Low-energy sweetners do help reduce calorie intake
November 10, 2015 08:25 AM - University of Bristol
Use of low energy sweeteners (LES) in place of sugar, in children and adults, leads to reduced calorie intake and body weight – and possibly also when comparing LES beverages to water – according to a review led by researchers at the University of Bristol published in the International Journal of Obesity today.
For the first time, all available science was integrated into a single review to evaluate the real impact of LES, such as saccharin, aspartame, sucralose and stevia, on energy intake (EI) and body weight (BW) over the short- and long-term. A considerable weight of evidence confirmed that consuming LES instead of sugar helps reduce relative energy intake and body weight.
Do you get the Winter blah's? Light therapy might not be the best treatment.
November 5, 2015 08:02 AM - UNIVERSITY OF VERMONT via EurekAlert
A new study to be published online November 5 in the American Journal of Psychiatry casts a shadow on light therapy's status as the gold standard for treating SAD, or seasonal affective disorder.
While the treatment was effective at addressing acute episodes of SAD, a SAD-tailored version of cognitive-behavioral therapy (CBT) was significantly better at preventing relapse in future winters, the study found. Led by University of Vermont psychology professor Kelly Rohan, the research initiative, funded by a $2 million grant from the National Institute of Mental Health, is the first large scale study to examine light therapy's effectiveness over time.
Nuclear waste site near St Louis threatened by landfill fire
November 3, 2015 07:49 AM - Véronique LaCapra/St. Louis Public Radio, NPR
Imagine you are a parent, and that out of the blue, you get a letter from your child's school telling you not to worry — that they're ready to evacuate or shelter in place if an underground fire at a nearby landfill reaches radioactive waste on the same property.
That's pretty much what happened recently in suburban St. Louis.
Landfill fires are pretty common. But this one is different: It's only about a thousand feet away from nearly 9,000 tons of nuclear waste — and there's no barrier in between.
Dancing makes you feel good and help bond with others
October 28, 2015 08:49 AM - Universtiy of Oxford
Dancing in time with others raises your pain threshold, Oxford University researchers have found.
A team from the University's Experimental Psychology and Anthropology Departments wanted to see whether our feelings of social closeness when dancing with others might be linked to endorphins – the body’s 'feel good' chemicals.
Endorphins are neurotransmitters that form part of the brain’s pain control system, but they are also implicated in social bonding. Dr Bronwyn Tarr explained: 'Dance is an important activity around the world, and it could be a way to connect with other people and feel socially bonded. We wanted to see the effect of high and low energy, and synchronised and unsynchronised dancing had on both pain threshold and the sense of bondedness to fellow group-members.'
Is tattoo ink safe?
October 16, 2015 11:35 AM - Smithsonian News
Tattoos really are more than skin deep—and that raises questions about their safety.
Many people enjoy the aesthetic beauty of tattoos. But the brightly colored inks that make tattoos so vibrant and striking also carry health concerns, report authors of a new paper related to tattoo safety.
According to the Pew Research Center, 45 million Americans have at least one tattoo; roughly $1.65 billion is spent on tattoos each year in the U.S.
Solar powered water purification
October 8, 2015 06:48 AM - Jennifer Chu | MIT News Office
Deep in the jungles of the Yucatan peninsula, residents of the remote Mexican village of La Mancalona are producing clean drinking water using the power of the sun.
For nearly two years now, members of the community, most of whom are subsistence farmers, have operated and maintained a solar-powered water purification system engineered by researchers at MIT.
The system consists of two solar panels that convert sunlight into electricity; these, in turn, power a set of pumps that push water through semiporous membranes in a filtration process called reverse osmosis. The setup purifies both brackish well water and collected rainwater, producing about 1,000 liters of purified water a day for the 450 residents.
The Gypsies problem in Europe
October 4, 2015 07:34 AM - Dan Allen, University of Salford, The Ecologist
Under new planning rules, Travellers and Gypsies must be able to prove they are actually traveling to qualify for limited planning benefits to create new sites. But for many, it's impossible to do that. Not only to remain in employment, or education - but precisely because there are so few sites, that they are unable to travel.
Living on an unauthorised campsite carries a heavy weight of suffering and disadvantage. Travellers contend daily with the risk of criminalisation and eviction, as well as limited access to basic services such as running water and sanitation.
Any attempt to subsume diverse groups under one label is going to be fraught with tension - and this is certainly true in terms of the word 'Traveller'.
Do you favor hotels that ask you to reuse your towels?
October 2, 2015 06:40 AM - ClickGreen staff, ClickGreen
Hotels across the globe are increasingly encouraging guests to embrace green practices. Yet while guests think they are supporting the environment by shutting off lights and reusing towels, they may in fact be victims of "greenwashing," a corporation's deceitful practice of promoting environmentally friendly programmes while banking the extra profits.
Greenwashing practices, such as a sign that reads "save the planet: re-use towels," coupled with claims of corporate social responsibility, have soiled the trust of American consumers who are increasingly recognizing hotels' green claims may be self-serving. This could cause hotels to lose valuable repeat customers.
Cancer drug found to sharpen memory, potential for Alzheimer's treatment
October 2, 2015 06:13 AM - Robin Lally, Rutgers University
Can you imagine a drug that would make it easier to learn a language, sharpen your memory and help those with dementia and Alzheimer’s disease by rewiring the brain and keeping neurons alive?
People with a dementia such as Alzheimer's disease lose their memory when brain cells shrink and die because connections can no longer transfer information.
New Rutgers research published in the Journal Neuroscience found that a drug – RGFP966 – administered to rats made them more attuned to what they were hearing, able to retain and remember more information, and develop new connections that allowed these memories to be transmitted between brain cells.
The Volkswagen emissions cheating scandal and it's potential impact on VW owners
October 1, 2015 06:53 AM - YUKI NOGUCHI, NPR
Out of the 250 million cars and trucks on U.S. roads, the impending recall at Volkswagen will involve just a half-million of them. But VW's emissions cheating scandal is receiving outsize attention because many of the company's customers feel duped. Now those customers are weighing what it will take to make them feel whole again.
David Chien of Williston, Vt., was looking for a bigger, fuel-efficient car that could power its way through Northeastern snow. He says the 2013 Jetta SportWagen he bought "seemed to check all the boxes."
