Make way for hemoglobin

EurekAlert! - Jue, 08/17/2017 - 22:00
Harvard Medical School researchers have identified the mechanism behind red blood cell specialization and revealed that it is controlled by an enzyme called UBE2O. This finding could spark the development of new treatments for blood disorders and cancers.

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

EurekAlert! - Jue, 08/17/2017 - 22:00
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.

Smokers 20 percent more likely to quit when cigarettes cost $1 more

EurekAlert! - Jue, 08/17/2017 - 22:00
Smokers were found to be 20 percent more likely to quit smoking when packs of cigarettes cost just one dollar more, according to a new public health study out of Drexel University.

GIST tumors linked to NF1 mutations, genetic testing needed

EurekAlert! - Jue, 08/17/2017 - 22:00
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.

ASTRO supports US Nuclear Regulatory Commission final rule

EurekAlert! - Jue, 08/17/2017 - 22:00
The American Society for Radiation Oncology (ASTRO) applauds the United States Nuclear Regulatory Commission for yesterday's announcement of a final rule that updates the definition of medical events for permanent implant brachytherapy and protects patients' access to this treatment.

Despite benefits, half of parents against later school start times

EurekAlert! - Jue, 08/17/2017 - 22:00
Leading pediatrics and sleep associations agree: Teens shouldn't start school so early. Yet University of Michigan research finds parents are split almost down the middle on whether they support delays in school start times that might permit their 13- to 17-year-olds to sleep later on school days.

NASA gets a final look at Hurricane Gert's rainfall

EurekAlert! - Jue, 08/17/2017 - 22:00
Before Hurricane Gert became a post-tropical cyclone, NASA got a look at the rainfall occurring within the storm. After Gert became post-tropical NOAA's GOES-East satellite captured an image as Gert was merging with another system.

Hot spot at Hawaii? Not so fast

EurekAlert! - Jue, 08/17/2017 - 22:00
Rice University geophysicists use a new model to conclude that volcanic hot spots around the globe aren't moving as fast as recently thought.

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

EurekAlert! - Jue, 08/17/2017 - 22:00
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.

Can Twitter aid disaster response? New IST research examines how

EurekAlert! - Jue, 08/17/2017 - 22:00
With over 500 million tweets sent every single day, new research from the Penn State College of Information Sciences and Technology (IST) is investigating innovative ways to use that data to help communities respond during unexpected catastrophes.

Mechanisms explaining positional diversity of the hindlimb in tetrapod evolution

EurekAlert! - Jue, 08/17/2017 - 22:00
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.

Scientists from the MSU studied new liquid-crystalline photochrom

EurekAlert! - Jue, 08/17/2017 - 22:00
Members of the Faculties of Chemistry and Fundamental Physical and Chemical Engineering at the Lomonosov Moscow State University in collaboration with foreign partners have synthesized and studied new liquid-crystal photochromic polymers. The research has been fulfilled within the framework of the project, funded by the Russian Science Foundation.

Organ crosstalk: Fatty liver can cause damage to other organs

EurekAlert! - Jue, 08/17/2017 - 22:00
Scientists of the German Center for Diabetes Research (DZD) in Tübingen discovered that a fatty liver can cause damage to other organs. In two just-published studies they demonstrate the effects of fatty liver disease on the function of the hormone-producing islet cells in the pancreas and on renal function.

Vitamin D deficiency linked to increased heart failure risk in older adults

EurekAlert! - Jue, 08/17/2017 - 22:00
A recent study found an elevated risk of heart failure in more than half of older individuals, and this risk was significantly associated with vitamin D deficiency.

A map of the cell's power station

EurekAlert! - Jue, 08/17/2017 - 22:00
Researchers from the University of Freiburg are mapping the distribution of all proteins in mitochondria for the first time.

Researchers discover new chemical process that could reduce nitrogen oxides from diesel exhaust

EurekAlert! - Jue, 08/17/2017 - 22:00
Chemical engineers at the University of Notre Dame have discovered a catalytic process that could help curb emissions of nitrogen oxides from diesel-powered vehicles, a priority air pollutant that is a key ingredient in smog.

Population health impact of infants born small for gestational age in low- and middle-income countries

EurekAlert! - Jue, 08/17/2017 - 22:00
Researchers at Brigham and Women's Hospital and CHERG used the first international, multi-ethnic birth weight standard, known as the INTERGROWTH-21st, to describe the global burden of suboptimal fetal growth.

Special issue of Future Medicinal Chemistry explores immunotherapy edit article

EurekAlert! - Jue, 08/17/2017 - 22:00
The field of immunotherapy is moving forward at an unprecedented rate and cancer immunotherapy, in particular, has recently come of age!

Virus with an eggshell

EurekAlert! - Jue, 08/17/2017 - 22:00
Avian flu can be transmitted from birds to humans; transmission among humans, however, is limited. The reason may be an eggshell-like mineral layer that the virus acquires due to the high calcium concentration in the intestines of birds. As reported by Chinese researchers in the journal Angewandte Chemie, these mineralized viruses are significantly more infectious and, in addition, more robust and heat stable than the native viruses.
