Framing thunder: Scientists capture first ever image of boisterous bang radiating from a lightning strike


By NewsGram Staff Writer

Lightning, usually brings out scary images within the mind, thoughts of nature’s wrath being vented on the Earth. At the same time, lightning has been the object of the photographer’s affection, the beauty of its arc seducing their lusty lenses to capture the detail of the phenomenon.

Now, to take matters further, scientists have captured a picture of the sound that goes along with it, in what is touted as the first ever detailed image of thunder.

The image was captured by sending a copper wire into a cloud to make it send down thunder and lightning by Maher Dayeh, a heliophysicist from the Southwest Research Institute in San Antonio.

The event was recorded with 15 microphones that were laid out 95 meters from the lightning, which together helped capture the sound waves.

The images, which are made up of acoustic maps, are captured using a special equipment that can visualize the way that the sound moves in space.

Through the capturing of sound, scientists hope to gain a better understanding of the physics behind the natural strike.


Lightning is created by electrical charges move either within a cloud or between the cloud and the ground. It causes sudden increase in pressure and temperature which produces sudden expansion of the surrounding air, which in turn results in a sonic shock wave called thunder.

Scientists identify 36 new genes implicated in cardiac disease

  • These are the genes implicated in cardiac diseases
  • These genes play a casual but important role in the diseases of heart

Researchers have identified 36 new genes that plays a causal role in cardiac hypertrophy — abnormal thickening of the heart muscle — which can lead to heart failure.

“This is an exciting direction for personalised medicine, and also for identifying genes and therapeutic targets for complex diseases that involve many genes,” said co-author of the study Alain Karma, professor at the Northeastern University. According to the Centres for Disease Control and Prevention, one in four deaths in the US each year are due to heart disease.

“The framework described in the paper can also be used to predict whether individuals suffering from a particular disease will respond to a given drug treatment,” said lead author Marc Santolini, a postdoctoral research associate at Centre for Complex Network Research.

For the study, published in the journal npj Systems Biology, the researchers took an entirely different approach — using the Hybrid Mouse Diversity Panel, a collection of 100 genetically different strains of mice that can be used to analyse the genetic and environmental factors underlying complex traits.

Within each strain, the mice are inbred, making them all identical twins on a genetic level. Researchers took two mice from the same strain and gave one of them a stressor drug that induces heart failure. They then compared the stressed mouse’s gene expression with its non-stressed twin.

Since the mice have the same genome, they were able to pinpoint individual genes that changed expression as a direct result of the heart stressor.

Among the identified 36 such genes, many of these genes were previously unknown to be implicated in heart failure, the researcher said. They mentioned that one of them is known as a transcription factor, meaning it controls the expression of many other genes.

They confirmed the gene’s role by using molecular biology techniques to silence it and observe the resulting changes of expression.
