First planet to orbit 3 stars discovered
Unlike our solar system, which consists of a solitary star, it is believed that half of all star systems, like GW Ori where astronomers observed the novel phenomenon, consist of two or more stars that are gravitationally bound to each other. However, until now no planet orbiting three stars -- a circumptriple orbit -- has ever been discovered.
Gene in monkeys, mice may act as antiviral to block HIV, Ebola
The gene, called retroCHMP3, encodes an altered protein that disrupts the ability of certain viruses to exit an infected cell and prevents it from going on to infect other cells.
37% infected patients diagnosed with at least one long-Covid symptom: Study
According to researchers, including Paul Harrison from the University of Oxford, the most common symptoms were breathing problems, abdominal symptoms, fatigue, pain and anxiety/depression. "Research of different kinds is urgently needed to understand why not everyone recovers rapidly and fully from Covid-19. We need to identify the mechanisms underlying the diverse symptoms that can affect survivors," Harrison.
Large-scale reactor producing hydrogen developed by Indian researchers
India has set a target of 450 GW of renewable energy by 2030. To achieve this, researchers are working towards renewable energy solutions, which should be sustainable with a limited carbon footprint.
Sun block: NASA's Mars missions will halt communication
The period, called Mars solar conjunction, happens every two years. This year it falls between October 2 and October 16. While the missions on the Red Planet will continue collecting data, engineers back on Earth will stop sending commands to them until October 16, the agency said in a statement on Tuesday. The Sun expels hot, ionised gas from its corona, which extends far into space.
A gas station on Red Planet? New CO2 reactor can make Martian fuel
Researchers at the University of Cincinnati used a carbon catalyst in a reactor to convert carbon dioxide into methane. Known as the "Sabatier reaction" from the late French chemist Paul Sabatier, it's a process the International Space Station uses to scrub the carbon dioxide from air the astronauts breathe and generate rocket fuel to keep the station in high orbit.
Hubble's new 'molten Einstein ring' image prompts new research
The object, GAL-CLUS-022058s, is located in the southern hemisphere constellation of Fornax (the Furnace). The image was nicknamed the "Molten Ring", which alludes to its appearance and host constellation.
'Quite terrifying': Closest known relatives of Covid virus found in Laos
The study, posted on the preprint server Research Square and not peer-reviewed yet, showed that the similarity of parts of the new viruses' genetic code with SARS-CoV-2 reinforces claims that Covid-19 has a natural origin. At the same time, their discovery means there are numerous coronaviruses with the potential to infect people, Nature reported.
Covid might be occasional trigger for Guillain-Barre syndrome
In the disorder, a person's immune system attacks the nerves, causing muscle weakness and occasionally, paralysis. The condition is triggered by an acute bacterial or viral infection and can last for weeks or several years. Since the beginning of the pandemic, doctors have reported over 90 GBS cases following a possible Covid-19 infection.
Astronomers find why galaxies become dormant
Star formation is one of the key ways that galaxies grow, and they're said to have gone quiescent when they cease forming stars. Using NASA's Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile, the team from the University of Massachusetts, Amherst detected six such massive galaxies that were dead.
