the Congo rainforest underwent a major population collapse from 1600 to 1400 years ago, probably due to a prolonged disease epidemic, and that significant resettlement did not restart until around 1000 years ago.

Detection of emerging SARS-CoV-2 variant in New York

Researchers at the California Institute of Technology in Pasadena have developed a software tool called "Variant Database" that has detected an emerging lineage of severe acute respiratory coronavirus 2 (SARS-CoV-2) isolates in New York.

New model to better predict risk of abdominal aortic aneurysms

An abdominal aortic aneurysm (AAA) can be a ticking time bomb if undiscovered in time. However, researchers at the University of Pittsburgh are developing a new model to better predict at-risk patients. And the tools they are using apply mechanical testing to the human body - which is itself a complex machine.
