High-intensity exercise delays Parkinson's progression

Eurekalert - 23 hours 35 min ago
High-intensity exercise three times a week is safe for individuals with early-stage Parkinson's disease and delays progression of motor symptoms, reports a new study of individuals with the disease. The exercise needs to between 80 and 85 percent maximum heart rate for the benefit. It's the first time high-intensity exercise has been tested in Parkinson's patients. It was previously thought it was too physically stressful for patients.

Presenting facts as 'consensus' bridges conservative-liberal divide over climate change

Eurekalert - 23 hours 35 min ago
New evidence shows that 'social facts' highlighting expert consensus changes perceptions across US political spectrum -- particularly among highly educated conservatives. Facts that encourage agreement are a promising way of cutting through today's 'post-truth' bluster, say psychologists.

Tiny ice losses at Antarctica's fringes can accelerate ice loss far away

Eurekalert - 23 hours 35 min ago
It is known that the ice shelves surrounding the continent regulate the ice flow from the land into the ocean. Now scientists found that also melting near the fringes and in the midst of the ice shelves can have direct effects reaching very far inland. This could increase ice loss and hence sea-level rise.

The origin of the Andes unravelled

Eurekalert - 23 hours 35 min ago
Why do the Andes exist? Why is it not a place of lowlands or narrow seas? Wouter Schellart, a geophysicist at the Vrije Universiteit Amsterdam, has been pondering these questions for more than a decade. Now, he has found the answers using an advanced computer model. "It's a matter of enormous size, longevity and great depth", he said. "These aspects made the Andes the longest and second-highest mountain belt in the world."

AGU Fall Meeting: Mistletoe is 'kiss of death' to drought-stressed trees

Eurekalert - 23 hours 35 min ago
Around the holidays, a sprig of mistletoe over a doorway is festive and romantic. But mistletoe has a sinister side: The parasitic plant can sometimes kill the very tree it depends on for food by robbing its host of water during dry spells, according to new research being presented here.

Sustainable dams -- are they possible?

Eurekalert - 23 hours 35 min ago
Humans have been altering natural waterways for centuries, but only in the last several decades have dams raised ecological concerns.N. LeRoy Poff, professor of biology at Colorado State University, studies the ecological impact to rivers from human-caused changes, such as dam building, and how these modified river systems can be managed for resilience.In a Perspective piece in the journal Science, Poff writes on the state of research in sustainable dam design.

Bioengineering and specialized therapies yield results for rare, challenging blood diseases

Eurekalert - 23 hours 35 min ago
In four studies being presented today during the 59th American Society of Hematology (ASH) Annual Meeting and Exposition in Atlanta, researchers announce promising findings on innovative tools and therapies for hard-to-treat blood disorders including sickle cell disease (SCD), beta thalassemia, and X-linked severe combined immunodeficiency (X-SCID). The studies employ unique therapeutic approaches and advanced engineering technologies such as the gene-editing platform CRISPR/Cas9, reflecting the fruits of many years of research dedication and innovation.

'Death receptors' -- New markers for type 2 diabetes and cardiovascular disease

Eurekalert - 23 hours 35 min ago
Researchers at Lund University in Sweden have found that the presence of death receptors in the blood can be used to directly measure the risk of developing cardiovascular diseases and type 2 diabetes. 'We see that people with known risk factors such as high blood sugar and high blood fats also have heightened death receptor levels', says Professor Jan Nilsson who led the study.
