Thermo-chemical power generation integrated with forced convection cooling to create a self-sustaining liquid cooling system

This technology resolves the longstanding unaddressed issue of the loss of free energy component of the thermal energy that accompanies forced convection cooling, a process that has widespread use in the modern world.

Efficient bottom-up synthesis of new perovskite material for the production of ammonia

This new synthesis process can be carried out at temperatures immensely lower than that of traditional methods for the synthesis of perovskite-oxide materials and in much less time, and the produced perovskite outperforms all its competitors for producing ammonia.

Small, fast, and highly energy-efficient memory device inspired by lithium-ion batteries

The device, which has an extremely low energy consumption, may be key for the development of more energy-efficient and faster RAMs, which are ubiquitous in modern computers.

DNA is only one among millions of possible genetic molecules

Scientists computed a zoo of millions of alternate genetic polymer molecular structures, giving context for why biology encodes information how it does, and providing potential leads for new drugs and a guide to searches for extraterrestrial biology.

Not so selfish after all — Key role of transposable elements in mammalian evolution

A scientist at Tokyo Tech has revealed a key role for "selfish" transposable elements in the evolution of the mammary gland, a defining feature of all mammals.

Scientists find biology's optimal "molecular alphabet" may be preordained

The amino acids, a fundamental set of life's building blocks, may have been adaptive throughout their evolution, suggesting a possible universal biological language.

Japan's MMX Martian Moon Probe is unlikely to bring back dangerous Martian microbes

A Japanese research team has assessed the probability that Martian microbes that might have contaminated Mars' moons would be returned to Earth by JAXA's Martian Moons eXploration (MMX) sample return mission.

New model illuminates enigmatic layer at Earth's core-mantle boundary

A new model shows that Ultra-low velocity zones(ULVZs) evolve into isolated "islands" of dense material, exposing the lower mantle to the liquid outer core away from ULVZs and reflecting the form of deep circulation within the Earth.

Terrestrial magma ocean origin of the Moon

For the first time, the researchers conducted 3D simulations of the giant impact when the early Earth had a magma ocean on its surface. Their simulations clearly show that the presence of the magma ocean helps to form the moon, which originated from the Earth's material, solving the long-standing issue of giant impact simulations.
