London (CNN)After President Donald Trump called him “two-faced,” Canada’s Prime Minister, Justin Trudeau, admitted Wednesday that he and other world leaders were talking about the US President when they were caught on camera at a Buckingham Palace event the night before.
“While each gram of regular tobacco contains 16 milligrams of nicotine, the newly edited version contains only 0.04 percent,” said the study’s lead author Felix Stehle.
“No one in the world has ever managed to reduce nicotine to this level,” he added.
The researchers published their study in the Plant Biotechnology journal.
The tobacco plant is not used to make cigarettes only, but also as a living sample in main research fields.
The researchers explained they used gene cutting to alter the genetic characteristics of this plant. They omitted six genes that play a major role in nicotine production. Although the plant regrouped these genes, it did so in a wrong way, which stopped the production of nicotine. The researchers assured that this process can be used with almost all types of tobacco.
Nicotine is the substance that leads to smoking addiction, in addition to the 4800 substances found in cigarettes, of which 70 substances cause cancer, or suspected to develop cancer.
(CNN)Valerie Harper, who achieved fame as Rhoda on the classic sitcom “The Mary Tyler Moore Show” and continued as the character in a popular spin-off series, has died after a long battle with cancer, her daughter Cristina Cacciotti and family friend Deanna Buskey confirmed to CNN.
Scientists say they have discovered why some vegetables – including cabbage, broccoli and kale – can reduce the risk of bowel cancers.
That cruciferous veg is good for the gut has never been in doubt but a detailed explanation has been elusive.
The team at the Francis Crick Institute found anti-cancer chemicals were produced as the vegetables were digested.
Cancer Research UK said there were plenty of reasons to eat more veg.
The work focused on how vegetables alter the lining of the intestines, by studying mice and miniature bowels growing in the lab.
Like the skin, the surface of the bowels is constantly being regenerated in a process that takes four to five days.
But this constant renewal needs to be tightly controlled, otherwise it could lead to cancer or gut inflammation.
And the work, published in the journal Immunity, showed chemicals in cruciferous vegetables were vital.
The researchers investigated a chemical called indole-3-carbinol, which is produced by chewing such vegetables.
“Make sure they’re not overcooked, no soggy broccoli,” said researcher Dr Gitta Stockinger.
The chemical is modified by stomach acid as it continues its journey through the digestive system.
In the lower bowel, it can change the behaviour of stem cells, which regenerate the bowel lining, and of immune cells that control inflammation.
The study showed diets high in indole-3-carbinol protected the mice from cancer, even those whose genes put them at very high risk of the disease.
Without the protective diet, the gut cells divided uncontrollably.
Dr Stockinger added: “Even when the mice started developing tumours and we switched them to the appropriate diet, it halted tumour progression.”
Signs of bowel cancer include persistent:
Dr Stockinger said the findings were a “cause for optimism”.
She has reduced the amount of meat she eats and now consumes a lot more vegetables.
She told the BBC: “A lot of dietary advice we’re getting changes periodically – it is very confusing and not clear cut what the causes and consequences are.
“Just telling me it’s good for me without a reason will not make me eat it.
“With this study, we have the molecular mechanisms about how this system works.”
Prof Tim Key, from Cancer Research UK, said: “This study in mice suggests that it’s not just the fibre contained in vegetables like broccoli and cabbage that help reduce the risk of bowel cancer, but also molecules found in these vegetables too.
“Further studies will help find out whether the molecules in these vegetables have the same effect in people, but in the meantime there are already plenty of good reasons to eat more vegetables.”

Cancer morbidity in Shanghai has risen 141 percent in the past four decades, according to the latest data released by local health authorities.
But the rate of deaths among cancer patients dropped by 42 percent in this period due to better screening, registration and monitoring.
This week is the city’s Cancer Prevention and Treatment Week with various events promoting cancer prevention.
An opening ceremony was held on Sunday in Changning District which included a walking race.
Data shows that almost 30 percent of local adults do not engage in physical activities and more than 30 percent are overweight. Nearly 10 percent suffer obesity.
Research shows that 40 percent of the causes of cancer in China are bad habits such as lack of exercise, poor diet, smoking and drinking.
Residents who want to know more about cancer and related activities can find information on the WeChat accounts of the local heath commission and center for disease control and prevention.
By 2015, cancer was the second major cause of death in Shanghai.
More than 70,000 people in Shanghai were diagnosed with cancer and nearly 40,000 died as a result in 2015.
