Ocean channel in Bahamas marks genetic divide in Brazilian free-tailed bats

EurekAlert! Biology - Thu, 2017-08-17 21:00
(Florida Museum of Natural History) Brazilian free-tailed bats are expert flyers, capable of migrating hundreds of miles and regularly traveling more than 30 miles a night. But they pull up short at a narrow ocean channel that cuts across the Bahamas, dividing bat populations that last shared an ancestor hundreds of thousands of years ago.

New Bioimaging technique is fast and economical

EurekAlert! Biology - Thu, 2017-08-17 21:00
(Rensselaer Polytechnic Institute) A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue -- such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing.

Research reveals how physical exercise protects the heart

EurekAlert! Biology - Thu, 2017-08-17 21:00
(Fundação de Amparo à Pesquisa do Estado de São Paulo) A study by the University of São Paulo (USP) in Brazil, published recently in the journal Autophagy, helps to elucidate part of the mechanism whereby aerobic exercise protects the sick heart. The benefits of exercise range from prevention of cachexia -- severe loss of weight and muscle mass -- and control of arterial blood pressure to improved cardiac function, postponing a degenerative process that causes progressive heart cell death. About 70% of heart failure patients die from the condition within five years.

NJIT researchers will follow in the moon's slipstream to capture high-res sunspot images

EurekAlert! Materials - Thu, 2017-08-17 21:00
(New Jersey Institute of Technology) While much of the research around the eclipse on Monday will focus on the effects of the Sun's brief, daytime disappearance on Earth and its atmosphere, a group of solar physicists will be leveraging the rare event to capture a better glimpse of the star itself.

OU astrophysicist predicts detached, eclipsing white dwarfs to merge into exotic star

EurekAlert! Materials - Thu, 2017-08-17 21:00
(University of Oklahoma) A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries.

Paper: Clinical signs best predictors of mortality in critically ill calves

EurekAlert! Biology - Thu, 2017-08-17 21:00
(University of Illinois at Urbana-Champaign) Clinical signs such as gastrointestinal problems may be better predictors of mortality in neonatal calves with diarrhea than blood pH levels and other laboratory findings, suggests a new study co-written by University of Illinois veterinary medicine dean Peter Constable; Florian M. Trefz and Annette Lorch, both of the Center of Veterinary Clinical Medicine at Ludwig Maximilian University of Munich; and Ingrid Lorenz, of the Bavarian Animal Health Service.

GIST tumors linked to NF1 mutations, genetic testing needed

EurekAlert! Biology - Thu, 2017-08-17 21:00
(University of California - San Diego) Researchers at UC San Diego Moores Cancer Center, with colleagues from Memorial Sloan Kettering Cancer Center and Fox Chase Cancer Center, have determined that a specific region of the small bowel, called the duodenal-jejunal flexure or DJF, shows a high frequency of gastrointestinal stromal tumors (GISTs) with mutations of the NF1 gene.

Mechanisms explaining positional diversity of the hindlimb in tetrapod evolution

EurekAlert! Biology - Thu, 2017-08-17 21:00
(Nagoya University) Elucidating how body parts in their earliest recognizable form are assembled in tetrapods during development is essential for understanding the nature of morphological evolution. Nagoya University researchers found in eight tetrapod species that the position of the sacral vertebrae and the hindlimbs is determined by the initiation timing of Gdf11 gene expression. This will contribute to a forthcoming model explaining the coupling of spine and hindlimb positioning - a major step in fully understanding tetrapod evolution.

Spoiler alert: Computer simulations provide preview of next week's eclipse

EurekAlert! Materials - Thu, 2017-08-17 21:00
(University of Texas at Austin, Texas Advanced Computing Center) Researchers from Predictive Science Inc. used NASA and National Science Foundation-supported supercomputers to run highly-detailed forecasts of the Sun's corona -- the aura of plasma that surrounds the sun -- at the moment of the eclipse. The team combined data from NASA's Solar Dynamics Observatory, magnetic field maps, solar rotation rates and cutting-edge mathematical models to predict the state of the Sun's surface. The simulations are the largest produced by the group and include new physics.
