I suppose that in moving from Mexico City to Paris, and feeling a sudden burst of elation for not having to worry so intently about drug and gang violence and, worst of all kidnapping, I went to the extreme.

A man knocked on the door of our temporary apartment saying he needed to check on something and asked if he could come in. He must have said what he was checking but my French, only now on its way back after lying dormant for over two decades, missed the details. He was dressed in work clothes, and I let him in.

He first said he was looking for the heater panel, then started asking all kinds of questions about who we were and how long we?d been in France. I thought this was a bit bizarre, but didn't think much of it.

Then he spotted the chimney. He opened the screen: ?Oh no, look at all of this soot.? (I had to look up the word for soot, suie, on my laptop.)

?You have a small child,? he went on. ?If she breathes this in, it could be the end. I am obligated to fix this.?

In my daze of jetlag, living out of suitcases, with a mountain of bureaucracy to tackle each day, I actually thought this man might be from the city government, and he was doing his municipal duty, for free, to make sure no Paris residents ? even foreigners, God bless France! ? breathe contaminated air.

I almost let him get to work ? until my more rational husband said, ?Let?s call the owner first.?

The owner's response was immediate: ?Get that guy out of the house now.?

I learned later that it?s a well-known scam in Paris that plumbers or electricians and other workers will come in, and tell you you need X, Y, and Z fixed. A colleague told me one man entered her house, broke a pipe, and then tried to get them to pay to fix it. I told the guardian downstairs about our visitor, and she said any communal or municipal work to be done will always be posted in the building.

Some of these scams are actually done by thieves, she said, who might rob you ? or worse. ?Don?t let anyone in your house. It could be very dangerous.?

I did learn back in elementary school not to talk to strangers, and most definitely not to let them through the front door.

But I had a momentary lapse of judgment, a good reminder that you have to be careful anywhere ? even in Paris!

Keeping stem cells strong: RNA molecule protects stem cells during inflammation

May 21, 2013 ? When infections occur in the body, stem cells in the blood often jump into action by multiplying and differentiating into mature immune cells that can fight off illness. But repeated infections and inflammation can deplete these cell populations, potentially leading to the development of serious blood conditions such as cancer. Now, a team of researchers led by biologists at the California Institute of Technology (Caltech) has found that, in mouse models, the molecule microRNA-146a (miR-146a) acts as a critical regulator and protector of blood-forming stem cells (called hematopoietic stem cells, or HSCs) during chronic inflammation, suggesting that a deficiency of miR-146a may be one important cause of blood cancers and bone marrow failure.

The team came to this conclusion by developing a mouse model that lacks miR-146a. RNA is a polymer structured like DNA, the chemical that makes up our genes. MicroRNAs, as the name implies, are a class of very short RNAs that can interfere with or regulate the activities of particular genes. When subjected to a state of chronic inflammation, mice lacking miR-146a showed a decline in the overall number and quality of their HSCs; normal mice producing the molecule, in contrast, were better able to maintain their levels of HSCs despite long-term inflammation. The researchers' findings are outlined in the May 21 issue of the new journal eLIFE.

"This mouse with genetic deletion of miR-146a is a wonderful model with which to understand chronic-inflammation-driven tumor formation and hematopoietic stem cell biology during chronic inflammation," says Jimmy Zhao, the lead author of the study and a MD/PhD student in the Caltech laboratory of David Baltimore, the Robert Andrews Millikan Professor of Biology. "It was surprising that a single microRNA plays such a crucial role. Deleting it produced a profound and dramatic pathology, which clearly highlights the critical and indispensable function of miR-146a in guarding the quality and longevity of HSCs."

The study findings provide, for the first time, a detailed molecular connection between chronic inflammation, and bone marrow failure and diseases of the blood. These findings could lead to the discovery and development of anti-inflammatory molecules that could be used as therapeutics for blood diseases. In fact, the researchers believe that miR-146a itself may ultimately become a very effective anti-inflammatory molecule, once RNA molecules or mimetics can be delivered more efficiently to the cells of interest.

The new mouse model, Zhao says, also mimics important aspects of human myelodysplastic syndrome (MDS) -- a form of pre-leukemia that often causes severe anemia, can require frequent blood transfusions, and usually leads to acute myeloid leukemia. Further study of the model could lead to a better understanding of the condition and therefore potential new treatments for MDS.

"This study speaks to the importance of keeping chronic inflammation in check and provides a good rationale for broad use of safer and more effective anti-inflammatory molecules," says Baltimore, who is a coauthor of the study. "If we can understand what cell types and proteins are critically important in chronic-inflammation-driven tumor formation and stem cell exhaustion, we can potentially design better and safer drugs to intervene."

Funding for the research outlined in the eLIFE paper, titled "MicroRNA-146a acts as a guardian of the quality and longevity of hematopoietic stem cells in mice," was provided by the National Institute of Allergy and Infectious Disease; the National Heart, Lung, and Blood Institute; and the National Cancer Institute. Yvette Garcia-Flores, the lead technician in Baltimore's lab, also contributed to the study along with Dinesh Rao from UCLA and Ryan O'Connell from the University of Utah. eLIFE, a new open-access, high-impact journal, is backed by three of the world's leading funding agencies, the Howard Hughes Medical Institute, the Max Planck Society, and the Wellcome Trust.

Wall Street watchdog to review broker bonus disclosure plan in July

By Suzanne Barlyn

WASHINGTON (Reuters) - Wall Street's watchdog will present a plan to its board in July that would require brokers to tell certain clients about compensation they receive when they switch firms, the regulator's chief said on Tuesday.

Richard Ketchum, the Financial Industry Regulatory Authority's chairman and chief executive, said he and his staff will review numerous letters about the proposal from industry and investor advocacy groups before the July meeting. Ketchum made the remarks during a briefing for reporters at FINRA's annual conference in Washington.

FINRA's plan spotlights the lucrative signing packages, offered to top advisers, that have scaled new highs over the past year. While the largest brokerage firms support the proposal, it has been controversial because others are concerned that customers will misjudge the disclosures and that it would ultimately limit compensation.

Disclosing a lucrative bonus would inform investors of a conflict of interest their brokers may have when they ask clients to switch firms along with them. Such a move could be costly to investors, who may have to sell certain securities, such as brokerage branded-mutual funds, that are not available through their broker's new firm, Ketchum has said.

Numerous letters to FINRA about the proposal from the securities industry and investor advocacy groups "make some fair points," Ketchum told reporters.

He said another proposal, requiring that brokerage websites link to the regulator's "BrokerCheck" background disclosure database -- which includes disciplinary violations as well as licensing information and work history -- may not be ready in time for the board's July meeting.

FINRA, Wall Street's industry-funded regulator, must seek permission from its board of governors for sending rule proposals to the U.S. Securities and Exchange Commission for review and final approval.

A final compensation disclosure rule, however, could be a long way off even if FINRA's board approves it. "There are a lot of steps between now and when any rule would be in place," Ketchum told reporters.

The regulator withdrew the BrokerCheck database plan from SEC consideration in April after brokerage firms raised questions about how they would apply such a requirement in other online contexts, such as social media sites.

The regulator is also enhancing its regulatory processes to help boost investor confidence in U.S. financial markets, Ketchum said in his prepared remarks to Wall Street professionals. Those efforts include evaluating precautions brokerages are taking to manage certain risks.

A pilot program for FINRA brokerage examinations, launched last October, aims to identify potential risks by requiring brokerages to upload a broad array of data for FINRA to review before examiners visit on-site, Ketchum said.

The new approach gives examiners more flexibility to raise questions about red flags, Ketchum said. FINRA will phase in the program for all brokerages toward the end of 2013, he said.

Bed sharing leads to fivefold increase in risk of crib death for babies whose parents do not smoke

May 20, 2013 ? Parents who share a bed with their breastfed baby could face a fivefold increase in the risk of crib death, even if the parents do not smoke, according to a new study. The research was led by the London School of Hygiene & Tropical Medicine and is published in BMJ Open.

Crib death -- also known as cot death or sudden infant death syndrome (SIDs) -- remains a major cause of death among babies under 1 year of age in high income countries. There is already a general consensus that sleeping with a baby increases the risk of cot death if the parents smoke or if the mother has been drinking alcohol or taking drugs. However, there are conflicting opinions as to whether bed sharing in general represents a risk when these factors are not present.

Some countries, including the US and the Netherlands, advise all parents against sharing a bed with their baby for the first 3 months. The UK currently only advises certain groups, including parents who are smokers, not to bed share.

The new study is the largest ever analysis of its kind. Researchers examined the individual records of 1,472 cot death cases and 4,679 control cases across five major studies. They found that the risk of cot death among breastfed babies under 3 months increased with bed sharing, even when the parents did not smoke and the mother had not consumed alcohol or drugs. This fivefold increase was in comparison to room sharing, where a baby slept in a cot in the parents' room.

The researchers estimate that 81% of cot deaths among babies under 3 months with no other risk factors could be prevented if they did not sleep in the same bed as their parents. The study also showed that the risk associated with bed sharing decreases as a baby gets older, and that the peak period for instances of cot death was between 7 and 10 weeks.

Professor Bob Carpenter from the London School of Hygiene & Tropical Medicine who was lead author on the study said: "Currently in the UK more than half of cot deaths occur while a baby is sleeping in the same bed as its parents. Although it is clear that smoking and drinking greatly increase the risk of cot death while bed sharing, our study shows that there is in fact an increased risk for all babies under 3 months who bed share, even if their parents do not smoke or drink.

"If parents were made aware of the risks of sleeping with their baby, and room sharing was instead promoted in the same way that the 'Back to Sleep' campaign was promoted 20 years ago to advise parents to place their newborn infants to sleep on their backs, we could achieve a substantial reduction in cot death rates in the UK. Annually there are around 300 cot death cases in babies under a year old in the UK, and this advice could save the lives of up to 40% of those. Health professionals need to make a definite stand against all bed sharing, especially for babies under 3 months."

The authors state that babies can still be brought into the parents' bed for comfort and feeding during the night, but that they should be placed in a cot next to the parents' bed to sleep.

SKorea: NKorea fires sixth projectile into waters

SEOUL, South Korea (AP) ? North Korea fired short-range projectiles into its own eastern waters Monday for a third straight day, Seoul officials said. The North said it was bolstering deterrence against enemy attack.

North Korea regularly conducts short-range missile tests. Analysts say the recent launches appear to be weapons tests or an attempt to get U.S. and South Korean attention amid tentative signs of diplomacy after soaring tensions that followed U.N. sanctions aimed at a North Korean nuclear test in February.

The two projectiles fired by North Korea on Monday had similar trajectories as four previous launches over the past two days, according to officials at Seoul's Defense Ministry and Joint Chiefs of Staff. Officials were analyzing whether the projectiles were missiles or rockets fired from a large-caliber gun North Korea may be developing, the officials said on condition of anonymity citing department rules.

Defense Ministry spokesman Kim Min-seok told reporters earlier Monday that South Korea is taking seriously whatever weapons North Korea develops because it could attack the South. He said artillery guns with a larger caliber will likely have more destructive power.

South Korea urged North Korea to behave responsibly, while the U.S. said threats or provocations would only further deepen the North's international isolation.

North Korea's Committee for the Peaceful Reunification of Korea on Monday called South Korean and U.S. criticism an "intolerable challenge" that is deepening tension. It said it conducted "rocket launching tests" on Saturday and Sunday as part of drills to bolster deterrence against what it calls U.S. and South Korean plots to launch nuclear strikes against North Korea. It didn't comment on Monday's firing.

North Korea has a variety of missiles but Seoul and Washington don't believe the country has mastered the technology needed to make nuclear warheads small and light enough to be placed on a missile capable of reaching the U.S.

The Korean Peninsula officially remains in a state of war because the 1950-53 Korean War ended with an armistice, not a peace treaty.

Iran hangs two spies working for Israel and U.S.: report

DUBAI (Reuters) - Iranian authorities executed two men on Sunday convicted of working for Israeli and U.S. spy agencies, Iran's Fars news agency reported.

Mohammad Heidari, accused of passing security-related information and secrets to Israeli Mossad agents in exchange for money, and Kourosh Ahmadi, accused of gathering information for the U.S. Central Intelligence Agency, were hanged at dawn, it said.

The sentence for their execution was handed down by Tehran's Revolutionary Court and confirmed by the country's Supreme Court. The report did not say when the pair were arrested nor when their trial took place.

Iran has in the past said it had successfully detected and dismantled spy networks operating inside the country. It has blamed the assassinations of scientists associated with its disputed nuclear program on Western spy agencies, especially Mossad.

The United States has denied any role in the killings. Israel has not commented.

Penn engineers' nanoantennas improve infrared sensing

A team of University of Pennsylvania engineers has used a pattern of nanoantennas to develop a new way of turning infrared light into mechanical action, opening the door to more sensitive infrared cameras and more compact chemical-analysis techniques.

The research was conducted by assistant professor Ertugrul Cubukcu and postdoctoral researcher Fei Yi, along with graduate students Hai Zhu and Jason C. Reed, all of the Department of Material Science and Engineering in Penn's School of Engineering and Applied Science.

It was published in the journal Nano Letters.

Detecting light in the mid-infrared range is important for applications like night-vision cameras, but it can also be used to do spectroscopy, a technique that involves scattering light over a substance to infer its chemical composition. Existing infrared detectors use cryogenically cooled semiconductors, or thermal detectors known as microbolometers, in which changes in electrical resistance can be correlated to temperatures. These techniques have their own advantages, but both need expensive, bulky equipment to be sensitive enough for spectroscopy applications.

"We set out to make an optomechanical thermal infrared detector," Cubukcu said. "Rather than changes in resistance, our detector works by connecting mechanical motion to changes in temperature."

The advantage to this approach is that it could reduce the footprint of an infrared sensing device to something that would fit on a disposable silicon chip. The researchers fabricated such a device in their study.

At the core of the device is a nanoscale structure about a tenth of a millimeter wide and five times as long made of a layer of gold bonded to a layer of silicon nitride. The researchers chose these materials because of their different thermal expansion coefficients, a parameter that determines how much a material will expand when heated. Because metals will naturally convert some energy from infrared light into heat, researchers can connect the amount the material expands to the amount of infrared light hitting it.

"A single layer would expand laterally, but our two layers are constrained because they're attached to one another," Cubukcu said. "The only way they can expand is in the third dimension. In this case, that means bending toward the gold side, since gold has the higher thermal expansion coefficient and will expand more."

To measure this movement, the researchers used a fiber interferometer. A fiber optic cable pointed upward at this system bounces light off the underside of the silicon nitride layer, enabling the researchers to determine how far the structure has bent upwards.

"We can tell how far the bottom layer has moved based on this reflected light," Cubukcu said. "We can even see displacements that are thousands of times smaller than a hydrogen atom."

Other researchers have developed optomechanical infrared sensors based on this principle, but their sensitivities have been comparatively low. The Penn team's device is an improvement in this regard due to the inclusion of "slot" nanoantennas, cavities that are etched into the gold layer at intervals that correspond to wavelengths of mid-infrared light.

"The infrared radiation is concentrated into the slots, so you don't need any additional material to make these antennas," Cubukcu said. "We take the same exact platform and, by patterning it with these nanoscale antennas, the conversion efficiency of the detector improves 10 times."

The inclusion of nanoantennas provides the device with an additional advantage: the ability to tailor which type of light it is sensitive to by etching a different pattern of slots on the surface.

"Other techniques can only work at the maximum absorption determined by the material itself," Yi said. "Our antennas can be engineered to absorb at any wavelength."

While only a proof-of-concept at this stage, future research will demonstrate the device's capabilities as a low-cost way of analyzing individual proteins and gas molecules.

Scientists capture first direct proof of Hofstadter butterfly effect

Friday, May 17, 2013

A team of researchers from several universities ? including UCF ?has observed a rare quantum physics effect that produces a repeating butterfly-shaped energy spectrum in a magnetic field, confirming the longstanding prediction of the quantum fractal energy structure called Hofstadter's butterfly.

This discovery by the team paves the way for engineering new types of extraordinary nanoscale materials that can be used to develop smaller, lighter and faster electronics, including sensors, cell phones, tablets and laptops.

First predicted by American physicist Douglas Hofstadter in 1976, the butterfly pattern emerges when electrons are confined to a two-dimensional plane and subjected to both a periodic potential energy and a strong magnetic field. The Hofstadter butterfly is a fractal pattern?meaning that it contains shapes that repeat on smaller and smaller size scales. Fractals are common in systems such as fluid mechanics, but rare in the quantum mechanical world. The Hofstadter butterfly is one of the first quantum fractals theoretically discovered in physics but, until now, there has been no direct experimental proof of this spectrum.

Columbia University led the study and also involved scientists from the City University of New York, Tohoku University and the National Institute for Materials Science in Japan. Columbia prepared the sample and the UCF team measured the regular recurrence of the high-fidelity periodic pattern, engineered by inducing nanoscale ripples on graphene, a carbon material. The measured recurrence served as the essential proof that the measured spectrum was indeed the Hofstadter butterfly. The image that captured the evidence was taken in UCF Assistant Professor Masa Ishigami's laboratory.

Jyoti Katoch, Ishigami's graduate student, used a non-contact atomic force high-resolution microscope to image the ripples, which have the height of only 0.2 angstroms (twenty trillionth of a meter), to confirm that the observed Hofstadter butterfly spectrum indeed matched the theoretical prediction.

"The arrangement of individual atoms, even just one atom can drastically alter properties of nanoscale materials. That is the basis for nanotechnology," Ishigami said. "Atomic structures must be resolved to understand the properties of nanoscale materials. What we do here at UCF is to explain why nanoscale materials behave so different by resolving their atomic structures. Only when we understand the origin of the extraordinary properties of nanoscale materials, we can propel nanoscience and technology forward. What Jyoti has done here is to image how graphene is rippled to explain the observed Hofstadter spectrum."

UCF's laboratory utilizes a novel, the state-of-the-art microscopy technique to simultaneously determine the atomic structure and electronic properties of nanoscale materials such as graphene.

Katoch has been working with Ishigami since 2008, when Ishigami joined UCF. Katoch helped build the laboratory and developed the atomic-resolution capability critical to capturing the picture proof for this study.

Ishigami has a Ph.D. in physics from the University of California at Berkeley and a bachelor's degree in physics from the Massachusetts Institute of Technology. He has won multiple awards, including the Intelligence Community postdoctoral fellowship and the Hertz graduate fellowship, and has published more than 30 papers in journals including Science.

GOP hopes IRS scandal will snag health care law

WASHINGTON (AP) ? Political scandals have strange ways of causing collateral damage, and Republicans are hoping the furor over federal tax enforcers singling out conservative groups will ensnare their biggest target: President Barack Obama's health care law.

There is a link, but it may only be coincidence. No one appears to have connected the dots factually, and it's unclear whether they will.

The Internal Revenue Service has a major role in carrying out the health care law, because financial assistance to help the uninsured afford coverage will be funneled through the tax system. At the same time, the IRS is also responsible for penalties on individuals and employers who fail to comply with the law's requirements.

But the really tantalizing connection is that a former head of the office that subjected tea-party groups seeking tax exemptions to tougher scrutiny is now running the tax agency's division in charge of implementing the health care law.

That official apparently switched roles before internal alarm bells went off about the problem. But feed all that into today's frenzied world of online speculation, and red-meat associations are irresistible.

In Saturday's weekly GOP radio and Internet address, Maryland Rep. Andy Harris tried to make the connection.

"If we've learned anything this week, it's that the IRS needs less power, not more," Harris said. "As matter of fact, it turns out that the IRS official who oversaw the operation that's under scrutiny for targeting conservatives is now in charge of the IRS's Obamacare office. You can't make this stuff up."

Earlier in the week, debating the latest GOP bill to try to repeal the health care law, Rep. Michele Bachmann, R-Minn., also reached for a link. Citing the IRS role in administering the law, she said: "Under Obamacare, the average American will pay more, they'll get less, and now they have to worry that their government may punish them because of their beliefs."

Nonsense, says Rep. Sander Levin, D-Mich., ranking Democrat on the Ways and Means Committee, which oversees the IRS.

"There really isn't a tie," said Levin. "This is another effort by the Republicans to essentially try to score political points."

The head of the IRS health care office, Sarah Hall Ingram, was in charge of the tax exempt division when agents first started improperly targeting conservative groups over their applications for tax-exempt status. The fallout has already led to the ouster of acting IRS Commissioner Steven Miller, followed by the announcement that the current head of the division will retire.

But the IRS said Ingram was re-assigned to help the agency implement the health care law in December 2010, about six months before a Treasury inspector general's report said her subordinate, the director of exempt organizations, learned about the targeting.

"There isn't any evidence that Sarah Ingram had any inkling of the problems," said Levin. In contrast, Levin continued, ousted commissioner Miller failed to adequately inform Congress after he learned.

At a congressional hearing on the IRS scandal Friday, Miller was grilled by Rep. Pat Tiberi, R-Ohio, about Ingram's shift to running the IRS health care office.

Tiberi: "Why would you promote somebody to that position who was in charge of the exempt organization division, which certainly has had some controversy over the last couple years, under an investigation?

Miller: "Because she's a superb civil servant, sir."

Tiberi: "So she had nothing to do with this?"

Miller: "I wouldn't imagine so."

GOP lawmakers are smart to be looking for a connection, said Tom Davis, a former Republican congressman from Virginia, but must be careful not to overplay their hand.

The health care law "is 50-50 with the public on a good day," said Davis. "You put that together with the IRS and it's combustible. For Republicans, I think they need to go a little slower and get some facts in."

"I don't think it's just a couple of underlings, but they don't have any smoking gun yet," he added.

Though it plays a crucial role in carrying out the health care law, the IRS is part of the back-office operation. IRS agents won't be setting up health insurance markets, and they won't have a say in which health plans people get to pick or what doctors they see.

However, agency officials will determine who is eligible for financial assistance under the law ? and who must pay penalties.

The reason the IRS is involved in what's essentially a social program is that lawmakers crafted the financial subsidies available under the health law as tax credits. The agency already administers another major social program, the earned income tax credit, which long ago surpassed welfare as the main source of government assistance for low-income families.

The IRS handles four major components of the health care law. The most important one is determining if individual Americans are entitled to new tax credits to help pay private insurance premiums. It's a complex calculation.

Keyed to income on a sliding scale, the credits are available starting in 2014 to households making up to four times the federal poverty level, or about $94,000 for a family of four. Individuals or families are eligible if they don't have affordable coverage on the job. But if you understate your income to get a bigger credit, you'll owe more taxes next year.

The agency is also in charge of assessing penalties on people who ignore the law's requirement to carry health insurance, which applies to virtually all Americans starting next year.

On the employer side, the IRS administers a tax credit to help small businesses with low-wage employees afford coverage, and it's also in charge of imposing penalties on companies with 50 or more employees that don't offer coverage.

Formlabs ships first Form 1 3D printer, Kickstarter backers should see theirs next week

Some might say it's been a long, long while since October -- with "some" referring to the swath of Kickstarter backers who've been waiting oh-so-patiently for a Form 1 to call their own. Formlabs has just confirmed via a company blog post that the very first Form 1 3D printer shipped out today, as the Collector's Edition Form 1 and half of the Initial Formation tier of pledges hopped on a variety of delivery trucks. The rest of you backers can expect to begin printing "by the end of next week." For those keeping count, the Form 1 is actually a few months behind schedule, but in all honesty, that's pretty good considering the up-and-down nature of crowdfunded projects that manage to find the limelight.

The outfit is reminding folks that Form 1 units are shipped as they're produced, fulfilling Kickstarter rewards and preorders by priority. Specifics on group deliveries won't come for a few more weeks, but those in the Bay Area can swing by Maker Faire (or ICFF if you're in the Big Apple) to catch an early glimpse. Oh, and if you're just now hearing of this thing? You can place a $3,299 order right now, but you probably won't get it until July. Them's the breaks, kids!
