Combining two different polymer forms can switch manufacturing of silicone parts from molding, casting and spin coating of simple forms to 3-D printing of complex geometries with better mechanical characteristics and better biological adhesion, according to a team of Penn State researchers.
Researchers have, for the first time, used a material's persistent photoconductivity to stimulate neurotype cells. The technique, which is relatively simple, should facilitate future research on using charge to influence cellular behavior.
A new synthetic hormone promises to tease apart the many different roles of the plant hormone auxin and could lead to a new way to ripen fruit.
A new article in the February 2018 issue of SLAS Technology describes a new platform that could change the way cancer is diagnosed and treated by automating the isolation of circulating tumor cells (CTCs) directly from cancer patient blood. This article provides unique insight into the development of a commercial system that has the potential to change the standard of care in cancer diagnosis and treatment.
Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids or liquids even small insects. For the first time University of Bristol engineers have shown it is possible to stably trap objects larger than the wavelength of sound in an acoustic tractor beam. This discovery could enable the manipulation of drug capsules or micro-surgical implements within the body. The discovery could even lead to levitating humans.
MIT researchers have developed hardware that uses electric fields to move droplets of chemical or biological solutions around a surface, mixing them in ways that could be used to test thousands of reactions in parallel.
Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories. The new research results will appear as the cover story on 19th January in the renowned scientific journal Science.
Scientists from VIB-UGent have discovered insights for a possible new therapy for eczema that also reduces the severity of asthma. The findings are an important next step in understanding the relationship between the two inflammatory diseases and to developing effective therapies. The results of the study are published in the Journal of Investigative Dermatology.
Geneticists have solved a century-old mystery by discovering a remarkable mechanism that enables plants to count their chromosomes. Their ability to detect imbalances in male and female contributions to the next generation determines their progeny's viability and fertility.
Viruses are the most abundant and one of the least understood biological entities on Earth. They might also exist in space, but as of yet scientists have done almost no research into this possibility. Portland State University biology professor Ken Stedman and colleagues are trying to change this through their article "Astrovirology: Viruses at Large in the Universe," published in the February 2018 issue of the journal Astrobiology.
