After months of rumours and speculation, Samsung finally launched its new flagship smartphone, the Galaxy S3 on 3 May. The device flaunts a 4.8in Super AMOLED display with PenTile sub-pixels. The new display is expected to be much crisper and sharper when compared to other screens owing to higher pixel density. Users could be upset to see the display which is already integrated in the Galaxy Nexus. Tech enthusiasts could be expecting something which could deal a killer blow. Samsung's choice to use PenTile layout in its devices could be to ensure durability and longevity.

Samsung Galaxy S3 Features Super AMOLED display with PenTile sub-pixels

Samsung's Philip Berne has explained the reason behind the usage of PenTile layout to Mobile Burn. It is reported that the blue sub-pixels on AMOLED displays will deteriorate faster when compared to red and green sub-pixels. In a PenTile layout, the arrangement of sub-pixels include RGBG (red, green, blue, green) format. Certainly, there are more green sub-pixels and very few red or blue sub-pixels in it than RGB layout. Hence, the AMOLED displays that include PenTile layout will reportedly offer longevity than the RGB layout.

Berne added that Samsung users usually kept their gadgets for 18 months or longer, and so they have to provide peak performance. So, the smartphone uses a PenTile AMOLED display as it lasts longer.

Some users complain that PenTile displays do not offer a crisp look as an RGB display. Perhaps, there is odd colour fringing along the edges of images. "While Berne did agree that the PenTile arrangement's faults are pronounced at lower resolutions, such as qHD or WVGA, high-resolution displays hide the problems due to sheer density of pixels," elaborates Mobile Burn.

Bern emphasised that the Galaxy S3 has been improved over the Galaxy Nexus's 4.65in 720p Super AMOLED screen as it incorporates smaller gaps in its sub-pixel matrix resulting in reduced fringing effects of the PenTile layout.

The argument over the PenTile and RGB layouts may reduce as the technology reaches the peak with the debut of higher density displays in the upcoming smartphones.

DARLINGTON, SC (WMBF) - City officials say Darlington is definitely getting a big boost in business from the Southern 500, with people staying in local hotels, eating at the restaurants there and shopping locally.

Local business owners and vendors at the Darlington Racewaygive mixed reactions on how business is really going this week.

"There's been a lot more traffic coming along and well it seems like there's going to be a lot more coming," said Riley Carter who works at one of the shops at Ivana's near the Darlington Raceway.

Tens of thousands of NASCAR fans are expected to flock to Darlington to attend the Southern 500.

Local businesses like the RacewayGrill have had an increase in customers this week.

Some NASCAR fanssay the Southern 500 has turned into more than just a one-day race.

"We come out for a week for two, when before we used to just come for a couple days," said NASCAR fan, Roy Ivey Jr.

Several events featuring the racecar drivers were held across the Pee Dee days before the race, bringing in more fans for a longer period of time.

"The city gets more revenue and more business, more people that's coming in and enjoying the little town of Darlington," said Carter.

Darlington Raceway directors released data from a study, showing state-wide, the raceway brings in about $54 million a year.

Located in a quiet neighbourhood in Petaling Jaya, is an extraordinary bungalow that encompasses the simplicity of modern architecture and the use of an anti-oxidant solution to ensure, literally, healthy living.

This is probably the first house in Malaysia to use such an anti-oxidant solution in the building structure and finishing material.

Property owner Melvyn Kanny, 44, is an astute architect with a prudent character who not only designed and constructed his dream home with a green theme but practically, imbued it with life-enhancing properties.

From the outside, the house stands out uniquely from the suburban dwellings typical of Kampung Tunku. The construction materials used seem to be similar to the old houses around this part of PJ although rendered in a contemporary style.

The gate was constructed out of raw steel with a rusty patina. Other interesting parts of the house include the eye-catching louvres that enhance the faade. The walls too were built with in raw concrete blocks. Visitors could easily be mistaken that the house was still unfinished.

"Oh yes it is finished I assure you," said Melvyn, as if reading my mind.

"The rusted steel is actually oxidized, raw steel - we did it by applying salt to the steel and allowing it to weather, giving it an evenly rusted look. A sealant was applied to preserve it from deterioration."

Before I could ask why not save the trouble by just painting it, he explained that the green concept was based on the maxim of "less is more". Unlike other builders of green houses who adopt an active approach like having photo-voltaic cells, wind turbines, heat pumps, etc., Melvyn's approach to design was more passive.

"I wanted to create a home that was green yet incur minimal, additional costs. People often think of green homes as those that that are run on solar power and so on. However, that is only one part of what green homes are supposed to be."

SAN ANTONIO, May 7 (UPI) -- U.S. researchers say they have found a clue as to why the naked mole-rat lives many years longer than any other mouse or rat -- and it's all about proteins.

Scientists at the University of Texas Health Science Center report the naked mole-rat's cellular machines for protein disposal -- called proteasome assemblies -- differ in composition from those of other, shorter-lived rodents, giving the naked mole-rat a superior ability to remove damaged proteins and maintain protein integrity.

Researchers said the strange, hairless rodents maintain exceptional levels of that integrity throughout their long and healthy life.

"More effective removal of damaged proteins within the cell would enable the animal to be able to maintain good function and is likely to contribute to its excellent maintenance of good health well into its third decade of life," researcher Rochelle Buffenstein said.

The study, conducted at the university's Barshop Institute of Longevity and Aging Studies, has been published in the journal PLoS ONE.

An intriguing clue to longevity lurks in the sexual maturation timetable of female mammals, Jackson Laboratory researchers and their collaborators report.

Jackson researchers including Research Scientist Rong Yuan, Ph.D., had previously established that mouse strains with lower circulating levels of the hormone IGF1 at age six months live longer than other strains. In research published May 7 in the Proceedings of the National Academy of Sciences, Yuan and colleagues report that females from strains with lower IGF1 levels also reach sexual maturity at a significantly later age.

"This suggests a genetically regulated tradeoffdelayed reproduction but longer lifethat is at least partially mediated by IGF1," Yuan says.

The researchers conclude that IGF1 may co-regulate female sexual maturation and longevity. They showed that mouse strains derived from wild populations carry specific gene variants that delay sexual maturation, and they identified a candidate gene, Nrip1, involved in regulating sexual maturation that may also affect longevity by controlling IGF1 levels.

Yuan notes that researchers in England recently showed that higher levels of IGF1 and other hormones in girls are associated with earlier age of menarche (onset of menstruation). In the newly published research, Yuan and colleagues used the biological benchmark of vaginal patency (VP) as indicator of sexual maturity in mice.

Mice from the inbred strain C57BL/6J, also known as "Black 6," showed 9 percent lower IGF1, 6 percent delayed age of VP and 24 percent extended lifespan compared to a Black 6 substrain that carries a gene variation that increases IGF1.

Using a technique called haplotype mapping, the researchers screened genetic and physiological data for 31 different inbred mouse strains and found genes that regulate female sexual maturation and lifespan, on Chromosomes 4 and 16. They showed that wild-derived mouse strains share a genetic profile associated with delayed VP and increased longevity, and identified a candidate gene, Nrip1, that controls IGF1 and age of VP.
