Astronomers find Webb data conflict with reionization models
Reionization is a critical period when the first stars and galaxies changed the physical structure of their surroundings, and eventually the entire universe. Established theories state that this epoch ended around 1 billion years after the Big Bang......»»
Key gene discovered for regulating rice grain length
Recently, a research team led by Professor Wu Yuejin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, discovered a key gene that can influence rice grain length by regulating cell proliferation, the RGL2 gene. This pr.....»»
Claustrophobic cells slow their own growth, forming beautiful patterns of concentric circles
Like so many organisms on the planet, when cells experience mosh-pit-level crowding, they may just become stressed. Yet unlike most other life forms, cells subject to physical stress from crowding by neighbors can find some relief by dramatically slo.....»»
Scientists recreate sound of Earth"s magnetic flip 41,000 years ago
Approximately 41,000 years ago, Earth's magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth's magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed.....»»
The unintended consequences of brick-and-mortar"s decline
Lately, many big retail brands have been closing physical locations, in what has become known as the "retail apocalypse." Whether the stated reason is declining revenue, or concerns related to "shrinkage" and employee safety in some cities, the impac.....»»
