The Y chromosome is home to surprising jumping genes
The Y chromosome is home to surprising jumping genes Stephanie Baum Scientific Editor Robert Egan Associate Editor The humble Y chromosome may be the smallest chromosome in the mammalian genome (and getting even smaller), but it is mighty: Genes on the Y chromosome are critical for fertility in males. In a new study in the journal Current Biology, researchers at the University of Michigan Medical School have studied deer mice to outline how the Y chromosome defends itself against decay by...
Octopuses learn mirror-guided navigation to locate prey
Octopuses learn mirror-guided navigation to locate prey Lisa Lock Scientific Editor Robert Egan Associate Editor Octopuses are remarkably intelligent creatures, as was demonstrated by Inky the Octopus's famous escape from the National Aquarium of New Zealand through a drainpipe back to sea in 2016. A new Dartmouth study shows octopuses can use mirrors to find food out of sight, demonstrating spatial cognitive abilities. The results are published in Current Biology.
Beyond Prompt-Based Planning: MCP-Native Graph Planning-based Biomedical Agent System
Announce Type: new Abstract: Biomedical agents promise to automate complex biological workflows, yet current systems face two fundamental bottlenecks: bioinformatics tools are highly heterogeneous in interfaces and execution environments, while agent planning still relies on flat prompt-retrieved tool descriptions. As biomedical software ecosystems grow, this coupling between tool coverage and context size leads to tool confusion, unstable planning, and inefficient execution. We introduce...
Memristor-Based Spiking Neural Network Accelerator for Bio-inspired Interception Task
arXiv:2605.31299v1 Announce Type: new Abstract: Spiking neural networks (SNNs) provide event-driven and low-power computation inspired by biological neural systems, but current implementations rely on von Neumann graphics processing units (GPUs) and central processing units (CPUs) platforms, where memory and computation bottlenecks limit energy efficiency. To address this challenge, this paper proposes an analog memristor-based spiking neural network (SNN) accelerator that integrates...
Laser beam builds cell-like protein networks without chemical modification
Laser beam builds cell-like protein networks without chemical modification Lisa Lock Scientific Editor Robert Egan Associate Editor Networks of protein fibers play important roles in living cells. To understand the dynamical behavior of these networks, model networks are needed to perform in vitro studies. However, fabrication of protein networks similar to those in cells has proved difficult, as current methods could affect the biological function of these proteins—ultimately impacting our...
Auditable recovery of single-cell RNA-seq zeros with SPARE
In Single-cell RNA-seq, observed zeroes are the mix between biological absence and technical limitations. However, current evaluation metrics fail to distinguish between these two states, focusing on reconstruction accuracy rather than the biological validity of edits. We introduce SPARE, a partition-aware framework that audits the imputation process by cataloging observed zeros as edited, unchanged, or marker-vetoed prior to sequence reconstruction.
Octopuses use mirrors to find food they cannot see
Octopuses use mirrors to find food they cannot see Octopuses just joined an exclusive intelligence club by learning to use mirrors to find hidden food. - Date: - June 5, 2026 - Source: - Dartmouth College - Summary: - Octopuses may be even smarter than we thought.
Evaluating agentic AI for biological discovery in autonomous and copilot settings
Advances in large language models (LLMs)-based artificial intelligence (AI) agents have improved their ability to execute structured analytical workflows, including standard bioinformatic pipelines for biological discovery. However, computational biology rarely consists of deterministic pipeline execution alone. Biological datasets are heterogeneous and noisy, and meaningful discovery often requires open-ended hypothesis generation and iterative reasoning over multimodal evidence.
Beethoven’s 200-year-old death mystery takes a shocking turn after DNA analysis
On a stormy evening in 1827, Ludwig van Beethoven died in Vienna after years of declining health that had already pulled him out of public life. He had been confined to bed for months, struggling with swelling, jaundice, and exhaustion that made even small movements difficult. By then, his hearing loss was already part of history, not just biography.
Jeff Bezos Is Funding a Wild Hunt for the Brain’s ‘Core Algorithm’
Rob Williams knows how to pitch Jeff Bezos: You write a press release as if your product has already been built. Bezos reads it and gives a thumbs up or down. Williams went through this process a lot as an executive on Amazon’s “S-team,” in charge of software products such as Alexa, until his departure last fall.
