When electronics need their own power sources, there are two basic options: batteries and harvesters. Batteries store energy internally, but are therefore heavy and have a limited supply. Harvesters, such as solar panels, collect energy from their environments. This gets around some of the downsides of batteries but introduces new ones, in that they can only operate in certain conditions and can't turn that energy into useful power very quickly.
DALLAS – April 21, 2020 – Brain cancer patients in the coming years may not need to go under the knife to help doctors determine the best treatment for their tumors.
A new study by UT Southwestern shows artificial intelligence can identify a specific genetic mutation in a glioma tumor simply by examining 3D images of the brain – with more than 97 percent accuracy. Such technology could potentially eliminate the common practice of pretreatment surgeries in which glioma samples are taken and analyzed to choose an appropriate therapy.
It is no secret that genetic factors play a role in determining whether children have neurodevelopmental disorders. Maternal exposure to drugs and viral or bacterial illnesses can be detrimental too.
However, a recent epidemiological survey of approximately 6 million people worldwide has revealed that advanced paternal age is associated with the development of neurodevelopmental disorders. In other words, the older the parent, the increased risk a child has of developing disorders such as autism, ADHD and other learning disabilities.
When an earthquake or other natural disaster strikes, government relief agencies, insurers and other responders converge to take stock of fatalities and injuries, and to assess the extent and cost of damage to public infrastructure and personal property.
A large marine heatwave would double the rate of the climate change impacts on fisheries species in the northeast Pacific by 2050, says a recently released study by researchers from the University of British Columbia and University of Bern.
In 2013, a large marine heatwave, nicknamed the 'Blob', occurred in the northeast Pacific Ocean. From the coast of Alaska to Baja California, the Blob had a significant impact on the marine life and fisheries in this region; an impact that lasted for several years.
Chinese researchers have developed a pulsed optically pumped (POP) atomic clock with a frequency stability of 4.7 × 10-15 at 104 seconds based on a new design.
The achievement is noteworthy because atomic clocks - often considered the most stable frequency standard for timekeeping - are crucial components in global navigation systems and international communication services, and frequency stability is key to their accuracy.
POP atomic clocks are an important research focus because they are lightweight and show excellent frequency stability.
Some solid tumors have a very high growth rate, which often leads to a lack of vascularization due to the impossibility to develop, at the same time, the blood vessels that accompany and nourish it. The team of Dr. Cristina Muñoz Pinedo, from the Bellvitge Biomedical Research Institute (IDIBELL) and the Faculty of Medicine and Health Science of the University of Barcelona (UB), with the collaboration of the Catalan Institute of Oncology (ICO), has studied how tumor cells respond to this lack of nutrients.
Scientists have identified a key step in the process that leads to leaky vessels and harmful swelling in eye diseases, according to a new study published today in eLife.
The discovery could lead to improved treatments for diseases such as age-related macular degeneration and diabetic retinopathy. These diseases cause leaky blood vessels to grow in the eyes, leading to harmful swelling and progressive vision loss.
Researchers from the Biophysics and Bioengineering Unit of the University of Barcelona have created a non-invasive low-cost ventilator, to support patients with respiratory diseases in areas with limited means. Researchers published the results of the study in the European Respiratory Journal together with open source technical features to build it.
Experts at the University of Tokyo have identified a new protein in the pathway that leads
to Alzheimer's disease. Researchers used the "molecular scissors" of CRISPR/Cas9 to
search for new genes related to the neurodegenerative disease.
The exact causes of Alzheimer's disease remain unknown, but one of the most well-
supported theories focuses on a protein called amyloid beta. Aggregation, or clumping
together, and the depositing of two proteins, amyloid beta and tau, throughout a patient's
brain are a signature of Alzheimer's disease.
Sweet food is even sweeter when you drink coffee. This is shown by the result of research from Aarhus University. The results have just been published in the scientific journal Foods.
Coffee lovers with a penchant for dark chocolate now have a scientific explanation for why the two are a perfect match. A study from Aarhus University shows that coffee makes you more sensitive to sweetness.
Would you like to be able to find out which antibiotic combination works best for a particular patient? And do it in just 12 or maybe even 6 hours, in a point-of-care? Or maybe search for antibodies in thousands of samples at a time? It's all possible with a new device invented by scientists from IPC PAS. It is cheap, fast & reliable, it can replace strip tests and give patients a better chance to fight disease.
When it comes to increasing electric storage efficiency and electric breakdown strength -- the ability of an electrical system to operate at higher voltage and temperatures with great efficiency -- increasing one traditionally has led to a decrease in the other. Penn State researchers, led by Qiming Zhang, distinguished professor of electrical engineering, recently developed a scalable method that relies on engineered materials to increase both properties.
PHILADELPHIA (April 21,2020) - Substance use by youth remains a significant public health concern. While social media provides youth the opportunity to discuss and display substance use-related beliefs and behaviors, little is known about how posting drug-related content, or viewing posted content influences the beliefs and behaviors of youth relative to substance use.
An interdisciplinary team of researchers from the University of Lincoln, UK, and York University, Canada, investigated how the global trend towards urbanisation has contributed to the rise in the total number of disease outbreaks per decade since the 1980s.
