Acupuncture  help patients with depression


WASHINGTON: A new study suggests that acupuncture or counselling, provided alongside usual care, could benefit patients with depression.


The study, conducted by a team led by Dr Hugh MacPherson, of the department of health sciences at the University of York, found that in a primary care setting, combining acupuncture or counselling with usual care had some benefits after three months for patients with recurring depression.

The study, which also involved researchers from the Centre for Health Economics at York and Hull York Medical School, was funded by the National Institute for Health Research (NIHR) Programme Grants for Applied Research Programme.

Many patients with depression are interested in receiving non-drug therapies, however, there is limited evidence to support the use of acupuncture or counselling for depression in a primary care setting. In this pragmatic randomised-controlled trial conducted in the north of England, the research team randomised patients with depression to receive 12 weekly sessions of acupuncture plus usual care (302 patients), or 12 weekly sessions of counselling plus usual care (302 patients), or usual care alone (151 patients).

Compared with usual care alone, there was a significant reduction in average depression scores at three months for both the acupuncture and counselling interventions, but there was no significant difference in depression scores between the acupuncture and counselling groups. At nine months and 12 months, because of improvements in the depression scores in the usual care group, acupuncture and counselling were no longer better than usual care.

The study is published in the journal PLOS Medicine.

densest galaxy known in the local universe,


Densest galaxy ever discovered


WASHINGTON: Astronomers have discovered the densest galaxy ever to be found - packed with an extraordinary number of stars - about 54 million light years from our own Milky Way.
The ultra-compact dwarf galaxy, dubbed M60-UCD1, was found in what's known as the Virgo cluster of galaxies, researchers said.
Imagine the distance between the Sun and the star nearest to it - Alpha Centauri. That's a distance of about 4 light years. Now, imagine as many as 10,000 of our Suns crammed into that relatively small space.
That is about the density of a galaxy discovered by an international team of astronomers led by a Michigan State University faculty member.
"This galaxy is more massive than any ultra-compact dwarfs of comparable size and is arguably the densest galaxy known in the local universe," said Jay Strader, MSU assistant professor of physics and astronomy.
The galaxy was discovered in the Virgo cluster of galaxies, a collection of galaxies located about 54 million light years from our own Milky Way.
What makes M60-UCD1, so remarkable is that about half of its mass is found within a radius of only about 80 light years. This would make the density of stars about 15,000 times greater than found in Earth's neighbourhood in the Milky Way.
"Travelling from one star to another would be a lot easier in M60-UCD1 than it is in our galaxy. Since the stars are so much closer in this galaxy, it would take just a fraction of the time," Strader said.
The discovery of ultra-compact galaxies is relatively new - only within the past 10 years or so. Until then, astronomers could see these "things" way off in the distance but assumed they were either single stars or very-distant galaxies.
Another intriguing aspect of this galaxy is the presence of a bright X-ray source in its centre. One explanation for this is a giant black hole weighing in at some 10 million times the mass of our Sun.

World’s first: A car driven by attention


MELBOURNE: Researchers claim to have developed the world's first attention-powered car — a pioneering vehicle that uses a headset to monitor brain activity and slow acceleration during periods of distraction.

The car commissioned by the The Royal Automobile Club of West Australia was tested in Perth in a bid to prevent road accidents due to inattention. The makers describe it as a "car that goes when you're paying attention, and slows when you're not."

The technology behind the vehicle uses a neuro headset that connects to brain activity linked to the car's engine via customized software, 'PerthNow' reported. The software communicates with the car and slows the vehicle when the driver's concentration lapses. The headset measures the electrical activity in a person's brain and feeds it into an algorithm that determines if the driver is paying attention or not.
