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.

Researchers at the Center for Mind and Brain at the University of California, Davis have now been able to carry out functional MRI brain scans of sleeping toddlers and showed how specific brain regions are activated during memory recall in 2 year-olds.
Researchers have progressed from fearing for her son's life every night to being safe in the knowledge that his diabetes is well managed thanks to the long-term success of "miracle treatment" tablets. Frequently had life-threatening low blood sugar (hypos) at night as a result of the insulin injections he took several times a day to treat his neonatal diabetes. The study was published in The Lancet Diabetes and Endocrinology.
The U.S. Food and Drug Administration approved Fulphila (pegfilgrastim-jmdb) as the first biosimilar to Neulasta (pegfilgrastim) to decrease the chance of infection as suggested by febrile neutropenia (fever, often with other signs of infection, associated with an abnormally low number of infection-fighting white blood cells), in patients with non-myeloid (non-bone marrow) cancer who are receiving myelosuppressive chemotherapy that has a clinically significant incidence of febrile neutropenia.
According to a study, researchers examine mRNA drugs offer a promising new approach to deliver therapeutic replacement proteins, and novel strategies designed to engineer more stable and active proteins are further enhancing the potential of mRNA therapies. Specific examples of sequence engineering that led to improved expression, duration, and enzymatic activity of target proteins. The study was published in Nucleic Acid Therapeutics.
A teenager's father is murdered in Somalia, and the boy travels to the United States seeking asylum. Another teen's father and brother are murdered by extremist groups in Afghanistan and he too makes his way to the U.S. to seek asylum. Since both are minors, federal law decrees that they must be held separately from adults under the oversight of the Office of Refugee Resettlement (ORR).
Researchers have developed a new way of seeing when heavy wound scars are forming, and providing doctors the chance to intervene. Using new nanoparticles, the joint research team has shown in animals and human skin samples the potential to quickly and accurately predict whether a wound is likely to lead to excessive scarring as occurs in keloids and skin contractures. The study was published in the journal Nature Biomedical Engineering.
Anyone who gets an artificial hip or knee joint has to spend a lot of time in rehabilitation. The offers are scarce, though, and working people often cannot make the appointments due to time constraints. The result: the therapy is delayed, there are additional costs, and there is the added risk of possible health restrictions.
In the ReMove-It project, Fraunhofer and its partners have developed telemedicine-based exercise therapy that allows patients to organize their rehabilitation more flexibly. The efficacy has already been proved in a representative study, and ReMove-It is expected to be approved as a medical device by 2019.
NASA and private space companies like SpaceX plan to send humans to the red planet within the next 15 years but among the major challenges facing future crewed space missions is how to protect astronauts from the dangerous cosmic radiation of deep space. Researchers has identified the first potential treatment for the brain damage caused by exposure to cosmic rays, a drug that prevents memory impairment in mice exposed to simulated space radiation. The study was published in Scientific Reports.
