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.

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.

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.

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.

Marine heatwaves devastate red gorgonians in the Medes Islands      (via sciencedaily.com)     Original source 

The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study shows that the extreme heatwave of 2022 caused an 'unprecedented' increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgr Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are 'alarming and threaten the viability' of this species of great value for the biodiversity of benthic ecosystems, since it is considered to be an inhabitant-forming species.

New way to spot beetle-killed spruce can help forest, wildfire managers      (via sciencedaily.com)     Original source 

A new machine-learning system can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation where identification is otherwise difficult. The automated process can help forestry and wildfire managers in their decisions. That's critical as the beetle infestation spreads.

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.
