Bipolar and Having a high IQ level
Bipolar could be the ‘price humans pay for higher intelligence and creativity’

Through studying children aged eight and then in their early twenties Glasgow, Bristol, Cardiff and Texas made some startling discoveries.
Participants in the study who came in the top 10 per cent of manic traits in adulthood had a childhood IQ nearly 10 points higher than those who scored in the bottom 10 per cent of manic traits.
Researchers believe their findings suggest that bipolar disorder may have been ‘selected through generations’.
‘One possibility is that serious disorders of mood such as bipolar disorder are the price that human beings have had to pay for more adaptive traits such as intelligence, creativity and verbal proficiency,’ said University of Glasgow psychiatry professor Daniel Smith.
It is hoped the study, which was published in the British Journal of Psychiatry, will help in earlier detection of mood disorders.
One in every 100 British adults is thought to suffer from bipolar disorder, with many celebrities such as Steven Fry and Russell Brand being open about being afflicted by the condition.

31 survive as two planes crash in mid-air-
7 die, 31 survive as two planes crash in mid-air
TOPICS
Over western Slovakia, killing seven people, officials said.
Two planes carrying dozens of parachutists collided in mid-air on
Thursday over western Slovakia, killing seven people, officials said.
Thirty-one others on board survived by jumping out with their
parachutes.
The crash took place on Thursday morning near the village of Cerveny
Kamen, said Zuzana Farkasova, a spokeswoman for the Slovak
fire-fighters.
Rescue workers used helicopters to reach the forested crash site in the
White Carpathians mountain range that forms the border with the Czech
Republic.
The two Czech-made L-410 transport planes collided at an altitude of
1,500 meters, said Juraj Denes, an official with the Slovak Air and
Naval Investigations Bureau, a government agency that investigates plane
crashes.
Peter Bubla, spokesman for the Health Ministry, said 38 people were on
board the two planes and 31 survived. Five people needed some medical
treatment but nobody was hospitalised, he said.
Some on board jumped out even after the planes collided, according to
Interior Minister Robert Kalinak. “The 31 parachutists managed to jump
out from the falling planes and survived,” Mr. Kalinak told the TA3 news
television station as he visited the crash site. “They all landed
safely. It’s a small miracle.”
The dead included the two crew members from both planes and three
parachutists, Juraj Gyenes, another official at the aviation
investigations agency, told TA3. TA3 reported the parachutists were
training for this weekend’s air show in nearby Slavnica. “All of a
sudden, I heard a big blow,” one witness told TASR, the Slovak news
agency, in a news video. “Then it roared. I thought some pieces were
falling, but it could be the parachutists.”
Kalinak and Slovak Health Minister Viliam Cislak visited the crash site,
where wreckage from the planes smouldered among the dense mountain
forest.

Osteopathy for kids with special needs
World Osteopath Students Association holds workshop
Among issues faced by Children with Special Needs is
that of restricted mobility and difficulty in digestion. At a five-day
workshop at Satya Special School in Puducherry, volunteers from the
Etudiants Ostéopathes du Monde (EOM) or the World Osteopath Students
Association in France demonstrated how osteopathy, a medical field which
is still fairly new in India, can help deal with such ailments.
The
EOM consists of current and former students from the Institut Supérieur
d’Ostéopathie Paris (ISO Paris) and promotes osteopathy especially in
countries where there is little access to it through yearly projects.
The association raises funds for the projects through activities and by
conducting treatments in France. In the past, the association has worked
in countries such as Senegal and Morocco.
The team,
consisting of seven osteopaths and one photographer from EOM, has been
spending around three weeks in Puducherry and was at the Satya Special
School last week.
According to the Medical News Today
website, “osteopathy is a form of drug-free non-invasive manual
medicine that focuses on total body health by treating and strengthening
the musculoskeletal framework, which includes the joints, muscles and
spine.
Its aim is to positively affect the body’s nervous, circulatory and lymphatic systems.”
Osteopathy
works on the principle of interconnectedness of organs, tissues and
other parts of the body, according to Gabriel Plessier, one of the team
members from EOM.
“We work alongside
physiotherapists. Osteopathy helps the body be better prepared to
receive physical therapy. Children with Special Needs can develop
locking of joints and abnormal motility patterns in the small intestine
leading to issues with digestion. Osteopathy treats every tissue in the
body so it can move at its best capability. Almost half of all
osteopaths in France are physiotherapists,” he added.
“Children
with Special Needs have a physical expression of stress. When the
pericardium tissue around the heart is irritated, it leads to a ripple
effect for these children, affecting other body parts. In osteopathy,
the child is made to relax. Osteopathy also helps relieve facial
tightness and postural dysfunction,” said Mr. Plessier.
About
osteopaths, Mr. Plessier said, “While we cannot prescribe drugs or
undertake surgery, we work with our hands and our sense of touch. We
study about every element of the body and its interaction.”
Role of parents
Parents
were also present during the workshop to help the osteopaths while
treating the children. As the children trust their parents, it is better
to involve them in the treatment, said Mr. Plessier. The parents were
taught simple exercises and massages to aid mobility which they could
use at home with their children. Students of physiotherapy from Sri
Venkateshwaraa Medical College Hospital and Research Centre who are
doing their internship at Satya Special School also got a chance to
learn more about osteopathy.
Chitra Shah, director,
Satya Special School, said, “We need to concentrate more on therapeutic
intervention for Children with Special Needs. There is a huge gap
between surgical intervention and therapeutic intervention in paediatric
care. Osteopathy is looking at the issues these children face from a
holistic point of view. We want to incorporate fields like osteopathy
treatment in our school curriculum.”
The Satya
Special School is also exploring if tele-therapy can be introduced, and
possible tie-ups with colleges abroad to keep up with the latest trends
in care for Children with Special Needs and special education.

RELATED
Researchers at Cambridge University have developed a smartphone game that can help reduce symptoms of schizophrenia.
The game, called Wizard, helps those diagnosed with schizophrenia practice day-to-day cognitive skills that keep their brains sharp.
It has been designed to help deal with symptoms such as paranoia and hallucinations, and has been paired with the popular brain-training app, Peak.
"In conjunction with medication and current psychological therapies, (Wizard) could help people with schizophrenia minimise the impact of their illness in their everyday life," The Guardian quoted a research team member as saying.
The study found that 22 patients who played the memory game committed fewer errors and needed less effort to remember the location of different patterns of specific tests.
Improvements in memory retention, remembering dates and times and understanding the context, conversation and other forms of communication are all categories that improved when patients used the game on a regular basis.
Wizard is currently available for iOS platform only, and soon it would be available for Android.
The study was published in Philosophical Transactions of the Royal Society.

Gene drive': Scientists sound alarm over supercharged GM organisms which could spread in the wild and cause environmental disasters
The development of so-called 'gene drive' technology promises to revolutionise medicine and agriculture
A powerful new technique for generating “supercharged” genetically
modified organisms that can spread rapidly in the wild has caused alarm
among scientists who fear that it may be misused, accidentally or
deliberately, and cause a health emergency or environmental disaster.
The development of so-called “gene drive” technology promises to
revolutionise medicine and agriculture because it can in theory stop the
spread of mosquito-borne illnesses, such as malaria and yellow fever,
as well as eliminate crop pests and invasive species such as rats and
cane toads.However, scientists at the forefront of the development believe that in the wrong hands gene-drive technology poses a serious threat to the environment and human health if accidentally or deliberately released from a laboratory without adequate safeguards. Some believe it could even be used as a terrorist bio-weapon directed against people or livestock because gene drives – which enable GM genes to spread rapidly like a viral infection within a population – will eventually be easy and cheap to generate.
There is no compelling evidence to suggest that genetically modified crops are any more harmful than conventionally grown food (Getty)
“Just as gene drives can make mosquitoes unfit for hosting and spreading the malaria parasite, they could conceivably be designed with gene drives carrying cargo for delivering lethal bacterial toxins to humans,” said David Gurwitz, a geneticist at Tel Aviv University in Israel.
A group of senior geneticists have called for international safeguards to apply to researchers who want to develop gene drives, with strict security measures placed on laboratories to prevent the accidental escape of “supercharged” GM organisms that are able to spread rapidly in the wild.
Last week the US National Academy of Sciences initiated a wide-ranging review of gene-drive technology in “non-human organisms” and in this week’s journal Science a group of 27 leading geneticists call on the scientific community to be open and transparent about both the risks and benefits of gene drives.
“They have tremendous potential to address global problems in health, agriculture and conservation but their capacity to alter wild populations outside the laboratory demands caution,” the scientists say.
The researchers have drawn up a minimum set of safety rules to protect against laboratory escapes and have called for a public debate on the potential benefits as well as risks of a technology that allows geneticists to rapidly accelerate the inheritance of GM traits throughout an animal population within just a few generations.
Researchers have likened gene-drive technology to a nuclear chain reaction because it allows GM genes to be amplified within a breeding population of insects or other animals without any further intervention once the trait has been initially introduced. This is the case even if the trait is non-beneficial to the organism.
Laboratory experiments on fruit flies have shown that a modified gene introduced into one individual fly can take just a few generations to “infect” practically every other fly in the breeding population, in defiance of the normal rules of genetics which dictate a far slower spread.
Kevin Esvelt, a gene-drive expert at the Wyss Institute at Harvard Medical School in Boston, said the technology was developed theoretically about 10 years ago but it has only been made possible in the lab in the past two years with the discovery of the sophisticated gene-editing tool Crispr/Cas9.
Dr Esvelt explained that gene drives relied on a “cassette” of genetic elements that allowed a genetically modified gene to jump from one chromosome to another within the same individual so that eventually all of the sperm or eggs of the animal carried the GM trait, rather than half. This means that virtually none of the offspring is eventually free of an introduced GM trait.
Gene drives could benefit human health by altering insect populations that spread human diseases, such as mosquitoes that transmit malaria, dengue, chikungunya and Lyme disease, so that they were no longer a threat, he said.
Debate still rages over genetically modified food after nearly 20 years (Getty)

Hemlatha Annamalai and P Bala's Ampere Vehicles makes e-vehicles in Coimbatore. Do they have a strong business case?
Ratan Tata, chairman emeritus of Tata Sons, is a venerable name in the world of startups and angel investors.
He has invested in a string of e-commerce startups and one automobile company: Coimbatore-based Ampere Vehicles, the maker of electric two- and three-wheelers.
The company's factory is in the midst of a coconut farm, away from downtown Coimbatore.
The entrance is guarded not by an electronically-controlled barricade, but by a hand-operated wooden barrier, which a middle-aged guard lifts by untying a knot from a coconut tree.
Inside, all is quiet: there's no deafening noise of machines.
Hemlatha Annamalai, Ampere's CEO, dressed in dark blue trousers and a
blue shirt, sits on a sofa from where she can see the verdant coconut
trees.
Annamalai, who belongs to Chennai and studied at the Government College of Technology at Coimbatore, moved to Singapore after her marriage to P Bala when she was 27 and became an entrepreneur.
The idea to work on e-vehicles took root in 2007, when at a conference she heard a Toyota executive saying that the time for internal combustion engines was over.
She and Bala got thinking: if China could sell about 30 million e-vehicles (annually back then), then why not India?
Later, at the international mobility forum in Switzerland, she got a better perspective about e-engines. "I didn't just jump into this business; I did a lot of research and homework," says Annamalai.
In 2008, the couple sold their $1.8-million apartment in Singapore and moved to Coimbatore with their two school-going daughters to set up Ampere. (The name came from Andre-Marie Ampere who theorised the science of classical electromagnetism.)
Bala is an engineer but neither Annamalai nor he had tried to build or sell an e-vehicle before this. They were entering a tricky area.
Some big original equipment manufacturers had tried e-bikes, but those were not doing well. Ampere was foraying into a market where the technology, product and concept were all new.
Annamalai recollects that in 2010, when they were trying to raise money, financiers not only turned them away but also openly discouraged them. "They disqualified us," she says.
The couple slogged on, researching and trying to master the technology and the algorithms. Then, Forum Synergies and Spain's Axon Capital jointly invested around Rs 20 crore (Rs 200 million) in Ampere.
Next came Tata's investment. "This is not only an endorsement for the company but also for the entire electric vehicle industry," says Annamalai.
Expansion plans
The company now wants to mobilise around Rs 20 crore to scale up operations, hire talent and invest in research and development. The idea is to make the products 100 per cent indigenous, compared to 75 per cent currently.
The business case for e-vehicles looks strong: sales have grown at a fast clip, albeit from a low base.
According to the Society of Manufactures of Electrical Vehicles, sales increased 25 per cent to about 5,000 in the June-ended quarter from the year-ago quarter. "Government subsidies that benefit consumers directly triggered the sales," says Sohinder Gill, director (corporate affairs), SMEV.
Under its Faster Adoption and Manufacturing of Electric Vehicles scheme, the central government will also assist e-vehicle manufacturers with Rs 795 crore (Rs 7.95 billion) till 2020 to help them create infrastructure and R&D facilities.
But the success of e-vehicles will depend on their price tags. At the end of the day, the total cost of ownership should work out favourably for the buyer.
Ampere's e-cycle costs around Rs 23,500, and its e-scooter is priced at Rs 40,000-45,000. This is Rs 7,000-8,000 costlier than its competitors.
The company says this is because its two-wheelers come with a 60-volt battery and hence perform better, while others run on 40 volts. A dealer with a rival electric vehicle firm, however, argues that the performance is pretty much the same.
Ampere's customers are farmers and small-time businessmen who use these vehicles to transport their produce to the local markets.
Business to Business (B2B) customers, largely mill-owners in and around Coimbatore, also use its vehicles. Recently, corporations too have started using the vehicles to collect garbage.
User testimonials
P Venkatachalam, a farmer from Pollachi (45 km from Coimbatore) who bought an Ampere e-cycle about one-and-a-half years ago, says the experience was "satisfactory"; so, he's now bought Ampere's e-scooter called the V60. Venkatachalam drives the scooter for nearly 50 km in a day, and says it costs him around Rs 5 to charge the battery.
But given the long power cuts, isn't it difficult to regularly charge the battery? "Not really," Vankatachalam says, "Besides, the cycle's battery, which comes with a one-year guarantee, helps when the power goes off. A small tube light and a fan can run on it for a few hours."
Once charged, the e-cycle can run up to 45 km and the e-scooter to 60 km, he says. The vehicles can carry a load of up to 150 kg at a speed of 40 km per hour.
The battery needs 6 to 7 hours and about 1.8 units of power to be fully charged, says Kalimuthu, who is in charge of Ampere's dispatch department.
If maintained well, it can last for about three years during which it can be charged 750 times. Though a new battery costs Rs 15,000, in three years an e-vehicle proves to be still cheaper than a petrol or diesel version, says Kalimuthu.
Currently the company has 47 dealers across southern states and hopes to add another 20 in the next two months. It has a presence in Tamil Nadu, Kerala and Karnataka and will soon expend operations to Andhra Pradesh, and intends to operate only in South India.
Recently, it received its first export order for e-trolleys capable of carrying a load of 600 kg.
But it's still a while before e-vehicles become popular. Annamalai says that will happen only once volume picks up and bank financing to customers becomes easier. She says it will be another two to three years, at least, before the company will start making profits.

How skin cancer leapt after bikinis hit the beaches
How skin cancer leapt after bikinis hit the beaches: Rate went up 400% between the 1930s and 1960s
- Twenties swimwear exposed around 20 per cent of men and women's skin
- Skimpy outfits meant rise to 80 per cent for women and 89 per cent for men
- Modern-day bikinis expose 92 per cent of women's skin to harmful UV rays
- Cases of deadliest skin cancer rose from 1,800 in 1975 to 13,000 today

In the 1920s the amount of women's
skin exposed in swimwear was 20 per cent, but after Louis Reard invented
the bikini (pictured) that went to 80 per cent
The
bikini could be to blame for increasing rates of skin cancer,
researchers have concluded after analysing 100 years of beachwear.
Skimpy swimming costumes which became fashionable in the 1940s exposed more of the body to sunlight than ever before.
And with that greater exposure came a greater risk of melanoma, the most dangerous type of skin cancer.
The
study found that even taking into account increasingly early diagnosis
and wider reporting of cancer, changing tastes in clothing must have
played their part too.
The
team from New York University’s Langone Medical Centre said that in the
early 1900s tanned skin was frowned upon as being working class - and
porcelain skin was prized.
In
the 1920s men’s and women’s swimwear was very conservative and exposed
around 23 per cent and 18 per cent of the total skin surface area
respectively.
That
all changed in 1946 when French designer Louis Reard invented the
bikini which was quickly adopted in the US and then the rest of the
world.
But it increased skin exposure in women to 80 per cent as most of their body was open to the elements.
Men’s skin exposure also went up to 89 per cent as the swimming top was replaced by a bare chest and shorts.
The
study says: ‘People also began to enjoy more leisure time and to favour
swimwear and sportswear that progressively covered less skin.
‘Voices that raised concern about the dangers of UV exposure were largely ignored.’
The
study points to actresses like Bond Girl Ursula Andress as popularising
the tan which became associated with notions of ‘sexy, young, healthy,
and wealthy women’.
Yet from the 1930s to the 1960s US cancer rates in men and women increased by 69 per cent and 18 per cent.
Melanoma incidence went up by more than 300 per cent in men and 400 per cent in women.
The
study says: ‘This increase in melanoma incidence occurred in parallel
with changes in fashion, travel, and leisure that resulted in increased
skin and UV exposure.’
The authors add that in more recent years the rising use of tanning salons has increased the rise in melanoma rates further.
The study found that in recent years the bikini has become even more skimpy and even more damaging to women.
With
the emergence of ‘strapless tops and low-rise bottoms’ it now has a 92
per cent skin exposure, more than men who have stayed at 89 per cent.
The
researchers lay the blame for the popularity of tanning at the door of
women’s magazines and due to ‘celebrity promotion’ during the last
century.

Modern designs have increased the
amount of skin exposed to nearly 92 per cent. Cases of malignant
melanoma, the deadliest form of skin cancer, have risen to 13,000 a year
from 1,800 in 1975
In
Britain figures from Cancer Research UK show that more than 13,000
people a year develop malignant melanoma - the most deadly type of skin
cancer.
The total is expected to surge to 20,000 a year by 2027. In 1975 the figure was just 1,800.
The shocking rise has been blamed on the legacy of sunshine package holidays which became popular in the 1960s.
Many of the patients being diagnosed today suffered cancer-causing sunburn in their youth, experts have said.
Adding
to the problem was in the 1960s - often dubbed the ‘Bronze Age’ - few
people were aware of the dangers of sunbathing in the way they are now,
meaning they unknowingly caused themselves long term damage.
Since
then the majority have shied away from a deep tan popularised by the
likes of George Hamilton including many celebrities, for whom a healthy
glow is considered enough.
Among
those who were have been treated for skin cancer in the UK is Tiny De
Vries, a 63-year-old businesswoman and author from Bath.
She regularly went bright red after tanning all day on cheap package holidays to Spain during the 1960s and 70s.
In
an interview she has said: ‘I’m far more cautious these days, but 40
years ago no one knew any better. How I wished I’d been more aware of
the dangers before it was too late.’
The History Man, Saumur, France, 9 months ago
This
is a correlation but not necessarily a causal link.
Two other things
that have changed since the 1920s is that people as a whole have far
more leisure time and actually take holidays in the sun and on the
beach.
The average worker in the 1930s couldn't afford to do more than
go to Margate or Weston on the train for a weekend.
The other thing
that has changed is the erosion of the ozone layer, not just from CFCs
but from all the other pollutants and chemicals we have increasingly
poured into the atmosphere in the second half of the 20th century.
This
has allowed far more UV to pass through to affect people, animals and
plants, and the ozone layer is only now showing some very small signs of
recovery. Many agricultural workers always used to do the harvest
stripped to the waist but is there evidence of their rates of skin
cancer?

Cheap 3D printed robotic arm controlled by the mind

For Easton LaChappelle, a 19-year-old from Colorado in the United States (U.S.), the difficulty with robotics has never been the technology itself - something he says he managed to master in a matter of months from his bedroom in his parent's house - but the cost.
The technology used by most robotic arms and hands on the market - and many more of those in development - typically comes with large overheads.
In the last five years, though, learning almost exclusively online in forums and emails, LaChappelle has managed to synthesize a series of robotic hands that could change industries and lives - and most of which cost just a few hundred dollars.
While other developments in countries like Austria and Argentina have pushed the boundaries of prosthetic offerings, helping those missing limbs to start to regain use of them with robotics, LaChappelle has done so using 3D printing.
And he's made one that he says can read your mind. It's called Anthromod.
"This reads right about 10 channels of the brain, so it kind of works kind of like a muscle sensor in that it picks up small electric discharges and turns that into something you can actually read within software, and then we actually track patterns and try and convert that into movement. So with this I'm actually able to change grips, grip patterns, based on facial gestures, and then use the raw actual brainwaves and focus to actually close the hand or open the clamp or hand," he told Reuters Television.
One of the most important aspects of the Anthromod design is the way in which it's controlled by the software, which LaChappelle says is different from the types of control that exist in other robotic platforms.
While it's the hand itself that moves, as more advanced controls are created it's the software that's doing the heavy lifting, using algorithms that make the arm easier to use.
"A good example is we actually had an amputee use the wireless brainwave headset to control a hand, and he was able to fluently control the robotic hand in right around about 10 minutes, so the learning curve is hardly a learning curve any more," he said.
The arms themselves might not look polished and ready for the shop floor - but LaChappelle sees them as cutting edge.
His robotic arms are all prototypes, each fulfilling a different need according to their design, with some using a wireless brainwave headset, designed more for prosthetic use. Another of his tele-robotic controlled hands was created with dangerous environments in mind, where human-like robots could be sent to allow people to monitor situations and intervene from afar.
"I really tried to make this as human-like as possible - this is probably about my fifth generation of the full robotic arm, and this is controlled using a full tele-robotic system, so there's actually a glove that you wear that tracks your hand movements, accelerometers to track your wrist and elbow, and then an IMU sensor as well to track your bicep rotation as well as your shoulder movement, and that gets all translated wirelessly to the robotic arm where it will copy what you do," he said.
One of the most impressive aspects of the arm is not the hardware itself, or even the software that controls it - but the fact that it can be 3D printed for a fraction of the cost of modern prosthetics.
This allows him to make complex internal structures to the designs which would otherwise be impossible, using not just any 3D printer, but precisely the kind many expect people to have at home in the near future.
"So 3D printing allows you to create something that's human-like, something that's extremely customized, again for a very low cost, which for certain applications such as prosthetics, is a really big part of it," he told Reuters.
"The full robotic arm is actually open source, and so people are now actually able to take this, reproduce it, and adapt it for different situations, applications, and really see what you can do with it," he added.
The Anthromod itself cost only about 600 dollars to make, LaChappelle said.
His work is documented in the videos he made at home, showing his handiwork - all part of his effort at making the invention open source - which means anyone can take his technology and customize and build on it.
The idea, he said, is not to create something that can solve problems for those with prostheses and other needs for robotic arms like the ones he's invented - but rather to create a platform that people around the world can use to customize their own versions of to suit their needs.
"A big reason we designed this on the consumer level is because we made this open source, we want someone that has a 3D printer, or very little printing experience, to be able to replicate this, to be able to use this for new applications, to be able to adapt it into new situations, so it's really exciting to see what people will start doing with something like this," he said.
"For the actual arm, we designed everything to be modular, meaning all the joints can actually interchange, and there's a universal bolt pattern. So you can now create something human-like, or you can create a big 20 degree freedom arm for complex filming or even low cost automations. So we really want to make a robotics platform, not so much just a robotics hand from this," he added.
LaChappelle hopes his efforts will contribute to developments in bomb defusal robots, heavy equipment and heavy industrial automation robotic arms, as well as exoskeletons.
