Launched atop the United Launch Alliance Atlas V 401 rocket from Space Launch Complex 41 at around 3 p.m. (India time), Lucy will circle back to Earth three times for gravity assists, making it the first spacecraft to return to the vicinity of Earth from the outer solar system.

Penaloza-MacMaster collaborated with North-western Medicine physician, Igor Koralnik and Lavanya Visvabharathy, a post-doctoral research associate at Feinberg, to evaluate immune responses in humans who received Covid vaccines as well as in Covid patients. "We found that these individuals developed antibody responses that neutralised a common cold coronavirus, HCoV-OC43," Penaloza-MacMaster said. "We are now measuring how long this cross-protection lasts."

Hubble is an international cooperation between the US space agency and the European Space Agency. Astronomers at the KTH Royal Institute of Technology, Space and Plasma Physics, Sweden found that Europa harbours a vast ocean underneath its icy surface, but, mysteriously, only in one hemisphere.

There is a strong association between hermit crabs and their shelters or shells, which are taken from marine snails to protect their soft abdomens. As the hermit crab grows over the years, it will need to find a succession of larger and larger shells to replace the ones that have become too small. They can achieve this through a contest, termed a shell fight, involving the 'attacker' rapping their shell against the 'defender' in an attempt to evict the opponent from its shell.

The biomarker discovered by researchers at the DZNE and the University Medical Center Gottingen (UMG) is based on measuring levels of microRNAs -- which influence the production of proteins and thus a key process in the metabolism of every living organism. As the technique is not yet suitable for practical use, the scientists aim to develop a simple, low-cost blood test, similar to the rapid test for SARS-CoV-2, and can be applied in routine medical care to assess dementia risk.

The phase III trial conducted in 96 sites in Brazil, Czech Republic, Germany, Hungary, Italy, Japan, Mexico, Poland, Russian Federation, Spain, Ukraine, UK and US, included 903 participants who were administered a dose of 600mg of AZD7442 given by intramuscular (IM) injection.

Perseverance rover was launched on July 30 last year and arrived at the red planet on February 18 after a 203-day journey traversing 472 million kilometres. Perseverance explored the floor of Jezero Crater, which was once a lake and a dried-out river delta at the crater's edge.

The study, presented at the ANESTHESIOLOGY 2021 annual meeting, indicated that three months after cancer surgery, more than three times as many patients who did not receive dexamethasone died, compared to those who received the drug.

The Nobel laureates' discoveries have unlocked one of the secrets of nature by explaining the molecular basis for sensing heat, cold and mechanical force, which is fundamental for our ability to feel, interpret and interact with our internal and external environment.

The US space agency conducted RS-25 single-engine Retrofit-2 test series at Stennis Space Center near Bay St Louis in Mississippi on Septemeber 30, the agency said in a statement. "This successful test series for the Space Launch System RS-25 engine puts us one step closer to manufacturing the first new set of engines for future Artemis missions to the Moon," said Johnny Heflin
