Published Breakthrough approach enables bidirectional BCI functionality
(via sciencedaily.com)
Original source 
Brain-computer interfaces or BCIs hold immense potential for individuals with a wide range of neurological conditions, but the road to implementation is long and nuanced for both the invasive and noninvasive versions of the technology. Scientists have now successfully integrated a novel focused ultrasound stimulation to realize bidirectional BCI that both encodes and decodes brain waves using machine learning in a study with 25 human subjects. This work opens up a new avenue to significantly enhance not only the signal quality, but also, overall nonivasive BCI performance by stimulating targeted neural circuits.
Published Some CRISPR screens may be missing cancer drug targets
(via sciencedaily.com)
Original source 
CRISPR/Cas9 gene editing has made possible a multitude of biomedical experiments including studies that systematically turn off genes in cancer cells to look for ones that the cancer cells heavily depend on to survive and grow. These genes, or 'cancer dependencies,' are often promising drug targets. But new research shows that many of these CRISPR screening experiments rely on components, called CRISPR/Cas9 guides, that do not perform equally well in cells from people of all ancestries, which can cause CRISPR screens to miss cancer dependencies.
Published When bacteria are buckling
(via sciencedaily.com)
Original source 
Filamentous cyanobacteria buckle at a certain length when they encounter an obstacle. The results provide an important basis for the use of cyanobacteria in modern biotechnology.
Published Nano-immunotherapy developed to improve lung cancer treatment
(via sciencedaily.com)
Original source 
Researchers have developed a new nanomedicine therapy that delivers anticancer drugs to lung cancer cells and enhances the immune system's ability to fight cancer. The team showed promising results for the new therapy in cancer cells in the lab and in mouse lung tumor models, with potential applications for improving care and outcomes for patients with tumors that have failed to respond to traditional immunotherapy.
Published Strengthener for graphene
(via sciencedaily.com)
Original source 
Layers of carbon atoms in a honeycomb array are a true supermaterial: their unusually high conductivity and favorable mechanical properties could further the development of bendable electronics, new batteries, and innovative composite materials for aeronautics and space flight. However, the development of elastic and tough films remains a challenge. A research team has now introduced a method to overcome this hurdle: they linked graphene nanolayers via 'extendable' bridging structures.
Published Self-assembling and disassembling swarm molecular robots via DNA molecular controller
(via sciencedaily.com)
Original source 
Researchers have succeeded in developing a DNA-based molecular controller. Crucially, this controller enables the autonomous assembly and disassembly of molecular robots, as opposed to manually directing it.
Published Novel insights into fluorescent 'dark states' illuminate ways forward for improved imaging
(via sciencedaily.com)
Original source 
Scientists address decades-long problem in the field of single-molecule fluorescence resonance energy transfer, paving the way for more accurate experiments.
Published Making ferromagnets ready for ultra-fast communication and computation technology
(via sciencedaily.com)
Original source 
Researchers have made a significant breakthrough in how to enable and exploit ultra-fast spin behavior in ferromagnets. The research paves the way for ultra-high frequency applications.
Published Lab achieves major gains in perovskite solar cell stability
(via sciencedaily.com)
Original source 
Researchers have developed new chemistry to achieve commercially relevant stability and performance for perovskite solar cells.
Published A conservation market could incentivize global ocean protection
(via sciencedaily.com)
Original source 
Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.
Published Scientists preserve DNA in an amber-like polymer
(via sciencedaily.com)
Original source 
With their 'T-REX' method, researchers developed a glassy, amber-like polymer that can be used for long-term storage of DNA, such as entire human genomes or digital files such as photos.
Published Technologies enable 3D imaging of whole human brain hemispheres at subcellular resolution
(via sciencedaily.com)
Original source 
A suite of three innovations enables high-resolution, high-throughput imaging of human brain tissue at a full range of scales and mapping connectivity of neurons at single cell resolution. To demonstrate the advance, researchers compared a brain region in an Alzheimer's and a control sample.
Published Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate
(via sciencedaily.com)
Original source 
The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.
Published Ancient ocean slowdown warns of future climate chaos
(via sciencedaily.com)
Original source 
When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.
Published Swimming microrobots deliver cancer-fighting drugs to metastatic lung tumors in mice
(via sciencedaily.com)
Original source 
Engineers have developed microscopic robots, known as microrobots, capable of swimming through the lungs to deliver cancer-fighting medication directly to metastatic tumors. This approach has shown promise in mice, where it inhibited the growth and spread of tumors that had metastasized to the lungs, thereby boosting survival rates compared to control treatments.
Published Mobile monitoring for an airborne carcinogen in Louisiana's 'Cancer Alley'
(via sciencedaily.com)
Original source 
Louisiana's southeastern corridor is sometimes known colloquially as 'Cancer Alley' for its high cancer incidence rates connected to industrial air pollution. Most of the region's air pollution-related health risks are attributed to ethylene oxide, a volatile compound used to make plastics and sterilize medical equipment. Researchers measured concerning levels of ethylene oxide in this area with mobile optical instruments, a technique they say could improve health risk assessments.
Published 'Synthetic' cell shown to follow chemical directions and change shape, a vital biological function
(via sciencedaily.com)
Original source 
In a feat aimed at understanding how cells move and creating new ways to shuttle drugs through the body, scientists say they have built a minimal synthetic cell that follows an external chemical cue and demonstrates a governing principle of biology called 'symmetry breaking.'
