A Real Blast From The Past
Houston (TX) - A NASA satellite has observed a gamma-ray burst from an ancient star that died when the universe was only 630 million years old.
The event, known as GRB 090423, was the most distant cosmic explosion ever recorded.
"The Swift [satellite] was designed to catch these very distant bursts," explained Swift lead scientist Neil Gehrels. "The incredible distance to this burst exceeded our greatest expectations - it was a true blast from the past."

Under-the-Skin Blood Sugar Monitor Boosts Diabetes Control
By Steven Reinberg HealthDay Reporter
Monday, September 8, 2008; 12:00 AMMONDAY, Sept. 8 (HealthDay News) -- A device worn under the skin that measures blood sugar 24/7 can benefit people with type 1 diabetes, a new study shows.
"Continuous glucose monitoring" consists of a disposable blood sugar sensor placed under the skin, worn for a few days and then replaced. The sensor sends data to a transmitter which, in turn, sends it to a receiver worn like a pager. The receiver displays blood glucose levels on a continuous basis.
The device used in the study "monitors blood glucose about every five minutes," said lead researcher Dr. Roy W. Beck, from the Jaeb Center for Health Research in Tampa, Fla. "We evaluated how much benefit, if any, that could have on control of diabetes in both children and adults with type 1 diabetes," he said...

Solar Power Breakthrough
CAMBRIDGE, Massachusetts, August 2, 2008 (ENS) - Within 10 years, homeowners could power their homes in daylight with solar photovoltaic cells, while using excess solar energy to produce hydrogen and oxygen from water to power a household fuel cell. If the new process developed at the Massachusetts Institute of Technology finds acceptance in the marketplace, electricity-by-wire from a central source could be a thing of the past.
'This is the nirvana of what we've been talking about for years,' said MIT's Daniel Nocera, senior author of a paper describing the simple, inexpensive, and efficient process for storing solar energy in the July 31 issue of the journal 'Science.'
'Solar power has always been a limited, far-off solution. Now we can seriously think about solar power as unlimited and soon,' Nocera said..."

The height is comparable to the meat-eating tyrannosaurs. But the dinosaur, called Gigantoraptor erlianensis, also had a beak and slender legs and likely had feathers. It was 35 times larger than its likely close relation, the Caudiperyx, a small, feathered dinosaur species, Xu said.
That puts the Gigantoraptor's existence at odds with prevailing theories that dinosaurs became smaller as they evolved into birds and that bigger dinosaurs had less birdlike characteristics, he said..."

InformationWeek Weblog: The Year 2000 As Predicted In 1900: Did They Anticipate Wireless Phones And TV?
It is always interesting to see what people in the past thought "the future" would be like. Predictions usually say more about the people in the age they were made than they do about the future. But sometimes, a few of these predictions really hit home.
I came across this article from The Ladies Home Journal of December 1900 entitled, "Predictions of the Year 2000" on Andrew Sullivan's blog. While most of these predictions seem totally out of date, more than a few are not that off the mark. Take this one, for example:
Prediction #18: Telephones Around the World. Wireless telephone and
telegraph circuits will span the world. A husband in the middle of the Atlantic
will be able to converse with his wife sitting in her boudoir in Chicago. We
will be able to telephone to China quite as readily as we now talk from New York
to Brooklyn. By an automatic signal they will connect with any circuit in their
locality without the intervention of a "hello girl".

The Sun is midway through its stable hydrogen burning phase known as the main sequence. But when the Sun enters the red giant phase in around 5 billion years things are going to get a lot rougher in the Earth-Moon system.
During the red giant phase the Sun will swell until its distended atmosphere reaches out to envelop the Earth and Moon, which will both begin to be affected by gas drag-the space through which they orbit will contain more molecules.
The Moon is now moving away from Earth and by then will be in an orbit that's about 40 percent larger than today. It will be the first to warp under the Sun's influence..."

The discovery, detailed in the Dec. 22 issue of the journal Science, could be a sign of what will happen in our own solar system in a few billion years. Because the crushed asteroid was probably gravitationally lassoed in by one or more planets, the finding also provides evidence that planetary systems can form around massive stars. . ."

On Evolving
Article Tools Sponsored By
By NICHOLAS WADE
Published: December 10, 2006
A surprisingly recent instance of human evolution has been detected among the peoples of East Africa. It is the ability to digest milk in adulthood, conferred by genetic changes that occurred as recently as 3,000 years ago, a team of geneticists has found.
The finding is a striking example of a cultural practice — the raising of dairy cattle — feeding back into the human genome. It also seems to be one of the first instances of convergent human evolution to be documented at the genetic level. Convergent evolution refers to two or more populations acquiring the same trait independently.
Throughout most of human history, the ability to digest lactose, the principal sugar of milk, has been switched off after weaning because there is no further need for the lactase enzyme that breaks the sugar apart. But when cattle were first domesticated 9,000 years ago and people later started to consume their milk as well as their meat, natural selection would have favored anyone with a mutation that kept the lactase gene switched on. . ."

On. . . Everything
Genetics seems to be riding higher, but behind the display of public triumph, biology has not solved the existence of mind, and therefore the same obstacle faces both fields. An invisible world lies sealed off from investigation, leaving us to trace its footprints and echoes. MRIs and CAT scans are impressive but limited. As someone once commented, brain research is like putting a stethoscope to the outside of the Astrodome and trying to figure out the rules of football. Dawkins finds consciousness (as well as quantum physics) totally irrelevant, a comment on his own intellectual limitations rather than reality. If God is going to become viable again, he will have to be a God who solves some key mysteries in the virtual domain:
--What separates life from inert matter?
--What part does the observer play in creating reality?
--How does the infinite quantum field organize and govern every event in the universe?
--How does chaos relate to order? Are they enemies or secret allies?
--How did evolution overcome entropy, the ceaseless march of the physical universe toward chaos and the deep freezer of "heat death"?
--Why is the universe so amazingly hospitable to human life?
This last question is the most pressing one, for both believers and non-believers. . ."

An examination of rock sediments drilled from five sites at the bottom of the Atlantic Ocean strongly supports the notion that one massive hunk of space rock caused the mass extinction, a research team led by University of Missouri-Columbia geology professor Ken MacLeod found.
'It's a completely straightforward, single-impact scenario,' MacLeod, whose findings appear in the Geological Society of America Bulletin, said in an interview. 'It was a haymaker that nobody saw coming. One shot, and that's all you need to explain it.'
Scientists believe that an asteroid about 6 miles wide hurtled to Earth 65.5 million years ago at the end of the Cretaceous Period, plunging into what is now Mexico's Yucatan Peninsula to carve out the Chicxulub (pronounced CHIK-shu-loob) crater measuring about 110 miles across.
To put it mildly, it was a bad day to live on Earth."

Scientists have now levitated small live animals using sounds that are, well, uplifting.
In the past, researchers at Northwestern Polytechnical University in Xi'an, China, used ultrasound fields to successfully levitate globs of the heaviest solid and liquid—iridium and mercury, respectively. The aim of their work is to learn how to manufacture everything from pharmaceuticals to alloys without the aid of containers. At times compounds are too corrosive for containers to hold, or they react with containers in other undesirable ways."

"The weird and wonderful creatures living by methane vents in the southwest Pacific have been photographed for the first time (see images right and below).
The deep-sea communities live around methane seeps off New Zealand’s eastern coast, up to 1 kilometre beneath the sea surface. The team of 21 researchers from the US and New Zealand, who spent two weeks exploring the area, have just returned to shore. See video footage recorded by the researchers here, here and here.
“It's the first time cold seeps have been viewed and sampled in the southwest Pacific, and will greatly contribute to our knowledge of these intriguing ecosystems,” says Amy Baco-Taylor from the Woods Hole Oceanographic Institution in the US.
Cold seeps are areas of the seabed where methane or hydrogen sulphide gas escape from stores deep underneath. Like hydrothermal vents, the gases support unique life forms that can convert the energy-rich chemicals into living matter in the absence of any sunlight.
Sheer extent
Animals living around methane seeps off Chile and Japan have been observed before, but not near New Zealand. “The seeps here are remarkable in the sheer extent of their chemosynthetic communities,” says Baco-Taylor, whose team visited eight such sites between 750 and 1050 metres beneath the surface.
They used sonar to map the seafloor and to detect plumes of water rich in methane, then lowered a video and stills camera system over each site.
This allowed them to record images of tube worms between 30 cm and 40 cm in length as they emerged from beneath limestone boulders. They also recorded corals, sponges and shell beds covered with various types of clam and mussel..."

What if you could erase your memory? - The Stanford Daily Online
A recent article in The New York Times expressed concern that if the use of propanolol becomes routine, people who would not have developed PTSD will be taking the medication unnecessarily. However, neither McGaugh nor Pitman are concerned with this possibility because of the lack of serious side effects associated with the medication.
Even so, some find the manipulation of memory formation troubling.
While not wanting to appear insensitive to those suffering from PTSD, junior Erin Lashnits remarked, “I think that memories make up an important part of a person’s identity . . . even if the memories don’t change, you’re changing the intensity of that memory or of the reaction to an event. [The drug] has the potential to have much more serious complications with a person’s personality than just making life a little easier...”"

Climate Change
Submitted by BJS on Wed, 2006-11-15 13:57. energy & environment
Climate change must be taken as seriously as the issues that have traditionally monopolized first-order political attention such as conflict, poverty and the proliferation of deadly weapons, Secretary-General Kofi Annan told a United Nations conference on the issue in Nairobi today. “Instead of being economically defensive, let us start being more politically courageous,” he said. “The Nairobi conference must send a clear, credible signal that the world’s political leaders take climate change seriously. The question is not whether climate change is happening, but whether, in the face of this emergency, we ourselves can change fast enough.”"
Tribbles

Researchers at the University of Pennsylvania School of Medicine have identified a new protein associated with acute myelogenous leukemia (AML). Several lines of evidence point to a protein called Tribbles, named after the furry creatures that took over the starship Enterprise in the original 'Star Trek' series. Tribbles was first described in fruit flies."

Finding affordable ways to make technology available to everyone is a common challenge. Now, NASA has done that with the process that creates 'nanotubes.' A nanotube is a tiny, hollow, long, thin and strong tube with an outside diameter of a nanometer that is formed from atoms such as carbon. A hair from a person’s head is around 50,000 nanometers wide. If you split a hair into 50,000 strands, that would be the width of a nanometer."

Sky News: Goblins And Giants: Humans To Split
Updated: 20:39, Tuesday October 17, 2006
Social division might split humans into two sub-species 100,000 years from now, an evolution expert has claimed.
The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative.
They would be a far cry from the 'underclass' humans, who will have evolved into dim-witted, ugly, squat goblin-like creatures.
The forecast was made by Dr Oliver Curry, who spent two months investigating the ascent and descent of man over the next 100 millennia.
He said, within a thousand years, humans will evolve into coffee-coloured giants between 6 and 7ft tall.
But Dr Curry said centuries of sexual selection - being choosy about one's partner - was likely to create more and more genetic inequality.
The logical outcome would be two sub-species, 'gracile' and 'robust' humans.
Dr Curry said: 'Things could get ugly, with the possible emergence of genetic 'haves' and 'have-nots'.'"

Teleporting
CNN.com - Scientists teleport two different objects - Oct 4, 2006: 'LONDON, England (Reuters) -- Beaming people in 'Star Trek' fashion is still in the realms of science fiction, but physicists in Denmark have teleported information from light to matter bringing quantum communication and computing closer to reality.
Until now scientists have teleported similar objects such as light or single atoms over short distances from one spot to another in a split second.
But Professor Eugene Polzik and his team at the Niels Bohr Institute at Copenhagen University in Denmark have made a breakthrough by using both light and matter.
'It is one step further because for the first time it involves teleportation between light and matter, two different objects. One is the carrier of information and the other one is the storage medium,' Polzik explained in an interview on Wednesday.
The experiment involved for the first time a macroscopic atomic object containing thousands of billions of atoms. They also teleported the information a distance of half a meter but believe it can be extended further."

Junk Woes
". . . But I noticed in the recent drug survey - the same one that said baby boomers were getting high while their children say 'no' - about 6 percent of people said they had used marijuana in the past month. About 4 percent of people surveyed said they had used methamphetamine. 2.6 percent said they had abused prescription drugs. Just about 1 percent said they had used cocaine.
Heroin? Only 0.1 percent used heroin.
So why worry so much about the opium crop in Afghanistan when Americans don't really have a heroin problem? We're sacrificing the war on terror in the vain hope of one day helping Courtney Love kick her smack habit?"
Defense Tech: Area 51: Hype vs. Reality
In the October Popular Science, veteran aviation journo Bill Sweetman writes about secret airplanes he believes might be under development at the Air Force's remote Groom Lake test facility in Nevada, a.k.a. Area 51. Sweetman describes three demonstrators unveiled in recent years -- the Northrop Grumman Tacit Blue and Boeing Bird of Prey manned stealth planes and the Lockheed Martin Polecat drone -- but insists these are just consolation prizes offered up by a military that is keeping its major black airplane programs under wraps.
Not that he has a ton of proof. 'Hint[s]' and guesswork, mostly. The new construction at Groom Lake must mean something, he figures. And then there are those 'obvious... significant gaps in the military’s known aviation arsenal -- gaps that the Pentagon can reasonably be assumed to be actively, if quietly, trying to fill . . .'"
