Low-cost, fly footpad-like adhesive structure capable of repeated attachment/detachment
NIMS, HUE and HUSM have succeeded in developing a method of easily and cheaply producing an adhesive structure capable of repeated attachment and detachment. The design of this structure was inspired by the adhesive spatula-shaped hairs (setae) found on the footpads of flies, while the method of producing it was hinted at by seta formation in fly pupae. These environmentally sound technologies...
LSU Health study explains multipronged SARS-CoV-2 attack and widespread COVID-19 infection
A study of a gateway receptor for SARS-CoV-2 led by Walter J. Lukiw, PhD, Professor of Neuroscience, Neurology and Ophthalmology at LSU Health New Orleans' Neuroscience Center of Excellence and School of Medicine, may help explain the wide variety of symptoms and organs involved with SARS-CoV-2 infection and COVID-19. The results suggest that a multi-organ infection with SARS-CoV-2 may be via the...
Maternal insecticide use during pregnancy and neonatal jaundice
Association between pesticide usage during pregnancy and neonatal hyperbilirubinemia requiring treatment: The Japan Environment and Children's study.
NASA sees wind shear still battering tropical storm Iselle
NASA infrared imagery shows wind shear continued to batter Tropical Storm Iselle in the Eastern Pacific Ocean for the second day.
NASA Terra Satellite examines Tropical Storm Hernan's relocated center
NASA infrared imagery revealed a burst of strength in Tropical Storm Hernan, located over the Gulf of California. At 12:30 a.m. EDT, NOAA's National Hurricane Center or NHC noted that recent satellite-based wind data indicated Hernan was located northeast of previous estimates.
NASA Terra Satellite sees development of Tropical Storm Maysak
NASA infrared imagery revealed several areas of strong thunderstorms around the center of the recently organized Tropical Storm Maysak.
NASA-NOAA satellite nighttime imagery tracks Tropical Depression Laura over US
A new animation of nighttime imagery from NASA-NOAA's Suomi NPP satellite followed the path of former Hurricane Laura from its landfall in southwestern Louisiana to its movement over the Mississippi Valley.
Natural disasters must be unusual or deadly to prompt local climate policy change
Natural disasters alone are not enough to motivate local communities to engage in climate change mitigation or adaptation, a new study from Oregon State University found. Rather, policy change in response to extreme weather events appears to depend on a combination of factors, including fatalities, sustained media coverage, the unusualness of the event and the political makeup of the community.
New analysis reveals where marine heatwaves will intensify fastest
High-resolution ocean modelling has found the world's strongest ocean currents, which play key roles in fisheries and ocean ecosystems, will experience more intense marine heatwaves than the global average over the coming decades.
New malaria transmission patterns emerge in Africa
An international study reveals how future climate change could affect malaria transmission in Africa over the next century.
New palliative care model shown to reduce costs without compromising on quality of care
Findings from a large-scale clinical trial testing a new palliative care model have shown to be lower cost, viewed positively by patients and their carers while showing no difference in patient-reported outcomes when compared with standard care.
New study examines long-term aesthetic outcomes of implant-based breast reconstruction
Breast reconstruction is an important option for women undergoing mastectomy, and a two-stage approach using implants is by far the most common reconstruction technique. Thousands of women undergo this procedure every year - despite the conventional wisdom among many surgeons that the results of implant-based breast reconstruction don't hold up over the long term.
Nurses burned out and want to quit
A survey of nurses caring for children with heart problems has revealed that more than half are emotionally exhausted. The analysis, presented today at ESC Congress 2020, also found that good working environments were linked with less burnout. "Nurses' wellbeing is central to ensuring the best outcomes for patients," said study author Dr. Annamaria Bagnasco of the University of Genoa, Italy.
Observation charge accumulation at nanocavity on plasmonic photocatalyst
Understanding where the plasmonic charge accumulated at catalysts surface and how to improve local charge density at catalytic sites is promising for solar energy conversion. Scientists find plasmonic charge accumulation at nanocavity of Au nanoparticle dimer/TiO2 photocatalyst at the single particle level. Such charge accumulation at catalytic sites can significantly accelerate the water...
Physiological test for autism proves effective independent of co-occurring conditions
Developing a physiological test for diagnosing autism spectrum disorder (ASD), one that measures certain components in the blood, has the potential to be a paradigm shift for diagnosing ASD. However, the large heterogeneity of how ASD affects individuals has long been viewed as a key obstacle to the development of such a test. Research conducted at Rensselaer Polytechnic Institute, and published...
Plant scientists study the interaction of heat stress responses in corn
A new study shows how two responses in separate locations inside plant cells work in concert to help corn plants respond to heat stress. The research was made possible by the Enviratron, an innovative plant sciences facility at Iowa State University that utilizes a robotic rover and highly controlled growth chambers.
Portland State lab finds finds new levels of detail about key membrane proteins
Portland State University researchers used advanced electron microscopy to create a 3-D reconstruction of a membrane protein at an unprecedented level of resolution, setting the stage for the development of drugs that could target the protein more effectively to treat a variety of diseases.
Preventing infection, facilitating healing: New biomaterials from spider silk
New biomaterials developed at the University of Bayreuth eliminate risk of infection and facilitate healing processes. These nanostructured materials are based on spider silk proteins. They prevent colonization by bacteria and fungi, but at the same time proactively assist in the regeneration of human tissue. They are therefore ideal for implants, wound dressings, prostheses, contact lenses, and...
Research brief: Researchers 3D print lifelike heart valve models
Researchers from the University of Minnesota, with support from Medtronic, have developed a groundbreaking process for multi-material 3D printing of lifelike models of the heart's aortic valve and the surrounding structures that mimic the exact look and feel of a real patient.
Researchers dramatically downsize technology for fingerprinting drugs and other chemicals
As new infectious diseases emerge and spread, one of the best shots against novel pathogens is finding new medicines or vaccines. But before drugs can be used as potential cures, they have to be painstakingly screened for composition, safety and purity, among other things. Thus, there is an increasing demand for technologies that can characterize chemical compounds quickly and in real time.
Researchers explore how retail drone delivery may change logistics networks
Three UT Dallas researchers found that last-mile delivery networks will become more decentralized and the delivery speed of the drones will increase as the technology matures.
Researchers find potential to make brain cancers in children respond better to treatment
Research has identified a small molecule compound that can activate the Wnt pathway in non-Wnt subtypes of medulloblastoma, making these aggressive forms of cancer more responsive to therapies. The work also found the Wnt pathway, which has historically been considered cancer-promoting, to function as a cancer inhibitor in certain contexts.
Scientists listed the main approaches to the treatment of coronavirus
Researchers from Sechenov University together with Russian and Iranian colleagues described currently known approaches to the treatment of SARS-CoV-2 infection. In the paper published in Journal of Molecular Medicine, they wrote about how different groups of drugs worked and how promising each approach was.
Structural colors from cellulose-based polymers
A surface displays structural colors when light is reflected by tiny, regular structural elements in a transparent material. Researchers have now developed a method to make structural colors from cellulose-based polymers by using coated droplets that exist in a surrounding fluid--so-called liquid marbles. The system readily responds to environmental changes, which makes it interesting for...
