Scientists Caught Sperm Defying One of Newton’s Laws of Physics : ScienceAlert
Human sperm can swim through surprisingly viscous fluids with ease – and they seemingly defy Newton’s third law of motion to do so.
To figure out how they slither through substances that should, in theory, resist their movement, a team led…

Quantum Time-Freeze: Lasers Lock Quantum States 1,000x Longer
By using tailored pulses of light and powerful X-ray techniques, scientists have discovered how to create long-lived, light-induced quantum states in a copper oxide material—something previously thought to last only trillionths of a second….

NeuralMag: an open-source nodal finite-difference code for inverse micromagnetics
Nodal finite-difference scheme
Existing micromagnetic simulation software usually employs either a finite-difference discretization on regular grids22,32 or a finite-element discretization on irregular grids20,22. The use of regular cuboid grids…

Quantum coherence of a long-lifetime exciton-polariton condensate
Characterisation of the condensation process
To ensure that the polariton condensate forms separately from the reservoir of carriers consisting of electrons, holes and also excitons, we create an optical trap using a spatial light modulator (SLM)…

Enabling data-driven design of block copolymer self-assembly
Sample preparation
BCP samples are generated through a multi-step fabrication process. Here, we will highlight the most significant steps, but additional details can be found in previous works29,30. First, a substrate is chosen, which is typically…
