Initial findings from the Walnuts and Healthy Aging (WAHA) study presented at Experimental Biology 2016 (EB) indicate that daily walnut consumption positively impacts blood cholesterol levels without adverse effects on body weight among older adults. The WAHA study is a dual site two-year clinical trial conducted by researchers from the Hospital Clinic of Barcelona and Loma Linda University and is aimed at determining the effect of walnuts on age-related health issues. 

"Given walnuts are a high-energy food, a prevailing concern has been that their long term consumption might be associated with weight gain," said Dr. Emilio Ros, director of the Lipid Clinic, Endocrinology & Nutrition Service at the Hospital Clinic of Barcelona. "The preliminary results of the WAHA study demonstrate that daily consumption of walnuts for one year by a sizable cohort of aging free-living persons has no adverse effects on body weight. They also show that the well-known cholesterol-lowering effect of walnut diets works equally well in the elderly and is maintained in the long term. Acquiring the good fats and other nutrients from walnuts while keeping adiposity at bay and reducing blood cholesterol levels are important to overall nutritional well-being of aging adults. It's encouraging to see that eating walnuts may benefit this particular population."

La formación de un cambio en el patrón de las temperaturas superficiales del mar en el medio del Océano Pacífico Norte puede predecir un mayor riesgo de olas de calor del verano en la mitad oriental de los EE. UU, con hasta 50 días de anticipación.

El patrón contrasta el agua más cálida que el promedio con el agua procedente de mares más fríos de lo normal. Cuando aparece, las probabilidades de que el calor extremo se deje sentir durante...

New opportunities to fight climate change in these properties are coming from an unlikely source: the commercial property lease. A new study finds that in 2009, only 15% of all leases signed in Sydney’s central business district contained green clauses; by 2013, this had risen to over 60%.

After nearly 50 years of service, Scotland’s last coal-fired power plant — Longannet Power Station — has finally gone offline, putting an end to over 100 years of burning coal for electricity.

It’s an important moment for Scottish Power, which looks ahead to clean power initiatives with the goal of going all-renewable by 2020,

But it’s also a very symbolic action for the world. Hopefully other nations will follow suit, creating a domino effect as country by country eliminates its coal plants — like the one above — in favor of renewable alternatives.

Oxford researchers have quantified the benefits of the world becoming vegetarian, writes Marco Springmann. Their study shows that simple changes - like moving to diets low in meat and high in fruit and vegetables - could lead to significant reduction in mortality and health care costs, while cutting food sector greenhouse gas emissions by two thirds.

Elderly adults are bigger around the middle when they turn up the heat inside their homes during the cold season and have smaller waistlines when their homes stay cool, new research finds. Investigators from Japan will present their study results Friday at the Endocrine Society's 98th annual meeting in Boston.

"Although cold exposure may be a trigger of cardiovascular disease, our data suggest that safe and appropriate cold exposure may be an effective preventive measure against obesity," said the study's lead investigator, Keigo Saeki, MD, PhD, of Nara Medical University School of Medicine Department of Community Health and Epidemiology, Nara, Japan.

Cold exposure activates thermogenesis, to generate body heat, in brown fat. This type of fat is the good calorie-burning fat that prior research found most humans have. However, Saeki said the association between the amount of cold exposure and obesity in real life remains unclear.
