Galaxy Nexus and other CDMA devices removed from Google Support pages

Verizon Galaxy Nexus
Some of you may have noticed that the Verizon version of the Galaxy Nexus is no longer listed as a supported, official developer device by Google. Despite rumors to the contrary, it doesn't appear this has anything to do with the kerfuffle over Wallet, but instead centers around technical issues relating to the APK files required for CDMA connectivity and the signing of those libraries. Other devices have also disappeared from the support pages, including the Nexus S 4G and the Verizon-branded Xoom. Google has posted an update explaining that, "for various technical reasons" CDMA telephony is handled by binaries provided by the carrier in newer devices. The result is different signatures being associated with those APKs than a pure AOSP builds and, thus, those essential components don't function properly.

Google explained the disappearance by saying "we aim to make sure that we are as clear as possible about the degree of support that devices have," before going on to promise all Nexus devices would continue to have unlockable bootloaders and that as many of the closed-source binaries as possible would be made available. For the complete statement hit up the source link.

Scientists reveal secret of humongous mammals

How did some mammals get so big? A new study calculates the rate at which mammals evolved from?mouse-sized to elephant-sized.?

Within as little as 24 million generations, mammals can evolve from the size of a mouse to the size of an elephant, a new study estimates.

Skip to next paragraph

This calculation is based on the most rapid increase in size seen in the fossil record after?a mass extinction?wiped out their much larger competitors, the dinosaurs. They also found animals can shrink more than 10 times as fast as they can grow to giant sizes.

"What we wanted to know is how quickly could they evolve from these tiny, scampering mammals to the behemoths of the land we see now," Alistair Evans, the lead study researcher and an evolutionary biologist at Monash University in Australia wrote in an email to LiveScience. "It's a classic story of taking advantage of a new opportunity ? the vacant landscape?devoid of dinosaurs."

At the end of the Cretaceous Period, about the time the dinosaurs disappeared, mammals were small ? the largest ones appear to have been rodent-like creatures about the size of rabbits, weighing about 6.6 lbs. (3 kilograms).

Within about 40 million years, the largest land mammal ever to live had emerged: the?Indricotherium.

Related to horses and rhinos, the tusked, tree-leaf-eating?Indricotherium?is estimated to have weighed as much as 33,000 lbs. (15,000 kg), according Evans.

Evans and his colleagues looked at size changes within 28 groups of mammals, called orders of mammals, on four continents and all ocean basins. They found a discrepancy between the rate of change within species and the rate of change within higher level groups that include many species, such as orders. Within species, change happens more quickly, but these rates do not last for long.

If they did, the team calculates that mammals could go from mouse-size to elephant-size in 200,000 generations. However, the fossil record demonstrates large-scale changes don't happen this quickly, according to Evans.

While?mammals got steadily bigger?after the dinosaurs disappeared, the rates at which they did so varied among the groups.

The fastest group was the cetaceans, or aquatic mammals, such as whales and dolphins, which became bigger at about twice the rate of land-dwelling mammals. Cetaceans' ancestors were originally land-dwelling, and the switch to water most likely encouraged them to grow rapidly, since they no longer needed to support their own weight and because large size helps prevent the loss of body heat in water, according to Evans.

'Soul Train' creator commits suicide

By Msnbc.com staff and wire

Don Cornelius, creator of the long-running?TV dance?show "Soul Train," is dead at 75 of a self-inflicted gunshot wound, Los Angeles police tell the Associated Press.

Cornelius' death?was?discovered early Wednesday morning at his Sherman Oaks, Calif. home.

Us Weekly reports that when Cornelius was in court in 2009 for divorce proceedings, he complained of "significant health issues."

TheGrio: Why 'Soul Train; will never leave America's station

"Soul Train" began in 1970 in Chicago and aired in syndication?from 1971 to March 2006, featuring primarily African-American musicians. It brought the best R&B, soul and later hip-hop acts to TV and had teenagers dance to them. It was one of the first shows to showcase African-Americans prominently, although the dance group was racially mixed. Cornelius was the first host and executive producer.

Stars such as Ike and Tina Turner, Marvin Gaye, Aretha Franklin, the Jackson 5, James Brown and Stevie Wonder appeared on the show.

Watching the show became a weekly ritual in many households, especially African-American homes. Author Earl Ofari Hutchinson wrote in theGrio that "It was virtually a black household ritual to do one of two things when Saturday rolled around and it was Soul Train time. One was to sway, swoon, and sing the lyrics belted out by the parade of R&B legends and top hit artists ... The other ritual was to dance, or more likely stumble around the living room, trying to do our best imitation of the latest dance steps displayed by the show's perpetual motion gyrating couples."

Popular features on the show included the?"Soul Train Line,"?where individual dancers showed off their moves between two lines of people, and the "Soul Train Scramble Board," where dancers unscrambled letters that spelled the name of that night's performer or a prominent African-American.

The show began each episode by welcoming viewers to "the hippest trip in America" and closed by wishing them "love, peace and soul."

Pentagon: Army, Marines to shrink as budget slows (AP)

WASHINGTON ? The Pentagon outlined a plan Thursday for slowing the growth of military spending, including cutting the size of the Army and Marine Corps, retiring older planes and trimming war costs. It drew quick criticism from Republicans, signaling the difficulty of scaling back defense budgets in an election year.

The changes Defense Secretary Leon Panetta described at a news conference are numerous but hardly dramatic. They aim to save money by delaying some big-ticket weapons like a next-generation nuclear-armed submarine, but the basic shape and structure of the military remains the same.

The Army would shrink from a peak of 570,000 to 490,000 within five years, and the Marines would drop by 20,000, to 182,000. Those are considerable declines, but both services will still be slightly larger than on 9/11, before they began a decade of war. Both will keep their footholds abroad, although the Army will decrease its presence in Europe and the Marines plan to increase theirs in Asia.

Panetta said the administration will ask Congress for $525 billion to run the Pentagon in 2013 ? $6 billion less than the current budget. War costs, which are not considered part of the base budget, would decline from $115 billion to $88 billion, reflecting the completion of the U.S. withdrawal from Iraq.

The base budget would then increase in each year of the Pentagon's five-year plan, reaching $567 billion in 2017. A year ago the Pentagon had projected 2017 spending to reach $622 billion. The Pentagon counts those reductions in projected future spending as "defense savings."

When Obama took office in January 2009 the Pentagon's base budget was $513 billion. In 2001 it was $297 billion.

Under a budget deficit-cutting deal Congress made last summer, the Pentagon is committed to reducing projected spending by $487 billion over the next 10 years. The plan Panetta presented Thursday covers the first five years of that span and would cut a cumulative total of $259 billion in planned spending.

"We believe this is a balanced and complete package," Panetta said.

In a bid to pre-empt election-year Republican criticism, Panetta said the plan begins to shift the Pentagon's focus from the long wars in Iraq and Afghanistan to future challenges in Asia, the Mideast and in cyberspace. More special operations forces like the Navy SEALs who killed Osama bin Laden will be available around the world, he said, and the Pentagon will stress improvements in cyberdefenses.

Republicans were quick to pounce on the proposed Army and Marine Corps reductions.

"These cuts reflect President Obama's vision of an America that is weakened, not strengthened, by our men and women in uniform," said Rep. Howard "Buck" McKeon, R-Calif., chairman of the House Armed Services Committee.

McKeon voted for the bill last August that established the requirement for $487 billion in defense savings over five years.

"Taking us back to a pre-9/11 military force structure places our country in grave danger," said Sen. John Cornyn, R-Texas, a member of the Senate Armed Services Committee that will hold hearings on the Pentagon budget plan.

Sen. John McCain, R-Ariz., said the Panetta plan "ignores the lessons of history." He said it provides for a military that is "too small to respond effectively to events that may unfold over the next few years."

The military's top general, however, defended the administration's approach. Army Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, said he is convinced that the risks raised by cutting the size of the military are manageable. He said failing to make these changes would have meant even bigger risks.

"This budget is a first step ? it's a down payment ? as we transition from an emphasis on today's wars to preparing for future challenges," he said, adding, "This budget does not lead to a military in decline."

Among other details Panetta disclosed:

--The Air Force would retire some older planes including about two dozen C-5A cargo aircraft and 65 of its oldest C-130 cargo planes.

-- The Navy would keep a fleet of 11 aircraft carriers but retire seven cruisers earlier than planned. It also would delay purchase of some other ships, including a new Virginia-class submarine.

--Purchase of F-35 stealth fighter jets, to be fielded by the Air Force, Navy and Marine Corps, would be slowed.

--Current plans for building a new generation of submarines that carry long-range nuclear missiles would be delayed by two years. The current fleet of nuclear-capable bombers and land-based nuclear missiles would be left unchanged.

--Military pay raises will remain on track until 2015, when the pace of increase will be slowed by an undetermined amount.

--Obama will ask Congress to approve a new round of domestic base closures, although the timing of this was left vague and there is little chance that lawmakers would agree to this in a presidential election year.

The defense spending plan is scheduled to be submitted to Congress as part of the administration's full 2013 budget on Feb. 13.

The defense budget is being reshaped in the midst of a presidential contest in which Obama seeks to portray himself as a forward-looking commander in chief focusing on new security threats. Republicans want to cast him as weak on defense.

Obama has highlighted his national security successes ? the killing of bin Laden, the death of other senior al-Qaida leaders and the demise of Libya's Moammar Gadhafi ? to counter Republican criticism. He also has emphasized the completion of the U.S. troop withdrawal from Iraq and the start of a drawdown in Afghanistan as turning points that offer new opportunities to scale back defense spending.

But several congressional Republicans see a political opening in challenging the reductions in projected military spending that the GOP and Obama agreed to last summer as part of a deal to raise the nation's borrowing authority. They've echoed Obama's potential presidential rivals Mitt Romney, Newt Gingrich and Rick Santorum, who plead for fiscal austerity but contend that sizable cuts would gut the military.

'Speed gene' in modern racehorses originated from British mare 300 years ago, scientists claim

ScienceDaily (Jan. 24, 2012) ? Scientists have traced the origin of the 'speed gene' in Thoroughbred racehorses back to a single British mare that lived in the United Kingdom around 300 years ago, according to findings published today in the scientific journal Nature Communications.

The origin of the 'speed gene' (C type myostatin gene variant) was revealed by analysing DNA from hundreds of horses, including DNA extracted from the skeletal remains of 12 celebrated Thoroughbred stallions born between 1764 and 1930.

"Changes in racing since the foundation of the Thoroughbred have shaped the distribution of 'speed gene' types over time and in different racing regions," explained Dr Emmeline Hill, the senior author of the study, and a genomics scientist at the School of Agriculture and Food Science, University College Dublin.

"But we have been able to identify that the original 'speed gene' variant entered the Thoroughbred from a single founder, which was most likely a British mare about 300 years ago, when local British horse types were the preeminent racing horses, prior to the formal foundation of the Thoroughbred racehorse."

The international scientific team led by scientists from University College Dublin (UCD), Equinome Ltd and the University of Cambridge, have traced all modern variants of the original 'speed gene' to the legendary Nearctic (1954-1973), and attribute the wider expansion of these variants to Northern Dancer (1961-1990),the son of Nearctic, and one of the most influential stallions of modern times.

"Having first identified the 'speed gene' in 2010, we decided to see if we could trace the origin of the gene variant using population genetics coupled with pedigree analysis. We wanted to understand where speed in the Thoroughbred came from.," said Dr Hill.

Dr Hill is also a co-founder of Equinome, a UCD spin-out company headquartered at NovaUCD, which has developed The Equinome Speed Gene Test. This test is currently being used by the global bloodstock and racing industry to identify the optimum racing distance for individual Thoroughbred horses.

"We traced the economically valuable gene variant by determining 'speed gene' type in almost 600 horses from 22 Eurasian and North American horse breeds, museum bone and tooth specimens from 12 legendary Thoroughbred stallions, 330 elite performing modern Thoroughbreds from 3 continents, 40 donkeys and two zebras.," added Dr Hill.

According to co-author Dr Mim Bower from the University of Cambridge, UK, "The findings point to a British mare as the most likely single founder of the original 'speed gene' because one of the lines of evidence from the research demonstrated that the prize stallions of the 17th and 18th centuries had two copies of the T type speed gene variant (T:T) which is linked to greater stamina."

"At this time in the history of horse racing, races were between two horses competed over multiple heats, at distances of between two to four miles, and repeated until a horse had won the event twice or 'distanced' the opponent. Horses did not race until they were five or six years old, and then only two or three times in their lives. This is consistent with these horses being T:T types.," said Dr Bower

An increased premium on speed and precocity developed as two-year-old races became popular during the last century, and in many regions of the world, these preferences remain to this day.

Dr Hill explained, "For example, in Australia, the myostatin 'speed gene' type (C:C), which is best suited to fast, short-distance, sprint races, is more common and there is a market driven demand for horses with at least one copy of the C type gene variant."

"This just goes to show the power breeders have to shape the genetic make-up of their horses. Decisions regarding the race pattern in each racing jurisdiction and the commercial demand for certain types will also rapidly influence the genetic make-up of the population."

To identify where the C type gene variant originated, the researchers analysed DNA samples from more than 20 horse breeds that included representatives of local British and Irish horses, from where female Thoroughbred lineages derive, and exotic eastern populations from where male Thoroughbred lineages derive.

The study identified the Shetland breed as having the highest frequency of the C type gene variant. The Shetland represents local British horse types, which were the preeminent racing horses prior to the formal foundation of the Thoroughbred.

By comparing the diversity of the chromosomes around the C and T type gene variants researchers found only a single C type compared to 11 different T type gene variants, meaning that the 'speed gene' entered the Thoroughbred just once.

"The results show that the 'speed gene' entered the Thoroughbred from a single founder, which was most likely a British mare about 300 years ago when local British horse types were the preeminent racing horses, prior to the formal foundation of the Thoroughbred racehorse.," said Dr Hill.

Collaborators in the study were scientists from Trinity College Dublin, the Russian Academy of Sciences and the Swedish University of Agricultural Sciences. The research was supported by grants from The Horserace Betting Levy Board, Leverhulme Trust, Cambridge Overseas Trust and Science Foundation Ireland.
