BlackBerry CEO says Samsung?s smartphone security will never be ?top-notch? [updated]

Late night television has once again become a battleground: NBC's mad at Jay Leno for bashing the network and there's renewed talk about a Jimmy Fallon takeover at The Tonight Show. Leno, of course, is not going quietly. But this week we learned that the new late night war will be waged in a surprisingly formulaic way, with bad jokes and big cities and plenty of power players, on these fronts:

LONDON (AP) ? Two victories in four days over rival Barcelona propelled Real Madrid to first place in the AP global soccer rankings.

Cristiano Ronaldo's role in Madrid's victories was not enough to make him player of the week in The Associated Press survey of 22 global soccer journalists. Ronaldo was beaten by Gareth Bale of Tottenham, who has been scoring spectacular match-winning goals.

Shinji Kagawa became the first Japanese player to enter the top three in the player rankings following his hat trick for Manchester United.

Bale scored 170 points out of a possible 220 from the AP panel, which awards 10 points to the best player or team, going down to one point for the 10th best.

Ronaldo was only three points behind after impressive performances in the Copa del Rey and Spanish league, and Kagawa won 159 points for three neatly taken goals that won him widespread praise in England and Japan.

Leonardo Bertozzi of ESPN Brazil paid tribute to Bale, but said Ronaldo has now scored in six consecutive games against Barcelona. He came off the bench in the second half of the Copa del Rey game, "and was still able to have more shots than the entire Barcelona team throughout the match."

Kagawa's exploits in United's 4-0 thrashing of Norwich clearly delighted Japanese supporters.

"Provided he stays fit, building the necessary strength and stamina, Kagawa will have plenty of goal-scoring opportunities like Saturday with Rooney and Van Persie commanding so much of the attention of the opposing defense," said panelist Shintaro Kano of Japan's Kyodo news agency.

"His touch amid congestion inside the box is first class, and United fans have only seen a glimpse of what Dortmund supporters saw in Kagawa. At this rate, the 12 million pounds Alex Ferguson paid for him will seem like a bargain as he will be under contract at United for the peak years of his career," said Kano.

South Korea-based John Duerden pointed out that the hat trick was the first in the English Premier League by an Asian player.

"A classy hat trick for a classy player," Duerden said.

James Porteous of The South China Morning Post in Hong Kong said Bale's three goals in two games made him a natural for top spot.

Porteous said, "he is quite simply single-handedly dragging Spurs towards Europe, and is sure to be in demand by Europe's biggest clubs when the transfer window reopens."

Manchester United, 12 points clear at the top of the Premier League, was a distant second with 157 points to Real Madrid's 202. Bayern Munich, a massive 17 points clear in the Bundesliga, is third with 148 after a narrow weekend victory over Hoffenheim.

Aurelio Capaldi, of Italy's RAI Sport, said Madrid's position at the top of the AP rankings had been tough to achieve.

"Real Madrid were capable of beating Barcelona twice in five days and they were particularly impressive at the Camp Nou, where they demolished their eternal rivals and gained the right to be in the final of the Copa del Rey," said Capaldi. "Real look in very good form and Jose Mourinho was right in trusting the 19-year-old French defender Raphael Varane, who played with intelligence, accuracy and self-belief."

Tottenham, currently third in the league, was voted fourth for its Bale-inspired 2-1 victory over Arsenal, just three points behind Bayern, while a 3-0 win over Lazio nudged AC Milan two spots ahead of Serie A leader Juventus in fifth place with 103 points. The last five teams ? Liverpool, Juventus, Borussia Dortmund, Schalke and Inter Milan ? all got less than 60 votes each.

A hat trick was only enough for fourth place for Liverpool's Uruguay striker, Luis Suarez, meaning three of the top four players perform in the Premier League. He was awarded 136 points, 60 ahead of fifth-place Robert Lewandowski, the Poland forward who scored twice in Borussia Dortmund's 3-1 victory over Hannover.

Italy's Giampaolo Pazzini made his first appearance in the top 10 in sixth place after scoring twice for Milan against Lazio. Francesco Totti, Roma's 36-year-old captain, continues to prove his brilliance with a penalty that made it 225 goals for a single club, equaling Swedish great Gunnar Nordahl from the 1950s for second place on Serie A's all-time scoring list.

'True grit' erodes assumptions about evolution of Earth's first grasslands

Mar. 4, 2013 ? Dining on field grasses would be ruinous to human teeth, but mammals such as horses, rhinos and gazelles evolved long, strong teeth that are up to the task.

New research led by the University of Washington challenges the 140-year-old assumption that finding fossilized remains of prehistoric animals with such teeth meant the animals were living in grasslands and savannas. Instead it appears certain South American mammals evolved the teeth in response to the gritty dust and volcanic ash they encountered while feeding in an ancient tropical forest.

The new work was conducted in Argentina where scientists had thought Earth's first grasslands emerged 38 million years ago, an assumption based on fossils of these specialized teeth. But the grasslands didn't exist. Instead there were tropical forests rich with palms, bamboos and gingers, according to Caroline Str?mberg, UW assistant professor of biology and lead author of an article in Nature Communications.

"The assumption about grasslands and the evolution of these teeth was based on animal fossils," Str?mberg said. "No one had looked in detail at evidence from the plant record before. Our findings show that you shouldn't assume adaptations always came about in the same way, that the trigger is the same environment every time."

To handle a lifetime of rough abrasion, the specialized teeth -- called high-crowned cheek teeth -- are especially long and mostly up in the animals' gums when they are young. As chewing surfaces of the teeth wear away, more of the tooth emerges from the gums until the crowns are used up. In each tooth, bone-like dentin and tough enamel are complexly folded and layered to create strong ridged surfaces for chewing. Human teeth have short crowns and enamel only on the outside of each tooth.

In Argentina, mammals apparently developed specialized teeth 20 million years or more before grasslands appeared, Str?mberg said. This was different from her previous work in North America and western Eurasia where she found the emergence of grasslands coincided with the early ancestors of horses and other animals evolving specialized teeth. The cause and effect, however, took 4 million years, considerably more lag time than previously thought.

The idea that specialized teeth could have evolved in response to eating dust and grit on plants and the ground is not new. In the case of Argentine mammals, Str?mberg and her co-authors hypothesize that the teeth adapted to handle volcanic ash because so much is present at the study site. For example, some layers of volcanic ash are as thick as 20 feet (six meters). In other layers, soils and roots were just starting to develop when they were smothered with more ash.

Chewing grasses is abrasive because grasses take up more silica from soils than most other plants. Silica forms minute particles inside many plants called phytoliths that, among other things, help some plants stand upright and form part of the protective coating on seeds.

Phytoliths vary in appearance under a microscope depending on the kind of plant. When plants die and decay, the phytoliths remain as part of the soil layer. In work funded by the National Science Foundation, Str?mberg and her colleagues collected samples from Argentina's Gran Barranca, literally "Great Cliff," that offers access to layers of soil, ash and sand going back millions of years.

The phytoliths they found in 38-million-year-old layers -- when ancient mammals in that part of the world developed specialized teeth -- were overwhelmingly from tropical forests, Str?mberg said.

"In modern grasslands and savannas you'd expect at least 35 to 40 percent -- more likely well over 50 percent -- of grass phytoliths. The fact we have so little evidence of grasses is very diagnostic of a forested habitat," she said.

The emergence of grasslands and the evolution of specialized teeth in mammals are regarded as a classic example of co-evolution, one that has occurred in various places around the world. However, as the new work shows, "caution is required when using this functional trait for habitat reconstruction," the co-authors write.
