Astronauts on the International Space Station carried out an "avoidance maneuver" Tuesday to ensure they would not be hit by a piece of debris, said US space agency NASA, urging better management of objects in Earth's orbit. Russian and US flight controllers worked together during a two-and-a-half-minute operation to adjust the station's orbit and move further away, avoiding collision.
A new study that analyzed the coronavirus outbreak in Brazil has found a link between the spread of the virus and past outbreaks of dengue fever that suggests exposure to the mosquito-transmitted illness may provide some level of immunity against Covid-19.
In a breakthrough study, researchers discovered that a blood protein test could detect the severity of head trauma in under 15 minutes.The new research was published recently in the Journal of Neurotrauma.
Scientists have developed a novel method to determine how fast the Indian Ocean is warming by analysing the sound from seabed earthquakes, an advance that may lead to a relatively low-cost technique to monitor water temperatures in all of the oceans.
The severity of Covid-19 in people with obesity and diabetes may be explained by the combined effects of the novel coronavirus and the body's natural community of bacteria -- the microbiota -- working together in the lungs, according to a new study.
The presence of antibodies indicates previous exposure to the SARS-CoV-2 virus but may not always translate into protection against the disease, say scientists, citing imponderables such as what kind of antibodies, how many and how long they last. As Covid cases mount, scientists are grappling with the pivotal issue of antibodies against the virus.
In a crucial study, the researchers have found that children can be infected with the novel coronavirus (Covid-19), but have antibodies against the disease in their blood at the same time. The study, published on Thursday in the Journal of Pediatrics, found that the virus and antibodies can coexist in young patients.
