Scientists Listen to Faint Sounds Inside Insects

17.05.2010
A team of Clarkson University scientists led by Prof. Igor Sokolov are using atomic force microscopy (AFM) to record sounds emanating from inside living insects like flies, mosquitoes and ladybugs.

AFM is one of major scientific tools responsible for the emergence of modern nanotechnology.

The unprecedented sensitivity of AFM allowed the Clarkson team to record sub-nano oscillations of very faint amplitude (less than the size of one atom) at high frequencies (up to 1,000 hertz or cycles per second). Previous work in the study of insects was only done at up to 5 hertz. The sounds are recorded by touching the surface of the bugs with an AFM probe.

The study of these sounds may allow researchers to discover unknown features and physiology of insects. Sokolov hopes these discoveries may help in finding solutions to the problems caused by insect pests.

"Insects are of general interest not only as the most numerous and diverse group of animals on the planet, but also as highly efficient bio-machines varying greatly in size," says Sokolov. "Some are major agricultural pests and competitors of humans for crops. Mosquitoes and other insects are important vectors of plant, animal, and human diseases. Also, vast lands of the earth are still underdeveloped because they are occupied by blood-sucking insects."

You can listen to audio files of the internal sounds of mosquitoes, flies, and ladybugs at: http://ftp.aip.org/epaps/appl_phys_lett/E-APPLAB-96-038950 .

The Sokolov team's research is published in the top journal of applied physics, Applied Physics Letters, at http://apl.aip.org/applab/v96/i4/p043701_s1 .

The team consisted of Sokolov, who has appointments in Physics, and Chemistry and Biomolecular Science; Maxim Dokukin, a physics postdoctoral fellow; and Nataliia Guz, a physics graduate student; and Sergey Vasilyev, instrumental scientist. The other members of Sokolov’s group, physics graduate students Dmytro Volkov, Ravi Gaikwad, and Shyuzhene Li, work on biosensors, self-assembly of particles, and the study of skin aging.

Their research was performed within the Nanoengineering and Biotechnology Laboratories Center (NABLAB), a unit established to promote cross-disciplinary collaborations within the University and led by Sokolov. It comprises more than a dozen faculty members to capitalize on the expertise of Clarkson scholars in the areas of cancer cell research, fine particles for bio and medical applications, synthesis of smart materials, advancement biosensors, etc.

Clarkson University launches leaders into the global economy. One in six alumni already leads as a CEO, VP or equivalent senior executive of a company. Located just outside the Adirondack Park in Potsdam, N.Y., Clarkson is a nationally recognized research university for undergraduates with select graduate programs in signature areas of academic excellence directed toward the world’s pressing issues. Through 50 rigorous programs of study in engineering, business, arts, sciences and health sciences, the entire learning-living community spans boundaries across disciplines, nations and cultures to build powers of observation, challenge the status quo, and connect discovery and engineering innovation with enterprise.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
