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.

A team of scientists has demonstrated that communication among memory-coding neurons -- nerve cells in the brain responsible for maintaining working memory -- is disrupted with aging and that this can begin in middle age.

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.
