Deep stimulation 'boosts memory'


BBC
Wed, 30 Jan 2008 15:02 UTC
Electrical stimulation of areas deep within the brain could improve memory, early research suggests.

A team of doctors in Canada stumbled upon the finding while attempting to treat a morbidly obese man through deep brain stimulation (DBS).

The electrical stimulation caused the patient to experience vivid memories.

The findings, reported in the Annals of Neurology, potentially pave the way for electrical stimulation to treat disorders such as Alzheimer's disease.

In September 2007, I was offered the role of 'Social Media Manager' at a company in Cape Town, South Africa which I took without much hesitation. I knew my job would focus on the 'general' projects such as proposals, running campaigns and devising social strategies for clients who had something they wanted to generate a buzz about online. Little did I know I would be training up the other team members completely from scratch on the subject but I can confidently say it was the most enjoyable part of the job. Here are 15 of the most important things about social media marketing I taught to those completely new to the approach.

A Nova Doesn't Create, It Destroys

Astronomers used to think that brief stellar eruptions called novae generated massive amounts of dust. But new observations of a well known nova system called RS Ophiuchus shows that isn't the case. The dust was there already, and a nova blast just clears it all away.

NASA Scientists Get First Images of Earth Flyby Asteroid

Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., have obtained the first images of asteroid 2007 TU24 using high-resolution radar data. The data indicate the asteroid is somewhat asymmetrical in shape, with a diameter roughly 250 meters (800 feet) in size. Asteroid 2007 TU24 will pass within 1.4 lunar distances, or 538,000 kilometers (334,000 miles), of Earth on Jan. 29 at 12:33 a.m. Pacific time (3:33 a.m. Eastern time).

These low-resolution radar images of asteroid 2007 TU24 were taken over a few hours by the Goldstone Solar System Radar Telescope in California's Mojave Desert. Image resolution is approximately 20-meters per pixel. Next week, the plan is to have a combination of several telescopes provide higher resolution images.

Fading black sheep cast light on evolution

Researchers have unravelled a genetic puzzle that explains why black sheep have become a dying breed on one Scottish island.

They say the findings suggest natural selection can act on single-gene traits like coat colour in a way that's more complex than generally thought.

Black death 'discriminated' between victims

The Black Death that decimated populations in Europe and elsewhere during the middle of the 14th century may not have been a blindly indiscriminate killer as previously believed.

An analysis of 490 skeletons from a London cemetery for Black Death victims shows the infection did not affect everyone equally, researchers say.

Jan. 25, 2008 -- Well water of the tiny Canadian town of Gypsumville, Manitoba (population 65) has been poisoned by an extraterrestrial.

The invader: A meteorite which struck down almost a quarter-billion years ago, creating the 25-mile-wide (40-kilometer) Lake Martin impact crater.

Asteroids Pose Greater Risk, Finds Research

Albuquerque, N.M. - An asteroid that exploded over Siberia a century ago, leaving 800 square miles of scorched or blown down trees, wasn't nearly as large as previously thought, a researcher concludes, suggesting a greater danger for Earth.

Hyperfast star proven to be alien


Carnegie Institution
Mon, 28 Jan 2008 16:33 UTC
Washington, D.C. - A young star is speeding away from the Milky Way so fast that astronomers have been puzzled by where it came from; based on its young age it has traveled too far to have come from our galaxy. Now by analyzing its velocity, light intensity, and for the first time its tell-tale elemental composition, Carnegie astronomers Alceste Bonanos and Mercedes López-Morales, and collaborators Ian Hunter and Robert Ryans from Queen's University Belfast have determined that it came from our neighboring galaxy, the Large Magellanic Cloud (LMC). The result suggests that it was ejected from that galaxy by a yet-to-be-observed massive black hole. The research will be published in an upcoming issue of the Astrophysical Journal Letters.

As vulnerable as naked mole rats seem, researchers now find the hairless, bucktoothed rodents are invulnerable to the pain of acid and the sting of chili peppers.

A better understanding of pain resistance in these sausage-like creatures could lead to new drugs for people with chronic pain, scientists added.

Even though it is sensitive to touch, the naked mole rat doesn't even flinch when inflicted with burning acid.
