I've always heard that smell plays an important role in how food tastes. I didn't expect that color could also sway the taste buds. A study published in the Journal of Sensory Studies found that the color of a cup can influence the way people taste hot chocolate.

Betina Piqueras-Fiszman, a researcher at the Polytechnic University of Valencia in Spain, and Charles Spence, a professor at the University of Oxford in England, subjected 57 participants to what may be one the tastiest science experiments ever.

The participants tasted samples of hot chocolate served in four different colors of plastic cups: white, cream, red, and orange. The sippers preferred the flavor of the beverage in orange or cream-colored cups.

So why did orange and cream set themselves apart from white and red? It's a bit mysterious, but it definitely involves the way the brain processes visual information and allows it to influence our sense of taste.

"These results should hopefully help stimulate chefs, restaurateurs, and those working in the food and beverage packaging sectors to think more carefully about the color of their plateware/packaging and its potential effects on their customers' perception of the taste/flavor of the products that they happen to be serving/delivering to market," the researchers write.

There has already been research into how the color of food itself impacts our taste. A 2007 study in the Journal of Consumer Research showed that the color of orange juice had a greater impact on taste perception than actual differences in samples. What's intriguing about this latest study is how the color of the packaging impacts our taste perceptions.

The taste challenge
Not one to shy away from a science challenge, I took it upon myself to become a guinea pig and tackle this important issue head-on. I raided the cabinet for Fiestaware, coming up with mugs in the colors of red, blue, and orange.

I prepared two packets of Starbucks-brand hot cocoa in double chocolate flavor in a 2-cup measuring cup. I poured an equal amount into each mug. Sipping them thoughtfully, I thought I detected a greater smoothness and sweetness in the hot chocolate that was gently steaming in the orange mug.

The problem with my findings is that I already knew the results of the study. I needed an unwitting test subject, so I called the one person I know who is a hot chocolate connoisseur... my mother.

My mom came over and tasted the hot chocolate from each cup. She considered the flavors. She thought the red mug tasted a bit bitter. She thought the blue was nicely chocolatey. Her favorite, though, was the hot chocolate in the orange mug.

Sure, my test sample size is incredibly small, but the orange mug is the clear winner of my mini-experiment. I also learned something very important today. Science is delicious.

The taste test requires deep contemplation.

Obama Poised to Name New Defense, Treasury Chiefs

With the "fiscal cliff" crisis behind him, President Obama is poised to name two new key players to his cabinet, with both announcements expected to come next week.

Obama will name the replacement for outgoing Defense Secretary Leon Panetta as soon as Monday, sources told ABC News. Former Republican Sen. Chuck Hagel is the likely nominee, they said.

Meanwhile, the president is also eyeing a replacement for outgoing Treasury Secretary Timothy Geithner, the longest-serving member of Obama's first-term economic team and one-time lead negotiator for the administration in the "fiscal cliff" talks.

Current chief of staff Jack Lew is all but certain to get the nod for Treasury, according to people familiar with Obama's thinking.

A White House spokesman cautioned that the president has not yet made a final decision on either post, calling reports about Hagel and Lew "merely guessing."

Still, when Obama returns from his Hawaiian vacation on Sunday, he's expected to waste little time filling out his team for a second term.

Geithner has said he would remain at his post "until around the inauguration" Jan. 20, a Treasury spokesperson noted Thursday, putting the department potentially in transition just as the administration confronts the next "cliffs" over the automatic spending cuts and nation's debt limit.

During an appearance on ABC's "This Week" in April, Geithner said the next Treasury secretary would need to be someone who is "willing to tell [Obama] the truth and, you know, help him do the tough things you need to do."

Lew, a former two-time Office of Management and Budget director and trusted Obama confidant who has held the chief of staff role since early 2012, is the front-runner for the job.

Meanwhile, Sen. John Kerry -- Obama's nominee to replace outgoing Secretary of State Hillary Clinton -- has begun making more regular appearances at the U.S. State Department before his expected confirmation later this month.

His Senate hearings are set to begin shortly after Obama's inauguration, sources say. The administration still expects Clinton to testify about the Sept. 11 Benghazi, Libya, attacks before Kerry is confirmed.

But it is the potential nomination of Republican Hagel that has caused the most stir.

Critics from across the political spectrum have taken aim at the former senator from Nebraska's record toward Israel and what some have called a lack of experience necessary to lead the sprawling Pentagon bureaucracy or its operations. The controversy has set the stage for what would be a contentious confirmation process.

"A lot of Republicans and Democrats are very concerned about Chuck Hagel's position on Iran sanctions, his views toward Israel, Hamas and Hezbollah, and that there is wide and deep concern about his policies," Sen. Lindsey Graham, R-S.C., told "Fox News Sunday."

He would not say whether Republicans felt so strongly as to expect a filibuster of the nomination.

"I can tell you there would be very little Republican support for his nomination," Graham said. "At the end of the day, they will be very few votes."

Still, Hagel, 66, a former businessman and decorated veteran who served in the Vietnam War, has won praise and admiration from current and former diplomats for his work on Obama's Intelligence Advisory Board and Panetta's Policy Advisory Board.

Unique meteorite hints Mars stayed moist for longer

A scorched rock bought in Morocco turned out to be a diamond in the rough. The unusual meteorite may be the first sample of the Red Planet's crust ever to hit Earth, and it suggests that Mars held on to its water for longer than we thought.

The meteorite, dubbed Northwest Africa (NWA) 7034, is strikingly different from the 111 previously discovered Martian meteorites. "You could look at meteorites for the rest of your life and not find another one like this," says Carl Agee of the University of New Mexico in Albuquerque, who was part of a team that has recently analysed NWA 7034. "This is in its own new group."

The most distinctive difference is its mineral content. Previously found meteorites had unearthly oxygen isotopes that marked them as being from another planet, and their volcanic origin made Mars the most likely culprit. But compared to these meteorites, surface rocks studied by Martian rovers and orbiters are much richer in light metals such as potassium and sodium. This suggests the known meteorites came from deeper inside the Red Planet.

"We're watching data coming back from Mars, and everything that comes back doesn't look like the Martian meteorites we have in our collections," says Munir Humayun of Florida State University in Tallahassee, who was not involved in the new study. "That's kind of a bummer."

By contrast, NWA 7034's chemistry closely resembles the rock and soil studied by NASA's Spirit rover. Preliminary measurements from the Curiosity rover, which landed in August 2012, suggest its landing site also has a similar composition.

Drying era

"Finally, it looks as if we have a sample that is very similar to the rocks that the rovers are seeing," Agee says. What's more, the Moroccan meteorite may come from a period in Mars' history when the planet was drying out.

Mars is thought to have once been much warmer, wetter and more hospitable to life. Then it morphed into the dry, cold desert we see today. The oldest known Mars meteorite, called the Allan Hills meteorite, is 4.5 billion years old. The other 110 meteorites are much younger – 1.5 billion years old at most – and formed after Mars is thought to have lost its water.

NWA 7034 is 2.1 billion years old, making it the first meteorite that may hail from the transitional era. Intriguingly, it has as much as 30 times more water than previous meteorites locked up in its minerals. "It opens our mind to the possibility that climate change on Mars was more gradual," Agee says. "Maybe it didn't lose its water early on."

Hot deal

The 319.8-gram rock found its way to Agee's lab via an amateur collector named Jay Piatek. He bought it for what turned out to be a knock-down price from a Moroccan meteorite dealer, who recognised its scorched exterior as a sign that it fell from space. "It didn't look like a Martian meteorite, so it didn't have the Martian meteorite value at the time," Agee says, adding that Mars rock can go for $500 to $1000 per gram.

Piatek brought the rock to Agee's lab to find out what it was. "Honestly, I had never seen anything like it. I was baffled, initially," Agee says. "Now, about a year and a half after the first time I set eyes on this thing, we are convinced that it is Martian, a new type, and has important implications for understanding the history of Mars."

Humayun says the results so far are exciting, and that the rock's carbon content could also yield valuable insights once other researchers get their hands on it.

"What's the most exciting thing you would want to do with a rock that comes from the near surface of Mars, especially one that seems to be loaded with water?" he asks. "I would say, what about life?" Agee and colleagues found organic matter in the meteorite, he says, but it will take more work to determine whether it was of Martian or terrestrial origin.

If it's Martian, "that would spark a lot of excitement", he says.

Olympics 100m bottle-thrower 'wanted Bolt to lose'

LONDON: A man screamed abuse at Usain Bolt before throwing a plastic beer bottle on to the track shortly before the men's 100 metres final at the London Olympics, prosecutors said at his trial on Thursday.

Ashley Gill-Webb, 34, pushed his way to the front of an exclusive seating area without a ticket and shouted things like: "Usain, I want you to lose," Stratford Magistrates' Court in east London was told.

As the sprinters went up into the 'set' position on their starting blocks for the race on August 5, Gill-Webb threw the green Heineken bottle on to the track behind the athletes, prosecutors said.

Bolt went on to win the race in 9.63sec to retain his 100m title.

Gill-Webb, from South Milford, near Leeds in northern England, denies two charges of using threatening words or behaviour with intent to cause harassment.

He was confronted by Dutch judoka Edith Bosch then restrained by Olympic volunteers and arrested by police at the Olympic Stadium in east London, the court was told.

After the beer bottle was thrown, Bosch said she had confronted him saying "Dude, are you crazy?"

The judoka, who won a bronze medal at the Games, said in a statement read out in court that she had been "flabbergasted" because what Gill-Webb had done was "so disrespectful".

The court heard that Gill-Webb had suffered manic episodes in 1997 and 1999 and claimed he did not remember throwing the bottle. He was treated at a psychiatric hospital following his arrest.

Prosecutors said his DNA had been found on the bottle and that CCTV showed him throwing it "in a lobbing motion".

Opening the case, prosecutor Neil King said: "In the stadium, along with the many thousands who should have been there legitimately and were watching the race in hushed anticipation, was also Mr Gill-Webb who it is now accepted was unwell at the time.

"His conduct at the time however, the Crown (Prosecution Service) say, was one that was causing harassment, alarm and distress to those around him and his conduct was one that he intended to cause harassment, alarm and distress.

"He had somehow, without a ticket ever being found on him, made his way into very exclusive seats indeed.

"He was mingling with members of the Dutch Olympic team. Indeed he would be within striking distance of a bronze medallist Ms Edith Bosch.

"Whilst there he hurled abuse towards the athletes in the final, particularly towards the eventual winner Usain Bolt."

"This bottle landed extremely close to the athletes and it's probably luck rather than Mr Gill-Webb's judgment that it did not do anything far more serious."

Gill-Webb was granted bail providing that he stays at his home address or at hospital. The case was adjourned until January 11.

Could Mars voyage cause Alzheimer's in astronauts?

Robots may still be our best bet for Mars missions.

My brother has told me that if a manned Mars mission were seeking volunteers, he'd be the first in line, even if it meant never coming back. I wouldn't want him to go, but my desire to keep him Earth-bound is even more intense after checking out a new study on the impact of radiation on potential manned Mars missions.

A study published in PLOS One looks at the effects of galactic cosmic radiation on mice. Researchers exposed the mice to particle irradiation like that found in space. The result was cognitive impairment in line with the symptoms of Alzheimer's disease.

The study's lead author is Dr. M. Kerry O'Banion, a professor of neurobiology and anatomy at the University of Rochester Medical Center. Researchers exposed 29 male mice and 20 female mice to controlled doses of radiation at NASA's Space Radiation Laboratory at Brookhaven National Laboratory.

The mice were monitored for the next 3.5 months for the females and 6 months for the males. During this time, they underwent behavioral and memory testing, which showed a decrease in the mice's cognitive abilities.

"The doses used in this study are comparable to those astronauts will see on a mission to Mars, raising concerns about a heightened chance of debilitating dementia occurring long after the mission is over," the study states.

We may be a far cry away from sending people to Mars, but this study adds one more potential wrinkle to the many challenges ahead. It also lends some credence to those sci-fi stories about people going crazy in space. It could even explain why "Prometheus" was such a trainwreck. It wasn't the script, it was the space dementia.

Pictures We Love: Best of December

Photograph by Paula Bronstein, Getty Images

Elephants are likely one of the last things jittery coffee junkies think about while waiting for their latest shot of caffeine.

But these ponderous pachyderms are essential in the production of the latest brew from Black Ivory Coffee, a Thai company. The elephants, pictured above going for an early morning bath in northern Thailand on December 10, ingest Thai arabica coffee beans, digest them, and then expel them.

Workers pluck the processed beans from the elephant dung, wash them, and then roast them. Each serving costs about $50.

Asian elephants aren't the only animals involved in this type of 'refining' process. Asian palm civets are perhaps the most famous example of an animal whose digestive tract mellows the bitterness found in coffee beans.

Why We Love It

"The repetition of the elephants make this idyllic scene fascinating."—Amina El Banayosy, photo intern

"This picture is like a daydream, temporarily transplanting me somewhere far from the chaos and noise of city life. The pop of color in the first rider's red shirt, the sun pouring through dark clouds, and the ripples of water forming from the wading elephant are all nice details in this serene frame."—Ben Fitch, associate photo editor

Senate Panel Probes Bin Laden Movie Torture Scenes

The Senate Intelligence Committee has launched a new probe to determine how much the CIA may have influenced the portrayal of torture scenes shown in "Zero Dark Thirty," the Hollywood dramatization of the decade-long hunt for Osama bin Laden.

The probe, as first reported by Reuters and confirmed to ABC News by a spokesperson for the committee's chairman, will attempt to answer two questions: Did the CIA give filmmakers "inappropriate" access to secret material and was the CIA responsible for the perceived suggestion that harsh interrogation techniques aided the hunt for America's most wanted man?

In a press release today, Senate Intelligence Committee Chairman Sen. Dianne Feinstein's office said Feinstein, Senate Armed Services Committee Chairman Carl Levin (D.-Mich.) and former Presidential candidate John McCain (R.-Ariz.) – the latter of two are ex officio members of the Intelligence Committee – sent two letters to acting CIA Director Michael Morell in December asking just what the CIA might have told the filmmakers about the effectiveness of enhanced interrogation.

The first letter, dated Dec. 19, focused on the possibility that the CIA "misled" the filmmakers into showing torture as an effective tactic.

"As you know, the film depicts CIA officers repeatedly torturing detainees. The film then credits CIA detainees subjected to coercive interrogation techniques as providing critical lead information on the courier that led to the [bin Laden] compound," the letter says. "The CIA cannot be held accountable for how the Agency and its activities are portrayed in film, but we are nonetheless concerned, given the CIA's cooperation with the filmmakers and the narrative's consistency with past public misstatements by former senior CIA officials, that the filmmakers could have been misled by information they were provided by the CIA."

Two days after the letter was sent, Morell posted a statement on the CIA website explaining that the movie was "not a realistic portrayal of the facts" but said some information did come from detainees subjected to enhanced interrogation.

"...[T]he film creates the strong impression that the enhanced interrogation techniques that were part of our former detention and interrogation program were key to finding Bin Laden. That impression is false," Morell said. "As we have said before, the truth is that multiple streams of intelligence led CIA analysts to conclude that Bin Laden was hiding in Abbottabad. Some came from detainees subjected to enhanced techniques, but there were many other sources as well. And, importantly, whether enhanced interrogation techniques were the only timely and effective way to obtain information from those detainees, as the film suggests, is a matter of debate that cannot and never will be definitively resolved."

The trio of Feinstein, Levin and McCain wrote the second letter on New Year's Eve in apparent frustration with that statement and asked Morell to provide information on what exactly the CIA learned from detainees who underwent harsh interrogation – and if it was learned before, during or after the detainees' ordeals.

A CIA spokesperson told ABC News today the agency had received the letters and "take[s] very seriously our responsibility to keep our oversight committees informed and value[s] our relationship with Congress."

Pentagon welcomes fiscal deal, warns against cuts

WASHINGTON: US Defense Secretary Leon Panetta on Wednesday welcomed a deal to avert automatic budget cuts that would have slashed military spending and caused "damaging" consequences.

But the Pentagon chief urged more decisive action from Congress to remove the threat of mandatory cuts to defence spending that could be triggered in two months if lawmakers fail to break a stalemate over how to reduce the federal budget deficit.

"Had Congress not acted, the Department of Defense -- along with other federal agencies -- would have been forced to begin taking dramatic steps that would have severely impacted our civilian personnel and disrupted our mission," Panetta said in a statement.

He said he had warned for more than a year of the potentially disastrous impact if the automatic budget cuts, or sequestration, had gone ahead.

"Over the past few weeks, as we were forced to begin preparing to implement this law, my concerns about its damaging effects have only grown," he said.

Until the last-minute agreement was approved on Tuesday, Panetta said he was poised to notify the Pentagon's 800,000 civilian employees of possible rolling furloughs to absorb the budget cuts.

"Congress has prevented the worst possible outcome by delaying sequestration for two months. Unfortunately, the cloud of sequestration remains.

"The responsibility now is to eliminate it as a threat by enacting balanced deficit reduction," he said.

The Defense Department was already "doing its part" by cutting back planned spending by US$487 billion over the next ten years but the "spectre" of automatic cuts of another US$500 billion over the next decade had made it difficult to make budget plans, he said.

"We need to have stability in our future budgets."

Congress voted overnight on a stop-gap agreement that avoided across-the-board tax hikes and automatic spending cuts that had threatened to drive America back into recession.

The agreement, a political victory for President Barack Obama's White House, raised taxes on the very rich and delayed the threat of US$109 billion in automatic spending cuts for two months.

If the mandatory cuts were to enter into force, the Pentagon would be forced to scale back training for troops, slash spending for spy agencies, cancel purchases of some weapons and issue furloughs to large numbers of its vast civilian workforce, officials said.

The defence cuts amount to at least US$52.3 billion for 2013 -- or about 10 per cent across all the armed services -- under mandatory budget reductions, which were designed to be so drastic that Congress would reach a compromise to avoid heading over the "fiscal cliff."

If the automatic cuts go into effect in two months' time, the impact would be even more dramatic as a larger portion of the defence budget for fiscal year 2013 would be spent by then, officials said.

Some sceptics say the Pentagon and the defence industry have overstated the impact of the mandatory budget cuts, and that America's massive military spending needs to be trimmed back.

Instagram one month later: No hint of lingering troubles

New information from Web analytics firm Experian Hitwise suggests Instagram has recovered nicely from a seemingly disastrous privacy policy uproar last month.

For the 15 days since December 18, Instagram.com received more than 41.7 million total U.S. visits, an increase of 18 percent compared with the 15 days prior to the controversial proposed policy changes. The data was provided to CNET by Experian Marketing Services on request.

"The holidays see a spike in traffic as people are sharing more pictures than perhaps normal," Experian Marketing Services spokesman Matt Tatham told CNET, adding that the data doesn't include mobile traffic.

Facebook declined to provide official data or comment on this story.

Instagram members were alarmed in mid December when the Facebook-owned property announced it would include new language in its terms of service. The ambiguous language additions led many to believe that Instagram would be allowed to sell members' photos without their permission and without payment. The proposed changes set off a ruckus so loud that many users, influential celebrities included, said they'd be deleting their accounts.

Instagram co-founder Kevin Systrom responded by assuring members that their photos would not be sold, and he apologized for the confusion. The offending language has since been removed -- with Instagram reverting to its 2010 terms of service just before the holiday season kicked in -- but the damage was done, according to a widely circulated New York Post article claiming an Instagram exodus was in effect. That story cited third-party data from AppData -- which tracks Instagram users who log on through Facebook -- that showed a decline of close to 25 percent of the app's daily active users. An Instagram representative told CNET that the data was inaccurate.

If Instagram's Web traffic is any indicator, the photo-sharing app is weathering its privacy storm quite nicely, likely with the holidays to thank for its buoyancy. The 18 percent uptick in Web traffic is not reflective of user growth or indicative of any changes on mobile; it may represent nothing more than normal holiday fluctuations in sharing behaviors. Still, the 41.7 million visits Instagram accrued during the past 15 days speak to the continued relevance and growing footprint of a service that many turn to for sharing their most intimate moments.
