Antioxidant Effects differ by Leaf Color
March 27, 2015 01:47 PM - University of the Basque Country
Lettuce, one of the indispensable vegetables in the Mediterranean diet, is a food that greatly benefits health, mainly because it is rich in antioxidants. But not all lettuce varieties have the same antioxidant effect. According to a study led by the researcher Usue Pérez-López of the Department of Plant Biology and Ecology of the UPV/EHU's Faculty of Science and Technology, the colour of the leaves of these vegetables determines the speed at which their compounds act. So lettuces with green leaves have antioxidants that react more slowly while red-leaf ones have a faster effect. The results of this study have been set out in a paper "Phenolic Composition and Related Antioxidant Properties in Differently Coloured Lettuces: A Study by Electron Paramagnetic Resonance (EPR) Kinetics" recently published by the ‘Journal of Agricultural and Food Chemistry'.
United Nations warns on pesticides
March 23, 2015 09:55 AM - EurActiv
The UN's International Agency for Research on Cancer (IARC) said Friday (20 March) that three pesticides, including the popular weed killer Roundup, were "probably" carcinogenic and two others, which have already been outlawed or restricted, were "possibly" so.
IARC classified the herbicide glyphosate – the active ingredient in Roundup – and the insecticides malathion and diazinon as "probably carcinogenic" on the basis of "limited evidence" of cancer among humans.
Tobacco smoke impacts the unborn too
March 8, 2015 08:55 AM - THE ENDOCRINE SOCIETY via EurekAlert.
A fetus exposed to tobacco smoke may be at increased risk for diabetes in adulthood, a new study of adult daughters finds. The results will be presented in a poster Saturday, March 7, at ENDO 2015, the annual meeting of the Endocrine Society in San Diego.
Women whose parents smoked during pregnancy had increased risk of diabetes mellitus independent of known risk factors, adding to the evidence that prenatal environmental chemical exposures can contribute to adult diabetes mellitus.

The good role fat cells play in protecting us from disease
January 2, 2015 09:21 AM - UNIVERSITY OF CALIFORNIA - SAN DIEGO, via EurekAlert.
When it comes to skin infections, a healthy and robust immune response may depend greatly upon what lies beneath. In a new paper published in the January 2, 2015 issue of Science, researchers at the University of California, San Diego School of Medicine report the surprising discovery that fat cells below the skin help protect us from bacteria.
Richard Gallo, MD, PhD, professor and chief of dermatology at UC San Diego School of Medicine, and colleagues have uncovered a previously unknown role for dermal fat cells, known as adipocytes: They produce antimicrobial peptides that help fend off invading bacteria and other pathogens.
New study analyzes sound sensitivity of marine invertebrates
December 22, 2014 02:57 PM - Woods Hole Oceanographic Institution
Noise pollution in the ocean is increasingly recognized as harmful to marine mammals, affecting their ability to communicate, find mates, and hunt for food. But what impact does noise have on invertebrates -- a critical segment of the food web? Very few studies have attempted to answer that question. The harder question to answer might be 'How do you measure hearing in ocean invertebrates'? A new study by researchers at Woods Hole Oceanographic Institution and their colleagues examined behavioral responses to sound by cuttlefish, a type of shell-less mollusk related to squid and octopi. The study is the first to identify the acoustic range and minimum sound sensitivity in these animals. Their findings, published in the Journal of Experimental Biology, can help decision makers and environmental managers better understand the impacts of noise in the ocean.
Drugs released in environment affect plant growth
December 5, 2014 02:04 PM - University of Exeter
The drugs we release into the environment are likely to have a significant impact on plant growth, finds a new study led by the University of Exeter Medical School and Plymouth University. By assessing the impacts of a range of non-steroidal anti-inflammatory drugs, the research has shown that the growth of edible crops can be affected by these chemicals – even at the very low concentrations found in the environment.
China gets serious about reducing smoking
December 2, 2014 02:21 PM -
In 2009, China's estimated 300 million smokers consumed a staggering 2.3 trillion cigarettes: more than the number smoked in the next four top tobacco-consuming countries—Indonesia, Japan, Russia, and the United States—combined. The health toll is enormous as well: Tobacco causes roughly 1 million deaths in China each year, including 100,000 fatalities blamed on secondhand smoke, according to the World Health Organization (WHO). If tobacco use is not curtailed, WHO warns, China’s death toll could rise to 3 million each year by 2050.
The nation’s capital, Beijing, is taking that chilling message to heart. On 28 November, the Beijing Municipal Government adopted a ban on smoking in all indoor public places—"with no loopholes and no exemptions," crowed Bernhard Schwartländer, the WHO representative in China, in a press release. The new law will take effect on 1 June 2015.
Is Premium Milk on the Horizon?
December 1, 2014 09:41 AM - Leon Kaye, Triple Pundit
Could premium milk be the greatest coup for beverage companies since bottled water? Coca-Cola apparently thinks so. Like its competitors within the beverage industry, the company is trying to find new ways to boost profits since their flagship products, fizzy drinks, have long been suffering from flat sales. While more consumers avoid both sugary and diet sodas and hipsters find alternatives from cold brewed bottled coffee to kombucha, Coca-Cola’s shareholders want increased sales. Premium milk could be the answer for Coke. Coca-Cola is a major investor in Fairlife, which promises to transform the dairy industry by providing “more vroom for your milk.” Starting with the marketing, this is not your parents’ or grandparents’ dairy: instead of pastoral scenes of farmers and cows, the ads are a composite of Alicia Silverstone Aerosmith videos, Marilyn Monroe’s iconic Seven Year Itch photo and a certain scene in Something about Mary. So what is all the fuss about? After all, it is just milk, right? Not according to Coca-Cola.
The link between Omega-3 fatty acid and stopping smoking
November 30, 2014 08:36 AM - NoCamels Team, NoCamels
Think you’ve tried everything to quit smoking, but just couldn’t do it? Then you’ll want to read on. According to a new study, taking omega-3 supplements reduces craving for nicotine and even reduces the number of cigarettes you smoke a day.
“The substances and medications used currently to help people reduce and quit smoking are not very effective and cause adverse effects that are not easy to cope with. The findings of this study indicated that omega-3, an inexpensive and easily available dietary supplement with almost no side effects, reduces smoking significantly,” said Dr. Sharon Rabinovitz Shenkar, head of the addictions program at the University of Haifa.
