Increase in social stress may be connected to global population decline

A University of Massachusetts Amherst environmental health scientist has developed an "overlooked hypothesis" to help explain the projected global population decline beginning in 2064: social stress.

Optimized strategy for generating male germ-cells from mouse pluripotent stem cells

For species that rely on sexual reproduction, including mice and men, offspring can only happen if sperm from the male fertilize eggs from the female.

Study explores how couples regard fertility and family formation

The view of one's own fertility and having children has significantly changed in the last 60 years. In a new study, researchers engaged with more than one hundred Swedes between the ages of 17-90 to discuss how they regard fertility and family formation.

SARS-CoV-2 epidemic management undermined by relationship between symptoms and secondary transmission

A new study provides evidence of the correlation and estimated the period between the generation interval and incubation period of SARS-CoV-2.

Hypopituitarism and COVID-19 – exploring a possible bidirectional relationship?

In a recent study published in Reviews in Endocrine and Metabolic Disorders, the researchers discuss the extra-pulmonary manifestations of COVID-19.

Temperature variations could have driven the division of protocells

A simple mechanism could underlie the growth and self-replication of protocells-;putative ancestors of modern living cells-;suggests a study publishing September 3 in Biophysical Journal.

Increased transmissibility drives SARS-CoV-2 variant spread, aided by immune escape

Numerous variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have emerged over the last few months. Unfortunately, this has driven new coronavirus disease 2019 (COVID-19) waves, often more severe than before. A recent study posted to the medRxiv* preprint server discusses the characteristics of the variant that is responsible for this phenomenon.

Scientists analyze the impact of two strategies in stopping COVID-19 pandemic

How can we best organise on-site workplace and school attendance periods and remote work to slow the circulation of Sars-CoV-2? Is it better to separate classes? Bring your whole team in at the same time? Set this up on daily or weekly schedules?

Studies offer insight into how the human body develops and acquires mutations throughout life

New insights into how the human body develops from one cell into trillions, and the genetic mutations that cells pick up along the way, have been generated by two studies from scientists at the Wellcome Sanger Institute, the University of Cambridge and their collaborators.

Population peak could contribute to less meaningful social interactions and reproduction suppression

A predicted population drop at the end of the century could be explained by stress from meaningless social interactions, according to a review article published in the Endocrine Society's journal, Endocrinology.

Heidelberg researchers focus on developing drugs against flavi- and coronaviruses

New drugs are intended to help stop viral zoonoses - infections that jump from animals to humans. To study suitable inhibitors, Prof. Dr Christian Klein from the Institute of Pharmacy and Molecular Biotechnology of Heidelberg University is receiving funding in the amount of 450,000 euros from the Volkswagen Foundation.

New discovery offers several approaches to fight visceral obesity

Pioneering mouse study offers new therapeutic avenues for reducing visceral fat stores, which have been associated with cardiovascular disease and multiple types of cancer.

COVID-19 risks likely to shift from older adults to younger children

Within the next few years, as the SARS-CoV-2 virus becomes endemic in the global population, COVID-19 may behave like other common-cold coronaviruses, affecting mostly young children who have not yet been vaccinated or exposed to the virus, according to new modeling results.

Microbe transmitted between mosquitoes could be key to controlling malaria

A microbe that is transmitted between male and female mosquitoes but can also block reproduction could be key to controlling malaria by targeting its release into mosquito populations, a study says.

New estimate of total immunity to SARS-CoV-2 in Texas

According to researchers in Texas, a lack of appropriate testing in the US has led to an underestimation of seroprevalence in the U.S., thus making it difficult to estimate population immunity to SARS-CoV-2 or vaccination.

Controlling the spread of SARS-CoV-2 at a large public university

Researchers from the U.S. recently reported a multimodal "SHIELD: Target, Test, and Tell" program that helped mitigate the transmission of SARS-CoV-2 at a large public university. The program also prevented community transmission and helped the continuation of in-person classes during the pandemic. This study is available on the medRxiv* preprint server.

First data-driven deep learning model can predict COVID-19 outbreak two weeks in advance

People's social behavior, reflected in their mobility data, is providing scientists with a way to forecast the spread of COVID-19 nationwide at the county level.

Invasive 'famine weed' could escalate the spread of malaria

An invasive weed could escalate the spread of malaria in East Africa after scientists found new evidence that it creates a favourable breeding ground for female mosquitoes, which transmit malaria.

Study offers genetic insights into the underlying biology of reproductive aging

The age at which women go through menopause is critical for fertility and impacts healthy ageing in women, but reproductive ageing has been difficult for scientists to study and insights into the underlying biology are limited.

SARS-CoV-2 interacts with unusual RNA structures in human cells

The study, published in the journal Nucleic Acids Research, demonstrated that G4 ligands, the chemical that binds with G4s, prevent this interaction. The results could pave the way for developing inhibitors of these interactions as potential antiviral compounds.
