A new study finds people who have mild cognitive impairment (MCI), which lies on the continuum of cognitive decline between normal cognition and dementia, are less likely to receive proven heart attack treatment in the hospital.
Researchers found no evidence that those with MCI would derive less benefit from evidence-based treatment that's offered to their cognitively normal peers who have heart attacks, says lead author Deborah Levine, M.D., MPH.
University of Calgary researchers at the Cumming School of Medicine (CSM) led by Drs. Donna Senger, PhD, Paul Kubes, PhD, and Stephen Robbins, PhD have discovered a new way to stop harmful inflammation in the lungs due to sepsis and injury.
An international group of scientists studied the effects of 17 different lifespan-extending interventions on gene activity in mice and discovered genetic biomarkers of longevity. The results of their study were published in the journal Cell Metabolism.
Stanford, CA (Aug 22, 2019) -- As sea levels rise, many communities will be forced to relocate or be swallowed by the sea. Yet, retreat--relocation of communities in response to natural hazards and climate impacts--remains immensely controversial, and getting people and governments to plan for it is an uphill battle on several fronts. Below, researchers A.R. Siders, Miyuki Hino and Katharine Mach discuss their related article, published in the journal Science, on why, where, when and how communities should plan for retreat.
The first detailed map of individual malaria parasite behaviour across each stage of its complicated life cycle has been created by scientists. Researchers at the Wellcome Sanger Institute and their collaborators used advanced single-cell technology to isolate individual parasites and measure their gene activity. The result is the Malaria Cell Atlas, which gives the highest resolution view of malaria parasite gene expression to date and monitors how individual parasites change as they develop in both the mosquito and human host.
Just when international fears of contracting Zika began to fade in 2017, an undetected outbreak was peaking in Cuba--a mere 300 miles off the coast of Miami. A team of scientists at Scripps Research, working in concert with several other organizations, uncovered the hidden outbreak by overlaying air-travel patterns with genomic sequencing of virus samples from infected travelers. The discovery is featured on the cover of the Aug. 22 issue of Cell.
RESEARCH TRIANGLE PARK, N.C. (August 22, 2019) - For the first time, scientists built a synthetic biologic system with compartments like real cells. This Army project at the University of Massachusetts Amherst could lead to materials that provide new avenues to deliver medicine, treat wounds and purify water for Soldiers.
A 100-year flood is supposed to be just that: a flood that occurs once every 100 years, or a flood that has a one-percent chance of happening every year.
But Princeton researchers have developed new maps that predict coastal flooding for every county on the Eastern and Gulf Coasts and find 100-year floods could become annual occurrences in New England; and happen every one to 30 years along the southeast Atlantic and Gulf of Mexico shorelines.
PHOENIX, Ariz. -- Aug. 22, 2019 -- An international team of researchers led by Yale University, University of Iowa, and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, has discovered a new pathway that may improve success against an incurable type of children's brain cancer.
The study results, published today in Nature Communications, suggest that scientists have identified a unique way to disrupt the cellular process that contributes to Diffuse Intrinsic Pontine Gliomas (DIPG).
For every acre of mule deer habitat taken by roads, well pads and other oil and gas development infrastructure in Wyoming's Green River Basin, an average of 4.6 other acres of available forage is lost, according to new research by University of Wyoming scientists.
That's because deer avoid areas close to such human disturbance, even when there's quality forage in those areas, says the research published in the journal Ecological Applications.
Over the past 300 years, 79 plants have been confirmed extinct from three of the world's biodiversity hotspots located in South Africa - the Cape Floristic Region, the Succulent Karoo, and the Maputuland-Pondoland-Albany corridor.
For the world's estimated 1.8 billion Muslims -- roughly one-quarter of the world population -- making a pilgrimage to Mecca is considered a religious duty that must be performed at least once in a lifetime, if health and finances permit. The ritual, known as the Hajj, includes about five days of activities, of which 20 to 30 hours involve being outside in the open air.
CAMBRIDGE, MA - Using a technique that can precisely edit DNA bases, MIT researchers have created a way to store complex "memories" in the DNA of living cells, including human cells.
The new system, known as DOMINO, can be used to record the intensity, duration, sequence, and timing of many events in the life of a cell, such as exposures to certain chemicals. This memory-storage capacity can act as the foundation of complex circuits in which one event, or series of events, triggers another event, such as the production of a fluorescent protein.
NASA's Terra satellite passed over the Northwestern Pacific Ocean and captured an image of newly developed Tropical Depression Bailu, east of the Philippines.
On Aug. 20, 2019, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite provided a visible image of Bailu in the Philippine Sea. The storm appeared somewhat elongated.
More public and private resources than ever are being directed to protecting and preserving aquatic ecosystems and watersheds. Whether mandated for land development, farming or in response to the growing severity and number of natural disasters - scientists from the Academy of Natural Sciences of Drexel University found evidence that decades of watershed restoration and mitigation projects have taken place, but their impact is mostly perceived; data is relatively undocumented -- or simply missing.
