Artificial intelligence researchers at North Carolina State University have improved the performance of deep neural networks by combining feature normalization and feature attention modules into a single module that they call attentive normalization (AN). The hybrid module improves the accuracy of the system significantly, while using negligible extra computational power.
Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world's smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as super-resolution imaging.
A medical robotic hand could allow doctors to more accurately diagnose and treat people from halfway around the world, but currently available technologies aren't good enough to match the in-person experience.
Researchers report in Science Advances that they have designed and produced a smart electronic skin and a medical robotic hand capable of assessing vital diagnostic data by using a newly invented rubbery semiconductor with high carrier mobility.
New Rochelle, NY, September 16, 2020—A novel taxonomic approach to obesity prevention using existing U.S. obesity prevention studies is highlighted in a special supplement of the peer-reviewed journal Childhood Obesity.
A research team from Caltech and the UCLA Samueli School of Engineering has demonstrated a promising way to efficiently convert carbon dioxide into ethylene -- an important chemical used to produce plastics, solvents, cosmetics and other important products globally.
Vaccines have curtailed the spread of several infectious diseases, such as smallpox, polio and measles. However, vaccines against some diseases, including HIV-1, influenza and malaria, don't work very well, and one reason could be the timing of antigen and adjuvant presentation to the immune system. Now, researchers reporting in ACS Central Science developed an injectable hydrogel that allows sustained release of vaccine components, increasing the potency, quality and duration of immune responses in mice.
PITTSBURGH, Sept. 16, 2020 - The slight decline in drug overdose deaths in 2018 coincided with changing Chinese regulations on a powerful type of opioid, rather than the result of U.S. efforts to curb the overdose epidemic, a University of Pittsburgh Graduate School of Public Health analysis revealed today in the journal Addiction.
BINGHAMTON, NY -- BINGHAMTON, NY -- Biosensors that are wearable on human skin or safely used inside the body are increasingly prevalent for both medical applications and everyday health monitoring. Finding the right materials to bind the sensors together and adhere them to surfaces is also an important part of making this technology better. A recent study from Binghamton University, State University of New York offers one possible solution, especially for skin applications.
WASHINGTON, September 15, 2020 -- Nanogenerators capable of converting mechanical energy into electricity are typically made from metal oxides and lead-based perovskites. But these inorganic materials aren't biocompatible, so the race is on to create natural biocompatible piezoelectric materials for energy harvesting, electronic sensing, and stimulating nerves and muscles.
PULLMAN, Wash. - Researchers in recent years have demonstrated the health benefits of soy, linking its consumption to reduced risk of cardiovascular disease, obesity, cancer and improved bone health.
Now, WSU researchers are hoping to use the health benefits of the popular legume to improve post-operative treatment of bone cancer.
Osaka, Japan - How do you turn on and off an ultra-small component in advanced technologies? You need an actuator, a device that transmits an input such as electricity into physical motion. However, actuators in small-scale technologies to date have critical limitations. For example, if it's difficult to integrate the actuator into semiconductor electronics, real-world applications of the technology will be limited. An actuator design that operates quickly, has precise on/off control, and is compatible with modern electronics would be immensely useful.
Researchers at the Babraham Institute have used their understanding of cellular signalling to highlight a pitfall in an emerging treatment for cancer and inflammation. A new review just published in Biochemical Society Transactions summarises the researchers' current knowledge, which includes details of their research published in Nature Communications earlier this year. Developing awareness around these findings will prevent wasted effort and resource being spent on further drug discovery research relating to this drug target by commercial pharmaceutical companies.
There are billions of bacteria around us and in our bodies, most of which are harmless or even helpful. But some bacteria such as E. coli and salmonella can cause infections. The ability to swim can help bacteria to seek out nutrients or to colonize parts of the body and cause infection.
Researchers from the Faculty of Health and Medical Sciences, University of Copenhagen, have now provided fundamental insight into how this bacterial movement is powered, solving a yearlong mystery within the field.
The combined effects of the body's microbiota working together with COVID-19 in the lungs could explain the severity of the disease in people with obesity and diabetes, according to a new article published today in eLife.
The review offers important mechanistic insights into why people with obesity and diabetes seem to be at increased risk of developing severe acute respiratory syndrome (SARS) after infection with the COVID-19 virus, and more often require hospitalisation and ventilation.
