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.
London, USA, September 7, 2017: Treating young people who suffer from insomnia by using online cognitive behavioral therapy (CBT) could reduce debilitating mental health problems such as anxiety and depression, scientists said Wednesday.
In a large trial published in The Lancet Psychiatry journal, researchers at Oxford University’s Sleep and Circadian Neuroscience Institute also found that successfully treating sleep disruption eased psychotic symptoms such as hallucinations and paranoia.
“Sleep problems are very common in people with mental health disorders, but for too long insomnia has been trivialized as merely a symptom, rather than a cause, of psychological difficulties,” said Daniel Freeman, a professor of clinical psychology who led the work.
“This study turns that old idea on its head, showing that insomnia may actually be a contributory cause of mental health problems.”
The research involved 3,755 university students from across Britain who were randomized into two groups. One group had six sessions of online CBT, each lasting about 20 minutes, and delivered via a digital program called Sleepio. The others had access to standard treatments but no CBT.
Freeman’s team monitored participants’ mental health with a series of online questionnaires at zero, three, 10 and 22 weeks from the start of treatment.
The researchers found that those who had the CBT sleep treatment reduced their insomnia significantly as well as showing small but sustained reductions in paranoia and hallucinatory experiences.
The CBT also led to improvements in depression, anxiety, nightmares, psychological well-being, and daytime work and home functioning.
Andrew Welchman, head of neuroscience and mental health at the Wellcome Trust health charity, which helped fund the research, said the results suggested improving sleep may provide a promising route into early treatment to improve mental health.
Freeman added: “A good night’s sleep really can make a difference to people’s psychological health. Helping people get better sleep could be an important first step in tackling many psychological problems and emotional problems.” (VOA)
Etomidate was invented by scientists from Janssen Pharmaceuticals
The reason behind conviction of Mark Asay last year was that in 1988 he racially motivated killing of 2 men in Jacksonville, Florida
Before he shot Booker, he called him a racial epithet
Florida (USA), August 25, 2017: A 53-year-old convict Mark Asay was executed using a new drug called Etomidate for lethal injection on 24 August 2017. This drug has not been used before in the US.
Mark Asay was executed reportedly and one of the three drugs used for lethal injection was etomidate. It’s the first time that in execution they used the drug etomidate.
Earlier midazolam was used for executions but now it is harder to get this drug as some drug manufacturers didn’t want it to be used for executions. Now, Etomidate is a substitution for midazolam.
According to CNN report, Greg Panico, spokesman for the company said, “Etomidate, an intravenous anesthetic, was invented by scientists from Janssen Pharmaceuticals in the 1960s
According to WJAX report, “This month, the Florida Supreme Court rejected arguments from Mark Asay’s attorneys that the new drug would cause too much pain.” Florida’s highest court said that the inmate Mark Asay had not shown that it would result in more pain and dismissed a motion to block the execution.
The reason behind conviction of Mark Asay last year was that in 1988 he racially motivated killing of 2 men in Jacksonville, Florida.
The two men whom the jury found him guilty of murdering were Robert Lee Booker, who was black and Robert McDowell. “Before he shot Booker, he called him a racial epithet. Prosecutors say he killed McDowell, who was dressed as a woman, after saying he would pay him for sex,” mentions WJAX report.
“The execution marks Florida’s first since The US Supreme Court ruling temporarily halted the practice in early 2016, saying the state’s sentencing process was unconstitutional because it gave judges, rather than juries, too much power in deciding whether to execute an inmate,” mentions CNN report.
On 24 August 2017, US Supreme Court denied a stay for execution request in Asay’s case and it was scheduled that he would die by injection after 6 p.m. EST. It was also revealed that Asay didn’t have any pending petitions along with the Florida Supreme Court.
In 1979, the death penalty was reinstituted by the state and since then, Mark James Asay is the first white man to be sentenced for the death penalty in Florida for killing a black man.

The up-close beauty of our solar system’s biggest planetary storm is being revealed by NASA spacecraft
Juno flew directly over Jupiter’s Great Red Spot, passing an amazingly close 5,600 miles (9,000 kilometers) above the monster storm
Swirling clouds are clearly visible in the 10,000-mile-wide (16,000-kilometer-wide) storm, which is big enough to swallow Earth and has been around for centuries
Cape Canaveral, California, July 14, 2017: A NASA spacecraft circling Jupiter is revealing the up-close beauty of our solar system’s biggest planetary storm.
Juno flew directly over Jupiter’s Great Red Spot on Monday, passing an amazingly close 5,600 miles (9,000 kilometers) above the monster storm. The images snapped by JunoCam were beamed back Tuesday and posted online Wednesday. Then members of the public — so-called citizen scientists — were encouraged to enhance the raw images.
Swirling clouds are clearly visible in the 10,000-mile-wide (16,000-kilometer-wide) storm, which is big enough to swallow Earth and has been around for centuries.
“For hundreds of years scientists have been observing, wondering and theorizing about Jupiter’s Great Red Spot,” said lead researcher Scott Bolton of the Southwest Research Institute in San Antonio. “Now we have the best pictures ever of this iconic storm.”
Information was still arriving Thursday from Juno’s science instruments. Bolton said it will take the time to analyze everything to shed “new light on the past, present, and future of the Great Red Spot.”
Juno’s next close encounter with the giant gas planet will be in September. The Great Red Spot won’t be in Juno’s scopes then, however.
Launched in 2011, Juno arrived at Jupiter last July. It is only the second spacecraft to orbit the solar system’s largest planet, but is passing much closer than NASA’s Galileo did from 1995 through 2003. (VOA)
