Checkers Is Solved
The game of checkers has 5×10^20 possible positions. This paper announces that checkers is now solved. Perfect play by both sides leads to a draw.
Arachnid Collaboration
Samples contained 250 specimens in 12 families. The samples contained at least 16 identified genera.
cross-species collaboration in arachnids.
Talking Bug Identifier
Is it a cricket or a katydid? Help your budding entomologist identify more than 50 real live bugs – simply by answering a series of yes or no questions.
the future is almost here now.
Positronium
When an electron meets a positron, their mutual annihilation may ensue or positronium, a briefly stable, hydrogen-like atom, may be formed. The collision of 2 positronium atoms can result in gamma radiation.
Planet sized diamond
BPM 37093, now known as the biggest diamond in the galaxy, 50LY away from Earth in the constellation Centaurus, has a diameter of 4000 km.
conspiracy-minded folk would call it an artifact of a kardashev type II civilization 🙂 also, earth is 6000 km.
Wolbachia
Wolbachia may be the most prolific parasite in the world—a “pandemic”. This parasite has implanted itself inside the cells of 70% of the world’s invertebrates, coevolving with them.
Rubbery metal
composite consisting of ceramic particles embedded in a metal matrix. The metal provides strength and stiffness, while the ceramics have a property known as ferroelasticity, meaning vibrations are converted into tiny rotations of crystals in the material.
Agression Detection
an application of the sound detection technology where the system is set to detect verbal aggression. As soon as the sound contains the indicators of aggression, a signal is sent which can be used e.g. to activate the nearest observation camera.
Variable liquid mirrors
They have no mechanical parts, consisting of just a fluid held inside a chamber in such a way that the fluid’s surface forms a lens shape. Applying an electric field to the fluid changes the shape of its surface.
