Researchers at the National Institute of Standards and Technology (NIST) have made one of the highest-performance cameras ever composed of sensors that count single photons, or particles of light.
With more than 1,000 sensors, or pixels, NIST's camera may be useful in future space-based telescopes searching for chemical signs of life on other planets, and in new instruments designed to search for the elusive "dark matter" believed to constitute most of the "stuff" in the universe.
Tracking the lateral position of single cells and particles plays an important role in evaluating the efficiency of microfluidic cell focusing, separation and sorting. Traditionally, the performance of microfluidic cell separation and sorting is evaluated either by analyzing the input and collected output samples requiring extra multiple steps of off-chip analysis or the use of expensive equipment (e.g., flow cytometry), or by detecting the lateral positions of cells using an expensive high-speed imaging setup with intricate image processing algorithms or laborious manual analysis.
According to the World Health Organization, cervical cancer is the fourth most common type of cancer affecting women worldwide. Currently, early screenings of pre-cancerous tissues and vaccination have proven to be the most effective treatment strategies. However, the lack of such interventions in developing nations has led to its high occurrence. Among the South East Asian nations alone, India has the highest incidence rate of cervical cancer.
Single-wall carbon nanotubes (SWCNT) have found many uses in electronics and new touch screen devices. Carbon nanotubes are sheets of one atom-thick layer of graphene rolled up seamlessly into different sizes and shapes. To be able to use them in commercial products like transparent transistors for phone screens, researchers need to be able to easily test nanotubes for their materials properties, and the new method helps with this.
There has been a substantial increase in food production over the last 50 years, but it has been accompanied by a narrowing in the diversity of cultivated crops. New research shows that diversifying crop production can make food supply more nutritious, reduce resource demand and greenhouse gas emissions, and enhance climate resilience without reducing calorie production or requiring more land.
They are reminiscent of the "tractor beam" in Star Trek: special light beams can be used to manipulate molecules or small biological particles. Even viruses or cells can be captured or moved. However, these optical tweezers only work with objects in empty space or in transparent liquids. Any disturbing environment would deflect the light waves and destroy the effect. This is a problem, in particular with biological samples because they are usually embedded in a very complex environment.
Deep machine learning method can predict molecular wave functions and electronic properties of molecules
This algorithm could drastically speed-up future simulation efforts in the design of drug molecules or new materials
Artificial Intelligence can be used to predict molecular wave functions and the electronic properties of molecules. This innovative AI method developed by a team of researchers at the University of Warwick, the Technical University of Berlin and the University of Luxembourg, could be used to speed-up the design of drug molecules or new materials.
Scientists from Trinity College Dublin have created a suite of new biological sensors by chemically re-engineering pigments to act like tiny Venus flytraps. The sensors are able to detect and grab specific molecules, such as pollutants, and will soon have a host of important environmental, medical and security applications.
Porphyrins, a unique class of intensely coloured pigments - also known as the "pigments of life" - provide the key to this ground-breaking innovation.
ANN ARBOR--Silicon integrated circuits, which are used in computer processors, are approaching the maximum feasible density of transistors on a single chip--at least, in two-dimensional arrays.
Now, a team of engineers at the University of Michigan have stacked a second layer of transistors directly atop a state-of-the-art silicon chip.
They propose that their design could remove the need for a second chip that converts between high- and-low voltage signals, which currently stands between the low-voltage processing chips and the higher-voltage user interfaces.
New Haven, Conn. -- A new Yale study shows that some patients being treated for severe heart failure with a battery-operated pump saw significant improvement after additionally using neurohormonal blockade (NHB) drug therapy.
Researchers at the University of Illinois at Chicago report that among patients with obesity, robotic kidney transplants produce survival outcomes comparable to those seen among nonobese patients.
Their study, published in the American Journal of Transplantation, includes data collected over 10 years from more than 230 robotic-assisted kidney transplants in patients with obesity.
People with Borderline Personality Disorder are 13 times more likely to report childhood trauma than people without any mental health problems, according to University of Manchester research.
The analysis of data from 42 international studies of over 5,000 people showed that 71.1% of people who were diagnosed with the serious health condition reported at least one traumatic childhood experience.
London schoolchildren have found that some of their families' soup recipes have antimalarial properties, with the help of Imperial scientists.
Researchers from Imperial College London helped the schoolchildren test their family soup broths for activity against the malaria parasite.
Margays (Leopardus wiedii), small wild cats living in forest areas fragmented by agriculture near Campinas and Botucatu in São Paulo State, Brazil, prey on animals inhabiting nearby sugarcane plantations, such as birds and small rodents.
Even novice photographers and videographers who rely on their handheld devices to snap photos or make videos often consider their subject's lighting. Lighting is critical in filmmaking, gaming, and virtual/augmented reality environments and can make or break the quality of a scene and the actors and performers in it. Replicating realistic character lighting has remained a difficult challenge in computer graphics and computer vision.
