In this edition:We introduce FLAVARS, a multimodal foundation language and vision alignment model for remote sensing; Managed-retention memory, a new class of memory which is more optimized to store key data structures for AI inference workloads; and Enhanced detection of macular telangiectasia type 2 (MacTel 2) using self-supervised learning and ensemble models.We present a new approach to generalizing symbolic automata, which brings together a variety of classic automata and logics in a unified framework with all the necessary ingredients to support symbolic model checking moduloA.And we invite you to join an upcoming workshop: LLM4Eval@WSDM 2025: Large Language Models for Evaluation in Information Retrieval. LLM4Eval is a promising technique in the areas of automated judgments, natural language generation, and retrieval augmented generation (RAG) systems. Researchers from Microsoft and experts from industry and academia will explore this technique at an interactive workshop on Friday, March 14, in Hanover, Germany.NEW RESEARCHIn the field of remote sensing, imagery is generally dense with objects and visual content which can vary regionally across the globe. This creates a need for vision-language datasets to be highly detailed when describing imagery, and for pretraining to better balance visual task performance while retaining the ability to perform zero-shot classification and image-text retrieval.One strategy is to combine paired satellite images and text captions for pretraining performant encoders for downstream tasks. However, while contrastive image-text methods like CLIP enable vision-language alignment and zero-shot classification ability, CLIPs vision-only downstream performance tends to degrade compared to image-only pretraining, such as Masked Autoencoders (MAE).To better approach multimodal pretraining for remote sensing, researchers from Microsoft propose a pretraining method that combines the best of both contrastive learning and masked modeling, along with geospatial alignment via contrastive location encoding, in the recent paper: FLAVARS: A Multimodal Foundational Language and Vision Alignment Model for Remote Sensing. The research shows that FLAVARS significantly outperforms a baseline of SkyCLIP for vision-only tasks such as KNN classification and semantic segmentation, +6% mIOU on SpaceNet1, while retaining the ability to perform zero-shot classification, unlike MAE pretrained methods.Read the paperNEW RESEARCHAI clusters today are one of the major uses of high bandwidth memory (HBM), a high-performance type of computer memory. However, HBM is suboptimal for AI inference workloads for several reasons. Analysis shows that HBM is overprovisioned on write performance, underprovisioned on density and read bandwidth, and has significant energy-per-bit overhead. It is also expensive, with lower yield than DRAM due to manufacturing complexity.In a recent paper: Managed-Retention Memory: A New Class of Memory for the AI Era, researchers from Microsoft propose a memory class which is more optimized to store key data structures for AI inference workloads. The paper makes the case that MRM may finally provide a path to viability for technologies that were originally proposed to support storage class memory (SCM). These technologies traditionally offered long-term persistence (10+ years) but provided poor IO performance and/or endurance. MRM makes different trade-offs, and by understanding the workload IO patterns, MRM foregoes long-term data retention and write performance for better potential performance on the metrics important for AI inference.Read the paperNEW RESEARCHMacular telangiectasia type 2 (MacTel) is a retinal disease that is challenging to diagnose. While increased awareness has led to improved diagnostic outcomes, MacTel diagnosis relies significantly upon a multimodal image set and the expertise of clinicians familiar with the disease. Optical coherence tomography (OCT) imaging has emerged as a valuable tool for the diagnosis and monitoring of various retinal diseases.With the increasing integration of OCT into clinical practice, deep learning models may be able to achieve accurate MacTel prediction comparable to that of retinal specialists, even when working with limited data.Researchers from Microsoft and external colleagues address this challenge in a recent paper: Enhanced Macular Telangiectasia Type 2 Detection: Leveraging Self-Supervised Learning and Ensemble Models. Published in the journal of Ophthalmology Science, the paper focuses on the accurate classification of macular telangiectasia type 2 using OCT images, with the overarching goal of facilitating early and precise detection of this neurodegenerative disease.The researchers present results leveraging self-supervised learning and ensemble models, showing their approach improves both MacTel classification accuracy and interpretability when compared to the use of individual models. Ensemble models exhibited superior agreement with the assessments of the most experienced individual human experts, as well as the ensemble of human experts.Read the paperMicrosoft research podcastCollaborators: Silica in space with Richard Black and Dexter GreeneCollege freshman Dexter Greene and Microsoft research manager Richard Black discuss how technology that stores data in glass is supporting students as they expand earlier efforts to communicate what it means to be human to extraterrestrials.Listen nowOpens in a new tab NEW RESEARCHSymbolic automata are finite state automata that support potentially infinite alphabets, such as the set of rational numbers, generally applied to regular expressions and languages over finite words. In symbolic automata (or automata moduloA), an alphabet is represented by an effective Boolean algebraA, supported by a decision procedure for satisfiability. Regular languages over infinite words (so called -regular languages) have a rich history paralleling that of regular languages over finite words, with well-known applications to model checking via Bchi automata and temporal logics.In a recent paper: Symbolic Automata: Omega-Regularity Modulo Theories, researchers from Microsoft generalize symbolic automata to support -regular languages viatransition termsandsymbolic derivatives. This brings together a variety of classic automata and logics in a unified framework that provides all the necessary ingredients to support symbolic model checking moduloA.Read the paperEVENTLLMs have shown increasing task-solving abilities not present in smaller models. Using LLMs for automated evaluation (LLM4Eval) is a promising technique in the areas of automated judgments, natural language generation, and retrieval augmented generation (RAG) systems.Join researchers from Microsoft and experts from industry and academia for a discussion on using LLMs for evaluation in information retrieval at LLM4Eval Workshop WSDM 2025 (opens in new tab), March 14, 2025, in Hanover, Germany.This interactive workshop will cover automated judgments, RAG pipeline evaluation, altering human evaluation, robustness, and trustworthiness of LLMs for evaluation in addition to their impact on real-world applications.

Below, youll find a diverse selection of floorstanding speakers, each chosen for its ability to deliver exceptional audio in its own unique way.Best overall design: Polk Legend L800Polk Why it made the cut: The Legend L800 redefines stereo with its patented SDA technology, delivering a spacious, three-dimensional soundstage that will convince you that youre seeing an album live from the front row.SpecsDrivers: Two sets per speaker: two 1 tweeters, two 5.25 midrange, two 10 woofersFrequency response: 32 Hz 38 kHz (-3dB)Dimensions: 48.6 H x 17.99 W x 17.38 DBuilt-in subwoofers: NoPrice: $2,999 eachProsSDA technology creates an astonishingly lifelike stereo imageFlagship driver technologies deliver natural, balanced soundBraced cabinet minimizes resonancesConsBulky footprintPolks flagship Legend L800 floorstanding speaker re-introduces an inventive approach to stereo sound developed by Matthew Polk in the 1980s. At the heart of its design is Stereo Dimensional Array (SDA) technology, which uses a second driver array alongside the traditional drivers to eliminate interaural crosstalkthe distortion that blurs stereo imaging in traditional speakers.In a nutshell, SDA drivers produce a signal thats out of phase with the interaural crosstalk signal coming from the opposite channel. When these signals arrive at your ear at the same time, they cancel each other out, leaving the true stereo signal. This produces an expansive soundstage that extends far beyond the physical placement of the speakers, immersing you in a breathtakingly lifelike audio experience. Whether youre listening to an intimate jazz trio or the sweeping score of a blockbuster film, every sonic image is reproduced with uncanny accuracy.The L800 pairs Polks Pinnacle Ring Radiator tweeter for crisp, high-frequency clarity with Turbine Cone midrange drivers for lifelike vocals and instruments. Dual 10-inch woofers deliver deep, tight bass thats both powerful and controlled, and a unique port design uses diffusors and flares to smooth airflow for distortion-free low-end, even at high volumes. (The L800 can be fitted with Polks L900 Height Module for Dolby Atmos overhead effects.)The L800 makes a statement with its formidable shape and premium woodgrain finish, available in Piano Black or Brown Walnut. Built with internal bracing for resonance-free sound, the L800 is as much a visual centerpiece as it is an acoustic powerhouse.If youre looking to bring the ultimate stereo or home theater experience into your living room, Polk Legend L800 produces stereo sound as it was meant to be heardexpansive, immersive, and astonishingly real.Polks SDA technology is virtualized in some of the companys soundbars, letting you experience a similar soundstage for a fraction of the cost of the L800. Check out the MagniFi Mini AX, which produces surprisingly wide sound in a unit measuring just a foot wideand comes with a wireless sub.Want to stick with two-channel but on a much tighter budget? The Polk Reserve Series features some of the Legends trickle-down tech, like the Pinnacle Ring Radiator tweeter and Turbine Cone midrange woofers, but priced starting around $549 each for the entry-level R500. Bassheads, though, might end up wanting more low-end. So, if you need more dynamic range but are not ready to add a subwoofer, step up to the 6.5-inch woofers of theR600 or the 8-inch woofers of theR700.Best powered: KEF LS60 WirelessTony Ware Why it made the cut: The KEF LS60 Wireless redefines what a powered wireless speaker can achieve, offering true hi-fi performance with its cutting-edge Uni-Q driver technology, tri-amped precision, and seamless streaming capabilitiesall in a sleek, minimalist design tailored for modern music enthusiasts.SpecsDrivers: 5 per speaker (two 1 tweeters, two 5.25 midrange, two 10 woofers)Frequency response: 31 Hz 24 kHzDimensions: 48.6 H x 17.99 W x 17.38 DBuilt-in subwoofers: NoPrice: $4,999/pr.ProsExceptional sound clarity with wide, immersive soundstageComprehensive streaming and connectivity optionsBuilt-in tri-amped system with 1,400W of total power, just add outletsConsHighest-resolution playback requires a wired connectionThe KEF LS60 Wireless reimagines hi-fi performance in a sleek, connected speaker thats as stylish as it is capable.

Recognizing an emerging market of budding audio enthusiasts the two-channel and home cinema curious JBL launched its own soundbar alternative. Available in Espresso (wood) and Latte (white) enclosures, the flagship L280F floorstanders are rockin rectangles that can blend into the background of a Gen Z apartment. But theyll take center stage once fed some signal.The feature that immediately stands out is the 1-inch anodized aluminum dome tweeter of this 2.5-way tower is mounted in a next-generation HDI [High-Definition Imaging] Horn (trickle-down waveguide tech from the high-end custom installation Synthesis line). This ensures a wide stereo stage and sibilance-free intelligibility. Thats paired with two dual 8-inch polycellulose ribbed woofers and dual flared rear ports (so dont back them up too close to the wall, but do remember to toe them in 40-60 degrees). Paper cones have a more natural tone, allowing for midrange/bass without breakup. Its a high-output system thats a balance between bright, airy, engaging, and low-end anchored. And with some EQ tweakswhich can be done manually or with the optimization built into JBLs matching Modern Audio AV receiver lineyou can achieve maximum linearity and clarity.Whats particularly nice about JBLs approach is you can start with an affordable hi-fi system, getting two of the L280F speakers for the price of one of our value pick above. Later, you can scale up to a 5.1 multi-channel system if/when the urge takes holdall without fear of tonal mismatch. The full Stage 2 line includes multiple towers with dedicated posts for adding height modules, as well as bookshelf/standmount, center channel, and subwoofer options.What to consider when choosing the best floorstanding speakersChoosing floorstanding speakers can feel overwhelming with so many factors to weigh, from sound quality and aesthetics to technical specifications. (New to the world of speaker technology? Well help you get up to speed on the basics.) Here, we focus on a few key essentials: room size, bass response, build quality, and of course, budget. By prioritizing these considerations, you can narrow down the options and find speakers that fit seamlessly into your space and provide outstanding audio tailored to your needs.The size of your spaceThe size of your room is a critical factor in choosing floorstanding speakers. Larger rooms generally benefit from speakers with more powerful drivers and greater wattage, which can fill the space with dynamic sound. Smaller rooms, however, may experience distortion or muddiness if the speakers are too powerful for the space. Compact towers or models designed for near-field listening are better suited for cozier setups. Additionally, consider placementensure you have enough floor space and that the speakers can maintain adequate distance from walls for optimal sound performance.How much bass?If you love hip-hop or EDM, or you crave action-packed movies, big bass is probably your jam, so look for speakers with larger woofers and/or integrated subwoofers. Some models, such as the Definitive Technology DM70 and GoldenEar T66 profiled above, include features like passive radiators to enhance bass clarity. If you prefer a more balanced sound or have neighbors to consider, opt for speakers that offer controlled, precise bass rather than overwhelming power. You can always add a standalone subwoofer later if you crave extra depth.Build quality and designFloorstanding speakers are not just about soundtheyre a visual centerpiece in your room. Consider models with high-quality materials and finishes that complement your decor. Rigid enclosures minimize vibration for cleaner sound, while details like magnetic grilles or premium wood veneers can elevate aesthetic appeal. Consider durability if you have kids or pets.Budget and valueFloorstanding speakers are an investment. With models available at a wide range of price points, its important to set a budget and stick to it. While more expensive speakers tend to come with higher-quality components and advanced technologies, there are plenty of midrange models that deliver exceptional value. Consider your long-term needs and whether additional features, like built-in amplification or room correction, justify a higher price.FAQsQ: Do I need an amplifier for floorstanding speakers? Most floorstanding speakers are passive, meaning they require an external amplifier or AV receiver to function. (The amplifier powers the speakers and processes the audio signal.) Be sure to match passive speakers with an amplifier that offers adequate wattage and impedance for optimal performance. If youre using powered (or active) speakers, such as the KEF LS60 Wireless, above, the amplifier is built-in, so you can connect them directly to your audio source without additional equipment. Q: Do floorstanding speakers need spikes? Spikes, or spike feet, can improve the stability and performance of floorstanding speakers, especially on carpeted floors. They reduce points of contact between the speakers and floor, which isolates speaker vibrations, minimizing unwanted resonances and improving bass control and overall clarity. Spikes are generally the best solution for carpeted floors, because they ensure floor contact and speaker stability even with a high pile. While not mandatory, spikes or other isolation accessories (were partial to IsoAcoustics products) are a worthwhile investment if youre looking to optimize sound quality, particularly in high-end audio setups. Q: How do you break in floorstanding speakers? The concept of speaker break-in divides audiophiles, with some viewing it as a myth, and others arguing its critical for optimal performance. Heres the deal: When you first start using new floorstanding speakers, components like the spider and surround (parts that allow the cone to move) may seem stiff. Playing music over time can help these parts loosen slightly, potentially improving bass response, tonal balance, and overall clarity. However, the difference is usually subtle, and some experts suggest the perceived improvement may be more about your ears adjusting to the sound than any physical changes in the speakers.If you want to break in your speakers, simply play musicpreferably something with a wide dynamic range and a mix of deep bass and crisp highsat a moderate to slightly loud volume for about 2040 hours, no special tracks or settings are required. The most important thing is to enjoy your speakers right out of the boxtheyre designed to sound great from day one.

The new research confirms past anecdotal evidence. Credit: Deposit PhotosShareResearchers say they have made a startling discovery in the Amazon River. But their evidence wasnt collected from the waterit could be seen from shore. After around 219 hours of observations, they can confirm that male Amazon river dolphins (Inia geoffrensis), also known as botos, often roll onto their backs and urinate over three feet into the air. It isnt random. The male botos appear to be peeing with a purpose.Over four years, a team from Canadas CetAsia Research Group traveled to the Amazon river, where they then closely watched river dolphin social interactions. Researchers documented a total of 36 separate instances of male botos deciding to pee while floating in the unconventional position. The findings, presented in a recent study published in the journal Behavioural Processes, support rare, anecdotal stories of past boto behavior.Aerial urination starts with a boto slowly positioning itself upside down, exposing its penis above water, and ejecting a stream of urine into the air, the team explained in their study.Whats more, another male dolphin was swimming nearby about two-thirds of the time, and often approached the urine stream as it landed in the water about three feet away. They sometimes waited in place, but in other instances, they even pursued the pee trajectory using their snout, or rostrum.We were really shocked, as it was something we had never seen before, study author Claryana Arajo-Wan recounted to New Scientist on January 31st.Urine is a common communication tool used by many terrestrial animals such as dogs, bears, and cats. Its seen far less frequently in aquatic environments, but Arajo-Wan and their colleagues offered a few examples in their study. Dominant male African cichlid fish (Astatotilapia burtoni) interpret urine pulses for both reproductive and territorial information. The narrow-clawed crayfish (Astacus leptodactylus), meanwhile, urinates as a sign of aggression. In both of these cases, however, its more about the act of peeing than what is actually in the pee itself.This makes the boto behavior all the more interesting, according to researchers. Dolphins lack a strong sense of both smell and taste, so its still somewhat unclear how they are interpreting the urine streams. The studys authors hypothesized that the male Amazon river dolphins may rely on their rostrum bristles to interpret their fellow botos urine composition, such as hormonal content indicating physical health and social position. A previous study from a team at Stephen F. Austin State University in Texas confirmed bottlenose dolphins (Tursiops truncates) use their tongues to identify other cetaceans through the taste of their urine. Knowing this, its also possible that botos in the Amazon may engage in similar activities. Get the Popular Science newsletter Breakthroughs, discoveries, and DIY tips sent every weekday.

Researchers conceded that aerial urination likely serves a social function beyond waste elimination, but stopped short of landing on any definitive reason beyond possible social or communicative functions. Given their heightened ability to sense acoustical signals, it may be that the aerial urine alerts dolphins to check it out as it hits the water.Regardless of the actual reason, confirming the unique behavior among Amazon river dolphins now opens up the possibility for future study. With more timeand more peeresearchers may eventually learn much more about the aquatic mammals complex social dynamics.

Science & SocietyDo science dioramas still have a place in todays museums?Many exhibit experts believe they still have value but need reimagining The bison diorama at the Natural History Museum of Los Angeles may look placid, but a closer look rewards viewers with a complex ecological tale.Insa Hagemann/laif/ReduxBy Amber Dance8 seconds agoAt first glance, its a simple scene. Six adult bison and a calf mill around a stream. But Matt Davis invites me to look closer. We are at the Natural History Museum of Los Angeles, where Davis is an exhibition developer. As he shows me, theres more to the dioramas tale than a handful of once-living, now-taxidermied bison skins.A well-worn path leads to the stream, and a bison skull sits to the side; this herd has been dropping by for some time. And theyre contributing to the ecosystem. Perched atop that skull and scattered around the scene are birds that feast on bugs kicked up by the bison.
