Art with DNA—digitally creating 16 million colors by chemistry

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location of imperfect complementary ...

New study reveals evidence of diverse organic material on Mars

A new study featuring data from the NASA Mars Perseverance rover reports on an instrumental detection potentially consistent with organic molecules on the Martian surface, hinting toward past habitability of the Red Planet. ...

Fluorescence achieved in light-driven molecular motors

Rotary molecular motors were first created in 1999, in the laboratory of Ben Feringa, Professor of Organic Chemistry at the University of Groningen. These motors are driven by light. For many reasons, it would be good to ...

Imaging method reveals a 'symphony of cellular activities'

Within a single cell, thousands of molecules, such as proteins, ions, and other signaling molecules, work together to perform all kinds of functions—absorbing nutrients, storing memories, and differentiating into specific ...

Using sugar molecules to make cotton material glow

(Phys.org)—A team of researchers from Germany, Israel and Austria has developed a process for imbuing cotton fibers with material that glows under fluorescent light. In their paper published in the journal Science, the ...

Ultrasensitive sensor using N-doped graphene

A highly sensitive chemical sensor based on Raman spectroscopy and using nitrogen-doped graphene as a substrate was developed by an international team of researchers working at Penn State. In this case, doping refers to introducing ...
