Study suggests vaping does not stain teeth

EurekAlert! - Vie, 03/23/2018 - 22:00
Scientists at British American Tobacco have studied the impact of the vapor from Vype, an e-cigarette and glo, a tobacco-heating-product, on teeth and compared it to that of cigarette smoke. The results show that teeth exposed to Vype e-cigarette vapor or vapor from glo do not become stained, whereas teeth exposed to cigarette smoke became stained very quickly.

Brain development disorders in children linked to common environmental toxin exposures

EurekAlert! - Jue, 03/22/2018 - 22:00
Exposures of pregnant women and children to common thyroid-hormone-disrupting toxins may be linked to the increased incidence of brain development disorders, according to a review published in Endocrine Connections. The review describes how numerous, common chemicals can interfere with normal thyroid hormone actions, which are essential for normal brain development in fetuses and young children, and suggests a need for greater public health intervention.

For patients with drug-resistant infections, infectious diseases experts may be lifesaving

EurekAlert! - Jue, 03/22/2018 - 22:00
Researchers analyzed records for approximately 4,200 patients with infections resistant to multiple antibiotics from 2006 to 2015 at one academic medical center. Thirty-day mortality rates were about 50 percent lower among patients with certain multidrug-resistant infections who had infectious diseases (ID) specialists involved in their care. Among patients with Enterobacteriaceae infections resistant to several antibiotics, an ID consultation was associated with a 59 percent reduction in 30-day mortality.

Arctic wintertime sea ice extent is among lowest on record

EurekAlert! - Jue, 03/22/2018 - 22:00
Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.

Gene boosts rice growth and yield in salty soil

EurekAlert! - Jue, 03/22/2018 - 22:00
Soil salinity poses a major threat to food security, greatly reducing the yield of agricultural crops. Rising global temperatures are expected to accelerate the buildup of salt in soil, placing an increasing burden on agricultural production. In a new study published in The Plant Cell, a team of researchers identified a gene that limits yield losses in rice plants exposed to salt stress and deciphered the underlying mechanism.

Montana State University researchers publish study

A new field instrument developed by a collaborative team of CU Boulder researchers can detect and quantify methane leaks as tiny as one-quarter of a human exhalation from nearly a mile away.

Research discovers how some cancers resist treatment

EurekAlert! - Jue, 03/22/2018 - 22:00
An international team of researchers led by Lucio Miele, M.D., Ph.D., Professor and Chair of Genetics at LSU Health New Orleans School of Medicine, and Justin Stebbing, BM BCh MA, Ph.D, Professor of Cancer Medicine and Medical Oncology at Imperial College of Medicine in London, has found new genetic mutations that promote the survival of cancer cells. The research also provided a clearer understanding of how some cancer cells are able to resist treatment.

First proof a synthesized antibiotic is capable of treating superbugs

EurekAlert! - Jue, 03/22/2018 - 22:00
A 'game changing' new antibiotic which is capable of killing superbugs has been successfully synthesized and used to treat an infection for the first time -- and could lead to the first new class of antibiotic drug in 30 years.

New innovations in cell-free biotechnology

Increasing temperatures in cooling systems

EurekAlert! - Jue, 03/22/2018 - 22:00
For the very first time, scientists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Leicester and the University of Vigo have proven that the kinetic energy from particles in granular gases such as dust clouds can rise temporarily even though energy is constantly being drawn out of the system. Their research adds further detail to Haff's law (devised 35 years ago), which states that the granular temperature in closed systems continually decreases.

Team discovers a significant role for nitrate in the Arctic landscape

EurekAlert! - Jue, 03/22/2018 - 22:00
Because of the very low nitrate levels found in arctic tundra soil, scientists had assumed that plants in this biome do not use nitrate. But a new study co-authored by four Marine Biological Laboratory (MBL) Ecosystems Center scientists challenges this notion. The study has important implications for predicting which arctic plant species will dominate as the climate warms, as well as how much carbon tundra ecosystems can store.

Decades of research identify source of galaxy-sized stream of gas

EurekAlert! - Jue, 03/22/2018 - 22:00
A cloud of gas 300,000 light-years long is arching around the Milky Way, shunted away from two dwarf galaxies orbiting our own. For decades, astronomers have wanted to know which of the two galaxies, the Large and Small Magellanic Clouds, is the source of the gas that has been expelled as the two galaxies gravitationally pull at one another. The answer will help astronomers understand how galaxies form and change over time.

Older adults who have slower walking speeds may have increased risk for dementia

EurekAlert! - Jue, 03/22/2018 - 22:00
Because there's currently no cure for dementia, it's important to know about risk factors that may lead to developing it. For example, researchers have learned that older adults with slower walking speeds seem to have a greater risk than those with faster walking speeds. Recently, researchers from the UK. teamed up to learn more about changes in walking speed, changes in the ability to think and make decisions, and dementia.
