This adorable sea lion has to eat five to eight percent of its body weight every day to stay healthy and hydrated. Breakthroughs, discoveries, and DIY tips sent six days a week. Over the long and complicated course of evolutionary history, mammals independently turned towards water to make a home multiple times. While many of the warm-blooded animals that abandoned dry land for a watery habitat no longer exist, we still have plenty of stunning examples: Think dolphins, whales, manatees, porpoises. There's even a whole suborder of carnivores called the pinnipeds, which includes seals, sea lions, and walruses who move between land and water.

Environment Conservation Ocean Florida can't decide if its official saltwater mammal is a dolphin or a porpoise They are not the same animal. Dolphins (right) are more common in Florida, while porpoises (left) are spotted much less frequently. Breakthroughs, discoveries, and DIY tips sent six days a week. States have a surprising number of official symbols . While most people would expect them to have an official motto, seal, and flag, there can also be a state beverage, muffin, soil, fossil, and poem, to name a few.

A 2024 study found that cats learn to associate images with words faster than human babies. Breakthroughs, discoveries, and DIY tips sent every weekday. "My cat always watches my phone as I text or read a book," someone wrote on Reddit . "Even right now she is on my shoulder, intently watching what I am typing on this post. Can she read or is she just interested in what I am doing?"

Here we present a new class of optimality for coding systems. Members of that class are displaced linearly from optimal coding and thus exhibit Zipf's law, namely a power-law distribution of frequency ranks. Within that class, Zipf's law, the size-rank law and the size-probability law form a group-like structure. We identify human languages that are members of the class. All languages showing sufficient agreement with Zipf's law are potential members of the class. In contrast, there are communication systems in other species that cannot be members of that class for exhibiting an exponential distribution instead but dolphins and humpback whales might. We provide a new insight into plots of frequency versus rank in double logarithmic scale. For any system, a straight line in that scale indicates that the lengths of optimal codes under non-singular coding and under uniquely decodable encoding are displaced by a linear function whose slope is the exponent of Zipf's law. For systems under compression and constrained to be uniquely decodable, such a straight line may indicate that the system is coding close to optimality. We provide support for the hypothesis that Zipf's law originates from compression and define testable conditions for the emergence of Zipf's law in compressing systems.

Environment Conservation Ocean Dolphins may be getting an Alzheimer's-like disease due to this neurotoxin The neurotoxins, found in algal blooms, primarily affect the body's nervous system. Breakthroughs, discoveries, and DIY tips sent every weekday. For marine biologists, dolphins are often viewed as sentinel species, or animals that shed light on the health of the ocean . Along with whales, porpoises, and other cetacean species, dolphins are one way that researchers know to sound the alarm about environmental hazards that might affect the ocean as a whole and potentially humans. In this context, researchers have connected neurotoxins from algal blooms to brain changes associated with an Alzheimer's-like disease in dolphins in Florida.

'These strandings happen fast, and every minute counts.' Breakthroughs, discoveries, and DIY tips sent every weekday. Chipman's Cove in Wellfleet, Massachusetts can be treacherous for the sea creatures that must navigate it. Shallow bays, complex tidal flats, and an arm of land that shelters it from the greater harbor and Cape Cod Bay make it a great summer destination for humans and a notorious stranding hotspot for marine life. Early on Saturday, September 13, worried individuals called the International Fund for Animal Welfare (IFAW) stranding hotline (its 508-743 9548, in case you ever need it), warning the nonprofit that a number of dolphins were in Chipman's Cove.

A new large language model AI system may soon allow humans to converse with dolphins. Scheduled to debut in the coming months, researchers will test to see if DolphinGemma and its companion Cetacean Hearing Augmentation Telemetry (CHAT) system can translate and mimic some of the mammal's own complex vocalizations. If successful, the breakthrough may represent the culmination of over four decades' worth of work, documentation, and conservation efforts.. Dolphins are some of the Earth's smartest and most communicative animals. Their social interactions are so complex that researchers at the Wild Dolphin Project (WDP) have spent the last 40 years attempting to decipher them. In the process, WDP has amassed decades' worth of underwater audio and video documenting a single community of Atlantic spotted dolphins in the Bahamas.

This report introduces Dolphin, a large-scale multilingual automatic speech recognition (ASR) model that extends the Whisper architecture to support a wider range of languages. Our approach integrates in-house proprietary and open-source datasets to refine and optimize Dolphin's performance. The model is specifically designed to achieve notable recognition accuracy for 40 Eastern languages across East Asia, South Asia, Southeast Asia, and the Middle East, while also supporting 22 Chinese dialects. Experimental evaluations show that Dolphin significantly outperforms current state-of-the-art open-source models across various languages. To promote reproducibility and community-driven innovation, we are making our trained models and inference source code publicly available.

After nine months stuck on the International Space Station (ISS), NASA's Butch Wilmore and Suni Williams finally made it back home last night. The duo splashed down off the coast of Florida aboard SpaceX's Crew Dragon capsule, having arrived at the ISS way back in June. While Wilmore and Williams will be relieved to be back on solid ground, their return has ignited a slew of conspiracy theories - with many sceptics critical of the splashdown in particular. Upon arrival, the capsule was circled by an inquisitive pod of dolphins, which many social media commentators are describing as'fake' and computer-generated. Others have taken it even further, suggesting the entire mission footage from departure to landing was created by a sophisticated AI tool.

We look at reasoning on GSM8k, a dataset of short texts presenting primary school, math problems. We find, with Mirzadeh et al. (2024), that current LLM progress on the data set may not be explained by better reasoning but by exposure to a broader pretraining data distribution. We then introduce a novel information source for helping models with less data or inferior training reason better: discourse structure. We show that discourse structure improves performance for models like Llama2 13b by up to 160%. Even for models that have most likely memorized the data set, adding discourse structural information to the model still improves predictions and dramatically improves large model performance on out of distribution examples.
