Mystery Of The Missing Mini-Galaxies

Something missing? (Image: NASA/ESA/STScI/AURA/A. Aloisi)

From New Scientist:

LIKE moths about a flame, thousands of tiny satellite galaxies flutter about our Milky Way. For astronomers this is a dream scenario, fitting perfectly with the established models of how our galaxy's cosmic neighbourhood should be. Unfortunately, it's a dream in more ways than one and the reality could hardly be more different.

As far as we can tell, barely 25 straggly satellites loiter forlornly around the outskirts of the Milky Way. "We see only about 1 per cent of the predicted number of satellite galaxies," says Pavel Kroupa of the University of Bonn in Germany. "It is the cleanest case in which we can see there is something badly wrong with our standard picture of the origin of galaxies."

We DO like Mondays... But We Really Don't Like The Mid-Week Misery Of Wednesday

From The Daily Mail:

With work beckoning after a relaxing weekend, Monday has traditionally been thought of as the most miserable day of the week.
But with memories of the days off still fresh, Mondays are actually the second happiest day of the week according to researchers.

Peter Dodds and Christopher Danforth, applied mathematicians at the University of Vermont, believe they have found a way to measure collective happiness and found we are at our lowest on Wednesdays.

From Space Flight Now:

Managers in charge of an October flight test of NASA's new Ares rocket defended the merits of the $350 million launch Sunday, telling reporters the demo provides valuable experience for engineers, no matter what booster the agency uses to replace the retiring space shuttle.

"We have a very high confidence level that Ares 1-X is germane to NASA, period," said Bob Ess, the flight's mission manager. "No caveats."

The Ares 1-X vehicle, a 327-foot-tall rocket that nearly reaches the rafters of the mammoth Vehicle Assembly Building, is undergoing final checks before its scheduled Oct. 31 launch.

The Origin of Rubber Boots

ROASTING RUBBER: Amazonian Indians may have originated the rubber boot over a campfire. ISTOCKPHOTO/SKI88

From Scientific American:

Galoshes seem to have come from a little fire, Amazonian Indians' boredom and Charles Goodyear's luck.

Perhaps the Indians roasted them like s'mores—rotating them ever so slowly to make sure every side got just dark enough, but not so long that they caught on fire. Or maybe they went all out, expediting the process and blowing out any flames. Of course, for the art of hovering a rubber-coated foot over a fire, one's pain tolerance may have ultimately determined how long the process went on.

Can Microsoft's Bing, or Anyone, Challenge Google?

From Time Magazine:

Every year, the market-research firm Millward Brown conducts a survey to determine the economic worth of the world's brands — in other words, to put a dollar value on the many corporate logos that dominate our lives. Lately the firm's results have been stuck on repeat: Google has claimed the top spot for the past three years. The most recent report values Google's brand — those six happy letters that herald so many of our jaunts down the Web's rabbit hole — at more than $100 billion.

Tweeting No Longer For The Birds, But Not Just For Twitter, Either

From The Globe And Mail:

Tweeting used to be for the birds, but the term has taken on a whole new meaning with the explosion in popularity of Twitter, an online service that allows users to blog via 140-character “tweets.”

But efforts by Twitter to trademark the word “tweet” have suffered a major setback after U.S. officials said others might have beaten the microblogging pioneer to the punch.

How We Support Our False Beliefs

From Science Daily:

ScienceDaily (Aug. 23, 2009) — In a study published in the most recent issue of the journal Sociological Inquiry, sociologists from four major research institutions focus on one of the most curious aspects of the 2004 presidential election: the strength and resilience of the belief among many Americans that Saddam Hussein was linked to the terrorist attacks of 9/11.

Although this belief influenced the 2004 election, they claim it did not result from pro-Bush propaganda, but from an urgent need by many Americans to seek justification for a war already in progress.

Powerful Ideas: Beer Waste Makes Fuel

From Live Science:

After beer is made, the waste from breweries could help generate power, researchers now suggest.

One problem brewers face is what to do with the thousands of tons of grain left over at the end of the brewing process. In the past, they just sold the waste to farmers who either fed it to their animals or spread it on their fields as fertilizer. However, in Europe, given reductions in cattle breeding and stricter regulations on what waste is allowed on land, neither option is as easy anymore.

Will Antitrust Probe Keep Microsoft, Yahoo Apart?

From The Miami Herald/AP:

WASHINGTON -- Yahoo Inc. and Microsoft Corp. hope that by joining forces, they can tilt the balance of power in Internet search away from Google Inc. First, however, Yahoo and Microsoft have to convince regulators that their plan won't hurt online advertisers and consumers.

As the U.S. Justice Department reviews the proposed partnership, approval figures to hinge on this question: Will the online ad market be healthier if Google's dominance is challenged by a single, more muscular rival instead of two scrawnier foes?

Cutting The Cord: America Loses Its Landlines

From The Economist:

Ever greater numbers of Americans are disconnecting their home telephones, with momentous consequences.

MUCH has been made of the precipitous decline of America’s newspapers. According to one much-cited calculation, the country’s last printed newspaper will land on a doorstep sometime in the first quarter of 2043. That is a positively healthy outlook, however, compared with another staple of American life: the home telephone. Telecoms operators are seeing customers abandon landlines at a rate of 700,000 per month. Some analysts now estimate that 25% of households in America rely entirely on mobile phones (or cellphones, as Americans call them)—a share that could double within the next three years. If the decline of the landline continues at its current rate, the last cord will be cut sometime in 2025.

WASHINGTON — Highly invasive mussels are lurking on the Northwest's doorstep, threatening to gum up the dams that produce the region's cheap electricity, clog drinking water and irrigation systems, jeopardize aquatic ecosystems and upset efforts to revive such endangered species as salmon.

Despite efforts to stop them, the arrival of zebra and quagga mussels may be inevitable.

Moonquake Mystery Deepens

From Earth Magazine:

Between 1969 and 1972, five Apollo missions installed seismic stations at their landing sites on the nearside of the moon. Because the moon was thought to be seismically dead, the instruments were left almost as an afterthought to detect meteor strikes. But from the time the stations were switched on until they were decommissioned in 1977, they recorded hundreds of internally generated moonquakes, some as strong as magnitude 5.5 on the Richter scale.

New Way To Reproduce A Black Hole?

From Science Daily:

ScienceDaily (Aug. 22, 2009) — Despite their popularity in the science fiction genre, there is much to be learned about black holes, the mysterious regions in space once thought to be absent of light. In a paper published in the August 20 issue of Physical Review Letters, Dartmouth researchers propose a new way of creating a reproduction black hole in the laboratory on a much-tinier scale than their celestial counterparts.

The new method to create a tiny quantum sized black hole would allow researchers to better understand what physicist Stephen Hawking proposed more than 35 years ago: black holes are not totally void of activity; they emit photons, which is now known as Hawking radiation.

These bolts of upwards lightning, one type among a variety of electrical discharges now known to occur above thunderstaorms, are called gigantic jets, and were only first discovered in 2001.

From The Daily Mail:

Traditional lightbulbs will disappear from our shops in just ten days.

All conventional pearl, incandescent lightbulbs are being banned by the European Union to slash energy bills and carbon dioxide emissions.

The move covers every type of frosted traditional bulb, from the 60 watt pearl bulbs used in table lamps to more specialised opaque 25 and 40 watt bulbs shaped like golf balls and candles.

Clear and frosted 100 watt lightbulbs will also not be on sale from September 1.
