Researchers are the first to characterize the ecology and fine-scale habitat use of 'near threatened' whitespotted eagle rays in Florida while also identifying areas of potential interactions between this species and multiple environmental threats. Biotelemetry provided unique insights into this species' occupancy, which is not apparent at the landscape-scale. Prolonged observations showed affinities for habitats of considerable recreational and commercial importance, like inlets, channels, and clam aquaculture lease sites close to shore.
These presentations feature ecological research that harnesses high-tech advances in new and exciting ways. All will be presented at the Ecological Society of America's upcoming virtual annual meeting, August 3-6, 2020.
In a breakthrough experiment, physicist and engineers at the CUNY ASRC have shown that it is possible to limit the movement of sound to a single direction without interruption even when there are deformations along the pathway. The findings pave the way for technologies with more robust sound wave integrity and advances in ultrasound imaging, sonar, and electronic systems that use surface acoustic wave technology.
Combining integrated photonics and MEMS technology, scientists from EPFL and Purdue University demonstrate monolithic piezoelectric control of integrated optical frequency combs with bulk acoustic waves. The technology opens up integrated ultrafast acousto-optic modulation for demanding applications.
The air around us is still getting more and more polluted. No wonder many scientists strive to find a way to purify it. Thanks to the work of an international team led by prof. Juan Carlos Colmenares from the Institute of Physical Chemistry, Polish Academy of Sciences, we are a big step closer to achieve this goal. They found a way to make an efficient reactive adsorbent able to purify the air from various toxic compounds, cheaply, and effectively.
Scientists have pioneered a new technique to produce arrays of sound produced entirely by heat.
Prof. TIAN Chao's group improved the imaging quality and 3D construction of the photoacoustic imaging, and applied them to in vivo sentinel lymph node imaging.
Levitation has long been a staple of magic tricks and movies. But in the lab, it's no trick. Scientists can levitate droplets of liquid, though mixing them and observing the reactions has been challenging. The pay-off, however, could be big as it would allow researchers to conduct contact-free experiments without containers or handling that might affect the outcome. Now, a team reporting in ACS' Analytical Chemistry has developed a method to do just that.
Breast cancer is the most common cancer in women. But individual tumors can vary significantly, presenting different spatial patterns within their mass. Researchers at the Technical University of Munich (TUM) and Helmholtz Zentrum München have now succeeded in visualizing spatial changes within tumors by means of optoacoustics. This method may be helpful for the future development of new drugs.
Scientists at Osaka University initiated a quantum random walk by shining lasers on a row of trapped ions. They showed that the observed locations of vibrations spreading out over time matched the predictions of quantum mechanics. This work may help elucidate unresolved questions in quantum chemistry and biology.
