Human sweat conveys our emotional state!
April 16, 2015 06:50 AM - ASSOCIATION FOR PSYCHOLOGICAL SCIENCE via EurekAlert.
Humans may be able to communicate positive emotions like happiness through the smell of our sweat, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research indicates that we produce chemical compounds, or chemosignals, when we experience happiness that are detectable by others who smell our sweat.
While previous research has shown that negative emotions related to fear and disgust are communicated via detectable regularities in the chemical composition of sweat, few studies have examined whether the same communicative function holds for positive emotions.
How California distributes scarce water
April 15, 2015 08:09 AM - Dan Charles, NPR
The state of California is asking a basic question right now that people often fight over: What's a fair way to divide up something that's scarce and valuable? That "something," in this case, is water.
There's a lot at stake, including your very own nuts, fruit and vegetables, because most of the water that's up for grabs in California goes to farmers. This year, some farmers will get water, and others will not, simply based on when their land was first irrigated.
Consider, for instance, the case of Cannon Michael. He grows tomatoes and melons in California's Central Valley. And despite the drought, he'll still grow them this year.
Lifecycle of Today's Cell Phone
April 7, 2015 08:57 AM - ClickGreen Staff, ClickGreen
It is estimated that in 2014 over two billion mobile phones were sold worldwide. Of these, over one billion were estimated to be smartphones. It is also estimated that a massive 87% of the world’s population now use mobile phones. These are staggering figures, but how many of us have ever stopped to think of where our precious mobile phones came from and what happens to them once we discard them for a newer model?
Each year millions of mobile phones are produced in the world and an equal number are disposed of. In the vast majority of cases these discarded phones work perfectly well. However, like all technological products these days, phones have a built-in technological obsolescence (we demand the latest model or the latest upgrade) as well as a built in aesthetic obsolescence (we demand the latest style or design).
In spite of their extremely small size and simplicity of look, mobile phones are immensely complex pieces of technology with many, many components. If we stop to think about it for a moment all of these products need sourcing: the raw materials needed to produce them need extracting from the ground, these need to manufactured into working parts which are then assembled into the final phone.
Europe focuses on food safety on World Health Day
April 7, 2015 07:07 AM - EurActiv
On World Health Day (7 April), European Commissioners Vytenis Andriukaitis and Neven Mimica highlight the importance of food safety, malnutrition, and fighting health threats both in the Union and in developing countries.
2015 is the European year for development (EYD). It is an opportunity to show how EU assistance is improving the lives of millions in developing countries; but also in Europe. Food safety, which is the theme of this year’s World Health Day, is a clear example of this.
Too often in Europe we take for granted that the food on our plates is safe. Europe should be proud that its 500 million consumers benefit from the highest food safety and health protection standards in the world, and that many other countries take them as the norm to be followed. However, we must not become complacent.
White fat, brown fat, now beige fat and obesity
April 4, 2015 08:58 AM - Universtiy of California San Francisco
Those extra pounds around your belly that no amount of exercise seems to shake off? That's not just fat; it's what scientists call white fat – unhealthy, energy-storing fat.
Brown fat, however, has been known to contain energy-burning, heat-producing qualities that could be key to helping people lose weight. The key is finding a way to increase brown fat in the body and reduce the white fat.
Hibernating mammals have brown fat, and human babies are born with it to help them keep warm outside the womb. Adults also have varying amounts of brown fat, but researchers weren't sure if it’s the same kind babies are born with, and if not, where it comes from.
New California water restrictions mandated
April 2, 2015 06:56 AM - , Triple Pundit
This year California has seen the lowest snowpack ever recorded, which was a disaster for the winter ski tourism industry and poses dangers of wildfires this summer and fall. But the dry winter has also exacerbated the state’s ongoing drought crisis. To that end, Gov. Jerry Brown issued an executive order that he said is necessary in order to make California drought resistant.
The governor made the announcement while visiting a California Department of Water Resources snow survey in the Sierra Nevada Mountains at Phillips Station, located in El Dorado County near the Nevada border. “Today we are standing on dry grass where there should be five feet of snow. This historic drought demands unprecedented action,” Gov. Brown said.
The advantages of being a morning person
April 1, 2015 01:40 PM - Roger Greenway, ENN
There are many advantages of getting a good nights sleep. Turns out, the advantages are less if you are a night owl instead of a morning person.
Night owls are more likely to develop diabetes, metabolic syndrome and sarcopenia than early risers, even when they get the same amount of sleep, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
The study examined the difference between night and morning chronotypes, or a person's natural sleep-wake cycle. Staying awake later at night is likely to cause sleep loss, poor sleep quality, and eating at inappropriate times, which might eventually lead to metabolic change.
Lunch apparently not that appealing to children anymore
March 30, 2015 07:32 AM - Nestle via EurekAlert.
According to new analysis of data from the 2009-2012 National Health and Nutrition Examination Survey (NHANES) that evaluated eating patterns of 3,647 children ages 4-13 years, skipping lunch is a common practice among children and adolescents, with 13% of younger children and 17% of 9-13 year olds skipping lunch on a given day. The study found that the behavior persisted throughout the week with nearly a quarter (approximately 23%) of 9-13 year olds skipping lunch on the weekends. These findings, part of Nestlé's new Kids Nutrition & Health Study (KNHS), were presented today at a poster session entitled "What Happened to Lunch? Dietary Intakes of 4-13 Year Old Lunch Consumers and Non-Consumers in the United States" at the American Society of Nutrition conference.
These findings are of particular concern given that lunch skippers had lower intakes of nutrients, including calcium and fiber, than lunch consumers. In addition, the data show that for some children, the lunch meal was primarily responsible for the higher essential nutrient intakes of vitamin D, potassium and magnesium, as well as a nutrient of concern, sodium.
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'.
Which diet has the smallest carbon footprint?
March 26, 2015 01:20 PM - Spanish Foundation for Science and Technology, via EurekAlert!
The health benefits of the Mediterranean diet are well-known. As well as being healthier, a recent article concludes that the menu traditionally eaten in Spain leaves less of a carbon footprint than that of the US or the United Kingdom. The consequences of climate change range from species extinction to sea-level increases and the spread of diseases. For this reason, researchers have been struggling for years to alleviate its effects, even limiting the pollution caused by food consumption.
