New dimensions of cryo-electron microscopy uncover ‘multiverse’ of cancer targets for enabling drug discovery

A research team led by Professor Youdong Mao has developed a new method using time-resolved cryo-electron microscopy and machine learning-based 4D reconstruction to visualize the USP14-proteasome system in atomic detail. This reveals a 'multiverse' of parallel reality pathways, allowing for targeted inhibition of cancer cells.

Price noise proves the key to high performing ‘bets against beta’ investment strategies

A study by Thorsten Lehnert reveals that price noise from trading activities of mutual funds explains the success of 'bets against beta' strategies. These strategies, which involve taking short positions in assets with higher betas and long positions in those with lower betas, result in significant positive returns.

Human-made iron inputs to the Southern Ocean ten times higher than previously estimated

A recent study led by Nagoya University found that human-made iron in the Southern Ocean may be up to ten times higher than previously thought, with a 60% contribution from fossil fuel combustion. This could lead to decreased photosynthesis and increased CO2 levels, exacerbating global warming.

Ultrafast dynamics of topological material probed under pressure

The study investigates the nonequilibrium relaxations of hot electrons and coherent acoustic phonons in Sb2Te3 under hydrostatic pressure up to 30 GPa. It reveals a hot phonon bottleneck effect that is effectively suppressed along with the onset of electronic topological transitions.

Stopping C9orf72-linked Dementia in Mutant Mice with Antibiotic Rifampicin

Researchers found that rifampicin improved cognitive function and memory in mice with C9orf72-linked dementia. The antibiotic also reduced formation of protein aggregates, neuronal loss, and microglial activation in brain tissue. This study suggests rifampicin may be a widely effective drug for preventing neurodegenerative diseases.

More about superconducting Ba2CuO4-δ: Band crossover and magnetic phase diagram

The study reveals a single-band paramagnetic metal behavior at intermediate correlation regime, with two antiferromagnetic insulating parent phases at strongly correlated regimes. The researchers also found that Cooper pairs in Ba2CuO4-δ are s+d-wave symmetric due to spin-fluctuation mediated effective pairing interaction.
