An upcoming NASA mission could find that there are more rogue planets – planets that float in space without orbiting a sun – than there are stars in the Milky Way, a new study theorizes. “This gives us a window into these worlds that we would otherwise not have,” said Samson Johnson, an astronomy [...]

Images Description Three individuals were admitted to the hospital (ages 46–56; to men and one woman) with a multiday history of symptoms associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and underwent contrast-enhanced thoracic CT due to worsening symptomatology. Three-dimensional (3D) digital models were created to visualise the extent of the disease [...]

Study of nose and throat reveals why people with COVID-19 may lose their sense of smell Researchers studying tissue removed from patients' noses during surgery believe they may have discovered the reason why so many people with COVID-19 lose their sense of smell, even when they have no other symptoms. In their experiments they [...]

Researchers around the world are racing to develop a vaccine against Covid-19, with more than 170 candidate vaccines now tracked by the World Health Organization (WHO). Vaccines normally require years of testing and additional time to produce at scale, but scientists are hoping to develop a coronavirus vaccine within 12 to 18 months. Vaccines mimic the [...]

Rising chorus of concern over Sputnik V vaccine stems from opaque development and lack of mass-testing. In 1977 Scott Halstead, a virologist at the University of Hawaii, was studying dengue fever when he noticed a now well-known but then unexpected feature of the disease. Animals that had already been exposed to one of the [...]

Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases for the last three decades and an expert on pandemics for the last four decades, has been optimistic on a vaccine arriving at the end of 2020 or in early 2021, but he has also cautioned the public on their expectations for [...]

he United States has recorded 5 million confirmed coronavirus cases, while almost 20 million people are infected worldwide, according to Johns Hopkins University. Outside of the US, Brazil recorded more than 3 million cases, while Italy, which was ground zero of Europe's epidemic, still has one of the world's highest official death tolls at [...]

According to the first phase results, 90 per cent of the patients'lungs are still in a damaged state, which means their lungs ventilation and gas exchange functions have not recovered 90% of an example gathering of coronavirus-recuperated patients from a conspicuous medical clinic in China's Wuhan city where the pandemic broke out has detailed [...]

There are currently 25 vaccines to fight COVID-19 in clinical evaluation, another 139 vaccines in a pre-clinical stage, and many more being researched. But many of those vaccines, if they are at all successful, might not produce an immune response in portions of the population. That's because some people's bodies will react differently to the [...]

A new class of nanosensor developed in Brazil could more accurately identify dengue and Zika infections, a task that is complicated by their genetic similarities and which can result in misdiagnosis. The technique uses gold nanoparticles and can "observe" viruses at the atomic level, according to a study published in Scientific Reports. Belonging to the [...]
