How to Beat Roaming Fees While Traveling Abroad By

LAST week’s column suggested ways to save when calling home from abroad. This week I’ll tackle data roaming fees, which wireless providers charge when customers use their phones outside their service area. With travelers using smartphones and other wireless devices abroad in the same way as they do back home (to check e-mail, to update Facebook and Twitter and to pull up online maps), the skyrocketing fees are taking many by surprise.

Mistakes in Scientific Studies Surge

Since 2001, while the number of papers published in research journals has risen 44%, the number retracted has leapt more than 15-fold, data compiled for The Wall Street Journal by Thomson Reuters reveal.
(..)

Retractions related to fraud showed a more than sevenfold increase between 2004 and 2009, exceeding the twofold rise in retractions related to mere error, according to an analysis published in the Journal of Medical Ethics. The analyst, Grant Steen, reached that conclusion after studying 742 medicine and biology papers that were withdrawn from 2000 to 2010. He said 73.5% were retracted simply for error but 26.6% were retracted for fraud.
Another researcher, John Budd of the University of Missouri-Columbia, looked at roughly the same set of journals, though over a longer period, and also found the prevalence of scientific misconduct to be on the increase.

Après le Déluge, What?

Another great essay by Peggy Noonam of the Wall Street Journal...
Uvealblues

Riots and flash mobs have root causes that government can't reach.
The riots in Britain left some Americans shaken. In the affluence of the past 40 years, and with the rise of the jumbo jet, we became a nation of travelers. We have been to England, visited a lot of those neighborhoods. They were peaceful; now they're in flames. But something else raised our unease as we followed the story on TV and on the Net. I think there was a ping on the national radar. We saw something over there that in smaller ways we're starting to see over here.
(..)
The denunciations were swift and fierce. Max Hastings, in the conservative-populist Daily Mail: "The depressing truth is that at the bottom of our society is a layer of young people with no skills, education, values or aspirations. . . . Nobody has ever dared suggest to them that they need feel any allegiance to anything, least of all Britain or their community. . . . Not only do they know nothing of Britain's past, they care nothing for its present."
In the left-tilting Guardian, youth worker Shaun Bailey called the rioters opportunists. "Young people have been looting the shops they like: JD Sports and mobile phone shops have been hit, yet Waterstone's [a bookstore] has been left alone. These young people like trainers [sneakers] and iPhones; they are less interested in books. This is criminality in a raw form, not politics."
(..)
Where does that leave us? In a hard place, knowing in our guts that a lot of troubled kids are coming up, and not knowing what to do about it. The problem, at bottom, is love, something we never talk about in public policy discussions because it's too soft and can't be quantified or legislated. But little children without love and guidance are afraid. They're terrified—they have nothing solid in the world, which is a pretty scary place. So they never feel safe. As they grow, their fear becomes rage. Further on, the rage can be expressed in violence. This is especially true of boys, but it's increasingly true of girls.

Making Medical Donations Work


This is a great article about international medical aid.
Uvealblues
 “There are a slew of complex issues that make donations of any kind aside from financial  really poor practice for trying to help developing countries. When it comes to medical equipment donations, the consumables necessary to operate many of these machines, such as x-ray film, reagents, etc,  are often not considered prior to the donations; nor is life-cycle costing and maintenance and operational costing and support figured in. Subsequently we see a lot of discarded medical equipment lying around clinics, hospitals and dump sites in low-income countries we work in.”
Homira has identified a few ways that donations can go wrong.  There are plenty of others.  But you don’t have to donate cash to be useful.

In Sierra Leone, New Hope for Children and Pregnant

When I was in the maternity wards in Sierra Leone several years ago, the conditions were abysmal..it is good to hear that things are improving...

Sierra Leone is at the vanguard of a revolution — heavily subsidized for now by international donors — that appears to be substantially lessening health dangers here in one of the riskiest countries in the world for pregnant women and small children.
Country after country in sub-Saharan Africa has waived medical fees in recent years, particularly for women and children, and while experts acknowledge that many more people are getting care, they caution that it is still too early to declare that the efforts have measurably improved health on the continent.
In Sierra Leone, though, it seems clear that lives are being saved, providing an early and concrete lesson about the impact of making health care free for the very poor and vulnerable.

I’m just mature enough now to value sun protection and always grateful, sometimes to the point of pain, for gifts from those who have almost nothing.

Dankam Augmented Reality App for the Colorblind

Dankam is an augmented reality app for the iPhone that helps colorblind people discriminate between colors. Named after its author, Dan Kaminsky, it helps by automatically converting colors in the image which normally can’t be differentiated by people who are colorblind to colors which can be differentiated. It is optimized for the most common form of color blindness, anomalous trichromancy, in which differentiation between reds and greens is affected, but it also allows the user to tweak the filters. It can operate directly on the camera or on previously taken images. Also, a set of test images is included. The app is available for $2.99/EUR 2.39 in the app store.

Harnessing the Power of Feedback Loops

The basic premise is simple. Provide people with information about their actions in real time (or something close to it), then give them an opportunity to change those actions, pushing them toward better behaviors. Action, information, reaction. It’s the operating principle behind a home thermostat, which fires the furnace to maintain a specific temperature, or the consumption display in a Toyota Prius, which tends to turn drivers into so-called hypermilers trying to wring every last mile from the gas tank. But the simplicity of feedback loops is deceptive. They are in fact powerful tools that can help people change bad behavior patterns, even those that seem intractable. Just as important, they can be used to encourage good habits, turning progress itself into a reward. In other words, feedback loops change human behavior. And thanks to an explosion of new technology, the opportunity to put them into action in nearly every part of our lives is quickly becoming a reality.

An African Adventure, and a Revelation

Another important and excellent article about Africa from Nicholas Kristof of the New York Times. It is worth reading in its entirety in my opinion for anyone with an interest in Africa.
Uvealblues
Link
TAKE an American student and an American teacher who have never been near Africa before, lead them on a crazed “win a trip” journey through five particularly wretched countries, and what do you get?
Well, a few mishaps. There was that angry mob in Mauritania — who would have thought our cameras would upset people that much? And that bull elephant in Niger was equally inhospitable, although the giraffes seemed amiable as they approached to gawk at the strange white humans.
We encountered plenty of heartbreak, like the baby we met in Niger who was going blind from lack of vitamin A. In some places, we felt the gnawing disquiet of insecurity. The rise of banditry and a Qaeda network in West Africa forced us to take an armed escort across one particularly lawless stretch of “highway.”
Yet my travel buddies and I also found something far more significant on our journey: hope.

(..)
With Shawn, we drove south across the Mauritanian desert to Senegal, and then flew the following day to Niger — one of the poorest and most forlorn countries in the world. In the remote town of Dogon Doutchi, near the Nigerian border, we saw with heartbreaking clarity what doctors call severe acute malnutrition.
A 2-year-old child, Alou Muhammad, was lying nearly comatose on a cot in the local hospital, his ribs protruding, receiving fluid from an IV drip. Alou’s left eye had Bitot’s spots — signs of vitamin A deficiency that lead to blindness. At least 250,000 children go blind each year for lack of vitamin A, according to the W.H.O., and half of them die within a year of going blind.
(The cost of a vitamin A tablet is 2 cents and the kids need them every four to six months! uvealblues)
This was Saumya’s report:
"The local hospital was unlike anything I had ever seen. No hand sanitizer dispenser. No faces covered with scrub masks. No supply closet. No physicians streaming down the hallway in stark white coats.
"Alou was in pain, screaming 'Mama!' between sobs. I have seen malnourished children, but this was the first time I could count each rib."
(I have seen many such hospitals in Africa--uvealblues)
(..)
When I (Nicholas Kristof)
first backpacked through West Africa as a law student in 1982, what I found most wrenching were the ubiquitous blind beggars, victims of a disease called river blindness, spread by the bites of black flies. The flies carry parasites that grow into worms whose offspring eat away at the optic nerve and cause blindness, debilitating itching and excruciating pain.
“This was more painful than childbirth,” Fatouma Oumarou, a 70-year-old woman who had gone blind from the ailment, told us when we visited her village. At the peak of the disease, she recalled, much of the land in the area was left fallow because farmers did not dare work the area. In a nearby village, Moli, in a wildlife refuge, people told us that lions had killed a 15-year-old in the fields, but added, “We are more afraid of the black flies than of the lions.”
Yet these days river blindness is gone from this region, thanks partly to heroic work by Jimmy Carter, and to vast contributions of medicine by Merck. I asked villagers if they had ever heard of Jimmy Carter, and they shook their heads doubtfully — but his post-presidency work on global health had transformed their lives.
(Merck definitely deserves credit for this initiative--uvealblues)

Parasitic Worms May Offer Hope on MS

For people suffering from debilitating autoimmune disorders such as multiple sclerosis, there is growing evidence that help may be at hand from an unusual source: parasitic worms.
Link
In a U.S. study, early safety tests suggested the eggs of pig whipworms have anti-inflammatory properties, reducing the size of brain lesions in MS patients. A similar trial is under way in Denmark. And in Britain, academics at the University of Nottingham are studying the potential health benefits of hookworms, another type of parasitic worm.
If these trials prove successful, treatment with parasitic worms—known as helminthic therapy—could provide a simple, cheap, natural and controllable treatment for the debilitating condition, which affects 2.5 million people world-wide.
(..)
Whipworm eggs were taken from disease-free pigs and grown in Denmark in a clean environment by a German biotech company, OvaMed GmbH. Every two weeks over the course of three months, the patients in the study drank 2,500 of the eggs mixed into a sports drink. The eggs hatched in the patient's intestines and were killed by the immune system after about a week.
Patients who took part said the liquid was salty but didn't taste or smell unpleasant.
"It was like drinking a shot of salty water—you didn't notice the worms. It wasn't like there was anything chunky in it," explains Jim, 40, the first patient recruited for Dr. Fleming's safety study, who asked not to have his surname published.
"I signed up shortly after being diagnosed and didn't have a problem with it because I was pretty scared and, for me, ingesting worm eggs is just not a big deal."
(..)
The theory behind the HINT and WIRMS studies and others like them is known as "the hygiene hypothesis." This argues that developed countries such as the U.S., Europe and Japan have higher incidences of allergies and autoimmune diseases because the population has little or no exposure to parasites or infections.
In developing countries, where people are exposed to low-level infections or infestations, the rates of such diseases are much lower.

Giving Medical Receptionists Their Due


The importance of receptionists in healthcare settings is well illustrated in this article
Uvealblues

While much has been written about the role of doctors, nurses and other clinicians in the care of patients and their families, little attention has been paid to those individuals who make up the very front lines of health care. In almost every clinical practice, office receptionists and the professionals who do comparable work in hospitals, the ward clerks and unit secretaries, are the first people patients see. But serious research on their interactions with patients has been sparse at best.
Now the journal Social Science and Medicine has published a new study on the work of this group of professionals. Despite the stereotype that many receptionists bear as mere “gatekeepers” or even “the dragon behind the desk,” the study found that their responsibilities extend far beyond administrative duties. Ward clerks and office receptionists are a vital part of patient care.

The effectiveness of different approaches to funding and running health systems is often hotly debated, with every viewpoint seemingly able to marshal facts in support of their case.

Seeing the light preps brain for vision

Two studies—one with mice pups and one with tadpoles—show how exposure to light early in life helps organize and refine the circuitry of vision systems.
Link
David Berson, professor of neuroscience at Brown University, found light exposure can enhance how well mice organize the nerve endings from their left eye and their right eye in an area of the brain where they start out somewhat jumbled. Findings are published in Nature Neuroscience.
Neuroscientists had thought that mammals were unable to see at this stage, but a new type of light-sensitive cell that Berson discovered a decade ago turns out to let in the light.
Meanwhile, Berson’s colleague Carlos Aizenman, assistant professor of neuroscience, co-authored a paper in the Journal of Neuroscience showing that newborn tadpoles depend on light to coordinate and improve the response speed, strength, and reliability of a network of neurons in a vision-processing region of their brains.
“This is how activity is allowing visual circuits to refine and sort themselves out,” says Aizenman. “Activity is fine-tuning all these connections. It’s making the circuit function in a much more efficient, synchronous way.”

Genes Controlled with Light

Scientists have found a way to use light to control blood sugar in mice.
Link
Using a protein from the human retina, researchers in Switzerland have developed a method to control the expression of target genes with light. The scientists say the technology could be employed in the near term to boost the production of biological drugs, such as those for cancer, by enabling precise control over protein production. In the long term, cells engineered to carry the light-sensitive switch could be implanted into patients to produce a missing hormone, such as insulin, on demand.

You Say Potato, Scale Says Uh-Oh


Eating more potato chips and French fries is likely to lead to a bigger weight gain over the years than the weight change associated with eating more of other foods, new research indicates.
The study, from the New England Journal of Medicine, stands out because it quantifies how much weight a person is likely to gain or lose over four years based on one additional daily serving of a range of specific foods. Eating more potatoes correlated with a gain of 1.28 pounds, with French fries in particular associated with a 3.35-pound gain.
(..)
This type of study can't definitively say that certain foods cause weight changes. But it found one additional daily serving of potato chips was associated with a 1.69-pound gain; sugary drinks, processed meat and red meat were associated with about a one-pound gain. Eating more fruits and vegetables, nuts, whole grains and yogurt correlated with slight weight loss over four years. Big jumps in physical activity were associated with smaller weight gains, and increased TV-viewing with bigger gains.

A Defect That May Lead to a Masterpiece


In learning to draw or paint, it helps to have a sense of composition, color and originality.
And depth perception? Maybe not so much, neuroscientists are now suggesting. Instead, so-called stereo blindness — in which the eyes are out of alignment so the brain cannot fuse the images from each one — may actually be an asset.
(..)
Dr. Livingstone and her colleagues first suspected a connection between artistic talent and stereo blindness when they examined 36 self-portraits by Rembrandt and found that his right eye was noticeably deviated in 35 of them. (That finding was published in The New England Journal of Medicine in 2004.) They wondered how widespread the phenomenon might be.
The idea that some artists have a fundamental visual defect seems counterintuitive, said a co-author of both studies, Bevil R. Conway, a stereo-blind artist who teaches neuroscience at Wellesley College.
“But I always found it easy to draw,” he said, “not because of dexterity, but because when I looked at a scene the relative size and spatial relationships of objects seemed obvious and related immediately to their representation on a flat sheet of paper.”
An expert not involved in the new research, Susan R. Barry, a professor of neuroscience at Mount Holyoke College, said she thought the authors were “on to something.”
Dr. Barry is the author of “Fixing My Gaze” (Basic Books, 2009), an account of how she regained stereo vision at age 50 using vision therapy. “I have received hundreds of e-mails from people who are stereo blind, and it seems a disproportionate number are artists. Not being able to see in stereo might bias some people toward art.”
Ten percent of people develop various degrees of stereo blindness in early childhood because of visual defects that do not allow both eyes to line up, Dr. Barry said. Some have weak stereo that comes and goes with fatigue, while others completely lack what she calls the “palpable volumes of space” that come with stereo. Stereo-blind people learn to navigate by using monocular cues and never know what they are missing.

Dr. Gather and Dr. Yun genetically programmed cells to produce green fluorescent proteins. They then placed such a cell in a cavity with two tiny, parallel mirrors spaced seven ten-thousandths of an inch apart, large enough to hold exactly one cell. Using a microscope, they exposed the cell to pulses of blue light.
When exposed to the pulses, the fluorescent proteins in the cells started to emit green fluorescent light. The light bounced back and forth between the mirrors, amplifying to generate a bright, unidirectional laser light.

Don’t Quit This Day Job


I’M a doctor and a mother of four, and I’ve always practiced medicine full time. When I took my board exams in 1987, female doctors were still uncommon, and we were determined to work as hard as any of the men.
Today, however, increasing numbers of doctors — mostly women — decide to work part time or leave the profession. Since 2005 the part-time physician workforce has expanded by 62 percent, according to recent survey data from the American Medical Group Association, with nearly 4 in 10 female doctors between the ages of 35 and 44 reporting in 2010 that they worked part time.
(..)
The Association of American Medical Colleges estimates that, 15 years from now, with the ranks of insured patients expanding, we will face a shortage of up to 150,000 doctors. As many doctors near retirement and aging baby boomers need more and more medical care, the shortage gets worse each year.
The decline in doctors’ pay is part of the problem. As we look at Medicare and Medicaid spending cuts, we need to be careful not to drive the best of the next generation away from medicine and into, say, investment banking.

Surgeons Who Burn the Midnight Oil

This post highlights one of the key ingredients in any successful surgery in my opinion:
The reliability of the surgical team
Uvealblues
This week, The Journal of the American Medical Association published a third study on the topic. Unlike the other two studies, which examined the outcomes of abdominal transplants, this one focused on transplant operations performed in the chest. And rather than reviewing the results of a single institution, as the previous investigators did, this most recent study took into account all of the almost 30,000 heart and lung transplants performed in the United States over 10 years.
The results surprised the researchers. Patients fared essentially the same whether the transplants were performed during the day or at night. Contrary to conventional wisdom, patient outcomes had little to do with the time of the operation or the fatigue of the surgeon. Rather, they seemed to hinge on the reliability of the surgical team.

Study Questions Treatment Used in Heart Disease

WASHINGTON — Lowering bad cholesterol levels reduces heart attack risks, and researchers have long hoped that raising good cholesterol would help, too. Surprising results from a large government study announced on Thursday suggest that this hope may be misplaced.
(..)

The results are part of a string of studies that suggest that what doctors thought they knew about cholesterol may be wrong. Studies that track patients over time have for decades shown that patients with higher levels of high-density lipoproteins (H.D.L., or good cholesterol) tend to live longer and have fewer heart problems than those with lower levels of this cholesterol.
Not surprisingly, doctors thought that if they could raise H.D.L. levels, their patients would benefit. So far, that assumption is not panning out. Nobody knows why.

Commodity Prices and Paradigm Shifts

But there is a paradigm shift underway, maybe even the mother of all paradigm shifts, and it is coming from a direction where Grantham and other bears are not looking.
The real paradigm shift, or more like a paradigm drift, because it is slowly enveloping us, is that we are moving toward preferences and lifestyle where we will simply consume less. A lot less. Like improvements in efficiency, changes in tastes and preferences are nothing new, but this time is different.

I have already discussed this in previous posts on life in the experience machine and the world of smaller scale. In The Accidental Egalitarian I make the point that with the increased focus on technology – where we spend more and more of our time on our cell phone, doing emails, watching DVDs and surfing the web – there is less of a difference between how the super rich and the reasonably well off spend their time hour by hour during their typical days. The point of that post is that in practical terms the income gap is not as large as it might seem; that several orders of magnitude differences in income don’t make all that much difference in what these people do with their time. The point here is a corollary: those activities do not require much in the way of material consumption, and therefore not much in terms of commodities.

People who are staring at a tsunami of demand for commodities from the developing world and predicting a doomsday of $400 oil and $4000 gold are missing the longer-term retreating tide of demand as citizens of the developed world actually demand decreasing amounts of energy, large goods, and heavy infrastructure. We won't be packing up and moving to Mars, as the science fiction solutions to resource depletion propose. We will pack up and move into the virtual world.

The Body Weight-Muscle Mismatch


How muscles recognize changes in body weight — and why sometimes they don’t — are questions that are likely to have relevance for people, and not just lab rats. Studies have found that “individuals who are extremely overweight often complain that moving is difficult,” said James H. Marden, a professor of biology at Penn State and co-author of the rat study. It’s possible that their muscular strength is not keeping pace with their growing body size.
But why there should be such a mismatch between body weight and muscle strength is unknown.

Invisibility Cloak: Scientists Achieve Optical Invisibility in Visible Light Range of Spectrum

ScienceDaily (May 18, 2011) — "Seeing something invisible with your own eyes is an exciting experience," say Joachim Fischer and Tolga Ergin. For about one year, both physicists and members of the team of Professor Martin Wegener at KIT's Center for Functional Nanostructures (CFN) have worked on refining the structure of the Karlsruhe invisibility cloak to such an extent that it is also effective in the visible spectral range.

In invisibility cloaks, light waves are guided by the material such that they leave the invisibility cloak again as if they had never been in contact with the object to be disguised. Consequently, the object is invisible to the observer. The exotic optical properties of the camouflaging material are calculated using complex mathematical tools.

An Electrical Jolt for Paralysis Research

In a potential breakthrough for the treatment of spinal-cord injuries, a man paralyzed below the chest has regained some ability to move and stand through the use of electrical stimulation coupled with intense physical rehabilitation—a combination previously shown to work only in animals.
Link

"I didn't move a toe for four years," said Mr. Summers. "I stood up on the third day they turned the stimulator on," he said. "There are not enough words to describe how I felt."
Under stimulation, Mr. Summers is also able to voluntarily move his hips, ankles and toes. And he has gotten back some bladder and sexual function.

"This probably changes the field fairly dramatically," said Ronald Reeves, vice chairman of the department of physical medicine and rehabilitation at the Mayo Clinic in Rochester, Minn., who wasn't involved in the research. "It's the first time that there's compelling scientific evidence that you can, with the electrostimulation of the spinal cord, create a favorable motor response."
As in most spine injuries, Mr. Summers' spinal cord wasn't totally severed, though the damage was severe enough to prevent the brain from signaling the spinal cord to initiate movement.

Hospitals Misleading Patients About Benefits of Robotic Surgery, Study Suggests

ScienceDaily (May 19, 2011) — An estimated four in 10 hospital websites in the United States publicize the use of robotic surgery, with the lion's share touting its clinical superiority despite a lack of scientific evidence that robotic surgery is any better than conventional operations, a new Johns Hopkins study finds.

One Runner’s Suffering Is Another’s Inspiration

Do we run because we like the pain?
(..)

The problem, it seems, is that we have only one word, “pain,” for something that should have many descriptors, as in the old legend that Eskimos have many words for snow.
Markus Amann, a muscle researcher at the University of Utah and the Salt Lake City Veterans Affairs Medical Center, says that what actually stops or slows most people during exercise is fatigue, not pain. It is regulated by a group of nerve fibers, the so-called ergoreceptors, that respond to a combination of metabolites released by muscles during exercise — calcium ions, lactate, hydrogen ions. In response, the brain “decides” to slow down, Dr. Amann explained.

With World Support, an Ambitious Plan Would Vaccinate 90 Percent of Infants

Haiti, which did a poor job of vaccinating its children even before the 2010 earthquake, has come up with a plan to immunize 90 percent of its newborns by 2015, the Pan American Health Organization announced last week.

The country now needs over $100 million to carry it out.

The Value of Comparison

The recently released CATT trial showed that Lucentis and  Avastin were essentially equivalent in treating wet ARMD. The fact of the matter is that retina specialists using avastin have saved Medicare and insurance companies millions upon millions of dollars. In response, ironically, Medicare decreased the already minimal reimbursement for the injection component of administering the medication by doctors. One could have further argued that Medicare should indeed have put into place an incentive program to reward physicians  that saved Medicare so much money by using avastin!!

Before you take a drug or undergo a medical procedure, wouldn’t you want to be sure it is the most effective and, if possible, the least costly available?
That is the idea behind so-called comparative effective research that is part of the health care reform law. Unfortunately, in the effort to win Republican support (support that never materialized), the bill’s sponsors agreed to bar Medicare from using comparative studies to determine which treatments to pay for. Critics charged it would mean more bureaucratic interference and a step toward socialized medicine.
The shortsightedness of that thinking was made clear last month when results were released of a government-sponsored study comparing two drug treatments for macular degeneration, which is the leading cause of vision loss and blindness in older Americans.
Both drugs are made by Genentech. Even so, there is a vast difference in their cost and, until now, uncertainty about their relative effectiveness.
(..)
Clinical trials sponsored by Genentech showed that Lucentis is highly effective in preserving and improving vision. The cost per monthly dose, however, was set by the company at $2,000. Enterprising eye doctors quickly realized they could get similar results by using Avastin in small doses. Avastin can cost thousands of dollars a month for the quantities used to treat cancer, but the doses suitable for injection into the eye cost about $50 a month.

An Eye for an Eye: Iran's Blinding Justice System

Iran's judiciary has postponed the blinding of a man as punishment for throwing acid in the face of a young woman in 2004, after she rejected his offer of marriage. The delay came in the face of mounting outcry from both inside Iran and the West over the sentence, which is permissible under qesas, a principle of Islamic law allowing victims analogous retribution for violent crimes.

Bahrami, who was scheduled to administer the blinding drops to an anesthetized Movahedi herself, learned of the delay outside the Judiciary Hospital in Tehran. Human-rights groups and Western governments pleaded with Iranian authorities last week to call off the punishment

New Strategies to Revive Victims of Cardiac Arrest; Improving Odds of Survival Without Brain Damage

A little-known device is shaking conventional wisdom for reviving people who suffer sudden cardiac arrest: People may be able to go much longer without a pulse than the 20 minutes previously believed.
The capnograph, which measures carbon dioxide being expelled from the mouth of the patient, can tell rescuers when further efforts at cardiopulmonary resuscitation, or CPR, are futile or whether they should be continued. It is the latest effort that cardiology experts and emergency teams are devising that aim to improve a patient's odds.

When Mama Ain’t Happy

About half of children with depressed mothers develop depression themselves, three times the typical risk, the column reports.  Children of depressed mothers are also more likely to be anxious, irritable and disruptive than other kids. They’re also more apt to have trouble in school and turn to substance abuse later in life. Many perpetuate the cycle with their own kids.
But successfully treating a mother for depression can provide long-lasting benefits for her children’s mental health, new research shows.

AIDS Study Marks Prevention Breakthrough


Antiretroviral Drugs Are Shown to Make Patients Far Less Infectious

Treating AIDS patients with antiretroviral drugs makes them strikingly less infectious, researchers said Thursday, in a landmark finding that is likely to reinvigorate efforts to slow the pandemic.
The results were so overwhelming that an independent panel monitoring the research recommended the results be released four years before the large, multi-country study had been scheduled to end.
"This new finding convincingly demonstrates that treating the infected individual—and doing so sooner rather than later—can have a major impact on reducing HIV transmission," said Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, which provided most of the funding for the study.

Tiny Fractal-Shaped Eye Implants Could Mimic Neurons, Allowing Blind Patients to See

Retinal implants can let blind people see, but to be truly effective, they should be adapted to the human eye’s unique structure, according to one researcher. Tiny clusters of material that self-assemble into fractals could help with this, strengthening the connections between an implant and a patient’s healthy neurons.
Some vision disorders, like macular degeneration, damage the eyes’ rods and cones but leave the neurons intact. Implants work by communicating with those neurons, sending visual information to the brain to be processed. But camera chips and eyes do not work the same way, and there are insufficient connections between the neurons and the implanted photodiode light receptors.

Doing More Than Praying for Rain

In the United States, insurance against extreme weather is seen as so important that Washington subsidizes it highly and requires it for farmers who want other government benefits.  If American farmers need weather insurance, African peasant farmers need it even more.  But the vast majority of African peasant farmers have no opportunity to insure their crops.
Link 

Virtually all small farmers in Africa depend on rain for irrigation.  Most have no safety net —  a farmer planting an acre of corn twice a year can find her family nearly destitute if the crop fails because of drought early in the planting season, or too much rain later on.   She will have invested everything she has in seeds and fertilizer.  There will be nothing left for the next planting season.
Farming an acre of grain with nothing more than a strong back and a hoe has always been precarious, but now more so than ever, because of climate change.  A report from the International Food Policy Research Institute estimates that grain crop yields in Africa will shrink substantially by 2050, there will be 10 million more malnourished children than there are today and Africans on average will be eating 21 percent fewer calories than they do today.  Small farmers around the world need many different things to help them survive climate change:  seeds resistant to extreme weather and pests, cheap irrigation systems, and better agricultural infrastructure, such as more feeder roads.  But one thing that can help small farmers now is insurance.

Just How Dangerous Is Sitting All Day?

Brightly Colored Bird Feathers Inspire New Kind of Laser

A new kind of laser captures light just like some colorful bird feathers. The device mimics the nanoscale structure of colorful feathers to make high-intensity laser light with almost any color.
Link 
(..)
Certain brightly colored birds, like kingfishers or parrots, have feathers embedded with a not-quite-random arrangement of air pockets. Wavelengths of light that are related to the distance between the air pockets get scattered and built up more than others, giving the feathers their characteristic colors.
“After we learned this, we said, ‘Oh, that’s a smart idea!’” Cao said. “Can we use this to improve our lasers? Maybe we can use short-range order to enhance light confinement and make lasing more efficient.”

The SEAL Sensibility

From a member of the elite force, an inside look at the brutal training and secret work of the commandos who got Osama bin Laden.

Link 

Some men who seemed impossibly weak at the beginning of SEAL training—men who puked on runs and had trouble with pull-ups—made it. Some men who were skinny and short and whose teeth chattered just looking at the ocean also made it. Some men who were visibly afraid, sometimes to the point of shaking, made it too.
Almost all the men who survived possessed one common quality. Even in great pain, faced with the test of their lives, they had the ability to step outside of their own pain, put aside their own fear and ask: How can I help the guy next to me? They had more than the "fist" of courage and physical strength. They also had a heart large enough to think about others, to dedicate themselves to a higher purpose.
SEALS

Seals during training exercises
SEALs are capable of great violence, but that's not what makes them truly special. Given two weeks of training and a bunch of rifles, any reasonably fit group of 16 athletes (the size of a SEAL platoon) can be trained to do harm. What distinguishes SEALs is that they can be thoughtful, disciplined and proportional in the use of force.
