Read the text below and answer the following
question based on it.
Global sleeping patterns revealed by app data.
It showed the Dutch have nearly an hour more in bed every
night than people in Singapore or Japan.
The study, published in Science Advances, also found
women routinely get more sleep than men, with middle-aged
men getting the least of all.
The researchers say the findings could be used to deal with
the "global sleep crisis".
The study found people in Japan and Singapore had an
average of seven hours and 24 minutes sleep while the
people in the Netherlands had eight hours and 12 minutes.
People in the UK averaged just under eight hours - a
smidgen less than the French.
The later a country stays up into the night, the less sleep it
gets. But what time a country wakes up seems to have little
effect on sleep duration.
Prof Daniel Forger, one of the researchers, said there was a
conflict between our desire to stay up late and our bodies
urging us to get up in the morning.
The study also showed women had about 30 minutes more
per night in bed than men, particularly between the ages of
30 and 60.
And that people who spend the most time in natural sunlight
tended to go to bed earlier.
A strong effect of age on sleep was also detected. A wide
range of sleep and wake-up times was found in young
people but "that really narrows in old age," said Prof Forger.
"It highlights that although our body clocks are programming
us to do certain things, we can't as we're ruled by social
circumstances.
"We won't know the long-term consequences of this for
many years."

Read the text below and answer the following
question based on it.
An accident took her sight 21 years ago;
another just gave it back
After a car accident injured her spine in 1995, Mary Ann
Franco lost her vision. But after being blind for 21 years, the
Florida woman fell in her home and hurt her neck ... and
woke up from the ensuing spinal surgery on April 6 with the
ability to see. "Out the window, I could see the trees. I could
see the houses and stuff," Franco tells WPBF. Oddly,
Franco was colorblind before her car accident, and now she
can also see colors. The neurosurgeon who operated on her
says he has no scientific explanation for what happened—
Dr. John Afshar tells ABC News it's a "true miracle"—but he
has an idea. If an artery in Franco's spine was "kinked" in
the car accident, restricting the flow of blood to the part of
her brain that handles vision, he may have inadvertently
"unkinked" the same artery during the recent surgery, he
theorizes. "And when we gave that extra amount of blood
flow by unkinking the vessel, it could have reestablished the
blood flow," he tells WPBF, though he notes that none of
this is certain. But an explanation doesn't matter much to
Franco: "The sun is coming through the trees," she said on
a recent morning. "Oh God, it’s so wonderful to see." Nature
isn't the only sight for her to behold: Franco has seven
grandchildren and two great grandchildren who WPBF notes
she has hugged and kissed but never seen.

Read the text below and answer the following
question based on it.
Lack of autonomy and respect threatens
'doctorness,' physicians say.
Doctors say that “doctorness”—the traditional way that
physicians practice medicine—is threatened, a new study
reported. These threats include the increasing complexity of
the health care landscape, combined with today’s
technology-enabled consumer, according to the “Truth
About Doctors” study conducted by marketing services firm
McCann.
The study found that the pressures of today’s world have
not only stolen time and autonomy from doctors, but have
simultaneously demanded they do more on someone else’s
agenda.
“The autonomous, entrepreneurial role the doctor has
played in the past has changed dramatically. In the last five
years, doctors have gone from being the lynchpin in the
health care system to a devalued cog in a larger wheel,”
said co-author of the study Hilary Gentile.
The research involved interviews with 450 doctors across
the United States.
Study co-author Laura Simpson added, “Modern-day
doctors have become trapped in a paradoxical standard
where they’re expected to forge a warm relationship with
patients, yet operate with the cold precision of a machine. In
our real-time, know-it-all culture, their authority and respect
are eroding right under their feet.”
In addition to the physician interviews, this research
revealed that nearly one-third of Americans between the
ages of 18 and 34 think they could be doctors with little or
no training.
“People think that because they can go on WebMD, they
understand what we understand,” said one physician quoted
in the report. “We have studied and seen so much, but
people just don't value or respect that anymore.”
“Of doctors who said that, on average, technology such as
WebMD and wearable devices are bad for patients, the
number one risk they cited of this technology is that patients
misdiagnose themselves (74%),” Ms. Simpson said. “Fiftyseven percent also said that patients don’t take the doctor’s
advice because they think they know better.”

Women taking pill more likely to be
treated for depression, study finds
Millions of women worldwide use hormonal contraceptives,
and there have long been reports that they can affect mood.
A research project was launched in Denmark to look at the
scale of the problem, involving the medical records of more
than a million women and adolescent girls.
It found that those on the combined pill were 23% more
likely to be prescribed an antidepressant by their doctor,
most commonly in the first six months after starting on the
pill. Women on the progestin-only pills, a synthetic form of
the hormone progesterone, were 34% more likely to take
antidepressants or get a first diagnosis of depression than
those not on hormonal contraception.
The study found that not only women taking pills but also
those with implants, patches and intrauterine devices were
affected.
Adolescent girls appeared to be at highest risk. Those
taking combined pills were 80% more likely and those on
progestin-only pills more than twice as likely to be
prescribed an antidepressant than their peers who were not
on the pill.
The researchers, Øjvind Lidegaard of the University of
Copenhagen and colleagues, point out that women are
twice as likely to suffer from depression in their lifetime as
men, though rates are equal before puberty. The fluctuating
levels of the two female sex hormones, oestrogen and
progesterone, have been implicated. Studies have
suggested raised progesterone levels in particular may
lower mood.
The impact of low-dose hormonal contraception on mood
and possibly depression has not been fully studied, the
authors say. They used registry data in Denmark on more
than a million women and adolescent girls aged between 15
and 34. They were followed up from 2000 until 2013 with an
average follow-up of 6.4 years.
The authors call for more studies to investigate this possible
side-effect of the pill.

Chronic loneliness is as bad for our health as smoking 15 cigarettes a day and as damaging as obesity and physical inactivity. It is linked with depression, dementia and high blood pressure alongside a number of other conditions. Loneliness impacts on our struggling health and social care system, with evidence showing that those living with loneliness are far more likely to visit their local doctor or A&E. New research shows the health cost alone of loneliness is equivalent to some £12,000 per person over 15 years.
National and local policymakers are now waking up. Health and wellbeing boards across England are making loneliness a priority and the Welsh and Scottish governments have recently announced commitments to develop national cross-governmental strategies to address loneliness and social isolation.
We are calling on the UK government to follow suit and commit to the development of a UK-wide strategy for tackling loneliness and social isolation to help end this growing crisis.

The material was designed to be embedded with medicallyuseful electronics, such as conductive wires, semiconductor chips, LED lights, and temperature sensors, according to a study published online December 7, 2015 in the journal Advanced Materials.
Electronics coated in the hydrogel could be placed not only on the surface of the skin but also inside the body—such as implanted biocompatible glucose sensors or soft, compliant neural probes, the researchers wrote.
“Electronics are usually hard and dry, but the human body is soft and wet. These two systems have drastically different properties,” said lead investigator Xuanhe Zhao, Associate Professor in MIT’s Department of Mechanical Engineering.
Dr. Zhao explained, “If you want to put electronics in close contact with the human body for applications such as health care monitoring and drug delivery, it is highly desirable to make the electronic devices soft and stretchable to fit the environment of the human body. That’s the motivation for stretchable hydrogel electronics.”
Current hydrogels are often brittle and made of degradable biomaterials that don’t last long, he explained. So, his team designed a hydrogel that is not only as flexible as human soft tissues, but can bond strongly to non-porous surfaces such as gold, titanium, aluminum, silicon, glass, and ceramic.

The material was designed to be embedded with medicallyuseful electronics, such as conductive wires, semiconductor chips, LED lights, and temperature sensors, according to a study published online December 7, 2015 in the journal Advanced Materials.
Electronics coated in the hydrogel could be placed not only on the surface of the skin but also inside the body—such as implanted biocompatible glucose sensors or soft, compliant neural probes, the researchers wrote.
“Electronics are usually hard and dry, but the human body is soft and wet. These two systems have drastically different properties,” said lead investigator Xuanhe Zhao, Associate Professor in MIT’s Department of Mechanical Engineering.
Dr. Zhao explained, “If you want to put electronics in close contact with the human body for applications such as health care monitoring and drug delivery, it is highly desirable to make the electronic devices soft and stretchable to fit the environment of the human body. That’s the motivation for stretchable hydrogel electronics.”
Current hydrogels are often brittle and made of degradable biomaterials that don’t last long, he explained. So, his team designed a hydrogel that is not only as flexible as human soft tissues, but can bond strongly to non-porous surfaces such as gold, titanium, aluminum, silicon, glass, and ceramic.

Stretchable hydrogel can be used as a 'smart bandage' and delivery vehicle for medical devices.
Engineers at MIT have developed an elastic yet sturdy hydrogel material that can be used as flexible, biocompatible wound dressing and as a smart delivery method for drugs or medical devices.The material was designed to be embedded with medicallyuseful electronics, such as conductive wires, semiconductor chips, LED lights, and temperature sensors, according to a study published online December 7, 2015 in the journal Advanced Materials.
