Scientists invent silk food wrap that's biodegradable and could replace plastic cling film
Bananas and strawberries kept at room temperature for more than a week did not go off after they were coated with a near-invisible film made from silk
Ian Johnston
Scientists have invented a cling film-like food wrap made from silk that can preserve fruit for more than a week, as a natural, biodegradable alternative to plastic.
International concern has been growing about plastic waste, particularly the amount that gets into the sea. One estimate is that by 2050 there will be more plastic than fish in the world's oceans.
Doctors have also warned that containers made from certain kinds of plastic could be harmful to health.
Now a team of biomedical engineers at Tufts University in the US have developed a technique that enables food to be coated with an almost invisible layer of fibroin, a protein found in silk, which helps make it one of nature's toughest materials.
The lead researcher, Professor Fiorenzo Omenetto, told The Independent that the world should probably move "towards processes that are more efficient and more naturally derived" and develop materials that "are closer to the things that surround us, rather than having more man-made, processed materials ... for the general well-being of our planet".
"It's a wise way of thinking about how we manage the resources of our planet, to maybe use renewable systems as opposed to non-renewable systems," he said.
"The pervasiveness of plastic and all the inorganic chemicals that leach out, albeit at very slow rates, can affect us in many ways."
When asked what the chances were that silk-derived products would replace plastics, Professor Omenetto said: "That's our dream."
However he said the use of plastic was widespread and "incredibly cost effective" so it might take some time to convince people to change.
The same team previously made a silk cup that could be used, at least once, for coffee as a possible replacement for plasticlined cardboard cups.
In a paper in the journal Scientific Reports, they described how strawberries and bananas could be preserved for a week or more.
The fruit is coated by dipping it in a liquid containing a tiny amount of fibroin, but the wrap could also be applied with a spray. The silk is produced naturally by worms of moths.
Strawberries left for seven days at room temperature became discoloured and went soft, but those coated with the silk protein stayed juicy and firm.

LEARNING FROM THE LAZARUS EFFECT
Most clinical trials for cancer drugs are failures. But for a handful of patients, a drug proves to be nearly a cure. What can science learn from these “exceptional responders”?
For years, Grace Silva had experienced odd episodes with her throat — bouts of swelling and radiating pain that seemed to resolve with antibiotics — but her doctors couldn’t explain what was wrong. Finally, after a flare-up in the summer of 2010, Grace was referred to a specialist, an ear doctor who felt something amiss on the left side of her throat: a lump. The Silva family agreed that it was time to get Grace, then 54, to a thyroid specialist. Grace’s daughter Melanie tracked down the name of one at Brigham and Women’s Hospital, a 90-minute drive from Grace’s brown clapboard split-level near New Bedford, Mass. In September 2010, the specialist delivered the diagnosis: anaplastic thyroid cancer. It was bad, he warned her, and she would need surgery. Grace’s other daughter, Karrie, was marrying in a few weeks. “Can’t it wait?” Grace asked. It could not. “And whatever you do,” the specialist said, “please don’t look it up on the Internet.”

CAN ADDICTION TO SMARTPHONES TRIGGER ADHD?
We measured inattentiveness and hyperactivity by asking participants to identify how frequently they had experienced 18 symptoms of ADHD over each of the two weeks. These items were based on the criteria for diagnosing ADHD in adults as specified by the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders. The results were clear: More frequent phone interruptions made people less attentive and more hyperactive. These findings should concern us. Smartphones are the fastest-selling electronic gadget in history—in the 22 seconds it took to type this sentence, 1,000 smartphones were shipped to their new owners. Even if one of those 1,000 users became more likely to make a careless mistake, ignore a friend in the middle of a conversation or space out during a meeting, smartphones could be harming the productivity, relationships and well-being of millions.
As with all disorders, symptoms of ADHD form a continuum, from the normal to the pathological. Our findings suggest that our incessant digital stimulation is contributing to an increasingly problematic deficit of attention in modern society.
So consider silencing your phone, even when you are not in the movie theater. Your brain will thank you.

TEXTO
Brazil has declared an end to its public health emergency over the Zika virus, 18 months after a surge in cases drew headlines around the world.
The mosquito-borne virus was not considered a major health threat until the 2015 outbreak revealed that Zika can lead to severe birth defects. One of those defects, microcephaly, causes babies to be born with skulls much smaller than expected.
Photos of babies with the defect spread panic around the globe as the virus was reported in dozens of countries. Many would-be travellers cancelled their trips to Zika-infected places. The concern spread even more widely when health officials said it could also be transmitted through sexual contact with an infected person.
The health scare came just as Brazil, the epicentre of the outbreak, was preparing to host the 2016 Olympics, fuelling concerns the Games could help spread the virus. One athlete, a Spanish wind surfer, said she got Zika while training in Brazil ahead of the Games.
In response to the outbreak, Brazil launched a mosquito-eradication campaign. The health ministry said those efforts have helped to dramatically reduce cases of Zika. Between January and mid-April, 95% fewer cases were recorded than during the same period last year. The incidence of microcephaly has fallen as well.
The World Health Organization (WHO) lifted its own international emergency in November, even while saying the virus remained a threat.
“The end of the emergency doesn’t mean the end of surveillance or assistance” to affected families, said Adeilson Cavalcante, the secretary for health surveillance at Brazil’s health ministry. “The health ministry and other organisations involved in this area will maintain a policy of fighting Zika, dengue and chikungunya.”
All three diseases are carried by the Aedes aegypti mosquito.
But the WHO has warned that Zika is “here to stay,” even when cases of it fall off, and that fighting the disease will be an ongoing battle.
