Exercise: The cellular fountain of youth

Tuesday, 04 April 2017 02:35

HIGH-INTENSITY exercise may help older adults reverse certain aspects of the “cellular” aging process, a new study suggests.
It's no secret that regular exercise is healthy for young and old alike. But researchers said the new findings point to particular benefits from "high-intensity interval training" for older adults.
That's the type of workout that combines brief bursts of vigorous exercise with periods of moderate activity: A person might, for example, go all-out on a stationary bike for a few minutes, ease up for the next few, and then start again.

Tests may bring new wave of cancer detection

Monday, 03 April 2017 03:58

DETECTING cancer may be getting easier.New kinds of tests that promise to be less invasive are beginning to exit the lab and enter the market -- with more under development.
By using blood, urine, and saliva, researchers hope these new tests may reduce the need for often painful, risky biopsies, a type of surgery to remove suspicious tissue for study.
The hunt for new ways to detect cancer has heated up in the past few years, as has investment in new tools and tests. In January, a San Francisco-based startup called Grail pledged to raise $1 billion to develop a blood test for early detection.

Can a fertility app stop pregnancy?

Monday, 13 February 2017 18:00

SEXUAL health experts say more research is needed into the effectiveness of fertility tracking apps in preventing pregnancy.The warning comes after the first such app - Natural Cycles - was given an official approval as a method of contraception. In 2015 a clinical study showed that the app was as effective as the pill.

The app works by getting women to enter their body temperatures, ovulation test results and date of menstruation. An algorithm (a set of rules to help solve a problem, run by computer software) then determines whether a woman is fertile on that day.

This should help her make a decision about having unprotected sex. But while sexual experts agreed fertility awareness apps have great potential to broaden contraception choice - three organisations warned on Thursday that being classed as a medical device doesn't guarantee the app will effectively prevent pregnancy.

Vaccines for three deadly viruses fast-tracked

Sunday, 22 January 2017 18:00

Scientists have named three relatively little-known diseases they think could cause the next global health emergency.A coalition of governments and charities has committed $460m to speed up vaccine development for Mers, Lassa fever and Nipah virus. They are asking funders at the World Economic Forum Davos for another $500m.

The Coalition for Epidemic Preparedness Innovations (Cepi) aims to have two new experimental vaccines ready for each disease within five years. New vaccines usually take about a decade to develop and cost hundreds of millions of dollars.The Ebola outbreak in West Africa, closely followed by the Zika epidemic in Latin America, exposed just how "tragically unprepared" the world is for new outbreaks.

Processed meat could be bad for asthma

Monday, 09 January 2017 18:00

EATING processed meat might make asthma symptoms worse, say researchers.

Consuming more than four portions a week is a risk, suggests the study of nearly 1,000 French people, published in the journal Thorax. The researchers believe it could be a preservative called nitrite used in meats such as sausages, salami and ham that aggravates the airways.

But experts say the link has not been proved and more investigations are needed. Rather than worry about one type of food, people should be eating a healthy and varied diet, they advise. Processed meat has already been linked with cancer. Experts say people should eat no more than 70g a day of red and processed meat for good health.

Obesity boom fuelling rise in malnutrition

Tuesday, 13 December 2016 18:00

MALNUTRITION is sweeping the world, fuelled by obesity as well as starvation, new research has suggested. The 2016 Global Nutrition Report said 44% of countries were now experiencing "very serious levels" of both under-nutrition and obesity.

It means one in three people suffers from malnutrition in some form, according to the study of 129 countries. Being malnourished is "the new normal", the report's authors said. Malnutrition has traditionally been associated with children who are starving, have stunted growth and are prone to infection.

These are still major problems, but progress has been made in this area. The report's authors instead highlighted the "staggering global challenge" posed by rising obesity. The increase is happening in every region of the world and in nearly every country, they said.

Flavoured e-cigarettes may entice teens to smoke

Sunday, 13 November 2016 18:00

FRUIT- or candy-flavoured electronic cigarettes may entice teens to start smoking tobacco, a new study suggests.Using data from the 2014 National Youth Tobacco Survey, researchers at the University of Missouri-Kansas City found that among middle school and high school students who had never smoked, 58 percent who used flavored e-cigarettes said they intended to start smoking tobacco cigarettes.

"Due to a proliferation of e-cigarette flavors on the market, flavored e-cigarette use among youth in the U.S. has increased significantly," study author Hongying Dai said. She's an associate professor of health services and outcomes at Children's Mercy Hospital in Kansas City.

Acne: New research could lead to new treatments

Tuesday, 01 November 2016 19:00

IN a finding that could lead to new treatments for acne, scientists say they've discovered a previously unrecognized way in which bacteria trigger inflammation in the skin.The skin is the body's first line of defense against invading germs. But it's also constantly awash in bacteria of all kinds -- and usually puts up no fight.

"It's a big puzzle as to why we tolerate all these bacteria on our skin," said lead researcher Dr. Richard Gallo, interim chair of dermatology at the University of California, San Diego. "Usually, we walk around at peace with them," Gallo pointed out. "But at certain times, that detente breaks down and you get an infection."In its study, Gallo's team focused on the Propionibacterium acnes bacteria. As the name suggests, the bacteria can contribute to acne -- as well as certain other infections.
