Long-term plasma TV tests show color, black-level changes but no major issues yet

Update January 19, 2012: See the latest test results here.

After a year in the lifespans of five 2011 plasma TVs that I've subjected to new long-term tests, all have shown some fluctuation in black level, light output, and color, and in some cases those changes are significant.

A few changes have been for the better, others can be fixed in calibration, and overall none is a "deal breaker" that radically changes my initial opinions of these TVs--all of which scored an 8 (Excellent) or 9 (Outstanding) in the Performance section of the reviews.

Before you read on, know that I aged these TVs in a controlled albeit accelerated process, leaving them on for basically six days a week for up to four months, so far. The charts below encompass a bit more than a year of normal use, assuming the average daily "on" time rate of 5.2 hours. When reading the charts, keep in mind that not all of the TVs have been aged for the same amount of time. See below for more details.… Read more

Researchers sequence cancer-resistant rodent's DNA

You wouldn't know it by looking at it, but the naked mole-rat has a few things to teach the animal world. It has fascinated researchers since it was discovered a few years ago that the rodents can live for 30 years, compared to the mouse's average life span of four.

So after launching an online database that details the lives and histories of more than 4,000 animal species, a consortium of researchers from around the world set out to sequence the genome of the naked mole-rate--which is native to the deserts of East Africa.

New saliva test reveals a person's approximate age

A new saliva test developed by geneticists at the University of California, Los Angeles, reveals a person's age within five years, a finding that could have many applications in medicine, at crime scenes, and more.

"With just a saliva sample, we can accurately predict a person's age without knowing anything else about them," says principal investigator Dr. Eric Vilain, a professor of human genetics, pediatrics and urology, in a UCLA news release.

The team's research, published online this week in the Public Library of Science's PLoS One journal, focuses on methylation, a process by … Read more

Dragon Age II: A change in the fight direction

Two years after the first Dragon Age: Origins game, developer BioWare is back with a new story to tell. Assuming the role of a character named Hawke (the sex and class of which you can customize), players will battle enemies, take on quests, and make various decisions in-game that ultimately alter the narrative. Gamers can even import their original Dragon Age choices if they choose to do so.

Does Dragon Age II trump its predecessor? Or is it filled with unwanted changes?

Jeff: Got a month to kill? That's the kind of time one can spend with BioWare's latest epic, Dragon Age II. Interestingly enough, the sequel plays more like a Mass Effect game than it does its predecessor. While hard-core RPG fans may view this as somewhat of a disservice, it certainly makes Dragon Age II a more accessible title at the end of the day.

For those who enjoyed the original Dragon Age: Origins on a console, the good news is that Dragon Age II plays even better on an Xbox 360 or PS3 this time around as the combat has been tweaked to resemble more of an action-RPG experience. This update is immediately noticeable--something we're not sure how we lived without during our Origins playthrough two years ago.

Choice is a main star of Dragon Age II, giving players a healthy amount of power with the decisions they make. While we really enjoyed this aspect of the game, it's definitely worth mentioning that we didn't always find the story as engaging as we would have hoped. At times it's confusing, others it's just uninteresting. Regardless, we still admire the fact that it's structured backward, in a way where players are told the ending just as things in the game are beginning to unfold.… Read more

Dragon Age II high-res PC texture pack compared

Electronic Arts' anticipated role-playing sequel Dragon Age II launched today for the PC, the Xbox 360, and the PlayStation 3. Reviews have been positive so far, but PC gamers had concerns that developer Bioware might be straying too far into console territory with the new game that features faster-paced combat and a more gamepad-friendly interface than the original, Dragon Age: Origins.

Perhaps to help convince PC gamers that it hasn't forgotten them, Bioware issued a free high-resolution texture pack download for Dragon Age II to coincide with today's launch. Designed for the PC version exclusively, the texture pack … Read more

preGame 42: Dragon Age II

Today on preGame we demo just a fraction of what there is to experience in the epic sequel from BioWare, Dragon Age II! Tune in to see how the improved combat system plays, and check out the advanced automation features that are available.

But first, we'll talk about last week's Nintendo 3DS sell-out debut in Japan and whether we think the 3D portable system will have similar success here in the States. Also, we'll try and make sense of the European PS3 seizing that has begun because of a patent infringement claim filed by LG.

The Carbon Age: Dark element, brighter future

Editors' note: This is a guest column. See Aaron Feaver's bio below.

Humankind has seen the Stone Age, the Golden Age, and the Iron Age. Some would argue the 20th century should be called the Silicon Age. Based on the events of its first 10 years, the 21st century may very well become known as the Carbon Age.

An important tension is unfolding between two types of carbon--atmospheric carbon in the form of carbon dioxide emissions, and elemental carbon as a building block for a new generation of devices designed to manage and abate those same pollutants. Our way of life has become dependent on energy generated by the process of extracting carbon from the earth in the form of fossil fuels and then burning it to form carbon dioxide. Meanwhile, we have begun developing carbon in solid form as an advanced material to counter the effects of its atmospheric cousin.

From the days of Thomas Edison, when an exhaustive list of carbon fibers were pyrolyzed, or thermochemically decomposed sans oxygen, from natural materials to form the filaments of the first successful lightbulb, to the development of activated carbon as the first commercial nanomaterial, to the discovery of buckyballs and the invention of carbon nanotubes, carbon has always generated an abundance of near-term change, cutting-edge breakthroughs, and even economic prosperity.

Our future will be brighter because new materials built on the many allotropes of carbon will function as the base-building blocks for a host of solutions--including cleaner batteries, cleaner water, and cleaner air--that will benefit our society, our economies, and our planet.

There are legions of carbon-based innovations to watch between now and 2020. As the research deepens and expands, and the technologies are fully developed and rolled out, new products and processes will be embraced by the automotive industry for hybrid electric vehicles, by electronics manufacturers for enhancing the life and usability of consumer goods, and by a variety of industrial customers to deliver an ever-increasing breadth of new ways to improve energy efficiency.

Here are the highlights of what we can expect:

Lithium ion batteries They are among the best-performing batteries because of their combination of relatively high power and energy density. They also, unfortunately, have a very high cost. While relatively well known in the market, the role of their carbon ingredients is less understood and appreciated. These batteries use a lithium-based oxide cathode, which can store an abundance of lithium but is not conductive. … Read more

Microsoft makes a return to Flight

One of the casualties of last year's layoffs at Microsoft was the Aces game studio responsible for the company's long-running Flight Simulator game.

At the time, Microsoft promised that the flight simulation franchise would continue in one form or another. This week, Redmond confirmed that it is indeed following through with a new title: Microsoft Flight.

The game is in its early development stages, with an alpha version nearly ready for internal testing, according to Kevin Unangst, a senior director in Microsoft's game unit.

The company is offering few details on Flight, but Unangst said that it … Read more
