Hollies Get Prickly for a Reason



With shiny evergreen leaves and bright red berries, holly trees are a naturally festive decoration seen throughout the Christmas season.


They're famously sharp. But not all holly leaves are prickly, even on the same tree. And scientists now think they know how the plants are able to make sharper leaves, seemingly at will. (Watch a video about how Christmas trees are made.)


A new study published in the Botanical Journal of the Linnean Society suggests leaf variations on a single tree are the combined result of animals browsing on them and the trees' swift molecular response to that sort of environmental pressure.


Carlos Herrera of the National Research Council of Spain led the study in southeastern Spain. He and his team investigated the European holly tree, Ilex aquifolium. Hollies, like other plants, can make different types of leaves at the same time. This is called heterophylly. Out of the 40 holly trees they studied, 39 trees displayed different kinds of leaves, both prickly and smooth.

Some trees looked like they had been browsed upon by wild goats and deer. On those trees, the lower 8 feet (2.5 meters) had more prickly leaves, while higher up the leaves tended to be smooth. Scientists wanted to figure out how the holly trees could make the change in leaf shape so quickly.


All of the leaves on a tree are genetic twins and share exactly the same DNA sequence. By looking in the DNA for traces of a chemical process called methylation, which modifies DNA but doesn't alter the organism's genetic sequence, the team could determine whether leaf variation was a response to environmental or genetic changes. They found a relationship between recent browsing by animals, the growth of prickly leaves, and methylation.


"In holly, what we found is that the DNA of prickly leaves was significantly less methylated than prickless leaves, and from this we inferred that methylation changes are ultimately responsible for leaf shape changes," Herrera said. "The novelty of our study is that we show that these well-known changes in leaf type are associated with differences in DNA methylation patterns, that is, epigenetic changes that do not depend on variation in the sequence of DNA."


"Heterophylly is an obvious feature of a well-known species, and this has been ascribed to browsing. However, until now, no one has been able to come up with a mechanism for how this occurs," said Mike Fay, chief editor of the Botanical Journal of the Linnean Society and head of genetics at the Kew Royal Botanic Gardens. "With this new study, we are now one major step forward towards understanding how."


Epigenetic changes take place independently of variation in the genetic DNA sequence. (Read more about epigenetics in National Geographic magazine's "A Thing or Two About Twins.")


"This has clear and important implications for plant conservation," Herrera said. In natural populations that have their genetic variation depleted by habitat loss, the ability to respond quickly, without waiting for slower DNA changes, could help organisms survive accelerated environmental change. The plants' adaptability, he says, is an "optimistic note" amidst so many conservation concerns. (Related: "Wild Holly, Mistletoe, Spread With Warmer Winters.")

Obama, Boehner Not Far Apart on 'Cliff'? Not Really

There are some in Washington and around Capitol Hill who keep saying that House Speaker John Boehner and President Obama really aren’t that far apart on the “fiscal cliff” and there will be a deal despite Boehner’s proposal to hold a vote on his “Plan B.”


Let’s deconstruct the two parts of that thinking.


Boehner and Obama really aren’t that far apart?


Not really.


The differences are more significant than just tax rates.  Republicans say the Democratic offer is really $800 billion in spending cuts and $1.3 trillion in tax increases.  That is because the inflation adjustment applies to tax rates* as well as Social Security — resulting in less than $100 billion in added tax revenues.


Democrats count that as a spending cut.  Republicans say that is a tax hike.  So the real difference, from their perspective, is $450 billion.  The $400,000 vs. $1 million threshold for tax rates hikes is just one part of this.  Republicans want more spending cuts and fewer tax increases.

Obama and Senate Democrats are fond of saying they are this close (fingers close together).  They say Boehner should just accept the president’s offer.


But, as I asked Senate Majority Leader Harry Reid, D-Nev., earlier today: If you are this close why not just accept Boehner’s offer?  He dodged, saying that Boehner’s offer wasn’t really an offer and likened him to Lucy and the football — you’ll recall the routine in which the “Peanuts” character would pull away the ball at the last second and leave Charlie Brown kicking at nothing but air.


Both sides like to talk about Lucy and the football, but that is another story.  Will there be a deal?


They should be able to do a deal.  I know where the deal should be.  So do you.  But, really, they aren’t quite as close as the nifty charts like this one from the Washington Post suggest. And this is about much more than the $400,000 tax-rate threshold.


*By lowering the government’s calculation for inflation, the income level for the top rates would rise at a slower rate, putting more and more people into the top rates.

Megaupload New Zealand extradition case delayed again






WELLINGTON: A US bid to extradite Megaupload boss Kim Dotcom from New Zealand for alleged online piracy has been delayed for a second time and will not be heard until August next year, his lawyers said on Thursday.

The extradition case, launched after Dotcom's arrest in January for alleged online piracy, was originally due to go to court in August, then pushed back to March next year amid legal wrangling over evidence disclosure.

A spokeswoman for Dotcom's Auckland-based barrister Paul Davison said the court had rescheduled the hearing again to August 2013. She did not provide a reason for the change.

Police are investigating New Zealand's foreign intelligence agency, the Government Communications Security Bureau (GCSB), for illegally spying on Dotcom ahead of his arrest in a raid on his Auckland mansion in January.

Prime Minister John Key earlier this year issued a public apology to Dotcom, acknowledging the German national should have been off-limits to the agency because he holds New Zealand residency.

It was the latest in a string of setbacks for the case against Dotcom, who remains free on bail in New Zealand, including a court ruling that the search warrants used in the raid on his mansion were illegal.

The 38-year-old's Megaupload file-sharing empire, which at its peak had 50 million daily visitors and accounted for four percent of all Internet traffic, was shut down after the raid and Dotcom has indicated he will seek damages.

Dotcom denies US allegations the Megaupload sites netted more than $175 million in criminal proceeds and cost copyright owners more than $500 million by offering pirated copies of movies, TV shows and other content.

The US Justice Department and FBI want Dotcom to face charges of racketeering fraud, money laundering and copyright theft in a US court, which could see him jailed for up to 20 years if convicted.

Sonia's lunge helps Congress grab promotion quota bill

NEW DELHI: Sonia Gandhi restored the Congress stamp on 'promotion quota' bill just when BSP chief Mayawati had all but cornered the glory, as she took centrestage in the drama triggered by Samajwadi Party to stall the quota bill in Lok Sabha.

SP MP Yashbir Singh snatched the papers from personnel minister V Narayanasamy's hands when the government decided to initiate the discussion in the din. The "deplorable" act triggered a bout of push and shove that brought Congress and protesting SP MPs to blows.

But it was Sonia's desperate lunge at the delinquent Samajwadi MP that dominated the proceedings. Sonia, who sits at the edge of the well in the front row, in a reflex action, went for Singh's arm to retrieve the paper, in the process being caught in the melee caused by sloganeering Samajwadis. Congress MPs told TOI that the party president also seemed annoyed with Narayansamy for not keeping a second copy of the Bill.

The scene brought Congress MPs to the well, with many MPs asking her to come back but in vain. While it all happened in a jiffy, Vilasrao Muttemwar pursued Singh in a rage. It invited vocal allegations that he had punched the Samajwadi Party MP, himself a dalit from the reserved Nagina constituency. Muttemwar denied the charge while adding that he had merely gone to protect his boss. "It is my duty," he told TOI.

The melee postponed the bill for the day as a stunned Speaker Meira Kumar adjourned the proceedings, pushing the drama to the last day of the session. Parliamentary affairs minister Kamal Nath told reporters the incident was condemnable and asserted the government would take up the bill again on Thursday.

Samajwadi chief Mulayam Singh Yadav backed his rampaging contingent and played down the outrage over snatching of papers by saying it was "not the first time such a scene had happened".

Inaction on part of Sonia and her troops on Wednesday would have marked a blow for Congress that has already come across as a reluctant player who has been forced to follow Mayawati's lead on the promotion quota bill.

Failure to clinch the bill in the Lok Sabha on Thursday- a very strong possibility, considering the reluctance of the BJP to commit its support- will again make it vulnerable to attacks from the BSP chief. Sonia's reflexes may have saved the day for Congress on Wednesday, underlining her cruciality for the party at a time when political parlours remain abuzz with speculation about the elevation of son Rahul. It also helped Congress differentiate itself from the BJP which on Wednesday appeared wracked by upper caste resentment in its ranks against the "promotion quota".

Her presence in the Lok Sabha when the bill was taken up in the post-lunch session after two adjournments forced by the protesting Samajwadis did indicate seriousness. But it was her act of taking on the hostile SP member with screams of "give it back" that underlined the eagerness of the leadership to pass the legislation crafted to restore reservation in promotions for SCs and STs.

Sonia's political smarts may mitigate the loss in the war of credits at the hands of the volatile BSP supremo who put her indelible stamp on 'promotion quota' by taking it up in the monsoon session and then pursuing it right to the end of the winter session.

In fact, the government had appeared happy to hide behind Samajwadi protests to consign the legislation to the deep freeze, until Mayawati's stunning allegation that Rajya Sabha chairman Hamid Ansari and the Centre were complicit in the disorder designed to derail the legislation led to its dramatic passage in the upper House. The success of the bill was roundly attributed to her commitment.

The scene appeared changed after Wednesday's drama as Congress surfaced with a triumphant spin to Sonia's march into the well. Personnel minister Narayanasamy said, "It shows the importance she gives to this bill."

In the Congress vs SP faceoff, BJP appeared squeezed out of the action, this time appearing to be hiding behind the Samajwadis. The saffron outfit has been in the throes of a mutiny of sorts, with upper caste members questioning the backing for quota on the ground that it would put off the party's core constituency.

While the BJP is unlikely to revise support for the bill that can have consequences for its pull among dalits and tribals, the party's silence during the drama and the active engagement of senior leaders with Samajwadis crying manhandling, projected it as indifferent, if not hostile.

Detecting Rabid Bats Before They Bite


A picture is worth a thousand words—or in the case of bats, a rabies diagnosis. A new study reveals that rabid bats have cooler faces compared to uninfected colony-mates. And researchers are hopeful that thermal scans of bat faces could improve rabies surveillance in wild colonies, preventing outbreaks that introduce infections into other animals—including humans.

Bats are a major reservoir for the rabies virus, according to the Centers for Disease Control and Prevention (CDC) in Atlanta. Previous research shows that bats can transmit their strains to other animals, potentially putting people at risk. (Popular Videos: Bats share the screen with creepy co-stars.)

Rabies, typically transmitted in saliva, targets the brain and is almost always fatal in animals and people if left untreated. No current tests detect rabies in live animals—only brain tissue analysis is accurate.

Searching for a way to detect the virus in bats before the animals died, rabies specialist James Ellison and his colleagues at the CDC turned to a captive colony of big brown bats (Eptesicus fuscus). Previous studies had found temperature increases in the noses of rabid raccoons, so the team expected to see similar results with bats.

Researchers established normal temperature ranges for E. fuscus—the bat species most commonly sent for rabies testing—then injected 24 individuals with the virus. The 21-day study monitored facial temperatures with infrared cameras, and 13 of the 21 bats that developed rabies showed temperature drops of more than 4ÂșC.

"I was surprised to find the bats' faces were cooler because rabies causes inflammation—and that creates heat," said Ellison. "No one has done this before with bats," he added, and so researchers aren't sure what's causing the temperature changes they've discovered in the mammals. (Related: "Bats Have Superfast Muscles—A Mammal First.")

Although thermal scans didn't catch every instance of rabies in the colony, this method may be a way to detect the virus in bats before symptoms appear. The team plans to fine-tune their measurements of facial temperatures, and then Ellison hopes to try surveillance in the field.

This study was published online November 9 in Zoonoses and Public Health.

Scammers Could Profit Off Sandy Hook Tragedy













Scammers may be looking to cash in on the public's generosity following the Sandy Hook massacre, the Better Business Bureau warned.


"It is a challenge to be on guard because public sympathy and emotions are running high," said Bennett Weiner, chief operating officer of the BBB Wise Giving Alliance, a group that helps charitable donors make informed decisions.


Weiner said it's difficult for scams to be detected in the first week following every national tragedy, however he suspects unscrupulous people are already out there, eager to cash in on the massacre.


How to Help Newtown Families


False websites or phone calls soliciting help for the victims' families are two of the easiest and most common scams Weiner said he sees.


"They're hard to identify because people don't know they've been taken and they're not going to know until down the road," he said.

After the Sandy Hook massacre, countless Facebook pages for the victims, listings on crowdfunding sites and community drives have been established to solicit donations.


Timeline: Tragedy At Sandy Hook


While many of them may be legitimate, Weiner warns people to do their research.


"You really have to be watching out for newly created things. There may be some well-intended effort, but you have no way to look at their track record," he said. "I can tell you from experience there are some cautions associated with it."


Any fundraising effort that makes vague statements, such as "we're going to help the victims and families," is another red flag to watch out for, Weiner said.


Whether it's fundraising for the Aurora theater victims or a local terminally ill child, Weiner said the BBB sees these kinds of scams "time and time again" and actively investigates them.


"It is a challenge to be on guard after a tragedy," he said. "But you shouldn't give to any organization without checking them out first."

Euro continues push against dollar






NEW YORK: The euro pushed higher against the dollar Tuesday, helped by improvements in Greece's financial status and a Spanish debt sale, and as Washington continued to battle over the looming fiscal cliff.

Meanwhile the yen slipped to its lowest level since April 2011 as Japan's incoming prime minister pressed the central bank for more stimulus.

The euro reached its best level since the beginning of May, ending at $1.3225 at 2300 GMT, up from $1.3161 late Monday.

The seven-month high for the euro came "on the back of successful sales of Greek and Spanish bills," said Benjamin Spier of Daily FX.

"Spain sold 3-month and 6-month bills for 3.52 billion euros, better than the maximum target of 3.5 billion euros. Greece sold 13-week treasury bills for 1.3 billion euros at a 4.11 percent yield," he said.

Shortly afterward, Greece's credit rating was upgraded by Standard & Poor's from "selective default" to B-, with a stable outlook, following Athens' debt buyback that earned it fiscal breathing space and new bailout funds releases from the eurozone.

The upgrade "reflects our view of the strong determination of European Economic and Monetary Union (eurozone) member states to preserve Greek membership in the eurozone," S&P said.

Meanwhile, the dollar got no help from Washington politicians, who have not yet reached a deal on a long-term deficit reduction plan that would also help the country avoid crunching tax hikes and spending cuts slated for January 1.

The yen continued to fall, setting 20-month lows against the dollar and euro, two days after the Liberal Democratic Party swept to a general election victory that is returning Shinzo Abe to the premiership.

Abe met with Bank of Japan governor Masaaki Shirakawa at his party's headquarters Tuesday and told the central banker he wanted to set a two percent inflation target, in the opening salvo of his battle to kickstart the economy.

"I told him I want to reach a policy accord with the BoJ for the two percent inflation target that I promoted throughout the election campaign," Abe told reporters.

The dollar rose to 84.28 yen from 83.87 yen Monday, while the euro hit 111.47 yen from 110.40

In other currencies, the dollar slipped to 0.9134 Swiss francs, while the pound gained to $1.6247.

India lost $123bn in black money in 10 yrs: US think tank report

BEIJING: China is listed as the leading source of global outflows of tainted money with India ranking eighth in the list compiled by a Washington-based think tank, Global Financial Integrity. China lost $2.74 trillion and India $123 billion to international outflows of illicit cash between 2001 and 2010, it said.

Some 150 developing countries lost $5.9 trillion by way of illegal outflows in those 10 years, the Global Financial Integrity said in a report, which showed that the financial crisis has not adversely affected the production and flow of corrupt money.

The report, co-authored by an economist of Indian origin, Dev Kar, said the global outflows rose from $776 billion in 2009 amid the financial crisis to $859 billion in 2010. The all-time high of $871 billion was in 2008.

Malaysia with $64 billion in illegal outflows took the second position followed by Mexico. The bulk of illegal money flows accounting for 61% came from Asia. It is followed by just over 15% from the Western hemisphere and just over 10% from West Asia-Gulf and North Africa.

Illegal money out of China was $420 billion in 2010 and exceeded $2.7 trillion for the decade ending in 2010, which was nearly half that period's total for all developing countries.
