Scientists at Tokyo Institute of Technology (Tokyo Tech) developed a new methodology that allows researchers to assess the chemical composition and structure of metallic particles with a diameter of only 0.5 to 2 nm. This breakthrough in analytical techniques will enable the development and application of minuscule materials in the fields of electronics, biomedicine, chemistry, and more.
Boston, MA - Children in low- and middle-income countries (LMICs) are receiving an average of 25 antibiotic prescriptions during their first five years of life, an excessive amount that could harm the children's ability to fight pathogens as well as increase antibiotic resistance worldwide, according to a new study from the Swiss Tropical and Public Health Institute (Swiss TPH) and Harvard T.H. Chan School of Public Health.
A new approach to trapping light in artificial photonic materials by a City College of New York-led team could lead to a tremendous boost in the transfer speed of data online.
Research into topological photonic metamaterials headed by City College physicist Alexander B. Khanikaev reveals that long-range interactions in the metamaterial changes the common behavior of light waves forcing them to localize in space. Further, the study shows that by controlling the degree of such interactions one can switch between trapped and extended (propagating) character of optical waves.
A novel technological approach developed by researchers at Baylor College of Medicine expands from two to six the number of molecular pathways that can be studied simultaneously in a cell sample with the dual luciferase assay, a type of testing method commonly used across biomedical fields.
HAMILTON, ON, Dec. 13, 2019 - A team of researchers at McMaster University has developed a self-cleaning surface that can repel all forms of bacteria, preventing the transfer of antibiotic-resistant superbugs and other dangerous bacteria in settings ranging from hospitals to kitchens.
The new plastic surface - a treated form of conventional transparent wrap - can be shrink-wrapped onto door handles, railings, IV stands and other surfaces that can be magnets for bacteria such as MRSA and C. difficile.
If healthcare providers could accurately predict how their services would be used, they could save large sums of money by not having to allocate funds unnecessarily. Deep learning artificial intelligence models can be good at predicting the future given previous behaviour, and researchers based in Finland have developed one that can predict when and why elderly people will use healthcare services.
PROVIDENCE, R.I. [Brown University] -- A team of Brown University researchers has used a brain-computer interface to reconstruct English words from neural signals recorded in the brains of nonhuman primates. The research, published in the journal Nature Communications Biology, could be a step toward developing brain implants that may help people with hearing loss, the researchers say.
When proteins in the brain form deposits consisting of insoluble aggregates, diseases such as Alzheimer's or Parkinson's can occur. Now a research team has come a step closer to understanding this process.
In Parkinson's disease the alpha-synuclein (α-synuclein) protein forms aggregates leading to impaired brain function and the development of the disease.
In 2015, the first commercial nanopore DNA sequencing device was introduced by Oxford Nanopore Technologies. Based on a synthetically engineered transmembrane protein, nanopore sequencing allows long DNA strands to be channelled through the central lumen of the pore where changes in the ionic current work as a sensor of the individual bases in the DNA. This technique was a key milestone for DNA sequencing and the achievement was only made possible after decades of research.
DURHAM, N.C. -- Researchers at Duke University have engineered a bandage that captures and holds a pro-healing molecule at the site of a bone break to accelerate and improve the natural healing process.
In a proof-of-principle study with mice, the bandage helped to accelerate callus formation and vascularization to achieve better bone repair by three weeks.
The research points toward a general method for improving bone repair after damage that could be applied to medical products such as biodegradable bandages, implant coatings or bone grafts for critical defects.
Pooled analysis of three phase 1 and 2 clinical trials published online ahead of print in the journal Lancet Oncology show that the drug entrectinib is effective and well-tolerated against advanced ROS1 and NTRK fusion-positive non-small cell lung cancers (NSCLC). Results of the trials STARTRK-1 (NCT02097810), STARTRK-2 (NCT02568267), and ALKA, show 77 percent response rate to entrectinib in 53 patients with ROS1+ NSCLC, with a median progression-free survival of 19 months and a median duration of response of 24.6 months.
A team of scientists from the Advanced Manufacturing Technologies Center of the National Technology Initiative (NTI) of Peter the Great St.Petersburg Polytechnic University (SPbPU) (head -- Prof. A.I. Borovkov, the Vice-rector for Advanced Projects of Peter the Great St. Petersburg Polytechnic University) developed a mathematical model of an "endoprosthesis-skeleton" system. Special attention was paid to the geometry and internal structure of hip bones.
Since the 1950s at least, researchers have speculated that the brain is a kind of computer in which neurons make up complex circuits that perform untold numbers of calculations every second. Decades later, neuroscientists know that these brain circuits exist, yet technical limitations have kept most details of their computations out of reach.
Baby boys who are born small for their gestational age are at increased risk of having fertility problems in adulthood, according to research published today (Friday) in Human Reproduction , one of the world's leading reproductive medicine journals.
The recovery of pine marten in Ireland and Britain is reversing native red squirrel replacement by invasive grey squirrels, according to new research presented at the British Ecological Society's annual meeting in Belfast today.
Researchers at Queens University, Belfast and National Museums Northern Ireland have found red squirrels are responding positively to the increased presence of pine martens across Northern Ireland. So, where pine martens occur, it increases the chances of red squirrels occurring, simultaneously reducing the likelihood of grey squirrels being present.
