>Experimental Xerox Paper Erases Itself, Results In Temporary Documents On Reusable Paper

>

Xerox Corporation scientists have invented a way to make prints whose images last only a day, so that the paper can be used again and again. The technology, which is still in a preliminary state, blurs the line between paper documents and digital displays and could ultimately lead to a significant reduction in paper use.

The experimental printing technology, a collaboration between the Xerox Research Centre of Canada and PARC (Palo Alto Research Center Inc.), could someday replace printed pages that are used for just a brief time before being discarded. Xerox estimates that as many as two out of every five pages printed in the office are for what it calls “daily” use, like e-mails, Web pages and reference materials that have been printed for a single viewing.

“Despite our reliance on computers to share and process information, there is still a strong dependence on the printed page for reading and absorbing content. Of course, we’d all like to use less paper, but we know from talking with customers that many people still prefer to work with information on paper. Self-erasing documents for short-term use offers the best of both worlds,” said Paul Smith, manager of XRCC’s new materials design and synthesis lab.

Xerox has filed for patents on the technology, which it calls “erasable paper.” It is currently part of a laboratory project that focuses on the concept of future dynamic documents.

To develop erasable paper, researchers needed to identify ways to create temporary images. The “a-ha” moment came from developing compounds that change color when they absorb a certain wavelength of light but then will gradually disappear. In its present version, the paper self-erases in about 16-24 hours and can be used multiple times.

While scientists at XRCC work on the chemistry of the technology, their counterparts at PARC – the birthplace of the laser printer – are investigating ways to build a device that could write the image onto the special paper. PARC researchers developed a prototype “printer” that creates the image on the paper using a light bar that provides a specific wavelength of light as a writing source. The written image fades naturally over time or can be immediately erased by exposing it to heat.

While potential users have shown interest in transient documents, there is still much to be done if the technology is to be commercialized. “This will remain a research project for some time,” said Eric Shrader, PARC area manager, industrial inkjet systems. “Our experiments prove that it can be done, and that is the first step, but not the only one, to developing a system that is commercially viable.”

Temporary documents are part of Xerox’s ongoing investments in sustainable innovation – or “green products” – that deliver measurable benefits to the environment, such as solid ink printing technology, which generates 90 percent less waste than comparable laser printers; more energy-efficient printers, copiers and multifunction devices; and other paper-saving innovations. – xerox

>Tips for Handling Telemarketers

>

Three Little Words That Work!!

(1)The three little words are: ‘Hold On, Please…’

Saying this, while putting down your phone and walking off (instead of hanging-up immediately) would make each telemarketing call so much more time-consuming that boiler room sales would grind to a halt.
< BR>Then when you eventually hear the phone company’s ‘beep-beep-beep’ tone, you know it’s time to go back and hang up your handset, which has efficiently completed its task.

These three little words will help eliminate telephone soliciting.

(2) Do you ever get those annoying phone calls with no one on the other end?
This is a telemarketing technique where a machine makes phone calls and records the time of day when a person answers the phone.

This technique is used to determine the best time of day for a ‘real’sales person to call back and get someone at home.

What you can do after answering, if you notice there is no one there, is to immediately start hitting your # button on the phone, 6 or 7 times, as quickly as possible. This confuses the machine that dialed the call and it kicks your number out of their system. Gosh, what a shame not to have your name in their system any longer!!!

(3) Junk Mail Help:
When you get ‘ads’ enclosed with your phone or utility bill, return these ‘ads’ with your payment. Let the sending companies throw their own junk mail away.

When you get those ‘p re-approved’ letters in the mail for everything from credit cards to 2nd mortgages and similar type junk, do not throw away the return envelope.

Most of these come with postage-paid return envelopes, right? It costs them more than the regular 50 cents postage ‘IF’ and when they receive them back.

It costs them nothing if you throw them away! The postage was around 50 cents before the last increase and it is according to the weight. In that case, why not get rid of some of your other junk mail and put it in these cool little, postage-paid return envelopes.

One of Andy Rooney’s (60 minutes) ideas.
Send an ad for your local chimney cleaner to American Express. Send a pizza coupon to Citibank. If you didn’t get anything else that day, then just send them their blank application back!
If you want to remain anonymous, just make sure your name isn’t on anything you send them.

You can even send the envelope back empty if you want to just to keep them guessing! It still costs them 50 cents.

The banks and credit card companies are currently getting a lot of their own junk back in the mail, but folks, we need to OVERWHELM them. Let’s let them know what it’s like to get lots of junk mail, and best of all, they’re paying for it…Twice!

Let’s help keep our postal service busy since they are saying that e-mail is cutting into their business profits, and that’s why they need to increase postage costs again. You get the idea !

If enough people follow these tips, it will work —- I have been doing this for years, and I get very little junk mail anymore.  – via email.

>Legless Lizard And Tiny Woodpecker Among New Species Discovered In Brazil

>

Researchers discovered a legless lizard and a tiny woodpecker along with 12 other suspected new species in Brazil’s Cerrado, one of the world’s 34 biodiversity conservation hotspots.

The Cerrado’s wooded grassland once covered an area half the size of Europe, but is now being converted to cropland and ranchland at twice the rate of the neighboring Amazon rainforest, resulting in the loss of native vegetation and unique species.

An expedition comprising scientists from Conservation International (CI) and Brazilian universities found 14 species believed new to science — eight fish, three reptiles, one amphibian, one mammal, and one bird — in and around the Serra Geral do Tocantins Ecological Station, a 716,000-hectare (1,769,274-acre) protected area that is the Cerrado’s second largest.

The lizard, of the Bachia genus, resembles a snake due to its lack of legs and pointed snout, which help it move across the predominantly sandy soil formed by the natural erosion of the escarpments of the Serra Geral. Other suspected new species include a dwarf woodpecker (genus Picumnus) and horned toad (genus Proceratophrys).

“It’s very exciting to find new species and data on the richness, abundance, and distribution of wildlife in one of the most extensive, complex, and unknown regions of the Cerrado,” said CI biologist Cristiano Nogueira, the expedition leader. “Protected areas such as the Ecological Station are home to some of the last remaining healthy ecosystems in a region increasingly threatened by urban growth and mechanized agriculture.”

The team also recorded several threatened species such as the hyacinth macaw, marsh deer, three-banded armadillo (tatu-bola), the Brazilian merganser, and the dwarf tinamou among more than 440 species of vertebrates documented during the 29-day field expedition. – sd

>Police: Pa. man killed over nickname mix-up

>

Police say a York man was killed because he had a similar nickname as the attackers’ intended target.

York police say 29-year-old Omar Maru Dowling, also known as “Big O,” was killed April 11. At least 18 shots were fired in the attack.

Two 29-year-old York men were charged Tuesday with conspiracy and criminal homicide. Police Lt. Ron Camacho says Wilfredo Rodriguez and Dennis Mercado were trying to get revenge for a botched August drug deal in which Rodriguez was shot. But Camacho says the man they were looking for wasn’t Dowling, but someone with a similar nickname.

Rodriguez and Mercado are held without bail; it was not immediately clear if they had lawyers. – cd

>New shrew discovered in Ireland

>

Ireland, which has seen an immigration surge in recent years, has a new foreigner on its shores, scientists said Monday: the greater white-toothed shrew.

The mammal, Crocidura Russula, has been discovered in parts of the midlands and south-west of the republic. Its natural range is in parts of Africa, France and Germany.

Professor Ian Montgomery, head of the School of Biological Sciences at Queen’s University in Belfast, says the animal is likely to have been introduced recently to Ireland and the discovery of a new mammal species in Ireland is extremely rare.

“Most species which occur in Ireland also occur in Britain but the nearest this species of shrew has been found is on the Channel Islands and the Scilly Isles.”

He said the discovery was probably the result of an accidental introduction from “continental Europe to Ireland and has resulted in a rapid increase in numbers over a short period”.

The shrew, which has been spotted in Counties Tipperary and Limerick, is only the third new mammal to be found on the island in almost 60 years.

The presence of the new immigrant came to light when Dave Tosh, from Queen’s University, was studying the diet of the Barn Owl while working with University College Cork and BirdWatch Ireland.

Analysing owl pellets (regurgitated food remains) sent to him by John Lusby, Birdwatch’s barn owl research officer, Tosh began to find large shrew skulls, too big to be the skulls of Ireland’s native pygmy shrew.

Last month, the presence of the greater white-toothed shrews was confirmed when seven were trapped at four locations in Tipperary.

The discovery now raises issues of ecological impact and control.

The scientists say that while the new shrew is likely to sustain threatened birds of prey including the barn owl, it could lead to the loss of small native mammals including the pygmy shrew. – ap

>Marching sand dunes stir up Mars mystery

>

Sand grains stirred up by the winds of Mars are tossed higher and farther than those kicked up by winds on Earth, a new study finds. The results could help explain how dunes migrate across the Martian surface as well as what whips up dust storms that blow across the red planet.

Scientists first noticed dunes on the Martian surface in pictures taken by NASA’s Mariner missions in the 1970s and have seen dust storms of all sizes spread across the planet — one major storm in 2005 was even visible through a simple backyard telescope. But these features have puzzled astronomers because Mars has almost no atmosphere and very weak winds that seem unlikely to be able to sculpt dunes or whip up storms.

To help solve this conundrum, a team of scientists recently conducted wind tunnel simulations of windblown sand grains under the conditions found on both Earth and Mars to figure out how the particles would behave on these planets with vastly different atmospheres. Their results are detailed in the April 28 issue of the journal Proceedings of the National Academy of Sciences. – msnbc

>Israeli military enlists robotic soldier

>

Israel’s newest soldier can see at night, never nods off on sentry duty and can carry 660 pounds without complaining.

The Guardium, an unmanned ground vehicle commissioned by the Israeli military and shown to The Associated Press on Monday, is essentially a robotic soldier, among the first in the world to be operational. It can replace human soldiers in dangerous roles, cutting casualty rates.

Like the pilotless drones that have become a mainstay of air forces in Israel, the U.S. and elsewhere, the four-wheeled Guardium is operated from a command room that can be far from the front line. It can be mounted with cameras, night-vision equipment and sensors, as well as more lethal tools like machine guns. – msnbc

>Robot creepily re-assembles itself, plans downfall of humanity

Oh, great. Just when you thought that at least we could try averting the imminent robot takeover by smashing them to pieces, some bunch of so-called ‘scientists’ comes along and invent a robot that re-assembles itself after you kick it to bits. Thanks guys. Don’t provoke it, you’ll only make it angry. It can’t be bargained with. It can’t be reasoned with. It doesn’t feel pity, or remorse, or fear. And it absolutely will not stop, ever, until you are dead. – met

>LSD inventor Albert Hofmann dies

>

Albert Hofmann, the Swiss chemist who discovered the hallucinogenic drug LSD, has died of a heart attack at his home in Basel at the age of 102.

Mr Hofmann first produced LSD in 1938 while researching the medicinal uses of a crop fungus.

He accidentally ingested some of the drug and said later: “Everything I saw was distorted as in a warped mirror.”

He argued for decades that LSD could help treat mental illness, but in the 1960s it became a popular street drug.

‘Turn on, tune in, drop out’

While working with the drug in the Sandoz pharmaceutical laboratory a few years after first producing it, Mr Hofmann ingested some of the drug through his fingertips.

He went home and experienced what he described as visions of “fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colours”.

The drug was popularised by Harvard professor Timothy Leary who suggested that people “turn on, tune in, drop out”.

Rock stars and the counter-culture of the 1960s picked up LSD as a wonder drug but horror stories began to emerge of users suffering permanent psychological damage.

LSD was made illegal in many countries beginning in the late 1960s. – bbc
