As a spinoff from their research aimed at fighting a specific parasite, researchers at the U.S. Department of Energy’s Argonne National Laboratory and Brandeis University may have found a way around an infectious bacterium’s natural defenses.
The high seas of Mars may never have existed. According to a new study that looks at two opposite climate scenarios of early Mars, a cold and icy planet billions of years ago better explains water drainage and erosion features seen on the planet today.
Thanks to a collaboration with the Balgrist University Hospital and University of Pittsburgh, Empa is beginning to decode the mechanics of the lower vertebrae. Researchers would like be able to reveal how wear and tear comes about on vertebral bodies and spinal disks. This would also make choosing the appropriate therapy much easier.
People who live in countries built on centuries of migration from a wide range of other countries are more emotionally expressive than people in more insular cultures, according to research led by University of Wisconsin–Madison psychology Professor Paula Niedenthal.
In this week’s Applied Physics Letters, researchers from Thailand and Japan describe the first known demonstration of 3-D cell imaging using picosecond ultrasonics, and show that picosecond ultrasonics can achieve micron resolution of single cells, imaging their interiors in slices separated by 150 nanometers. This work is a proof-of-principle that may open the door to new ways of studying the physical properties of living cells by imaging them in vivo.
Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world's most powerful digital cameras, are the largest contiguous maps created at this level of detail and will improve our understanding of dark matter's role in the formation of galaxies.
A research team at Emory University presents new research at the 2015 AAP Annual Meeting in San Antonio that suggests that early rehabilitation as well as discharges to acute rehabilitation facilities post stroke can improve neurologic outcomes. The purpose of the study was to investigate the impact of introducing a physiatrist into an acute stroke team.
The national gross domestic product (GDP) is a stronger predictor of job satisfaction than workers' personal or job-related characteristics, reports the March Journal of Occupational and Environmental Medicine, official publication of the American College of Occupational and Environmental Medicine (ACOEM).
Penn Medicine researchers found that patients who did not respond to cognitive behavioral therapy (CBT) for anxiety in childhood had more chronic and enduring patterns of suicidal ideation at 7 to 19 years after treatment. This study adds to the literature that suggests that successful CBT for childhood anxiety confers long-term benefits. The complete study is available in the Journal of the American Academy of Child & Adolescent Psychiatry.
Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.
Researchers create first mouse model of ovarian clear cell carcinoma using data from human cancer genome atlas. They show how when the genes ARID1A and PIK2CA are mutated in specific ways, the result is ovarian cancer 100 percent of the time. They show that a known drug can suppress tumor growth.
In some of the first research findings to be published from the European Space Agency’s Rosetta Mission to the comet 67P/Churyumov-Gerasimenko, scientists report this week in Science on early measurements of the comet’s subsurface temperature and production of gas from the surface of its nucleus.
Recent scientific advances have meant that eyesight can be partially restored to those who previously would have been blind for life. However, scientists at the University of Montreal and the University of Trento have discovered that the rewiring of the senses that occurs in the brains of the long-term blind means that visual restoration may never be complete.
A good night’s sleep is linked to better performance by schoolchildren in math and languages – subjects that are powerful predictors of later learning and academic success, according to a study by researchers at McGill University and the Douglas Mental Health University Institute in Montreal.
While many smokers may make quitting part of their New Year’s resolution – a new study may give some yet another reason to stop – the negative impact cigarette smoke has on chronic wounds. Despite the fact that chronic wounds cost up to $25 billion to treat annually, healthcare providers often don’t discuss smoking with their chronic wound patients. New research explores the connection between non-healing wounds and smoking – and the missed opportunities to help patients understand how their habit is hurting their ability to heal.
Ohio University researchers find that regular mental imagery exercises help preserve arm strength during 4 weeks of immobilization. The article is published in the Journal of Neurophysiology and is highlighted as part of the APSselect program.
