Eat: A Diet to Ward Off Breast Cancer

Eating substantial amounts of fruits and vegetables may lower the risk for breast cancer, a new study has found, and some kinds may be more effective than others.

Researchers used well-validated nutrition questionnaires to examine the association of dietwith the risk of invasive breast cancer in 182,145 women. They followed them with periodic examinations for an average of 24 years, during which there were 10,911 cases of invasive breast cancer. The study is in the International Journal of Cancer.

After controlling for many health, diet and behavioral variables, the scientists found that compared with having less than two and a half servings (about one cup) of fruits and vegetables a day, having five and a half servings or more was associated with an 11 percent lower breast cancer risk. The effect was especially significant with the most aggressive types of breast cancer.

''There are few potentially modifiable risk factors for breast cancer,'' said the lead author, Maryam S. Farvid, a research scientist at Harvard, ''and eating more fruits and vegetables would be a simple way to help lower the risk.''

The researchers found that cruciferous vegetables like cauliflower, brussels sprouts and kale were especially strongly associated with reduced risk, as were yellow or orange vegetables including carrots, winter squash, yams and sweet potatoes.

More than 100 South African gold miners treated for smoke inhalation

JOHANNESBURG (Reuters) – Hundreds of South African gold mine workers were rescued and over 100 treated for smoke inhalation after an underground fire, the National Union of Mineworkers (NUM) said on Thursday

Safety is a huge issue in South Africa’s dangerous deep-level mines and a focus for investors. A spate of deaths at SibanyeStillwater’s gold operations, including a seismic event that killed seven miners in early May, has highlighted the risks.

In the latest incident, more than 600 miners were initially trapped after a fire broke out at a mine east of Johannesburg operated by unlisted Gold One, NUM said.

This comes almost two weeks after five miners died in an underground fire at a South African copper mine operated by unlisted Palabora Mining Company in Limpopo

Company officials could not immediately be reached for comment.

“As the NUM, we vehemently condemn this kind of incident as it is becoming a trend”, the union said in a statement.

Robotic Cars

The year is 2020, and it's 7;45 on a rainy Monday morning, and you are in your car on your way to work. You turn right, and you turn left. A few minutes later, you stop at a traffic light. When the light turns green and there are no other cars in the intersection, you continue on your way. Ten minutes later you get to work and stop reading the morning paper. Then, you get out of your car and you say, “Thank you!”, Your car replies, “You're welcome!”. This possible future may sound unreal, but in fact many car companies are already testing robotic cars, or driverless cars, on the roads today, although the cars don't speak very much yet.

In the 1980s, Germany and the United States tested the first driverless cars, and by 2020 companies such as Volvo, GM, Nissan and BMW plan to sell driverless cars. Driverless cars are not really 'driverless' - the drivers are computers that use radar, computer maps and other modem technology. They offer many advantages. Perhaps the most important of these is fewer deaths caused by road accidents. For example, in 1968 more than 53.000 people lost their lives in car accidents in the USA. This number has fallen to less than 33.000 but it's still à high number. In addition, people will spend less time stuck in traffic jams and there will be no need for people to have a driving license. One of the major disadvantages of this new technology, however, is the cost. It's not free. U$5.000 to U$10.000 is added to the price of the new car. Nevertheless, at some time in your life, you will probably be sitting in a robotic, .driverless car on your way to work or school. The future is almost here. Are you ready for it?

Research and advances in medicine:
Curious minds work to solve problems

Medical science has made remarkable strides over roughly the past 75 years, beating back many once life-threatening illnesses and helping to extend the life expectancy of a child born in 2016 to nearly 79 years. By all measures, the pace of change appears to be accelerating.

Dr. Lynell Klassen, a researcher and professor of internal medicine at the University of Nebraska Medical Center, tells students they’ve got a lot ahead of them. “This is really an exciting time to be in medicine. All of the possibilities, the potential for understanding and altering our life functionality is greater than it’s ever been in the past,” he said.

- A look at the past

In the 1930s and 1940s, hospitals were full of young people sick and dying of routine infections, from tuberculosis to appendicitis. The group of antimicrobials, which includes antibiotics such as penicillin, changed that – literally overnight. Vaccines ended epidemics of childhood killers such as polio, diphtheria and pertussis, and provided protection against those such as measles and mumps.

Imaging technologies of increasing power and precision – X-rays, CT, MRI, PET scans, portable ultrasound, 3-D mammography, endoscopies with pill-sized devices, have given us the ability to peer into the body, in some instances to the cellular level.

- A peek into the future

The Human Genome Project gave us the blueprints; the next step involves putting that knowledge to use in medicine. The first gene therapy for an inherited disease, a form of blindness, has recently been approved. In the computing realm, scientists are envisioning the future use of artificial intelligence in medicine, as well as technologies such as augmented reality and virtual reality.

Meet the 'homeless man' who flies the world first class
[1] For the last year and a half, Ben Schlappig has been
essentially homeless. The 25-year-old American has ___________
fixed address, ___________ the keys to his own front door. Why
bother paying rent, he figured, when a bed was only ever a
[5] first class ticket away?
Schlappig is a "Hobbyist," as those in the game call it - a
professional traveler with an almost obsessive attention to
fine print, who uses a mixture of frequent flyer miles and
credit card reward points, to zoom around the globe for a
[10] fraction of the cost.
Since he first started racking up air miles a little over a
decade ago – yes, he was just 14 when he started this –
Schlappig says he's never flown economy on an international
flight.
