Researchers find new way to enhance the sensitivity of electrochemical micro-sensors
A team led by researchers at the New York University Tandon School of Engineering have found a new way of enhancing the performance of electrochemical micro-sensors. This discovery could lead to the detection of biomolecules, such as dopamine, at lower concentrations than is possible today. Their findings are described in a paper published in the journal
Biosensors and Bioelectronics.
Dopamine molecule activity in the brain is associated with important functions such as motivation, motor control, reinforcement, and reward. Researchers and clinicians commonly monitor neurotransmitter activity in the brain through electrochemical micro-sensors made of carbon. However, due to their limited sensitivity, existing micro-sensors can detect only large changes in dopamine levels. They can also record from only one site in the brain at a time.

VOTIS Subdermal Imaging Technologies And ii Ventures Announce Plans To Develop Preventative Medicine Devices To Screen For Peripheral Artery Disease In India
Emphasis on impoverished rural sector, comprising 65.53% of the national population
JERUSALEM and MUMBAI, India, Dec. 21, 2020 /PRNewswire/ VOTIS Subdermal Imaging Technologies, Ltd., an Israeli corporation, and ii Ventures Private Limited (iiV), an Indian company, announced today that they have entered into a memorandum of understanding to develop a system to screen the largely rural Indian population for peripheral artery disease (PAD). The devices, which allow for the early detection of the disease before tangible symptoms appear, will utilize the same technology that VOTIS is building into other devices intended for use in the US and Europe.

Many young aspiring scientists question if they need a Ph.D. to conduct research. Even though the conventional belief is that you need to be a doctor to succeed, a few scientists have historically managed to become famous without a doctorate. Here, Kevin Dalby - a professor of chemical biology and medicinal chemistry at The University of Texas in Austin, answers whether you need a Ph.D. to become a researcher and features a few outliers - scientists who never got their Ph.D. but became successful and even famous.
One way to think about obtaining a Ph.D. is to envision that your career as a scientist is a 12,000-foot mountain, and you are standing at the base. What you want to achieve, the discoveries you want to make, and the papers you would like to publish are all at, or near, the top of the mountain.
NSF providing critical support in COVID-19 fight
With the COVID-19 pandemic, the United States is facing one of the greatest challenges of its history. Addressing the wide-ranging impact of the pandemic requires the combined efforts of researchers across numerous scientific disciplines. As the only U.S. federal agency that supports fundamental research across all fields of science and engineering, the U.S. National Science Foundation has been an integral part of the response. The foundation has made more than 1,200 awards totaling over $200M to study multiple aspects of the pandemic. With this support, researchers have gained insight into how the virus spreads, developed improved personal protective measures, and are beginning to address the long-range mental health impact of the pandemic.
