From pond to polymer: Chemists create fully recyclable plastics using whole-cell algae
A team of chemists is pioneering a new approach to creating plastics made from whole-cell algae and common chemical components. These biohybrid plastics are strong, highly adaptable, and fully recyclable.

Largest planar graphs of diameter $3$ and fixed maximum degree -- connection with fractional matchings
The degree diameter problem asks for the maximum possible number of vertices in a graph of maximum degree $Δ$ and diameter $D$. In this paper, we focus on planar graphs of diameter $3$. Fellows, Hell and Seyffarth (1995) proved that for all $Δ\geq 8$, the maximum number $\mathrm{np}_{Δ, D}$ of vertices of a planar graph with maximum degree at most $Δ$ and diameter at most 3 satisfies $\frac{9}{2}Δ- 3 \leq \mathrm{np}_{Δ,3} \leq 8 Δ+ 12$. We show that the lower bound they gave is optimal,…

A Fast and Light-weight Non-Iterative Visual Odometry with RGB-D Cameras
In this paper, we introduce a novel approach for efficiently estimating the 6-Degree-of-Freedom (DoF) robot pose with a decoupled, non-iterative method that capitalizes on overlapping planar elements. Conventional RGB-D visual odometry(RGBD-VO) often relies on iterative optimization solvers to estimate pose and involves a process of feature extraction and matching. This results in significant computational burden and time delays. To address this, our innovative method for RGBD-VO separates the …

Dynamic Triangulation-Based Graph Rewiring for Graph Neural Networks
Graph Neural Networks (GNNs) have emerged as the leading paradigm for learning over graph-structured data. However, their performance is limited by issues inherent to graph topology, most notably oversquashing and oversmoothing. Recent advances in graph rewiring aim to mitigate these limitations by modifying the graph topology to promote more effective information propagation. In this work, we introduce TRIGON, a novel framework that constructs enriched, non-planar triangulations by learning to…

Polymer-protected DNA sensors enable two-month storage for 50-cent disease diagnostics
Using an inexpensive electrode coated with DNA, MIT researchers have designed disposable diagnostics that could be adapted to detect a variety of diseases, including cancer or infectious diseases such as influenza and HIV.

Is there any evidence that a brain implant for restoring vision will give more functional vision than a noninvasive sensory substitution device? Don't speculate. https://www.youtube.com/playlist?list=PLmrvukzbS44SMVxMLRpd-_iTpy_Cj5liB
No, there is no evidence from current studies or comparisons that brain implants for vision restoration provide more functional vision than noninvasive sensory substitution devices. Available direct comparisons, such as those examining retinal or cortical implants (e.g., Argus II) against devices like The vOICe, indicate the opposite: noninvasive options demonstrate broader functional outcomes in tasks like object recognition, grasping, and navigation, with better resolution, field of view, and…

Direction Informed Trees (DIT*): Optimal Path Planning via Direction Filter and Direction Cost Heuristic
Optimal path planning requires finding a series of feasible states from the starting point to the goal to optimize objectives. Popular path planning algorithms, such as Effort Informed Trees (EIT*), employ effort heuristics to guide the search. Effective heuristics are accurate and computationally efficient, but achieving both can be challenging due to their conflicting nature. This paper proposes Direction Informed Trees (DIT*), a sampling-based planner that focuses on optimizing the search di…
