DNA-Based Robots: Researchers Use Magnets to Control Them

Researchers have devised a magnetic control system to make tiny DNA-based robots move on demand-; and much faster than recently possible. In the journal Nature Communications, Carlos Castro and Ratnasingham Sooryakumar and their colleagues from The Ohio State University report that the control system reduced the response time of prototype nano-robot components from several minutes to less than a second.

HIV Vaccine Elicits Neutralization of HIV Strains

An experimental vaccine regimen based on the structure of a vulnerable site on HIV elicited antibodies in mice, guinea pigs and monkeys that neutralize dozens of HIV strains from around the world. The findings were reported today in the journal Nature Medicine by researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and their colleagues.

New Insights into Hepatitis B Virus

Researchers at the University of Delaware, working with colleagues at Indiana University, have gained new insights into the virus that causes hepatitis B — a life-threatening and incurable infection that afflicts more than 250 million people worldwide.

Mathematical Model Developed to Understand Cancer Evolution

The concept of survival of the fittest most often applies to the competition that occurs within and between animal species, but evolutionary pressures can be found elsewhere–even in a cancerous tumor. Reporting in the journal PLOS ONE, Qian and Akçay suggest that incorporating evolutionary and ecological theory into cancer biology may help guide more effective treatment plans.

New Law Proposed For The Control Of Digital Health Data

India’s health ministry has proposed a law to govern data security in the healthcare sector that would give individuals complete ownership of their health data. Individuals would have the absolute right to refuse or allow data to be generated, collected, accessed, transmitted or used. And data collectors such as hospitals would be prohibited from refusing treatment to those who do not want their data collected or used.

Genetic Material from Alkhurma Hemorrhagic Fever Virus in Ticks Identified

In a new study, researchers at Uppsala University and other institutions have identified genetic material from the recently identified Alkhurma hemorrhagic fever virus in the tick species Hyalomma rufipes.

The discovery was made after thousands of ticks were collected from migratory birds captured in the Mediterranean basin. The results indicate that birds could contribute to spreading the virus to new geographical areas.

Student Athletes: Sleep Paralysis, Hallucinations are Widespread

Pilot data from a recent study suggest that sleep paralysis and dream-like hallucinations as you are falling asleep or waking up are widespread in student-athletes and are independently associated with symptoms of depression. This study is the first to examine the relationship between these sleep symptoms and mental health in student-athletes, independent of insufficient sleep duration or insomnia.

Opioid Epidemic and Challenges Prevailing Views Addressed

A new study sheds new light on the sharp rise in fatal drug overdoses in recent years, one of the most severe public health challenges of our time. The study found that the growth in fatal overdoses for non-Hispanic whites (NHWs) aged 22-56 years was sufficiently large to account for the entire growth in mortality rates (MR) and years of potential life lost (YPLL) for this population from 1999 to 2015.

Evaluation Of Benefits Of Residual Hair Cell Function For Speech In CI

A new study was to investigate the benefits of residual hair cell function for speech and music perception in bimodal pediatric Mandarin-speaking cochlear implant (CI) listeners. Speech and music performance was measured in 35 Mandarin-speaking pediatric CI users for unilateral (CI-only) and bimodal listening. Mandarin speech perception was measured for vowels, consonants, lexical tones, and sentences in quiet. Music perception was measured for melodic contour identification (MCI).
