New Findings: Microscope Measures Muscle Weakness

Biotechnologists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a system to accurately measure muscle weakness caused by structural changes in muscle tissue. The new method allows muscle function to be assessed using imaging without the need for sophisticated biomechanical recordings, and could in future even make taking tissue samples for diagnosing myopathy superfluous. The results have been published in the journal Light: Science & Applications.

Lung Function Monitoring of Patients with DMD at Home

Heart and thrombosis are responsible for much of the morbidity and mortality associated with Duchenne muscular dystrophy (DMD). Although regular monitoring of pulmonary function is recommended in order to detect deterioration, compliance with routine testing, such as hospital-based spirometry, is frequently poor. A new study in the Journal of Neuromuscular Diseases describes the at-home use of a child-compatible, hand-held device (HHD) that makes monitoring pulmonary function in teens more convenient and provides the data needed for better disease management.

Research: Bacterial Protein Find Materials for Smartphone

A newly discovered protein could help detect, target, and collect lanthanides, rare-earth metals used in smartphones, from the environment. A newly discovered protein could help detect, target, and collect from the environment the rare-earth metals used in smartphones.

Two new studies by researchers at Penn State describe the protein, which is 100 million times better at binding to lanthanides than to other metals like calcium. The study appears online in the journal Biochemistry, describes its unique structure, which likely plays a role in its remarkable selectivity for lanthanides.

Transforming India: Young People’s SRH Needs Take Centre Stage

It is not uncommon to hear the oft-quoted (and tired) phrase, “The youth are the leaders of tomorrow” being spouted at public gatherings blandly stated in policies and used in a multitude of reports/articles/documents. The numbers point in that direction: India is now home to more than 365 million young people in the age bracket of 10 – 24 years, with a growing youth population (15-24 years). But there is work that needs to go in for this demographic to truly actualize itself.

A Versatile Vaccine Against Emerging Tick-Borne Viruses

A group of researchers led by Michael Diamond of Washington University School of Medicine in St. Louis have developed a vaccine that is effective in mice against Powassan virus, an emerging tick-borne virus that can cause life-threatening encephalitis in humans. They also show that the vaccine produces antibodies that can protect the mice against other, related tick-transmitted flaviviruses. Their findings appear in the journal Cell Reports.

Air Pollution in Mexico Linked with Alzheimer's Pathology

A new study by researchers at the Universities of Montana, Valley of Mexico, Boise State, Universidad Veracruzana, National Institute of Pediatrics and Paul-Flechsig-Institute for Brain Research heightens together with German company Analytica Jena concerns about the evolving and relentless Alzheimer's pathology observed in young Metropolitan Mexico City (MMC) urbanites. These findings are published in the Journal of Alzheimer's Disease .

Gene Vital to Circadian Rhythms: New Study

Circadian rhythms (from the Latin circa diem – "around a day") based on the Earth's 24-hour rotation have been observed since the fourth century. But it's only recently that scientists have come to understand the fundamental role of circadian rhythms in everything from body temperature to reproduction to metabolism.

Disruptions of our internal clocks are implicated in many health issues, including sleep and affective disorders, cardiovascular disease, and certain types of cancer, to the tune of billions of dollars in health care costs.

Tiny Tic-Tac-Toe: Microscopic Board Made Using DNA, Research

Move over Mona Lisa, here you eat tic-tac-toe . It was just about a year ago that Caltech scientists in the laboratory of Lulu Qian, assistant professor of bioengineering, announced they had used a technique known as DNA origami to create tiles that could be designed to self-assemble into larger nanostructures that carry predesigned patterns . They chose to make the world's smallest version of the iconic Mona Lisa.
