The world’s fastest microscope makes its debut





The motion of whizzing electrons has been captured like never before.

Researchers have developed a laser-based microscope that snaps images at attosecond — or a billionth of a billionth of a second — speed. Dubbed “attomicroscopy,” the technique can capture the zippy motion of electrons inside a molecule with much greater precision than previously possible, physicist Mohammed Hassan and colleagues report August 21 in Science Advances.

“I always try to see the things nobody’s seen before,” says Hassan, of the University of Arizona in Tucson.




The attomicroscope is a modified transmission electron microscope, which uses a beam of electrons to image things as small as a few nanometers across (SN: 7/16/08). Like light, electrons can be thought of as waves. These wavelengths, though, are much smaller than those of light. That means an electron beam has a higher resolution than a conventional laser and can detect smaller things, like atoms or clouds of other electrons.



To get their superfast images, Hassan and colleagues used a laser to chop the electron beam into ultrashort pulses. Like the shutter on a camera, those pulses allowed them to capture a new image of the electrons in a sheet of graphene every 625 attoseconds — roughly a thousand times as fast as existing techniques.



The microscope can’t capture images of a single electron yet — that would require extremely high spatial resolution. But by stringing the collected images together, scientists created a kind of stop-motion movie that shows how a collection of electrons move through a molecule.

The technique could let researchers watch how a chemical reaction occurs or probe how electrons move through DNA, Hassan says. That information could help scientists craft new materials or personalized medicines.


The world’s fastest microscope has officially made its debut, revolutionizing the field of microscopy with unprecedented speed and precision. This cutting-edge technology allows scientists to observe and record cellular processes in real-time, providing insights at a level of detail never before possible. The breakthrough is expected to accelerate research in various fields, including biology, medicine, and materials science, by enabling faster and more accurate analysis of complex systems.

Nano-patterned copper oxide sensor provides rapid ultra-low hydrogen detection

Image
Hydrogen is becoming an increasingly popular choice as we shift towards cleaner energy. It can be burned like traditional fuels, producing only water as a byproduct, and can generate electricity when used in fuel cells. However, as hydrogen production, use, and transportation increase, so do safety concerns. Hydrogen is highly flammable at concentrations as low as 4% and is odorless and colorless, making leaks challenging to detect.

Nature’s first fiber optics could light the way to internet innovation

Image
In a discovery that blurs the line between biology and technology, scientists have found that heart-shaped clams use fiber optic–like structures to channel sunlight through their shells in much the same way that telecommunications company use fiber optics to deliver high-speed internet connectivity into homes. This innovation, a first known example of bundled fiber optics in a living creature, helps to explain how heart cockles (Corculum cardissa) — a marine bivalve found in shallow waters across the Indian and Pacific Oceans — harness sunlight to nourish symbiotic algae living within, while protecting them from harmful ultraviolet rays. In return, the algae provide the clams with sugars and other essential nutrients. The finding highlights an evolutionary adaptation that parallels human technological ingenuity, and offers potential insights for the development of bioinspired optical systems in the future, researchers report November 19 in Nature Communications. Heart cockles are sm...
