A flash of luck helped astronomers solve a cosmic mystery: What causes powerful but fleeting radio bursts that zip and zigzag through the universe?
A group of astronomers has for the first time detected a powerful fast radio burst (FRB) coming from a source in our own Galaxy, the Milky Way, which is 30,000 light-years away.
In a significant development, scientists have identified a synthetic mini-antibody that turned out to be particularly effective in blocking the new coronavirus from entering human cells.
The research, published in the journal Physics of Fluids, found that a single 100-micrometre cough droplet under wind speed of 2 metres per second can travel up to 6.6 metres and even further under dry air conditions due to droplet evaporation. "In addition to wearing a mask, we found social distancing to be generally effective, as droplet deposition is shown to be reduced on a person who is at least 1 meter from the cough," said study author Fong Yew Leong.
Scientists have developed a vaccine candidate for COVID-19 that produces "extremely high levels" of protective antibodies in animal models, an advance that may lead to a novel therapeutic to curb the pandemic.
As astronauts celebrate the 20th anniversary of continuous human presence aboard the International Space Station (ISS) on Monday, NASA has said the orbiting laboratory has turned into a world-class facility for research which has conducted thousands of investigations from over 100 different countries.
The virus that causes Covid-19 is accumulating genetic mutations, one of which may have made it more contagious, says a study involving more than 5,000 patients in the US.
After analysing an ancient Martian meteorite, a team of Japanese researchers has revealed that water on the Red Planet originated some 4.4 billion years ago.
Rogue planets are a bit uncommon as although many of the known exoplanets discovered so far do not resemble those in our solar system, they have one thing in common -- they all orbit a star.
In the research, funded by airlines, airports and aircraft manufacturers, scientists from the Harvard T H Chan School of Public Health in the US, said the ventilation system in airplanes made of High Efficiency Particulate Air (HEPA) filters continuously circulate and refresh the air supply, "filtering out more than 99 per cent of the particles that cause COVID-19."
Many countries across the world will witness a Blue Moon tonight. The rare phenomenon coincides with Halloween, making it spookier than ever. The October 31 'Blue Moon', will be the second full moon in a month.
A study testing an experimental antibody drug for the coronavirus has been paused to investigate a possible safety issue.
NASA's Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission has successfully stowed the spacecraft's Sample Return Capsule (SRC) and its abundant sample of asteroid Bennu.
In a major study, researchers have discovered a technique that could help increase the effectiveness of vaccines against the novel coronavirus, the virus that causes Covid-19.
Elon Musk-run SpaceX is replacing two engines on its Falcon 9 rocket which is scheduled to launch four space travellers to the International Space Station on November 14.
India would launch its latest earth observation satellite EOS-01 and nine international customer spacecraft onboard its Polar rocket PSLV-C49 from the spaceport of Sriharikota in Andhra Pradesh on November 7, ISRO said on Wednesday.
A giant asteroid called Apophis, named after an Egyptian 'God of Chaos' is speeding its journey towards earth and may hit our blue planet in year 2068.
Scientists, including one of Indian-origin, have used a new mathematical method to understand airborne transmission of the novel coronavirus and found that protection from the spread of the virus increases almost proportionally with physical distancing.
NASA scientists have discovered a molecule in Saturn moon Titan's atmosphere that has never been detected in any other atmosphere. In fact, many chemists have probably barely heard of this molecule called cyclopropenylidene, or C3H2.
An analysis of more than 80 studies reporting complications experienced by COVID-19 patients has revealed that about one-third of them have abnormalities in the frontal lobe of the brain, findings which shed light on the neurological symptoms of the disease.
