"First Contact With Inner Earth": Drillers Strike Magma

A collapsed vent allows hot lava to peek through solidified rock at Hawaii's Kilauea volcano in an undated photo. For the first time on record, workers drilling at a geothermal plant near Kilauea accidentally hit a pocket of magma in its natural environment deep inside Earth. Announcing the find at a December 2008 meeting, one volcano expert likened the discovery to a paleontologist finding a dinosaur romping on a remote island.

From National Geographic:

A drilling crew recently cracked through rock layers deep beneath Hawaii and accidentally became the first humans known to have drilled into magma—the melted form of rock that sometimes erupts to the surface as lava—in its natural environment, scientists announced this week.

"This is an unprecedented discovery," said Bruce Marsh, a volcanologist from Johns Hopkins University in Maryland, who will be studying the find.

Normally, he said, volcanologists have to do "postmortem studies" of long-solidified magmas or study active lava during volcanic eruptions.

But this time they'd found magma in its natural environment—something Marsh described as nearly as exciting as a paleontologist finding a dinosaur frolicking on a remote island.

"This is my Jurassic Park," he said at a meeting of the American Geophysical Union meeting in San Francisco.

Earth's Original Ancestor Was LUCA, Not Adam Nor Eve

From E! Science News:

Here's another argument against intelligent design. An evolutionary geneticist from the Université de Montréal, together with researchers from the French cities of Lyon and Montpellier, have published a ground-breaking study that characterizes the common ancestor of all life on earth, LUCA (Last Universal Common Ancestor). Their findings, presented in a recent issue of Nature, show that the 3.8-billion-year-old organism was not the creature usually imagined. The study changes ideas of early life on Earth. "It is generally believed that LUCA was a heat-loving or hyperthermophilic organism. A bit like one of those weird organisms living in the hot vents along the continental ridges deep in the oceans today (above 90 degrees Celsius)," says Nicolas Lartillot, the study's co-author and a bio-informatics professor at the Université de Montréal. "However, our data suggests that LUCA was actually sensitive to warmer temperatures and lived in a climate below 50 degrees."

From Science Daily:

ScienceDaily (Dec. 17, 2008) — A team of astronomers led by John Johnson of the University of Hawaii's Institute for Astronomy has used a new technique to measure the precise size of a planet around a distant star. They used a camera so sensitive that it could detect the passage of a moth in front of a lit window from a distance of 1,000 miles.

The camera, mounted on the UH 2.2-meter telescope on Mauna Kea, measures the small decrease in brightness that occurs when a planet passes in front of its star along the line-of-sight from Earth. These "planet transits" allow researchers to measure the diameters of worlds outside our solar system.

Want A Retired Space Shuttle? They're Up For Grabs

From Yahoo News/AP:

CAPE CANAVERAL, Fla. – NASA's soon-to-be-retired space shuttles are up for grabs. The space agency said Wednesday it's looking for ideas on where and how best to display its space shuttles once they stop flying in a few years. It's put out a call to schools, science museums and "other appropriate organizations" that might be interested in showcasing one of the three remaining shuttles.

Beware: NASA estimates it will cost about $42 million to get each shuttle ready and get it where it needs to go, and the final tab could end up much more.

Bright Future: LEDs Revolutionize Lighting

LEDs (light emitting diodes) are similar to regular light bulbs but have no filament. Their light is generated by electrons moving through a semiconductor material. They produce more light, less heat, and consume less energy than other types of lighting. Credit: NIST

From Live Science:

You might have noticed energy-efficient LED lights replacing the traditional holiday bulb lights on many store shelves this year. They're not cheap, but the sales pitch is they save energy, cut the risk of fire and last practically forever.

By all accounts, LED lighting has a very bright future, and the future is arriving rapidly as utility companies tout the benefits of LEDs, and individuals and businesses make the switch both for environmental reasons and to save money.

From Popular Mechanics:

New research from DARPA could open the door to on-demand blood-cell manufacturing on battlefields and in hospitals. All medics need is a machine that uses a nanofiber that mimics bone marrow to turn a handful of stem cells into gallons of blood. Who needs blood donations when you have blood pharming?

Fresher blood is better than stale: It carries more oxygen and, when transfused into patients, speeds recovery. Military medics are all too familiar with this problem in the field, where donated blood may take two or more weeks to reach soldiers who need it immediately. But medical researchers—also known as blood pharmers—are working on manufacturing the red stuff on the spot.

Aging Brains Allow Negative Memories To Fade

From E! Science News:

It turns out there's a scientific reason why older people tend to see the past through rose-coloured glasses. A University of Alberta medical researcher, in collaboration with colleagues at Duke University, identified brain activity that causes older adults to remember fewer negative events than their younger counterparts.

"Seniors actually use their brain differently than younger people when it comes to storing memory, especially if that memory is a negative one," said study author Dr. Florin Dolcos, an assistant professor of psychiatry and neuroscience in the Faculty of Medicine & Dentistry.

The study, published online in December in the U.S.-based journal Psychological Science, found age-related changes in brain activity when participants with an average age of 70 where shown standardiz

Earth’s Magnetic Field Has Massive Breach - Scientists Baffled

(Click To Enlarge)

Watts Up With That:

I know. This sounds like a plot of a 1950’s scifi movie. But it is real. From my view, our localized corner of the solar system is now different than it used to be and changes in the magnetic interactions are evident everywhere. First we have the interplanetary magnetic field that took an abrupt dive in October 2005 and has not recovered since and remains at very low level:

Then we have the recent discovery that the ionosphere has dropped in altitude to unexpected and unexplained low levels.

We have a solar cycle 24 (driven by the solar magnetic dynamo) which can’t seem to get out of the starting gate, being a year late with forecasts for activity from it being revised again and again.

From Live Science:

Scientists have found two large leaks in Earth's magnetosphere, the region around our planet that shields us from severe solar storms.

The leaks are defying many of scientists' previous ideas on how the interaction between Earth's magnetosphere and solar wind occurs: The leaks are in an unexpected location, let in solar particles in faster than expected and the whole interaction works in a manner that is completely the opposite of what scientists had thought.

The findings have implications for how solar storms affect the our planet. Serious storms, which involved charged particles spewing from the sun, can disable satellites and even disrupt power grids on Earth.

From Yahoo News/AP:

WASHINGTON – More than 2 trillion tons of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming.

More than half of the loss of landlocked ice in the past five years has occurred in Greenland, based on measurements of ice weight by NASA's GRACE satellite, said NASA geophysicist Scott Luthcke. The water melting from Greenland in the past five years would fill up about 11 Chesapeake Bays, he said, and the Greenland melt seems to be accelerating.

NASA scientists planned to present their findings Thursday at the American Geophysical Union conference in San Francisco. Luthcke said Greenland figures for the summer of 2008 aren't complete yet, but this year's ice loss, while still significant, won't be as severe as 2007.

Can Nuclear Power Compete?

From Science America:

Newly approved reactor designs could reduce global warming and fossil-fuel dependence, but utilities are grappling with whether better nukes make market sense

On an August afternoon in Washington, D.C., typically miserable for its heat, humidity and stillness, reporters gathered at a downtown hotel not known for its air-conditioning. Stuffed inside a windowless conference room that was being heated still further by the television people’s lights, we waited for Michael J. Wallace, who had been trying, in fits and starts, to unveil nuclear power’s second act.

On arrival, Wallace, a meticulous manager not known for ad-libbing, looked out over the sweating reporters and smiled. “It’s days like today that highlight the real need for new, emissions-free, baseload power,” he said. Unless we get started soon, he added, rolling blackouts could become the norm.

'Death Map' Shows Heat A Big Hazard To Americans

From Reuters:

WASHINGTON, Dec 16 (Reuters) - Heat is more likely to kill an American than an earthquake, and thunderstorms kill more people than hurricanes do, according to a U.S. "death map" published on Tuesday.

Researchers who compiled the county-by-county look at what natural disasters kill Americans said they hope their study will help emergency preparedness officials plan better.

Heat and drought caused 19.6 percent of total deaths from natural hazards, with summer thunderstorms causing 18.8 percent and winter weather causing 18.1 percent, the team at the University of South Carolina found.

Earthquakes, wildfires and hurricanes combined were responsible for fewer than 5 percent of all hazard deaths.

Writing in BioMed Central's International Journal of Health Geographics, they said they hoped to dispel some myths about what the biggest threats to life and limb are.

"According to our results, the answer is heat," Susan Cutter and Kevin Borden of the University of South Carolina wrote in their report, which gathered data from 1970 to 2004.

From NPR:

Plummeting gasoline and diesel prices have given consumers relief at the pump. But oil pessimists believe the current slump in demand will pass. And when it does, the world will be in the same fix it was before the global recession. The era of easy oil is behind us. According to those who believe in what's called "peak oil theory," world oil production has already peaked, or flattened, and in the foreseeable future, the declining resource will inevitably change the way we live.

Google Says It Still Stands By Net Neutrality

From Yahoo Finance/AP:

Google denies Wall Street Journal claim that it's giving up on `Net neutrality'

NEW YORK (AP) -- Google Inc. denied that it had reversed its stance on the issue of "Net neutrality" and dismissed a story in Monday's edition of The Wall Street Journal on the subject as "confused."

Citing undisclosed sources, the newspaper reported that Google had been in talks with major cable and phone companies about getting preferential treatment for traffic to and from its sites.

That would conflict with the principle of Net neutrality, under which carriers traditionally give the same treatment to traffic from different sites. The Federal Communications Commission has voiced support for the principle, and sanctioned Comcast Corp. this year for slowing some types of file-sharing traffic. Google has been a vocal supporter of Net neutrality.

Google Wants Its Own Fast Track On The Web

From The Wall Street Journal:

The celebrated openness of the Internet -- network providers are not supposed to give preferential treatment to any traffic -- is quietly losing powerful defenders.

Google Inc. has approached major cable and phone companies that carry Internet traffic with a proposal to create a fast lane for its own content, according to documents reviewed by The Wall Street Journal. Google has traditionally been one of the loudest advocates of equal network access for all content providers.

At risk is a principle known as network neutrality: Cable and phone companies that operate the data pipelines are supposed to treat all traffic the same -- nobody is supposed to jump the line.

But phone and cable companies argue that Internet content providers should share in their network costs, particularly with Internet traffic growing by more than 50% annually, according to estimates. Carriers say that to keep up with surging traffic, driven mainly by the proliferation of online video, they need to boost revenue to upgrade their networks. Charging companies for fast lanes is one option.

Doctor's Advice: Leave the Toilet Seat Up

From Live Science:

One of the longest-running spousal debates may now be settled in favor of men and for the sake of little boys.

Leave the toilet seat up, some British doctors now say. The reason: a rising trend for heavy wooden and ornamental toilet seats to fall down onto the penises of unsuspecting (and just potty-trained) toddlers.

Dr. Joe Philip and his colleagues of Leighton Hospital, Crewe, in England detail such penis-crush injuries in the December issue of the journal BJU International. The team reports on four boys between the ages of 2 and 4 who were admitted to hospitals with injuries serious enough to require an overnight stay.
