Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of Physics developed a thickness-controlled black phosphorous tunnel field-effect transistor (TFET) that shows 10-times lower switching power consumption as well as 10,000-times lower standby power consumption than conventional complementary metal-oxide-semiconductor (CMOS) transistors.
In a study published in Scientific Reports, a team of international researchers led by University of Hawai'i (UH) at Mānoa postdoctoral fellow Jamie Caldwell used a statistical technique typically employed in human epidemiology to determine the ecological risk factors affecting the prevalence of two coral diseases--growth anomalies, abnormalities like coral tumors, and white syndromes, infectious diseases similar to flesh eating bacteria.
Brazilian researchers working in collaboration with Canadian scientists demonstrated that all medulloblastoma tumor subtypes express two stem cell markers: BMI1 and CD133. When they induced DNA chromatin relaxation, tumor cell viability was reduced with down-regulation of BMI1 and CD133. These anti-tumor effects could be potentiated by concurrent inhibition of MAPK/ERK signaling.
A new eye scan could help identify autism in children years earlier than currently possible. The non-invasive eye scan utilises a hand-held device to find a pattern of subtle electrical signals in the retina that are different in children on the autism spectrum, which are directly linked to differences in their brain development.
A Simon Fraser University-led research team has found significant evidence that human activity in estuaries is impacting juvenile Pacific and Atlantic salmon. The team's review of 167 peer-reviewed studies identified negative impacts from several stressors, including the effects of flood-protecting tidal gates, pollution and habitat modification.
Three scientists from the University of Chicago have run the numbers, and they believe there may be a way to make a material that could conduct both electricity and energy with 100% efficiency--never losing any to heat or friction.
The governing body for the Paralympics recently lowered the allowable height for sprinters who use prosthetic legs, or blades, during competition. The rules are based on the assumption that the taller you are the faster you run. But a new study has found otherwise.
Many Caribbean coral reefs are heavily degraded, yet their pre-human, natural states are often assumed or estimated using space-for-time substitution approaches.
Cornell University researchers have found a new species of soil bacteria that is particularly adept at breaking down organic matter, including the cancer-causing chemicals that are released when coal, gas, oil and refuse are burned.
The Biophotonics Imaging Lab at the Beckman Institute, led by Dr. Stephen Boppart, has recently published papers in the Proceedings of the National Academy of Sciences and in Precision Oncology that use label-free microscopic techniques to visualize extracellular vesicles, which are associated with cancer.
