To be able to reproduce and become effective disease carriers, mosquitoes must first attain optimal body size and nutritional status. A pair of researchers at the University of California, Riverside, have succeeded in using CRISPR-Cas9, a powerful tool for altering DNA sequences and modifying gene function, to decrease mosquito body size, moving the research one step closer to eliminating mosquitoes that carry dengue fever and Zika virus.
A new collaborative study has investigated Arctic shrub-snow interactions to obtain a better understanding of the far north's tundra and vast permafrost system. Incorporating extensive in situ observations, Los Alamos National Laboratory scientists tested their theories with a novel 3D computer model and confirmed that shrubs can lead to significant degradation of the permafrost layer that has remained frozen for tens of thousands of years. These interactions are driving increases in discharges of fresh water into rivers, lakes and oceans.
'Exercise is a low-cost, non-invasive modality,' noted Dr. John DeLuca, 'so we are very interested in learning more about how activity results in these improvements. Rethinking how we view exercise in the long-term management of MS and other neurological conditions is our first step. We anticipate that the PRIMERS framework will accelerate advances in treatment by integrating the contributions from neuroscience, neurophysiology, and neurorehabilitation."
The architecture of each person's brain is unique, and differences may influence how quickly people can complete various cognitive tasks. But how neuroanatomy impacts performance is largely an open question. To learn more, scientists are developing a new tool -- computational models of the brain -- to simulate how the structure of the brain may impact brain activity and, ultimately, human behavior.
Scientists at Scripps Research have successfully tested a potential new smoking-cessation treatment in rodents.
NASA's Aqua satellite captured an infrared image of the remnants of former Tropical Storm Tara after it dissipated near the coast of western Mexico's Jalisco state. Jalisco is a western Mexican state along the Eastern Pacific Ocean.
A new study presents a novel method of using a microfluidic flow cell array to achieve precise and reproducible control of cell deposition onto engineered tissue constructs to produce tunable cell patterns and generate essential integration zones.
Researchers have developed a new device that can be used to visualize how sound-induced vibrations travel through the ear.
There just aren't enough kidney transplants available for the millions of people with renal failure. Aside from a transplant, the only alternative for patients is to undergo regular dialysis sessions to clear harmful cellular waste from their bodies. Now, scientists report in ACS Nano a new urea sorbent that could accelerate progress toward the development of a lightweight, wearable artificial kidney with the potential to make dialysis more convenient, comfortable and effective.
Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed a new method to 3D print lithium-ion batteries in virtually any shape. They report their results in ACS Applied Energy Materials.
