The possible emission rate of particle-stable tetraneutron, a four-neutron system whose existence has been long debated within the scientific community, has now been investigated. Researchers looked into tetraneutron emission from thermal fission of 235U by irradiating a sample of 88SrCO3 in a nuclear research reactor and analyzing it via -ray spectroscopy.

A research team has developed an innovative screening test. With a blood sample from the expectant mother, they can scrutinize all the genes in the fetus. The findings indicate that the new test, named desNIPT, has demonstrated effectiveness in identifying alterations in fetal genes -- a leading factor in severe congenital diseases.

A team of researchers has found that Paxlovid (Nirmatrelvir-ritonavir) did not reduce the risk of developing long COVID for vaccinated, non-hospitalized individuals during their first COVID-19 infection. They also found a higher proportion of individuals than previously reported with rebound symptoms and test-positivity after taking Paxlovid.
