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)

Scientists Track ‘Ghost Particle’ to Source for First Time

Scientists have announced a new finding about the source of a high-energy neutrino, a subatomic particle detected at an observatory at the Earth’s South Pole.

The study, published Thursday in the journal Science, details the work of more than 1,000 scientists who pooled their research on the tiny particles, which are able to pass through matter in a straight line — like a ghost.

The neutrino’s ability to travel without deviation from its course means its source can be accurately tracked, unlike other types of subatomic particles that can be dragged off course by a magnetic field like the Earth’s.

“[Neutrinos are] very clean, they have simple interactions, and that means every single neutrino interaction tells you something,” said Heidi Schellman, a particle physicist at Oregon State University.

The scientists used a large observatory known as IceCube, in use since 2010, to hunt for neutrinos and try to track the source. A group of neutrinos coming from the same location over the past couple of years was determined to have emanated from a blazar, or black hole that aims a jet of radiation at Earth. The black hole is estimated to have been in a distant galaxy that destructed four billion years ago.

The blazar that is considered the source of the neutrino was named TXS 0506+056 and is believed to be the first known source of a high-energy neutrino.

The discovery could be a breakthrough for multimessenger astronomy, where scientists look at the entire electromagnetic spectrum and pool their findings, using known relationships between types of electromagnetic particles to put together a larger picture.

“It is an entirely new means for us to learn about the cosmos,” Roopesh Ojha of NASA’s Goddard Space Flight Center told The Washington Post. (VOA)
