CORVALLIS, Ore. - A compound with potential as a treatment for ALS has gained further promise in a new study that showed it improved the condition of mice whose motor neurons had been damaged by an environmental toxin known to cause features of ALS.
ALS patients are categorized either as familial - meaning two or more people in their family have had the disease, which in their case is linked to inherited genetic mutations - or sporadic, which accounts for about 90% of the cases. Sporadic means the cause or causes are unknown.
When it comes to cancer prevention messaging, clear information from trusted organizations has greater reach on social media than personal accounts of patients, new University of California, Davis, research suggests.
Irvine, Calif., July 1, 2019 - A catastrophic forest die-off in California's Sierra Nevada mountain range in 2015-2016 was caused by the inability of trees to reach diminishing supplies of subsurface water following years of severe drought and abnormally warm temperatures. That's the conclusion by researchers from the University of California, Irvine and UC Merced outlined in a study published today in Nature Geoscience.
University of Otago scientists are part of an international research collaboration which has made an important discovery in the quest to lower global agricultural methane emissions.
Professor Greg Cook, Dr Sergio Morales, Dr Xochitl Morgan, Rowena Rushton-Green and PhD student Cecilia Wang, all from the Department of Microbiology and Immunology, are members of the Global Research Alliance on Agricultural Greenhouse Gases that has identified new processes that control methane production in the stomach of sheep and similar animals like cattle and deer.
A team of international asteroid and comet experts now agree that Oumuamua, the first recorded interstellar visitor, has natural origins, despite previous speculation by some other astronomers that the object could be an alien spacecraft sent from a distant civilization to examine our star system.
Barcelona, Spain, 2 July 2019 - Stomach cancer should no longer be considered a disease only of older people, and patients under 40 with chronic digestive symptoms should be more actively investigated - especially if they are of Latin American ethnicity. This advice follows new data from a retrospective, observational study in Mexico which showed that one in seven of over 2,000 patients diagnosed with gastric cancer between 2004 and 2016 were under 40.
Despite being one of the nation's most vital watchdogs, compliance and enforcement actions by the U.S. Food and Drug Administration (FDA) have severely declined since the Trump administration took office, according to an investigative report from Charles Piller, a contributing correspondent in the News department at Science. The FDA is the principal federal agency responsible for protecting public health through the supervision and regulation of clinical trials, food safety, product recalls, medications and medical devices, among others.
Micro mechanical elements are indispensable components of modern electrical devices but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. As a way out of this issue, researchers demonstrated a new way to deliver a force to drive micro mechanics by spin current.
About 1 in 10 babies in the United States is born premature. These children are at an increased risk for adverse outcomes across a broad spectrum of neurodevelopmental domains, including language skills. They also are at an increased risk for attention-deficit/hyperactivity disorder (ADHD) as well as other behavioral problems.
Researchers at IDIBELL-ICO describe a new resistance mechanism to therapies that prevent the formation of blood vessels
The mechanism does not activate the reduction of oxygen in the cells of the tumor, contrary to what common drugs, called anti-angiogenic, usually cause.
In response to treatment, the immune cells of the tumor act as elements that make the tumor malignant.
What's good for one is not always best for all.
Solitary wind turbines produce the most power when pointing directly into the wind. But when tightly packed lines of turbines face the wind on wind farms, wakes from upstream generators can interfere with those downstream. Like a speedboat slowed by choppy water from a boat in front, the wake from a wind turbine reduces the output of those behind it.
Researchers who analyzed payroll-based staffing data for U.S. nursing homes discovered large daily staffing fluctuations, low weekend staffing and daily staffing levels that often fall well below the expectations of the Centers for Medicare and Medicaid Services (CMS), all of which can increase the risk of adverse events for residents.
A group of researchers funded by Neuroendocrine Tumor Research Foundation (NETRF) has discovered molecular information that may help predict recurrence of non-functional pancreatic neuroendocrine tumors (pNETs), which do not release excess hormones into the bloodstream. In a paper published today in Nature Medicine, the researchers describe new subtypes of pNETs with vastly different risks of recurrence.
For nine years running, Carolina professor Jodi Magness has led a team of research specialists and students to the ancient village of Huqoq in Israel's Lower Galilee, where they bring to light the remains of a Late Roman synagogue. For weeks during the summer, they unearth history in the form of art. With each excavation season, the students and researchers build on what little is known about the fifth century CE Jewish community of Huqoq and the artists who crafted depictions of biblical stories with tiny cubes of stone, or tesserae.
The formation of calcium carbonate (CaCO3) in water has ramifications for everything from food and energy production to human health and the availability of drinkable water. But in the context of today's environment, simply studying how calcium carbonate forms in pure water isn't helpful.
