Enhanced NMR reveals chemical structures in a fraction of the time Posted: 18 Jan 2019 11:55 AM PST Researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases. |
Specific cognitive deficits in individuals with spinal cord injury Posted: 18 Jan 2019 10:00 AM PST A multidisciplinary team of researchers has identified specific cognitive deficits in individuals with spinal cord injury (SCI). Their findings support the theory of accelerated aging after SCI, and have important implications for further research. |
Does being bilingual make children more focused? Study says no Posted: 18 Jan 2019 09:30 AM PST Bilingual children do not have more advantages than monolingual children when it comes to executive function, which includes remembering instructions, controlling responses, and shifting swiftly between tasks. |
Air pollution increases ER visits for breathing problems Posted: 18 Jan 2019 09:30 AM PST As levels of ozone and fine particulate pollution (PM2.5) rise, more patients end up in the ER with breathing problems, according to the largest US study of air pollution and respiratory emergency room visits of patients of all ages. |
Placentas adapt when mothers have poor diets or low oxygen during pregnancy Posted: 18 Jan 2019 09:30 AM PST Researchers have discovered the placenta regulates how much oxygen and nutrients it transports to babies during challenging pregnancies in the first study of its kind. The placenta is one of the least understood human organs and it is notoriously difficult to study. This new research focused on analyzing the placental mitochondria and it is hoped the new findings could lead to tests to determine whether a mother's placenta is functioning properly. |
Synaptic logic for connections between two brain hemispheres Posted: 18 Jan 2019 09:30 AM PST Researchers have developed a new combination of technologies that allows them to identify the functional properties of individual synapses that link the two hemispheres and determine how they are arranged within a neuron's dendritic field. |
'Happiness' exercises can boost mood in those recovering from substance use disorder Posted: 18 Jan 2019 09:30 AM PST Brief, text-based, self-administered exercises can significantly increase in-the-moment happiness for adults recovering from substance use disorders, report researchers. |
Fighting deadly drug resistant bacteria in intestines with new antibiotic Posted: 18 Jan 2019 09:29 AM PST Clostridium difficile infection (CDI) is a potentially deadly infection in the large intestine most common in people who need to take antibiotics for a long period of time, particularly in Australia's ageing population. But when doses of a new antibiotic called Ramizol were given to hamsters infected with a lethal dose of the bacteria, a significant proportion of hamsters survived the infection. |
Poor sleep and heart-related death Posted: 18 Jan 2019 08:08 AM PST Elderly men who experience extended episodes of interrupted breathing while asleep have a high risk of heart problems. Research shows for the first time that poor blood oxygenation is a good indicator of the chance of heart-related death, which cannot be attributed to sleep apnoea alone. |
Killer blows? Knockout study of pair of mouse MicroRNA provides cancer insight Posted: 18 Jan 2019 08:08 AM PST Researchers used knockout mouse models created by gene editing to reveal that the miRNA miR-146b, like miR-146a, is involved in the development of cancers, with them having similar but not identical effects. The knockout mice should help in the fight against cancers involving miRNA dysregulation. |
How musicians communicate non-verbally during performance Posted: 18 Jan 2019 08:08 AM PST Scientists have discovered a new technique to examine how musicians intuitively coordinate with one another during a performance, silently predicting how each will express the music. |
Short bouts of stairclimbing throughout the day can boost health Posted: 18 Jan 2019 08:08 AM PST It just got harder to avoid exercise. A few minutes of stair climbing, at short intervals throughout the day, can improve cardiovascular health, according to new research. |
Exposure to chemicals during pregnancy is not associated with an increase in blood pressure Posted: 18 Jan 2019 08:08 AM PST Exposure to certain chemicals such as phthalates, parabens or Bisphenol A could be associated with a decrease in blood pressure during pregnancy. |
Posted: 18 Jan 2019 08:08 AM PST Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips -- in a sense as a 'hand-knitted' unique specimen. The properties of the molecules can be monitored in real time while they are being produced. The research results have just been published in Nature Communications. |
New therapeutic avenue in the fight against chronic liver disease Posted: 18 Jan 2019 08:08 AM PST A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced a novel targeted drug delivery system in the fight against cancer. |
Potential biotech and health applications with new knowledge on bacteria and viruses Posted: 18 Jan 2019 06:59 AM PST New research to better understand how bacteria and their viruses interact and evolve will enable future studies to exploit the use of bacteria and their viruses for potential biotechnology and health applications. |
Home-based hypertension program produces 'striking' results Posted: 18 Jan 2019 05:32 AM PST Pilot study finds that an innovative care-delivery program helped 81 percent of participants achieve blood pressure control in seven weeks. |
Violence in PG-13 rated movies not linked to violence in US society Posted: 18 Jan 2019 05:32 AM PST New research suggests that policy makers should remain focused on issues that have been demonstrated to impact criminal behavior, such as family environment, mental health, poverty and education. |
Gene therapy promotes nerve regeneration Posted: 18 Jan 2019 05:31 AM PST Researchers have shown that treatment using gene therapy leads to a faster recovery after nerve damage. By combining a surgical repair procedure with gene therapy, the survival of nerve cells and regeneration of nerve fibers over a long distance was stimulated. The discovery is an important step towards the development of a new treatment for people with nerve damage. |
Frailty could make people more susceptible to dementia Posted: 17 Jan 2019 04:27 PM PST New research suggests that frailty makes older adults more susceptible to Alzheimer's dementia, and moderates the effects of dementia-related brain changes on dementia symptoms. The findings suggest that frailty should be considered in clinical care and management of Alzheimer's dementia. |
Salad, soda and socioeconomic status: Mapping a social determinant of health in Seattle Posted: 17 Jan 2019 02:52 PM PST Seattle residents who live in waterfront neighborhoods tend to have healthier diets compared to those who live along Interstate-5 and Aurora Avenue, according to new research on social disparities. The study used local data to model food consumption patterns by city block. Weekly servings of salad and soda served as proxies for diet quality. |
Bioethicists call for oversight of consumer 'neurotechnologies' with unproven benefits Posted: 17 Jan 2019 02:52 PM PST The marketing of consumer 'neurotechnologies' can be enticing: apps that diagnose a mental state, and brain devices that improve cognition or 'read' one's emotional state. However, many of these increasingly popular products aren't fully supported by science and have little to no regulatory oversight, which poses potential health risks to the public. Two bioethicists suggest the creation of a working group that would further study, monitor, and provide guidance for this growing industry -- which is expected to top $3 billion by 2020. |
Scientists learn how common virus reactivates after transplantation Posted: 17 Jan 2019 11:21 AM PST A new study challenges long-held theories of why a common virus -- cytomegalovirus, or CMV -- can reactivate and become a life-threatening infection in people with a compromised immune system, including blood cancer patients undergoing bone marrow transplantation. |
