Raised blood platelet levels 'strong predictor' of cancer

EurekAlert! - Dom, 05/21/2017 - 22:00
Having a high blood platelet count is a strong predictor of cancer and should be urgently investigated to save lives, according to a large-scale study.

Intensive blood pressure can reduce risk of harm to heart muscle

EurekAlert! - Dom, 05/21/2017 - 22:00
A new study by researchers at Wake Forest Baptist Medical Center has shown that aggressive lowering of blood pressure in people with hypertension reduced the risk of left ventricular hypertrophy (LVH). This condition, the enlargement and thickening of the walls of the heart's main pumping chamber, is the most common complication of high blood pressure and greatly increases the risk of developing cardiovascular disease.

Researchers suppress fibrosis chemical signal to block haywire healing

EurekAlert! - Dom, 05/21/2017 - 22:00
An injured body always seeks to heal. But that process is far from simple. A host of cells organize to restore what was damaged. Then, critically, the process tapers off. And when it doesn't, the effects can be disastrous. Fibrosis is the thickening and scarring of tissue due to an overactive healing response.

Supercomputing helps researchers understand Earth's interior

EurekAlert! - Dom, 05/21/2017 - 22:00
University of Illinois geologist Lijun Liu and his team have created a computer model of tectonic activity so effective that they believe it has potential to predict where earthquakes and volcanoes will occur. Liu, along with doctoral student Jiashun Hu, and Manuele Faccenda from the University of Padua in Italy, published a research paper in the journal of Earth and Planetary Science Letters focusing on the deep mantle and its relationship to plate tectonics.

Study identifies RNA molecule that shields breast cancer stem cells from immune system

EurekAlert! - Dom, 05/21/2017 - 22:00
Researchers from Princeton University's Department of Molecular Biology have identified a small RNA molecule that helps maintain the activity of stem cells in both healthy and cancerous breast tissue. The study, which will be published in the June issue of Nature Cell Biology, suggests that this 'microRNA' promotes particularly deadly forms of breast cancer and that inhibiting the effects of this molecule could improve the efficacy of existing breast cancer therapies.

Humanizing, harmonizing effects of music aren't a myth

EurekAlert! - Dom, 05/21/2017 - 22:00
UA professor Jake Harwood and his collaborators have found that listening to music from other cultures furthers one's pro-diversity beliefs. The findings have important implications for music education, K-12 education and efforts to improve cross-cultural intergroup dialogue and communication.

Discovery of an alga's 'dictionary of genes' could lead to advances in biofuels, medicine

EurekAlert! - Dom, 05/21/2017 - 22:00
A team of plant biologists and biochemists has produced a gold mine of data by sequencing the genome of a tiny, single-celled green alga that could be used as a source of sustainable biofuel and has health implications.

SAEM 2017: EM physicians should stay current on studies to up their critical care game

EurekAlert! - Dom, 05/21/2017 - 22:00
Reviewing studies can be a tedious task, but one Michigan Medicine physician explains the importance of staying up to date on medical literature, even outside of one's primary field of medicine.

Genes responsible for severe congenital heart disease identified by Pitt researcher

EurekAlert! - Dom, 05/21/2017 - 22:00
Genes responsible for hypoplastic left heart syndrome identified using mouse models.

NASA lab's life-saving work

EurekAlert! - Dom, 05/21/2017 - 22:00
Some NASA missions fundamentally change the world of science or help win Nobel prizes, but only one saves thousands of lives worldwide every year.

3.3 million-year-old fossil reveals the antiquity of the human spine

EurekAlert! - Dom, 05/21/2017 - 22:00
An international research team has found a 3.3 million Australopithecus afarensis fossilized skeleton, possessing the most complete spinal column of any early fossil human relative. The vertebral bones, neck and rib cage are mainly intact. This new research, published today in the Proceedings of the National Academy of Science demonstrates that portions of the human skeletal structure were established millions of years earlier than previously thought.

ATS 2017: New COPD action plan outlines strategies for improved care

EurekAlert! - Dom, 05/21/2017 - 22:00
A Michigan Medicine researcher is a part of the National Institutes of Health's National Heart, Lung and Blood Institute group that recently created a new COPD National Action Plan. Released at the American Thoracic Society's International Conference in Washington, D.C., it outlines key goals, including raising public awareness of COPD, advancing research, improving patient care and health delivery, and developing management strategies for patients.

The Optical Society commemorates the rich tradition and history of Optics Letters

EurekAlert! - Dom, 05/21/2017 - 22:00
First launched in 1977 as as means to quickly disseminate the latest in optics research and provide the optics and photonics community with a true Letters-style publication, Optics Letters has, over the course of its long history, published influential papers in nonlinear optics, ultrafast spectroscopy, fiber optics, optical communication, and biomedical optics among other areas. This year the Journal celebrates its 40th anniversary and The Optical Society (OSA) has launched a special website to highlight this milestone.

RIT team creates high-speed internet lane for emergency situations

EurekAlert! - Dom, 05/21/2017 - 22:00
Rochester Institute of Technology are developing a faster and more reliable way to send and receive large amounts of data through the internet. By a creating a new network protocol, called Multi Node Label Routing protocol, researchers are essentially developing a new high-speed lane of online traffic, specifically for emergency information.

Research suggests eating beans instead of beef would sharply reduce greenhouse gasses

EurekAlert! - Dom, 05/21/2017 - 22:00
If Americans would eat beans instead of beef, the United States would immediately realize approximately 50 to 75 percent of its GHG reduction targets for the year 2020.

Joint UTSA-SwRI study shows how radioactive decay could support extraterrestrial life

EurekAlert! - Dom, 05/21/2017 - 22:00
In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a University of Texas at San Antonio (UTSA) and Southwest Research Institute (SwRI) team modeled a natural water-cracking process called radiolysis. They then applied the model to several worlds with known or suspected interior oceans, including Saturn's moon Enceladus, Jupiter's moon Europa, Pluto and its moon Charon, as well as the dwarf planet Ceres.

Rethinking role of viruses in coral reef ecosystems

EurekAlert! - Dom, 05/21/2017 - 22:00
Viruses are thought to frequently kill their host bacteria, especially at high microbial density. A state called lysogeny, in which viruses lie dormant but don't kill their hosts, has been thought to be relatively rare , mostly occurring at low bacterial concentrations. A new study suggests lysogeny might be much more common than previously believed. These findings could lead to a better understanding of degraded coral reef ecosystems and how to preserve them.

Extreme preterm infant death or disease may be predicted by biomarker

EurekAlert! - Dom, 05/21/2017 - 22:00
Tests of cells collected from the umbilical cord blood vessel walls at birth can predict death or poor pulmonary outcomes in extremely preterm infants, say researchers at the University of Alabama at Birmingham.
