(via sciencedaily.com) Original source An analysis of how synaptic proteins change during early development reveals differences between mice and marmosets but also what's different in individuals with autism spectrum disorders. The findings offer first insights into the mechanism behind synaptic development and open up routes for research on possible treatments.
Published New method developed to isolate HIV particles
(via sciencedaily.com) Original source Researchers have developed a new method to isolate HIV from samples more easily, potentially making it easier to detect infection with the virus. They focus on peptide nanofibrils (PNFs) on magnetic microparticles, a promising tool and hybrid material for targeted binding and separation of viral particles.
Published Nuclear fusion, lithium and the tokamak: Adding just enough fuel to the fire
(via sciencedaily.com) Original source Building upon recent findings showing the promise of coating the inner surface of the vessel containing a fusion plasma in liquid lithium, researchers have determined the maximum density of uncharged particles at the edge of a plasma before certain instabilities become unpredictable. The research includes observations, numerical simulations and analysis from their experiments inside a fusion plasma vessel called the Lithium Tokamak Experiment-Beta (LTX- ). This is the first time such a level has been established for LTX- , and knowing it is a big step in their mission to prove lithium is the ideal choice for an inner-wall coating in a tokamak because it guides them toward the best practices for fueling their plasmas.
Published Going 'back to the future' to forecast the fate of a dead Florida coral reef
(via sciencedaily.com) Original source How coral populations expand into new areas and sustain themselves over time is limited by the scope of modern observations. Going back thousands of years, a study provides geological insights into coral range expansions by reconstructing the composition of a Late Holocene-aged subfossil coral death assemblage in an unusual location in Southeast Florida and comparing it to modern reefs throughout the region. Findings offer a unique glimpse into what was once a vibrant coral reef assemblage and discover if history can repeat itself in the face of climate change.
Published How extratropical ocean-atmosphere interactions can contribute to the variability of jet streams in the Northern Hemisphere
(via sciencedaily.com) Original source Ocean-atmosphere coupling, the exchange in energy between the ocean and atmosphere, influences teleconnection patterns, the climate effects across vast geographical areas. However, its impact outside the tropics is unclear. A group of researchers examined the effect of ocean coupling on atmospheric circulation patterns in the Northern Hemisphere. They found that extratropical ocean-atmosphere coupling enhances teleconnection patterns and causes more meandering westerly jet streams, which are linked to extreme weather events.
Published Revolutionary biomimetic olfactory chips to enable advanced gas sensing and odor detection
(via sciencedaily.com) Original source A research team has addressed the long-standing challenge of creating artificial olfactory sensors with arrays of diverse high-performance gas sensors. Their newly developed biomimetic olfactory chips (BOC) are able to integrate nanotube sensor arrays on nanoporous substrates with up to 10,000 individually addressable gas sensors per chip, a configuration that is similar to how olfaction works for humans and other animals.
Published Long-period oscillations control the Sun's differential rotation
(via sciencedaily.com) Original source The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations discovered in 2021 play a crucial role in controlling the Sun's rotational pattern. The long-period oscillations are analogous to the baroclinically unstable waves in Earth's atmosphere that shape the weather. In the Sun, these oscillations carry heat from the slightly hotter poles to the slightly cooler equator.
Published Artificial reef designed by MIT engineers could protect marine life, reduce storm damage
(via sciencedaily.com) Original source Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.
Published Understanding cattle grazing personalities may foster sustainable rangelands
(via sciencedaily.com) Original source New research finds that not all cattle are the same when it comes to grazing, and knowing that could lead to better animal health and range conditions.
Published A combination of approved drugs enhances the delivery of anti-bacterial medications to treat tuberculosis
(via sciencedaily.com) Original source Researchers have found that approved drugs that were originally shown to normalize blood vessels surrounding tumors (to improve drug delivery to cancer cells) can enhance the delivery of anti-microbial medications to kill tuberculosis bacteria residing in the lungs.
Published Astronomers conduct first search for forming planets with new space telescope
(via sciencedaily.com) Original source Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.
Published Climate change policies lose popularity when combined with pausing regulations or social justice
(via sciencedaily.com) Original source Legislators love bundling things together. It lets them accomplish more with less hassle and attempt to make legislation more appealing to a broader group. But a new study suggests that this can sometimes backfire. The authors found that pairing climate policies with other policies does not necessarily increase their popular appeal, and can actually reduce public support.
Published North American cities may see a major species turnover by the end of the century
(via sciencedaily.com) Original source Climate change may dramatically affect the animal species observed in North American cities, according to a new study.
Published Persistent hiccups in a far-off galaxy draw astronomers to new black hole behavior
(via sciencedaily.com) Original source Astronomers have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state.
Published Food matters: Healthy diets increase the economic and physical feasibility of 1.5°C
(via sciencedaily.com) Original source A global shift to a healthier, more sustainable diet could be a huge lever to limit global warming to 1.5 C, researchers find. The resulting reduction of greenhouse gas emissions would increase the available carbon budget compatible with limiting global warming to 1.5 C, and allow to achieve the same climate outcome with less carbon dioxide removal and less stringent CO2 emissions reductions in the energy system. This would also reduce emission prices, energy prices and food expenditures.
Published Land under water: What causes extreme flooding?
(via sciencedaily.com) Original source If rivers overflow their banks, the consequences can be devastating -- just like the catastrophic floods in North Rhine-Westphalia and Rhineland-Palatinate of 2021 showed. In order to limit flood damage and optimize flood risk assessment, we need to better understand what factors can lead to extreme forms of flooding and to what extent. Using methods of explainable machine learning, researchers have shown that floods are more extreme when several factors are involved in their development.
