New scientific analysis determines there are four distinct species of giraffe #science

There are actually four giraffe species in Africa, scientists say
Giraffes are now classified into four distinct species in Africa. Researchers previously thought all giraffes belonged to a single species. On Thursday, a task force of the International Union for Conservation of Nature identified Northern, reticulated, Masai, and Southern giraffes as separate species. This change is based on genetic studies and anatomical differences. Each species faces unique threats and conservation needs. Northern giraffes are the most endangered, with only about 7,000 left…

Autonomy at Levels for Spacecraft
Autonomy at Levels is the idea that autonomy should be embedded within and throughout a spacecraft. Using Systems Engineering methods a spacecraft is typically decomposed into systems, subsystems, assemblies, components, and so on. All these decomposition levels within all the spacecraft's systems, could and should have autonomy elements built in. As a result, the "autonomy system" is made of autonomy elements or units that are integrated, distributed and embedded within the whole spacecraft. T…

On Borel subsets of generalized Baire spaces
We develop descriptive set theory in Generalized Baire Spaces without assuming $κ^{<κ}=κ$. We point out that without this assumption the basic topological concepts of Generalized Baire Spaces have to be slightly modified in order to obtain a meaningful theory. This modification has no effect if $κ^{<κ}=κ$. After developing the basic theory we apply it to the question whether the orbits of models of a fixed cardinality $κ$ in the space $2^κ$ (or $κ^κ$) are $κ$-Borel in our generalized…

US proposes adding seven pangolin species to Endangered Species Act
The U.S. Fish and Wildlife Service has recently proposed listing seven species of pangolins, the most trafficked mammals on the planet, under the Endangered Species Act. If finalized, an ESA listing would prohibit the import and sale of pangolins and their parts in the U.S., except for scientific or conservation purposes. It would also open […]

Spacecraft Safe Robust Control Using Implicit Neural Representation for Geometrically Complex Targets in Proximity Operations
This study addresses the challenge of ensuring safe spacecraft proximity operations, focusing on collision avoidance between a chaser spacecraft and a complex-geometry target spacecraft under disturbances. To ensure safety in such scenarios, a safe robust control framework is proposed that leverages implicit neural representations. To handle arbitrary target geometries without explicit modeling, a neural signed distance function (SDF) is learned from point cloud data via a enhanced implicit geo…
