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.

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.
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.
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.
The antibiotic-resistant Acinetobacter baumannii bacterium is one of the most globally harmful bacteria that cause nosocomial infections. Researchers at the University of Turku have discovered that the bacterium attaches to plastic medical devices using tiny finger-like structures. The researchers were able to develop antibodies that prevent the bacterial spread.
With rains starting to intermittently flood the Rohingya refugee camps, the World Health Organization and other health sector partners are further strengthening preventive and contingency measures to minimize the health impact of monsoons for the nearly 1.3 million vulnerable populations in Cox’s Bazar.
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.
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.
Foreign-born adults living in the United States had a lower prevalence of coronary heart disease and stroke than U.S.-born adults in nationally representative data spanning 2006-2014, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
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.
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.
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).
