    Newly discovered brain mechanism linked to anxiety, OCD — ScienceDaily

    The pandemic and its aftermath have raised anxiety to new levels. But the roots of anxiety-related conditions, including obsessive-compulsive spectrum disorder (OCSD), are still unclear. In a new study, University of Utah Health scientists discovered insights into the importance of a minor cell type in the brain — microglia — in controlling anxiety-related behaviors in […] More

    Whales not to be counted on as ‘climate savers’ — ScienceDaily

    Despite some hope that this would be the case, a new study led by Griffith University and a team of global researchers has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. Marine scientist Dr Olaf Meynecke and the team from the Griffith-led Whales […] More

    Proposed design could double the efficiency of lightweight solar cells for space-based applications — ScienceDaily

    When it comes to supplying energy for space exploration and settlements, commonly available solar cells made of silicon or gallium arsenide are still too heavy to be feasibly transported by rocket. To address this challenge, a wide variety of lightweight alternatives are being explored, including solar cells made of a thin layer of molybdenum selenide, […] More

    Destroying decommissioned hard drives is all about risk management

    Bottom line: Millions of hard drives are retired annually when their warranties expire, even if they are still in perfect operating condition. The overwhelming majority of these drives are not sent in for refurbishing or otherwise repurposed. Rather, they are destroyed. The Circular Drive Initiative (CDI), a consortium of technology companies promoting the reuse of […] More

    Sponge makes robotic device a soft touch — ScienceDaily

    A simple sponge has improved how robots grasp, scientists from the University of Bristol have found. This easy-to-make sponge-jamming device can help stiff robots handle delicate items carefully by mimicking the nuanced touch, or variable stiffness, of a human. Robots can skip, jump and do somersaults, but they’re too rigid to hold an egg easily. […] More

    Microsoft will pay $20 million for violating children’s online privacy on Xbox

    What just happened? Microsoft violated the Children’s Online Privacy Protection Act (COPPA), the US federal law conceived to protect the online privacy of children under the age of 13. Younger gamers were profiled without their parents’ consent, and data was retained for years, even for uncompleted accounts. Microsoft and the Federal Trade Commission (FTC) have […] More

    Measuring greenhouse gas from ponds improves climate predictions — ScienceDaily

    Shallow lakes and ponds emit significant amounts of greenhouse gases into the atmosphere, but emissions from these systems vary considerably and are not well understood. Now, a new Cornell University-led study measures methane and carbon dioxide emissions from 30 small lakes and ponds (one acre or less) in temperate areas of Europe and North America, […] More

    Healthcare chain is using a GPT-4-based AI to generate medical records

    What just happened? Carbon Health is a US healthcare chain describing itself as a human-centered “hybrid healthcare provider” which uses the power of technology to make “great care” more accessible to everyone. The company is of course sold on the new generative AI trend too, and it already has an automation tool writing notes in […] More

    Very long baseline array finds classical novae are anything but simple — ScienceDaily

    While studying classical novae using the National Radio Astronomy Observatory’s Very Long Baseline Array (VLBA), a graduate researcher uncovered evidence the objects may have been erroneously typecast as simple. The new observations, which detected non-thermal emission from a classical nova with a dwarf companion, were presented today at a press conference during the 242nd proceedings […] More

    How much did the Neo Geo game console cost when it launched in 1990?

    Choose your answer and the correct choice will be revealed. The Neo-Geo was a notoriously expensive cartridge-based system that served as the company’s entry into the crowded 16-bit console market, the system was unique at the time for its ability to play arcade-quality games at home. The system was initially only available for rent by […] More

    Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants — ScienceDaily

    Symbiotic and pathogenic fungi that interact with plants are distantly related and don’t share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants. Sebastian Schornack’s research […] More

    Guide to Choosing a New Graphics Card

    Graphics cards are among the most complex, expensive, and sizeable components you can get for a PC. So when it comes to upgrading to a new model, it’s crucial to ensure that you’re choosing the right one for both your PC and your wallet. While there is no shortage of outstanding options among the hundreds […] More

    New class of antibiotics to fight resistant bacteria — ScienceDaily

    Health professionals are in urgent need of new antibiotics to tackle resistant bacteria. Researchers at the University of Zurich and the company Spexis have now modified the chemical structure of naturally occurring peptides to develop antimicrobial molecules that bind to novel targets in the bacteria’s metabolism. Each year, more than five million people worldwide die […] More

    Producing large, clean 2D materials made easy — ScienceDaily

    Ever since the discovery of the two-dimensional form of graphite (called graphene) almost twenty years ago, interest in 2D materials with their special physical properties has skyrocketed. Famously, graphene was produced by exfoliating bulk graphite using sticky tape. Although it was good enough for a Nobel Prize, this method has its drawbacks. An international team […] More

    Fragments of spherical ‘Buckyball’ molecules have stable electron-accepting ability with great practical potential — ScienceDaily

    Researchers at Kyoto University in Japan have gained new insights into the unique chemical properties of spherical molecules composed entirely of carbon atoms, called fullerenes. They did it by making flat fragments of the molecules, which surprisingly retained and even enhanced some key chemical properties. The team published their findings in the journal Nature Communications. […] More

    Explaining the interaction between quantized vortices and normal fluids — ScienceDaily

    Liquid helium-4, which is in a superfluid state at cryogenic temperatures close to absolute zero (-273°C), has a special vortex called a quantized vortex that originates from quantum mechanical effects. When the temperature is relatively high, the normal fluid exists simultaneously in the superfluid helium, and when the quantized vortex is in motion, mutual friction […] More

    Biodegradable plastic from sugar cane also threatens the environment — ScienceDaily

    Plastic made from cane sugar also threatens the environment. Researchers from the University of Gothenburg have found that perch change their behaviour when exposed to so-called bioplastic. Traditional plastic, based on fossil oil, has flooded the earth and there is microplastic in all living things. This has led to intensive research for alternatives that decompose […] More
