Opera 10 To Emerge Tuesday

From CNET:

Opera Software will release version 10 of its browser Tuesday, a new version of software that has loyal fans but not as much adoption as several rivals.

The Norwegian company says Opera 10 has better performance, a Turbo mode for slow Internet connections, support for a variety of Web standards such as Web fonts, and improvements to the Opera Mail feature. The company issued two Opera 10 release candidates for the free software in the last week, and spokeswoman Falguni Bhuta announced Monday the final version will arrive September 1.

7 Equipment Breakthroughs That Shook Up Sports

From Popular Mechanics:

It's one of the most entertaining games of cat and mouse in the sports world. A competitor, or a manufacturer, comes up with a piece of gear that threatens to turn a sport upside down. Then the game's powers that be are faced with a dilemma. Ban it outright? Rewrite the rule book? Or just let it be? Just such a controversy is raging in swimming, where streamlined suits have been banned, but it's important to remember that seeking an edge through better equipment is as old as sport itself. Here are seven pieces of gear that shook up their respective sports and sent officials back to the drawing board.

From The New York Times:

For 33 years, Peter A. Rona has pursued an ancient, elusive animal, repeatedly plunging down more than two miles to the muddy seabed of the North Atlantic to search out, and if possible, pry loose his quarry.

Like Ahab, he has failed time and again. Despite access to the world’s best equipment for deep exploration, he has always come back empty-handed, the creature eluding his grip.

The animal is no white whale. And Dr. Rona is no unhinged Captain Ahab, but rather a distinguished oceanographer at Rutgers University. And he has now succeeded in making an intellectual splash with a new research report, written with a team of a dozen colleagues.

From Time Magazine:

After Hurricane Katrina flattened New Orleans exactly four years ago, on Aug. 29, 2005, the city emerged as an inadvertent symbol of global warming, the first American victim of climate change. Over 200,000 homes were destroyed during the Category 5 hurricane. But in the years since, the Crescent City has quietly embraced a new and unexpected role as a laboratory for green building. Sustainable development groups that range from the international nonprofit Global Green to earth-friendly celebrities like Brad Pitt descended on New Orleans, determined not just to build the city back, but to build it back green. "It's going to come back," says Matt Petersen, the president of Global Green USA. "But we want to build it better than it was before."

US Scientists Set To Reveal The True Colour Of Dinosaurs

From Independent:

A new technique that identifies the hue of ancient birds may help a Yale team with bigger beasts.

It is a question that has baffled the greatest scientific minds – and those of the average seven-year-old: what colour were dinosaurs?

Now a dramatic breakthrough in fossil examination has sparked a race to discover an answer that may satisfy the scientific community as well as anxious crayon-wielders. A research team at Yale University believes it has established a technique that can identify the colour of fossilised feathers and fur. Preliminary results suggest that the true colours of dinosaurs may soon be revealed.

From Technology Review:

Winemakers disappointed by organic methods have turned to biodynamics as the purest route to wine that's true to soil, grape, and climate.

For years the question in winemaking was how technology could make wine better. This was especially true if the wine was Californian. When California cabernet sauvignon bested the best of Bordeaux--in a legendary blind tasting, the "Judgment of Paris," convened by the English wine merchant Steven ­Spurrier--it was a moment of great national pride at the time of America's Bicentennial, and it was achieved in part because California winemakers had used technology in ways tradition-bound French winemakers would not. As California wine became respectable, Silicon Valley millionaires bought vineyards in Napa and Sonoma counties. California wine and tech soon enjoyed a happy marriage.

From Science Daily:

ScienceDaily (Aug. 31, 2009) — When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

In mice, nanobees delivered the bee toxin melittin to tumors while protecting other tissues from the toxin's destructive power. The mice's tumors stopped growing or shrank. The nanobees' effectiveness against cancer in the mice is reported in advance online publication Aug. 10 in the Journal of Clinical Investigation.

What Makes A Psychopath? Answers Remain Elusive

Psychopathic behavior can take many forms, not all of it violent. But some common themes underlie the condition, with pieces of a brain's emotional machinery missing. Psychopaths often lack empathy, guilt, conscience or the ability to show remorse. Image credit: stockxpert

From Live Science:

As exaggerated as many popular depictions of psychopaths often are, many nevertheless do pose a genuine danger to others. So what makes psychopaths the way they are?

Scientists are now working toward uncovering the roots of this disorder in the brain. Their research could lead to ways to intervene against the disorder and hopefully prevent it from manifesting.

From Popular Science:

A new website lets you figure out how you might die, by sorting death data by cause of death, sex, and age. For American males ages 20-29, the most common cause of death is accidents (40.2 percent of deaths), followed by homicide (17.5 percent), and suicide (11.7 percent). Urinary tract infections? 0.3 percent.

The Death Risk Rankings site was compiled by researchers at Carnegie Mellon University, and seems to have about a zillion ways to organize the data. It's quite cumbersome to use, so I'm going to save you the effort.

Laser Tests Could Silence The Dentist's Drill

From New Scientist:

THE dentist's dreaded drill could become a medical relic thanks to laser tests which spot weaknesses in dental enamel in time to repair the surface before more drastic intervention is needed.

Dentists currently check for cavities with X-rays and metal probes, but these cannot detect weaknesses in the enamel while there is still a chance to repair it. David Wang, a graduate student at the University of Sydney in Australia, instead studied whether the propagation of sound waves through the enamel could provide an early warning (Optics Express, vol 17, p 15592).

Wikipedia To Color Code Untrustworthy Text

From Wired Science:

Starting this fall, you’ll have a new reason to trust the information you find on Wikipedia: An optional feature called “WikiTrust” will color code every word of the encyclopedia based on the reliability of its author and the length of time it has persisted on the page.

More than 60 million people visit the free, open-access encyclopedia each month, searching for knowledge on 12 million pages in 260 languages. But despite its popularity, Wikipedia has long suffered criticism from those who say it’s not reliable. Because anyone with an internet connection can contribute, the site is subject to vandalism, bias and misinformation. And edits are anonymous, so there’s no easy way to separate credible information from fake content created by vandals.

From The Telegraph:

Energy saving light bulbs are not as bright as their traditional counterparts and claims about the amount of light they produce are "exaggerated", the European Union has admitted.

Soon they will be the only kind of light bulb allowed, but now officials in Brussels have admitted that energy-saving bulbs are not as bright as the old-fashioned kind they are replacing.

From tomorrow a Europe-wide ban on traditional incandescent bulbs will begin to be rolled out, with a ban on 100W bulbs and old-style frosted or pearled bulbs.

From Time Magazine:

If you happened on Friday morning to walk into the Temple of Earth in Beijing — the nearly 500-year-old monument where Chinese emperors once prayed for good harvests — you would have noticed a steady drip. The environmental group Greenpeace placed ice sculptures of 100 children — made of the glacial meltwater that feeds China's great rivers — inside the temple, to symbolize the risk that climate change and disappearing ice poses to the more than 1 billion people in Asia threatened by water shortages.

From Popular Science:

Quick, get out your iPhone. Unlock it and slide over to that game you've been playing when your boss isn't looking. Now mute it, put the phone to sleep, close your eyes, and try to do that again. Can you do it? Didn't think so.

There's not a simple way to use touchscreens when you can't see what you're doing, which means 10 million blind and low-vision Americans can't use this ubiquitous technology. But what if you could feel it? What if the "slide to unlock" key was an actual slide? Even better, what if you could have a Braille iPhone?

Aspirin Does More Harm Than Good In Healthy People: Research

Aspirin: The drug does more harm than good in healthy people,
British researchers have said Photo: GETTY

From The Telegraph:

Healthy people who take aspirin to prevent a heart attack are doing themselves more harm than good, researchers have said.

Millions of people - including a substantial number of the "worried well" - take a daily dose of the drug in the belief it will keep them healthy.

But at a conference for leading doctors, British scientists said they have found that for healthy people taking aspirin does not significantly reduce the risk of a heart attack.

White Europeans 'Only Evolved 5,500 Years Ago After Food Habits Changed'

Photo: People with pale skin like model Lily Cole may be descended from Europeans who dramatically changed their diets

From The Daily Mail:

People in England may have only developed pale skin within the last 5,500 years, according to new research.

Scientists believe that a sudden change in the diet around that time from hunter-gathering to farming may have led to a dramatic change in skin tone to make up for a lack of vitamin D.

Farmed food is lacking in vitamin D and while humans can produce it when exposed to the ultraviolet light in sunlight darker skin is far less efficient at it.

Social Media As A Paradigm Shift

Photosynthetic Viruses Keep World's Oxygen Levels Up

From New Scientist:

NEXT time you take in a lungful of oxygen, consider this: it was made possible in part by ocean viruses.

The viruses, which infect single-celled algae called cyanobacteria, are hyperefficient photosynthesisers thanks to a unique set of genes.

Previous work had shown that cyanophage viruses have some photosynthesis genes, apparently used to keep the host cyanobacteria on life support during the infection, which otherwise knocks out the cells' basic functions.
