Hot flushes and night sweats may increase woman's risk of cardiovascular events

New research from The University of Queensland has found that women who have hot flushes and night sweats after menopause are 70 per cent more likely to have heart attacks, angina and strokes.

Researchers identify the world’s lightest electromagnetic shielding material

Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals.

Novavax SARS-CoV-2 vaccine candidate shows promise in animal models

A new study published on the preprint server bioRxiv in June 2020 shows that a candidate spike protein vaccine can induce neutralizing antibodies, antiviral T cell responses, and protection against infection.

How lockdown stopped the virus in Italy

Previous studies have shown that many severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases were tied to asymptomatic carriers or those who do not manifest symptoms of the viral infection. Now, a new study reveals that in the first Italian town hit by the virus, as much as 40 percent of the population had no symptoms of the coronavirus disease (COVID-19).

Striking CryoEM image of SARS-CoV-2

A new study by researchers from the UK and Germany and published on the preprint server bioRxiv in June 2020 reports the results of a detailed study of the S protein on the intact virus, using cryoelectron microscopy (cryoEM) and tomography. This could help understand the conformation of the S protein on the virion and how it interacts with neutralizing antibodies.

Aerial undulation enhances rotational stability in flying snakes

When the paradise tree snake flies from one tall branch to another, its body ripples with waves like green cursive on a blank pad of blue sky.

Study shows how the brain's auditory system is affected by HIV

Even with effective antiretroviral therapy, patients infected with the Human Immunodeficiency Virus (HIV) sustain central nervous system damage.

Similarities between coronaviruses and human genes promote infection

A new study published on the preprint server bioRxiv* in June 2020 shows that the proportion of A/T pairing in viral genomes may increase the tendency to infect humans because of the matching molecular features in some host genes, that increases the susceptibility of the host to the virus.

New approach to analyze the perceived similarity of food products

Marina Domracheva and Sofya Kulikova, researchers from HSE University's campus in Perm, have discovered a new approach to analyse the perceived similarity of food products, based on electroencephalography (EEG) signals.

Understanding dexamethasone’s role in treating COVID-19

While the steroid medicine dexamethasone may help people with serious COVID-19 illness, it should only be given to people very ill in hospital and shouldn’t be taken by anyone to try to prevent COVID-19 or for less severe cases.

Evidence of link between ACE2 genotype and COVID-19 disease severity

A new study published on the preprint server medRxiv in June 2020 shows that variants in the ACE2 gene which encodes the enzyme receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19 disease, are linked to the risk of severe disease.

Exposure to SARS-CoV-2 can induce virus-specific T cell responses without seroconversion

A new study by researchers at Strasbourg University Hospital and published on the preprint server medRxiv* in June 2020 shows that COVID-19 antibody responses may sometimes be lacking following exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could lead to a significant underestimation of the number of infections and the number of individuals who have achieved immunity.

Computational tool provides growth rate and acceleration analysis of COVID-19 pandemic

Researchers at São Paulo State University (UNESP) in Araçatuba, Brazil, have developed a computational tool that acts like a "COVID-19 accelerometer," plotting in real time the rate at which growth is accelerating or decelerating in more than 200 countries and territories.

Using stem cells to study the developmental effects of Neandertal DNA

Protocols that allow the transformation of human induced pluripotent stem cell (iPSC) lines into organoids have changed the way scientists can study developmental processes and enable them to decipher the interplay between genes and tissue formation, particularly for organs where primary tissue is not available.
