Nanoscale magnetic imaging of ferritin in a single cell

In life sciences, the ability to measure the distribution of biomolecules inside a cell in situ is an important investigative goal. Among a variety of techniques, scientists have used magnetic imaging (MI) based on the nitrogen ...

Old life capable of revealing new tricks after all

( -- Archaea are among the oldest known life-forms, but they are not well understood. It was only in the 1970s that these single-celled microorganisms were designated as a domain of life distinct from bacteria ...

Non-line-of-sight imaging with picosecond temporal resolution

Usually, the traditional optical imaging strategies can only image the target objects within the field of camera. However, through the non-line-of-sight (NLOS) which can record the time-of-flight information about single-photon, ...

Flexible 'slinkies' form in DNA of archaea

New cryo-electron microscopy images suggest archaeal microbes pack their chromatin into tight coils that can spring open, forming unexpected contortions.

Chromosomes look different than you think

In high school textbooks, human chromosomes are pictured as wonky Xs like two hotdogs jammed together. But those images are far from accurate. "For 90 percent of the time," said Jun-Han Su, "chromosomes don't exist like that."
