Published Future risk of coral bleaching set to intensify globally
(via sciencedaily.com) Original source Researchers have projected future marine heatwaves will cause coral reefs to be at severe risk of bleaching for longer periods than previously seen.
Published Ocean's loss of oxygen caused massive Jurassic extinction: Could it happen again?
(via sciencedaily.com) Original source Researchers have found a chemical clue in Italian limestone that explains a mass extinction of marine life in the Early Jurassic period, 183 million years ago. Volcanic activity pumped out CO2, warming oceans and lowering their oxygen levels. The findings may foretell the impact climate change and oxygen depletion might have on today's oceans.
Published Frog 'saunas' a lifeline for endangered frog populations
(via sciencedaily.com) Original source New biologist-designed shelters will help endangered frogs survive the devastating impacts of a deadly fungal disease by regulating their body temperature to fight off infections.
Published Next platform for brain-inspired computing
(via sciencedaily.com) Original source Computers have come so far in terms of their power and potential, rivaling and even eclipsing human brains in their ability to store and crunch data, make predictions and communicate. But there is one domain where human brains continue to dominate: energy efficiency.
Published Robots face the future
(via sciencedaily.com) Original source Researchers have found a way to bind engineered skin tissue to the complex forms of humanoid robots. This brings with it potential benefits to robotic platforms such as increased mobility, self-healing abilities, embedded sensing capabilities and an increasingly lifelike appearance. Taking inspiration from human skin ligaments, the team included special perforations in a robot face, which helped a layer of skin take hold.
Published Meet CARMEN, a robot that helps people with mild cognitive impairment
(via sciencedaily.com) Original source Meet CARMEN, short for Cognitively Assistive Robot for Motivation and Neurorehabilitation -- a small, tabletop robot designed to help people with mild cognitive impairment (MCI) learn skills to improve memory, attention, and executive functioning at home.
Published Boosting biodiversity without hurting local economies
(via sciencedaily.com) Original source Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.
Published Prying open the AI black box
(via sciencedaily.com) Original source Meet SQUID, a new computational tool. Compared with other genomic AI models, SQUID is more consistent, reduces background noise, and can yield better predictions regarding critical mutations. The new system aims to bring scientists closer to their findings' true medical implications.
Published Can AI learn like us?
(via sciencedaily.com) Original source Scientists have developed a new, more energy-efficient way for AI algorithms to process data. His model may become the basis for a new generation of AI that learns like we do. Notably, these findings may also lend support to neuroscience theories surrounding memory's role in learning.
Published When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change
(via sciencedaily.com) Original source Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.
Published Researchers leverage shadows to model 3D scenes, including objects blocked from view
(via sciencedaily.com) Original source A new technique can model an entire 3D scene, including areas hidden from view, from just one camera image. The method relies on image shadows, which provide information about the geometry and location of hidden objects.
Published Breakthrough may clear major hurdle for quantum computers
(via sciencedaily.com) Original source The potential of quantum computers is currently thwarted by a trade-off problem. Quantum systems that can carry out complex operations are less tolerant to errors and noise, while systems that are more protected against noise are harder and slower to compute with. Now a research team has created a unique system that combats the dilemma, thus paving the way for longer computation time and more robust quantum computers.
Published Researchers teach AI to spot what you're sketching
(via sciencedaily.com) Original source A new way to teach artificial intelligence (AI) to understand human line drawings -- even from non-artists -- has been developed.
Published Climate change: rising temperatures may impact groundwater quality
(via sciencedaily.com) Original source As the world's largest unfrozen freshwater resource, groundwater is crucial for life on Earth. Researchers have investigated how global warming is affecting groundwater temperatures and what that means for humanity and the environment. Their study indicates that by 2100, more than 75 million people are likely to be living in regions where the groundwater temperature exceeds the highest threshold set for drinking water by any country.
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 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.
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 To heal skin, scientists invent living bioelectronics
(via sciencedaily.com) Original source Engineers have created a patch that combines sensors and bacteria to interact with the body.
Published Towards a new era in flexible piezoelectric sensors for both humans and robots
(via sciencedaily.com) Original source Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, researchers tackled these issues by developing a novel piezoelectric composite material made from electrospun polyvinylidene fluoride nanofibers combined with dopamine. Sensors made from this material showed significant performance and stability improvements at a low cost, promising advancements in medicine, healthcare, and robotics.
