From Cosmos Magazine:

Science can help us stretch the limits of the human mind: but should we embrace brain enhancement, despite the risks?

AT THE UNIVERSITY OF CALIFORNIA in San Diego, researcher Mark Tuszynski and his colleagues have been studying the use of genetically modified neurons in the treatment of Alzheimer's disease. In 2001, the scientists implanted neurons carrying extra copies of a gene that codes for nerve growth factor, or NGF, into the brains of patients.

New Processor Will Feature 100 Cores

From Gadget Lab:

Forget dual-core and quad-core processors: A semiconductor company promises to pack 100 cores into a processor that can be used in applications that require hefty computing punch, like video conferencing, wireless base stations and networking. By comparison, Intel’s latest chips are expected to have just eight cores.

“This is a general purpose chip that can run off-the-shelf programs almost unmodified,” says Anant Agarwal, chief technical officer of Tilera, the company that is making the 100-core chip. “And we can do that while offering at least four times the compute performance of an Intel Nehalem-Ex, while burning a third of the power as a Nehalem.”

The 100-core processor, fabricated using 40-nanometer technology, is expected to be available early next year.

Getting It Wrong: Surprising Tips On How To Learn

CAN TWO WRONGS MAKE A RIGHT?: Not knowing the answer can be a good thing.
Magdalena Tworkowska

From Scientific American:

New research makes the case for hard tests, and suggests an unusual technique that anyone can use to learn.

For years, many educators have championed “errorless learning," advising teachers (and students) to create study conditions that do not permit errors. For example, a classroom teacher might drill students repeatedly on the same multiplication problem, with very little delay between the first and second presentations of the problem, ensuring that the student gets the answer correct each time.

LHC Reawakens, Sending Proton Beams Running At The Speed of Light

Recovery: Repairwork in an above-ground warehouse on the French-Swiss border Cern's damaged magnets underwent repairs at a nearby above-ground site. This man is working on the end of a dipole magnet, which contains six conductors, each of which carried 8,000 amps but were capable of conducting up to 13,000. In superconducting magnets like this one, the internal materials are kept at some of the lowest temperatures imaginable, decreasing resistance and allowing them to generate electricity with virtually no loss of heat.

What Dangers Lurk in WWII-Era Nuclear Dumps?

Marker for the first nuclear test at Los Alamos

From Discover Magazine:

Here’s one direct and obvious effect of the economic stimulus package passed in February: The toxic sites where scientists ushered in the nuclear age are getting cleaned up. In Los Alamos, New Mexico, a dump that contains refuse of the Manhattan Project and that was sealed up decades ago is finally being explored, thanks to $212 million from the American Recovery and Reinvestment Act.

But experts aren’t sure what they’ll find inside the dump. At the very least, there is probably a truck down there that was contaminated in 1945 at the Trinity test site, where the world’s first nuclear explosion seared the sky and melted the desert sand 200 miles south of here during World War II [The New York Times]. It may also contain explosive chemicals that could have become more dangerous over the years of burial.

Controversial Study Suggests Vast Magma Pool Under Washington State

From McClatchy News:

WASHINGTON -- A vast pool of molten rock in the continental crust that underlies southwestern Washington state could supply magma to three active volcanoes in the Cascade Mountains -- Mount St. Helens, Mount Rainier and Mount Adams -- according to a new study that's causing a stir among scientists.

The study, published Sunday in the magazine Nature Geoscience, concluded that the magma pool among the three mountains could be the "most widespread magma-bearing area of continental crust discovered so far."

Other scientists dismiss the existence of an underground vat of magma covering potentially hundreds of square miles as "farfetched" and "highly unlikely." Rather than magma heated to 1,300 to 1,400 degrees, some think it could be water.

From Science Daily:

Science Daily (Oct. 25, 2009) — A report examining the impact of a global biofuels program on greenhouse gas emissions during the 21st century has found that carbon loss stemming from the displacement of food crops and pastures for biofuels crops may be twice as much as the CO2 emissions from land dedicated to biofuels production. The study, led by Marine Biological Laboratory (MBL) senior scientist Jerry Melillo, also predicts that increased fertilizer use for biofuels production will cause nitrous oxide emissions (N2O) to become more important than carbon losses, in terms of warming potential, by the end of the century.

Comets Didn't Wipe Out Sabertooths, Early Americans?

North America's Great Lakes (pictured in an aerial shot on May 4, 2002) were created during glacial retreats and advances over millions of years—including the brief cold snap called the Younger Dryas, which occurred about 12,900 years ago. What caused the cold snap, though, has proved controversial: Recent research has weakened a theory that a giant comet caused the drop in temperatures and wiped out much of North America's wildlife, scientists said in October 2009.

The great bee die-off is not such a mystery after all: Industrial agriculture has stressed our pollinators to the breaking point.

It was mid-July, and Sam Comfort was teetering at the top of a 20-foot ladder, desperately trying to extract a cluster of furious honeybees from a squirrel house in rural Dutchess County, New York. Four stingers had already landed on his face, leaving welts along the fringe of his thick brown beard. That morning, the owner of the squirrel house had read an article in the local paper about Comfort’s interest in collecting feral honey­bees, so he called and invited him over. Commercial bee colonies, faced with massive mortality rates, are not faring so well these days, and unmanaged hives like this one could be their salvation. Comfort hurried over, eager to capture the hive’s queen and bring her home for monitoring and, if she fares well, breeding.

Where Will The Next Five Big Earthquakes Be?

Joseph Sohm / Visions of America / Corbis

From Time Magazine:

Earthquakes have always been part of Los Angeles' past — and its future. In 1994 a 6.7-magnitude quake hit the Northridge area of the city, badly damaging freeways, killing more than 70 people and causing $20 billion in damages. But those numbers could be dwarfed by a major quake in the future. The geologic record indicates that huge quakes occur roughly every 150 years in the region — Los Angeles lies along the southern end of the San Andreas Fault — and the last big quake, which registered a magnitude 7.9, happened in 1857. Los Angeles has done a lot to beef up its building codes and emergency response in the 15 years since the Northridge quake and may be better prepared than any other major American city, but the city's sheer size ensures the next Big One will be bloody.

Spencer: AGW Has Most Of The Characteristics Of An “Urban Legend”

Urban legend? Gators don't really live in the sewer.

From Watts Up With That?

About.com describes an “urban legend” as an apocryphal (of questionable authenticity), secondhand story, told as true and just plausible enough to be believed, about some horrific…series of events….it’s likely to be framed as a cautionary tale. Whether factual or not, an urban legend is meant to be believed. In lieu of evidence, however, the teller of an urban legend is apt to rely on skillful storytelling and reference to putatively trustworthy sources.

I contend that the belief in human-caused global warming as a dangerous event, either now or in the future, has most of the characteristics of an urban legend. Like other urban legends, it is based upon an element of truth. Carbon dioxide is a greenhouse gas whose concentration in the atmosphere is increasing, and since greenhouse gases warm the lower atmosphere, more CO2 can be expected, at least theoretically, to result in some level of warming.

NASA Ares Rocket Development To Take Too Long

From Future Pundit:

An article in New Scientist about the NASA Ares rocket program reports that a White House advisory panel chaired by former Lockheed Martin CEO Norman Augustine recommends against further development of the Ares rocket because it will take too long to develop.

The rocket is set to make its first test flight on 27 October. But the committee believes the rocket will not be ready to loft crew to orbit until 2017, two years after the ISS is scheduled to be abandoned and hurled into the Pacific Ocean, Augustine said. Extending use of the space station to 2020 would not make much difference, since this would eat up funds available for Ares I and delay its first flight to 2018 or 2019, added committee member Edward Crawley of MIT.

From Live Science:

When it comes to metabolism, size matters—cell size, that is, according to a recent study.

Small animals have faster metabolisms relative to their body size than do large animals. According to the so-called metabolic theory of ecology, that scaling is responsible for many patterns in nature—from the average lifespan of a single species to the population dynamics of an entire ecosystem. Although scientists generally agree on the theory's fundamentals, they disagree on the reasons for the scaling. One camp thinks metabolic rate is driven by cell size; another thinks it corresponds to the size and geometry of physiological supply networks, such as the circulatory system.
