The author of the reanalysis stands by his work. (2020-11-18)

Physics can assist with key challenges in artificial intelligence
Two challenges in the field of artificial intelligence have been solved by adopting a physical concept introduced a century ago to describe the formation of a magnet during a process of iron bulk cooling. Using a careful optimization procedure and exhaustive simulations, researchers have demonstrated the usefulness of the physical concept of power-law scaling to deep learning. This central concept in physics has also been found to be applicable in AI, and especially deep learning. (2020-11-12)

A malformation illustrates the incredible plasticity of the brain
One in 4,000 people is born without a corpus callosum, a brain structure consisting of neural fibres that are used to transfer information between hemisphere. 25% of them do not have any symptoms. Neuroscientists from the University of Geneva discovered that when the neuronal fibres that act as a bridge between the hemispheres are missing, the brain reorganises itself and creates an impressive number of connections inside each hemisphere, recreating connections using alternative neural pathways.

Bridges with limb-inspired architecture can withstand earthquakes, cut repair costs
Structural damage to any of the nation's ailing bridges can come with a hefty price of billions of dollars in repairs.

Risk aversion as a survival strategy in ants
Ants are excellent navigators and always find their way back to the nest. But how do they react when an obstacle or a predator blocks their path? An international team including Antoine Wystrach, a CNRS researcher has shown that ants are capable of changing their familiar route to avoid traps thanks to an aversive learning mechanism: by associating visual cues with negative experiences, they can memorize potentially dangerous routes.

Subtle changes, big effects
According to the chaos theory in mathematics, a minute change such as the 'flap of a butterfly's wing' could cause huge changes elsewhere. This seems to hold true at much smaller scales too--for example, within a cell. Scientists from the National Centre for Biological Sciences (NCBS), Bangalore, have now found how a minuscule atomic change in a protein molecule enables the bacterium to shut down its host's immune signaling system. (2019-11-18)

Living bridges
Dense, humid broadleaf forests, monsoon-swollen rivers and deep ravines -- in the Indian state of Meghalaya wooden bridges easily decay or are washed away in floodwaters. Bridges made from steel and concrete are pushed to their limits here as well. But bridges made of living tree roots can survive here for centuries. Prof. Ferdinand Ludwig of the Technical University of Munich (TUM) has investigated these special structures and proposes integrating this extraordinary building technique in modern architecture.
