After gaining world attention by 'unboiling' egg protein, Flinders University scientists have now used an Australian-made novel thin film microfluidic device to manipulate Beta-lactoglobulin (β-lactoglobulin), the major whey protein in cow's, sheep's and other mammals milk.
The so-called Vortex Fluidic Device has previously been used in an array of experiments to successfully 'un-boil' egg protein and even break the molecular bonds of one of the world's hardest material, carbon nanotubes.
As Xi'an Jiaotong-Liverpool University researchers completed their research on coloured architectural concrete, they found a surprising result--green pigmented cement had impurities that produced porous, poor quality concrete. Meanwhile, red and blue pigments had little effect.
The research was conducted by Mehreen Heerah, a graduate of XJTLU's Department of Civil Engineering, Dr Graham Dawson of XJTLU's Department of Chemistry, and Isaac Galobardes of Mohammed VI Polytechnic University.
Alexandria, Va., USA - Hiba Nasir, Wayzata High School, Plymouth, Minn., presented the poster "Oral-Health Impact Profile 5: Analyzing A Private Practice Adult Population's Distribution" at the virtual 99th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 50th Annual Meeting of the American Association for Dental Research (AADR) and the 45th Annual Meeting of the Canadian Association for Dental Research (CADR), on July 21-24, 2021.
New research from the University of Otago debunks a long-held belief about our ancestors' eating habits.
For more than 60 years, researchers have believed Paranthropus, a close fossil relative of ours which lived about one to three million years ago, evolved massive back teeth to consume hard food items such as seeds and nuts, while our own direct ancestors, the genus Homo, is thought to have evolved smaller teeth due to eating softer food such as cooked food and meats.
Elderly patients with neurological conditions are significantly more likely to develop delirium shortly after they are hospitalised.
A new study has discovered that a delayed transfer to a hospital floor is associated with greater short-term risk of delirium among patients aged 65 and over, and for those who arrive to the Emergency Department (ED) on days with higher risk of prolonged lengths of stay - found to be Sunday and Tuesday.
Electromagnetic (EM) waves in the terahertz (THz) regime contribute to important applications in communications, security imaging, and bio- and chemical sensing. Such wide applicability has resulted in significant technological progress. However, due to weak interactions between natural materials and THz waves, conventional THz devices are typically bulky and inefficient. Although ultracompact active THz devices do exist, current electronic and photonic approaches to dynamic control have lacked efficiency.
In the evolving field of cancer biology and treatment, innovations in organ-on-a-chip microdevices allow researchers to discover more about the disease outside the human body. These organs-on-chips serve as a model of the state an actual cancer patient is in, thus allowing an opportunity to finding the correct treatment before administering it to the patient. At Texas A&M University, researchers are pushing these devices to new levels that could change the way clinicians approach cancer treatment, particularly ovarian cancer.
St. Jude Children's Research Hospital investigators have demonstrated that comprehensive genomic sequencing of all pediatric cancer patients is feasible and essential to capitalize on the lifesaving potential of precision medicine. Results from the St. Jude Genomes for Kids study appear online today in the journal Cancer Discovery.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic fields which stably trapped and lifted a small polystyrene ball from a reflective surface. Although their technique employs a method similar to laser trapping in biology, adaptable to a wider range of particle sizes and materials.
A dust storm that engulfed Mars in 2018 destroyed a vortex of cold air around the planet's south pole and brought an early spring to the hemisphere. By contrast, the storm caused only minor distortions to the polar vortex in the northern hemisphere and no dramatic seasonal changes. Dr Paul Streeter of The Open University's Faculty of Science, Technology, Engineering and Mathematics will present the work today (23 July) at the virtual National Astronomy Meeting (NAM 2021).
In the suburbs of Sydney, Australia, sulphur-crested cockatoos routinely loot lidded household waste bins to scavenge for food. In a new study, researchers document the emergence and geographic spread of innovative bin-opening behaviors in urban parrot populations, revealing the presence of a complex social learning culture in these birds. What's more, this behavior appears to have emerged as a direct response to land-use change and urbanization, demonstrating how animal cultures could allow for local adaptation of urban animal populations in the Anthropocene.
Based on the analysis of marsquakes recorded by NASA's InSight mission, the structure of Mars's crust has now been determined in absolute numbers for the first time. Beneath the InSight landing site, the crust is either approximately 20 or 39 kilometres thick. That is the result of an international research team led by geophysicist Dr Brigitte Knapmeyer-Endrun at the University of Cologne's Institute of Geology and Mineralogy and Dr Mark Panning at Jet Propulsion Laboratory, California Institute of Technology (Caltech).
LONDON, 22 July 2021 - DeepMind today announced its partnership with the European Molecular Biology Laboratory (EMBL), Europe's flagship laboratory for the life sciences, to make the most complete and accurate database yet of predicted protein structure models for the human proteome. This will cover all ~20,000 proteins expressed by the human genome, and the data will be freely and openly available to the scientific community.
As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?
A new Yale study suggests that, in a sense, mammals dream about the world they are about to experience before they are even born.
A research team led by Dr Aixin YAN, Associate Professor from the Research Division for Molecular & Cell Biology, Faculty of Science, in collaboration with Honorary Clinical Professor Patrick CY WOO from the Department of Microbiology, Li Ka Shing Faculty of Medicine, the University of Hong Kong (HKU), reported the development of a transferrable and integrative type I CRISPR-based platform that can efficiently edit the diverse clinical isolates of Pseudomonas aeruginosa, a superbug capable of infecting various tissues and organs and a major source of nosocomial infections.
