Johnny: Are there any memories you&`&d like to permanently remove from your head? (科学家或已知道抹除记忆的方法)
Or what if you could alter unpleasant memories so they&`&re no longer upsetting? Or create entirely new memories of events that never occurred?
It sounds like the stuff of science fiction, but according to a new documentary that premiered in the US recently, scientists have discovered how to do just that - and more.
Iris:
"Memory Hackers," from PBS&`&s NOVA documentary strand, looks at cutting edge research into the nature of memory, and how it might be manipulated for mankind&`&s benefit.
"For much of human history, memory has been seen as a tape recorder that faithfully registers information and replays it intact," say the film&`&s makers.
"But now, researchers are discovering that memory is far more malleable, always being written and rewritten, not just by us but by others. We are discovering the precise mechanisms that can explain and even control our memories."
Whitney:
Among the documentary&`&s subjects is Jake Hausler, a 12-year-old boy from St. Louis who can remember just about every single thing he has experienced since the age of 8.
Jake is the youngest ever person to be diagnosed with Highly Superior Autobiographical Memory, which makes it difficult for him to distinguish between trivial and important events from his past.
"Forgetting is probably one of the most important things that brains will do," says Andre Fenton, a prominent neuroscientist who is currently working on a technique to erase painful memories. "We understand only the tip of the iceberg when it comes to human memory."

As the battle against the post-festive bulge1 rages on, many of us are seeking out any extra help we can get with New Year&`&s resolutions to lose weight.(可以帮你抑制食欲的香水)
But can a fragrance2 really help to curb3 your appetite and speed you towards your weight loss goals?
Prends Moi by Velds is the UK&`&s first fragrance to aid weight loss and promises to induce the release of B-endorphins in the skin - triggering a sense of wellbeing, thus reducing the urge to overeat.
Costing £15, its makers4 claim the fragrance is designed to &`&slim with pleasure&`& and is based on &`&aromatherapeutic&`& and &`&neurocosmetic&`& research.
Developed by the French perfume house Robertet, its zesty5 scent6 comes from a blend of bergamot, mandarin7, lilac and ylang ylang.
Iris:
It also contains active ingredients including Betaphroline, a wild indigo8 seed extract, which when it comes in to contact with keratinocytes (cells found in the outer layer of the skin) will induce the release of B-endorphins present.
This sends a &`&pleasure message&`& to the brain and the resulting sensation of wellbeing and increased feeling of contentment will supposedly stop you reaching for the biscuit tin to get a feelgood fix.
In addition, it contains a &`&Slimming Complex&`& formulated9 with caffeine, carnitine and spirulina extract, which activates10 the two key enzymes11 directly involved in lipolysis (fat degradation).
The fragrance&`&s claims appear to be backed up by science.
Whitney:
A trial study by BIO-EC, the Centre of Biological Research and Cutaneous Experimentation12, appears to back up the claims made my Prends Moi.
They carried out a study of women aged13 between 18 and 70 years of age, who were not on a diet, found that 75 per cent felt the perfume limited the need to snack and 73 per cent felt a feeling of pleasure.
More than 80 per cent experienced a feeling of comfort after application and 70 per cent felt it had an impact on their eating behaviour.
To get the full effect, Prends Moi advises that you generously spritz in the morning, as you would do with any perfume, and throughout the day when the need for snacking arises.

If you&`&re a sucker for sneakers and have a wardrobe full of different designs, this new invention could save you money and space.(轻松变换图案和颜色的鞋子)
The &`&ShiftWear&`& range has flexible colour e-ink displays so wearers can change the pattern and colour of their shoe at the touch of a button.
They are designed to work with a dedicated1 app offering a &`&wardrobe&`& of design options and the footwear will even be able to display animations2.
Designer David Coelho, based in New York, is raising money on Indiegogo to make the shoes a reality.
The campaign claims the ShiftWear shoes are &`&the most adaptable3 shoes you&`&ll ever own, customised straight from your smartphone.&`&
Available as high, medium and low tops, the shoes will include e-ink panels, using a similar technology to that seen in Amazon&`&s Kindle4 e-reader, but in colour.
Iris:
Users will be able to use an accompanying app to choose designs for the shoes that will be displayed on the flexible screens.
&`&In addition to static designs and images, ShiftWear shoes can also display animations,&`& the start-up added.
&`&However, if your design is static, the sneaker will consume no power and your design will stay that way till you change it.&`&
The trainers will have up to 30 days battery life if displaying a static image.

If the Internet is important to you, you may need to reconsider where you live based on the results of a new report from the International Telecommunication Union, which has revealed the countries with the best Internet connections in the world.
Whitney:
According to the study, which took into account Internet speed and the percentage of people who have access to a connection, we all need to move to South Korea if we want to be better connected – it just topped the list for the second time in a row. Other developed countries, however, didn’t fare as well as you might expect.
The US, for example, is 15th on the list, behind the UK, Australia, and Japan. Although to be fair, it was an improvement on its position of 16th in the last report, which came out in 2010. Meanwhile, China placed an underwhelming 82nd, falling behind Mauritius, Brazil, and Dominica.
And Chad had the worse Internet connection, with a score of just 1.17. In fact, Sub-Saharan African countries took out the 23 bottom spots on the list, which isn’t entirely surprising given previous instability in parts of the region.
