Gunman 'Tentatively' Identified in Oregon Shooting













A masked gunman who opened fire in the crowded Clackamas Town Center mall in suburban Portland, Ore., killing two individuals before killing himself, has been "tentatively" identified by police, though they have not yet released his name.


The shooter, wearing a white hockey mask, black clothing, and a bullet proof vest, tore through the mall around 3:30 p.m. Tuesday, entering through a Macy's store and proceeding to the food court and public areas spraying bullets, according to witness reports.


Police have not released the names of the deceased. Clackamas County Sheriff's Department Lt. James Rhodes said authorities are in the process of notifying victims' families.


The injured victim has been transported to a local hospital, where she is "fighting for her life," according to Clackamas County Sheriff Craig Roberts.

Nadia Telguz, who said she was a friend of the injured victim, told ABC News affiliate KATU-TV in Portland that the woman was expected to recover.


"My friend's sister got shot," Teleguz told KATU. "She's on her way to (Oregon Health and Science University hospital). They're saying she got shot in her side and so it's not life-threatening, so she'll be OK."

911 Calls From New Jersey Supermarket Shooting Watch Video







Witnesses from the shooting rampage said that a young man who appeared to be a teenager ran through the upper level of Macy's to the mall food court, firing multiple shots, one right after the other, with what is believed to be a black, semi-automatic rifle.


More than 10,000 shoppers were at the mall during the day, police said. Roberts said that officers responded to the scene of the shooting within minutes, and four SWAT teams swept the 1.4 million-square-foot building searching for the shooter. He was eventually found dead, an apparent suicide.


"I can confirm the shooter is dead of an apparent self-inflicted gunshot wound," Rhodes said. "By all accounts there were no rounds fired by law enforcement today in the mall."


Roberts said more than 100 law enforcement officers responded to the shooting, and at least four local agencies were working on the investigation, including the FBI and Bureau of Alcohol, Tobacco and Firearms, which is working to trace the shooter's weapon.

Roberts also said that shoppers, including two emergency room nurses and one physician who happened to be at the mall, provided medical assistance to victims who had been shot. Other shoppers helped escort individuals out of the mall and out of harm's way, he said.


"There were a huge amount of people running in different directions, and it was chaos for a lot of citizens, but true heroes were stepping up in this time of high stress," Roberts said. "E.R. nurses on the scene were providing medical care to those injured, a physician on the scene was helping provide care to the wounded."


Mall shopper Daniel Martinez told KATU that he had just sat down at a Jamba Juice inside the mall when he heard rapid gunfire. He turned and saw the masked gunman, dressed in all black, about 10 feet away from him.


"I just saw him (the gunman) and thought, 'I need to go somewhere,'" Martinez said. "It was so fast, and at that time, everyone was moving around."


Martinez said he ran to the nearest clothing store. As he ran, he motioned for another woman to follow; several others ran to the store as well, hiding in a fitting room. They stayed there for an hour and a half until SWAT teams told them it was safe to leave the mall.

'Biology is a manufacturing capability'









































Soon we'll be able to engineer living things with mechanical precision, says Tom Knight, father of synthetic biology












How is synthetic biology different from biotechnology?
The main difference is the degree of control. Engineers want their inventions to be as predictable and free from complexity as possible. That's what makes the approach of equipping living things with standardised DNA modules called BioBricks - of which some 15,000 are now available in an open-source registry - different from the prevailing biotechnological practice of inserting single genes randomly into living things. The key realisation is that biology is a manufacturing capability. We can have it build the things we want.












How do you feel when people call you the "father of synthetic biology"?
It's everyone's dream to see ideas that have become popular inspire research projects and students. I've been lucky to see both things happen through the International Genetically Engineered Machines (iGEM) competition for students, which I helped inaugurate in 2004.












The 2012 winners have just been announced. What entry among the hundreds submitted over the years has inspired you most?
A bacterium-based test that makes water samples change colour if arsenic is present at potentially dangerous levels. This combines an application that is socially valuable and responsible with impressive biology, some attention to economics and an ability to carry a project to a place, such as Bangladesh, where it works and is needed.












And what has the craziest entry been?
A project by artist Alexandra Daisy Ginsberg, in which she engineered E. coli to produce coloured pigments. The idea was to develop a daily probiotic drink that would show, by changing the colour of your poo, if you have an infection.












Can we control the potential risks created by engineering living things in this way?
Yes, I think so. Nature has the capacity to produce things far more dangerous than we can for now.












Where will synthetic biology be in 10 years?
It's very hard to tell. We tend to overestimate what will happen in five years and underestimate what happens in 10. I often make comparisons with the development of electronics from modular components, and I don't think we have any more of an idea what will happen than those who invented transistors in 1947. There was no way they could predict they'd end up in things called cellphones.












Now you are immersed in biology, what's your favourite microbe?
Mesoplasma florum, which was found on a lemon tree in Florida in 1984. It's to do with poo again - its natural habitat is the insect gut. It's almost the smallest free-living organism discovered, at the boundary of being alive, so as an organism to study to find out how organisms survive, it's ideal.












In your early career you worked on the internet's forerunner, ARPANET. What a shift.
I feel privileged to have witnessed revolution not once, but twice!

Number of fallen casement windows hits new high






SINGAPORE: The number of fallen windows has risen since 2010, with an average increase of eight to nine cases per year.

There were 50 cases in 2010, 58 cases in 2011 and 67 cases up till November this year.

A joint statement by the Building and Construction Authority (BCA) and Housing and Development Board (HDB) said the increase is largely due to the number of fallen casement windows.

Thirty-seven of them fell from January to November this year, the highest number of incidents compared to the past six years. Most fell as a result of corroded aluminium rivets.

BCA and HDB said these owners would have contravened the Retrofitting Order under the Building Control Act for failing to replace all aluminium rivets with stainless steel rivets.

They can face a penalty of up to S$5,000 and or a jail term of up to six months.

In addition, if a window falls due to lack of maintenance, they could face up to a maximum fine of S$10,000 and or a jail term of up to one year under the Building Maintenance and Strata Management Act.

To date, 113 people have been fined and 35 people prosecuted for fallen casement windows and failing to comply with the Retrofitting Order.

Another 70 have been fined and two prosecuted for fallen sliding windows as a result of failing to maintain the windows.

BCA is also conducting blitz window inspections at HDB blocks and private estates that had previous cases of fallen casement windows.

Out of 100 units that BCA had inspected in Jurong and Jalan Rajah recently, 12 units had not retrofitted their casement windows with stainless steel rivets.

The owners of these units were subsequently issued composition fines.

BCA would like to remind homeowners to take windows safety seriously to prevent them from falling from height.

New Twitter (with filters) not available yet for iPhone



Twitter on Monday released a new version of its mobile app that allows users to filter their photos, a step that directly challenges Instagram. However, while Twitter said the version would be available for both Android and iPhone, the iPhone version has yet to appear in the App Store.

Twitter)



Twitter said today that it was releasing a new version of its iPhone and
Android apps that would allow users to filter their photos directly from their devices, a move that directly challenges Instagram's stranglehold on artistic photo sharing. But while the new Android version is already available, the iPhone version is not.


In its blog post announcing the new versions, Twitter said that, "Starting today, you'll be able to edit and refine your photos, right from Twitter. The latest versions of Twitter for iPhone and Twitter for Android introduce a few new ways to enhance the images you tweet." The move had been expected since word leaked out this weekend that the new features were imminent.


Later in the post, Twitter included a link to download the new version from Google Play and Apple's App Store. But the iPhone version isn't available using that method, nor by going directly to the App Store. The most recent version available through the App Store was released on November 15.


Twitter did not immediately respond to a request for comment tonight.


It seems possible that Twitter had every intention of releasing both new versions today, but that Apple held up the iPhone version for some reason. Either way, though, iPhone users hoping to be able to use Twitter's app to filter photos -- and share them -- are going to have to wait.


Twitter's move to release a new version of its mobile app that lets users filter their photos is its latest salvo in the ongoing, and intensifying, battle between Twitter and Instagram. For months, the two services have been picking away at features that made their apps work together. Most recently, Instagram disabled Twitter cards, meaning that photos created in Instagram can no longer be viewed in tweets.


In explaining that move, Instagram CEO Kevin Systrom said that he wants his users to focus more on using that service on the Web. But it's also clear he -- and perhaps Facebook, which bought Instagram earlier this year -- wants to wean the service's users off of Twitter.


The new version of Twitter for iPhone is likely to be available in a matter of hours. But it's odd that more than eight hours after announcing the new tool, the updated app has yet to be appear on the App Store.

U.K. Dash for Shale Gas a Test for Global Fracking

Thomas K. Grose in London


The starting gun has sounded for the United Kingdom's "dash for gas," as the media here have dubbed it.

As early as this week, a moratorium on shale gas production is expected to be lifted. And plans to streamline and speed the regulatory process through a new Office for Unconventional Gas and Oil were unveiled last week in the annual autumn budget statement by the chancellor of the exchequer, George Osborne.

In the U.K., where all underground mineral rights concerning fossil fuels belong to the crown, hydraulic fracturing, or fracking, could unlock a new stream of government revenue as well as fuel. But it also means that there is no natural constituency of fracking supporters as there is in the United States, birthplace of the technology. In the U.S., concerns over land and water impact have held back fracking in some places, like New York, but production has advanced rapidly in shale basins from Texas to Pennsylvania, with support of private landowners who earn royalties from leasing to gas companies. (Related: "Natural Gas Stirs Hope and Fear in Pennsylvania")

A taste of the fight ahead in the U.K. came ahead of Osborne's speech last weekend, when several hundred protesters gathered outside of Parliament with a mock 23-foot (7-meter) drilling rig. In a letter they delivered to Prime Minister David Cameron, they called fracking "an unpredictable, unregulatable process" that was potentially toxic to the environment.

Giving shale gas a green light "would be a costly mistake," said Andy Atkins, executive director of the U.K.'s Friends of the Earth, in a statement. "People up and down the U.K. will be rightly alarmed about being guinea pigs in Osborne's fracking experiment. It's unnecessary, unwanted and unsafe."

The government has countered that natural gas-fired power plants would produce half the carbon dioxide emissions of the coal plants that still provide about 30 percent of the U.K.'s electricity. London Mayor Boris Johnson, viewed as a potential future prime minister, weighed in Monday with a blistering cry for Britain to "get fracking" to boost cleaner, cheaper energy and jobs. "In their mad denunciations of fracking, the Greens and the eco-warriors betray the mindset of people who cannot bear a piece of unadulterated good news," he wrote in the Daily Telegraph. (Related Quiz: "What You Don't Know About Natural Gas")

Energy Secretary Edward Davey, who is expected this week to lift the U.K.'s year-and-a-half-old moratorium on shale gas exploration, said gas "will ensure we can keep the lights on as increasing amounts of wind and nuclear come online through the 2020s."

A Big Role for Gas

If the fracking plan advances, it will not be the first "dash for gas" in the U.K. In the 1980s, while Prime Minister Margaret Thatcher battled with mining unions, she undercut their clout by moving the nation toward generating a greater share of its electricity from natural gas and less from coal. So natural gas already is the largest electricity fuel in Britain, providing 40 percent of electricity. (Related Interactive: "World Electricity Mix")

The United Kingdom gets about 10 percent of its electricity from renewable energy, and has plans to expand its role. But Davey has stressed the usefulness of gas-fired plants long-term as a flexible backup source to the intermittent electricity generated from wind and solar power. Johnson, on the other hand, offered an acerbic critique of renewables, including the "satanic white mills" he said were popping up on Britain's landscape. "Wave power, solar power, biomass—their collective oomph wouldn't pull the skin off a rice pudding," he wrote.

As recently as 2000, Great Britain was self-sufficient in natural gas because of conventional gas production in the North Sea. But that source is quickly drying up. North Sea production peaked in 2000 at 1,260 terawatt-hours (TWH); last year it totaled just 526 TWh.

Because of the North Sea, the U.K. is still one of the world's top 20 producers of gas, accounting for 1.5 percent of total global production. But Britain has been a net importer of gas since 2004. Last year, gas imports—mainly from Norway, Belgium, and the Netherlands—accounted for more than 40 percent of domestic demand.

The government hopes to revive domestic natural gas production with the technology that has transformed the energy picture in the United States—horizontal drilling into deep underground shale, and high-pressure injection of water, sand, and chemicals to create fissures in the rock to release the gas. (Related Interactive: "Breaking Fuel From the Rock")

A Tougher Road

But for a number of reasons, the political landscape is far different in the United Kingdom. Britain made a foray into shale gas early last year, with a will drilled near Blackpool in northwest England. The operator, Cuadrilla, said that that area alone could contain 200 trillion cubic feet of gas, which is more than the known reserves of Iraq. But the project was halted after drilling, by the company's own admission, caused two small earthquakes. (Related: "Tracing Links Between Fracking and Earthquakes" and "Report Links Energy Activities To Higher Quake Risk") The April 2011 incident triggered the moratorium that government now appears to be ready to lift. Cuadrilla has argued that modifications to its procedures would mitigate the seismic risk, including lower injection rates and lesser fluid and sand volumes. The company said it will abandon the U.K. unless the moratorium is soon lifted.

A few days ahead of Osborne's speech, the Independent newspaper reported that maps created for Britain's Department of Energy and Climate Change (DECC) showed that 32,000 square miles, or 64 percent of the U.K. countryside, could hold shale gas reserves and thus be open for exploration. But a DECC spokeswoman said "things are not quite what it [the Independent story] suggests." Theoretically, she said, those gas deposits do exist, but "it is too soon to predict the scale of exploration here." She said many other issues, ranging from local planning permission to environmental impact, would mean that some tracts would be off limits, no matter how much reserve they held. DECC has commissioned the British Geological Survey to map the extent of Britain's reserves.

Professor Paul Stevens, a fellow of the Royal Institute of International Affairs, said the U.K. is clearly interested in trying to replicate America's shale gas revolution. "That's an important part of the story," he said, but trying to use the American playbook won't be easy. "It's a totally different ballgame." In addition to the fact that mineral rights belong to the crown, large expanses of private land that are commonplace in America don't exist in England. Just as important, there is no oil- and gas-service industry in place in Britain to quickly begin shale gas operations here. "We don't have the infrastructure set up," said Richard Davies, director of the Durham Energy Institute at Durham University, adding that it would take years to build it.

Shale gas production would also likely ignite bigger and louder protests in the U.K. and Europe. "It's much more of a big deal in Europe," Stevens said. "There are more green [nongovernmental organizations] opposed to it, and a lot more local opposition."

In any case, the U.K. government plans to move ahead. Osborne said he'll soon begin consultations on possible tax breaks for the shale gas industry. He also announced that Britain would build up to 30 new natural gas-fired power plants with 26 gigawatts (GW) of capacity. The new gas plants would largely replace decommissioned coal and nuclear power plants, though they would ultimately add 5GW of additional power to the U.K. grid. The coalition government's plan, however, leaves open the possibility of increasing the amount of gas-generated electricity to 37GW, or around half of total U.K. demand.

The U.S. Energy Information Administration (EIA) estimates that Europe may have as much as 600 trillion cubic feet of shale gas that could be recovered. But Stevens said no European country is ready to emulate the United States in producing massive amounts of unconventional gas. They all lack the necessary service industry, he said, and geological differences will require different technologies. And governments aren't funding the research and development needed to develop them.

Globally, the track record for efforts to produce shale gas is mixed:

  • In France, the EIA's estimate is that shale gas reserves total 5 trillion cubic meters, or enough to fuel the country for 90 years. But in September, President Francois Hollande pledged to continue a ban on fracking imposed last year by his predecessor, Nicolas Sarkozy.
  • Poland was also thought to have rich shale gas resources, but initial explorations have determined that original estimates of the country's reserves were overstated by 80 percent to 90 percent. After drilling two exploratory wells there, Exxon Mobil stopped operations. But because of its dependence on Russian gas, Poland is still keen to begin shale gas production.
  • South Africa removed a ban on fracking earlier this year. Developers are eyeing large shale gas reserves believed to underlie the semidesert Karoo between Johannesburg and Cape Town.
  • Canada's Quebec Province has had a moratorium on shale gas exploration and production, but a U.S. drilling company last month filed a notice of intent to sue to overturn the ban as a violation of the North American Free Trade Agreement.
  • Germany's Environment Ministry has backed a call to ban fracking near drinking water reservoirs.
  • China drilled its initial shale gas wells this year; by 2020, the nation's goal is for shale gas to provide 6 percent of its massive energy needs. The U.S. government's preliminary assessment is that China has the world's largest "technically recoverable" shale resources, about 50 percent larger than stores in the United States.

Woman Gets Life for Lottery Winner's Murder













DeeDee Moore, the Tampa woman accused of swindling and then killing lottery winner Abraham Shakespeare, was found guilty today of first degree murder and other charges, after she declined to take the stand and the defense rested without calling a single witness.


In addition to the murder charge, Moore was also found guilty of possessing and discharging a firearm resulting in death. Prosecutors did not pursue the death penalty in the case, and Moore was sentenced to life in prison without parole.


"After trial and listening to all of this over two weeks, words that were said cool, calculated, manipulated. Abraham Shakespeare was your prey and victim. Money was the route of evil you brought to Abraham. You are sentenced to life in prison you shall not be elegible for parole," Judge Emmet Battles said.


Jurors deliberated for more than three hours Monday before delivering their verdict.


Prosecutors argued that Moore, 40, befriended Shakespeare before he vanished in April 2009 after he'd won $30 million in the Florida lottery. After Shakespeare had given away most of his money to people who simply asked for it, Moore agreed to manage the little he had left, but instead, prosecutors said, stole his winnings and killed him.


During a dramatic trial Moore has broken down in tears several times, and at one point said that she went into anaphylactic shock while in custody after taking the drug Bactrim when she was having problems with cuts on her ankles from being cuffed every day.


Early today the defense announced it would rest its case without calling any witnesses. Moore did not testify during her trial.

Dee Dee Moore Trial: Woman Accused of Murdering Lottery Winner Watch Video





"There is no witness that can say she ever admitted to doing the killing or participating as a principle in helping anyone else do the killing," Moore's defense attorney Byron Hileman said today.


In the courtroom this morning, Moore's friend, former inmate Rose Condora was accused of threatening witnesses by Tampa Judge Emmett Battles, and was thrown out of the courtroom.


Authorities say Shakespeare, 47, was shot twice in the chest by a .38-caliber pistol sometime in April 2009. He wasn't reported missing until November 2009. His body was found under a slab of cement in a backyard in January 2010.


Polk County authorities claim Moore offered someone a $200,000 house in exchange for reporting a false sighting of Shakespeare. She also allegedly sent the victim's son $5,000 in cash for his birthday, and used the victim's cellphone to send text messages purportedly from him.


Shakespeare's mother, Elizabeth Walker, also testified that Moore tried to hide that her son was missing, and said that he had AIDS.


Sentorria Butler, Shakespeare's ex-girlfriend and the mother of his child, also testified. Butler told the court last week that Moore is a divisive and manipulative woman who told her Shakespeare "ran off with the lady from the bank."


During the trial, jurors also watched a Walmart surveillance video that the prosecution said links Moore to Shakespeare's killing. The footage shows Moore making a $104 cash purchase of gloves, duct tape, plastic sheeting and other items detectives later found close to where Shakespeare's body was buried.


Jurors hearing the case also heard a rambling two-page letter that witness Greg Smith, a police informant who was a former friend of Shakespeare and supposed friend of Moore, says Moore allegedly forged while at a Comfort Inn & Suites in Lakeland, Fla.


The letter was meant to appear to be from Shakespeare, prosecutors said. They say the letter was a ruse to convince Shakespeare's mother that he was still alive. Moore attempted to cover her tracks while it was written, according to prosecutors.


During the trial, jurors had to be accompanied by a security escort into the courtroom after they told the judge Smith and Shakespeare's family and friends were making them feel uncomfortable outside the courthouse. None of the jurors had to be excused by the judge.

Female lemurs avoid the wrong love in the dark



































IT IS the ultimate voice-recognition system. Without ever meeting him, a female lemur still knows the call of her father.












The ability to identify family members is important to avoid inbreeding. For large-brained mammals like apes that engage in complex social interactions this is relatively straightforward. Now, a team has shown that nocturnal grey mouse lemurs appear to do the same, even though lemurs are reared exclusively by their mothers (BMC Ecology, doi.org/jvx).












Study leader Sharon Kessler of Arizona State University in Tempe, believes that the young lemurs may associate calls similar to their own, or to those of male siblings, with their fathers.

N. Korea extends rocket launch window






SEOUL: North Korea on Monday extended the window for its planned rocket launch by one week, in order to deal with a "technical deficiency" with the first stage of the carrier.

The original December 10-22 window was extended to December 29, the Korean Committee of Space Technology said in a statement carried by the official Korean Central News Agency.

The statement stressed that scientists and technicians were still "pushing forward" with preparations for the mission, which has been widely condemned by the international community.

"They, however, found technical deficiency in the first-stage control engine module of the rocket... and decided to extend the launch period," it said.

North Korea says the rocket launch is a peaceful mission aimed at putting a satellite in orbit.

The United States and its allies view it as a disguised ballistic missile test banned under UN resolutions prompted by the North's nuclear tests in 2006 and 2009.

Five lies your TV salesperson will tell you



Using the time-honored tactics of obfuscation, misdirection, and a little bit of fear, the people who try to sell you TVs can hit you with some heavy-duty lies.


Now this isn't to say that all TV sales people are bad, nor that any necessarily do this out of malice (there's plenty of misinformation out there confused as truth). But when it's your dollar on the line, being prepared with some facts can only be a good thing.



For a primer on all the jargon, check out "TV tech explainer: Every HDTV technology decoded."


'This TV has a million-to-one contrast ratio.'
No, it doesn't. Every TV manufacturer lies about contrast ratio. Not a single one is remotely accurate. So it's impossible to prescribe an exact number to any TV given only the manufacturers data. The fact is, plasmas have better native contrast ratios than LCDs (LED or otherwise). There are three local-dimming LED LCDs on the market this year (Elite by Sharp, Sony HX950, and LG LM9600), and they're all extremely expensive. These offer similar contrast ratios than the best plasmas, though not exactly. For more info, check out "Contrast ratio (or how every TV manufacturer lies to you)."


'This TV has better sound.'
You know what, let's say they're right. Let's say TV A has better sound than TV B. The fact is, no TV sounds good. So all they're really saying is, "This TV sounds less bad than this other TV."


The thinness that we all love in flat-panel TVs means the speaker drivers by their very nature have to be very small. Small drivers can't do much to create sound waves.


The wiser salespeople will direct you towards a sound bar or other home audio system. This is definitely where you should spend a few dollars. Pretty much every sound bar will sound better than the TV speakers, and the better sound bars actually sound pretty good.


Check out CNET's page on the best home audio and best sound bars.



'TVs break all the time. You need an extended warranty.'
Another example of this is "I see TVs come in for repair all the time." From a rhetorical standpoint, this is a rather brilliant argument. This person works at the store. They see lots of TVs coming in for repair. So as an "authority," this seems a valid point.


Except, it isn't.


What the salesperson isn't seeing, is all the TVs that don't come in for repair. Which is most of them. Flat-panel TVs are very reliable, so an extended warranty is a largely a waste of money.


'LED TVs have the best picture quality.'
Nope. First of all, there's no such thing as an "LED TV." Every
LED TV is just a standard LCD TV that uses LEDs to create light instead of the "old-fashioned" cold-cathode fluorescent lamps (CCFL). LCDs have their positives, like light output and lower energy consumption, but when it comes to a direct picture quality comparison, plasmas have better black levels, better contrast ratios, and better viewing angles (for those not sitting directly in front of the TV). For example, four of the five TVs CNET picked for best picture quality are plasmas (the one LED LCD is also the most expensive TV you can buy per-screen-inch).


There's more to it than that, as I lay out in "Why LED does not mean a better picture" and "LED LCD vs. plasma vs. LCD."


'If you want the best picture and sound, you need the best HDMI cable.'
This is the one that annoys me the most, and I've written four articles about it for CNET alone. This is the one that eliminates any guilt I have impugning the good name of some hard-working salespeople. There is no picture or sound quality difference between any HDMI cable. None. At all. So if you spend $3 or $300, the image and sound will be 100 percent exactly the same.


I could talk about this forever, and indeed I have. Check out "Why all HDMI cables are the same,"
"Why all HDMI cables are the same, Part 2,"
"Still more reasons why all HDMI cable are the same," and the "HDMI cable buying guide."


Bottom line



It is difficult to get a man to understand something, when his salary depends upon his not understanding it! -- Upton Sinclair



But look, be polite. Don't waste someone's time. This goes for both sides. They're just trying to make a living, you're just trying to keep as much of your living as possible. When I sold electronics at Circuit City, I was given all sorts of information, presented as truth, to tell customers. Much of which I know now to be false, or at least "truth adjacent." But as an 18-year-old, long haired (yep, believe it), wannabe guitar god, I didn't know any better. So give the poor guy or gal the benefit of the doubt that they're not knowingly lying to you.



Except for that HDMI cable stuff; man that bugs me.



How about you? Been told any doozys?




Got a question for Geoff? Send him an e-mail! If it's witty, amusing, and/or a good question, you may just see it in a post just like this one. No, he won't tell you which TV to buy. Yes, he'll probably truncate and/or clean up your e-mail. You can also send him a message on Twitter: @TechWriterGeoff.

Plants Grow Fine Without Gravity


When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.
