Scientists have successfully trapped atoms of krypton (Kr), a noble gas, inside a carbon nanotube to form a one-dimensional gas. Scientists used advanced transmission electron microscopy (TEM) methods to capture the moment when Kr atoms joined together, one by one, inside a 'nano test tube' container with diameter half a million times smaller than the width of a human hair.

Scientists have revealed that low-frequency ultrasound influences blood parameters. The findings suggest that ultrasound's effect on haemoglobin can improve oxygen's transfer from the lungs to bodily tissues. The research was undertaken on 300 blood samples collected from 42 pulmonary patients.

Scientists have grown 'mini-placentas' in the lab and used them to shed light on how the placenta develops and interacts with the inner lining of the womb -- findings that could help scientists better understand and, in future, potentially treat pre-eclampsia. The study shows that it is possible to experiment on a developing human placenta, rather than merely observe specimens, in order to study major disorders of pregnancy.

A new study reported that SARS-CoV-2, the virus that causes COVID, can infect dopamine neurons in the brain and trigger senescence -- when a cell loses the ability to grow and divide. The researchers suggest that further research on this finding may shed light on the neurological symptoms associated with long COVID such as brain fog, lethargy and depression.

A new study suggests the moments that follow a distressing episode are more memorable than the moments leading up to it. The results add to our understanding of how trauma impacts memory and may improve how we evaluate eyewitness testimonies, treat PTSD, and combat memory decline in brain disorders like Alzheimer's disease.
