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.

1. Cell therapy for melanoma The U.S. Food and Drug Administration (FDA) approved the first cellular therapy for aggressive forms of melanoma. The treatment, called Amtagvi, is "designed to fight off advanced forms of melanoma by extracting and replicating T cells derived from a patient's tumor," said NPR. These cells are also called tumor-infiltrating lymphocytes (TIL). T cells are integral in the immune system but can become "dysfunctional inside tumors." "The approval of Amtagvi represents the culmination of scientific and clinical research efforts leading to a novel T cell immunotherapy for patients with limited treatment options," Dr. Peter Marks, the director of the FDA's Center for Biologics Evaluation and Research, said in a statement. The treatment won't work for everyone, but research by the National Institutes of Health showed a "56% response rate among patients with melanoma, and 24% of patients had a complete disappearance of

  8th Edition of International Young Scientist Awards The Magic of Rainbows: Unveiling Nature's Miracles The term "rainbow" refers to a meteorological phenomenon that appears as a circular arc of multicolored light in the sky. It occurs when sunlight is refracted, or bent, by water droplets in the air, such as raindrops or mist. Rainbows typically form when there are rain showers or storms with sunlight breaking through the clouds. he colors of a rainbow are usually seen in a specific order, from top to bottom: red, orange, yellow, green, blue, indigo, and violet. This order of colors can be remembered using the acronym "ROYGBIV." Each color corresponds to a different wavelength of light, and the bending of light causes the separation and dispersion of these colors, creating the distinct rainbow pattern. Rainbows are usually seen as semicircles, with the center of the circle below the horizon. However, when observed from high altitudes, such as from an airplane

  What is climate change? A really simple guide Climate is the average weather in a place over many years. Climate change is a shift in those average conditions. The rapid climate change we are now seeing is caused by humans using oil, gas and coal for their homes, factories and transport. When these fossil fuels burn, they release greenhouse gases - mostly carbon dioxide (CO2). These gases trap the Sun's heat and cause the planet's temperature to rise. The world is now about 1.1C warmer than it was in the 19th Century - and the amount of CO2 in the atmosphere has risen by 50% Extreme weather events are already more intense across the globe, threatening lives and livelihoods. With further warming, some regions could become uninhabitable, as farmland turns into desert. East Africa just saw its fifth season of failed rains, which the UN's World Food Programme says has put up to 22 million people at risk of severe hunger. Extreme temperatures can also increase the risk of wild
