Sweeps of homeless camps run counter to COVID guidance and pile on health risks

Melody Lewis lives like a nomad in the heart of downtown. Poking her head out of her green tent on a recent June day, the 57-year-old pointed a few blocks away to the place where city crews picked up her tent from a sidewalk median earlier this spring and replaced it with landscaping rocks, fencing and signs warning trespassers to keep out.

Researchers perform first X-ray measurements on SARS-CoV-2 main protease

A team of researchers at the Department of Energy's Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease -- the enzyme that enables the virus to reproduce.

Study identifies new allergy pathway

Researchers at Johns Hopkins Bloomberg School of Public Health have identified the sequence of molecular events by which tiny, tick-like creatures called house dust mites trigger asthma and allergic rhinitis.

Study finds more effective treatment for children with sickle cell anemia

A team of international researchers has learned that dose escalation of hydroxyurea treatment for children in Uganda with sickle cell anemia is more effective and has similar side effects than a lower fixed dose of the same drug.

Superbug hijacks the wound healing system to cause serious and persistent disease

Monash University researchers have discovered that the devastating bacterial superbug Clostridioides difficile hijacks the human wound healing system in order to cause serious and persistent disease, opening up the development of new therapies to treat the disease.

Structured 'cut-and-paste' design enables streamlined development of SARS-CoV-2 molecular probes

A seminal study by US researchers, currently available on the bioRxiv* preprint server, demonstrates how structure-based design can be efficiently employed to develop molecular probes targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike and its domains, with possible future use in diagnostics, treatment and vaccine development.

Sex in the time of COVID: Gay men begin to embrace a ‘new normal’

Dr. Jeffrey Klausner, a primary care physician in Los Angeles, has treated gay men for decades. Since the start of the coronavirus pandemic, he said, many patients have so dramatically changed their sexual behavior that they shrug off the need for routine screenings for sexually transmitted diseases.

USA riddled with SARS-CoV-2 - 80% undetected

The coronavirus pandemic is actively spreading across the globe, affecting 188 countries and territories. The United States remains the country with the highest number of infections. The official tally reveals that the U.S. has more than 2.347 million people infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

New study defines the transmission of COVID-19 from mother to child

UC Davis Health researchers took a critical step in defining the possible paths for the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) causing COVID-19 to get transmitted from the mother to her newborn baby. The mother to fetal transmission is known as "vertical" transmission.

Discovery provides a potential target for infectious diseases immunotherapy

NIH investigators and colleagues have discovered that when the immune system first responds to infectious agents such as viruses or bacteria, a natural brake on the response prevents overactivation.

Experts identify steps to expand, improve serology tests for COVID-19

More than 300 scientists and clinicians from the federal government, industry and academia published a report of their conclusions and recommendations on COVID-19 serology studies online in Immunity.

New dengue virus serotype DENV3 has re-emerged in Singapore after three decades

Dengue infections are rising, even as public health authorities are battling to contain the spread of the coronavirus. Dengue virus serotype 2 (DENV2) had previously been the predominant serotype but DENV3 has re-emerged in Singapore after almost three decades.

First clinical trial in South Africa for Covid-19 vaccine begins

The first clinical trial in South Africa and on the continent for a Covid-19 vaccine was announced today, 23 June 2020, at a virtual press conference hosted by the University of the Witwatersrand, Johannesburg (Wits).

Study confirms higher rates of positive COVID-19 cases in Latinx populations

In a new analysis of SARS-CoV-2, the virus that causes COVID-19, test results for nearly 38,000 people has found a positivity rate among Latinx populations about three times higher than for any other racial and ethnic group.

Prior infection provides protection against SARS-CoV-2 virus in hamsters

In an animal model for COVID-19 that shares important features of human disease, scientists at the University of Wisconsin–Madison, the University of Tokyo and the Icahn School of Medicine at Mount Sinai show that prior infection with the SARS-CoV-2 virus provides protection against reinfection, and treatment with convalescent serum limits virus replication in their lungs.
