Rising sea temperatures threaten survival of juvenile albatross

EurekAlert! - Dom, 06/17/2018 - 22:00
Changes in sea surface temperature affect the survival of albatross during their first year at sea, resulting in a reduced population growth rate when temperatures are warmer than the current average, a new study published in the Journal of Animal Ecology has revealed.

Diabetes may be an early manifestation of pancreatic cancer

EurekAlert! - Dom, 06/17/2018 - 22:00
A new study in the Journal of the National Cancer Institute indicates that recent-onset type 2 diabetes may be early expression of pancreatic cancer. Diabetes was associated with a more than twofold higher risk of pancreatic cancer in African-Americans and Latinos, but recent-onset diabetes was associated with a 2.3-fold greater increase in risk of pancreatic cancer than long-standing diabetes.

When it comes to weight loss in overweight and obese adults with knee osteoarthritis, more is better

EurekAlert! - Dom, 06/17/2018 - 22:00
Researchers previously showed that overweight and obese individuals with knee osteoarthritis can reduce pain by 50 percent and significantly improve function and mobility with a 10 percent or more weight loss over an 18-month period.

Researchers find a promising new approach for treating liver cirrhosis

EurekAlert! - Dom, 06/17/2018 - 22:00
In a study in The American Journal of Pathology, investigators report that treatment with aleglitazar, a dual peroxisome proliferator-activated receptor-alpha/gamma (PPARα/γ) agonist, reduced inflammation, vasoconstriction, angiogenesis, mucosal disruption, and tumor necrosis factor (TNF)-α overproduction in cirrhotic rats with PH. This suggests a promising new approach for treating liver cirrhosis.

One in 5 parents did not talk to kids about what to do if they got lost at an amusement park

EurekAlert! - Dom, 06/17/2018 - 22:00
New report indicates several opportunities to reduce safety risks for children in the amusement park environment.

Sensitive new assay finds abnormalities in tumor cells that other techniques may miss

EurekAlert! - Dom, 06/17/2018 - 22:00
RNA-Seq, a new next-generation assay, can detect gene fusions in solid tumor cells with high accuracy and excellent reproducibility. According to a new report in The Journal of Molecular Diagnostics, the assay detected 93 percent of gene fusions identified by currently available methods with no false positives. Importantly, gene fusions missed by other techniques were found, including 18 that had never been described before. This study paves the way for clinical use to advance the diagnosis and treatment of solid tumors.

Large outdoor study shows biodiversity improves stability of algal biofuel systems

EurekAlert! - Dom, 06/17/2018 - 22:00
A diverse mix of species improves the stability and fuel-oil yield of algal biofuel systems, as well as their resistance to invasion by outsiders, according to the findings of a federally funded outdoor study by University of Michigan researchers.

New technique provides accurate dating of ancient skeletons

EurekAlert! - Sáb, 06/16/2018 - 22:00
A new way of dating skeletons by using mutations in DNA associated with geography will avoid the difficulties and inaccuracies sometimes associated with existing dating methods. The technique will enable a better understanding of historical developments from the beginning of the Neolithic period, through the Bronze and Iron Ages.

Genomic testing for the causes of stillbirth should be considered for routine use

EurekAlert! - Sáb, 06/16/2018 - 22:00
The use of whole genome and whole exome sequencing can uncover the cause of unexplained stillbirth and neonatal deaths. In addition to providing an explanation to bereaved parents, it can help the understand whether a recurrence in future pregnancies is likely.

Gut microbes may contribute to depression and anxiety in obesity

EurekAlert! - Sáb, 06/16/2018 - 22:00
Like everyone, people with type 2 diabetes and obesity suffer from depression and anxiety, but even more so. Researchers at Joslin Diabetes Center now have demonstrated a surprising potential contributor to these negative feelings -- and that is the bacteria in the gut or gut microbiome, as it is known.

Diabetes diagnosis may signal early pancreatic cancer in older African-Americans, Latinos

EurekAlert! - Sáb, 06/16/2018 - 22:00
A new study from the Keck School of Medicine of USC shows that African-Americans and Latinos who are diagnosed with diabetes after age 50 have a more than threefold risk of developing pancreatic cancer.

Life in the fast lane: USU ecologist says dispersal ability linked to plants' life cycles

EurekAlert! - Sáb, 06/16/2018 - 22:00
Utah State University ecologist Noelle Beckman says seed dispersal is an essential, yet overlooked, process of plant demography, but it's difficult to empirically observe, measure and assess its full influence.
