New Radioactive Tracer Lights Up Brain’s Connections to Study Disorders

admin

Various brain disorders change the physical nature of synapses in the brain, but this fact has been useless in clinical practice because evaluating these changes could only be done once the patient passes away. Now researchers at Yale University have developed a technique, published on in journal Science Translational Medicine, that relies on PET (positron emission tomography) and a novel tracer to image billions of synapses at the same time. Their radioactive tracer was engineered to grab onto the synaptic vesicle glycoprotein 2A (SV2A), which after injection can be viewed on a PET scanner.…

The Death of Cubicles: Engineers Create the First Mobile Workstations

admin

Got a smelly weirdo sitting next to you at work? Need a place to stick an intern? Well it looks like cubicle life as we know it is about to change. If some cutting-edge companies have their way, we may all soon be working from mobile workstations. What those spaces will look like all depends on the designer. Here’s a look at the most notable designs: • Michiel van der Kley’s Globus folds up into a globe and unfolds into a desk and a chair. • The ScooterDesk by Utilia may look uncomfortable, but its barstool design with…

3D Bioprinting

admin

In the field of medical science, technology is flourishing. With the development, more lives are saved, and we are now reaching the period of bombarding innovations. Cancer will eventually be cured, heart diseases are no longer a treat, and damaging flus are not a topic that come into our mind. One of the technology innovations is 3D bio-printing. Every year, hundreds and thousands of people are in the list of waiting for the donations of organs, like kidneys, hearts, and livers. However, the lack of donors is a severe problem…

New Mobile App Lets Scientists Nab Data Anywhere on Earth

admin

To our graduate student readers: As if constant emails from your boss weren’t enough,  soon you’ll have no excuse to avoid the “got any data?” question—even when you’re out in the field. A new mobile app now lets researchers collect and analyze data from anywhere in the world, using their cell phones. It’s not all bad: The software could help you unload some of your work by allowing citizen scientists to snap pictures from their own backyards, and contribute them to research projects. The software, called EpiCollect, is especially useful for…

Harmless “T-Ray” Vision Sees Through Boxes, Walls and Skin

admin

Call it the “X-ray vision” app: In several years, smartphones could come equipped with a microchip that lets users peer through boxes, walls and other objects. Rather than dangerous X-rays, however, the chip beams out waves in the harmless terahertz frequency, a little-used portion of the electromagnetic spectrum between microwaves and far-infrared. Terahertz generators historically have been bulky, expensive affairs. But now Caltech researchers have succeeded in crafting terahertz-emitting silicon chips that are smaller than a dime using a standard, inexpensive electronics manufacturing technique. The researchers harnessed an array of…

A Laser Modified by Blood to Look at Tissues from Inside

admin

Infrared, ultraviolet, and visible light are commonly used to visualize tissues in a variety of ways, but the light is typically not coherent, poorly focused, and not very bright. Researchers at the University of Michigan have been working on a way of getting blood to act like a laser, revealing medically relevant information from within the body. Recently presented at the Conference on Lasers and Electro-Optics in San Jose, California, the research involved using indocyanine green dye that cardiologists, ophthalmologists, and other doctors are well familiar with. The dye was…

Machine Learning for Text Classification

admin

Machine Learning for Text Classification Machine learning can used to classified different category of texts, by using various classifiers. The common machine learning classifiers are support vector machine, Naive Bayes and even ensemble models, such as stochastic gradient descent. Besides, deep learning neural network is also a choice for the text classification. Those classifiers and neural network enable us to category the text and even to find the author for the specific text. The general idea is that we input the text of specific category or author, and then we…

AI

admin

As our investment in technology is increasing, our world is updated by new technologies that benefit our daily life. In some countries, robots are beginning to deliver food and services, work in factories, and do things that human cannot do. Soon, we may see human-like robots talking to humans as if they have real brains and intellectual ability, or mimicking our facial impressions as if they have real feelings of satisfaction and anger. AI is on its way to our life. AI is short for Artificial Intelligence, which is defined…

NEW SOLID OXIDE FUEL CELL TECHNOLOGY

admin

Scientists are tirelessly working on sources of alternative energy so that we can have a better substitute for fossil fuels in near future. We know that sunlight, wind and geothermal sources of energy are better for everyone. But they also need efficient fuel cells for better utilization of power. Solid oxide fuel cells (SOFCs) seem promising enough for both stationary and mobile applications. Stationary use can cover residential applications to power plants. Mobile applications contain energy for ships at sea and in space, as well as for automobiles. Another advantage of the…
