Researchers use statistical methods on video data to quantitatively determine the biomechanical techniques correlated with successful judo throws. This work may assist in developing supervised or self-guided training routines. Many athletic training regimens use repetition to perfect technique. However, seeing the difference between correct and improper form can often require the keen eye of an…

Scientists have developed a tool called FloChip, a new microfluidic take on the widely used chromatin immunoprecipitation (ChIP) technique. By automating and cutting the cost of ChIP and sequential-ChIP, FloChIP has the potential to become a widely used tool for the study of chromatin biology and gene regulation. When the protein reaches its target location,…

Researchers have designed a new chip-integrated light source that can transform infrared wavelengths into visible wavelengths, which have been difficult to produce with technology based on silicon chips. This flexible approach to on-chip light generation is poised to enable highly miniaturized photonic instrumentation that is easy to manufacture and rugged enough to use outside the…

Researchers have moved closer toward this goal by developing a nanopore sequencing platform that, for the first time, can detect the presence of nucleobases, the building blocks of DNA and RNA. Researchers at The University of Texas at Dallas have moved closer toward this goal by developing a nanopore sequencing platform that, for the first…

Scientists have developed a flexible and wearable vibration responsive sensor. When this sensor is attached to a neck, it can precisely recognize voice through vibration of the neck skin and is not affected by ambient noise or the volume of sound. Professor Kilwon Cho of Chemical Engineering and Professor Yoonyoung Chung of Electronic and Electric…

Researchers report that they have developed a gel that, when exposed to near infrared (NIR) light, safely whitens teeth without the burn. The growing demand for selfie-ready smiles has made tooth whitening one of the most popular dental procedures. Treatments at a dentist’s office are effective, but they use high-concentration hydrogen peroxide (30-40%). Home bleaching…

Mosquito-transmitted diseases such as malaria, dengue and yellow fever are responsible for hundreds of thousands of deaths every year. A new low-cost imaging system could make it easier to track mosquito species that carry disease, enabling a more timely and targeted response. «A remote system like ours can dramatically reduce the labor needed to monitor…

A highly portable and rapid prostate cancer screening kit could provide early warning to populations with higher incidence of prostate cancer and particularly those with limited access to health care, such as African American men. The proof-of-concept test, described online Nov. 12 in the journal Current Research in Biotechnology, is inexpensive and uses a test…

Wearable and implantable devices may allow for intensive self-care for patients with kidney failure outside of the clinic. In their feature article, Shuvo Roy, PhD (University of California, San Francisco) and his colleagues note that traditional hemodialysis performed in clinics has a number of shortcomings, with patients reporting burdens related to fatigue, poor sleep, inability…

Researchers have developed a new design of vertical-cavity surface-emitting laser (VCSEL) that demonstrates record-fast temporal bandwidth. VCSELs are a vital class of semiconductor laser diodes accompanying a monolithic laser resonator that emits light in a direction perpendicular to the chip surface. This class of lasers is gaining market importance given their compact size and high…
