From Live Science:

Researchers have made an advance toward a long-sought goal of building "invisible electronics" and transparent displays.

The work could eventually lead to better heads-up displays for pilots or even windshield displays and cars, as well as electronic paper that could deliver all the contents of a magazine or a newspaper on one, ever-changing, portable and perhaps even disposable sheet. Another goal: wearable electronic clothing displays.

The scientists, led by Chongwu Zhou and colleagues at UCLA developed tiny, transparent electronic circuits they say are more powerful than similar devices developed in recent years.

The work was detailed in the Jan. 27 issue of ACS Nano, a monthly journal.

In the new study, Chongwu Zhou and colleagues point out that although scientists have previously developed nano-sized transparent circuits, previous versions are limited to a handful of materials that are transparent semiconductors.

Kissing Feels So Pleasurable Due To Hormone Surge, Find Scientists

From The Telegraph:

The reason that kissing feels so pleasurable is that sparks a surge of hormones in our brains, according to new research.

Couples who share a passionate kiss this Valentine's Day will enjoy sensations of relaxation and excitement because of a complex series of chemical processes, as well as their love for their partners.

The study showed that women need more than just a kiss to experience the same chemical high as men - with additional features such as a romantic atmosphere of dimmed lights and mood music also required.

Wendy Hill, professor of psychology at Lafayette College, Pennsylvania began the research to find out why the mundane physical activity of rubbing lips can elicit such a gratifying emotional response.

Her team tested the levels of two hormones, cortisol and oxytocin, in 15 couples before and after holding hands and kissing.

They found that kissing reduced the levels of cortisol, a stress hormone, in both sexes. But levels of oxytocin, a hormone linked to social bonding that they expected to be boosted by kissing, only rose among the men.

From The Guardian:

Breakthroughs in microscopic engineering could boost shelf life of food and increase crop yields.

A controversial scientific revolution that could give packaged foods a dramatically longer shelf life and boost crop growth has "real potential" to help feed a fast-growing world, according to environment secretary Hilary Benn.

New developments in nanotechnology, engineering carried out at a microscopic level, could lead to plastic packaging designed to stop food and drink spoiling by killing bacteria or preventing oxygen getting through the container.

The technology could also be used to enrich food with supplements and preserve vitamins that would otherwise be destroyed as food aged. Farmers could also use it to ensure the slow release of fertilisers at the right time for crops, and to detect threats from pests or pollutants. The technology is, however, highly controversial, with green campaigners arguing that its effects on human health are unknown.

The Look Of Love? Women Are Attracted To Men With Big Pupils, Says Study

Was Jennifer Aniston's character Beth in the film He's Just Not That Into You attracted to her boyfriend Neil, played by Ben Affleck, because of his big pupils?

From The Daily Mail:

Researchers have discovered what women are really thinking when they look into a man’s eyes – and it is all about the size of their...pupils.

Women become attracted to men with large pupils just as they are approaching their most fertile time of the month, the study at Edinburgh University found.

Scientists suggest that it may be because it indicates that the man is sexually interested in them and available for mating. Pupil size made no significant difference for the rest of the menstrual cycle.

Global Warming Studies Often Depend On Average Citizens

Photo: From Care Global Warming.

From McClatchy:

WASHINGTON — It has to do with brown-headed cowbirds and clear-cut forests, lilacs and wildfires, vineyards in the Rhine Valley, marmots, dandelions, tadpoles, cherry trees around the Tidal Basin in Washington and musty old records stuffed in shoe boxes in people's closets and stacked on museum shelves.

As scientists track global warming, they're using sometimes centuries-old data to assess its impact on plants, animals, insects, fish, reptiles and amphibians. Increasingly, they're discovering that it can take only one seemingly insignificant change to disrupt an entire ecosystem.

"People talk about a 1- or 2-degree rise in temperature and it's inconsequential to us. Who cares?" said Greg Jones, an environmental studies professor at Southern Oregon University who's been studying wine grapes. "But in an ecosystem it can have dramatic effects."

From The Christian Science Monitor:

From Minnesota to Texas, wind power sweeps new jobs into old-tech towns.

Cedar Rapids and Estherville, Iowa

Hundreds of workers lost their jobs after the Rockwell-Goss printing press factory closed here in Cedar Rapids in 2001. The hulking empty shell sat idle on the outskirts of the city for four years.

But that was before wind power blew into town, bringing thousands of clean-tech manufacturing jobs to Iowa and the Midwest.

In many cases, the new industry is setting up shop in defunct heavy manufacturing plants, bringing new economic life and vitality to old settings.

Bob Loyd, who once oversaw crews manufacturing the last printing presses to leave the old Rockwell-Goss factory, now manages workers assembling the newest generation of giant wind turbines in the same building.

Curing Baldness Could Be A Step To Organ Regeneration

Deep roots. For a hair follicle to begin a new phase of growth, an elusive group of cells called the hair germ (bright red) must be activated. This progression of images shows that the hair germ begins proliferating (green) before other cells do, suggesting a two-step mechanism.

From The Next Big Future:

Research from Rockefeller University reveals that a structure at the base of each strand of hair, the hair follicle, uses a two-step mechanism to activate its stem cells and order them to divide. The mechanism provides insights into how repositories of stem cells may be organized in other body tissues for the purpose of supporting organ regeneration.

So understanding and fixing the stem cells and the replenishment of stem cells in hair follicles could lead to a baldness cure and also to human regeneration of organs.

Large Hadron Collider To Be Re-Started Later This Year

At Cern, the Large Hadron Collider could recreate conditions that last prevailed when the universe was less than a trillionth of a second old. Above is one of the collider's massive particle detectors, called the Compact Muon Solenoid. Valerio Mezzanotti for The New York Times

From The Telegraph:

Scientists are expected to make a decision within days on when the Large Hadron Collider, the broken "Big Bang" machine, will be re-started.

The LHC suffered a catastrophic malfunction soon after being switched on last September amid a fanfare of publicity.

Officials and scientists from the European Organization for Nuclear Research (CERN), which built the £4billion device, have been in talks this week about when to re-start it.

They have also discussed what caused the LHC to grind to a halt and how to prevent similar incidents happening in the future.

CERN have now said that they hope the machine will be up and running in time to deliver the first batch of data for experts to begin experiments by the end of the year.

A final decision on the exact date to switch it back on is expected following a meeting on Monday.

Leading scientists met last night to debate whether genetically modified crops can feed the world's hungry. The issue, it seems, is as divisive as ever

The Science Museum in London is running an exhibition until the end of May called Future Foods. It attempts to give a balanced view of the pros and cons of genetically modified crops, which are back on the agenda in the light of fears over a major food crisis. It does a good job too.

As part of the exhibition, the museum organised a debate at the Dana Centre to give the public a chance to debate GM crops and the food crisis with some key scientists. I chaired the event and picked up on a few issues I thought might be worth sharing.

Study: How Money Can Buy Happiness

From Live Science:

You've heard many times that money can't buy happiness. That probably never stopped you from shopping. But a new study suggests you might want to spend more on doing things and less on stuff.

Buying life experiences rather than material possessions leads to greater happiness for both the consumer and those around them, researchers announced today at the annual meeting of the Society for Personality and Social Psychology.

A meal out or tickets to the theater result in increased well-being because they satisfy higher order needs, specifically the need for social connectedness and vitality — a feeling of being alive, the researchers say.

"These findings support an extension of basic need theory, where purchases that increase psychological need satisfaction will produce the greatest well-being," said Ryan Howell, assistant professor of psychology at San Francisco State University.

"Noah's Flood" Not Rooted In Reality, After All?

Some believe that Noah's Ark came to rest on Turkey's Mount Ararat, above. But the ancient flood that some scientists think gave rise to the Noah story may not have been quite so biblical in proportion, a January 2009 study says. Photograph by Melik Baghdasaryan/AP/Photolur

From National Geographic:

The ancient flood that some scientists think gave rise to the Noah story may not have been quite so biblical in proportion, a new study says.

Researchers generally agree that, during a warming period about 9,400 years ago, an onrush of seawater from the Mediterranean spurred a connection with the Black Sea, then a largely freshwater lake. That flood turned the lake into a rapidly rising sea.

A previous theory said the Black Sea rose up to 195 feet (60 meters), possibly burying villages and spawning the tale of Noah's flood and other inundation folklore.

But the new study—largely focused on relatively undisturbed underwater fossils—suggests a rise of no more than 30 feet (10 meters).

The entire genome of a 38,000-year-old Neanderthal has been sequenced by a team of scientists in Germany. The group is already extracting DNA from other ancient Neanderthal bones and hopes that the genomes will allow an unprecedented comparison between modern humans and their closest evolutionary relative.

The three-year project, which cost about €5 million (US$6.4 million), was carried out at the Max Planck Institute for Evolutionary Anthropology in Leipzig. Project leader Svante Pääbo will announce the results of the preliminary genomic analysis at the American Association for the Advancement of Science annual meeting in Chicago, Illinois, which starts on 12 February.

Are We Bringing Our Germs to Mars?

From Time Magazine:

Star Trek fans know it as the Prime Directive: that there should be no interference with the internal affairs of other civilizations. (Given the frequency with which captains Kirk, Picard, et. al., violate it, however, the Prime Directive seems more like a Prime Suggestion.) Since human beings have yet to explore very far beyond Earth, pondering an interplanetary noninterference policy of our own may seem a little premature — at least until we've mastered warp drives and phasers.

But in fact, such a directive already exists in some form — the international Outer Space Treaty of 1967, which governs the legal framework for activities in space. Best known for banning governments from putting nuclear weapons into orbit, the treaty also requires space-faring nations to avoid "harmful contamination" of other worlds while exploring the solar system. Human beings have yet to set foot on other planets, so the risk today comes from bacteria that can hitch a ride on unmanned spacecraft like NASA's Mars Phoenix Lander, which arrived on the red planet's surface last May.

TED: Change The World With $100,000

From CBS News:

CBS Technology correspondent Daniel Sieberg is reporting from the TED conference in Long Beach, Calif.

The concept is simple; it's the execution that requires global collaboration and commitment. Not to mention some serious cash. Along those lines, TED prizes are an award of $100,000 given to a select group of recipients looking to change the world with one idea or "wish." They can use the money as they choose, and at a ceremony here Thursday night the three winners expressed their hopes for the future.

Jill Tarter, founder of SETI or the Search for Extra-Terrestrial Life, encouraged TED attendees and others to imagine ways that every "earthling" could contribute to a growing database of life beyond our planet or our "cosmic company." In real terms, Tarter wants kids to be more involved in the experience of searching or studying the universe, and improve the way information from space is stored and shared with astronomers. Her announcement was preceded by a taped introduction from Sir Richard Branson, who is actively pursuing commercial space travel through his Virgin Galactic project.

Top 5 Most Extreme Exoplanets

From Wired Science:

Searching for planets beyond our solar system is a bit like playing Goldilocks — we keep looking for that one that will be just right to host life. While astronomers haven't found a perfect fit yet, they have found plenty that are too big, too hot, too cold, too dense, too close to their star, or too distant.

The first exoplanet discovery was in 1988, though it was controversial at the time and wasn't officially confirmed until 2003. Over the years, more than 330 extrasolar planets have been found, nearly all of them using indirect methods such as detecting the wobble of a star due to the gravitational pull of an orbiting planet or the slight dimming of the star's light as a planet passes in front of it.

Key Insights Into How New Species Emerge

From Science Digest:

ScienceDaily (Feb. 6, 2009) — A team of researchers are reporting the ongoing emergence of a new species of fruit fly--and the sequential development of a new species of wasp--in the February 6 issue of the journal Science.

Jeff Feder, a University of Notre Dame biologist, and his colleagues say the introduction of apples to America almost 400 years ago ultimately may have changed the behavior of a fruit fly, leading to its modification and the subsequent modification of a parasitic wasp that feeds on it.

The result is a chain reaction of biodiversity where the modification of one species triggers the sequential modification of a second, dependent species.

"It's a nice demonstration of how the initial speciation of one organism opens up an opportunity for another species in the ecosystem to speciate in kind," said Feder. "Biodiversity in essence is the source for new biodiversity."

Reading This Will Change Your Brain

Jeff Sherman / Taxi-Getty Images

From Newsweek:

A leading neuroscientist says processing digital information can rewire your circuits. But is it evolution?

Is technology changing our brains? A new study by UCLA neuroscientist Gary Small adds to a growing body of research that says it is. And according to Small's new book, "iBRAIN: Surviving the Technological Alteration of the Modern Mind," a dramatic shift in how we gather information and communicate with one another has touched off an era of rapid evolution that may ultimately change the human brain as we know it. "Perhaps not since early man first discovered how to use a tool has the human brain been affected so quickly and so dramatically," he writes. "As the brain evolves and shifts its focus towards new technological skills, it drifts away from fundamental social skills."

How You Can Tell A Person's Class: The Wealthy Fidget, Yawn And Generally Appear Rude, Say Researchers

Photo: Body language: Those from wealthier backgrounds tend to appear more distracted than their less well off counterparts

From The Daily Mail:

Fidgeting, yawning and doodling have long been equated with boredom.

But if the person you're speaking to isn't paying attention, they may be rich rather than rude, a study has revealed.

It found that posh people fidget more - making it possible to tell a person's social class by their body language.

Researchers said those born into privilege may feel less of a need to make a good impression and so are more inclined to fidget when talking to other people.

In contrast, their poorer counterparts are anxious to make a good impression and so are more attentive.

From China View:

SHANGHAI, Feb.1 (Xinhua) -- East Asian astronomers are building the world's largest radio telescope array to see the deep into the galaxy and black holes and more accurately determine the orbits of lunar probes such as China's Chang'e-1.

The array, called the East Asia Very Long Baseline Interferometry (VLBI) consortium, consists of 19 radio telescopes from China, Japan and the Republic of Korea (ROK) that cover an area with a diameter of 6,000 kilometers from northern Japan's Hokkaido to western China's Kunming and Urumqi.

The VLBI technology is widely used in radio astronomy. It combines the observations simultaneously made by several telescopes to expand the diameter and increase magnification.

US Wind Power Grew By 50% In 2008 As China's Doubled

Vail Resorts said Tuesday that it would buy credits for wind power like that generated by the turbines at the Gray County Wind Farm in Kansas. Orlin Wagner/Associated Press (New York Times)

From Ars Technica:

The Global Wind Energy Council, an industry group, has totaled the past year's growth in generating capacity, and found that wind had a very good year, with US wind power having its highest annual growth ever, and China doubling its installed capacity.

Many renewable energy technologies, most notably photovoltaic, are struggling to reach what's called "grid parity," where the cost of the power they generate matches that of fossil fuel generation. One technology that's largely there is wind, as maturing turbine technology and economies of scale have made the economics of wind power quite competitive. Those economics can clearly be seen in the latest figures on the growth of the wind industry, which cover 2008. Among the milestones: wind was the largest component of Europe's growth in electric generating capacity, the US became the world's top wind energy producer, and China doubled its installed capacity in just a year—for the fourth year running.

Oldest Fossil Evidence for Animals Found

From Live Science:

The oldest fossilized evidence of animals has been unearthed in Oman and reveals that tiny sea sponges were abundant 635 million years ago, long before most of the planet's other major animal groups evolved, according to a new analysis.

This early life hardly looked like us, but some of the so-called demosponges can be sizable today. Demosponges still make up 90 percent of all sponges on Earth and 100 percent of Earth's largest sponges, including barrel sponges, which can be larger than an old-style phone booth.

The ancient demosponges — probably measuring across no more than the width of a fork tine — were pinned down via fossilized steroids, called steranes, which are characteristic of the cell membranes of the sponges, rather than via direct fossils of the sponges themselves.

The Father Factor: How Dad's Age Increases Baby's Risk of Mental Illness

When a large study linked schizophrenia to paternal age, some researchers wondered if the root cause, rather than age, was that men who had waited had the makings of the disease themselves. Getty Images

From Scientific American:

Could becoming a father after age 40 raise the risks that your children will have a mental illness?

* It is widely recognized that a 40-year-old woman has an increased risk of bearing a child with Down syndrome. What is not known is that a 40-year-old man has the same risk of fathering a child with schizophrenia—and even higher odds of his offspring having autism. The risk of bipolar disorder appears to rise as well.
* In the past couple of decades, the number of older fathers has increased. Birth rates for men older than 40 have jumped as much as 40 percent since 1980.
* The mechanisms behind the higher risks are still being investigated, although scientists have several hypotheses that could someday lead to better therapies or possibly even cures for these mental illnesses.

When my wife, Elizabeth, was pregnant, she had a routine ultrasound exam, and I was astonished by the images. The baby’s ears, his tiny lips, the lenses of his eyes and even the feathery, fluttering valves in his heart were as crisp and clear as the muscles and tendons in a Leonardo da Vinci drawing. Months before he was born, we were already squabbling about whom he looked like. Mostly, though, we were relieved; everything seemed to be fine.

Intelligent Life Could Be Thriving On 40,000 Planets

This planet, located near the centre of the Milky Way about 20,000 light years from us, is just one of the 40,000 which could be harbouring intelligent life

From Daily Mail:

Science’s quest to discover life on Mars has so far failed to find even one little green man.

But not to worry. Aliens could be alive and well on almost 40,000 other planets.

Researchers have calculated that up to 37,964 worlds in our galaxy are hospitable enough to be home to creatures at least as intelligent as ourselves.

Astrophysicist Duncan Forgan created a computer programme that collated all the data on the 330 or so planets known to man and worked out what proportion would have conditions suitable for life.

The estimate, which took into account factors such as temperature and availability of water and minerals, was then extrapolated across the Milky Way.

Three scenarios of how life could develop were also taken into account.

Five Years of Facebook: A Retrospective

From PC World:

It doesn't seem like five years since Facebook appeared on the scene. I was slow to join the throng--my friends list numbers only 242 of the 110 million people who have joined the site since its inception.

Facebook is less juvenile in look-and-feel than MySpace, which it has overtaken in popularity. It is also a lot cleaner, again in look-and-feel but also in content. It also lacks the sexual content that plagues MySpace.

Facebook is more generalist in approach than some other social networking sites, such as Linked-In, which seem aimed at people looking for jobs and customers instead of communicating with people they already know. If you want to exploit your friends, Linked-In seems an excellent place to do it. And they'll exploit you in return.

New, Free Software Enables You To Keep Tabs On Others' Whereabouts, And Vice Versa, Using Cell Phones, Says Natali Del Conte

(CBS) Google is releasing free software Wednesday that enables people to keep track of each other using their cell phones.

CNET got a sneak peek at it, and CNET-TV Senior Editor and Early Show contributor Natali Del Conte explained how it works on the show Tuesday.

She says "Latitude" uses GPS systems and what's called cell tower triangulation to do the job. The software seeks the closest three cell towers and, with GPS, combines the data to show where someone is.

It is designed to work on any phone with Internet capabilities, except the iPhone.

"Latitude" is being marketed as a tool that could help parents keep tabs on their children's locations, but it can be used for anyone to find anyone else, assuming permission is given.

Timing of Seasons Is Changing

Image from Businessweek

From Live Science:

The Earth's seasons have shifted back in the calendar year, with the hottest and coldest days of the years now occurring almost two days earlier, a new study finds.

This shift could be the work of global warming, the researchers say.

To figure this out, scientists at the University of California, Berkeley and Harvard studied temperature data from 1850 to 2007 compiled by the University of East Anglia's Climate Research Unit in the United Kingdom.

They found that temperatures over land in the 100-year period between 1850 and 1950 showed a simple, natural pattern of variability, with the hottest day of the year in the Northern Hemisphere landing around July 21. But from the mid-1950s onward (the period when global average temperatures began to rise), the hottest day came 1.7 days earlier.

From Yahoo News/Space.com:

NASA has delayed the planned Feb. 12 launch of the space shuttle Discovery by least a week to allow extra time to evaluate vital fuel valves on the spacecraft, agency officials said late Tuesday.

Discovery was slated to launch toward the International Space Station on Feb. 12 to deliver the last set of U.S.-built solar arrays to the orbiting laboratory. The mission is now scheduled to blast off no earlier than Feb. 19 at about 4:41 a.m. EST (0941 GMT), but an official launch target will be determined at a later date.

"By looking at it right now, we think it's about a week delay, but we're not going to put pressure on the team," said John Shannon, NASA's space shuttle program manager, in a briefing at the agency's Kennedy Space Center in Florida. "We'll just let the information drive us."

Astronomers Discover Link Between Supermassive Black Holes And Galaxy Formation

Two giant elliptical galaxies, NGC 4621 and NGC 4472, look similar from a distance, as seen on the right in images from the Sloan Digital Sky Survey. But zooming into these galaxies' cores with Hubble Space Telescope reveals their differences (left, black and white images). NGC 4621 shows a bright core, while NGC 4472 is much dimmer. The core of this galaxy is populated with fewer stars. Many stars have been slung out of the core when the galaxy collided and merged with another. Their two supermassive black holes orbited each other, and their great gravity sent stars careening out of the galaxy's core. (Credit: NASA/AURA/STScI and WikiSky/SDSS)

From Science Daily:

ScienceDaily (Feb. 3, 2009) — A pair of astronomers from Texas and Germany have used a telescope at The University of Texas at Austin's McDonald Observatory together with Hubble Space Telescope and many other telescopes around the world to uncover new evidence that the largest, most massive galaxies in the universe and the supermassive black holes at their hearts grew together over time.

"They evolved in lockstep," said The University of Texas at Austin's John Kormendy, who co-authored the research with Ralf Bender of Germany's Max-Planck-Institute for Extraterrestrial Physics and Ludwig Maximilians University Observatory. The results are puiblished in this week's issue of Astrophysical Journal Letters.

From Scientific American:

LONDON (Reuters) - The United States overtook Germany as the biggest producer of wind power last year, new figures showed, and will likely take the lead in solar power this year, analysts said on Monday.

Even before an expected "Obama bounce" from a new President who has vowed to boost clean energy, U.S. wind power capacity surged 50 percent last year to 25 gigwatts (GW) -- enough to power more than five million homes.

Political and business leaders worldwide have urged "green growth" spending on clean energy to fight both recession and climate change.

German wind power capacity reached nearly 24 GW, placing it second ahead of Spain and fourth-placed China, which doubled its installed wind power for the forth year running, said the Brussels-based Global Wind Energy Council.

New .tel Domain Names Set To Create The World's Virtual Phone Book

From The Independent:

Millions of new internet addresses are put up for sale today, giving the public the chance to insert their entry into the world’s largest phone book.

The new “.tel” domain names go up for grabs this afternoon. Unlike other website addresses, however, they are not meant to act as catchy names for websites but rather to become people’s individual entries in a universal virtual directory.

Companies and individuals are being encouraged to list their phone numbers, websites, postal addresses, e-mail addresses and even their Facebook details in their .tel entry.

“.tel is your place on the internet, which will act like a switchboard.” said Kash Mahdavi, the chief executive of Telnic, the London-based company that runs the .tel registry. “You can say, ‘Here are my Facebook details, here is my mobile number, and people will always be able to find you’.”

Dean Kamen: Part Man, Part Machine -- The Telegraph

Some see Dean Kamen as a Willy Wonka character whose most famous invention - the Segway personal transporter - is still the butt of jokes. Others compare him to Henry Ford. His next project, after perfecting an electric car, is to 'to fix the world' - using a 200-year-old engine nobody else thinks can work. By Adam Higginbotham

Ten years ago, on the summit of a hill in the verdant New England countryside, at the highest point he could find between Boston and Manchester, New Hampshire, Dean Kamen designed and built the sprawling, hexagonal house he called Westwind.

From The Guardian:

Corn-based bioethanol has higher burden on environment and human health, says US study

Some biofuels cause more health problems than petrol and diesel, according to scientists who have calculated the health costs associated with different types of fuel.

The study shows that corn-based bioethanol, which is produced extensively in the US, has a higher combined environmental and health burden than conventional fuels. However, there are high hopes for the next generation of biofuels, which can be made from organic waste or plants grown on marginal land that is not used to grow foods. They have less than half the combined health and environmental costs of standard gasoline and a third of current biofuels.

Smallest Exoplanet Is Most Earth-like Yet

From Wired News:

The smallest exoplanet ever seen is less than twice the size of Earth, and orbits a star similar to our sun. Astronomers recently spotted this world, the most Earth-like planet yet discovered, with the COROT satellite.

"For the first time, we have unambiguously detected a planet that is 'rocky' in the same sense as our own Earth,” said Malcolm Fridlund, ESA COROT project scientist.

For all its similarity to our own globe, though, it is still a far cry away from a habitable Earth-twin. For one thing, it is so hot — between 1,830 and 2,730 degrees Fahrenheit — that scientists think it might be covered in lava. It orbits extremely close to its sun and whips around the star once every 20 hours.

When Dreams Come True

From Science News:

People interpret dreams in ways that affect their waking lives, especially when those dreams support pre-existing beliefs

Dreams don’t just bubble up at night and then evaporate like morning dew once the sun rises. What you dream shapes what you think about your upcoming plans and your closest confidants, especially if nighttime reveries fit with what’s already convenient to believe, a new report finds.

In an effort to understand whether people take their dreams seriously, Carey Morewedge of Carnegie Mellon University in Pittsburgh and Michael Norton of Harvard University surveyed 149 college students attending universities in India, South Korea or the United States about theories of dream function.

People across cultures often assume that dreams contain hidden truths, much as Sigmund Freud posited more than a century ago, Morewedge and Norton report in the February Journal of Personality and Social Psychology. In fact, many individuals consider dreams to provide more meaningful information regarding daily affairs than comparable waking thoughts do, the two psychologists conclude.

Windows 7: Better Late Than Never

Larry Magid Says Windows 7 Is What Vista Should Have Been

(CBS) I don't know why it took so long, but Microsoft has finally fixed Vista. Only it isn't calling it Vista. Instead the company is working on what it's calling a new version of Windows -- Windows 7. The operating system isn't commercially available but is likely to be out by the end of the year.

I don't know how much Microsoft plans to charge for the upgrade once it's officially available, but they should give it away free to anyone who bought Vista or a PC with Vista preinstalled. Even though there are some new features, Windows 7 strikes me mostly as a bug fix. It speeds up Windows and fixes one of its most annoying "features" and makes one particularly useful change to the user interface. It seems to me that anyone who paid for Vista is entitled to this upgrade.

From The New York Times:

Sea explorers probing the depths of the English Channel have discovered what they say is a legendary British warship that sank in a fierce storm in 1744, losing more than 900 men and possibly four tons of gold coins that could be worth $1 billion.

The team found the wreckage of the warship, the H.M.S. Victory, last year and confirmed its identity through a close examination of 41 bronze cannons visible on the sandy bottom, Gregory P. Stemm, head of the discovery team, said Monday at a news conference in London.

The team lifted two of the cannons from the seabed and gave them to the British Defense Ministry, he said. The team’s leaders are now negotiating with British authorities on the disposition of the artifacts and treasure before the divers attempt further recoveries.

Nuclear Fusion Fission Hybrid Reactor To Destroy Waste

Photo from ABC News (Australia)

From Future Pundit:

The idea behind long term (tens or hundreds of thousands of years) nuclear waste storage facilities is that we can't solve the nuclear waste disposal problem quickly. But matter is so manipulable in the hands of sufficiently smart scientists and technologists that sometimes supposedly insolvable problems become solvable. UT Austin researchers think they know how to convert nuclear power plant waste into far safer elements with a hybrid reactor.

AUSTIN, Texas--Physicists at The University of Texas at Austin have designed a new system that, when fully developed, would use fusion to eliminate most of the transuranic waste produced by nuclear power plants.

From Science Daily:

ScienceDaily (Feb. 2, 2009) — Over 14,000 years ago during the last Pleistocene Ice Age, when a large part of the European continent was covered in ice and snow, Neanderthals in the region of Gibraltar in the south of the Iberian peninsula were able to survive because of the refugium of plant and animal biodiversity. Today, plant fossil remains discovered in Gorham's Cave confirm this unique diversity and wealth of resources available in this area of the planet.

The international team jointly led by Spanish researchers has reconstructed the landscape near Gorham's Cave in Gibraltar, by means of paleobotanical data (plant fossil records) located in the geological deposits investigated between 1997 and 2004. The study, which is published in the Quaternary Science Reviews, also re-examines previous findings relating to the glacial refugia for trees during the ice age in the Iberian Peninsula.

From Live Science:

The federal government has approved the first study by a company that will use human embryonic stem cells injected into a human.

The Geron corporation announce the approval today. The therapy used in the study is designed to treat spinal cord injuries by injecting stem cells — which are able to transform into the many different types of cells we need in our bodies — directly into the patients' spinal cords.

The U.S. Food and Drug Administration (FDA) granted clearance of the company's application for the clinical trial of GRNOPC1 in patients with acute spinal cord injury.

"This marks the beginning of what is potentially a new chapter in medical therapeutics - one that reaches beyond pills to a new level of healing: the restoration of organ and tissue function achieved by the injection of healthy replacement cells," said Geron's president and CEO. Dr. Thomas B. Okarma.

Japan Warns Of Volcano Eruption Within 48 Hours

Japan' has warned the Mount Asama volcano could erupt within 48 hours Photo: Reuters

From The Telegraph:

Tens of thousands of people living near Japan's volatile Mount Asama have been told to brace themselves for a major volcanic eruption within 48 hours.

The volcano is one of Japan's most active and last erupted in September 2004 when molten rock and ash blanketed areas more than 125 miles from the crater.

Even by Japanese standards, Mount Asama is an active volcano, with frequent bouts of activity over recent years. The most famous eruption came in 1783 and caused the deaths of more than 1,500 people and widespread damage.

Japan's Meteorological Agency yesterday raised the alert level for the 8,420ft peak, warning of an imminent eruption and forbidding anyone to scale the mountain.

More than 45,000 nearby residents have been put on alert and told to be ready to leave their homes within two hours notice.
