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 …

Train-Once Plan-Anywhere Kinodynamic Motion Planning via Diffusion Trees
Kinodynamic motion planning is concerned with computing collision-free trajectories while abiding by the robot's dynamic constraints. This critical problem is often tackled using sampling-based planners (SBPs) that explore the robot's high-dimensional state space by constructing a search tree via action propagations. Although SBPs can offer global guarantees on completeness and solution quality, their performance is often hindered by slow exploration due to uninformed action sampling. Learning-…

A note on the sizes of bipartite 1-planar graphs
A graph is 1-planar if it admits a drawing in the plane such that each edge is crossed at most once. Let G be a bipartite 1-planar graph with partite sets X and Y. A 1-disk OX drawing of G is a 1-planar drawing such that all vertices of X lie on the boundary of O and all vertices of Y and all edges of G locate in the interior of O, where O is a disk on the plane. The concept was first proposed by Huang, Ouyang and Dong when they solved a conjecture about the edge density of bipartite 1-planar g…

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.
