Renting better then bying

Renting Makes More Financial Sense Than Homeownership
By Jack Hough

I have something un-American to confess: I rent an apartment, despite having enough money to buy a house. I plan to keep renting for as long as I can. I'm not just holding out for better prices. Renting will make me richer.

I normally write about stocks for SmartMoney.com, but the boss asked me to explain to readers my reason for renting. Here goes: Businesses are great investments while houses are poor ones, so I'd rather rent the latter and own the former.

Stocks vs. Houses: Returns

Shares of businesses return 7% a year over long time periods. I'm subtracting for inflation, gradual price increases for everything from a can of beer to an ear exam. (After-inflation or "real" returns are the only ones that matter. The point of increasing wealth is to increase buying power, not numbers on an account statement.) Shares have been remarkably consistent over the past two centuries in their 7% real returns. In Jeremy Siegel's book, "Stocks for the Long Term," he finds that real returns averaged 7.0% over nearly seven decades ending 1870, then 6.6% through 1925 and then 6.9% through 2004.

Can Bill Gates Help Africa Feed Itself?

By Vivienne Walt / Paris

The global economy might be reeling from the shakeout on Wall Street, but two of the world's richest businessmen are vowing to spend tens of millions of dollars more — not on bolstering their own companies, but in helping the world's poorest.

With Congress locked in talks over a mammoth bailout package, Bill Gates and Howard Buffett (Warren's oldest son) announced at the United Nations on Wednesday that their private foundations will plow more than $75 million into helping small farmers in Africa and Latin America to sell their crops as food aid — a move which could potentially overhaul the decades-old — and often criticized — global food aid system.

North America's smallest dinosaur


Researcher finds tiny dino in world of giants

By Jeffrey Jones

CALGARY, Alberta (Reuters) - A Canadian researcher has discovered what is believed to be North America's smallest dinosaur, a 70-million-year-old chicken-sized beast that was also unusual for its diet of insects.


Called the Albertonykus borealis, the odd-looking creature had bird-like features including slender legs, jaws like pincers and stubby arms with big claws.


Its bones were excavated near Red Deer, in fossil-rich Alberta, in 2002 among about 20 Albertosaurus remains, and went unnoticed.

Robotic helicopters are pictured prior to an airshow on the Stanford University campus in Palo Alto, California, September 15, 2008.


The airshow, which involves helicopters that have taught themselves to fly by watching other helicopters, is a demonstration of an "apprenticeship learning algorithm" developed by computer science professor Andrew Ng and other students at the Stanford Artificial Intelligence Lab, where robots learn by observing an expert, rather than by having software engineers attempt to write instructions from scratch.

Israel cashing in on caviar crisis, but is it kosher?
by Charly Wegman

KIBBUTZ DAN, Israel (AFP) - Thousands of kilometres (miles) from the Caspian Sea, Israel is cashing in on a global caviar crisis, gearing up to export tonnes of the delicate and costly roe from farm-raised sturgeon.

It may not be quite kosher -- depending on who you ask -- but there is definitely a huge international demand for the gourmet treat.

"This is top quality," says Yigal Ben Tzvi, managing director of Caviar Galilee, holding up a blue tin of "Made in Israel" sturgeon eggs, which he says caviar giant Petrossian buys wholesale at 2,800 dollars (2,000 euros) a kilo.

De Dion Buton


1906 Model

The company started soon to produce engines and to provide to other car manufacturers, such as Latil, Peugeot or Renault. The engines of Dion were used by more than 150 other companies.

In 1900, Of Dion-Button was the largest manufacturer of cars in the world. The company produced 400 cars and 3.200 engines this year there. The company was the first to manufacture an engine V8 in series, in 1910. These figures of production will be exceeded by those of Panhard & Levassor before the First World War, then by other manufacturers like Peugeot or Renault, but especially Citroen and its production “in series”.

Artificial life

Biologists on the Verge of Creating New Form of Life
By Alexis Madrigal

A team of biologists and chemists is closing in on bringing non-living matter to life.

It's not as Frankensteinian as it sounds. Instead, a lab led by Jack Szostak, a molecular biologist at Harvard Medical School, is building simple cell models that can almost be called life.

Szostak's protocells are built from fatty molecules that can trap bits of nucleic acids that contain the source code for replication. Combined with a process that harnesses external energy from the sun or chemical reactions, they could form a self-replicating, evolving system that satisfies the conditions of life, but isn't anything like life on earth now, but might represent life as it began or could exist elsewhere in the universe.

Thai leader forced to resign over TV cooking show
By AMBIKA AHUJA, Associated Press Writer
BANGKOK, Thailand - Thailand's prime minister was forced out of office Tuesday along with his Cabinet after a court ruled that he had broken a conflict-of-interest law by hosting TV cooking shows.

Samak Sundaravej's party later unanimously agreed to re-nominate him as a candidate for prime minister, indicating that Thailand is still not free from its deep political crisis that has virtually paralyzed the government, spooked the financial markets and scared away tourists.

Poor building of schools in China

BEIJING — A Chinese government committee said Thursday that a rush to build schools during the country’s recent economic boom might have led to shoddy construction that resulted in the deaths of thousands of students during a devastating earthquake in May.
