An improved tetravalent antibody blocks SARS-CoV-2 infection

A new study published on the preprint server bioRxiv* in June 2020 shows the potential of a new fusion molecule called a biparatopic protein to inhibit viral interaction with the host cell ACE2 receptor. This could lead to therapeutic applications.

SARS-CoV-2 mutated spike proteins show variations in cell entry

A new study by Japanese scientists published on the preprint server bioRxiv* in June 2020 shows that the D614g mutation in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein can enhance the infectivity of the virus while leaving it vulnerable to neutralization by antibodies.

Novel ACE2-antibody fusion molecules show anti-SARS-CoV-2 activity

Now, in a new study published on the preprint server, bioRxiv researchers in the U.S. investigated a soluble version of ACE2 for SARS-CoV-2 viral neutralization activity.

Beijing lockdown due to new SARS-CoV-2 cluster, New Zealand records first case in weeks

China had started to return to normalcy after successfully "flattening the curve," with the government slowly easing restrictions and opening up the economy. However, Beijing has reported new clusters of coronavirus disease (COVID-19) cases, prompting the implementation of lockdown measures.

Scientists isolate powerful SARS-CoV-2 -neutralizing antibodies from COVID-19 patients

A new study has shown that potent antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could help protect against COVID-19 infection. Preliminary results in animal studies have so far proven successful. The study titled, "Isolation of potent SARS-CoV-2 neutralizing antibodies and protection from disease in a small animal model," was published in the latest issue of the journal Science.

CSIRO study on the effects of COVID-19 on weight and well being

The CSIRO, Australia's federal government agency responsible for scientific research, has come up with a study looking at the emotional well being and weight loss or gain associated with the COVID-19 pandemic and the forced stay-at-home measures.

Antibiotic X-206 effective against SARS-CoV-2 in vitro

The current study published on the preprint server bioRxiv aims to understand how these compounds affect SARS-CoV-2 in vitro. The researchers from Aarhus University in Denmark examined 11 natural PEIs, with a single synthetic analog, screening them for inhibitory activity against the CPE of SARS-CoV-2 infecting cultured cells with overexpression of TMPRSS2, a serine protease that is instrumental in cleaving the spike protein of the virus.

Hepatitis C virus co-opts an immune protein to evade antiviral defenses

By discovering a trick the hepatitis C virus uses to evade the immune system, scientists have identified a new antiviral defense system that could be used to treat many virus infections, according to new research published today in eLife.

Study: One in five adults experienced a decrease in their sexual behavior early in the pandemic

One in five adults in the United States report they have experienced change - mostly a decrease - in their sexual behavior during the early months of the COVID-19 pandemic, according to a new study by Indiana University researchers.

How antibodies neutralize SARS-CoV-2 in convalescent patients

A new study by researchers from the United Kingdom and Taiwan and published on the preprint server bioRxiv in June 2020 describes the structural basis for the neutralizing effect of the SARS-CoV-2 antibody on the virus. This also indicates a possible therapeutic molecule by identifying its binding epitope as possibly a major neutralizing site.

TERAVOLT tracks outcomes of people with thoracic cancers affected by COVID-19

New data from TERAVOLT, a global consortium that tracks outcomes of people with thoracic cancers affected by COVID-19, offers clues as to why they experienced a high death rate of 33% when the coronavirus swept across Europe.

A new, daily home-monitoring program for patients presumed COVID-19 positive

How do you monitor patients who have COVID-19 symptoms but are not ill enough to come to the emergency department? And how do you help those patients feel cared about and less frightened while convalescing at home?

Scientists evaluate SARS-CoV-2 infection risks in livestock, poultry, pets and wildlife

A large-scale single-cell screening endeavor on a wide variety of animals showed that cells targeted by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are most abundant in cats, but are also found in other animals – unveiling a valuable resource for controlling the ongoing disruptive coronavirus disease (COVID-19) pandemic.

Researchers develop a simple tool for making mouse models of COVID-19

Until there are effective treatments or vaccines, the COVID-19 pandemic will remain a significant threat to public health and economies around the world. A major hurdle to developing and testing new anti-viral therapies and vaccines for COVID-19 is the lack of good, widely available animal models of the disease.

Key factors to "flattening the curve": Western Washington state's COVID-19 experience

Despite having the first confirmed case of coronavirus and the first major COVID-19 outbreak in the United States, the state of Washington implemented a response plan that kept its death rate the lowest among all states that have had major outbreaks.

Severity of COVID-19 linked to heparanase activity and heparan sulfate levels

Researchers at Radboud University Medical Center in the Netherlands reported an increase of heparanase activity and heparan sulfate levels in the plasma of patients with coronavirus disease (COVID-19), which was also associated with the severity of the condition – suggesting, in turn, potential treatment utility of low molecular weight heparins. The paper is currently available on the medRxiv* preprint server.

Georgia Tech professor donated 7,000 gallons of redesigned sanitizer to fight COVID-19

So many people Seth Marder spoke to didn't see the hand sanitizer crisis brewing. The country was going to run dangerously short if someone did not act urgently.

Toilet flushing can create a cloud of virus-containing aerosol droplets

Researchers used a computer simulation to show how a flushing toilet can create a cloud of virus-containing aerosol droplets that is large and widespread and lasts long enough that the droplets could be breathed in by others.
