The Project CETI glider can autonomously follow sperm whale vocalizations. Breakthroughs, discoveries, and DIY tips sent six days a week. Sperm whales () go deep. They can dive 1,300 to 4,000 feet-deep and also travel as much as 15,000 miles per year.

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.

The team observed the gentle giants two days in a row. Blue whales can be found in every ocean except the Arctic. Breakthroughs, discoveries, and DIY tips sent six days a week. As if soaring above the brilliant blue ocean isn't spectacular enough, the New England Aquarium's aerial survey team recently experienced two back-two-back sightings of blue whales --a little déjà blue, per the aquarium's clever social media post. The first sighting occurred on February 27, when scientists from the Aquarium's Anderson Cabot Center for Ocean Life spotted a blue whale ().

The audio, etched onto a plastic disc in 1949, predates the era when researchers could even recognize whale calls. Breakthroughs, discoveries, and DIY tips sent six days a week. In 1970, a single record would change history.

Motivatedbyrecent advances ingeometric representation learning, we propose a novel GNN architecture for learning representations on Riemannian manifolds with differentiable exponential and logarithmic maps.

In a game of scientific telephone, if you find the food, you find the whales--and sound the alarm. North Atlantic right whales sometimes gather at Jeffrey's Ledge, a 62-mile-long underwater ridge about 25 miles off the coast of Portsmouth, New Hampshire. Breakthroughs, discoveries, and DIY tips sent six days a week. It was a cold and windy week last January, when a group of Maine lobstermen couldn't haul in their traps from Jeffrey's Ledge. The reason why surprised everyone.

Estimating Heterogeneous Treatment Effects (HTE) in industrial applications such as AdTech and healthcare presents a dual challenge: extreme class imbalance and heavy-tailed outcome distributions. While the X-Learner framework effectively addresses imbalance through cross-imputation, we demonstrate that it is fundamentally vulnerable to "Outlier Smearing" when reliant on Mean Squared Error (MSE) minimization. In this failure mode, the bias from a few extreme observations ("whales") in the minority group is propagated to the entire majority group during the imputation step, corrupting the estimated treatment effect structure. To resolve this, we propose the Robust X-Learner (RX-Learner). This framework integrates a redescending γ-divergence objective -- structurally equivalent to the Welsch loss under Gaussian assumptions -- into the gradient boosting machinery. We further stabilize the non-convex optimization using a Proxy Hessian strategy grounded in Majorization-Minimization (MM) principles. Empirical evaluation on a semi-synthetic Criteo Uplift dataset demonstrates that the RX-Learner reduces the Precision in Estimation of Heterogeneous Effect (PEHE) metric by 98.6% compared to the standard X-Learner, effectively decoupling the stable "Core" population from the volatile "Periphery".

To survive, this isolated population of only 2,000 whales needs to be smart about mates. Breakthroughs, discoveries, and DIY tips sent six days a week. Among marine mammals, beluga whales () are particularly difficult to study in their icy habitat. To better understand and protect this endangered species, scientists must piece together bits of their lives from fragments, including one of the most important behaviors of any species--mating. One small population of beluga whales living in southwest Alaska's Bristol Bay appears to have a surprising strategy.

At least 18 new baby North Atlantic right whales have been spotted swimming with their mothers. Breakthroughs, discoveries, and DIY tips sent every weekday. While most of us were feasting on holiday foods over the past few weeks, the New England Aquarium was busy counting North Atlantic right whale () mom-calf pairs off the coast of Florida, South Carolina, and Georgia. "Congrats to all of these North Atlantic right whale moms!" reads a social media post by the aquarium highlighting six recent sightings, including Juno--an over 40-year-old mother with her ninth documented calf spotted on December 27. On January 8, the count jumped up to 18 calves, according to the Clearwater Marine Aquarium .
