Study: Gene mutation disrupts sexual behavior in zebrafish

When University of Ottawa biologists Kim Mitchell and Vance Trudeau began studying the effects of gene mutations in zebrafish, they uncovered new functions that regulate how males and females interact while mating.

Americans with limited birth control access more likely to turn to the internet for abortion information

Residents of states with limited access to contraceptives and high rates of unplanned pregnancies are more likely to turn to the internet for information about abortion. These are the findings of a new study of Google search data across all 50 states by researchers at the University of California, Berkeley.

Improving IVF Treatments by Imaging Sperm Cells

News-Medical spoke to Professor Natan Shaked about his new sperm cell imaging technique that could be used to help improve the outcomes of IVF treatments.

Study hints a mechanistic link between sex and stress response in microbes

Why is sex so popular? The question of why so many organisms reproduce sexually has mystified evolutionary biologists since before Darwin, who wrote that "The whole subject is as yet hidden in darkness."

Scientists use new model to develop cancer stem cells

Liver cancer is one of the deadliest cancers. It is insidious and does not present symptoms until it has progressed considerably, at which point, treatment options are limited and chances of survival are low. The most common type of liver cancer is hepatocellular carcinoma (HCC).

Inadequate vaccine and epidemic control in the US

A new paper published on the preprint server medRxiv* in May 2020 shows that vaccination must be combined with nonpharmacological interventions (NPIs) to achieve rapid and effective control of the ongoing pandemic.

Pandemic situation in India: Too early to predict outcomes

A new paper published on the preprint server medRxiv* in May 2020 suggests that India could be facing the end of a relatively mild outbreak of COVID-19 compared with many other countries.

New insights into SARS-CoV-2 viral diversity

The first comprehensive, large-scale analysis available on the preprint server bioRxiv attempted to identify specific genomic signatures of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains within and across individual hosts – revealing recombination events, specific geographic profiles, as well as multi-strain and/or superinfections characteristic for the coronavirus disease (COVID-19) pandemic.

Potential targets discovered for COVID-19 therapy

A team of biochemists and virologists at Goethe University and the Frankfurt University Hospital were able to observe how human cells change upon infection with SARS-CoV-2, the virus causing COVID-19 in people.

Relaxation of social and physical distancing measures may result in profound mortality

Even as the world struggles to live and make a living, faced with the dual threat of a rapidly spreading viral illness and economic slowdown, a new study published on the preprint server medRxiv in May 2020 says that relaxing non-pharmacological interventions will allow the SARS-CoV-2 virus to become endemic.

Researchers develop new software to simulate breeding programs

A team of researchers at the University of Göttingen has developed an innovative software program for the simulation of breeding programs.

A broader perspective needed for population management of animals in zoos

Reproducing efficiently in captivity is crucial for the survival of many wildlife species, yet reproductive success is often lower than in the wild.

GCS centers support research to fight against global COVID-19 pandemic

In December 2019, the world learned of a new and deadly pathogen. News coming out of Wuhan, China confirmed public health experts' worst fears--a novel coronavirus appeared to have jumped from animals to humans.

Reproduction number of COVID-19 and how it relates to public health measures

A new study published on the preprint server medRxiv in May 2020 reports the use of a dynamic SEIR model to identify variations in the reproductive number of SARS-CoV-2 over time, using machine learning techniques. This could help to model and predict the outcomes of various public health solutions.

Reproduction number and herd immunity in COVID-19

A new modeling study published on the preprint server medRxiv* in May 2020 hypothesizes that the asymptomatic cases in the ongoing pandemic in Japan may far outnumber the symptomatic infections by several orders of magnitude. This has implications for future predictions and public health policies.

Researchers identify transcription factor that preserves the genomic integrity of germline

The germline is the cell lineage of an organism that passes on its genetic material to its progeny. Genetic damage to the germline can cause developmental defects and even death of that same progeny.

Viruses from stool can help fight obesity and type 2 diabetes

Obese mice with unhealthy lifestyles gain significantly less weight and avoid type 2 diabetes when they receive viruses transplanted from the stool of lean mice. These are the findings of a new University of Copenhagen study.

"Stratify-and shield" a potential alternative to COVID-19 lockdowns

Researchers in Scotland who have evaluated a “stratify-and shield” policy for combating coronavirus disease 2019 (COVID-19) in the UK say it is time to consider the approach as an alternative to social distancing seriously.

Disarmed anthrax toxin tested as a way to combat Covid-19

Disarmed anthrax toxin is being tested as a way of fighting the Covid-19 virus.

Prolonged corticosteroid treatment increases adrenal gland inflammation

New research by academics at the University of Bristol has found evidence that prolonged treatment of synthetic corticosteroid drugs increases adrenal gland inflammation in response to bacterial infection, an effect that in the long-term can damage adrenal function.
